A mystic, yogi, visionary, humanitarian, author and poet. Sadguru is a spiritual master with a difference. Traversing seamlessly from the ancient to the ultramodern, he bridges the gap between the known and unknown, enabling all those who encounter him to explore and experience the deepest dimensions of life. Making a clear break from the mere customs and the rituals, Sadguru presents the inner dimension in a scientific manner, as it is relevant for our times. Through the mystic art shows Sadguru in his various facets in conversation with eminent personalities from various walks of life. Exploring a vast array of topics including business, politics, design, architecture, sports and ecology. This week's episode features Anupam Kher, Padmishri Award-winning actor and social activist in conversation with Sadguru. Noted for his versatility, Anupam Kher has played just about every kind of role in the course of over 400 films and 100 plays. He's also the founder of the Anupam Kher Foundation, which aims to create a brighter future for children from less privileged backgrounds. Watch as Mr. Kher and Sadguru discuss various aspects, including the state of India's democracy, the power of attention and the children of today, losing their sense of wonder to the W-W-W. I feel very proud to be an Indian and I'm sure a lot of people feel. But corruption bothers me and I'm sure you also spoke about it. How… do you think spirituality can help get rid of corruption to some extent? So let's understand this corruption because it's a very important thing that everybody understands this properly in its right perspective rather than reacting against a bunch of people who are in an advantageous position. Why I want you to understand this is because for the first time in the history of independent India, the sixty-four years, that means two generations of people, they have at least fifty to sixty percent of them have had such a bad deal. Today you and me will talk all this and go home and eat well. There's a whole bunch of people, almost four hundred million people who cannot do that. So if we handle the next five to ten years' right, we can change that. It's a tremendous possibility which is on our threshold. There's an economic possibility sitting on the threshold. If we conduct this right, we can change their lives. Those people who have not eaten properly, those children who are malnourished which have the highest level of malnourishment, those who are not educated, those who don't have opportunities, those who are in that horrible social and economic pit, their lives can change in the next five to ten years if we conduct our act right. Every Indian should understand this. It is not just about economy means stock market. It is about hungry people who will have food on their plate. Economy does not mean stock market. Economy does not mean foreign cars coming into India. Economy does not mean you wear better clothes or this and that. Improving economy means there will be no hungry children in the country, which is something all of us should do something about. And that possibility, that possibility is being jeopardized. Wherever I go, I speak to various economic and political leaders around the world. Everybody says, we want to come to India. India is a big possibility but the humiliation of corruption, we can't bear it. Because it's not just about money, they're willing to pay a percentage and get the work done but the humiliation that they put through on a daily basis, which we have gotten used to. They're not willing to go through that. They said it doesn't matter if we don't do business, but we don't want to come there and go through all that rubbish. So this possibility is being jeopardized by a handful of people or it is wrong to say it's a handful of people.  Correct. Because how many people in Mumbai streets, if there is no policemen will start at the red, stop at the red light, I think only ten percent will stop. So these ninety percent are corrupt people. If they make, if you make them the chief ministers and prime ministers, you know what they will do. So instead of just calling it by one bad word called corruption, we need to understand we as a society are trying to move from a feudalistic way of managing our lives to a democratic way. The democratic way has still not sunk into us. So I am saying in our psyche we are still feudalistic in nature, but we are trying to run a democracy. Democracy will not happen with an active sense of education as to what is democracy, what is the power of democracy, what it means, what is the responsibility of living in a democratic society. This has not been done. We just took democracy from the British and we think if they just put their oat and get their fingers dirty once in five years, everything is settled. No, we have not educated people. We are still a feudalistic society acting to be democratic. So how do we, how do we do that? No, no, no. It is only because common people are not participating in the democratic process. Participating in the democratic process does not just mean once in five years you cast your oat. Most people don't even do that. But I am saying even if you do that, that is not enough. Democracy is a, is an active sport. It's not a spectator sport. You can't sit back and say, let somebody do democracy. Democracy means you are the boss. You can't sleep on it. You have to be active to everything around you. If you do not bring that consciousness in people, that awareness and activism in people, it will not work. At the same time for everything you protest, for everything you call a band, it's our culture. People have understood the technology of how to stop the nation. But how to run the nation, it's a different technology. I am saying, at least once a month in your street, in your region, whatever is the sticking points in your area, in your street, just make a list of that. Get a few people together, whoever the councillor, the MLA, call him for a meeting, once in five years is not good enough. Because you employ somebody and you don't see that he works. That is not... That makes sense, isn't it? Do you get angry? You want me to write now? It's not that I'm incapable of anger, I'm capable of everything. It is just that I have not given this privilege to anybody that they can make me angry, they can make me happy, they can make me unhappy, they can make me miserable. I have not given this privilege to anybody. If... if somebody need to be shouted at, boom, I'll go. So what makes you angry? It doesn't make me angry. If they need a shouting, I'll give it to them. See the different kinds of people in the world. There is somebody here, if I just look at them, they'll understand why they're being looked at. There's somebody else here, if you tell them gently, they will understand. There is somebody here, if you tell them gently, they won't get it, you have to shout at them. There's somebody else here, even if you shout, they won't get it, you have to knock them on the head and tell them.  I am not bound like this, I will not say this, I will be gentle, I will be nice, I have no such things. I am just appropriate to the situations that I do. What's my problem? What's your shortcoming? My shortcoming is, I'm not tall enough.  We know that. I came little short. Do you feel lonely? Lonely? When you're alone, if you feel lonely, obviously you're in bad company. It's a great journey to be talking to you. If you have to describe yourself in one word, what will that word be? So if Sadhguru has to decide, and if he has to tell me to describe himself in one word, one that missed, apart from mystic. Okay. Would you consider wildlife as two words or one word? What is the word? Wildlife. It's, for you it's one word. One word. So life, life uncultured, uncultivated, just wild and as it is. Touch me. You're very warm also. Just life, nothing else. It's been very enriching talking to you, I must say that I feel it. I grew up in a lower middle class family, small town. As a child I had a great sense of wonder about everything. I till today have a great sense of wonder. I'm very happy to be talking to you. I don't see that in today's children. I don't see a sense of wonder in today's children. I think because they're Because they replace the wonder with www. Exactly. Exactly. That's right. They know the whole universe before they're six. Exactly. How do, and I'm sure parents, they know everything. They just have to press Google and all the information, but information does not necessarily translate into knowledge at all. So how do, and they always say this, that's the way I am. I don't see my grandfather even at the age of 84 said, that's the way I am. So what is this, that's the way I am. God, dude, cool. I think that to be bad is being cool. If you say I'm a good man, he's a boring man. Usually they are. People who claim that they're good people, usually they are boring. Yeah, they are for the world, for the marketing part of it. We are becoming people who are constantly made to fail, suddenly in India also that we are living in a world which is not very, very peaceful, which is not to be, which is a dangerous world. We are becoming, pardon my saying, like America, where we don't look at somebody for a little longer. I was in America two years back. I was looking at somebody thinking whether should I ask him my hotel, because in my hotel there was a mall. So I went into the mall and when I came out I could not see my hotel because I must have got out from somewhere else. So I was looking at somebody to ask him whether should I ask him where my hotel is. So he said, what are you staring at? I being an actor I said, am I staring at you sir? I'm sorry, I did not know I was staring at you. Poor fellow actually dropped me to my hotel. What my point is, how do you retain, how does one in today's time, in these times retain a certain amount of innocence, a certain amount of sense of wonder, how does one do that? See now there are two things you said, wonder and innocence. Wonder does not necessarily come from innocence. Okay. See for example, when you were a child, you definitely looked up at the sky, isn't it? Absolutely. Did you ever count the stars? I used to do that in similar to nothing to do. How far did you go? Oh no, no, nothing. I could not go beyond hundred or two hundred.  But today that itself was wonder, seventeen hundred just blew my mind. Today scientists are telling you there are over hundred billion galaxies, not stars, hundred billion galaxies. So as you explore, as you know the wonder will increase because you realize the nature of the existence, then wonder will just explode.  