Hi, and welcome to this week's Wikibon Weekly, presented by theCUBE. Every week, we are combining with theCUBE to present research insights that are relevant and important to our research communities that we serve. And today, we're very, very lucky, because we have Bill Schmarzo, who's at EMC Global Services, CTO of the Big Data Practice, who has willingly taken time away from playing Pokemon Go and being chased around by rat attach. I was told that I'd get a rat attach if I came here, so. Yeah, we'll find one for you some day ago. But to take crucial time to talk about some of the big trends in the computing industry that are being affected by big data, big data analytics, and the evolving practices and experiences and associated with building or deploying big data in business, so Bill, welcome. Thank you, thanks for having me. I'm looking forward to the conversation. It's a hot topic. So Bill, we're going to talk about three separate segments here. The first one that we really want to emphasize is that for 50 years, the information technology industry has operated on what I'll call stylized data. These are data models that are constructed specifically to support accounting applications or HR applications. Nothing wrong with that, very, very successful, but they have allowed us to satisfy legal requirements or other requirements from an operational standpoint. But big data is taking us somewhere different. While we're using analytics to look at that better and look at those operational elements better, big data is taking us into the real world where we don't have access to these stylized data models. We have to find ways to translate analog data into digital data that can, in fact, then be applied to business insights and models to run the business differently. Correct. What do you think is, I mean, how hard is that? As you work with your customers, what are some of the things you're doing to help them envision analog data in digital forms to build these better business insights? So, first off, it's really hard. And the reason why it's really hard has nothing to do with technology. Has everything to do with the culture. And, Peter, you summarized it really well. Stylized data. When organizations stylize data, they, by very virtue of doing that, take value out of the data. They make assumptions about what's important and what's not important, and they leave a lot of the valuable aspects of the data laying on the floor. They cut out sometimes the best parts of it. So, it's a hard cultural challenge for organizations who, for a long time, have thought about data as a cost to be minimized instead of an asset to be utilized. So, there's this cultural aspect of it. And the way we help organizations to start realizing the value of the data is we do something I think is really simple. We help them to figure out what decisions are you trying to make? So, we go through a whole envisioning process about what are your key business initiatives, who are your key business stakeholders, but really boil down to decisions. Because really, at the end of the day, it's all about making better decisions. Decisions about which customers to make, what offers to, which wind turbines, they need, what kind of servicing, what patients need, what kind of treatment. So, if we can focus on the decisions, it's a very simple or simpler way to get the business people to understand the value of the fact that there's value in the data and that if I can apply that data to the analytics to make better decisions, then I've got a way to drive value in the organization. So, in many respects, what we're really doing, Bill, is we're using the decision as a way of circumnavigating or capturing the data elements that will be required to generate the insight that then leads to the activity. Bingo, and the beauty of decisions is that every business user you talk to understands that they're trying to make decisions. It's very natural to them. And by the way, that's very different than questions. People always say, well, what question are you trying to ask and answer? Questions don't imply actions, right? You have all kinds of questions. Decisions imply actions and actions are important. So, we find that when we have a focus around the decisions, then there's two things that fall out of that. There's, number one, is the data itself. What data do I need? What data might be useful? Opens up this whole concept that there's all kinds of different data sources out there that I might want to contemplate that might be more, that might be valuable and help me make better decisions. The other aspect, there's all these analytic models, right? We call analytic profiles, right? The models that help me to support the decisions I'm making that combine with that data to help optimize the decisions and drive analytic lift. So, when we think about this notion of capturing data, ensuring that it is appropriate to the decisions, we're actually successfully, hopefully, putting some bounds and constraints on it. Now, this is somewhat antithetical to what a lot of data scientists think, who just want everything and then they'll figure out what's valuable. By focusing on the decision, we are actually not stylizing it, presuming that we're going to generate greater success in these data than we might in other data. Now, if I focus on the decision, we do two things that organizations do really poor. We focus and we prioritize, right? Because, yeah, you could throw any amount of data you want into a data lake. You could throw all kinds of data, but you'll end up with one of our clients called a Dead Sea.  And so, while we want to embrace the creative thinking process that data scientists normally go through, we also want to focus and prioritize, because not all data's of equal value, especially with respect to trying to drive decisions, and not all data's of equal implementation feasibility. Some data's hard to get, some you have to go out and buy, and so you've got to weigh the value and the cost aspects of each of those data sources vis-a-vis the decision you're trying to drive. So the decision informs the type of data that you need, which then also gives you some visibility into the value of that data in the context of the decision. So you've hit on a really interesting topic here, and organizations are really struggling with this idea of how do I determine value? How do I figure out how valuable my data is? And organizations, when they've used data to report on what happened, really didn't care because the value was minimal, right? You talked about compliance, regulatory reporting, things like that, but now I'm trying to drive decisions. If I can improve my ability to reduce churn by 10%, there's a hard value associated to that. If you're Chipotle and you can increase your same store sales by 7.1% year over year, which by the way is a big struggle for them right now, that's worth $200 million a year. So there are value in the business initiatives and the supporting data, and consequently there's value then in trying to figure out which data sources are most appropriate for helping me to achieve that particular objective. So as you know, we both are business people. We've been in large and small companies, couple of startups, and as executives we always asked ourselves, okay, what financial resources are gonna have to go here? What people am I gonna have to put here? What capital assets am I gonna have to put here? But now you're saying that we need to add to that simple rubric the idea of what data do I need to put here to be successful in this business endeavor. Amen, amen, data's got value, right? You've summarized it many, many times for your talk about data in use has value. And so data is a key aspect of that.  It isn't that they don't know what decision they're trying to make, it's that they come from an environment where data has always been treated as a cost we minimized. You sell to the infrastructure people, right? You approach the storage people and you're talking about data and they're trying to figure out how to drive down costs when the very top of the organization they're trying to solve some hard business problem regarding customer acquisition or predictive maintenance or quality of care, whatever it might be that relies very, very heavily on having the right kind of data at the right level of granularity and the right analytics to help drive that. It's a huge cultural mismatch that we've got to help organizations to sort of address. Now I'm going to ask you a question. We actually think that it's possible to even think in terms of data capital or digital capital, where you have stocks of data that could be in the warehouse but hopefully or in the data lake. Thank you, yes. The Dead Sea. Yeah, not the Dead Sea. The Dead Sea. That could in fact, that if it's properly catalogued, you know what it is, you know how to get it, you know where to find it. You have other sources of data from partners and maybe that you're buying periodically but that ultimately we can actually think about how these stocks of data can be applied to decisions in the form of capital. Is that a concept that your customers are starting to use or at least think about even if they're not using the same term? Yeah, we're actually seeing more and more customers starting to realize and make that flip to realize that data is an asset. I can't put it on the books yet, yet being the key point but I know it's an asset in my ability to drive better decisions and drive monetization efforts. And so we're starting to see more and more organizations starting to realize that the data that I have has got value to it but there's also ability to go out and get third-party data you can buy or even publicly available data. You know tons of it out there that I can start bringing it in and that data when I lay it next to my operational data that I've already have greatly enriches the data I currently have. It takes and adds a whole new dimensions to what I got from a perspective of leveraging the data to help drive those decisions. I want to come back to kind of the original question. The, you know, you and I are having a great conversation, analog. Now we're capturing it on video so we're translating it into a digital format that then can be broadcast out to Wikibon clients and prospects and others. As