Today we'll be discussing Dr. Yardeni's newest book in Praise of Prophets. We'll also be talking about the economy, where we've been, and where he thinks we may be going. So with no further ado, let me introduce Ed Yardeni. Welcome to the podcast, Ed. Thank you very much. Ed, thank you for joining us today. You've published a couple more books since I talked with you last. The latest book that you wrote, I found very interesting. It's called In Praise of Prophets. This book is just the latest in a series of topical studies that you've done, starting with the yield curve, stock buybacks, Fed watching, two books on Fed watching, and also S&P earnings and valuation and the pandemic. And this all followed your original book on predicting the markets of professional autobiography. So I want to specifically focus on this book, though, because I found it very interesting. It's really something that I think has been bothering me as an investor, and I think clearly has been bothering you also. It's about profits. We've had a lot of discussion in the media, and I can't get too political in this podcast, but there's a difference of opinion, if you will, about profits and where we should be going as a nation. And what you intend to do with the book is to clear that up, at least from your view as an economist. So with that, could you tell us what the main idea of the book was? Sure. I've observed over the years that profits tend to be the driver of economic prosperity. I mean, it's really pretty simple and straightforward to see it, to observe that it's profitable companies that expand. They hire more workers. They expand their capacity, so they're ordering more goods, capital equipment, and so on. Whereas companies that are not doing so well are actually losing money have to retrench. They have to cut back employment. They have to try to sell off some of their assets. And the more profitable companies we have, the better the overall economy is going to do, the better overall society will do. Because, again, it's profitable firms that hire people, and that's the name of the game when we're talking about economic prosperity. We're not rooting for companies themselves to be prosperous and no one else to be prosperous. Obviously, companies can't be prosperous if their customers aren't prosperous. So this is sort of a defense of what I call entrepreneurial capitalism, which I think needs to be distinguished always from crony capitalism. There's aspects of capitalism that I certainly don't agree with, don't favor, and I criticize in the book. But on the other hand, the entrepreneurial capitalism often gets kind of wrapped up into that conversation and gets misrepresented as based on greed and selfishness and exploitation of workers. And the reality is that's not the reality of our economy. Ed, you touched on right away on the difference between entrepreneurial capitalism and crony capitalism. And I'd like you to dig into that a little bit more. I mean, what is the difference? In a word, lobbyists. Okay. To keep it real simple. I am an entrepreneurial capitalist. I do pretty well. I've got a small company, I've got employees, but I'm not doing so well where I have extra money to hire lawyers and lobbyists to work with politicians in Washington to try to protect my business. That's what it really gets down to, correct? Yeah, politics. Yeah, I mean, I don't get involved in politics. I get involved in trying to satisfy my customers, whereas crony capitalists have done so well that they forget that it was entrepreneurial capitalism that gave them their success and their wealth and it was their focus on their customers that made them successful. And it's sad when entrepreneurial capitalists do so well that they morph into crony capitalists by relying more and more on the government to create regulatory impediments to competitors to compete with them, to put them out of business even. Now, would some of that be in defense of retaining jobs? Well, that always is the excuse, right, is the reason that the government needs to subsidize my business or the reason the government needs to protect my business from both domestic and foreign competition is because if the government doesn't do that, then I'm going to have to shut down and all these people that I employ will lose their jobs.  It's going to be politicians and companies that interact through lobbyists that will decide who succeeds and who doesn't. And that's fundamentally to the detriment of who I'm trying to satisfy and make as well off as possible. And that's consumers. Sometimes it's better to let the market make the decisions even if it's painful because the ultimate result is good for consumers and good for even the employees that may lose jobs and find them with companies that are better managed and better aimed at satisfying their customers. More sustainable, perhaps. Yeah. What I took away from your book, and I hadn't really realized this huge number of S-Corps, sole proprietors, partnerships relative to C-Corps and the breakdown of national income between the large C-Corps, not all of them are large, to S-Corps and solo practitioners. Could you elaborate on that? Yeah. Well, in corporate profits, the data that comes out with GDP, that is the corporate profits of both C-Corporations and S-Corporations. C-Corporations tend to be large, but not always. There's plenty of small C-Corporations, but they're owned by shareholders and they pay out dividends and they're taxed twice. They're taxed on their profits and then the shareholders are taxed on their dividends. S-Corporations are so-called pass-through entities, and what that means is that they're owned by fewer shareholders, which is one of the requirements, and if they pass the IRS requirements for filing as S-Corporations as pass-throughs, then their profits show up in the national income accounts, but their profits are then paid out as dividends to their small number of shareholders, and then the shareholders pay their personal income taxes on those dividends. So they're pass-throughs and there are quite a few of them, and there's even more sole proprietorships that are owned by only one person and also are pass-throughs. Whatever profit they have is passed through to the proprietor. They don't have to pay, they don't pay any corporate tax, they just pay personal income tax on proprietor's income, and then there's partnerships which are also included in the data. And when you add them all together, you find out that pass-throughs, including S- and proprietorships and partnerships, pass-throughs account for more than half of payroll employment in the United States. And they've been growing very rapidly, which is an indication to me that a lot of people are entrepreneurial in spirit and in action. A lot of people have decided they don't want to work for somebody else, they want to have their own company, and they start their own company, and as long as they succeed, at some point they probably need to hire people. The old days, the United Kingdom was often described as a nation of retailers, of small shops, of shopkeepers. We really have continued to evolve into a nation of proprietorships and S-corporations and partnerships. Those are all entrepreneurs. Very few of them are in a position where they can go higher lobbyists and get political about their business. So as these entrepreneurs are successful and they start to grow and they start hiring people and some of them become publicly traded companies, it seems like at that point they tend to become villainized in many ways because of this thing called income inequality. In other words, the people who grew that company and went public and yes, they became wealthy as a result somehow don't deserve that wealth and that wealth needs to be shared with the quote-unquote stakeholders as opposed to the shareholders. Can you talk about the difference between stakeholders and shareholders? Well, first with regards to the income inequality issue, a lot of the income inequality we see in our society has a lot to do with demography. Frankly, simply with age. I mean, young people don't earn very much and older people tend to earn a lot more and that kind of makes sense that that's the way it should be because young people aren't experienced. They may be very well educated but they aren't particularly experienced, particularly in the business that they eventually wind up joining and older people have more skin in the game than develop more. So it's true that there's income inequality but a lot of it's related to where you are in the age profile and it's generally younger people that go out on their own and start companies and take some risks and if they're successful then they start to hire and if they're very successful they start to enjoy some significant wealth and odds are they're going to reinvest a good part of that wealth back into their business and hire some more people but as they do that their companies become more valuable, their shareholders and their companies, they might even go public which increases potentially the value of their company. I mean, very few entrepreneurs are going to go public unless Wall Street Investment Banker tells them that your stock price is going to value your company a lot more than you realize and so yeah, they get wealthy and most of the wealth inequality is related to equity ownership of businesses by sole proprietors as well as equity ownership of publicly traded companies like C corporations but as you said when we look at the notion that entrepreneurs are robber barons which is sort of historically what entrepreneurs have been described as being once they've succeeded completely misses their success originated from the fact that they provided goods and services that were wanted that were needed that were highly prized by their customers by their consumers it's their customers that made them rich they didn't rip off their workers they didn't rip off their customers I mean people like that you know don't stay in business for very long not in a free marketplace because the consumers walk away from them and their workers walk away from them they only stay in business if they got political clout and political support but we have some of that but we also have lots of entrepreneurship and what we understand have to understand about entrepreneurs is that they are driven by the profit motive to bring us goods and services that improve our standard of living that's the way they're going to get rich so first and foremost their top concern isn't a selfish concern isn't that how am I going to get rich it's how am I going to satisfy enough consumers so I first will stay in business and I won't lose everything I put into it then all of a sudden they say my goodness I've done it and my the customer is just coming in and it's it's gone viral people are are talking to each other and saying you know this is a good product and suddenly I'm rich now some of these people who get very rich what do they do they as I said they put it back in their business others get so rich that they become venture capitalists they send some of their money to firms in Silicon Valley and say okay that's a pretty good idea I'm going to invest in that and so they are the wellhead of prosperity they are the wellhead of risk taking and the willingness to try to come up with goods and services that increase everybody's standard of living you talk on your book about upward income