Nobody is, today people are carrying their attention deficiency like a qualification. See existence will yield to you only if you pay attention to something. Anything in this existence will yield to you only if you pay substantial attention to it. But now people have become like this. They can't look at anything, everything is chuck, chuck, chuck, chuck. Now in this condition there will be no wonder only conclusions in your head. There is no perception, there is only, you know, monologues going in your new head there is no perception. There is no perception. If there is perception, all noise in your head will just stop. If you're looking at something absolutely beautiful and engaging, everything stops.  It is the attention which is making the difference. It is not what's playing on the screen. It is instrumental in grabbing the attention. But it is the attention, continuous attention which is making the experience of being there. So this is a rudimentary form of meditation. It's called dharana. So how does one in today's time retain that attention? One simple thing is everybody must do something about themselves. Every child, every school should bring this dimension that a child is required to pay attention to something continuously. It could be music, it could be dance. See you cannot do music or dance unless you pay attention to it, you know.  But you can pass an examination without attention. That's right. Above all, if you just, I've seen this simple thing. Children came to us, we have a Isha homeschool which is a very, run in a very different way. I one day went to the assembly of your old kids. They're all like this, like this, like this. I said, why are the kids like broken tops? Why are they shaking around like this? Then I just brought this thing. Simply every day in the morning, sarigama padanisa, fifteen minutes, everybody must do. You go there after two months, they're all sitting like this. That's all it takes. If you just make them walk in the forest in the night one night, in the darkness, you just make them walk, you will see they will become like this. Their ability to pay attention will become like that. Their sense of wonder will explode. You just take them into the jungle, make them walk for a night without torches, without cell phones, without anything. In a protected atmosphere, you will see within one night there will be tremendous transformation in the sense of wonder in the child's life. But we are making them physically incapable of these things. Sitting just in front of the computer, they will be incapable. When physically it hurts, they will protest. They will not do anything. So it's something that parents must take care of.  Your child, in the body and mind should grow up to full capabilities. That is when he will manifest in his life as success. A hopeless cultural and economic situation. But no systematic way of taking the rural masses to education has not been done. As part of Satguru's vision to improve the situation in rural Tamil Nadu, Isha Vidya offers affordable quality education for children to create joyful, fit and capable youth. Eight Isha Vidya schools are creating a bright future for 4,050 rural children, many of whom are first generation schoolgoers. Around 40% of the students pay a nominal fee and 60% are supported through scholarships or educational support. Midday meals with 11 essential nutrients and protein help to address malnutrition. Isha Vidya schools strive to make children understand their system computer skills while preserving their tradition and culture. In 2012, based on the success of this schooling system, the Government School adoption program was launched. The Isha Vidya team are training teachers from 31 Government schools around the state to improve children's English, provide special attention and hygiene into school life. The Government School adoption program has reached over 26,800 students around Tamil Nadu. If you have 1 billion people illiterate, uneducated, this is a huge liability for any country. If you have 1 billion educated, focused, disciplined, committed and inspired population, it could be a miracle. For the first time, we have this opportunity, this generation of people. We can take this whole mass of below poverty line 700 million people from one level of living to another in just a matter of 10 to 15 years.


Because if you cut even one to two ounces of something or you're lowering my carb or raising my carb, you're throwing my numbers off by 200 calories, potentially 150, 100, it doesn't matter. If I eat 21 meals of yours a week and my meals are off 100 calories, that's 2,100 calories that you have changed my meal plan for that week of total calories I need to take in, whether it's a surplus or a negative. So if it's a negative, then I am now suffering a lot more than I should be during that deficit that I plan to be in, which then can lead to the plateau of me now cheating. I got a binge, I'm going crazy, I'm yelling, I'm frustrated, the psycho comes out if you're too hungry. And that's something I teach my clientele when I start helping them diet down is I will do two week check-ins with them until I have them where we're not at that borderline crazy. So tampering with someone's numbers is a huge deal, especially if they're trying to lose weight.


DigiKey and Adafruit present. Duh-duh. I am an MPI. Texas Instruments is our featured company on INMPI This Week by DigiKey and Adafruit. Lady Aida, what is this week's INMPI? OK. So this week's INMPI, as always, I go to digikey.com slash new. And I'm like, what is the new? Well, I used to do this all the time anyways. But now I'm sharing with you the thing that I found on that page that was the most interesting part of the week. And this week, it's this new Buckboost converter from TI. I love TI power regulators and Buckboost converters. They like, there's so many different ones. They cover like every range. They're super powerful. They're very integrated. And they always have these like touches that make you think like, wow, this person who designed this chip really thought about some cool and useful new functionality. I mean, power supplies are supposed to be like boring. But actually, they're kind of not. They're the most important part of your design, like the base of the design. The good power supply makes everything work out. And a bad power supply is going to cause you all sorts of headaches. So this week's MPI is the TPS, which I think is like Texas Instruments Power Systems. I don't know exactly what the TPS stands for. It's the TPS 63900. And this is a very tiny little chip that is a Buckboost converter that takes about 1.8 to 5 volts in and gives you a selectable 1.8 to 5 volts out. Here's a simplified schematic. So one thing you'll notice is, of course, it's a synchronous. It's the transistors are all internal. So you don't need an external transistor. You don't need an external diode, a shocky diode. It's really easy to use. You've got an input capacitor, output capacitor, and then the inductor. One thing that's neat is that this is a Buckboost converter, only one inductor needed. And it's about the same price as a Buckboost converter, but to get both peanut butter and jelly together in one. When you have a voltage, let's say you want to have a voltage of about 3.3 volts. That's a pretty common voltage for most electronics. But you're using something like a couple alkaline batteries or using a lithium polymer or lithium ion cell. Well, a lithium ion cell or lipoly is going to be 4.2 volts when fully charged. It's higher than your output desire of 3.3. But then as the battery gets run down, it drops down to as low as 2.7 or even 2.5 volts. And that's below 3.3 volts. You want to boost that voltage up. So what's nice here is no matter what the V in is, between 1.8 or 5.5 volts, the output is going to be a steady voltage. And it will automatically switch between the two modes of operation in order to maintain that clean 3.3 volt output, which is wonderful. This means you're getting the most power out of the battery, really just draining it, but also getting the exact voltage you need. And something that's interesting that you can see here is there's those three configuration resistors. We'll chat about those in a moment, because this Buckleys converter has an interesting dual output selection mode. OK, so one thing that I thought was neat is if you go to TI's YouTube page, they have a whole webinar that is 45 minutes long, and it talks about all of your different buck boosts. They talk about this one, but it also has this nice diagram that shows you their family of boost and buck boost converters. And there's a lot of chips that TI makes for this power regulation and boosting. So I thought this was handy to kind of bookmark this. I want to go watch this in more detail after the show, because depending on your current outputs and your quiescent current, you might want to have a different selection. So this chip, you see, it's right there in the middle. It's that sweet spot. It's got an internal switch of about 1.5 amps. Note that doesn't mean that the output is 1.5 amps. It means the switch that is inside that does the boosting or bucking or multiple switches is about 1.5. The actual current you're going to get is, I think, for boosting, it's about half an amp at 400 milliamps. And then in buck mode, I think it's about 600 milliamps. So it's over 300 milliamps or so, depending, of course, on the voltage input output. But what's really nice is the ultra-low quiescent current under a microamp. That's not on a typo. It's not under a milliamp. It's under a microamp for the quiescent current, which means that this is an excellent chip for use with wireless devices that you only need to send data once in a while. So this is what they're kind of picking. They're sort of saying, this is really good for your Lora WAN. This is really good for your BLE. This is even good for maybe something that is Wi-Fi. Something that only wakes up once in a while. But you do need to have a really good solid power supply at that time, and that spends most of its time asleep. So they're like, why ultra-low IQ DC DC needed? And usually DC DC are not low quiescent. Usually that's one of the things that you give up when you move from an LDO to a DC DC. But especially when you have these devices that, again, they wake up once a day, once an hour, they take a measurement, they transmit it, and they go back to sleep, the quiescent current becomes the dominant power usage. Even though it's extremely low, the amount of time that you're spending in that low power mode is so long that it actually starts becoming, that the quiescent current starts to really matter, even though it's so low compared to the running current. Maybe it's like three orders of magnitude less, but it's three orders of magnitude as long. So that's why for wireless, they call this pulse-load applications, the quiescent is important. So I thought that this was a really nice little chip that can handle, kind of does a little bit of everything. It's like a bento box of converters. It's got some nice specifications. You can see there, it can give you up to over 600 milliamp output if you need. So you can use it for some low power, not multi-amp, maybe not like cellular wireless transmissions, but definitely will do your Bluetooth, your BLE, your Lora, your ZigBee, your Z-Wave, all those things, which, again, low quiescent, long time asleep, wake up once in a while, do something. This is the other thing that they had, which I thought was, at first I was like, why is this at all interesting? Then I thought about how you would implement it if it wasn't built into the converter.  