we think about some of these disciplines for going and gathering that data, how are your clients starting to think about making investments to increasingly take more of that analog data that's so crucial to how business actually gets done and turning it into digital representations so that we can bring it underneath this umbrella of digital capital, big data analytics and some of these new actions. Some of these new insights and decisions. You've hit on a lot of really interesting leading topics there. Obviously, the data has value but what you started talking about there, Peter, was is that the representation of the data in a manner that helps me to make better decisions is a really key point where only a few of our customers are starting to get their heads around the fact that yes, data, so there's, to me there's kind of a multi-step process versus a step that you realize, wow, data's got value because it helps me make better decisions but here's an analogy for you. Data is to analytics as money is to wealth. Having one doesn't guarantee the other and so people are starting to realize that I've got data, I'm starting to collect it, I'm starting to have association value, but if I can't- But where wealth accretes as a consequence of having money, is that what you mean? Yeah, okay. Right, I mean you can have money but not be wealthy. That's right. Right? You can have data not be analytic. The point is to apply your money to activities that then generate a superior return. Exactly, and that's the point I think we're seeing some of our leading customers and realizes that I've got the data and I've got to start building analytics but not one-off analytics. We're starting to see a lot of pretty mature organizations starting to go step back and go, I got a whole floor full of orphaned analytics, one-off analytic projects that I did to solve a particular problem but it's not being reused again. So in the same way that a data lake is a concept that's helping organizations to capture and enrich and mine that data as an asset, organizations start to realize I need to have a framework around my analytics so that I'm not one-off building analytics, I'm building analytics that have reuse, to have the same capital value, right? Digital value that data has. And so we're sort of at the very early stage of the organization realizing that what I'm doing for the data lake regarding data, I need to do something similar around my analytics to avoid this problem of these orphaned analytics. So we mentioned earlier, you mentioned earlier that we know that data has value and increasingly that's being defined in terms of the context of the decision of the work that needs to be performed and that we're not in a position yet to put data on the books or put the value of data on the books. But that doesn't mean we shouldn't stop thinking or conceiving of how we can actually construct an overall framework for capturing, measuring, and ultimately continuously investing in data so that the value of that data goes up. Are you starting to see customers and are you yourself advocating? Because we're starting to. This notion of I don't wanna call it the shadow books but let's call it the data books where data capital gets applied and generates returns that then can be subsequently recaptured and applied to new activities. Yeah, so smart companies don't let the accounting rules dictate how they create value. And so what we're seeing organizations starting to realize that in the big data discussion there are three sources of intellectual capital. Things that have sustainability long-term and by the way, it has an interesting aspect on the technology. Remind me to come back to that. So the three areas of we see organizations and realize there's intellectual capital within the big data conversation are the data. The decisions are use cases which are closer to the decision I'm trying to make. And then the analytic models that I'm building to support that. And we're advocating for our customers that the analytic models, you wanna build the analytic models around your key business entities. We call them sometimes strategic nouns. So think about that might be, if you're a public school, it would be students, teachers, tutors, administrators, classes, courses. There are a finite number of entities that comprise your classrooms would be one, right? That comprise what is your organization. And I wanna learn as much as possible. I wanna gather analytic insights when I understand propensities and tendencies and inclinations and passions and interests and associations and affiliations. And success rates. And success rates, right? For each one of those things. Let me give you a great example. So we had this project for a public school system we did, right? And we created what their teachers called Netflix for teachers, right? Which basically made a bunch of decisions for them regarding how to group students, what students, tutoring, what students need interventions. We even created customized curriculums for every student. In order to do that, you have to know details about every student. You have to build up analytic profile on every student and every teacher. What we found out, by the way, we had some teachers were not doing very good work, right? Their performance levels were really low. And what we found is if you look at the teachers, the problem wasn't the teachers, the problem was the mesh of the teachers with the students with the classes in the subject areas. And when we moved them around, their performance jumped. And so we're starting, very long with an answer to your question, is that organizations are starting to realize there's three sources of intellectual capital long-term, the high-term value. The data, the models. And the decisions. That's it. We call it, by the way, we call this a Rubik's Cube. Because the challenge organizations have is, how do you take this and put it into a Rubik's Cube where all the different sides match up? It's three dimensions. It's three dimensions. It's clever though. Yeah, that's very clever. Don't find a fourth one, please. So let's close this first segment here on this notion of how data, analytic models, or the three assets, data, models, and decisions. Because we're going to pick that theme up in a future Wikibon Weekly. Oh, super. So thank you very much for joining us. Bill Schmarzo, CTO of the Big Data Practices and Global Services at EMC. I'm Peter Burris, broadcasting here from Silicon Valley and Wikibon Weekly, The Cube.


Good morning, everyone. It's been easy your community outreach specialist and today I am back again with the new member orientation Got class awkward English. Hi guys And today they are going to be qualifying for their car buying whatever the heck That is we're gonna find out I know it's different from their safe and they are already sick qualified as of a couple weeks ago But stay tuned. Let's see what we can get into. It's an absolutely beautiful day. I Think it's pretty much like a 70% chance of rain, but uh, it's cold and wet and we're out here to do the thing Months hopefully this will not be the classroom There will be actual chairs and desks and indoor plumbing and everything rather than Our men and women sitting on the floor with the projector on the wall, but you have to start somewhere, right? Also the guy on the right you can see in storefront Okay, everyone so while the guys are inside doing their powerport presentation because the weather is absolutely trash this morning I figured I would just give you guys an update on the four detention guys that we had So they are done with a new member orientation class because when you go to the detention their version of NMO is a lot shorter They are in their own FTO program So when you go on the road, you're in a four month program So you're basically riding with someone and there are different phases that you have to work through to pass to Successfully be on the road on her own. So they have their own version of that It's a bit shorter, but they still go through the same phases and everything like that So I mean if you guys want me to break it down Maybe I'll talk to them once they actually finish their FTO program Because you know their faces so that you guys can get an update of what they've been through and what it's actually like So yeah, stay tuned Everyone I am with Corporal Eric Jones Who is a part of the training unit and assisted with the NMO new member orientation class And he's going to basically break down the powerpoint that the guys did the two powerpoints and what it was about Why was it important? What did they learn this morning? So this morning we did the small units tactics PowerPoint it goes over how to um make room entries and clearing rooms Okay, um That's basically that's literally is it in a nutshell? Yes. I somewhat paid attention.  