mobility well I think most Americans are aspirational most Americans would like to do better and I think a lot of upward income mobility has to do with an entrepreneurial capitalist system it provides the opportunity to have upward income mobility work hard provide you know what what your employer needs you to provide to make that their business succeed or do that as an employer work hard motivate your employees and sell good products and services that consumers want and you wind up enjoying upward income mobility now upward income mobility tends to occur during periods of prosperity more people wind up making more in an economy that's growing and prospering than one that isn't we actually get the worst the worst income inequality and the worst wealth inequality during periods of prosperity when the rich are getting richer but why are they getting richer well because people are buying what they're selling and they wind up doing extremely well but again it's like the Henry Ford insight Henry Ford decided to raise the money he pays his workers because he wanted to make sure he had enough customers who could afford to buy his cars and we're well past that point in our economy in our society but it's definitely in the best interest of entrepreneurs to come up with the outstanding goods and services that'll make them prosperous and then to share the prosperity the market kind of forces them to do that maybe maybe they don't do it completely by design or they're not completely motivated to do that but the market definitely forces them to share the wealth with their employees with their shareholders and with society at large by providing these goods and services at lower and lower prices when we're listening to the news media about income inequality what we're not told it appears is that there are different ways to measure income and you know just using a minimum wage for example is not a great way to measure income right just using income is not a great way to measure wealth either I know a lot of people who are multimillionaires who are getting affordable care tax credits because their income is low and the government says if you have low income then you are in poverty or some level of poverty even though it doesn't measure wealth so could you talk about the problems of measuring income and the different ways of which we should be measuring it well on the progressive side I've observed over the years that they they like to they do like to show that there's data that support their position but they always seem to use the same series over and over again without recognizing the flaws in the data they're using and I think it's mostly because the data supports their story and as long as it supports that story the data must be good but I I've done a lot of work on on the income data and concluded that one series that they particularly like is one put out by the census to measure poverty and that is it's a median household income so it's the household in the middle if you will median household income and that's divided by the CPI now there's several problems with that for starters the census data is based on surveys they ask people how much money income do you have are you making and so they're basically asking collecting data on an income series that is pre-tax so it doesn't include any of the tax credits that progressives have succeeded in putting into the tax system doesn't reflect the progressiveness of the tax system doesn't reflect non-money sources of income like Medicaid and Medicare and food stamps so you're never going to win that debate because that that series is always going to show that the median household isn't doing very well if you don't factor in all the programs that the progressives have successfully provided in the book I I try to be balanced I try to give be fair to the progressives they've accomplished a great deal I mean social security nobody argues about that really anymore and we've got Medicaid and Medicare there's a lot that they've accomplished but if if they don't show that in the data that they're using you know they're always going to finding fault with the system and so well that's one problem the CPI tends to be upwardly biased it's widely recognized by economists that it's upwardly biased and there are other measures that economists particularly the Fed has endorsed the personal consumption expenditure deflator as an alternative to the CPI and when you use that indicator you find that real incomes have increased about one to one and a half percent per year since 1995 whereas the data series that the progressives have been promoting basically stagnated over that whole period you're still going to hear progressives just kind of blurred out unchallenged that the data confirms that the average family the median family has seen their income stagnate for decades and and that all of the benefits of economic growth have gone to corporations and and the wealthy and that's just not correct it's just it's just not true the reality is there has been no stagnation in real wages one thing that's in the sights of the proposed tax bill is this idea of corporate buybacks and how stock buybacks are a bad thing and that they this money should be going to the workers and the stakeholders instead of the shareholders you wrote a whole book on this can you tell us some insight well we don't really have particularly good data on buybacks what I do see is that when we look at the S&P 500 and we look at the growth rate on a year-over-year basis in earnings per share versus the total earnings aggregate earnings of these corporations what we find is that it's not much of a difference in other words our companies really spending hundreds of billions of dollars to buy back their shares and on balance the S&P 500 winds up only getting a boost of about one percent per year from the this buyback activity now the problem is that's the macro picture when you actually dig down and look at the S&P 500 there are in fact lots of companies that buy back their shares and that significantly increases their earnings per share because there are fewer shares outstanding but then there's also a lot of other companies where the buybacks don't seem to be having that effect well we don't really have good data on but we know anecdotally it exists is companies do pay their employees part some of their compensation in stock and in stock options and it's not just the top three or four or five people that are part of these plans and I think what happens is when companies like that pay out compensation in stock to avoid dilution to avoid reducing their earnings per share because there's more stock being issued as compensation they turn it right around and take the money the cash that they didn't pay out as cash for compensation and buy back shares so that net net that doesn't have an adverse impact on their earnings per share and I think there's quite a few companies that that do that so I don't think we want to discourage companies from paying some of their compensation in stock because it does give employees skin in the game and it does give them a benefit I mean the reality is this the stock market has been trending higher for years and employees who've been benefiting compensation plans by getting some of their pay in stock have done extremely well and I don't think we want to discourage that I also don't think that Washington should get involved in micromanaging corporate financial matters it should really be up to corporations to deal out with that having said all that I do recognize that there is a problem of some CEOs being egregiously overpaid so what's again it's not as though I disagree with everything progressives have to say I think they are right that there are some CEOs that are egregiously over overpaid but I think it's really up to the shareholders or if Congress wants to get involved in that area they've already have done that and and mess things up it was it was back in Bill Clinton's administration that Congress very concerned about CEOs making too much money and what they did is they said okay up to a million dollars in compensation per CEO is tax deductible to the corporation anything above that isn't so corporations started issuing stock and stock options to these CEOs who got famously rich thanks to this progressive legislative change so be beware of what you wish for beware of unintended consequences when you meddle around with the economy but unlike stock that's just bought back to increase earnings per share stock that's bought to basically get reissued to employees this is an expense item I mean this doesn't get away that's correct it's an expense item but let's just take I don't know somebody who's making 100,000 you give the employee 10,000 or 20,000 in stock so instead of paying out 10 to 20,000 dollars in cash you take that cash and go and buy the stock in the market so that you're not diluting earnings per share so absolutely the the full 100,000 is expense from from the corporate income statement so roughly you think what half of all stock buybacks are basically expense like it would be a salary it's it's hard to say the data I've seen which is very flimsy data is something like 20 25 percent of employees get some sort of stock compensation which is a pretty large number of people it's not you can't account for that those kind of numbers were just a a couple of the people at the top but overall you you do know you did see that stock buybacks in the aggregate maybe increase earnings per share by one percent per year correct but what percentage of the stock market is being bought back every year was it it's three four percent something like that yeah so yeah the market is huge so so could we reasonably say then that at least half of all buybacks maybe even more it's just going towards compensation that's expense it's a real possibility I just don't I like to have the data to make my point I mean I'd love to say that and say you know this this insight proves my point but I can't really prove it with the data so at this point I'd rather just say that what I do believe is I have some data confirming the story is that something like 25 percent of people working people get some participation in a compensate in a stock compensation plan okay fair enough but this is a target now of Washington I mean they yeah some people in Washington have decided that stock buybacks for whatever reason are not a good thing for America yeah they believe that the corporations should be taking that money and spending more on the capital equipment and productivity and wages they've often compared the amount of money that's spent on buybacks to corporate profits and said my god it's a hundred percent a hundred percent of corporate profits is going to buybacks and buybacks plus dividends account for a hundred percent of corporate profits what they don't seem to appreciate as a basic accounting statistic in corporate finance and that is corporate cash flows equal to after tax corporate profits plus depreciation and depreciation is huge much bigger than corporate profits so companies have been spending and we've got record capital spending going on even as we've had sizable buybacks so where did that all that money come from for the capital spending and the answer is well it's cash flow it's cash flow to a logic stand based on the depreciation allowance which is a essentially a tax shelter so that you can write off assets that