So it's really nice it's built in. So when you're doing your measurement, let's say you have a little Bluetooth wireless temperature humidity sensor. And you want to take a measurement every five minutes and transmit it to HomeKit, your hub that is measuring data from around your house. This is a home automation project. So for that, you're going to be asleep for five minutes. So that's where the low quiescent current is so important. And then you're going to wake up. And before you turn your radio on, before you turn on the Bluetooth or Wi-Fi or whatever, you're going to want to get some things going. You might want to configure your memory. You might want to read some EEPOM. You might want to take some sensor readings. And all that can, maybe it's not going to take that long, but it does matter. And for those sensors and those devices, you might be able to run at 1.8 volts. And if you're in an LDO mode, only it won't be that important. Maybe it doesn't matter.  By starting up and running your MCU at 1.8 volts to take advantage of that lower voltage and not turn on your radio, which is going to be that high current, higher voltage, that's going to need 3.3 volts or 4 volts or whatever. And then right when you're about ready to transmit, boom, you tell the DC-DC converter, hey, instead of giving me 2 volts, give me 3.3 volts, everything powers up much higher all at once.  So to do that, if you go back to the first image, sorry, the second image, the first if you count by 0, on the right you see the config resistors. So those resistors, normally, if you've made a couple buck boost converters, you're like, hey, where's my resistor divider? Usually you have a resistor divider on the output that sets the output voltage. That's how it's going on here. Instead, it uses these single resistors to set the voltage, and you're probably like, well, how do you tune the voltage? Well, there's a table, and the resistor value correlates with an output that goes up by 100 millivolts at a time. But check out the datasheet. There's a whole table there. So you have three resistors. The first two, I think, are the two voltage output options. And the third one is the input current limit, which I won't cover here. Again, the datasheet in the webinar does. And then if you see on the left, there's the cell select line. Well, when that pit is high or low, it determines which output voltage you're selecting. And if you think about, well, how would you do this normally? It's like, well, you could do it by messing with the voltage divider on your DC-DC converter. But some of you have all these transistors on their low side, and you have to switch them. And you have to switch them instantly so you don't get both off at the same time. So you actually understand why they're like, have this all integrated and have a little selector, and it does the logic for you. So I think this is kind of neat. It's an interesting thing of, OK, you really need to, you know, you have a small battery. Maybe it's a coin cell, or maybe it's like a 50 milliamp hour battery. How do you run your hardware as long as possible? And I think this is a, it's a not expensive chip. It's like $1 or so, and it does the job quite well. So this is on DigiKey, and you can find it by using the short URL, digikey.com, or you can look at this part number that's on the screen, or you can follow the links that we have in the blog post, or in the channel, or more. It's easy to find. Lydia just shows you how, and that is this week's. OK, I will show you really quickly. If we go to the overhead, I'll show the valve board, which I picked up. TI makes a nice, simple valve boards. So you're like, what's going on here? So this is actually all of the converter, right? This little section here, you've got this inductor. It's actually like a chip style inductor. Input output capacitor, a lovely little layout. They have some options for bigger capacitors if you want. And then these are all of those resistors. Remember I said the resistor sets the output voltage in the current limit? Well, you would use these to set this value here. You can see the switch here for the different values you can set, and that correlates with an output voltage and a current limit. So I think it's actually one of the few times where I'm like, if you really have to mess with all the resistors, it's kind of nice that these all come with dip switches ready to go. But the full solution is so small. And then, of course, these can be a 402 resistors. So really, it's only a few millimeters square. Just about everyone in the chat was saying, I was looking for a boost converter. Love DC boost converters. This is awesome. Thank you for the ideas. This is one of, I think, the best MPIs that you've done this year. It's useful. OK, I'm going to use it. This week's RMPI. Hi, I'm MPI.


Hey, this is Brett, and this 2021 Ford F350 Crew Cab Long Box Dual Rear Wheel Platinum Edition is stock number 14440Z. I am here at Summit Automotive in Fondlack, Wisconsin, your new and used heavy-duty truck headquarters. This 2021 Ford F350 has the 6.7-liter Power Stroke diesel engine. It puts out 475 horsepower, 1,050 foot-pounds of torque, and it's paired up with the 10-speed automatic transmission. This truck has been fully-safetyed and inspected by our service shop per the state of Wisconsin inspection process. It has a fresh oil and filter change, all the fluids have been checked and topped off. This truck is 100% ready to go. It's got a lot of really cool accessories that I'm going to get to, as well as extremely clean. That's exactly what I'm going to do in this video is go all the way around this vehicle, inside, underneath, start it up, take a look under the hood, show you all the options, and give you the most accurate representation I can of the truck so that you can see just how clean it is. Star White Tri-Coat Metallic is the color. I shoot all my videos in 4K. If you like the video, subscribe to the YouTube channel and get updates on all the vehicles I do each and every day by hitting the bell notifications. By doing that, you'll stay current on our ever-changing and vast inventory here at Summit Auto so you do not miss out on gems like this one. This one comes with Michelin LTX 80 tires. These are LT24575R17s. I would say they have probably about 50% to 60% of the tread left on them. Frame and underbody is exceptionally clean on this truck. This is a one-owner clean title history, clean car fax out of Ohio. Front fenders absolutely perfect. This one comes with my favorite heavy duty headlight group, the LED headlamps running lights and fog lights. We're going to turn all those on at the end of the video so you can see just how bright they are. Front bumper and lower valance are in very nice condition. I didn't see any major dents or dings on the front bumper. You also get the chrome trimmed grille. The 360 camera, the hood is absolutely perfect. No dents or dings on there. Also comes with cab lights up top, passenger side front fender, absolutely perfect. The passenger side front wheel is in very nice condition. Star white tricote metallic, it's got a lot of sparkle to it. Definitely a lot more than the old white pearl that Ford had, which was white platinum, but really a cool color, a lot of metal flake in there. As you go down this side of this 2021, take note of how clean the body is, how reflective and mirror-like that paint is. I take these HD videos so if you're far away or even if you're close by and you just cannot make the trip down, but you're still interested in purchasing the vehicle, you can see the truck here, the truck, and have confidence in the vehicle that you're looking at before you even get here. So when you do get here, there's absolutely no surprises. You can make a smart and informed buying decision from wherever you're at. If this video helps you make that buying decision, let your salesmen know that you saw the videos helpful and that Brett sent you. Very clean on that side, the dually tub, no rock chips or anything on there, looks really good and these back wheels are in fantastic condition as well. Tires have just as much tried as the front. Back tires has the camper package with the anti-sway bar there, frame and underbody is in really nice shape. Just like that all the way underneath has all the remaining factory exhaust. Very little to no corrosion and lower rockers, cab corners all look great as well. This one does have the power running boards, which work nicely. Dually tub, no dents, dings, scratches. It also comes with the chrome tipped exhaust coming around to the back. You get the LED tail lamps, the rear bumper parking sensors that rear bumpers in great shape as well. Full towing package, which includes a receiver hitch, 4 pin and 7 pin wiring. You get the platinum and fascia on the tailgate there that looks really good and the tailgates in excellent condition as well. This one is going to have a power drop down tailgate. It also has a Truxedo Low Pro rolling tonneau cover. I got a roll up tonneau cover, I got one of those on my truck, I love it. Like I said this one comes with some really cool accessories. It has the Ford factory 5th wheel hitch in it. It's a 32,000 and a half pound hitch. Also 5th wheel and goose neck prep package. You also have the LED bed lighting back here and then 7 pin wiring and then this is a hookup for your trailer backup assist system.  