That's basically yeah, that that was that was great. What else did they learn? Uh, they also did low light tactics using your flashlights when they use when not to use Not to blind a partner not to blind your partner illuminate your partner As they go around so some of it I feel like might have been common sense, but We have to go over everything to ensure that nothing is forgotten common sense is not so common anymore Apparently not 2019 and I don't know sometimes when I'm just But it'll all come together for them tomorrow and friday because that's when they're gonna apply What are they tomorrow? I heard I'm not gonna be out there with them filming, but they are doing a What are they doing tomorrow's basically room clearing Small units working with each other how to move through hallways. Okay How to communicate without talking or or Softly How they enter the rooms not staying in the fatal funnel in the doorways Okay, okay, and then friday is an active shooter I will be out there for all of you and I will show footage from that After the shotgun shoot out friday's gonna be a long day for me. It'll be a long day for you It will I feel like it's always a mark. I I I love these two days Yeah, are these one of your like your favorite days from the nmo class? Pretty much. Yes. Really? I loved oc spray day I I I actually would like this to be like two weeks because there's so much you could teach a student on this That's awesome, but we just don't have the time. Oh, because I was a bit in the suggestion box I would vouch for you. I would be like I vote for that. I don't think baschino would go Oh, but baschino would like that. So yeah, it might be a lot, but that was easy Thank you, and also say hi to all of our followers. This is the first time you've been on here Hello, that's it's a late introduction, but an introduction nonetheless PPE time Personal protective eyewear personal protective earwear You want to make sure it's a good and accurate shot. It shouldn't be pop pop pop. It should be pop pop Make sure it counts. Okay, everyone. I am with deputy trainee wardell Boom, and he is going to give you guys an update on what they've done since last time We saw you. Yeah, we saw you. You were here on our probably our worst day that we've gone through so far I thought it was beautiful. I thought it was absolutely beautiful. I don't know. Maybe you did like I know our followers. They were rooting for you guys. You guys are absolutely great Well, no, I really appreciate it. It's been really good having you out and and being there with us I appreciate you guys joining us. So it's really fun to have you guys out and watching us I love that our followers are committed. Okay. Well, yeah, I know that's what I've seen that's what I've seen So yeah, basically what we've been doing is uh Getting familiar with our agency issued firearms and doing a lot of training We have a lot of guys out here that have vast amounts of experience and knowledge and uh I've you know, I feel really blessed to work for Fasco Sheriff's office Yeah, there we go. And uh, yeah, they just they they've been giving us tons of knowledge when it comes to the firing range and how we should stand Um discretionary, you know, whatever it is and uh, you know, it's it's been it's been a good time Good stuff. So you you've learned something. Yeah, absolutely. Our trainers know what they're doing. Oh, yeah Definitely. Definitely. Yeah, it's I feel blessed to have uh have these guys, uh Has teach us, uh, you know the skills and everything that we need out out there So, I mean I gotta come out here and learn how to shoot like Like once I feel like once I've made in like a hollywood film and I don't need my own stunt double I've made it. Yeah small goals. You need to get out here and shoot, right? I should maybe next time I don't know. She always says that too. She's always Oh, well, maybe next time I'll get sprayed. We need to get her to get pepper spray I'm just like if I keep doing everything that they do I might as well go on the road You might as well. Do we agree? Do we not agree? I mean comment. Definitely I think you'd be great. What do they think? I guarantee they want you out there. What do you guys think? Let us know. Should I keep doing this or should I be on the road? I mean, you could do Tweet-a-longs with me. There we go. Who knows? But thanks for talking to us. Thanks for taking the time. No problem. Thank you guys. Deputy Trainee Wardell.  I can say he's one of my favorites But he might be one of my favorites. I like that. Yeah, but say hello to our youtube family. How we doing everyone? Now okay introduce yourself to the people Tell them how do you how do you become pasco proud? How'd you make it down here? Well, I'm a retired New York City police officer. I did 23 years up in New York. Oh, wow. I know that. When we planned on relocating down to Florida We scoped out west of Chapel area. We liked that area and Where I was in my family, I wanted to check out the law enforcement agency that covers that. Makes sense, you know Actually, I saw you and deputy comac and all your videos and Got me really into the agency. So I investigated. So they're doing something. They're working. Well, it worked for me. I love it got me here and The agency is professional. It's awesome. I love it. Everyone here at the training is unbelievable The firearms instructor amazing. Absolutely. Got me on target. That's what I've heard You're not even the first one that I've heard say that today It might be a trend. I was like all over people. It wasn't for these Our trainers. Yeah, because they're totally aren't off to the side, you know, given any sort of hints or anything like that But I am so glad that you made it down. So guys, I'm just saying move to pasco. It works. Why not? Exactly you get to meet famous people Oh, no. Oh, no That famous word you're just gonna trash But thanks for talking to us and you guys will see more of him in the future We've all done the stick drill we did with the pistol So the starting point will be at the 25 yard line The firing line will be at the 10 yard line. We'll have an instructor on each side back here An instructor on each side up there Uh, muzzle discipline, safeties, all that stuff that we've been practicing for the past three days We're going to fire until all sticks are down. So obviously there's going to be a last place But we're going to fire until it's down. All right, anything on the rules? Everyone understand any questions on the rules? Shoot the stick it's pretty constant I don't guys you guys have to make your guns safe We go to the same question All right, you're hitting safety as you're turning you're going to stop and do said push-up It cost your deep time Safety safety on muzzle discipline turn and go back Everyone good sir. All right with your 130 round mag make your weapons hot Loading make ready. We're not proud of the 14 minutes Okay, everyone. I hope that you enjoyed what you got to see for today's new member orientation class and their carbine shooting and qualification It's been a really interesting day. You got to hear some of the stuff that they were doing beforehand I thought they were moving in the opposite direction if you haven't liked this video already go ahead and do so subscribe Why not at this point? I mean you like the videos you might as well and comment If you thought something was interesting and I will see you guys next time


in nesting, particularly, that he's going to talk about some work he's been doing that will cover both fluid dynamics and humidities. Thank you, Jai. So in preparing for this talk, one of the things that I wanted to do is to communicate what's been fundamental to my research program. If you look at the bottom of this introductory slide, you'll see the northern Gulf of Mexico spanning Louisiana, Mississippi, Alabama, and the Florida Panhandle. And we have worked for the past couple of decades to try to develop techniques that will allow us to describe the coastal region and the flood plain so that we're characterizing with a high level of accuracy, levees, roadways, railroads, any natural impediments to flow and any natural and engineered conduits to flow. And I also thought about my introduction in terms of Jai's retirement. And I note that 40 years ago, he would have found himself at the University of British Columbia, right? And at that time, in 1977, the powers of 10 came up. I don't know if you remember this, but what the powers of 10 does for us is it allows us to appreciate scales. And I hope that it can allow you to appreciate the complexity of adequately describing coastal regions. Now, I'm sure back in 1977, Jai had a few picnics maybe or two, but this is not him. But we go from 10 meter square to 100 meter square. And mind you, this is in 1977. And we can begin to see some of a coastline that we may want to characterize. You may or may not know where this is. We have to zoom out a little bit further. We're at a kilometer. We're now at 10 kilometers. And you may have guessed it by now when we get out to 100 kilometers that we're looking at Lake Michigan in the Chicago region. We're at 1,000 kilometers. And at 10 million meters, we encompass the entire globe. So one of our goals with my research group anyway is we want to be able to describe some very fine features relative to those kind of scales. And we want to have flexibility in our description. So I have some Center for Coastal Resiliency collaborators on the research that I'm going to be presenting today. And most of these folks have been working with me over the last seven years on an ecological effects of sea level rise study in the northern Gulf of Mexico. And we are recently transitioning that into a new study. And I'll provide some description of that later on. But again, the point that I want to make here is that we want to transition from a large scale approach. We want to think about what our resolution is going to allow us to be able to describe and what it is that we're going to have to parameterize or what's at the sub grid scale that we're not going to be able to describe. So if we really want to get down to that level where we're describing this lawn area along Lake Michigan, we have to have a pretty fine resolution. When we began our ecological effects of sea level rise project in the ecological effects of sea level rise in the northern Gulf of Mexico project back in 2010. And in fact, when we were writing a proposal or sketching it out in 2008, we were thinking about what are some of the processes that we want to describe and what is it that we want to accomplish with this project. And at that time, there was very little work that was ongoing that was not in the bathtub modeling. That is, the vast majority of the work was taken in an existing digital elevation model, raising the sea, determining how much of that existing digital elevation model was inundated, and then inferring what the coastal response would be. And this was true with hydrodynamics, this was true with astronomical tide flow, this was true with hurricane storm surge flow. And with this and the following cartoon, what I hope you'll agree with me on is that the coast is rather dynamic. And if we raise the sea level, we're going to have changes at the coast. Now we may be able to do beach nourishment and we may be able to protect the coast, but that's going to get more and more expensive. And if we allow the sea level to rise or if we experience sea level rise and we don't do anything at the shore, then the shoreline is going to be eroded away and the infrastructure is going to become more vulnerable. So these features are these characteristics at the coast, whether they're with a marsh or whether it's with infrastructure along the coast. We wanted to build into our modeling system. Further