So we're doing homework from lesson seven, orbital mechanics. We're doing example 3A. And now, circular force. Again, Aaron, don't forget the mass. Because the formula, the equation for acceleration, is so complicated, kids forget you've got to put an M in front of it for force. Which one do I want to use? Darn right. Oh, as it turns out, the little mass cancels. And one of the R's cancels. And in fact, I get orbital velocity is equal to the square root of 2. Not 2, Mr. Dewick. You're doing the wrong question. Good gosh. The square root of big G, big M over R, where M is not the mass of the Earth this time. It's going to be, we're talking about the mass of the moon, which I think is on your formula sheet. I have no idea what it is. Did you get this far? OK, because it says from the moon's center, that is a radius. R is going to be 2.5 times 10 to the sixth. By the way, once you have velocity, can you do b orbital kinetic energy? Yeah, kinetic energy is a half M v squared. In fact, what we noticed last day, it was a half M big G, big M over R. Because v squared was big G, big M over R. That's kind of a nice coincidence. I said, Dan, you don't need to memorize that, but it's kind of nearly cool. Orbital potential energy, that's going to be negative big G, big M over R. And the total orbit energy is going to be the potential plus the kinetic. And I think it's going to end up being half of the kinetic but positive if we do it right. We're doing the moon for starters. But it says it ends up orbiting 2,500 kilometers from the moon's center. What is the radius of the moon? Radius of the moon can't be times 10 to the eighth, because the Earth is 10 to the sixth. And it's not bigger than 1.74 times 10 to the sixth. Yeah, so it is above the moon. 2.5 times 10 to the sixth means it's orbiting above the moon somewhere. Be prepared. I mean, most of what we've done is with the Earth. So think about the questions that you've answered. An easy way for me to give you the same question, but different numbers, is to make up an imaginary planet and give you a different mass and a different planetary radius. So Earth, we've used quite a bit. Moon would be a good one. I'll move some of the stuff to the moon, same question. Or I think on your final exam, I think I'd put a planet do it with a radius of pi and a mass of E or something like that. If you're really alert, you might notice that. But what a great planet. Something like that. I think it's like 3.14 times 10 to the eighth or something like that. Well, it'd be a nerdly cool planet in my mind, but that's OK. Any others? So today is kind of wrapping everything up. I have a take-home quiz for you guys first, though. So if you take a look at the take-home quiz, the take-home quiz has no gravitation stuff on it. It's actually lessons 1, 2, and 3, where we looked at the kinematics of circular motion, horizontal, and vertical circles. I'll have a take-home quiz for you also on next class. And that's going to be on all the gravitation stuff. And what we're going to be doing today, lesson 8, is looking at some neat examples that combine energy and circular motion and other concepts, problems involving circular motion and other concepts. Example 1, roller coaster loops are a great example. Now, again, this is in our magic physics world, where everything works perfectly. In real life, roller coaster loops are not circular. If they made them circular, we'd black out. The G forces are tremendous. They're what's called a clothoid loop, or a clothoid loop, or a clothoid loop. I don't know how you pronounce it. I've never heard it pronounced. But it's a teardrop shape. If you look at a roller coaster loop from the side, it's not a true circle. It's a teardrop shape, which means the radius is constantly decreasing, which is why you don't black out when you go over them. But we're going to be in our magic physics world, or when we're going to have nice circular loops that we can analyze. And it says this. Pardon me? G forces. The blood wants to continue going in a straight line, but your body's being forced in a different direction. Same reasons why pilots would black out. So example one. At the top of a 12, it says centimeter. Oh, yes, we're using a little toy car. Radius loop. The 350 gram toy car experiences a force from the track of two newtons. Assuming that the car is released from rest and that the track is frictionless, find how high it was released from. And the range it travels after leaving the ramp. So I don't know about you. I don't know if they're still made. When I was a little kid, I played with the little matchbox cars, and we bought the plastic race car track set that you fit together with the little purple or whatever.  They're orange. You got the little loop kit with it as well. Some of you're nodding your head. Some of you have seen this stuff. Talking about that. What do they want us to find? It's release height. Is there a change in height between here and here? I think the best way to solve this is going to be energy. I'm going to start out solving this. And also because this isn't a nice straight track. It's a curvy track with loops and stuff. I'd like to use a scalar rather than a kinematics forces projectile approach. I'm going to start out by going kinetic energy initial and potential energy initial equals kinetic energy final plus potential energy final. Now we need to talk about what I mean as initial and final. I'm going to talk about this right here as location A and right here as location B. And I'm going to say location A is initial, location B is final. I'm not talking about the top of the ramp right now. And the reason is they gave me information at the top of the loop. So I'm going to use that. Are any of these zero? Does say starts from rest. Am I on the ground right here? Nope. Am I on the ground right here? Nope. Am I stopped right there? No. Yes. So none of these are zero. Now I'm going to oh, they want me to find the release height h, which I think is going to be initial height. So I'm going to just expand this. mgh initial equals a half mv initial squared plus mgh, sorry, not initial, final squared and final. mgh initial equals a half mv final squared plus mgh final. E and I do notice they didn't need to tell me how much the car weighed, which is kind of nice. And I guess to get the h by itself, I'll eventually just end up dividing by g. I'll come back to that. Let's walk down this. Do I know the final height? Well, if the height, if the loop has a radius of 0.12 meters, 12 centimeters, how far from here to here? 12. How far from here to the top? 12. How far from here to the bottom? What's the total height? 0.24, 24 centimeters. So I know that. Do I know g? Yep. Do I know v at the top? Well, I don't know it. So I'm going to write a little note to myself here. Need v final. Ah, but here's the key. What path is this car traveling in? Circle. I'm going to solve this. I'll just flip her there for a second. OK. Stay alive, bulb. Just last me till the end of the year, please. I've got you budgeted for next year, but not for this year. It's cheaper to buy a new projector, $600. I'm going to solve this using circular motion. So I'm going to make a little note here at top of loop. What are the forces acting on this car at the top of the loop? Get the obvious ones. Get the obvious ones. Gravity. And there is a normal force. Am I on the inside, or am I on the outside of the loop? Inside, so which way is the normal force? Also downwards. I wrote mv for some reason, mg. Let's try that again, Mr. Dewick. Don't try and do five steps ahead, Mr. Dewick. Just do this right. What path is this traveling in? A circle. Where must my net force be toward the? They're both toward the center. They're both winners. My equation's going to look like this. mg plus fn equals, what am I right here that I wanted to? Yeah, fc, absolutely. Except which fc am I going to use, the one with the period or the one with the v in it? I'm going to get this. mg plus fn equals mv squared over r. If I want to get the v by itself, I think it's going to be times everything by r. You know what, this is yucky and complicated. I'm just going to give up and start sticking in some numbers, I think. The mass, OK, now this time the masses don't cancel. Says the masses, 350 grams is 0.35. That's a heavy car. 0.35, that's about a half pound. That's a heavy car. 9.8 plus, what's the normal force? 2. By the way, what if I wanted to figure out, or what if I told you that it just barely made it over the loop? What would the normal force be if it just barely made it through? 0, so we can later on, we'll calculate minimum height required for safety. 2 equals 0.35 over 0.24 v squared. 