Imagine this person had like a motorcycle or a 4 wheeler that they locked up because it has the ramps that go with this tailgate piece. They slide onto this lip here and then they stay on the lip. You can see they're all set up for that. So that's really cool as well. Comes with those ramps so they will be in the truck when you come to pick it up. That spray and bed liner goes onto the tailgate. That is a Ford factory spray and bed liner, a tough bed if you will. And then you get the tailgate step assist. Tailgate shuts nice and solidly and I'm coming down the driver's side just as clean as that passenger's side. No major dents, stings, scuffs or scrapes on the box. And for full disclosure, this back wheel just as nice as the rest. Really a clean truck. Would not mind having this one pulling my camper. Going down the rest here. Doors look great. You get the power scope mirrors. They power fold in, power telescope out. They got blind spot monitoring, LED lights on the mirrors, directional signals, the 360 camera has the intelligent access on here, the driver's side door code entry. We do have the code for this truck. If you ever wanted to figure out what your code is for your 17 to 22 Super Duty in the upper right hand part screen, I've got a video showing you how to do that. These back seats are heated on the outboard side. You get the black leather with the gray kind of metal looking insert, but that's a different type of fabric. You get the platinum badges on the backrest, power sliding rear window with the built-in rear defrost. Seats are absolutely perfect. You get the wiring for that trailer back up assist system. You also have the side box tie downs, collapsible floor. You have the kit for the gooseneck and tie downs there, weather tech floor mats throughout on this truck. You also have heated seat buttons, USB, USB-C and 110 volt 400 watt plug-in. You also have a 12 volt power point right there and like I said, very, very clean back here.  So the doors all look fantastic. Show you the VIN sticker, no previously owned in Canada trucks here. Tire and loading information sticker as well.  Both these front seats are heated, both these front seats are cooled. No rips, no tears, you get the platinum badge on the backrest. Both these seats are power driver side lumbar. These have the massaging seats in them. My favorite option on these trucks, platinum and king ranches, weather tech floor mats up here. Power drop down tailgate, power pedals, auto headlamps, power tilt and telescopic steering wheel. See that's working nicely. Power windows, locks, mirrors and memory driver seat get this really cool kind of wood grain, almost carbon fiber looking trim there. These mirrors do power fold in. I always like showing both sides so that you know that both sides are working properly. You also get the power telescope and telescope in there. So hop inside, check out the miles, the radio and everything that this one has to offer on the interior. And yes, we will be putting some fuel in this truck right after this video. Digital speedometer, 4,924 miles on this truck compass display, instrument cluster is very nice and clean. Comes with the leather wrapped steering wheel. This is a heated steering wheel, Bluetooth and audio controls on the right. Cruise controls, adaptive cruise controls on the left and information center controls on the left as well. There's your shifter for that 10 speed automatic transmission with the optional tap shift. And this one does have the B&L premium sound system. You get the sync eight inch radio does have the factory navigation system. There's highway 41. So that is working nicely.  And then you get all your different apps as well as FordPass Connect, Android Auto, Apple CarPlay. Then here are your seat massaging seat controls. So it'll massage the back and lower part of the seat and just the best thing ever. Here are your cameras, your 360 cam, your front view cam. You also get a wide view of the front. You also get a cargo cam. So when that tonneau cover is rolled up, you can see what's going on in the bed of the truck. And then if you wanted to add a camera, like say to a trailer or something, you could do that as well. And then of course, your normal 360 cam right there. So a lot of great stuff you can do with this radio and everything is working very nicely. Side lane departure warning, hazard lights, stability control, factory exhaust break. Down here is your turn dial, four wheel drive, your factory brake controller. Your trailer backup assist system. Down here your more tactile, volume tune and climate controls, including your dual climate controls, heated and cooled seat buttons, and your wireless cell phone charge pad. You also get a USB-C and USB in there as well. Down here are your cup holders. So this is my magic trick. You get two cup holders, Abra Cadabra, four cup holders. And then it has ambient lighting in there as well, keyless entry, remote start, and power drive plug-in. Here's your 12 volt power point, 110 volt, 400 watt max plug-in, dual glove boxes, and the passenger side format and seat are in fantastic condition. Headliner is very clean on this truck. Looks really good. You get your power side and rear window button, map lights, and your home link buttons for your garage door security systems and lighting systems. All right. Let's start it up and take a look under the hood. No check engine lights or anything like that, and I did want to show you that the backup camera is working. This one does have a backup beeper on it, so that is installed. Let's turn on those lights, take a look under the hood, and check out under there. So here are the LED side lights, nice and bright. I would personally like to thank you for checking out the video today, and hopefully from this HD video, you've been able to verify the quality condition options, and of course cleanliness of this truck all the way around inside out. I just really like the look of those lights, and they're very bright as well. Cab lights working well too. Under the hood, we have the 6.7 liter power stroke diesel engine and engine base. Very clean. Runs very smooth. Once again, this truck has been fully safe and inspected by our service shop as a fresh oil and filter change, all the fluids have been checked and topped off. Shocks are doing a great job holding that hood up. The light is working. There is the emission sticker. And this truck is 100%. Ready to go. I would highly recommend it from a quality and condition standpoint. Like I said, I wouldn't mind having this one in my driveway pulling my camper, and I think whoever is going to get it is going to be a very lucky person.

Okay, in this video we are going to talk about setting a readiness probe. So readiness probe basically tells Kubernetes that the container is ready to start accepting traffic. And if you're running Spring Boot 2.3 or higher, this will be available in the Spring Boot actuator. So very important that you're on a more modern version of Spring Boot to have this functionality. Otherwise, what I'm showing you in this video will not work. So again, it's Spring Boot 2.3 or higher. And we need to do two things here to enable the readiness probe. One is to set the environment properties for Spring Boot actuator to enable this. And then the second is to tell Kubernetes to utilize it. And we'll do both of those in the deployment YAML, the descriptor for our Spring Boot application. So here you can see for the environment property, we'll go ahead and work on this. So again, this is going to be a name value pair and YAML, this is going to be a list. So we'll do name. And in this case, it is management underscore endpoint underscore health. Again, this is for the Spring Boot actuator. So management endpoint health probes enabled. Just double checking to make sure I don't have a typo there. And in this case, we want to give it a value of true. And we also need to go ahead and add in a second property, and this is going to be management. And we'll do readiness, and again, the value would be true. And then also we need to set up a new property for this. And this is for the Kubernetes configure. So these two environment properties that we set are going to basically tell Spring Boot to expose the probe. And now we need to configure the probe for Kubernetes to use it. So the way we do this is set up readiness probe. So that's going to be an HTTP Git, port 8080. That's the port that Tomcat's coming up on, the default port. And then path health readiness. So that configures Kubernetes, telling Kubernetes to go do an HTTP Git against port 8080 at that path of actuator health readiness. So let's go ahead and write this file. And then kubectl, ply minus f, deployment, and made a mistake there. Let me pause this and resolve this. So I took a closer look at the problem there, and Kubernetes is expecting these values to be explicitly strings. And it did not like the unexcaped boolean values, but going ahead, setting those values to strings using the quotes. I think with YAML, you can also use single quotes that did clear up the problem. So I reloaded it, it did load up properly. And let's go ahead and quit out of the YAML. And you can see the kubectl Git all, and let me clear this and get a better view for you. You can see that we are up and running properly. So the readiness probe is working. And let me toggle over to Postman. You can see here I'm going to actuator health readiness. I can go ahead and send that. And we can see that endpoint is being exposed, and we are getting a status back of up. So that is the desired response for Spring Boot actuator. So I'll go back over to the terminal. And just to recap what we changed here, we added in the environment properties for management and endpoint health probes enabled, and then specifically management health readiness state enabled. And then we do have for the boolean properties, we do have to escape those as proper strings. And then to tell Kubernetes to use the readiness probe, we are doing readiness probe, specifying an HTTP Git on port 8080, and that goes to the Spring Boot actuator health readiness URL. And you can see from the Postman example that path is exposed and returning back an up status for us.