are depreciating and have money to to reinvest in a newer equipment the proposal that went to the senate recently said that there will be a one percent tax imposed on all corporate buybacks with some exceptions stock that goes into an ESOP plan and a few other things don't you think that if that actually passed that corporations would change the way they do things as far as compensation to their employees that 25 which is currently getting stock no it's a it's a piddling number but it's really just opening the door to Washington having more say in the way corporations manage their finances which makes no sense whatsoever since very few of politicians in Washington have ever managed a company or should have any say in managing a company again against the concept of shareholders versus stakeholders congress I guess views itself or some some politicians use themselves as stakeholders in every corporation in America that somehow they have a right to metal and to tell corporations what they should be doing with their finances with their employment with their capital spending with their productivity but that makes no sense that's not the way the system is supposed to work it's supposed to be a capitalistic system and shareholders should be the ones overseeing what their businesses are doing the name of the book called the praise of profits and it's just a treasure trove of some great information about income and the measurement of income and different profits and and the uses of profits and so forth and it's just adds to your knowledge about how America works and I think that the best thing I guess like I just sum it up with just one line that you wrote actually in the last page of the book and you basically said most Americans have never been better off than they are today thanks to record profits and record productivity which are fueling widespread prosperity do you want to comment on that well that line and really does encapsulate the whole point of the book is that you know we should praise profits rather than curse profits profits is not a four-letter word profits really is the source of economic prosperity the profit motive drives businesses to provide the very best goods and services at the lowest price relative to the competitors but it's important that they have competitors it's important that we don't corrupt the system with prony capitalism with too much politics I mean it's kind of too late for that it's already happened but it's important that we allow entrepreneurs to constantly challenge that system to come out of nowhere with better goods and services at lower prices and say see I can do this better than these big companies who've been established and doing it for a long time and yet aren't giving you the kind of quality or prices that the consumer really should have so yeah the whole focus of the book is that you know we need to have a lot more respect for profits and a lot better understanding of the role of profits and creating the prosperity that we've all enjoyed and I would hope that some people would re-examine their assumptions because it's widely believed that Americans aren't the well off that their incomes have stagnated that their standard of living is pathetic and that income inequality has gotten so bad that only a few people really are enjoying the benefits of this great country and that's just not not so well thanks that's a great summary let's get into the economy sure and what happened in 2021 where are we now and where do you think we're going in 2022 and let's start with corporate profits right the corporate profits have been remarkably strong they've come back dramatically on a year-over-year basis in the second quarter we were up like 90 percent that reflects the fact that they were extremely depressed during the second quarter of 2020 because of the the lockdowns but it's really quite extraordinary the extent to which corporate profits have made a comeback corporate profit margins have gone to all-time record highs and the stock market anticipated that and as you might recall there are a lot of people in the media who were kind of like looking at the stock market and they said this is not right I mean why is the stock market having such a good time when the economy is doing so terribly and the reality is corporate profits underneath of all that were rebounding dramatically and as corporate profits rebounded guess what companies started to bring back their employees and started to expand again and so it's all come together rather nicely I think 2021 is a year where the the demand shock that was created by excessively stimulative fiscal and monetary policies created a supply disruption shock I think that's really what's been happening this this in 2021 is it's not that suddenly the supply chain system kind of collapsed for no good reason it just got overwhelmed by demand look people had cabin fever from the lockdowns and as soon as the lockdowns were gradually eased they went out and bought a lot of goods they couldn't buy services so they bought a lot of goods and then the government sent three rounds of relief checks and I think the first one was necessary the second one not so much and the third one I think created the demand shock that has led to the supply disruptions just way too much demand relative to the supply system so the supply system has been disrupted and the result has been higher inflation this whole business cycle that we've had since we hit a bottom in the second quarter of last year has been like a business cycle on steroid and speed we had a horrible recession last year that only really lasted two months which was March and April we've never had a lockdown recession and then we've had this extraordinary recovery to the point where we were back to where we started pre-pandemic in record GDP territory by the second quarter of this year and now as part of this accelerated business cycle we're seeing something we haven't seen for a very long time and that's a real pickup in inflation well that gets right into my next question Chairman Powell and others have been talking about this transitory inflation versus permanent inflation of course they've been trying to get the inflation rate up to two percent for a long time but this transient inflation seems to be pretty sticky now can you comment on that? Yeah it's gone from being transitory to being persistent and the transitory story was being promoted by Fed Chair Jerome Powell who said that look when you do year-over-year comparisons and you're comparing prices in March and April this year to March and April last year guess what it's going to show a lot of inflation because prices were depressed in March, April, May, June, July of last year so those year-over-year comparisons are going to be distorted by what he called the base effect but you know once you got into September, October readings you can't you couldn't make that argument anymore and so he switched he pivoted to a new concept which is well it's clearly supply chain disruptions that are causing a more persistent inflation than had been anticipated by him and others earlier in 2021 and now with the pitches well when these supply disruptions get sorted out inflation should moderate and that kind of makes sense the problem is the longer that they persist and create inflationary pressures prices the more that those pressures then get into wages the more that it's a risk of a wage price spiral comparable to what we had in the 1970s I don't think that's where we're going 1970s productivity collapsed I see a tremendous boom in productivity in the years ahead but for the here and now we are having unintended consequence of the Fed's ultra easy monetary policy and the tremendous stimulus provided by the fiscal authorities that was deficit financed all that's created a demand shock which has then created a supply shock which explains why we have an inflation problem right now and it's it's distressing because you know people are seeing their wages going up in their paychecks because workers are in high demand but at the same time a lot of those wage increases are getting offset by price increases when I first interviewed you I spent a couple of years ago we talked about your book fed watching for fun and profit and you came up with the four D's for inflation detente disruption demography and debt so first could you explain those four and then also is there a fifth one now called disease well perhaps in terms of the the four D's starting in the early 1980s until we got to the pandemic environment of seeing inflation making a comeback I was arguing that there were some major structural forces that were keeping a lid on inflation and we're bringing inflation down creating what some people described as disinflation I was I was an early disinflationist I think it was in 1980 I wrote a piece called on the road to disinflation arguing that Paul Volcker probably would break the back of inflation and that we'd see lower inflation not not higher inflation and the four D's detente is the first one it's just I need a word that starts with the D so to explain globalization so globalization occurs during peacetime's markets become more integrated companies and businesses and countries trade more with each other and during peacetime's you get more global competition which is fundamentally disinflationary then in a competitive global economy companies are under a lot of pressure to increase their productivity to offset the competitive advantage of their competitors and so productivity is enhanced through technological disruption so the D is in technological disruption and then there's demography which is a constantly evolving story but the way it's been evolving in recent decades suggests that we're not going to have very much in the way of population growth and meanwhile populations are going to get older more geriatric and that that is inherently disinflationary and finally central banks try to offset all of these disinflationary forces by encouraging people to borrow more so they kept interest rates low they provided very easy monetary policy so we did in fact see a debt accumulation but at some point that becomes a burden on growth rather than a stimulus of growth at some point a lot of consumers have already done their borrowing a lot of home owners have already done their borrowing and trying to encourage people to borrow more just doesn't seem to work and meanwhile if you provide easy credit conditions you may very well create deflation because you may allow marginal companies to stay in business companies that should go out of business but for the fact that they can refinance their debts very cheaply as a result of ultra easy monetary policies I don't know what to do with the disease concept you just introduced because it's not clear how this is all going to play out it certainly looks as though the pandemic has had some impact on contributing to the supply chain disruptions to the extent that port workers have been ill and couldn't work and that certainly could be contributing to inflation rather than disinflation so you know a lot of things changed possibly fundamentally possibly for a while as a result of the pandemic and right now I think we clearly have an inflation problem but looking beyond that I think technological innovation is going to be a source of disruption and is going to lead to more productivity offsetting these inflationary forces you touched