drive that point home, take a look at the green line, representing the 1848 shoreline of Grand Bay. At that time, there was the Grand Boutour Island. And you'll notice in my talk that I have a little bit of a focus to Grand Bay. I can't present everything that we did in the last seven years, but I can tell a little bit of a story. And in 1848, the Grand Boutour Island still existed. But by present day, it's been completely eroded away. And in fact, by 1960, it had been mostly eroded away. And it's one of the reasons that the Grand Bay Marsh in Mississippi, it has one of the fastest rates of marsh edge erosion of any marsh along the continental United States, because its protection is gone. Because the coast is dynamic and if we want to model historically or into the future, we need to consider that dynamic system. So our process has been one that encompasses not just the modeling, not just field experiments, but also from the very beginning, within the first three months of our project, we engaged stakeholders, coastal resource managers along the northern Gulf of Mexico. And the stakeholders have added a lot to our project, and they've helped to constrain our project to some extent. They've helped us to define global climate change scenarios that we ought to be considering, and those that they considered to be unreasonable for their purposes. Why include a 40 meter rise in sea level, that's going to occur 500 years in the future, if all you're going to do is turn off your stakeholders because of doom and gloom. Let's try to focus a little bit more on the more near term, maybe going out to about the year 2100, and providing them with information that they can consume and that they can build into their adaptive management strategies. We benefited from an enormous wealth of data, as we all do, collected Earth data that's been collected, and it is provided by NOAA and USGS to name just a couple of the federal agencies. We have an integrated suite of models that produce dynamic results that allow us to make these coastal dynamic assessments. And our ultimate hope is that with the involvement of our coastal resource managers, ultimately we're going to have some benefit to the coastal ecosystem and society itself. Our project really is a transdisciplinary research project. It has presented transdisciplinary research outcomes, and a colleague of mine, Denise Goodorm, has written a wonderful paper that is included in a recent special issue we did in Earth's future, and it's all about how we incorporated this into the ecological effects of sea level rise in the northern Gulf of Mexico project. It's not an easy thing to do. This project started with 10 co-PIs. One of them had to be let go along the way. Managing 10 faculty members is always a challenge. Not all of them are really interested in doing interdisciplinary research, but if you stick with it and you work with your strengths, particularly the graduate students, you find that such research can be accomplished and can be very fruitful. So before I get into any of the modeling results, I want to make a point that I hope all of you are able to take with you and to consider and to ponder. Now, we all know how valuable LiDAR has been, especially those of us that do coastal modeling, that do tide and hurricane storm surge modeling. The improvement over the national elevation data sets that we used to have is so dramatic. Going from uncertainties of three to five feet along the coast in the upland areas where upper reaches of the flood plains to an uncertainty that's on the order of a foot is a tremendous improvement. But what happens, I think, is that it's such a tremendous improvement that we get blinded by that improvement and we think that the data is perfect. And like any data, it's not. And so we're trying to develop on the one end a very localized marsh response modeling capability and understand that if we're modeling a marsh and we're doing this over a decade old period, we still only have accretion rates that are on the order of millimeters per year. So if you don't start the marsh surface as closely as possible as to where it's at, you're not going to integrate it forward in time appropriately. And what we demonstrated at the East Point Marsh and at Grand Bay Marsh and at transects all along the coast and what we're beginning to document in Louisiana is that there are unacceptable levels of error in the LIDAR within the marsh systems and we have to devise procedures that we can use to correct that data. Again, that's important if you focus on the lower left graphic, the marsh platform out of which in this case, Spartina Alterna Flora grows is going that that Spartina Alterna Flora can only grow, can only function over a period of time if it's between mean low water and mean high water. If it's below mean low water, then that marsh is going to convert to open water. If it's above mean high water, then that marsh is going to convert to up. It makes perfect sense, right? So what I would suggest to you as just a simple check is if you can run a transect through a marsh that you're interested in studying or if you simply run a transect through the LIDAR that you're going to apply and look at it. Is that LIDAR transect between mean low water and mean high water? If it's not, that's your first indication that the LIDAR DEM has some level of inaccuracy. That's unacceptable for the work that you're doing. In the project we developed hydromem or hydrodynamic marsh equilibrium model. This is a coupling of, in our case, it's an ADCIRC model. It doesn't have to be an ADCIRC model, but that's just what I work with. Coupling of the ADCIRC model with Jim Morris's marsh equilibrium model. With this coupling of the ADCIRC model and the marsh equilibrium model, we're able to estimate biomass productivity and accretion rates for a marsh system. Here's an example in Grand Bay, Mississippi. And so if you look in the upper right of the animated graphic, you'll see the year and the sea level rise for that particular year. We're looking at a two meter sea level rise by the year 2100. Blue of course is water, fluorescent yellow is medium, red is low, and green is high biomass productivity. So as we iterate through time, we're seeing the marsh migrate up one and we're seeing more open water areas created. Now a fundamental part of our project is to put on top of all of this across the three state region, across Mississippi, Alabama, and the Florida Panhandle, Hurricane Storm surge simulation. So we want to simulate what is the surge going to be like in the future? What's it going to be like in 2050 or like in 2100? And if we don't take into account the impact to the marsh system and these massive areas of open water that are created, we're not going to represent the flood plain because we're not going to drive the surge through there like it will now be able to. We're applying hydro mem at numerous places along the Gulf Coast and along the East Coast. One of the more interesting projects that we have right now, we've developed a model that, the hydro mem model that's spanning Chesapeake Bay inlet up to Ocean City, Maryland. So again, the backbone of the work that we do, as Jai said, is the unstructured mesh generation. So for this three state region, Mississippi, Alabama, and the Florida Panhandle, we needed to be able to describe the flood plain up to the 15 meter elevation contour because we wanted to be able to describe Hurricane Storm surge under a sea level rise of two meters. And so we needed to increase the flood plain beyond what it would be today. And we still wanted to have this capacity to describe, as in Grand Bay, the tidal creeks. And so we have this ability to employ the unstructured mesh and have higher resolution out in the Gulf of Mexico and a very finer fine resolution in Grand Bay. The model that I work with, ADSIR, is a finite element model of the shallow water equations. And as such, it is a current condition based model. So the smallest element size over the deepest of the symmetry is going to drive the time step. And when we have a high resolution like this, our time step is on the order of one second. And we'd like to be able to simulate four to six days of Hurricane Storm surge. We'd like to be able to simulate at least 45 days of astronomical tides. We do this with high performance computing capabilities. We provide, or excuse me, we do domain decomposition on a model like this or on a mesh like this and we'll decompose it onto 400 to 600 cores just depending on what we're running. The ADSIRC model frame, ADSIRC plus one model framework is relatively simple. I've talked a little bit about the lower left, the ADSIRC mesh. I've talked about how the coastline is going to change with respect to the marsh. We also need to take into account that if I have a two meter rise, I'm going to have a different barrier island configuration or at least dunes on the barrier island than if I have a 30 centimeter sea level rise by the year 2100. Society will be able to do more beach nourishment if we have less sea level rise. But you know, as an aside, what I like to tell people is think about how expensive that's going to be. Think about the heyday of the United States, post-World War II, all of the infrastructure that we build along the coast, all of the beach nourishment that we've done up until the present day and how much we've invested along the coast when we underwent just a five inch rise in sea level or just a 10 centimeter, excuse me, a 12 centimeter rise in sea level. We've literally best invested hundreds of billions of dollars along the coast just in the northern Gulf of Mexico. What is that going to cost if we have sea level rises that are multiples of that, that are order of magnitudes greater than that? But I digress. And the bottom line here is we need to be able to describe future surface roughness. And with surface roughness, I'm meaning not just Manning's end to describe the roughness of the surface to impede the flow of water, but also the roughness of the surface to impede the transfer of momentum from the wind onto the water surface as it's blowing across the flood plain. We need to have astronomical tides filled into our model. And of course, we need to have a wind field. And the wind field is, in my opinion, just as key as the actual mesh itself. So