Today on CNN, openly socialist hack Alison Camarada interviewed the disgraced former lawyer of Donald Trump, Michael Cohen. Fresh off house arrest, he threw himself on the Democrat State altar for forgiveness, prashing Trump as a cult leader and even suggesting the mass imprisonment of 70 million Trump supporters. His goal is to convince you that he won the election and he has done that with this percentage of Americans that are so deep into the cult of Trump and trust me, I know about the cult of Trump, I was one of its leaders, maybe one of its founders and I see exactly the stupidity of people as I walk in the city or I get certain text messages on occasion from individuals who are so entrenched into this cult that they can't see straight. What's the answer to getting out of it? Maybe incarceration? I'm not sure the prisons are big enough for all of that. This CNN segment was sponsored by Carvana, Coventry Direct, Dell, Sandals and Walmart.

So when I landed in the writing classroom, I would say things like writing is a social activity and it's a myth that the writer just operates in isolation. But there's a there's a difference between being able to say that and being able to show it. And even though I would do group work in the writing classroom. I felt that social annotation was a tool to take it take it back several steps and allow students to realize that that reading was key but but thinking and having conversations about what one is reading is I think really what pushes one forward in the process. And specifically for my campus we have a largely commuter campus. I would say probably 90% of our student body commutes to campus and most of our students have jobs and lots of responsibilities outside of campus and it's very very difficult for them to make connections in often right when they're right there specifically on campus so annotation gives them another opportunity to engage and to see what their classmates are thinking and to to to see asynchronously what's going on. And then I found that it really fueled our conversations in the classroom when when they could look and see oh yes, I had the I had that same thought or I had some of those similar questions as I was reading.


Hello, everybody! This video will show you how to create a USB reanimator with Windows PE to help you boot your computer without an operating system. Such USB drive will not only allow you to boot your full-fledged Windows without installing it, but also use various software to check your hard disk, search and remove viruses, create new partitions, and so on. You may need such plus drive if your computer's operating system fails to boot, if it needs to be cleaned from viruses if you want to restore its normal work or recover important data. There are several ways how to create a reanimator USB drive or live CD on your own, but it takes certain skills and experience. To my mind, it is easier and more convenient to use a reanimator-reanimator build based on a boot disk, for example, well-known builds by Sargey Strelets. In order to use a reanimator boot disk, download it from the link in the description. As a result, you will get an archive. It contains several files and folders. In our case, the main file is WinPE10, the image of the boot disk. In order to use it, you should save it to a flash drive. That is why I expect it first. The password to the archive is shown in the web page where it was downloaded from, and I will give it in the description of this video. In the archive, in the folder named Rec and to Flash Drive, the author has also put several programs for writing the reanimator image to a flash drive. As I already know, such program as Altra ISO, I will use it. I start it, now select File, Open, and specify the ISO file of the boot disk. After that, insert the flash drive into a USB port and select Bootable, write disk image. Specify the flash drive and click write. That's all. The bootable USB drive is ready. Now, if you need to boot your computer with a flash drive you have just created, insert it into a USB port of the computer and set it to boot from the USB drive. You can watch a detailed guide on how to do it in another video on our channel, how to antibuy so you can apply and boot your PC from a USB drive. You can find the link in the description. After that, the computer will boot showing you this kind of window. This is where you can choose to boot from the USB drive, find and boot a selected operating system or test your system memory. Select booting from the USB drive, boot USB. When files are loaded, the operating system starts to boot from the flash drive. When this process is over, you will see that the operating system of the reanimator USB drive has an interface similar to Windows 7. I'd like to point out that in the folder diskPC you will find all disks of your computer. In my case, there is diskC. It means that with little effort, you can copy all necessary files from diskC to any other disk connected to your computer or to a removable disk, and then feel safe to reinstall your operating system with disk formatting. Depending on what you want to do, you can start and use one of the many pre-installed programs. All of them are available in the menu, start, programs. They include antivirus software, system backup and restore utilities, as well as data recovery programs including Hetman Partition Recovery. In addition, at this stage you can defragment or format your disks and so on. Please note the shortcuts on the desktop. The author of this build has also taken care to let users have access to disk management menu which you can use to delete, create or format a partition and so on. Connect network drives, for example, to copy data to such drives. Access Device Manager if you need to fix problems with one of your devices, for example, reinstall drivers. You can unlock a disk encrypted with BitLocker, and you can start a disk port command in the command prompt and do many other things. Now you can see that a reanimator disk or reanimator USB drive will come in handy in a situation when the operating system fails in a computer with important data and reinstallation can result in a loss of data. To finish with, I'd like to remind you that you can also create a reanimator USB drive or live CD on your own. It is possible if you use special software for boot disks such as the free program, AOMEI, PE Builder and the like. When you work with such software, you can even improve your reanimator drive by adding the programs which you want to have for your special needs. You can find the link to AOMEI PE Builder in the description. That is all for now. If you found this video useful, click the like button below and subscribe to our channel to see more.

I'm Zor. Welcome to Unizor Education. I will present problem number three for mathematical induction. Here's the problem. Let's assume you have a certain number of lines on the plane and we will assume that there are no parallel lines and there are no lines which cross no more than two lines are crossing in any particular point. So I am excluding this case when there are parallel lines and I'm excluding case when three lines are crossing in exactly the same point. So this is not happening. We have only non-parallel lines which are with crossings of no more than two lines in any point. The question is how many cross points we have in case of n lines? Well in case of one line obviously we have no crossing. In case of two lines obviously we have only one crossing right? Two lines are crossing in only one point. No parallels. In case of three lines so this is n and this is cross. In case of three lines as you see here we have three crossings. Well let's just go on in case of four. Well four actually does something like this right? It's not parallel to anything which means it's crossing anything. I added one to three points so I have six. So these are my sequences. It looks like the formula should be very easy and I'll just give it to you and you will try to prove it. The formula is n times n minus one divided by two. Let's check it. For one it's zero because this is zero. For two this is two this is one divided by two it's one. For three three times two divided by two it's three and for four four times three twelve divided by two six. All right so that seems to be like with right formula. Okay try to prove it using the method of mathematical induction. Press the pause button and do it yourself and I will try to prove it here. So the formula is n lines no parallels and cross two lines only. No three lines are crossing in the same point. And the formula which I would like to prove is that the number of crossing points is this. All right let's go through the steps. Step number one check. Well we have already checked for one two and three formula actually holds so the check is fine. Let's say for n is equal to one for one line. The formula is zero no crossings because there's only one line within that. Okay assume what do we assume that n lines of that type cross in let's look this way k lines I don't want to use n anymore. Let's assume that n is equal to k. So we have k lines are crossing in k times k minus one divided by two points. And three we have to check that the formula is correct for n is equal to k plus one. So let's just draw another line. We have k lines. We draw another line. As I said no parallel lines which means this new line will cross each and every one of those old lines. Now all these crossings will be new because no old cross points should be crossed again because I said no more than two lines are crossing to the same point. So whenever we draw the next line the k plus first line it crosses all the old lines which means it introduces new k points of crossing. So when I have n equals to k plus one I actually add k points crossing points. Well let's see if our formula will will be held in this particular case. So we used to have we assume that k lines by themselves are crossing in k times k plus minus one divided by two lines. I introduced k new points. And how the formula will look? Well that's easy. It's k times k minus one plus two k divided by two equals k. Let's factor out k and what will be? Will be k minus one plus two which is k plus one divided by two. Now let me just rewrite this formula slightly differently. Since I need space I will wipe out this. Instead of k I will use k plus one minus one. That's the same thing, right? So I assume that my formula for n equals to k looks like this and for n equals to k plus one we derive that the formula looks like this. But as you see this is exactly the same formula, right? k plus one this is instead of n we put k plus one. So the formula looks exactly the same way. It's number n whatever the n is in this case in this case is k plus one in this case is k. Same number n minus one. So the formula is exactly the same. So for n is equal to k it's this one and for n is equal to k plus one formula has exactly the same form and shape. So the formula holds and that actually proves the whole point. So if you have n lines on the plane they cross under these conditions obviously no parallels and no more than two lines are crossing at the same point. So they cross each other in n times n minus one divided by two points. And now here is an interesting thing. If you remember looked at the lecture which we started mathematical induction with we started with a summation example which young Carl Gauss when he was seven years old he added up numbers from one to one hundred. And obviously what happens with lines on the plane is exactly the same as what happens with numbers if you are adding numbers from one to n. Why? Because each new crossing is introducing the next number in this summation. So if you have one line you have zero crossing. If you have two lines it introduces crossing with old lines. If you have three lines it introduces new two crossings with old two lines. If you have four lines it introduces three new crossings with three new lines. So as you see this is exactly the same thing. So if you have n that's n minus one actually. So the number of crossings if you have n lines is a sum from this to this. And that will be exactly the same formula. Okay that basically concludes this problem number three. Thank you very much.