on interest rates earlier and interest rates now are persistently low given the high inflation rate you were predicting if I recall that the 10-year treasury should go over 2% probably even getting close to three if I'm not mistaken by maybe next year but it hasn't I mean it's it's been persistently stuck here it seems yeah can you comment on number one what's going on in number two you still have that prediction for next year no I mean I you know I scaled it back it just didn't work out and so I scaled it back to well maybe we'll get the two I thought we get to 2% by the middle of this year and we were going in the right direction there well we got to 1.7% in March and then all of a sudden it started coming back down again for no obvious reason maybe the bond market had more concerns about the underlying pandemic as being fundamentally deflationary and then bond markets really have been globalized so now we've got bond yields at zero or slightly negative in Germany and Japan so maybe they just keep buying our bonds at one and a half percent which is why we haven't gone to to 2% but of course the Fed also has been buying bonds like like mad and I think well but but here there's they've announced them they've started to taper and yet we still don't see the a 2% handle I think we will sometime next year but I don't know that we're going to see 3% I think the Fed is going to be even more liberal next year than they were since the pandemic started continuing to be more concerned about the labor market than inflation and so I think there will be a couple of rate increases next year two not three and that I think the Fed will actually move the goalpost and say that their inflation target is 3% instead of 2% interesting the Fed has been buying a lot of treasury inflation protected securities as well I think they own 20% of the market now yes they do well why are they doing that I don't see any point in it whatsoever I mean the less that the metal in capital markets the better so what what are they doing in the tips market the tips market could actually give us some guidance on what inflationary expectations are doing but you can't come to that conclusion when the Fed's such a heavy player in that marketplace it's it's a mystery I mean other than them believing that they're going to buy bonds they should buy them across the maturity spectrum and as well as in some of the esoteric bonds like the tips but it makes no sense there's no reason for it let's go overseas for a bit and tell me what you see in Europe and then go across the Pacific and tell me what you see in China well Europe has a demographic problem their populations are aging they aren't their populations aren't growing very rapidly they're trying to have policies that are consistent with a nationalistic policies that covering all the region of Europe or at least the the Eurozone and yet they still have a lot of nationalities I mean they still have nation states there that don't necessarily all agree on what policies should actually be and so there's there's a lot of inconsistencies a lot of tensions in the way that system is designed it's they've got a monetary union but they don't have a tax union they don't really have a fiscal union it's only as a result of the pandemic that they started issuing Euro bonds for the region I think Europe got some major issues in terms of stimulating their economy and I don't view it as a particularly vibrant or dynamic economy they don't have the same kind of mix of histories that we have here we certainly have a lot more in healthcare and a lot more in technology and finance than they do there's venture capital here there's a lot of wealthy people that reinvest their monies in new innovations it seems to me as though we're we're more innovative than the Europeans are that's so by comparison to the US I think there's a lot of room for improvement in the way things operate in Europe with regards to China China's got a very very serious fundamental problem also with their demography and they worsened it with the one child policy when we look around the world fertility rates have collapsed below replacement just about everywhere except India and Africa and they'll probably go to below replacement 32 because I think it's all related to urbanization in agricultural communities kids have an economic value in an urban setting kids are all cost and where are you going to put them I mean people live in apartments they live in small houses maybe and so we've seen fertility rates collapse and that's particularly occurred what's occurred around the world it's occurred in China and the Chinese made that much worse with the one child policy which was only lifted in 2015 and now only this year they said okay you could have not just two children but you can have three children but it's too late demographic damage has been done and we can see that in inflation adjusted retail sales real retail sales growth which I monitor every month has launched from about 18 percent in 2011 to zero recently so the demography is really haunting them in terms of consumer demand and then of course their whole property bubble seems to be ready to burst and if it's not going to burst they're going to try to manage to take the air out of it which is going to take a lot of growth out of their economy so they're becoming more and more dependent on exports which is becoming less and less reliable at least exports to countries that they're having political tensions with like the United States like Australia and maybe some others so I think China is operating from a fundamentally weak demographic position and I worry about what that might imply in terms of their military aggressiveness wag the dog right create a diversion yeah let's get into back to the United States and let's talk about an area that you discussed on one of your podcast recently where you're going to begin to focus this whole idea of productivity and where do you see us becoming more productive and you're going to start to focus a lot on that with your research well the the productivity story I think is a huge story I think it's it's the story that will make or break the decade ahead here if this is the 1970s all over again then productivity would will be collapsing during the current decade but that's not what I see I see productivity having bottomed around 0.5% at an annual rate during 2015 now running around 2% which is a significant improvement and I think it's going to go to 4% within the next few years and I think the technology revolution that started in the 1990s is ongoing I think the technologies have become more powerful more user friendly cheaper easier to implement and really lend themselves to being used in just about every business I tell people when you look at your stock portfolio ask yourself if every one of your stocks is the technology stock and they look at me so you you kidding you don't want me to put a hundred percent on my portfolio in tech I said no what I mean by that is you want to own tech for sure but you want to make sure that the companies that you own that are not in tech are using tech to increase their productivity and efficiency so for example these days people talk about fintech and medtech as being sub industries within those sectors and that's the way I'm I'm looking at things the big story really for productivity is the big story in the demography we've got very little growth in the labor force very little growth in the population and that's really the key to understanding why productivity is bound to make a comeback companies I think started to realize before the pandemic that there was something wrong in the labor market there's not enough workers and the unemployment rate got down to three and a half percent before the pandemic and so there's a real shortage of workers pandemic hits then everything is wild for a while and now people have come up with all sorts of explanations of why people haven't been coming back to the labor market but the reality is the underlying demography of senior baby boomers retiring and not being replaced by many by many more younger people but barely by being replaced by younger people we're seeing that the labor force growth is about zero point five percent and the arithmetic of real GDP is very simple it's labor force growth plus productivity growth so if there's no growth in the labor force there's no growth in real GDP unless there's productivity growth and I think companies are going to are already scrambling to use technology to increase their productivity and four percent productivity growth would be it would be marvelous it would be a very bullish scenario I want to one last question it has to do with energy you made comments recently about the potential future rise again of a nuclear power and also cold fusion I just want to touch on those and what would they mean well I'm an economist I'm trainers and economists and my main complaint about economists and the way economists are are educated is if you go back and look at your introductory economics 101 textbook written by Paul Samuelson you'll see that economics is described as the science of optimally allocating scarce resources it's a pretty depressing concept that there's only so much so many resources out there and it's up to economists to come up with systems that optimally allocate those resources and I can fundamentally disagree with that definition of economics I think economics is about technology being used to overcome what appears to be scarce resources the way we know things are scarce is through the price mechanism when prices go up or something well that's there's some there's some scarcity there and then some entrepreneurs as I know I got an idea for how I could overcome that and come up with something better smarter cheaper to deal with that scarcity and it's it's technological innovations that really make the difference and I think that's going to be a big surprise with regards to all these concerns about climate change and about fossil fuels and so on I'm just been fascinated recently there seems to be a breakout of new technologies that may very well allow for the commercialization not of nuclear fission power but nuclear fusion or cold fusion power and if that's the case that would be truly miraculous because fusion generates energy without any emissions it's clean it's it's very very cheap and that may be my next book is trying to map out how something like that would impact the course of our economy and the financial markets and the world absolutely absolutely be a game changer well thank you so much again for being our guest on bogelheads on investing I really enjoyed the talk today and thank you I really enjoyed reading your information I know your your work is for mainly institutional investors but if an individual investor wanted to follow you how would they do that well yeah the reason it's very institutional investors is because we spend a lot of time and money doing given our very best efforts and it's the market that's especially attuned to what we do but individual investors are welcome to at least try it for four weeks go to yardenny.com y a r d e and i.com and at the top of the website there there's a form to fill out a trial other than that I do post quite it quite often almost daily actually on linkedin and then that's shown on twitter as well so I do provide quite a bit of insights that way I kind of view myself as having a day job which is how I feed the family and then having an evening job writing these books and providing some information on linkedin to the general public because I I have learned a lot over the years and I'd like to share it with people and get their opinions and maybe tweak some of my own thoughts at this point in my life I got I got plans for more books well thank you so much again for for being our guest and hope you have a happy holiday you too best everybody this concludes bogelheads on investing episode number 40 join us each month as we have a new guest and talk about a new topic in the meantime visit bogelheads.org and the bogelhead wiki check out the bogelheads new youtube channel bogelheads twitter bogelheads facebook and find out about your local local heads chat and tell others about it thanks for listening