0.35 times 9.8 plus 2. I get, oh, that's for an r, not a height. You're right. Thank you, Irwin. Sloppy me. It says r, which is 0.12. I agree. The left side, though, does work to 5.43, I think. Does it not? I hope. So we get this. 5.43 equals 0.35 v squared all over 0.12. How would I get the v by itself? What would I do with the 0.35? Divide, what would I do with 0.12? Times, and how to get rid of squared. I'm running out of room on a test, I'd show that. But since we're running out of room, I'm going to go straight to my calculator here. So you guys said I would times by 0.12, divide by 0.35, and then square root that. And I get a velocity of 1.364. And since that's not my final answer, I'll carry an extra sig figure 2. So I'll go v equals 1.364. And that's v final. And now I'll plug that back into there by 0.12. Yeah, you can go that, divide it by that, and then move it over. Yeah, let's see if we can get h initial then. So h initial is going to be a half, that's 0.5, 1.364 squared. I'll use the number I still got on my calculator, plus 9.8 times. What's the final height? That we said was 0.24, two radiuses, two radii. And to get the h by itself over here, yes, Taylor, divide by 9. I divide by g, right, 9.8. OK, 0.5 times that answer squared plus 9.8 times 0.24, enter, and then divide that by 9.8. Minimum height, 0.335 meters, 33 and a half centimeters, 0.335 meters. Now part b is nerdily cool, but we're not going to do it in the interests of time, although I kind of like it. Part b says, find the range. To do that, you would have to find the speed at the top. You could do that repeating what we've done here with energies, but instead, you're trying to again find v final, but you're not worried about the loop. Your h initial would be 0.335. You could get the speed right at the very, very tippy top of this. It's your final height is 6 centimeters, and you would have an angle of 30 degrees, and we'd have a lovely projectile question. But in the interests of time, I'm going to pass. Yeah. No, otherwise, I'd do it. OK. Example 2. A satellite in orbit around Earth, is that right? So you know what we should do, though? I guess, Aaron, to be clear for people that are away. So I'm going to go, nice question, but pass part b, right? The math nerd wants to do it, but I want to get you guys going on the homework. Example 2. Satellite in orbit around the Earth is at radius big R and speed little v. Satellite is hit by a small rock, and it slows down somewhat. What happens to the radius of its orbit? And it says, assume the satellite begins and ends in a circular orbit. I think what this is asking is, how are your orbital speed and your radius related? You say that again. How are your orbital speed and your radius related? And the fact that I said orbital speed and radius in the same sentence says to me that if I want to somehow prove what's going on, I'm going to start out by going, I don't know, we're going to convince ourselves. Gravity never changes.  Which FC do I want to use, the one with the period or the one with the velocity? We're trying to figure out how radius and speed relate. I'm going to use the m v squared over R. M cancels. One of my R's cancels. And I want to get the R by itself. I want to ask myself, when I get the R by itself, I'm going to say, OK, if the v gets bigger, will my R be bigger or smaller? So if I get the R by itself, let's see. It's on the bottom. It would move on the top over here. In fact, I think I get this.  Is that right? Is the v on the top or on the bottom? Bottom. So as v gets bigger, what happens to the orbital radius? It gets smaller. In fact, we said to orbit around the Earth's surface, we did that question. You'd have to be going really fast, because your orbital radius would be as small as it could be. As v gets smaller, your orbital radius gets bigger. So if you're going to end up in a stable orbit, because you got into a collision and slowed down, you'd have to end up further away from the Earth. And you'd need a very nice coincidental meteorite that struck this object at just the right angle to send it further away from the Earth and magically give you just the right orbital. This is a theoretical question, in other words. But yeah, as it turns out, final orbit would have a radius smaller than r. It says, explain your answer. I would write this, but I didn't want to write this down here. I wrote my equations up here. And then I would simply say this. As v decreases, r decreases, except Troy on the test. I probably write the word decreases and decreases instead of down arrow and down arrow. Sorry. As v decreases, r increases. That's what I said. Let me make that arrow a little clearer so you can read it properly. Sorry. Sorry. Isn't it ii? Slump. As this number gets smaller, this number gets bigger because we're dividing by a smaller number. And in fact, if this is twice as small, four times as big, I think, because it's an inverse square thing that we've talked about as well. What that means is the further a satellite is away, the less kinetic energy it has to have. Oh, but the more potential energy you have to burn to get it there. So somewhere, there's a magic, good, best, best efficiency zone where you're getting your best bang for your buck. Little technical comment, according to the author, the final orbit is actually not quite a circle. It's an ellipse that passes through the collision point and then moves closer to the Earth on the far side of the orbit. In other words, don't write this down, but it would look much more like that where you're a little closer here and a little further there. Next page. Aaron, do you remember you asked me a question a little while ago on the test? I like this question. I like this question. And specifically, the concept that I like is that part there. Barely makes it around. Now, they want us to find the normal force, so we're going to have to do a good free body diagram here. The problem is in our free body diagram, I think what we have to start out doing is we need to figure out this initial height so that we know how fast he's traveling down there or she's traveling down there. And I'll convince you of that in just a second. So we're going to start out. It says, find the normal force at the bottom. So I'm going to say this. At bottom, what are the forces acting on this roller coaster? Get the obvious ones. Gravity down. What else? Normal force up. Why did I draw normal force so much bigger? What path is this roller coaster tracing out? A circle. Where must the net force be then toward the center? Normal force has to be winning. Until he levels out, normal force has to be winning. So we would have this.  Do I know the mass? I think they said 50 kilograms. We're going to ignore the weight of the roller coaster. We'll just look at the weight of the passenger. Do I know g? Sure, 9.8. Do I know the mass? Yep. Do I know the radius? 4 meters. What I don't know is the speed at the bottom. I don't think it would be 0 because that would mean you'd come to a stop. I don't think you'd come to a stop suddenly. You keep going. Do you not? I don't think the speed is 0 at the top because if it was 0 at the top, you'd come crashing down and die. But here's what we're going to have to do, I think. We're going to have to, because we don't know v at the bottom, we're going to have to now go to some energy here. We're going to have to go to top of loop. At the top of the loop, what are the forces acting on this person? Get the obvious ones. mg. Now there is a normal force down, except because I said just barely makes it around, what do I want the normal force to be? That's what I want to be 0, not the velocity. I want them to feel like they're just about to fall, but they're still safe. So I'm going to say at the top, mg equals mv squared over r. v squared at the top is grr. grr. Oh, mass cancels. Now how does that help me? So we looked at the bottom and we said, really, we need to find out how fast he's traveling at the bottom. Well, to find out how fast he's traveling at the bottom, if I know how high he is here, all the potential is going to at the bottom be totally kinetic. So over here where I wrote at the bottom, put a little comma if you have room off to the right, we're also going to say this. Potential energy initial is all going to be kinetic energy final. Mgh initial is going to be a half mv final squared. And yes, Evan, once again, yay, mass cancels. For me to find the velocity at the bottom, which I can then plug in here, I think, I need to find my initial height. I need to find my initial height. How can I? Sorry? Well, if I divide by g, I still don't know v, though. If I know this, I got that. I got this. So what I need to find is this. Well, let's look at the top of the loop. Let's call this here location A at the top of the hill. And let's call this here location C. I'll call the bottom location B, B for bottom, so that gives me an easy way to remember this. Seems to me we can say this. The kinetic energy at A and the potential energy at A has to equal the kinetic energy at C plus the potential energy at C. However much energy you got at the top of the hill, that's