All right Adam you want to take us to a surf daddy? Yeah surf daddy has a question that I think a lot of people often have I get this one a lot. So I'm looking for a way to automate arrange windows based on whether my m2 mech book 13 inch air is using the built-in display or in clamshell mode. I use a Samsung M80c 32 inch 4k monitor both displays are set to more space Yeah, there are there are lots of ways to do this I absolutely need this on especially on my podcasting rig, but really on on all of my computers Even if the displays don't change apps sometimes don't go where I Wanted them to be maybe I left them in the wrong spot or maybe I they just decided on their own so I use a piece of software called stay from cordless dog and And it you you get your windows where you want them you tell stay Stay and it remembers and what's cool is to your question Surf Daddy it will remember different configurations for different monitors So if if you're on your laptop with an external monitor You can have you can put things where you want and hit save and stay will remember that and then when you change You know Disconnect your external monitor move things around hit save and it will save it for that configuration And you can have it auto switch when you plug in your external monitor be like, ah, I know what to do And it'll go and like run things over to the side. So Yes, that's one in our discord where this question was asked Jeff answered and suggested the app called Moom MOM from many tricks and that does a very similar thing It has a slightly different user experience and you might like that better I I actually kind of like the way Moom does it but I started with a stay and you know momentum is what it is But you stayed I stayed. Yeah, I did what it said. Yeah


We're going to talk about our four different kinds of biomolecules and I'm going to see if this works out for me to have one page where we keep track of all the little bits and pieces of information about each one of them. I'd love to have one I Don't know one chart that includes all the information. We'll see if I can make it fit for categories of biomolecules, carbohydrates and I mean right there. I already am I don't know. I may have to do some adjustments to make sure I can fit everything on here Let's look at for all of them will do this, but I want to look at the subunit. All All biomolecules are made up of building blocks like they all have a thing that if you string a whole bunch of that thing together You get the biomolecule and you can get great complexity because you can mix and match how you put those things together Okay, I don't know if that makes any sense at all, but carbohydrates all of them This is wild. All carbohydrates have a C H wait a C H oh H 2 oh a C H 2 oh, I knew I could get there Subunit Which means they all have the same They they're gonna have different numbers of carbons But you can add you can have 20 carbons and you'll have 40 Hydrogens and 20 oxygens, so they all have that same pattern They also can be found in You can have monosaccharides. Oh, I can never remember how to spell saccharides monosaccharides Which are single? Um Single subunit Single unit Carbohydrates, I'm just gonna give you an example glucose is a monosaccharide You can put them together to make other stuff like disaccharides We're just gonna make it.   This is gonna take me one second There we go. Yes, that's what I would like you to see. Oh goody. That wasn't that bad These complex carbohydrates are polysaccharides and each one I don't know if you can see my mouse each one of these little circles on all of these is a Monosaccharide so you can see how we've put together all these monosaccharides in these strings to make different Complex carbohydrates. We have starch starch is a complex carbohydrate that you find in potatoes other delicious items Glycogen is a complex carbohydrate that you find in your liver. It's the way that your body Stores glucose for energy Cellulose is a complex carbohydrate. It's we can't digest cellulose. So it makes up dietary fiber for us But it is made of all these monosaccharides and then there's this one called chitin chitin has just Nitrogen atoms added and it's found in the exoskeletons of like crabs then Saubugs and other crustacean type critters with shells. They have chitins Oh and some fungi have chitin in their giddy ups. They use chitin Which is a string of monosaccharides and guess what? This is the crazy part about to blow your mind starch glycogen cellulose and chitin are all made from strings of glucose Nothing more You string together glucose in one way and you get starch you string together glucose in another way and you get glycogen String it together in another way and you get cellulose and string it together in another way and you get chitin Chitin is the only one that has a little bit of chemical Uniqueness with the glucose molecule because it has an extra nitrogen that replaces some other molecule I don't know if it replaces a carbon or what it replaces in there But they still consider it's basically glucose with this weird nitrogen Modification and it and it's a complex carbohydrate that has a totally different function Carbohydrates are usually energy providers and Or structural protection Lots of critters can eat cellulose cellulose is like the most common Complex carbohydrate on the planet I think and just because we can't eat it doesn't mean or digest We eat it and dietary fiber is super good for us, but our bodies can't digest it on Their own lots of things can't digest the cellulose on their own. They actually end up Recruiting bacteria to help with that task. Okay Carbohydrates we will see them we will build things with them We use them in all of our cells as signaling molecules and Fuel and we will see them over and over and over again, but now you have the basics


Hey, I'm Kerpaloo from the Van Converge and God City Recording Studio. Which black star amp do I use? Well, I have an Artisan 30. I have one in Europe and one at home in the States. And I really enjoy it. I've always really loved sort of Vox AC30 derived and sort of, you know, the classic British E-L84 Open Back 212 style amps. There's like, something about the Open Back 212 cabinet has the right balance of focus and openness. And there's like a chiminess to it, but there's also a throatiness. It just seems to be like a really well-balanced, basic kind of rock guitar amp. And I think black stars really kind of dialed in that design and further and given it like the sort of depth that it needed in order to be right for the kind of playing that I do. Something about that cabinet is just like the perfect size and shape and it just always records great. I think the black star amps work really great in a live scenario, especially the models that have some power scaling or some sort of wattage adjustment built into it. I find that a lot of places, particularly when we're touring in Europe the PA systems are not loud enough to handle really cramped up guitars through them. And I want the audience to be able to hear the drummer and hear the singer. And when I'm on stage, I want to be able to hear the drummer as well. And I'm sure you can all hear the drummer right now. So an amp that has the tone of loud while still being able to be played in a manageable volume is something that I'm always on request for. I think particularly with the Artisan 30 and the Series 1 amps, they're really nailed back. My relationship with black stars has been great. They've been very accommodating. Whenever I've needed something and I've gotten in touch, they've been quick to respond to me and help me try out and find the right amps that will work for me. And I've really enjoyed working with them so far. Well, currently Converge is on a two-week European tour where we're playing a mix of club dates and festivals. And when we're finished with this, we've all got some personal life stuff to do when we get home. I'll be back working in my studio. I have a lot of upcoming great recording projects. High on Fire, for example, is one of my next big ones. And then after that, we're going to get back together and start writing some new songs. And hopefully, I'd like to say we'll record a record in 2015. I can't guarantee that. But hopefully, there will be new Converge material on the horizon. Hey, I'm Kirk Lew from Converge. Please check out ConvergeCult.com or GodSeedingStudio.com and definitely check out Black Star amps.