Who said that? The lady at the store That is not a compliment the talk confronts some of these larger Social questions of like why don't I get this same opportunity that this person does some of the Threads that we really wanted to be mindful of it felt like they should all be motivated by some version of love Whether they all had like a different Motivation where like one's like more cautious or one's more mad and one's more celebratory One's more like questioning along with their child It was important for us to kind of hit all the different emotional beats along the way with the stories We really wanted this to go far in terms of Anybody being able to access this conversation. I think it's important for us to have a safe space We didn't want to push anyone away with this story And we more just wanted to create like an open space That felt universal that's like look deep into this aspect of our culture and Now make up your own mind. Don't worry. This is not about you getting a ticket This is about you not coming home talking about some of the lines that were more than what you would see in typical advertising That could potentially be a little bit more inflammatory Like worrying about your son or your daughter coming home Us being mindful of the tone really helped that was like the mother at that point was like just being very concerned for a daughter Like look, this is the reality that I'm actually talking about. This is the perspective And her daughter is like I'm gonna be okay right and it's more of a Question that she gives her mother so I think the execution allows it to Be more digestible so that the line doesn't seem inflammatory It was tailored for Supporting the mothers that were talking to their children in this and in that way I feel like it was successful and then also it's successful in a way of like allowing people to have their own Experience with it whether positive or negative and that's that's ultimately what we wanted. That's why we called it the talk


Hi and welcome to the session. I am Priyanka and I will be helping you with the following question which says, here are two different factor tree for 60. Write the missing numbers. Now this is one of the tree which is given to us in which 60 has been split into two factors that is 6 and 10. As we know 6 multiplied by 10 will give us 60. Similarly, we are given that 6 factors should be 2 multiplied by which number that will make it 6. Between these two numbers there is always a multiplication sign. Similarly, between these two numbers there should be a multiplication sign as well as in this. So we need to fill in this question mark in both the cases. Now let us think about it. We know that when 6 gets multiplied by 10 it will give us 60. So what number we should fill in here which on multiplying by 2 will give us 6. So we will directly divide 6 by this number to get the number which we are looking for. So that comes out to be 3. So the answer to this blank is 3. Whereas similarly over here which number we should multiply by 5 so that the result becomes equal to 10. In the same manner 10 will get divided by 5 so as to get the unknown number and then come out to be 2. So the answer to this is 2. So this completes as it is given to us the factor tree which was given to us. So I hope you enjoyed the session of the first part. Now let us carry on to the second part. Proceeding on with the next factor tree which is given to us. It says fill in 4 of the blanks which are given to us. Right so let us start from the top. Now 30 should get multiplied with which number so that product becomes equal to 60. So we will divide 60 by 30 to get our answer and that comes out to be 2. So the answer to this question mark is 2. Proceeding on with the next one 30 should get divided by 10. So as to find the missing number and that comes out to be 3. So this blank will be filled up by a number that is 3. Proceeding on further now here we need to fill in both these factors. So let us think that which two numbers should get multiplied by each other provided they are prime factors which will give us the answer as 10. We know that in the table of 2 at 5 we get 10. So the answer to this will be 2 and 5. Right because 2 when multiplied by 5 will give us the answer as 10. So this completes the second factor tree which was given to us. I hope you enjoyed the session and found it interesting too. Bye for now.


Good afternoon, and welcome to another episode of a likeable science here on Think Tech Hawaii. I'm your host Ethan Allen. Thanks for joining us today. Likeable science is all about how science is a vital, interesting, and dynamic part of everyone's life, and how we should all embrace science, be excited by science, and enjoy science. And with me today here in the Think Tech studio is Dr. Kate Peralt. Welcome, Kate. Kate is a professor of forensic science and chemistry at Shyamalan University, and has some very interesting things to talk about. Kate studies odors, right? Correct, yeah. And that's an intriguing thing. Before we get into the show, though, I want to do a little plug here for the upcoming Fall SACNAS conference. This is the biggest conference in the world for bringing unrepresented people into science. It's going to be here in Hawaii in the fall, right around Halloween, and the few days thereafter, it's a wonderful event. Everyone should know about it, encourage your students to attend, teachers should attend, faculty, great event. But now, so how did you get interested in studying odors? That's sort of an odd thing to study. Yeah, that's a question that I get asked quite a bit. In my undergraduate, when I was doing my bachelor's degree, I was really interested in forensic science. And to be a forensic scientist, you have to study lots of biology and chemistry. That's something I had a great affinity for from a pretty young age. When I got into my third year, I started a research internship in a laboratory. And at that point, I started working with decomposing remains, where we were looking at odors and other things related to how bodies decompose. And for me, that was it. I could see how biology and chemistry could really be used to help people in the real world. And that was really what sparked my interest. Wonderful. That's very important is that application of science to real world problems. Yeah, definitely. That's one of the things we try to emphasize in this show is that science isn't something that just lives in a laboratory for no reason. It actually has applications. Yeah. So I suspect a lot of people will sort of have an intuitive sense about what odors are, but they're really sort of a special class of things, right? Right. Okay. So it's good that you ask what an odor is. Some people use the words odor and scent or smell interchangeably. And they're not actually the same thing. So a scent or a smell, the way we use those words usually implies that there's a receiver and that there's some sort of interpretation of that odor. Biological receptor of it. Right. Exactly. Like what we have in our nose, right, our olfactory system. When we talk about an odor, though, that's actually a chemical property. So odors are a big mixture of different chemicals that are all combined together. And they kind of give us an odor picture when we smell them. But it's a chemical property and it exists whether or not we actually smell it. Okay. So you can have a machine that can detect an odor profile that we might not smell. Yeah, exactly. Some compounds that are present in odor we might not actually smell. And there might be some compounds that we smell really strongly that are not actually present in that high level. Okay. Excellent. And there's a particular class of these compounds that you talk about some called volatile organic compounds. Why are these sort of what are they why are they important? Right. So volatile organic compounds or we abbreviate them to VOCs, because as scientists, we like abbreviations. And VOCs are basically compounds that have what we call an appreciable vapor pressure. And all that really means in simple terms is that they prefer to be a gas rather than to be a liquid or a solid. So they like to exist in a gaseous state. And when a whole bunch of those chemicals in this gaseous state mixed together, that's what we call an odor. Okay. And being organic, they have to do typically with life forms, there are parts of life forms or exuded from life forms or whatever. So the VOCs are part and parcel of being being alive. Right, they're they're emitted from different sources that source doesn't necessarily have to be alive. Some of the things that we analyze are not living. But they are representation of the volatile part of whatever that target item is. Right. And so a lot of people don't seem to think much about smells except maybe when they smell something awful, right? Like a decomposing body. But obviously, we've built elaborate sensory systems for smell and then smell must have some odors must have some signal value, right? Otherwise, we wouldn't, we wouldn't have these elaborate sensory systems for them, right? Right, exactly. So in the laboratory, if anyone's ever watched CSI or forensic files, you might have heard of an instrument that's called a gas chromatography mass spectrometry or GCMS. This is usually the tool in the show, which is, you know, the thing that gives the magical answer, and it happens in a matter of seconds, and it's really exciting, right? And then that that gives an answer investigatory information. The way that this works to kind of bring it to an analogy, maybe it takes a mixture of things and separates them.  