how much you got at the top of the loop. Now, I think we are starting from rest, so I can safely say that. But the rest I'm going to expand. This is going to be mghA equals 1.5 mvC squared plus mghC. Yay, mass cancels. We're going to get this. ghA, initial height, is equal to 1.5. Now, this is the velocity at the top of the circle, which I don't know, except I have an expression for the velocity at the top of the circle. What is v squared the same as? Grr. So I'm going to write 1.5 grr, OK? And if you have a bit of patience, something nerdily cool, and it is only nerdily cool, is going to happen. Plus, now look up, please, all of you. This is height C. But from here to here, how many radiuses, how many radii is that? So instead of writing hC, as I notice I have an r right here, I'm going to write g times 2r. What happens to the g's? So this is kind of unusual. Now, what this is telling you, Brandon, is if you could somehow transport, using like a Star Trek teleporter, this roller coaster to the moon, you wouldn't have to change any of the heights. It would work just fine. Or if you could beam it to Mars, or Jupiter, or wherever, anywhere in the universe, this roller coaster would work just fine no matter what planet you were on. The gravitational field, as it turns out, completely cancels, which is kind of nice. Oh, so I now have this. The height to start out with is 0.5 1⁄2r plus 2r. I think those are like terms, aren't they? What's 1⁄2r plus 2r? 2.5r. And this is what I wanted to show you guys. When you're designing any roller coaster, and it has a loop, the minimum safe height is 2.5 times the radius. If you build the roller coaster hill, 2.5 times the radius of your bigger loop, your biggest loop, they'll make it through just barely if we ignore friction. So of course, you build a huge safety margin in. But I love, Evan, the fact that starting with this mess, we get such a clean answer as I've ever given you all year long. I mean, even gravity canceled. I don't think that's ever happened before. So the math nerd within me, the physics nerd within me, says, it's kind of cool, actually. And I'm willing to bet most amusement park ride designers know this. Now, this is for a circular loop. I don't know what it is for a clothoid teardrop shaped loop. I suspect it's different, probably considerably less. But this will just barely get you around. Now, what the heck were we trying to find? We were trying to find how fast you were going at the bottom. And we said, I think we can solve this using energies. Using energies. And once we find how fast we're going, we can find the normal force over here. So are you ready? I'm going to go like this.  Right, Brandon? Because you're carefully writing this down. I don't know where you were, but I don't think you were. By the way, Brandon, what's 2 times 2.5, folks? Careful. 2 times 2.5, not 10. 5. Can I write this then? I think v squared equals 5 gr. What does this question ask us to find the normal force at the bottom? We started out by writing the normal force equation. Troy, how would I get the normal force by itself? OK. So now we're going to take this over here. We're going to get this. Normal force equals mv squared over r plus mg. But what's v squared the same as? 5 gr. The normal force this person is going to feel is going to be m 5 gr. We took care of the squared because we plugged in an expression for v squared over r plus mg. Holy smokes, what happens to the r's? And in fact, here's what I have. 5 mg's plus 1 mg. This person's going to feel six times their weight at the bottom. That's also, I like this question, and it's a nice, clean answer, Erin, kind of like, wow. I expected yucky decimals and junk and holy smokes. As it turns out, final answer, the normal force is going to be 6 mg, which is going to be six times, was it 50? Is that what I said the mass was? Six times 50 times 9.8. They're going to feel 2,940 newtons.  Well, I don't. I do and I don't. I like this concept here. And I like this concept to get the 2.5 r. In fact, you're going to find on your take home quiz, there's a question where I say to you, a roller coaster just barely makes it through how high it is the first hill have to be. I think that's a fair game question. The rest of this asking you to extend it to the normal force and find all that, I did because it was nearly cool. I don't know if I, in fact, I know I would not feel comfortable asking that. Not on a written section and even as a multiple choice, that's a little tough in my mind. Yeah. How many genes can a human body handle? It depends on the circumstance. Most of you could handle for a short while. First of all, it depends on whether it's positive genes or negative genes.  That's when you black out.  We don't deal with that as well in terms of physical issues, but we won't black out.  The answer to your question, there was a test pilot in the 50s who, the US military, to test their ejection seats. How do you test ejection seats on the ground? Out in Nevada, they have a rocket sled track where they would basically strap a guy to the front of this and slam this rocket sled into a cargo net. And he was hitting, I believe, around 200 or 300 Gs, but he was also, his blood vessels in his eyes would pop and he'd have bruises everywhere. Like it was, they wanted to find out what someone could survive and recover from in a few weeks. And the answer seems to be in certain situations and those were straight on G horses, not positive or negative. We're pretty robust. I suspect this here, you'd be very, very sore. I know the original roller coasters that they built with loops back in the 1910s and 1920s, they built them with circular loops, not knowing any better. And I think the Coney Island one, they had a permanent ambulance station there. And it was a regular thing. You would go through the loop to loop and you would get nosebleeds. That was the big one. I got nosebleed, I didn't bleed at all. Oh, you know, that kind of thing. And it wasn't until Six Flags in California, I think, in late 60s, early 70s, they were the ones who realized, don't do a circular loop. So they were the first ones to do a successful and safe roller coaster loop. Yeah, you either do what's called a clothoid loop or you do a corkscrew. In a corkscrew, what you're doing is you're keeping your head as close to, or your heart really, as close to the center of the radius as possible. So your head and your heart are not undergoing very much circular force because our are small. Your body is rotating around, but you don't really care if your feet aren't getting the blood that they would like. They don't seem to be complaining too much. So you've seen the Playland, the Playland one has a corkscrew, right? Does it have a, yeah, does it have a regular loop too? I don't think it does. No. How many of you've been on California screaming at Disney? Okay, so that's a clothoid loop.  You will not be able to. I mean, you can really try, you will not be able to. The G-forces won't let you, okay? So, oh, and raise your right hand. All of you, all of you right now, everybody raise your right hand, repeat after me. I promise not to sue Mr. Dewick. Thank you. I just had horrible images of, I'm gonna try standing up. No. Okay. Homework, number one. Homework, number one. Number four. Number five, please notice in number five. I think we're talking about the earth in number five, it doesn't say, but we're talking about the earth. And please notice they gave you an altitude, not a radius, and it's in kilometers. Six is also good, find the gravitational force. Seven is also good, find the strength of the gravitational field. And number eight, this is where you're finding the minimum speed that it has to have at the top of the loop and the height from which it must be released. So that you can try as well. A nine B, that's all lovely review, but I'm gonna pass there. And we're officially done circular motion. What else are you working on today? Cause it's a shorter lesson. Take home quiz, and you have the great big circular motion review thingy. That answer key is online, and that will be due the day of the test. And your test is not gonna be this week, it's gonna be probably towards the middle end of next week. I think I said right now, I'm looking at Wednesday. Yes, if you happen to have it remembered and you use it, I'll clue in. You've already, you've had me long enough to know I despise in my mind memorizing things that I can derive in two seconds. But that one was about a 10 second derivation. I might, I guess. It's a nice, no, 2.5 times the radius. Okay, fair enough. I mean, certainly for number eight, you can use 2.5, but I would practice deriving it on number eight just to see if you can. It's gonna be 2.5 times the radius. Oh, 10 radius, 2.5 times 10, 25 meters. Oh, there's the answer. I don't want you to just go like that, right? Okay, let me hit stop. Oh, nope, let me hit stop.