Hi, I'm Zor. Welcome to Unisor Education. I would like to start a new topic in algebra called systems of equations. System of equations. This is just an introductory lecture. There will be others related more to how to solve the system of equations. So this is just general talk about what are the systems of equations. I do recommend you immediately after you listen to this lecture to go back to Unisor.com and read again the notes for the lecture. I think it will be very helpful. Alright, let me first remind about what actual equations are for. Equations are certain numerical or algebraic rather conditions which we established about certain unknown variables. So if you have some condition about unknown variable which we call x, let's say 1.5 times x equals to 6. Now what does it mean? It means basically that there is some unknown variable which if multiplied by 1.5 gives 6. Now the next question is what is this unknown variable? Well, we have already learned that using certain transformations with the equation we can come to a conclusion x is equal to 4. This is also kind of equation but it's an explicit equation which actually shows the value of the x. So equation is a condition which we impose on certain unknown and which allow us to find the value of this unknown variable. Okay, that's clear. Now let's just do it in a little bit more formal representation. This condition which we impose on our equation can be expressed as an algebraic function f of x. And I will put it equal to 0 because I have to put some equation. Whatever the algebraic expression which contains x is, I can always reduce it to this particular form. Something like if 2x plus 6 is equal to 57, I can always say 2x minus 51 equals to 0. So it's easy to put it equal to 0 to give certain standard notation. So we are considering equations of this particular format that some function being applied against the variable will give the variable of 0. Now it's a condition and if we are able to convert this condition into something like this, that means that we have found a solution. So if we are saying that x is equal to a is a solution, it means that if a is substituted into this function, then I will have an identity, a numerical identity 0 on the left and 0 on the right. Alright, so now talking about systems of equation, the next step is, well, what if I have more than one variable? x is just one variable, what if I have two, three variables, n number of variables, whatever. That's actually how we are approaching the systems of equation. So what's important is that we have certain number, n whatever, of unknown variables and certain number of conditions these variables must satisfy. If we have these conditions satisfied with certain values of the variables, these values are called solutions. So let me just give you an example which is not necessarily like algebraic expression of our condition. Here is the one, for instance, x plus y is equal to 2 and another condition is x and y are integers greater than 0. This is also a condition. So I have one condition expressed as an algebraic expression and another condition is basically certain words which describe certain restrictions on our variables. Now, is it enough to solve the equation? Well, let's just think about it. If x and y are integer and positive, it means they are at least one or greater. So if both are equal to one, both are minimal, that actually satisfies the first algebraic equation. If any one of these is greater than one, then we will not have the first condition satisfied, which means this particular number of conditions, two conditions actually, also allow you to find the value of variables. Can I say that this is a systems of equation? No, because one is an equation and another is just some kind of words which specify the condition. So if all the conditions are specified in this algebraic form, then we can talk about systems of equation. So all conditions must be expressed as an equation. Now let's talk about certain examples first. Now, before I just gave you one simple example of two variables and two conditions which allow us to find the solutions. Now, these algebraic expressions, which we are talking about as participating in the systems of equation, can be absolutely different. Now, let me give you one particular example. x plus y is equal to 3, 2x plus y is equal to 4, and 3x plus 2y equals to 7. Now, is this a system of equations? Well, yes, it's a system of three equations with two unknowns. However, let's just take a look at one particular property. Oh, by the way, it doesn't look like something is equal to zero. It's easier for me to do it in this way, but obviously I can put it x plus y minus 3 is equal to zero plus 2x plus y minus 4 is equal to zero, and same thing. So it doesn't really matter whether I put constant on the right or on the left. Now, what's kind of peculiar about this particular system of equations? Well, look at the third equation. If you will add one and two conditions together, x plus 2x is 3x, y plus y is 2y, 3 plus 4 is 7. So what does it mean? If I found a solution to this system of equations, so if I found the value of x and the value of y, which satisfies these two, this will be automatically satisfied. So this condition is basically, it doesn't bring any new restriction onto our variable. It does not help us to find the unknowns. It does not bring any new information into whatever our knowledge about our unknown actually is. These two, they are independent, and we will talk about what is independent actually. But you feel that these two are completely unrelated to each other. And this one is dependent on the previous two, which means it's really extraneous. Usually, system of equations, whenever it's like presented to be solved, usually it does not contain anything like that. However, I mean, just as a trick, you might always expect something. But just, let's just be very, very clear. If you have one of the equations derived in some way from the others, then it doesn't really bring you any new information, and it can be completely discarded from the system without any laws of the villages to solve the system. Alright, this is just an example, for instance. So let's now talk about a general form of the system of equations. As I was saying, system of equations is a set of conditions expressed in an algebraic form. Now, what does it mean in an algebraic form? It means there is some kind of function, f, that's called function number one, which depends on a certain number of unknowns. And the condition is like this. Now, we have another function, which is also dependent on the same n unknowns, etc. And you have function by the number m of the same set of unknowns. And all together, we are saying that all these m functions represent a system of m equations with n unknowns. This is general definition of the system of equations. I'm not talking about linear equation, quadratic equation. This is all completely outside of the scope of this introductory lecture. We're talking about equations in general. There is an equal sign, and that's why it's equation. Now, I put zero on the right just for a definitiveness. And some function on the left, algebraic function. Well, which means we can basically know what kind of manipulations to do with x1, x2, etc. We can add, subtract, multiply, use exponential function, logarithmic function, whatever functions we use and their composition, that's what it means, algebraic function. So, all these functions used in this particular equation on the left. And all together, it gives you a system of n equations with n unknowns. Now, just to be on a semi-precise note, I would like to say that in general, if you would like to find out the values of n variables, most likely you will need n equations. So, the correspondence between the number of equations and the number of variables should actually exist. Why is a different question? I mean, it's not necessarily that if you have n equations with n variables, then the system will have one and only one solution. It might not have it at all, etc. But, however, generally speaking, you should expect for n variables, which are known to you to have n conditions, because every condition might allow you to find one particular extra variable. So, you can just reduce the number of variables from n down to 1. And then, number of equations can be used for this purpose. And that's how you can solve the whole system of equations. Again, not necessarily true. There are systems of n equations with n variables which have no solutions, one single solution, k solutions, or infinite number of solutions. Everything happened. But in general, you should really expect that the number of equations and the number of variables correspond to each other. Okay. So, this is just a general definition of the system of equations. Now, the solution is if you find some set of values which being substituted into each one of these results in corresponding number of identities, all n should be numerical identities. If it is possible, then these a1, etc. an represent a solution. It might not exist at all. It might be only one unique set of values, or it may be two or three or k sets of values. It can be infinite number of values, but all of them are solutions. All right. Now, it's time to give you a few examples. So, I would like to give some examples of the systems which have no solutions, one solution, two solutions, whatever. That probably would help. All right. If we are talking about system of equations, by the way, I didn't really say it before, let me say it now. Question is what kind of values are unknown can take? So, basically, if you wish, where exactly we are looking for solutions? We can look among integer numbers, we can look among positive numbers, we can look among all real numbers, we can look among complex numbers, etc. So, whenever the system of equations is specified, it must also be specified what exactly is the set of values where we are looking for solutions. Now, if nothing is said about this, traditionally it means we are looking for real number solutions. Everything else, like if we are looking for complex solutions or we are looking for integer solutions or whatever else, is specified. It mustn't be specified. Because, again, traditionally, by default, if you wish, we are always looking for real number solutions. Okay. Now, I will assume exactly this. I will assume that we are looking for real number solutions unless specifically set otherwise. So, let me give an example of a few systems which have certain number of solutions. Okay. One, two. Okay. This is the system of two equations with two unknown variables, x and y. So, my question is what are the solutions of the system? The answer is there is none. Now, why there is no solutions? And, again, we are talking about real number solutions. Well, look at this. x square plus y square. x and y are real number. Positive, negative doesn't really matter. But x square and y square are always positive or zero, right? Now, can it be positive? No, because the sum will not be equal to zero. If the sum is equal to zero, it means each one of them is equal to zero. So, x is equal to zero and y is equal to zero. We basically get the value of various of our unknown variables, x and y, right from the first equation. As you see in this particular case, it's sufficient to have one equation with two variables, but it's such a specific type of equation that we can get the values without any other conditions. But now I have the second condition, that their product must be equal to one. Well, obviously, these are zero and zero, the product will not be equal to one. So, the second condition will never be satisfied if the first is satisfied, which means the system has no solutions, all right? No solutions. Okay, next. Next, I have an example with one solution. x plus y plus z is equal to 6. 