we employ this in our modeling system. And we have a different configuration for the marshes, for the land use land cover, for the shoreline and the dune morphology, depending on whether I'm dealing with a high sea level rise, present day, low, intermediate low, intermediate high, and again high. And when you see the changes in the colors, when you see a change to a light blue, you're seeing more open water opened up along the coast and more vulnerability to hurricane storm surge. So what I like to think that we have accomplished in contributing to a paradigm shift away from bathtub modeling to coastal dynamics of sea level rise is not just coastal dynamics of sea level rise, but recognizing what is it that drives sea level rise. That's the temperature variation that we have, depending on whether we have a high carbon emission scenario or low carbon emission scenario. So if we have a high carbon emission scenario, we're going to have a higher average temperature, we're going to generate more sea level rise. Now, what our system doesn't take into account, but can, what we haven't modeled as of yet, is what's going to happen if the Antarctic ice cap starts to break up, like we've seen some recent articles in the New York Times about. What's going to happen if we have huge amounts of ice breaking off of its shelf and into the ocean, and we have less than a smooth rise in the sea level, and we are likely to have more of a stair stepping. And I submit that we need to be able to take those kinds of projections into account as well. For the hurricane storm surge for this particular project, we wanted to generate future flood plains, future 100 and 500 year flood plains. And since we worked with FEMA and developed the coastal inundation model for Alabama and the Florida Panhandle, and we had access to the same kind of data from Mississippi, we decided to take a similar approach to our future flood plain assessments. So we down selected from the 295 synthetic storms that were used for the Alabama Florida Panhandle study by looking at the return periods and the surge heights by going back to the joint probability method with optimal sampling, and down selecting only those storms that generated 100 and 500 year flood plains. The result is that we're able to estimate return period still water extents that are a function of the coastal dynamics of sea level rise. Our new project, which we just got underway at the end of last year, we've coined the acronym NGOM plus N2E2, N2E2 because we're incorporating natural and nature-based features along with an economic impact analysis and an ecosystem services valuation. So just as an example, looking in the lower left at the Appalachicola region, we can assess the marsh biomass productivity. We can assess the hurricane storm surge impact and various quantities associated with that. And we can now do this for proposed nature-based features. So maybe it is proposed to do thin layer disposal when dredging is done in this region, do thin layer disposal over the marsh. Maybe it's proposed that we do more nourishment of the dunes and this approach will allow us to be able to assess trade-offs between ecosystem services valuations provided by the marsh and the economic impact that occurs whether the marsh is there or whether the marsh is not there. You'll look or you'll notice again we're focused on these hucks, these hydrologic unit codes. We're doing this over all of these hydrologic unit codes so that someone that's well removed from the coast can begin to appreciate how their tax dollar that's going to support thin layer disposal over the marsh or do nourishment is actually beneficial to them in that they're likely to have less hurricane storm surge with an extreme event. And then we'll also be doing this with nuisance flooding as well. My concluding remarks are relatively simple. One that we all ought to know and that is with respect to the climate we no longer have the luxury of stationarity. I hope in this brief talk I've shown that we can model this dynamic system and we have the basis of a system of systems if I haven't shown that already and we can do this at amazing scales. If you would have asked me back in 1980 if we were going to be able to build a model like this it was inconceivable. Climate change is a generational problem. We can address it but we can't will it away. It's here and we have to work with it. But I think the most important point that I'd like to make is our numerical modeling technology is awesome. It really is. But with respect to climate change the models only serve as advanced diagnostic tools. We're not making predictions about the future. We're providing information for the policymakers to make informed decisions. Few directly related publications that came out of that project and some acknowledgments. Thank you for your time and Jay, thank you for this opportunity to present. So Robert Nichols, I'm just curious about stakeholders because what kind of time scales were they really interested in? You mentioned 2100. In my experience often it's maybe a bit shorter than that and also you mentioned two meters of change. I sometimes find resistance to these large scenarios. I'm interested in sort of take on what they were sort of most interested in. So it's a very insightful question and it really gets to the point and I have to say that my answer disappoints me because the majority of the coastal resource managers that we worked with really what they're interested in is affecting change within their career. And their career span is 10 or 15 years. They've already been at it for 15 or 20 years. They've got 10 or 15 more years left and they want to do something that they can see the results from. And the problems that we face, as I said, are generational. We have to go back to what made us a great nation. I'm sorry I'm not running for office, but it's the truth. My great-great-grandfather didn't come to the United States and cut trees down and pulled the stumps out so that he could be wealthy and have a great life. He did that so that I would have an opportunity to get higher education. I really believe that. He had a generational vision and people back then did and so Robert it's it is the case that they are looking at 10 or 15, but we were able to encourage them to consider 50 and 100 years into the future. And as far as two meters, well forgive me I show the most dramatic, but we looked at low, intermediate, low, intermediate, high and high and the low was a crazy low of 20 centimeters. Just the linear interpolation of the last 150 years onto 2100 the intermediate low is just a modest increase in sea level expansion or an ocean expansion. The intermediate high actually starts to take into account some glacial melt, but very little at that and it is a rise of 1.2 meters and the two meter is just a little bit more of glacial melt. Well a lot more than we have at present because at present the sea level rise that we've seen over the last 150 years is 90, 95 percent of that is just thermal expansion of the seas and if we have two meter rise by the year 2100 then about 80 percent of the contribution is going to come from glacial melt. So I personally think it's still conservative, but the manager of the Apalachicola National Estuarine Research Reserve really doesn't want to show the results to her locals. Sorry if I took a long answer. I was just wondering about the the results you showed for the northern Gulf of Mexico modeling. Did I understand that you're modeling the evolution of the shoreline and the barriers in the dunes or was that? You did, but not me and with a project like this it is really wonderful that you not only have copi eyes but you'll have scientists who if you gain their respect they'll begin to contribute to the project and and two that are of great importance are Rob Dealer and Nathaniel Plant. Rob Dealer is at Woods Hole with USGS and Nathaniel Plant is at St. Pete with the USGS and they developed a Bayesian network approach and that provided reasonable based on historical data. They're Nathaniel and his scientists who used to be my PhD students are working with us on the new project and they're building more numerical modeling into the Bayesian network. Thank you. Okay so thank you Scott very much it was a great talk. So it's poster time and remember what my dad says, vote early, vote often, but remember the vote we're going to only see and have talked about 50% of the posters the other 50% comes tomorrow. So you're voting not


Goodness, I am so late getting this video up, but I did want to share with you what I've been loving in the month of September, and I got a rogue hair here on me somewhere, and I wanted to share with you a lot of new skincare that I've been trying. Now, I want to disclaimer before we get started that this is my job, this is my career, this is what I've chosen to do to make my own business, and I put a lot of time, energy, and funds into trying to find the very best. So if I come on here and one week I'm telling you that something is wonderful, it doesn't necessarily mean that I don't like that thing anymore. It means that there might be something out on the market that I needed to test. We as YouTubers, as beauty influencers, we test a ton of stuff as we go along, and that's why we're always trying to bring you the latest and greatest, less technology changes. And so that's really important for me to say to you today because I have a whole bunch of skincare that I have kind of fallen down a rabbit hole here and found a bunch of really good new Korean skincare that I'm super excited about, but it doesn't mean that my other skincare is not in my regimen anymore. So I'm gonna bring to you in the next month probably my morning and my evening skincare routine so that you can see that. And a couple other things. I also wanted to address that I am going to do an update on my life and everything that's happened to me in the past year, and I know you've all been anxiously waiting for that. I've just had a really lot of anxiety myself trying to get up the courage or the gumption or whatever you wanna call it to actually go ahead and film that video because I'm gonna be pretty vulnerable in it. There's been a lot that's going down. And I apologize for that, but it will be coming very soon. I have a numbering