You can't Google these.  So for $75, I'm gonna give away at least 500 bucks. We'll do this on Venmo or Bitcoin, your Tooch or ETH. You're gonna have crypto or Venmo. The second question is, if we go back in history, we go back in history, who was the first trillionaire in modern times? The last 500 years. The first trillionaire, first and last names only. All right, I'm gonna look down for a second, give everybody a second to go. I have 500 people on Instagram. We got, there's over a thousand people on all the different platforms watching. Sometimes people on Twitter are like, there's not many people on here. I'm like, that's cause they're on Instagram. I'm not a big Twitter guy yet. Been my least. Now that Elon bought it all, do my. Somebody said Putin, nope. And I said first and last name, so you fail. This is like Jeopardy, Movo. You gotta say it right. Jeopardy, you gotta say, is that Vladimir Putin? Nope. I said the first trillionaire in the last 500 years. Nope, not Rockefeller. Who was worth about 600 billion? Nope. There's a lot of notes happening right now. A lot. If you don't know history, you're, if you don't know the failures of history and the success of history, you're doomed to repeat the failures. So you gotta know history. Someone said Musa Monsa. I think that Musa Monsa, wasn't he more than 500 years ago? I've read he was the wealthiest guy. Let's do the last 300 years. I don't know about Musa Monsa. I should.  So it doesn't teach you anything about African history. It's crazy. America only teaches you. Every country teaches their own version of history. I was talking about Russian friend. They teach that Stalin is the one who won World War II, because remember it's the Russian generals that went into Berlin.  Russians won World War II in America. You learned it in Americans in English. You learned it in English, in France, it was the French. In America, we don't learn anything about Africa.  Even though Africa has a big part in history. Somebody asked if I'm wearing a wig. Ewan, you fail.  And why would you care?   He's like, get out of the good information I can get from people. So for this one I'll pick, let's pick TikTok. No, let's pick Instagram. Let's give Rick, look for the anybody pin them that said Napoleon owned a part. That was the first trillionaire. Easily, he was probably worth, I mean, he controlled Western Europe. So he was probably a decade trillionaire. The current global net worth is 300 trillion is the estimated net worth of the world counting real estate. Okay, about 200 trillion is real estate. About 100 trillion is the economy. Okay, so we said Mark Cuban, no. So when you have a military like Napoleon Bonaparte, and remember, he conquered all the way to Moscow. He's the only modern general to actually take Moscow. Hitler failed trying to take, Moscow's a hard place to take. It's cold and the Russians burn everything if you go into there. So he controlled the whole Western world for about a decade. That makes you a decade trillionaire. So y'all should know that. I don't teach that in school. I don't teach that in school. Okay, next. So we're at $75, let's go to 100. Someone said Babylonian families. Do you know what 500 years is? You think Babylonia was in the last 500 years?  I feel bad for you. You got to drop out of it. Drop out of the system. Babylonia was in the BC times. We're talking thousands of years ago. Sometimes I get confused and worried about modern society. Okay, okay. Next, money making trivia. We're at $100. Did you pin the Instagram person, Rick? Well, I won't let you pin. What happens when you tap on it? I can only post comments on it myself. Are you on, no, you tap on it and hold it down. Okay, let's go to $100 giveaway. Money making. Let's do more modern times. Okay. What is an acquisition that happened, I believe, between 2005, what's the most important acquisition in modern business money making history? The company bought another company. Important one purchase. What did they buy? Who bought who? Between 2005 and 2009. I'll give you a wide range. Facebook about Instagram, Nicholas says, no, that was I believe in 2012. You're off by many years. Let's pick somebody on. Let's pick a TikToker here, Rick. Can you take a picture for $100? Now, everybody, I'm gonna do the big giveaway on my private Zoom, because I've gotten banned off TikTok before and stuff like that. So everybody should be, please move over to TylerBus.com slash Zoom. If you wanna win the big big prizes when I'm going up, it's only gonna be on my private Zoom right here. So all you gotta do is go to TylerBus.com slash Zoom. No credit card needed, no money needed. Somebody said, bite Nance buys musically. That is in about 2017.  Elon but Tesla, that's 2004, approximately. He did multiple rounds. PayPal, nope, that was like 2001 or two. Y'all gotta know history. Those who don't know history are doomed to repeat the failures of history. So let's pick someone on TikTok. It's not the first one that wins. By the way, I'm getting ready to go to the large dollar numbers. You should be getting off Instagram, TikTok, TylerBus.com slash Zoom. Go here. All right. Somebody just wrote Queen Elizabeth. Yes, that is the answer, this person. Okay, there we go. Chris Araleno 986. I'm gonna pin the comment so you'll see it. Chris Araleno, damn it. Now we gotta go up and find it because there is Chris Araleno 986. Will DM you from my TikTok, you went $100. Google bought YouTube. These guys right here made a genius acquisition, genius. I think it was about a billion dollar transaction and they bought YouTube. Guess what the two biggest search engines in the world now are? Number one is what? Google, these two dudes own it. What's number two search engine in the world? Not Bing, not Bing, not Bing. This guy started Bing. I know him, but Bing has not been a great success. Does anybody Bing it?  Can you Bing it? I could have told whoever they hired to do the name Bing should be tarred and feather. I used to pour tar on people and then do feather. Bing, that's not a good name. It sounds like a disease or something. I kind of don't feel good, my stomach is binging.  This is not a good name. So these two dudes own Google, which is that two syllable bang bang is a little bit better, you know? Twitter is a pretty solid name. Facebook is a pretty good name. Google Bing is not good. That one syllable sounds almost like your, I don't know, sounds like a camel spit. You ever seen camel spit on people?  Okay, so these two dudes control all search for the world. These are like modern, massive. These are the oligarch monarchs of the world because if you control search, you control the flow of information. And now probably almost going to become the third biggest search engine. It's not there yet, it's going to be TikTok. TikTok has a much better search. This guy is one of the great entrepreneurs for sure, but the search on Instagram, I don't know if he hired some intern.   Can you build our Instagram search? Instagram search, you might as well fucking, you can't even search your friend. You can't even find your best friend. You know, Instagram search is just shitty. Twitter, TikTok search. I go to TikTok to find memes and stuff. It's even better than YouTube. So now you got these two dudes control search engine number one, number two. Search engine number three is owned by the damn Chinese. Who's fourth? Maybe DuckDuckGo is a new one? I don't know. Okay, all right, next. Let's go here. Somebody's still talking about Babylon. We got somebody, I don't know what plant this guy's on. We talked about Babylon like 10 minutes ago. All right, let's go. Next question. So how much have we given away? Marina, we've given away. 50, 75 and 100. So we're at 225. Somebody said 175. That's not a good math. Didn't we do 50, 75 and 100? So that's 175 plus 50 is 225. All right, now let's go. This person said they've said all bing it. Great. Next money making thing. Let's just jump up to 150 bucks. $150. Let's go. I'm gonna give this away on the Zoom. So if you're watching on somebody else's platform, TikTok, Insta, YouTube, Twitter, switch over to lopas.com slash Zoom. That's my private Zoom. I like people to be on. It's easier to give away the money too. It's half the time I can't find people.  You ever try to DM somebody on YouTube? Somehow YouTube did not get the message that people liked to DM.   It's an insane number. There are people that we can't even find after they win. I remember recently there was a girl on all this stuff. I was like, what's your Venmo? She's like, I don't like to use Venmo. I'm like, well, I'm the one giving the money out.  So, yes. By the way, I like controversy. I'm a controversial personal brand.  They're a saint. Don't follow me. Brands that are saintly brands.  They're virtue signal liars. All the people you think are virtuous, I know them behind the scenes. Well, I know the social media people you all look up to and you go, oh, that's the virtuous. That's the person who really cares about people. Oh, I know them behind the scene. They've been in my house. I know how their brain works. You'd be sadly disappointed. I like a little controversy. I'm glad some people go, does Ty really pay out? Oh, does Ty have a fake Lamborghini? I love it. People spread your name. All those of you building a personal brand. If you're boring, like Drake said, if you don't have haters, you ain't popping. Popping equals money making. If everybody loves you, you'll be right, but you'll be poor. Okay. I am Krishna Pathak.  