2x plus y plus z is equal to 7. And 3x plus y plus 5z is equal to 20. All right. Now, in this particular case, this is an example of a system which has one and only one solution. Now, how can I find out this particular solution? Well, in this case, it's really easy. Let's do it this way, since if x and y and z are solutions, which means all these three equations are actually identities. Now, we can subtract from the second one, we can subtract the first one, and what do we see? y and z would nullify each other, so x and x, if I subtract from this, I subtract this, I will have only one x here, and 7 minus 6 would be 1. So immediately, I see that the x is equal to 1. The necessity of these two equations actually results in one and only one value for the x. Now, if I have that, I can always transfer my system of three equations into a system of two equations, namely, I will take this one, and instead of x, I will use 1, which means y plus z is equal to 5. y plus z, this is 1, this is 6. So y plus z is equal to 5. And from this, the third one, 3x is 3. So y plus 5z is equal to 321, so it's 17, right? So now, if I will subtract this one from this, I will get 4z is equal to 12, and z is equal to 3. Now, if z is equal to 3, then y is equal to 2. So I have basically solved, and we're not talking about how I solved it, it doesn't really matter, but I came to a conclusion that from these, necessary to have these three as values. Now you can obviously check and everything will work out. So this is just an example of a system of three equations, linear, by the way, because everything is in the first degree of power, which has only one solution. Now, next is, I want multiple solutions. x squared plus y is equal to 3, and x squared minus y is equal to minus y. Alright, this is the system of two equations with two variables. Again, solving this system very easy. I will add them up, and I will have what? 2x squared is equal to 2, 3 and minus 1, y and minus 1, minus y will nullify each other, from which x squared is equal to 1, from which x is equal to either 1, or minus 1, right? To get x squared is equal to equal to 1. Now, knowing two different values of x, I obviously have two different values of y, or maybe the same one, but it will be two different pairs. In both cases, x squared is equal to 1, so 1 plus something is equal to 3, that something must be equal to 2, right? And the same thing would be here. If this is 1 minus y is equal to minus 1, so y is equal to 2, the same thing. So I have two different pairs, two different solutions, one pair and another pair. So this is the case when one particular system of two equations with two variables has two different solutions, one solution and another solution. Okay, and finally, I wanted to give you an example when I have infinite number of solutions. Infinite number of solutions. x plus y plus z is equal to 6, 2x plus y plus z is equal to 7. What can we say about this? This is the system of two equations with three different unknowns. Let's just do it this way. If I will assign a new variable, y plus z is equal to t, then I will have x plus t is equal to 6 and 2x plus t is equal to 7. Subtracting from this, this, I will get x is equal to 1 and t is equal to 5. But t is y plus z, which means any combination of y and z, which sounds at 5, basically would satisfy this particular equation. So I have an infinite number of solutions. 1, then if z is equal to 0, for instance, y is equal to 5. So it's 5, 0. 1, for x it's still 1. Then if z is equal to 1 and y is equal to 4, 4, 1. This is also a solution. 1, 3, 2. And now I'm talking about the integer solution. So obviously there are all kinds of real number solutions. So anything, whatever z is, if y is equal to 5 minus z and z is anything, that's a solution. So all these triplets, when the x is equal to 1, z is anything, and y is equal to 5 minus z, all of these would satisfy this system of two equations with three unknowns as a solution. So this is basically an example of a system which has infinite number of solutions. And by the way, notice that this is a system with two equations with three unknowns. So it's again typical, again not necessarily, but it's typical that if number of equations is less than the number of unknowns, you might expect something like infinite number of solutions. Again, not necessarily because as I was saying, something like x squared plus y squared is equal to 0, this particular one equation with two unknowns has only one solution, x is equal to 0 and y is equal to 0. That's it. However, in most of the cases, you can expect that if number of equations is less than the number of unknowns, you might expect a lot of different solutions, maybe infinite. And now I will talk about something which I did touch before, a system of equations when one equation is derived from others. Let's just consider one of them. x plus y plus z minus 6 is equal to 0, 2x plus y plus z minus 7 equals to 0 and 3x plus 2y plus 2z minus 13 is equal to 0. Alright, we did actually mention this system of equations before. The only thing was I put 6 and 7 and 13 on the right. It doesn't really matter. So anyway, what's peculiar about this particular system of equations depends on the third one can be derived by the previous two by adding them together. You see, x plus x, 3x, y plus y, 2y, z plus z, 2, z minus 6 minus 7 minus 13. Excuse me. And as I was saying before, this is a case when the third equation doesn't really bring us any new information. So in theory, if anything satisfies the first two, it will definitely satisfy the third equation as well. So as if I don't have it, basically that's what it is. So this case is called a derived equation, derived from the previous ones in this particular case. And the system becomes basically under-determined. So you have less conditions than the number of variables and it's so much less that it results in the number of variables to have indefinite number of solutions, infinite number of solutions. All right. Now, what's very important about derived equations is, well, let's try to formalize it somehow. So let's go back into the original general form of the system of equations. Now, general form, as I was saying before, was some function of N variables is equal to zero, then another function, etc., and then function number N from the same. Now, what does it mean that the system is really containing certain equations derived from others? Well, derived how derived? I mean, that's not easy to define, right? Okay, here is something which I consider to be a decent definition. Let me just, for definitiveness, talk about derivation of the last one, f nth function, or equation actually, from the previous one. What does it mean that f nth of this, the nth equation, is derived from the previous m-1 equations? It means the following, that the function itself can be derived from the previous functions using some derivation function, f, which is supposed to be known, f1, 2, m-1. Where these are x1, x2, xn, x1, x2, xn, x1, x2, xn, etc. So, if my mth function can be expressed as algebraic function f, known function, from the other m-1 functions, that actually means that it's derived, and it means that basically it doesn't bring us any new information. The only thing which is really important in this case is that if x1, etc., xn are solutions, then this is equal to 0. Each of these is also equal to 0, which means that I should have the equation 0 is equal to f of 0, etc., 0, as a necessary condition for this derivation. So, what does it mean that the mth function is derived from the previous one? The mth's equation is derived from the previous one. It means that the function itself, fm, can be expressed as a function of functions, in this case, and there is this condition which function f must actually satisfy. Well, let's just go back to our original example and figure out what exactly... I don't need this anymore... what exactly I mean in this case. If I have these three equations as before, let me do it the way how I did it before, everything on the left, and 0 on the right. Okay. Now, as I was saying before, the third equation is a sum of these two. What does it mean? It means that our function f of two variables, only two, should be equal to u plus v.  So the functions are related using this particular form of our derivation function. So f of uv is equal to u plus v is a derivation function. And the way how it's derived, basically I've just described. Now, let's check the second condition, this one. Well, indeed, if I will put 0 and 0 instead of u and v, I will have 0 plus 0, which is 0. So function really satisfies this particular condition. Now, what if this particular condition, f of 0, 0, 0 equals to 0, is not satisfied? Well, let me give you another example. Let's just assume that instead of these two, these three equations, rather, I have something slightly different. Instead of 13, I will have, let's say, minus fiction. Now, can I find a function which will connect these two to this one? Well, yes, indeed.  So, I have found my function. This is my function, which is a derivation function which allows me to derive the third equation from the first two. However, how about this condition? Not at all. If I put 0 and 0, I will get 0, 0, 0 plus 0 minus 37. So, this condition is not satisfied, which means that derivation, I derive the left parts of these equations, but I cannot derive the right parts. 0 will not be derived in the same way as the unknown. So, basically, what it means is that the third is not really properly derived from the previous two. Basically, that's it for introduction. I just wanted to talk about certain terminology, about general concepts of what real systems of equations are, and I didn't really touch any specific types of the systems, like systems of equations of the first degree, linear system of equations, second degree or polynomial system of equations, logarithmic, whatever. This is the subject of subsequent lectures. But as a general introduction, I do recommend you to go again back into the Unizor.com notes for this particular lecture. Read it again. It's always helpful. Thanks very much.