system. As the products go up, you'll see a number come on this screen. And I attach that number to the product and then down in the description box below, I put the link next to it. You can shop that way if you want to. I usually show what I have on for clothing and different things like that. Today I'm going to push that towards the end of the video even though I will be doing a little bit of fashion in between. First I wanna talk about this AHA, BHA, PHA. 30 Days Miracle Toner has all of those acids in it, but it also has 2% Niacinamide, which is brightening. Now what I have found with this, it says non-commod... I can never say that. Non-commodogenic tested skin exfoliating ingredients, dual function cosmetic, low pH toner. Okay, so what I found with this is my skin gets super soft and super hydrated. And it is very, very gently turning my skin over. As I get older and I've gone through menopause now and I just feel like my skin is so sensitive. So I actually stopped using any sort of really heavy duty chemical exfoliant. But this one is so nice that I can use it three days a week in the morning before I start any of my other skincare and it just makes my skin so soft. And I am noticing that beautiful turnover that we want to get rid of our old skin and then push that new pretty skin up to the surface. So really, really enjoying this one. Also, Natrium, that is a company that I've shown you many times that this is a retinaldehyde that they have. Now, I have been using the 0.05% and when I went back to purchase this one, I found the 0.1% which is a double the strength, basically. Now, retinaldehyde is better than retinol because it is one step closer to the conversion process of actually being just vitamin A or Trentinoin like you buy with the prescription. So this is actually better than any retinol that you could use. It does not irritate my skin. I had to stop using Trentinoin a couple of years ago because of the sensitivity of my skin. Now I'm using this and I am in love with it. But this is just a beautiful cream. It sinks in so, so quickly and this is not super expensive. As a matter of fact, it's darn inexpensive compared to a lot of effective retinaldehydes that you find on the market. And then another one that I'm absolutely in love with that I actually use in conjunction with this and you're gonna come after me, but hear me out. If you have been out there looking at all the different retinols and retinaldehydes, a lot of them are pairing vitamin C or ascorbic acid and vitamin E with ferulic acid into their retinols. That's because those are all vitamins and they all work synergistically. Now there will be a lot of people that come on here and say you cannot use vitamin C with retinols. That's not true. They really do boost the efficacy of each other. Now you don't have to use this at night if you don't want to. You can use it in the daytime. That's where most people put their vitamin C serums. I personally put just a little bit in with that retinaldehyde that I've been using. And I just am seeing fantastic results. So I love this one from Nectarium. Again, this is their vitamin C super serum. So it has vitamin C, vitamin A, hyaluronic acid, niacinamide, and salicylic acid. Now what's interesting is it's got acids in it. Have we been told over and over again, don't put retinols with acids in them or vitamin C. It's all too harsh. That's not the case. They boost each other up.  That's what I do. And I do use this vitamin C in the morning as well. But I do put a couple of drops of this in with my retinaldehyde at night. So definitely these are really good products from Nectarium. Especially this vitamin C. I love how loaded it is with good ingredients. I also have another one, actually I have two that I'm so excited to bring to you for underneath your eyes. Have you all heard about snail mucin, the Cosrx snail mucin, that everybody is flipping their lids about? Okay, this one is from Benton. Benton has this, it's called Snail B Ultimate Eye Cream. They have this and they do have an essence as well, like the Cosrx. But it also has BVNM in it. And BVNM along with snail mucin are super hydrators. And so this is what I use after I use a treatment like this. This is Alpha Skin Cares. This is their 15% alpha hydroxy acid.  This works so well as an exfoliator because again, this is super gentle. And you don't want to use this every day obviously. Start with once a week and then build up what is great about it is it does slough that skin very, very gently.  These are great. I've been using them together. And I do feel like my under eyes have just done great things. The other thing you all know that I swear by the Suco Yacca Sujata Eye Cream, that is still in my regimen and that will never go away. I think that is the best hydrator for dry under eyes. I have very, very dry under eyes. My whole eye area is extremely dry. So I have to be really careful and use as much moisture as I can and these products all delivered that moisture, the turnover of the skin and helping the new skin to show through so that the wrinkles don't show through so much. Now, if you've been with me for very long, I talk about the benefits of Bifida. And Bifida is the main ingredient that you can get in Lancome Genifique and Estee Lauder Night Repair. That's why everybody touts that they are so effective and they feel like it's worth the $105, $110 price tag that they put on there. Bifida is a fermentation process. So it's been known in Asian countries as beautiful, effective skin care and they've been using it forever. This one is called May Nyo and it's a Bifida ampule mist. It's barrier intensive skin mist. It says, we begin with our aim to better your life. Now this is very, very loaded with Bifida. It has that ingredient as almost the highest ingredient there. Now, when you get on these and you're looking for ingredient decks, sometimes they have them on Amazon underneath the product but sometimes you have to go to a website. I will try to remember to list that website below. I'm sure one of you will say to me, what is that website? I wanna say it's called Encoder with an I. Anyway, it's something like that. But this is a mist. It's what I love about it. I love that it's a mist. The mist is super fine. So you can wear this on top of your makeup if you want to. As a refresher through the day, it is very refreshing. No fragrance. I have, it has a little bit of a vitamin type smell to it but it doesn't have much about it. They also have this Bifida biome ampule toner which it's boosting and hydrating it says. Now why I'm so excited about this is you see how big this is? We're talking about 16 ounces I think. I don't quote me on that but I think it's close to 14, 16 ounces. And I can use this all over my body and it's not very expensive.  You get that benefit to all over your body. Just think that is so great. So both of these were a yes for me. I also did want to mention this little tool again. I mentioned this in Gadget's video this month and it didn't get great views. So I wanted to make sure I put it in this video too because I love this little guy. This is a little massager for my scalp and it's got the little red light therapy here. It does have massage that's on it inside of the tool itself and then it has these little massager tools which actually it comes with four different ones that you can change out and you can do a facial with it if you want to and also comes with heat. This is the coolest thing. I was really afraid that this little guy was going to get tangled in my hair because I have longer hair, but it doesn't. I've done it a million times to my scalp and no matter what I do unless you're going to really get rough and really get it twisted in your hair it's not going to twist in your hair at all. I love this. It is so calming and relaxing and truly it feels amazing. So I wanted to tell you about that. Again, this is what I'm using for my hair loss that I have had recently and I've had a lot of hair loss recently and I really can see a benefit in getting all these new little cool hairs that are coming up in my scalp. And then also this is the Gua Sha tool that was in that video as well. This is not sponsored. I purchased all of these with my own money this is a Gua Sha tool and this doesn't have the curvature that a regular Gua Sha does but it does have a little bit of a curvature and this one has heat. It has a little red light therapy in here and it does have massage as well and then you can do your Gua Sha with it. I love that it has all three. Now do I think this is the best red light therapy? No, but I love that it has the heat and I also love that it has the massage because it's bringing all of that blood to the surface which is what the hair tool does as well.  So I really do enjoy having that one and I wanted to mention it again. I'm gonna try and be very consistent about it and I know for a fact with Gua Sha you're going to see a big difference in your life.  This is a hobo bag that is kind of a dusty rose color. I got this last year but I remembered it and I brought it out because I think it's a great transitional piece to have going forward into fall. Now one thing is that this baby is big. It's a really big purse and I have been kind of trying to get away from huge purses like this but if I continue to remind myself not to overload it then I'm just fine with it. I love the black piping detail that they have on here and then all of the zippers and the buckles they are all done in gunmetal and I think that's so pretty. This comes in a ton of color.  This is one of my favorite bags and got carried over which is a big deal for me because I'm a purse lover and so I like to give them away to my family but this is one that I kept just for me. Two products for the hair again, not just the tool but this is for the hair. So IGK and ColorWow have all of a sudden become my favorite to hair care lines and they're not cheap I know but I'm not somebody that uses a ton of hair products. I usually have my hair pulled up in a bun because I'm always sweating with menopause. So this one right here is called Antisocial. The reason that I was so intrigued by this is this is a spray can that is like the bonding conditioner that Olaplex has that everybody's going gaga for. Great product by the way. However, if you've seen any of my dupe videos you know that L'Oreal has a dupe for it which I'll put down below for you as well.  