I can't stop thinking about what you say. Well, good. All right. Next $150 giveaway. Money making. Let's not do history. Let's do right now, 2023, 2024. Super easy one. So Rick, be ready. This one's gonna go fast. Everybody should be using AI.  It's gonna change the world. It already has and it's just, there's gonna be lawyers will be replaced, accountants will be replaced, customer service will be replaced, realtors will be replaced, financial analysts will be replaced. Actively trading mutual funds will be replaced. Surgeons will be replaced, airline pilots will be replaced, Uber drivers will be replaced. Just get ready.  I've been calling trends on video since 2013. I have a not perfect track record of calling trends, but an insanely high one. Okay. You watch. It's gonna just change the game. Okay. So if you haven't bought into AI, thinking you're right, well, would you rather be right or would you rather be rich? Some of you would rather be right, not rich. You're like, I don't like the thought of AI. Therefore, I'm not gonna learn anything about it. Okay. Go for it. It's great. Less competition. Somebody said AI is not gonna get rid of surgeons. Bro, it already has. You haven't heard about robotic surgery? Where are you? That's like five to 10 years old. Did I say it's gonna get rid of every single surgeon? No. It already is. You haven't heard of robotic surgery, whereas robots going and making incisions. Did you ever get lasik surgery? Ever heard of lasik?  It's all a robot. It goes, I had it done. It's done. Shit, you want anything? I want some shaky mofo's hand who might sneeze while he's cutting my eye. Hello. Wake on up. This person was in 1942. In 1942, somebody would be like, robots ain't gonna replace surgery. Hello. Wake on up. Okay. So the simplest question to 150 bucks is my modeling support. When you ask chat GPT, which I still think is the best current AI in terms of for the public, I think it's better than being AI. It's better than Google's barred or whatever. What is it called? It's not called asking a question. It's called asking it a. It's called asking. Recording in progress. What is it called? What is it called? I'm back. It's super simple. I'm gonna look down. When I look up, we're gonna pick right here on my Zoom. You have to be on tylofus.com side of Zoom. So I'm gonna give everybody 60 seconds to move over. You're on Twitter or Facebook, YouTube. I don't care about my numbers on all of those. Lesson for all of you building a personal brand. Put everybody on your own internal Zoom where you have free speech. Repeat. I don't care about my numbers on Instagram. I'm trying to move everybody off my Instagram onto my private Zoom. I don't like to be on places that don't allow free speech. I want my own Zoom. Zoom doesn't care. I mean, if you did something crazy, move over to tylofus.com side of Zoom, it's free. I'm only, the big giveaway is right here.

All right, my team, you can pick the winner. One chat GBT. It's not called asking a question. It's called entering a blank for $150. We're going to break Zoom's chat here. One time I broke Snapchat. My Snapchat rep asked me not to do that anymore. In 2016, the inbox, it would go, it was insanity. When Snapchat first came out, man, it was crazy. Look at that Zoom. I got to, I got to take a video of this one. That's why I'm making my team go through that day. Hello, that doesn't look fun. Pick one winner randomly. Oh yeah, we're doing a giveaway. We're going to break that Zoom. If you're not on tylofus.com side of Zoom for this two day free webinar challenge, I've given away, this is something I would charge $2,000 or somebody put the word query. It is not query. Okay, $150. Have we picked a winner? Okay, everybody stopped. Wait, we can't pick anybody. Just stop, please. We can't pick anybody because my team doesn't have fingers that fast. All right, no new people go win. So you can stop, okay. There we go, stop, okay. If you want to win, because I'm going up now to $200 in a second. The answer is a prompt. It's not called asking ChatGPT a question. It's not called a search. It's called a prompt. Who won, it's a, okay. Who won. Okay, can that person, only that person, you're not going to trick us. Enter, put your Venmo right there. And then Rick, you got Venmo on your phone, right? That's Venmo, this person. So what does it mean? We'll do it from my phone. We're going to Venmo the person in front of everybody. You can watch Rick, my engineer, send the $150 for all of you people who say, does he really send it? I'm opening up my Venmo. Venmo, it's not a screenshot. Can you get it? Charger Rick is about to go. Going to my Venmo. What's, can you give me the name? It's all, what's their Venmo? I'm going to enter it. If you do not have a Venmo, pick another winner. Pick another winner, please. I think people have Venmo. Or you have a Bitcoin wallet.  Tip, I've got a little giveaway wallet that I use. Okay. Is it Reuben, this Reuben guy? Okay, Reuben, you're not going to trick us. We're not that dumb. Some people are like, oh, I'll just put my name in it. It's also not smart and she'll give me the money.  All right, let's go to the $200 giveaway. Only on TylerGuz.com's Live Zoom. Who wants to, who wants $200? Please have a Venmo or your Bitcoin wallet immediately ready. I want to show everybody that I'm going to give it to you. You cannot use Venmo in the Philippines, but you can use Bitcoin. That's why I like crypto. People say, oh, crypto doesn't have a use. I'm lying. Get with the program, man. You can do ETH too. I have a little giveaway wallet. It'll be public record. Everybody can see the transaction too. TylerGuz.com's Live Zoom. You shouldn't need a meeting name. It should take you right in here. Okay, let's go to the $200 question. 200-hour business trivia. Those who don't know the past are doomed to repeat the failures. Those who know the past will succeed in the future. So let's do something from the last 50 years, money-making trivia, things that are not easy to Google. Okay. Who's the winner, by the way? So what's their name? Peter Wallman. Okay, Peter Wallman. Says, one second, let me get my Bitcoin address. Good. Then you got to private message me because I ain't gonna be typing in Bitcoin wallet as a long string of letters. Okay, so $200 on TylerGuz.com's Live Zoom. We're gonna have the winners. So Adele, you should be moving over to TylerGuz.com's Live Zoom. It's free. All right. What was the first, no, what was the fastest growing startup to exceed $150 billion in valuation or enterprise value? What was the first company, sorry, the fastest company to obtain a $150 billion, you could say market cap if it's public. I don't wanna give away whether it's public or private, but valuation, $150 billion, not million, fastest. And I'm gonna add something. Non-social media platform. It was, we're gonna exclude social media platforms. What's the fastest kind of startup that wasn't a social media platform that went from zero to one? Because Snapchat is, well, actually you can include social media. The reason I wanna exclude TikTok because TikTok is the fastest company, I think, because it almost achieved. It's a private company, but it's probably worth three to 500 billion if you use Instagram as a comparative, right? So what's the fastest non-social media platform? Business startup, somebody said SpaceX. No, SpaceX has been going forever. You can only win on TylerGuz.com's Live Zoom. You can observe on the other platforms, but move off, it's free to go on my Zoom. I like to talk where I can't be censored. Social media has a lot of censorship, including TikTok, including Instagram, including maybe not Twitter as much anymore, but I'm not that focused on Twitter. Somebody said, Saudi? No, I'm surprised nobody's getting it. Amazon, no. Amazon took a long time to breach, broke, you know, go past 100 billion market gap. 100 billion is an insane number. Windows is not a company. Apple Pieces, somebody put. The Apple Pieces is not worth over 100 billion, okay? Door-to-ash, not even close. Nike took a long time. Nike was like 10 years in the 70s, wasn't making any money. I've got a lot of company that has crushed the game. It's in the last 10 years too, but not social media platform. I excluded that. PayPal is the wrong answer. Louis Vuitton is the wrong answer. TechCrunch is not even worth $10 billion. ByteNance is excluded. That's TikTok. Kylie Cosmetics, it's worth one billion maybe. Uber was, Uber is fast, but I do not think it exceeded, I said 150 billion valuation. At least for a day, it was worth 150 billion. Tesla, no, it was started back in 2001. Took a long time. Netflix, no. Netflix has started in the 90s, man. Zoom, Zoom exceeded 100, but I don't think it exceeded 150 billion. Not one person's got it. Maybe they have, but it's gonna slack as only it was worth about 50 billion. Fenty beauty, no. Come on, those who do not know the past are doomed to repeat the failures. Those who understand the past are destined to repeat the successes. That's my own version of that saying. Those who do not know business past are doomed to repeat the failures. Those who know past business success are destined to repeat the successes. It's not Zoom. It's not only fans, it's not worth over 100 billion. Only fans isn't even worth 20 billion. It gets a big discount because it's kind of a porn type site. You're not gonna get a lot of buyers. Stripe, no. Stripe is not worth. The only company I've seen that took beside social media platforms that exceeded 150 billion. Lehman Brothers, no. Why does it, it's not Avant. SpaceX, no. Alibaba, no. I haven't even seen one person get it yet.   