Some people in the group that arrives, they're going to maybe not know anybody and they might be able to cross the room really quickly. Other people might know a lot of people in this party, and they're going to cross the room more slowly. Interact with more people. Interact with more people, exactly. They might have a different affinity for people. We talk about affinity in chemistry. And so the way that our chemicals, when they arrive in our instrument, the way that they have an affinity for the instrument makes the amount of time they spend in it be different. And so they separate. And when we separate things, when they're now in their individual, we can actually then identify what they are and quantify how much of each of them there is. Precisely what chemical this is and how much there is. Yeah, exactly. Excellent. So I guess my question had really been those are on the other end of things. These chemicals are often used for by living things to either to defend themselves, or in some cases to locate food or mates or dangerous things, right? Those are sort of being set of uses probably. There's actually also I guess a general orientation home use. Right. Yeah. So there's really two major things in forensic science that play a major role in the type of odors we analyze from remains or from human bodies. The first are insects. So insects are really good at picking up on these chemical cues and finding for them it's a nutrient source, right? So they're using those VOCs to find a body and they're really, really good at doing that. The other kind of biological sensor that we work with are scent detection canines. And so these canines are able to search for and locate human remains based on the volatiles that are released from them. They can actually orient and they do this really well too. And so we can use that in cases like missing persons or homicides or even in more large scale scenarios like a mass disaster, where we're actually trying to find a body. Okay. So this is this is great stuff. So it sounds like you you do a very interesting spectrum of work that part of your work is sort of out in the field, right? And part of it's in the laboratory, right? And your base at Shamanod's you have a field site nearby, nearby as part of the campus. Right. Yeah, we have a couple of really interesting facilities at Shamanod. This is showing our crime scene house that we have. This is a really great teaching tool. At this area, we can set up different mock crime scenes. And then we also have a decomposition field site as well that we use to decompose pig carcasses.  And we are able to collect volatiles from them. Okay, right, because there are all kinds of interesting ethical issues about using human remains, right? Right, exactly. Right. And logistical issues as well. Yes. And the when you are out in the field, you you need then to capture these odors right to begin your analysis. And I think you have a picture of right. Yeah, okay, so I can describe. So basically, when we have pig carcasses that are decomposing, we place a large stainless steel hood over top of them. So that's this box that you see. It's actually open on the bottom. So it goes over whatever we're collecting odor from that could be a pig carcass, it could be something else, right? Could just be soil that we're interested in. On top of that stainless steel hood, you'll see there's a tube actually kind of sticking out of the top of it. It's about four inches long stainless steel on the inside of that tube is something called a sorbent. The way I usually describe sorbents is kind of like what's inside of a Brita cartridge if you're filtering water. So when you're when you have Brita filter and you're pouring water through it, the water goes through and the chemicals that you're trying to attract stick to that cartridge and the water flows. We do pretty much the same thing, but we pump air through this smaller tube and the volatiles that are in the air then get trapped on the inside of the tube on this sorbent and we can take that tube back to the lab and analyze it. Three or GC amounts. Correct, yeah. So we take the tube to the laboratory, we put it in an attachment that basically heats it under a flow of gas and the heat actually removes all of the volatiles from the sorbent and we can inject it onto our instrument. Yeah, all right. Well, that's great. So that's a really nice sort of spectrum of activities and that you do from very sort of rough and tumble stuff out in the woods to very sophisticated laboratory based analysis. Yeah, I really like that aspect of it because especially with the background that I had in my education, I got to do a lot of field work and I realized science doesn't always happen in the laboratory. You got to get out and do the work in the field sometimes and that's something that I personally really enjoy. Right, that's again something a lot of people don't realize is, you know, in many cases actually a vital part is to, you know, go out there and find that, find those samples that you need that are going to help determine was there a person here, is there a person buried here or whatever. Right. Exactly, exactly. So that's just amazing stuff then. So if we, if we use odors, we smell odors, I mean, does it have biological significance to our lives? In terms of safety, for example, yeah, so there is, we don't do a whole lot of work in this, but there is a lot of environmental monitoring which is done. For example, a lot of building materials give off these VOCs as well and that can have implications in terms of health. If you've ever heard of something called sick building syndrome, that's that has VOC background to it as well. So we can use the same sort of techniques that we have in forensic science. In fact, a lot of those are adopted from the field of environmental monitoring. Okay. And so you've talked in our earlier conversations a little bit about this GCMS machine that you use and it's a very cutting-edge machine. So can you tell us in simple terms what sort of spiffy and cool and neat about it? What does it do better than older machines? Great. Okay. So GCMS is something that's been around for a really long time. It's really a gold standard in most laboratories that you can think of, medical laboratories, environmental laboratories, things like that, forensic science as well. What we actually use, the instrument you see here, is something called comprehensive two-dimensional gas chromatography. So this is kind of like the new age of GC. And what this allows us to do is actually take the compounds and separate them twice, hence the name two-dimensional. So when we could maybe separate, say, 60 compounds in an odor before, now we have the ability to separate maybe 600 compounds. So we pretty much get an order of magnitude increase in what we're able to separate. And that has really important implications because if you can separate more, then you can identify each of these compounds better and quantify them more accurately. Okay. So and this is, again, something I suspect a lot of people don't understand, is that these sort of chemical soup that you're analyzing is incredibly rich in terms of it has hundreds, if not thousands of different chemicals actually within it. Yes. And so the more fine you can pull this all apart, the more accurately you can determine what's really in there, where it came from, how much it came from, what? Yeah, one of the things that I didn't realize when I got into the field is actually how complex of an analytical problem this odor actually is. We have thousands of different chemicals, not all of them might be important, some of them may be important, but we need to separate the ones that are important from the ones that are not. And they also exist in a variety of different chemical classes. So they all have different behaviors. So you're dealing with a really complex analytical problem. You also have some that are really high in abundance and some that are really low in abundance. And analytically that's also a big challenge to get a technique that allows you to quantify things at that different level. So lots of challenges that we're up against and that's why this new technology that we've brought to Shamanad gives us a big advantage in what we do. Excellent. We're going to explore that a little more deeply when we come back. Right now we're going to have to take a brief break. Kate Peralta is here from Shamanad University talking about odors with me. I'm your host Ethan Allen here on Likeable Science and we'll be back in one minute. Hey loha. My name is Andrew Lanning. I'm the host of Security Matters Hawaii airing every Wednesday here on Think Tech Hawaii live from the studios. I'll bring you guests. I'll bring you information about the things in security that matter to keeping you safe, your co-workers safe, your family safe, to keep our community safe. We want to teach you about those things in our industry that you know may be a little outside of your experience. So please join me because security matters. Aloha. Hi my name is Amy Ortega Anderson inviting you to join us every Tuesday here on Pinoy Power Hawaii with Think Tech Hawaii. We come to your home at 12 noon every Tuesday. We invite you to listen, watch for our mission of empowerment. We aim to enrich, enlighten, educate, entertain and we hope to empower. Again, maraming, salamat po, mabuhay, and aloha. And welcome back to likable science here on Think Tech Hawaii. I'm your host Ethan Allen. With me today in the Think Tech studios is Dr. Keith Peralt. Welcome we end Kate. We're talking about odors and Kate's a forensic chemist I guess you call it yourself. And so looks at the chemistry of decaying stuff and that's very interesting because all these decaying things are putting out all kinds of different chemicals but there's a lot of other of these VOCs, volatile organic compounds around too that that are emitted from as you were talking about paints or carpets or building materials but also from explosives right? Most explosives actually emit some relatively low levels of these VOCs so I was reading a while ago about somebody who had figured out that certain wasps can detect these very low levels some of these explosives and they have essentially trained these wasps to make some reaction either wasps fly left or fly right or up or down or something. Some sort of behavioral. Right and so they can build a very simple detector basically just a can with the wasps in it and they run air through it and if the wasps do a certain thing I know that what they've got in front of them is dangerous. Yes. So it's a sort of biological version of your of your GCMS machine right? Right exactly yeah and there's a lot of interest in developing these sort of like handheld tools that can be brought to certain locations critical locations like border crossings airports for example where you can have something that's portable that's easy to use that doesn't require a lot of expertise or training but that provides that kind of yes or no answer. Right. Yeah in that case it's a very specific one these wasps won't particularly react to anything else I don't care if you've got a dead body in there right you know they're not going to care and they're not going to react it's it's very specific sorts of things whether it's your big fancy GCMS can tell you any of these things all of them. Right the the big instrumentation that we use in the laboratories we use to gain information right and that information can then serve to develop cheaper faster easier tools that we can use to detect certain things. Right because it you can then develop sensors that are particularly tuned into some one of those compounds or two or a sweet amount or something yeah and then that becomes more sort of like what what some animals are doing right when they're when they're very tuned into very specific molecules. Yeah. A classic case being the insect sex pheromones right that the males are tuned into this one suite of molecules. Yeah. And can detect them incredibly low concentrations and hone in on them to find their opportunity to make. Right. And there's a lot of interest as well in developing these handheld tools for things like mass disasters where you might have sent detection canines to be able to do some of the work. But those are living beings and they need a rest and there are only so many of them. So if we can develop sensors that can