By the way, the smell in this is divine but yes, if you're bothered by fragrance you're not gonna like this. I love this fragrance, it's really good. So this is Time Release Bond Building Dry Mask. You can wear this anytime. Now I would say that if you're like me and your hair is pretty fine, don't go hog wild on this and be conservative but you can spray this every day on your hair. I wash my hair like every third day. I never wash it every other day so it's usually every third day and I put this on every single day, starting at day one. So I really do love this. I think it is really helping my hair be repaired from all the damage and all the fallout and yeah, I'm really enjoying having that and I got this one, this can is almost gone and I think I got this probably seven months ago, maybe eight months ago, so this lasts a long time. And then also from IGK, this is their new one. This is the Pick Me Up. This is the Maximum Lift Root Boost Spray. Now you can use this wet or dry. However, if you put it on dry, it's gonna make your hair a little bit wet and you're gonna need to use a blow dryer or something in there. It's got a directed nozzle. Hopefully you'll be able to see that. So it's going to go right at the scalp.  And you know, again, you don't wanna put too much on because too much of a good thing can be a bad thing if you have fine hair. But as far as this being a root lifter and giving you really good volume, for me it's fantastic. So I will spray this all over my head when my hair is almost completely dry. Like it's still got a little bit of dampness to it.  You will immediately see that root lift and it's beautiful and it lasts me at least 24 hours. If I'm sweating menopause, that whole entire hot flush situation, obviously, my hair's not going to have a lot of volume and a lot of body, you've been through it, you know what I'm talking about. But it is a really good product to help boost that as much as possible. I also wanted to share with you, I have every single time I'm on camera, I wear these readers. And these readers come in a pack of four, they have bling right here and then they have a little design right here. They're very feminine and I love these. And they last like crazy. I mean, I can have a pair of these for over a year. Sometimes, you know, if I sit on one or step on one, be in a goober. And that's my bad and it's not the glasses themselves. I love these. I think they're so cute, they're stylish. They come in different colors.  I can't remember exactly, but I'll make sure I link them down below for you because each time I do get asked where I do get my readers and yeah, they're off of Amazon. Somewhere about two months back, maybe, maybe not that long. All of a sudden there was this glut on the market of all kinds of mascaras. And I did briefly talk about the Benefit FanFest mascara that it did not work for me in that it flaked. But this one from KVD Beauty is gorgeous. And this one is called Full Sleeve. I love this mascara. I have worn it and worn it and it does not flake. It's got a nice shape to its wand right there and it is a silicone bristle brush. I would much rather it be natural bristles, which I've changed over very recently. Those of you that have been with me a long time, you know that I've never been a fan of natural bristles. I've always loved silicone, but I'm finding as my eyelashes are a little bit more sparse going down the road here that I needed that natural bristle to make them fan out and catch every single one. But this one does a really good job. It is what I have on today. And I really have been in love with it. No flaking, yay. No smudging, yay. And so that one has been great for me. I'm trying the new Anastasia one too. So I'll let you know about that. And then this one, I'm not sure if I've shown this one to you all or not in the past, but this is the new Falsi Serial. This is their new mascara from Maybelline. Doesn't it seem like Maybelline and L'Oreal, they come out with a new mascara like every 10 days or something? This one is a natural bristle brush. This one is the waterproof formula. I love the way that this builds up. I wish that I had not bought the waterproof formula. I wish that I just brought the regular. So the next two of this, and yes, I am repurchasing this, no doubt because I love the way this builds and volumizes my eyelashes. They just look beautiful, almost like a Falsi on. And I definitely can recommend this one as far as the waterproof goes. It's really good. It wasn't terribly hard to get off, but you know, Maybelline has that little pink tube that we wore when we were in the 80s of the waterproof mascara. And boy, howdy, you put that on and you were getting that stuff off for like weeks. And this is not that bad as far as the waterproof goes. But I do want to try the one that is the washable so that I can report back to you on whether or not it is a really good one or not. But this one, I've been in love with and I've worn it until I'm ready to get a new tube of it. So let's talk about this. I was so excited to find these. I have been talking about Foundation McSins for years. As a matter of fact, down below, I will list my video, my very first video where I talked about that. Had to been at least four years ago. It was LA Girls products and they are fantastic. They're a matte product. You need such a teeny tiny amount because they're super concentrated.   Well, because for me, being the cool gal that I am and that I'm very pale, foundations are almost always too orange, too red, or they are not light enough. So this is what you do. You buy either color of these. Let me tell you what they are before taking my glasses off. It's called D-Roll, D-E-R-O-L. And they are Art Gallery's Foundation Mixers. I have a blue and I have a white. And the reason that I'm sharing these with you instead of the LA Girl, I still love the LA Girl and I still use them, but these are a thinner formula. And they still have that nice pigment to them, but they are a thinner formula. I have been using these quite often and I do love them. What's great about them, look right there. You can see how much that just lightened in my hand, how much my hand looks so much different on that side. It's amazing to me that how much pigment comes out of these in such a small amount. And that's great too, because then you don't have to buy them over and over again. And I like this blue one specifically because it isn't as thick as the LA Girl one. And so as you're mixing it, you can't overdo it. Sometimes when I get into the LA Girl one, if I put too much in there, I'm gonna all of a sudden have a mess because then it's gonna be like, I don't know, like purple foundation that I've mixed with a foundation that's too pink or too red. I do love this. They're great consistencies. And I think that if you've been wanting to experiment, they're not that much money. And so go ahead and try them and experiment with them. They do have a yellow. If you're somebody that can never get your foundation to be warm enough for you, I think they have a yellow that you can put into. So this is a great investment and you don't have to throw away that 30 or $40 tube or bottle of foundation just because it wasn't the right color for you. These are great. Also, doesn't this look like makeup forever? I found this palette of blushes. Sometimes when you get these, they're not the quality of the higher brand. Well, I have found that these are the quality and these are so good. I really love these. I think they have great pigmentation and they last. They're cream, all of these colors are cream. Isn't that great? And so you're able to mix whatever you want to in here. You have some very earthy tones in here as well, but you have those pretty pinks and you have those pretty corals. And my goodness, you get a ton, like 12 blushes, 12 different blush colors in here. And yeah, I've really been enjoying this. I also found, now keep in mind that I did a video earlier this year where I was talking about the fact that I'm a blush junkie. I am so bad. So I also found these blushes. Now, Juvia's Place came out with blushes that are in this form, this doe foot applicator form. But when you look at those, I'm getting blush everywhere. When you look at those, they're $18. I think these might have been 10. They might not even have been that much. Where am I gonna put this? Let's put them up here. So this is a bubblegum pink color. I'll make sure I list all of these below for you. It's hard for me to put my glasses on and off when I'm trying to swatch. And then this one is their coral color or they're actually true pink color. And then this one is a bright, bright pink color. These are all so pretty and they are so pigmented. Yesterday, I used, I think I used this one that's the true pink that I was talking about. And I put like a dab on, like that much right there. And then I used my brush and that's all I needed. And it was so pigmented that I actually had to go back in with the brush I was using for my foundation, kind of make it a little bit more subdued. But these are good, good blushes with a great formula and a great lasting power. And they have a bunch of colors in these as well. So if you're somebody that really likes that liquid formula right before it goes to cream, because this is a little bit thicker of a liquid formula, it's even a little bit thicker than the ones for mirror beauty, I feel like. And I know that they're thicker than the ones from Juvia's place. So they have more pigmentation. In my opinion, they do. So love these so, so much. Also this month, I found one of these really cool gadget things. So you have your very unassuming looking Q-tip, right? And you have a line right here. Hopefully you're gonna be able to see that. You have a line right there. You take that Q-tip and you just pop it, okay? What happens is the liquid that is in the tube goes down into the other part of the Q-tip and guess what you get to do then?   