That was purchased for three billion and then shut down. It wasn't a good story. YouTube, no. And YouTube started a long time ago. It was purchased in 2000s, I can't see that. No, not Exxon, because Exxon's a company back from like, it's like Shell, that's back in the Rockefeller days. I think Exxon was part of the breakup back in the 1920, 30, 40s. Okay, I saw the first person get it. Somebody figured it out. All right, here up, this is the first person, I don't know, actually I see someone person right above it. It is Cher, Cher. You forgot to put your, we have the actual Cher on here. Are you the singer? Did you come on my giveaways? We have Cher from Las Vegas, who gave the answer Cher. Can you, real quick before everybody tries to win the money, that's yours, $200. I'm gonna Venmo, do you have Venmo set up so I can do it?  Cause I'm about to go, I'm about to stop the giveaways here, turn off this and go back to the, we're doing it for all of you watching, I'm doing a two day challenge. It's an online Zoom webinar. It's eight hours, four hours per day. And I have multiple speakers teaching you the cutting edge ways to make money in 2023. We had one of my students who started with me as 16, he made his first million in the bank at age 19, Nicholas Pette, he's now, he's from Germany. He's about 24 years old. He makes two, 300,000 net a month. He was just teaching, you missed it. Michael Sartain was teaching two hours ago on how he's making $500,000 a month with a small following on Instagram. 500,000 a month, I've known for a long time. So everybody should be coming over to tyloves.com. So I zoom, more important than the giveaways.  Okay, here's the Venmo. Everybody watch, share, share his real name as Victor Zapata. Okay, that is an interesting name that you, why is your, are you on your mom's zoom? Watch this, I'm on here, on Venmo.  This person, I'm typing in 200, that's $200. What's this for? Give away trivia, boom. I'm pressing pay. I will pick and I will press pay, let's see if it goes. Just to show that I send in the money right now. And who's the last person that won? I owe them 150. There we go, you send a payment. The payment was sent. It shows 200 out of my bank account. You pay Victor, October 9th, 2023 at 315. Victor does not work for me. I've never met that man. The last one was- Okay, let me see the Bitcoin wallet. Well, it hasn't been sent to me. Okay, so, everybody, we're shutting off social media. I'm gonna do a couple more giveaways, but only on zoom, we're gonna shut off my social media so I can focus. Again, we're doing eight hours of content. You already missed three hours of it. It's a free two-day challenge with the most cutting edge ways. I have multiple speakers. I have like six speakers plus myself. It's all day to day. You can join for the rest of the day. It's all day tomorrow, okay? What's four hours tomorrow? 12 to four Eastern time. If you want to listen in, which you should, just go to television.com, sign up to zoom right now and you'll be listening in, okay? Hope not boring speakers. Hell no. I just had two people. I have one kid who became a millionaire at 19. He's been following me since 16. He told me how to make theme pages on Instagram and then monetize theme pages. You ever seen those Instagram pages where there's no face on it? It's just like faceless theme pages where they talk about different subjects. He's the master of that. He shows people how you can make a faceless theme page on Instagram. We have a program together, but he was teaching for free for like an hour of solid content, okay? So you want, don't be missing out. I got multiple speakers today and still more tomorrow. Ned Bragg said awesome presentation so far today. Yeah, for those of you who've been on the Zoom, has there been good stuff or what? By the way, what is the place they can register? What's the registration? It's, well, can you, so I can see it. What's the register link that they can register for the, because tomorrow we have a ton of speakers. Is it title.com slash summit? Let me see. We have a two day challenge. By the way, I'm teaching right now, I'm telling people, I'm showing my team how I'm showing actually everybody was on the Zoom, how you can use Zoom to make money. I don't have to be, I've made millions by using Zoom. Millions, more than that, but I made millions by doing Zoom. And so a lot of you, I asked you like, I was asking today, why haven't you made a Zoom? Even if you only have three friends on it, that's the beginning. I started my email list in 2012 with three people I put on, my three friends, and I started sending book summaries. Okay? Within a year I was making millions. You got to start small, start small, start small, start small. You can be setting up your own Zoom, invite your mom and your three best friends and say, I'm just going to be talking about what I learned on the two day challenge that Ty did with multiple speakers. You can just re-teach this. You see what I'm saying? You just re-teach it. And yes, the answer was Shopify for the $200. Shopify was started roughly 2013. And I remember looking in October of 21, it was at 165 billion market cap. It was more valuable than McDonald's, which is mind-blowing. Now it's come way down, but the question was who was the fastest to achieve it for at least one day? So the answer was Shopify for anybody wondering. Now the fastest company, including social media platforms would be TikTok. TikTok came out of nowhere. They bought musically in like 2016-ish 2017. They rebranded it as TikTok and they spent 18 billion on marketing in one year last year. So they spent a lot of, they invested a lot. And I mean, TikTok's private, so nobody knows, it's probably roughly a 600. I would say low-end, it's a $300 billion company. High-end, it's 600 billion, okay? The fastest was Zoom in COVID. Zoom has not, as far as I know, ever exceeded $150 billion like Shopify did. I remember when Zoom was 100 billion, I couldn't be wrong, but my recollection is that Zoom peaked around 100 bill and dropped precipitously, okay?  The link, wait, that's too long. We're gonna make it, we're switching it. Give me a second, I'll talk for one more second. I'm gonna give you a link and you can come and register for the one we have now. Unpin this and you're gonna give me a new one. What's some quick questions while I'm on, before I turn off the social media and focus just on the private Zoom? What's some quick questions? Let me read some here. Somebody said, damn it, I just joined, I missed out. What are some questions? I'm looking at my, what's the most helpful book you've read recently? I think Shut Up and Listen by Tilman Fertitta is a great practical business book. Shut Up and Listen is one of the guys I look up to as a mentor. He owns the Houston Rockets. He's worth about $7 billion. He has a book called Shut Up and Listen. It's great. It's a great book, it's just real practical. Know your numbers. One of his chapters, things like that. Okay. Okay, more questions. How can I make money like you do? Copy what I do. Do a Zoom conference with five friends on it. Start small and build up. I started with three people on my email list. It eventually grew to millions.  A big oak tree starts with a little acorn. Some people are like, how can I be a big oak tree? We gotta be a little acorn first. And those people are too weak-willed to go through the growth process. Most people are too weak-willed. We live in a world where people have become weak-willed. You've been tricked by the system. You've literally been tricked by the system. You've been tricked by the system. Okay, if you wanna make money like me, you gotta follow the path, you know? Take action immediately. Do stuff. Find actual mentors who you can shadow and replicate what they did. 80% of people making money online just shadow what I did. Now a lot of them have egos and they won't admit it. They have business podcasts. I launched my podcast in 2012. There wasn't really anyone doing business training online at scale when I started. There was Gary Vee, but it was a little more a book author and he was doing like wine. That was his big YouTube. There was Joe Rogan, but it wasn't so much business oriented. I started this thing, half the people, literally giveaways. I was the first person doing giveaways at scale. I was doing video ads. Now everything's video. Everybody realized video ad wins. So you just gotta mimic, you know? That's what 80% of the people that you see on social media making big money are my students or in my programs or just duplicated what I did. I was building funnels. I see people have funnels now. That's my same funnel that I built 10 years ago.  Well, the guy who made the most money online as a social media influencer last year is Logan Paul. He made 70 million. He brought me on his podcast a few years ago and he said, five, guess how I learned social media marketing? I was in your social media court. He admitted it. He made 70 mils. People that won't admit it, but told me privately, all of them almost, almost all, almost all. But you don't always want to hurt people's feelings. It's important for some entrepreneurs to be perceived as people who figured it all out on their own. I'm not like that. People are like, you talk about books too much. I'm like, I'm willing to admit I learned from a book.  