at least help in a complementary manner then that can really alleviate some of the workload in some of those really important cases. Right so this ties in very much then to some of the developments in material science as they're getting better and better at building or molecular building at the molecular level. Right as you as you provide them with analyses of certain kinds of chemicals they can say oh well we could build this neatly trap that and your conformational change or electrical change or whatever. Right exactly we provide the targets for them to be able to then develop those sensors based off of. Yeah excellent excellent that's great and this is I mean people don't I think a lot of people don't realize how important and how driven animals are by these by these particular molecules that the classic case was when I was doing a post doctoral fellowship in Texas we were looking at the sex lives of reptiles and the females put out a sex attractant pheromone as soon as they emerge which if you wipe that off the back of a female you can put it on a paper towel and present that paper towel to the males and they will react to that paper towel as if it's a female snake because it's an attractive female snake they will court it vigorously they will they will chin rub on it they will get on huff and start writhing around trying there to do their best to mate with it even though it bears no relationship other than chemically attractive female it's very very powerful stuff. Right I think that the biology of a lot of these animals and how they react to some of these chemicals is so interesting and I think as chemists it's really our job to try to be as good as they are actually and in some ways we're approaching that but I think using a lot of these animal models and the information we can get from those systems provides us with a lot for our field as well. Right yeah and there's there are a huge array now of studies going on that they've started using sometimes predator scent to help move prey animals keep prey animals out of areas basically where they want the vegetation to regrow or something if they're herbivores and they think that a leopard or whatever is around they won't they won't hang out there they won't eat the plants. Yeah there's a lot of that kind of work also being done with pests as well if you know which chemicals are an attractant or a repellent for a certain pest then you can place those things in different areas to move them where you want them right away from areas where you don't want them. And it's incredibly sophisticated chemistry right I mean right and another classic case that I recall is the there's a spider that produces rather than a regular web a long one long thread with a sticky glob on the bottom of it and the sticky glob puts out actually a moth sex attractant pheromone. Oh okay. Spider has actually learned to produce or learned of all to produce that particular chemical. The only thing the spider eats is male moths of one particular species basically. Wow that's fascinating. But again it's it's taking same kind of idea of picking up picking up odor traces out of an airstream basically. Yep exactly. So yeah this is incredible stuff. So other than those obscure uses of the animals do we've talked about sort of forensic and law enforcement people wanting to know about dead bodies that we mentioned briefly. Border agents wanting to know about explosives. But there's probably a lot more uses that people don't think about right people may want to use these. Yeah that's definitely true there are a lot of different industries that use odor analysis to get information about whatever it is they're analyzing. A good example is the food industry. Odor analysis is used to monitor quality of food products. Meat spoilage for example is a good one that people might not be aware of. So you can use the odor that's coming from a package of meat to see if it's spoiled or not. There's also a lot of work being done with odors to look at food adulteration. So for example if you have some you know really pure extra virgin olive oil that claims to come from a particular region is it adulterated with some canola oil or something like that. So there's a lot of different ways that we can use this type of analysis in other ways that benefit people too. We're actually starting to work on a project here in Hawaii looking at Kava analysis. So we're looking at the aroma that comes from the Kava root and this is a beverage which is consumed in the Pacific Islands. There is a lot of interest in potentially using it as an anti-anxiety treatment as a medicine. And so we're starting to look at the aroma from it so that we can kind of establish a baseline of what that aroma looks like and then use that to be able to monitor you know where these products are coming from and hopefully ensure that there's good quality in them. So yeah you'll be better able to extract what you want from the Kava root and get rid of the stuff you don't want so you can make a more palatable beverage. Sure yeah. This Kava is pretty awful tasting. I don't mind the tasting. But same kind of thing yeah you can see this with for instance coffee you might be able with your analysis to be able to tell is this really cone of coffee as its label is claiming right? Because cone of coffee presumably is chemically different from not cone of coffee. Absolutely it's interesting that you bring that up because last year with my instrumental analysis class that's exactly what we did we analyzed a variety of different coffees some which were 100% Kona or claim at least on the label to be some which were blends of Kona and something else and then some which were completely not Kona coffee. And so we looked at the aroma profiles from those different samples and we try to extract what is associated with the different brands. I mean did you find what anything are people telling the truth? It's hard to really put a blanket statement on it because we analyzed maybe six different coffees and I think you'd have to do a much bigger project than that to say one way or another but there are definitely differences between them and even the Kona coffee itself that we analyzed to pure 100% Kona coffees and they actually look different from one another to chemically so that probably has a lot to do with the specific region there. The land that they're being grown on, the soil how much water they get stuff like that. They call it wine terroir, right? Yeah, terroir, exactly. Yeah, it has to do with the chalkiness of the soil the organic content of the soil, how much rain they've gotten that particular year. Yeah, so we can maybe use aroma to look at the geographical region even. That might be something of interest too, so. That's amazing. So if you had to give some brief advice to students who might want to pursue this kind of area, what advice in 30 seconds or so would you give them? Oh, that's a good one. I think that having a really strong foundation in biology and chemistry is really essential for this field. You have to really have a passion for it. I think communication is really important being able to talk about your science. So having a passion for it really helps you to be able to do that, but find something that interests you that you're never going to get bored by. I feel like with my area of research, I have tons of projects to keep me busy until the end of time and that makes me really happy. Excellent, excellent. Well, this is great and I think that sounded nice. I think it may be a good scientist. You really have to be excited, passionate about what it is you do. So before we wrap up, I want to ask you one completely off-the-wall question now. So, I have a lot of thought to this. If you had the choice of two superpowers, you could either fly or be invisible, which do you choose and why? Oh, that's a good one. Fly or be invisible? I think I'd rather fly because actually we were talking about this earlier that I feel like I haven't seen enough of the world yet and I think there's a lot of really cool science being done all over the world and I think having the ability to fly and really be very mobile and experience science all over would be great. Cool, excellent. Thank you so much. It's been really wonderful to have you here. Kate Perrault from the Shalmanad University of Honolulu as a professor of forensic chemistry and has been studying how things decay and has been here talking with us about odors and I thank you very much. You've enlightened me a great deal and I'm sure in the one you're talking about. And this is what a great conversation. I would say it's been a stinky conversation. But it's great. It's wonderful to learn about this and to hear about what you do. I wish you much success in your studies investigations and perhaps we'll come back later on and talk some more about it. Absolutely, that would be great. Thank you so much for being here. Thank you. And thank you for watching Likeable Science here on Think Tech Hawaii. Until next week, I'm your host Ethan Allen.


Hello and welcome to this video presentation where we will show how to spin a permanent magnet synchronous motor using the Modal Control Software Development Kit. My name is Rosetta Nassio and I'm an applications manager at ST Microelectronics. So, what is the Modal Control Workbench and how does it benefit a designer of Modal Control applications? The Modal Control Workbench is a GUI that is part of the Modal Control Software Development Kit, or SDK. This also includes the FOC library for permanent magnet synchronous motors. The ST Modal Control Workbench provides an easy way to configure Modal Control application software and matching hardware setup. The project generated by the tool is compatible with the STM32 Cubemax for further extension or modification. The Modal Control Workbench supports many of the boards of the Modal Control ecosystem or can also be used with custom boards. It has a large number of example projects to start with. The user can create a new project, input the motor parameters, set the signal conditioning current circuits for current and voltage sensing, and also leverage on an embedded tool for the tuning of the PI controller parameters. This is also an interface that allows you to monitor the application once the motor is spinning. The FOC library includes both sensorless or censored control for speed and position control using all-effect sensors or an encoder. The software reduces the design effort and time needed for application setup. Next is an overview of the hardware setup. We need our laptop with the software that we have just mentioned installed, Modal Control Workbench and STM32 Cubemax. We need a USB cable. We need also a demo board for this specific test. We have selected the STM32-1, which has the STM32-F0 and 6 low-voltage FETs that implement a 3-phase inverter. The topology is the 3-shunt 1 for this specific board. As you can see, the board is a general purpose one. It has a lot of test points, a potentiometer to close the speed feedback loop as well as the connector for the all-effect sensors or the encoder plus three push buttons that can be used to enable or disable the application or reset the microcontroller. The ST-Link is also present on this board, so you don't need an external one. We need to supply this board with a power supply that is capable of delivering 12V and a minimum current of 1A. The motor that we have used for