It is just fantastic. I love these little things. Look at that. It's so cool. So you have built in little, like my Seller Water in there. It feels like that. Very light. It's not gonna drip or anything like that. It all definitely goes right into that tip. Yeah, I was like, where have I been? My head in the sand or something. Love these things. I also wanted to show you a lovely rediscovered lipstick and I knew I was gonna have people ask me, what lipstick do you have on? This is from Rimmel and I've not been able to find Rimmel at my Walmart anymore, which makes me very sad. But this one is called Soft Hearted and it's so, so pretty. I think that this is one of the prettiest ones that they've ever made. Their lipsticks for me are on par with Revlon and Maybelline. I think they're some of the best lipsticks on the market. This one is not too matte, but it's not too creamy. It's that perfect sweet spot in there where it's gonna still show up on your lips and still give you a lot of hydration without being too slippery and it's gonna come off immediately. I just, yeah, this is great. Really, really, really great. And I want to go ahead and get a few more of these. The ones that I used to get are the ones that had the Kate on them and they had all different colors and whatnot. And I love those colors, but they don't have those anymore, but they do have some that I've used for years and was able to repurchase and definitely wanted to bring that to you because I know everybody was gonna go, ooh, you have dark lipstick on today so I wanted to make sure I showed it to you. All right, let's take a minute and I will show you the outfit of the day. Okay, so you've been seeing the top all the way through the video. This has got lace sleeves and it has kind of a double ruffle on it, really cute. And then it does come down and skim right at the hip line. This is really cute tucked in or have it out. You could wear this with a skirt because it's a little bit more dressy and you can wear it with jeans just to dress it down a little bit. I really love this. And then these are just a pair of my favorite jeans that are skinny jeans. I wear skinny jeans. Everybody is like, no, you can't wear skinny jeans anymore. I am probably going to wear skinny jeans till the day I die, either that or pair of leggings I'm gonna be in. But I love that these are so stretchy around the waist and they're stretchy all the way through the whole jean. And I would tell you that you might want to size down unless you're really a lot bigger through the belly, you might wanna size down because I think I did size down, I'm usually a 12 and these were 10s, which is a nice feeling but that wasn't done because I actually fit in a 12.  And I've washed and dried these a million times and I just love them. And they are, you know, they've got cute back pockets and then they've got the pockets up here in the front. So they are a five pocket jean. And yeah, I just really think they're fun and cute and they go with just about everything because of the wash that they are. Okay, let's take a peek at this jewelry. This is a gold chain that has some little rhinestones in here with a silver look to it right through here. And I just like the way that it lays. I've always loved this necklace. I wear it over and over again on camera. And then I also have a pair of new earrings which are really cute because they have this front little swirl, gold swirl right here that attaches but the jacket on the back of it is little crystal on the end with a chain. So you have the front part of the earring and then you have the back part as well. If you were wondering how those were attaching as I was talking today, that is them. So that is the end of the video. Thank you guys so much for being here with me today. I do love having you. If you're new to my channel, I would love it if you take a second to smash that subscribe button. That helps me so much. And we would love to have you here as a part of our YouTube family. It's exciting for me to have new people here but also I want to take a second and tell my longtime subscribers how much I love you and I do appreciate you.  And please know that when you start telling me about your lives as well, my concern for you is real. I think that comes with age, don't you? We want to see each other succeed and we want to see each other do great things. Just women building other women up and I think that's fantastic for us all to remember. So thanks guys for being with me. Please tell me what you thought about all of these fun products or if you tried anything last month that you just fell in love with. I'd love to hear that from you too. I hope you come around in my next video and we'll be together very soon. Love you much. Bye bye.


So remember the symbol nth root of a refers to the principal nth root of a If it exists this number will either be non-negative if n is even or The same sign as a if n is odd It's easy to determine whether a number is positive or negative But if the radicand is a variable expression, we must be more careful and use the absolute value Remember the symbol absolute value of a indicates a non-negative number whose magnitude is the same as a So for example, let's say we want to simplify the square root of a squared Since a squared is a squared then a is a square root of a squared And we might write square root of a squared equals a But we would be wrong In order for this to be the square root of a squared using our radical symbol It must also be non-negative because remember square root of n using our symbol is the non-negative Number whose square is n and we don't know whether a is positive or negative So to guarantee we actually have a non-negative number. We'll use the absolute value It's important to understand that we're not using the absolute value because we have a root We're using the absolute value because for square roots. We have to have a non-negative number So if I want to simplify the cube root of x cubed since x cubed is x cubed then x is a cube root of x cubed And we can write the cube root of x cubed is equal to x Do we need absolute value here? Well, remember if x is a real number that x cubed will have the same sign as x and Since we're dealing with a principal cube root. We need to have the principal cube root have the same sign as what we started with And so x and x cubed have the same sign and we don't need to do anything In fact, we can go a little bit further since absolute value of x is always Non-negative, but might have a different sign from x to the n It is not generally correct to write nth root of x to the n is the absolute value of x Instead we must consider whether the root must be positive If n is even then the nth root of a must be non-negative So the nth root of x to the n is the absolute value of x But if n is odd then the nth root of a must have the same sign as a So the nth root of x to the n will just be x with no absolute value In other words, you have to use the absolute value for even index roots And you can't use the absolute value for odd index roots For example, let's try to simplify square root 50 y to power 6 We can begin by factoring by perfect squares So remember that as long as a and b are non-negative, the square root of ab is the square root of a times the square root of b It's also useful to remember that c squared is non-negative for any real numbers c So y squared y squared and y squared are all positive And so we can break apart this square root into a product of the individual factors Square root of 25 is 5 Square root of y squared is the absolute value of y Square root of 2 is just square root of 2 And we can combine these three absolute values of y into a single absolute value of y to the third We can find the fourth root of x to the 10th y to the 6th And we can simplify by factoring out perfect fourth powers We can break up our radical into a product of radicals The fourth root of a fourth power is x or y But since our index is even we have to use the absolute value And we'll rewrite this as absolute value of x squared y times the leftovers Or we could take the cube root of 8x to the fifth. We can remove perfect cube factors We can break our radical into a product of radicals The cube root of 8 is 2 and the cube root of x cubed is x And remember if the index of the root is odd, don't use absolute value And finally we have the leftover bit cube root of x squared How about a quotient? So it's useful to remember for a and b non-negative The square root of a over b is the square root of a over the square root of b And so that means we can split this square root of 50 y to the fifth over 18x to the third As the square root of 50 y to the fifth over the square root of 18x to the third Now if you listen carefully to what I just said, you'll realize there's a bit of a problem We don't actually know whether 50 y to the fifth or 18x to the third are positive So we might not be able to do this And if you're concerned about this, you should be But we'll see how we can resolve this once we get to the end of the problem We'll simplify the numerator We'll factor the radicand by perfect squares The square roots of 25 y squared and y squared are going to be 5 The absolute value of y and the absolute value of y And we have our leftover square root of 2 y The absolute value of y absolute value of y can be multiplied to be the absolute value of y squared And remember c squared is non-negative for any real number So we don't really need the absolute value in this case Meanwhile, we can also simplify the denominator. So we'll factor 18x to the third by perfect squares This breaks up as a square root of 9, square root of x squared, square root of 2x and we can simplify And we get our denominator And here's an important idea. We should answer questions in the same language. They were asked In this case, the original question was the square root of a quotient But as written the answer is a quotient of square roots So what we should do is to recombine this quotient of square roots and rewrite it as a square root of a quotient And here's the important idea. Remember that we had some concerns about being able to split our square root of a quotient into a quotient of square roots because we didn't know if the radicand was positive or negative But if the original expression has any meaning Then the original radicand has to be non-negative, which means that x and y have to have the same sign Now it's possible that they're both negative But in the final simplified form as long as they have the same sign the radicand will still be non-negative