But that's okay. That's okay. Emulate, mimic, shadow people. Okay. So the answer, I'm gonna give you a link in a second for social to come. Let me answer a few more questions. I went underground. I took the last two years off from social media. I needed a break. I'm back now. How faceless videos will make money? No sponsor. I didn't say faceless videos, faceless channels. You're gonna need faces in videos. Elite gospel girl. I bought your 67 steps years ago. Awesome. Awesome. Ty, you should start on only fans. Yes, I will show up my booty for money. I don't think I can do my number one way to make money. Okay. All right, more questions. But thank you for the advice. That's amazing advice. I will get my only fans up immediately. All right, let's see a bank balance. My Venmo, I just said $200 on Venmo. Yes, the smartest thing you can do is show all your personal information online to strangers. Remember that, ladies and gentlemen. Would you like my social security number two? You know, I've had people try to take out, always get those credit check, locks. I've had many people, hackers, multiple times in the last five years, somebody's tried to get a mortgage using my name.  Like credit.com or whatever. I pay like 50 bucks a month. Those guys helped me lock down my credit. Don't be giving out your personal information online. I've literally had more than one person apply with my name, you know, it's kind of insane. Okay, so I'm gonna say, Ty, you were wrong about Napoleon being the first trillionaire in the last 500 years. It was Akbar the Great.  They don't teach us the whole world.  So I only know American history. I mean, it's hard for me to know Akbar and, you know, all the African, those people, there's not even that much info on. Ty, the Fresh a Fit podcast was awesome. Good. Okay, so go to register, tylovis.com slash s, the letter s, tylovis.com slash the letter s, tylovis.com slash the letter s, like family. Okay, we're turning these off Rick and we're only on my private Zoom, we're continuing. We've got new speakers coming up very shortly.


You could get hit by a bus. Then where your projects are going to be. I know you don't care, but other people don't care. So two things first. It is okay if you fall asleep. It's the end of the day. It's hot. You've been busy listening to lots of things. I know when I'm at a conference, I'm just behind a stand all day. And if I sit down for like five minutes, I doze off. So I'm not going to be offended. I totally get it. Secondly, it's okay if you can't quite understand me. I grew up in Los Angeles. I then moved to New Orleans. Then I moved to Nottingham. And now I'm here at Belfast. I know my English is not your English. It's mine. Come get me afterwards. We'll try to make it make sense. So to start out, I have two stories. These are things that happen to me. Like we said, I did my first website in 1995. I've been working in the business since about 2000. A lot of terrible companies. The first one was I was tempting for a job, or a CSS design job. The designer had broken his collarbone in an accident and could not type. And they desperately needed to get this website done urgently. They needed somebody to come in and be able to do it. This was in 2004. So my CSS knowledge was not so hot. But I wasn't given something like that. I was given beautifully laid out code. He had comments in explaining what each single bit did. He had everything organized, filed perfectly. And I learned more about CSS in those two weeks than I had the years before.  I don't know who that guy is. I love him. My second one. It was a developer. This was when I was working for a tiny e-commerce shop. And I was in charge of all the front-end stuff. And we outsourced all the back-end, the development, the hosting. And we had a problem with our website. It was down. We were losing tens of pounds. Tens of pounds, my God. And it was completely broken. And we kept them trying to call the owner. And we kept them trying to get the developer involved. We kept them going, what's happening? What's happening? What's happening? The site's down. And it turned out that the one guy in the company who knew everything, who was responsible for running the site, who had all the skills, was bit by a dog. And bit by a dog on his hands to the point of being these digits, and he could not type for weeks. To get our site back up, he had to go in, stand there, and tell them how to fix the site while basically going like this. Bad documentation meant that my site didn't go back up. And I got yelled at for the whole tens of pounds that we lost. So documentation is incredibly important. It's incredibly important to you. You are also important to you. This is why you should document stuff. It gives you a reminder of what you've done. How do I do this? What magic was this? You're never going to have to go, was I smoking something? That's fine. What have I just done? And it also tells you what things connect to. That way you don't look at a piece of code you did five years ago and go, I have no memory of what I've just done here. Don't get magic. What if I change something? I have broken everything. Oh, God. So it gives you a reminder of exactly what you've done. It gives you a process. That's why you know that when you make A, it will affect B, and then that will produce C, because you've written all down exactly what it does. And that means that if it does go wrong, you could go, I wrote down where I went wrong the last time. I'm not going to do that again. Next time it's going to go like this, because you remember how it all works. And above all else, it gives you proof. You don't know how many people I know who have to, are suddenly told, write up what you've done for the week, and have absolutely no memory. Just go, I've made something. But look, it shows you. Look at all the work you've done.  I mean, if we look back at my website in 1995, damn. And basically, it means that if you go to your job, your performance review, or you go to a new job, you could go, look at everything I've done. Give me all the money. They might not give it to you, but you've got evidence. And it's very important to everybody you work with. I'm not just talking about your boss. I'm talking about your coworkers. I'm talking about your employees. I'm talking about people you don't even know exist yet, but will be touching your code. They're also important to them. They have their own lives. They need you to be better, to document. It gives them the support that they need. What works where? How does everything connect? And above all else, they don't have to bother you anymore. I know me personally, I hate bothering people. I know you don't believe that, but it's true. I hate to ask people, what have you done here? How is this broken? How can I fix it? Because I don't want them to think that I can't fix it for them. I don't want to have to ask them how things have happened. I just want to be able to do it. And with good documentation, I can just do it. I don't have to bother people. Especially if you're on holiday. Finally, you finally have two weeks in a beautiful place. Do you really want to get that phone call of somebody who is apparently just learning how to change one CSS file? You don't. Documentation. And it gives them the understanding. You want everybody to be on the same level. You want people to understand exactly what you're doing. And then, that way, you can all work together. You get how you... They get how you're working. They understand. They can then build upon that to make even more neat things. And everybody's on the same level or improving together. Management, it gives them evidence. They know what you're doing. They know how hard you have worked. My God, you have worked so hard. Why don't you show it to them? And then, they throw all the money at you. And if they don't, then another company will throw all the money at you. You know, a lot of people go, oh, God, no, this is too hard. I can't cope. I don't ever want to do documentation. No, it actually is really easy. You don't need to be writing epic manuals. No, I've done that. You know what? Nobody reads them. It's horrible. You document why you work. You don't have to comment out every single line. You don't have to provide a giant manual. Just quit, little, explain what's going on. This particular bit of code creates a box that's to the left, and it's blue. And if you put it in here, it turns green. That's it. And if you want to, you can document after you're done. You can produce the bigger picture, overarching, giant detail manual.  