this demonstration is BLDC, low power 4.2W, but capable of reaching 8,000 RPM. It has four power pairs. The oscilloscope is also necessary as well as a current probe that we will use down the road for tuning. For the wiring, you need to connect your power supply cables to J2, be careful the admissible voltage range is 8V to 45V DC. The motor winding phases need to be connected to J3 and the USB cable to J5. On the one hand, on the other hand, any of the available USB ports on your laptop. I have placed the current probe on phase V. The laptop is, as you can see on the right side, running the motor control workbench. This is the basic setup. The motor is shown here. It is a little black cylinder. The board is already supplied as the red LED show. The motor I have used for this demonstration is available on Anheim Automation website if you want to buy one for a few bucks and repeat the test. It has a rated voltage of 12V, a rated speed of 8,000 RPM. The peak current is 2.2A, rated torque is 0.7A per inch, the line-to-line resistance is 3.5A and the line-to-line inductance is 0.7M. The VKMF constant is 0.8V per kiloRPM and this motor has 4 pole pairs. Now I want to go over the workflow that needs to be followed for successfully spinning the motor. First of all, we need to create a new project with the motor control workbench. Then we need to set up the motor control workbench by inputting the motor parameters, setting the current sensing and the deprotection, then working on some drive management settings, such as selecting the proper switching frequency for our application. We need to set the type of speed sensing, startup parameters and the serial communication. Once we have done this, we can generate, compile and download the code into the ST-SPIN32F0. If all of this is done correctly, we can connect the board to the motor control workbench. One thing I want to mention is that if for any reason the motor parameters are not available, you can use the ST motor provider. This is available for download on our website or you can proceed with manual characterization and extraction of these parameters. Now that we have talked about the tools, we can proceed with the generation of the code using the motor control workbench. We start from a new project and we can see from this window that we have the option of selecting either a custom board, both for the control and the power, or one of our, for example, nuclear boards or one of our expansion boards dedicated to motor control applications. The other option is to select a complete inverter board which features both the control and the power stage. Among the featured board you will find the ST-SPIN32F1. We select it and we click on OK. The motor control main page will now load up and will allow us to change and configure the application parameters. The next thing from the motor one, so number of poppers, application speed, denominal current, voltage, value of phase, resistance, inductance and back-emf constant. Then we can move to the current setting parameters and to the speed sensing, where we can select, for example, between sensor FOC or sensor less FOC. Once we are done with this, we can set our protections, bus overvoltage or undervoltage, temperature protection as well as overcurrent protection. And then we can move to the firmware drive management block where we can define the startup parameters for sensor less FOC. Here we have a table with five steps that will allow us to define a current ramp and a speed ramp. From the same block we can also define some drive settings such as PWM switching frequency and the execution rate of our control loop. If all the parameters have been set correctly, we can use this blue arrow to generate the code and with one of the recommended application development environments, for example IR or the STM32 cube IDE, we can flash the program into the STM32 or into the ST speed 32 F0 in our case. Once this is done, we can open the monitor and connect the board by clicking on the plug icon. Ok, if the board is connected, we can now move to the advanced tab and from here we can select the control mode, either speed or torque. If we select the speed mode, we will have to tune the parameters KPNKI for the IQ ID regulator and also for the speed regulator. To do this, there is a whole procedure and we have several tutorials both on our YouTube channel and on our website that I invite you to consult. With the motor connected and with the board connected, we can click on the start icon and the motor will start to ramp up the speed. At this point, we have reached the end of this short video demonstration. For more information, please visit our website.


Hello and welcome to the Grand Line Review, your source for everything one piece. Today, we are going to jot down another entry into the Devil Fruit Encyclopedia by examining the Bommu Bommu No Mi. The Bommu Bommu No Mi is a Paramecia-type fruit that allows its user to make any part of their body explode. It was consumed by Mr. Five and made its debut showcase in the series during the events of Whiskey Peak. This fruit derives its name directly from the Japanese word for Bommu.  As a result of this, most English translations kept it exactly the same and decided to dub it the BOM BOM fruit, except on this occasion for the Vis Manga translation, who chose to label it as the BOOM BOOM fruit, presumably in an effect to mimic the Japanese Onomatopoeia naming scheme that usually comes with Devil Fruits. All right, so we have a pretty damn cool fruit on our hands here as the ability to generate explosions is probably the most destructive fruit we've entered into the encyclopedia thus far. First of all, there really is no condition to creating an explosion, you just can, from anywhere. Hands, feet, nose, colon, you just name it and you can detonate it at will. Unfortunately, there's no real way to measure the exact power of said explosions, but we can say that the power of each individual blast is in direct correlation to how much of the user's body they choose to commit to that particular boom. For example, an explosion generated from the user's hand will be substantially more powerful than one generated from a fingertip, so I guess you could think of the user's body as a source of fuel for explosive techniques, except that it's actually far better than that, because the body of the BOM BOM Onomatopoeia user is a source of infinite fuel. If the user chooses to explode their arm, then well, that happens, and afterwards the arm is still there, ready and willing to detonate once more, because not only does it not get used as fuel, but the user's body also becomes immune to explosive damage, and not just damage generated by the fruit's powers, but explosions in general, which all of a sudden makes this fruit pretty damn amazing. But we're not even stopping there, because the BOM BOM Onomatopoeia provides one other incredible ability, which is the power to turn any bodily generated substance, you know, like mucus, saliva, semen, into explosive material. So, you know, you could spit on someone and have that explode, or even do it Mr. Five does, and flick dried snot into people's general direction at great speeds. In fact, I should point out that even the user's breath counts towards this explosive ability, which is incredibly absurd, but hey, there it is. So what we end up with is a preposterously dangerous close combat fighter, who has the option of using a certain degree of range, which is entirely dependent on how far they can fling their various bodily secretions. Although there are a couple of disadvantages associated with the fruit, first and foremost being that there doesn't seem to be a clear way to increase or even decrease the potency of explosions without using more or less of your bodily material. So while this fruit would work wonders against rookie combatants, it runs the risk of becoming fairly ineffective against stronger opponents due to the fixed damage. I mean, to be fair, a user may be able to increase the strength of their explosions in correlation with their own physical strength, but that is entirely speculation. The second potential weakness of the fruit is that explosions appear to require a conscious activation. So if an opponent were to sneak up on the Bob and Bob Manumi user and smack them in the back, then there would be no defensive explosion.  Still, I think it's worth pointing out that it's a power that consciously needs to be used, meaning that in the hands of a poor user, it's going to be pretty wasted. Speaking of, let's move to Mr. Five himself. He's a pretty competent user of the Bob Manumi, but just as with his partner, Ms. Valentine, he has a habit of overly relying on it. Although he has come up with some very creative uses of the fruit, the most intriguing of which is breathing into empty chambers of a pistol and firing explosive breath bullets. However, I can't help but feel that this fruit was wasted potentially Mr. Five's hands because a guy who can make any part of his body explode out well should not have lost so easily twice, I might add. And in my opinion, Mr. Five's tactic of small controlled explosions was the exact opposite of what this fruit should have been used for. And he should have gone for a more chaotic style somewhat like Gladius from the Don Quixote family. Different devil fruits I know, but for the large majority of the time, Mr. Five chose to only use a tiny fraction of the power granted to him, so in the end, it's no surprise that he was being swiftly. But changing our focus to the area of awakening, I imagine the Bomu-Bomonomi would rather simply result in the user having the ability to explode the environment around them, within a certain radius. So this might be pretty uncreative of me, but I feel like it would have a very similar effect to Gladius' devil fruit, the Pomu-Pomonomi. They accept that it wouldn't require the user of the Bomu-Bomonomi to touch what they intended to blow up.  Some other miscellaneous things to consider when becoming an exploding human. Despite the lack of knowledge concerning the potency of explosions, Mr. Five has said that if he explodes with his full body within point-like range of an opponent, then the ensuing detonation will be so powerful that the victim will be completely eviscerated, bones and all. Partaking in the Bomu-Bomonomi will also provide you with the ability to evaluate explosive material upon consumption. This was seen when Mr. Five commented on how poor quality Usopp's gunpowder was after eating one of his gunpowder star attacks. To conclude, the Bomu-Bomonomi is a particularly power-packed fruit suited quite specifically for combat and demolition. There isn't a huge amount of benefit to everyday existence, and there is real concern in regards to the fixed damage nature of the explosions, but even then that's only a concern when we're thinking in terms of the one-piece world. In reality, this fruit would be ridiculously powerful, with even the tiniest of explosions capable of causing serious damage. So yeah, if that's your jam, then 10 out of 10. Highly recommended. But if you're looking for something a bit more versatile and thus, well, exploding, then I'd say hold off. And with that, we are going to commit the Bomu-Bomonomi to the Devil Fruit Encyclopedia. Next week, we will be examining a very well-known fruit belonging to the Straw Hats archaeologist, Nico Robin, the Hana-Hana-Nomi.