Because you would understand how it's been working. And then also briefing someone else. You know the rubber duck theory, where you tell your bugs rubber ducks in order to understand what you've done, because it's the second person you're talking to. Talk to a real person. You tell them what's going on. You figure out together how things work, and maybe you'll pick up new things. Maybe they'll pick up new things. Maybe you'll guys will come together and then create the next multi-million-pound super project, because you just talked about that tiny bit of code. It could happen. So, why is documentation awesome again? You know what it is. It is. It shows you what you've been doing. It shows your coworkers. It shows your boss. What if open source projects help? It shows the entire world. But you want. You want people to know that you are making fantastic stuff. And, why not tell them? Or even better, why not just be left alone by not having to have people question you about things, because it's all right there. You can either be showing off, or you can be left alone. You can do both with documentation. So, if you have any questions, you can. I knew it was under 10 minutes. Hot damn! If you don't, I'm on Twitter. I don't recommend following me, because it's literally pictures of the cat that hangs out while you go up. Unless that's what you're into. Go team. Or you can find me tomorrow. I'll be at my stand. You can talk to me anytime. But if you have questions, now is the chance. Thank you. The next time I come to that decision tree is to spend the next two-hour documenting that. I'm going to have to go back and watch the video of this doc, because that was fantastic. I was so motivated to document something after that. It's the phone call Thursday afternoon while you're on the beach. Or while you're making Easter dinner. Because that has happened to me. And I said, I have documented it.  See, that is the problem. You can document it. But at least you've done it. And you could go, so you've read my emails, yes? Bye. Slime. Okay, here's a bold first question. What exactly is documentation? It could be anything that explains what you've done. Because I would have thought it could be everything from comments on a line of code to a git commit message to the full life story with a thousand more articles about why you've done that one thing. It can. I always like, because basically most of the time I come into a project it's after somebody's left and there's nothing. And anything that remotely resembles documentation is therefore a God's end. So, yeah, it's all dependent upon what you need to do during the process that you're making something. A lot of people go, I don't have time to think about documenting it. You have five seconds to write a comment. It'll help you in the end anyway. It'll help you anyway. Or you might have, you might get lucky and you might have a proper sprint system where you have the meeting afterwards where you go over where everything is done and those minutes, if you want to take minutes, the minute, you can take minutes and that can be your documentation on it. So, basically, there's a lot of opportunities that you just need to go, you know, since we're talking about this, let's just write it down. I can empathize as well with when I'm writing the documentation before I flesh it out. So, proper English, I write just bullet point notes with very sure hand and that's enough for some people. But in terms of writing documentation, are there any things you would recommend not to do, things to avoid, pitfalls, problems? Giant paragraphs. You know how you start out with a bullet point and that's fine? Oftentimes, that's all you need. You might want to maybe expand it out to a sentence. I actually just wrote a guide for our resellers on data protection. Keeping it very vague, because I know I'm not a lawyer. And I started out, I just basically bullet pointed everything I knew I needed to put in there and then most of the time, it was just turning it into a proper sentence and it was done. If you know that you want to talk people through a particular process, order this. One, two, three, four. Click, click, click, go. Immensely save so much people, so much time. They go, wait, where do I go? Don't forget file names. Just say, this is the book that tells you everything. What about publishing documentation? Where do you put it? Usually most of my documentation is completely internal, so it just sits on our internal compliance section. With very clearly said, this is this thing. But other times, if it's say a manual for customers, it goes up in all the appropriate channels that the people might see it. If it's a project that we've worked on and we're really proud of, we'll put a blog list about it. Going, hey, check this out. This is all the stuff it does. Here's where we might have had some snacks, but we totally got it sorted because we're cool and this is how we're cool. And do you then treat that like any other content artifact where you then come back to it six months later ooh, is that up today? Or is that gone stale?  The content team with me. Sometimes I do go back to it. Sometimes I go, well, that's how it was at that time and if I were to go back and fix it that I'm going to put something new up because things have changed, which is the big thing to say. Well, back then, that's how it worked. We've had to make some changes. Here are all the changes. Now that works. Anybody else questions? I was asked there with that. So you said all of your stuff is internal documentation. I presume that processes the way your team works. Yes. So therefore I presume that would change over time. How does that get reviewed? It gets revisited when it changes. So my best example is for some reason, WordPress and our blog and our servers don't like to talk to each other particularly much sometimes. So you have to change your host files and your staging servers. You can upload the images right so that then you can sync them in. Eventually we're going to fix this and then I'm going to go back and I'm going to go again. So all of that, that's gone. You don't have to deal with that now. We can make it easy. Right now it's a disaster. So a lot of it is going, well, this is currently a disaster but here are our fixes around it. Then when we get it fixed, here is how it actually works. We're doing this right. Because I hear so many people saying our documentation is terrible but I'd like some of this done. You know what, we're pretty down good at this. I mean it's not quite full-time but I really like Mailchimp's style guide. I'm used to Mailchimp. Because they have it all out there and they say this is exactly what it is and it doesn't get as bogged down as style guides get. The logo must be 50 pixels that way. A lot of good, some newspapers have their tone of voice articles as well. Those are all fantastic. I mean the Metro doesn't have it out for me. And then just basically look at non-software companies because they might have something up there and it tends to be, especially the bigger companies, they tend to have an entire company involved around it. I like to think some of my documentation is good. I'm sure everybody can tear it apart so it's usually just me going, what have I done? Okay, that was absolutely great. I can't think of a way to finish today so thank you very much.


Hello boys and girls, welcome back to another Subaru video. Now this time I decided to get a vacuum-actuated exhaust valve cutout. By the way, is the camera still flickering? No more fluorescent lights. It's all LED now. Still not done. Here are the old lamps. Still in the process of installing some more. This one still needs to be connected. So this is a dark area right now. There's gonna be more. I got three more I need to mount. Two more here on the ceiling and check this out. BAM! And one more there. Anyways, I did install an exhaust cutout in the pipe a while back or when the car was apart. I had the exhaust out anyways. So this is what I'm talking about. We are a little bit back from the middle of the car. So as you can see, this is the cutout. I simply, this is three inches, I simply cut my exhaust and I installed the cutout in between here with clamps. No welding was involved and I was planning to just, you know, whenever I'm in the track raise the car up a bit, remove these three nuts and bolts. Install this piece here just to point the exhausts out. So it would look something like this. Okay, but then I figured, okay, that's gonna be quite some work. What if I have something else to do at the track or whatever in between sessions?  So I decided to get a vacuum actuated valve, which is this guy here, also three inches. And the way this works, you simply connect vacuum to here. The other end you can connect to your intake manifold, whatever there is vacuum, whatever you have an opening in your intake manifold. And then it would open as soon as you give a throttle. I think it works from between minus five and minus two or something like that. So, you know, not much is needed. This actually works. It closes up pretty tight, as you can probably tell. But I don't want it to open when the turbo engages or something like that. I want it to have it on a button. Okay, obviously this is gonna be loud. So I don't want it to turn on when I'm driving in the city or whatever. So I need to connect this part to a switch, which is going to be run or turned on by vacuum. So the switch is going to be fed vacuum all the time. And whenever I'm ready, I just flip it on and the switch will provide vacuum to this valve. So the plan is to get it, can't put it right against it. It's going to be too low. It's going to be too close to the floor. So my plan is to either get it somewhere here in this area. So the valve is kind of tucked away up and away like that, something like that. So we have to make a turn or get a straight pipe from the cut out to here and end up somewhere over here. But that's gonna be, that might be in the way unless I turn it like that. But then I don't like this hose being too close to the right side there, whatever that is there, the cover. So the plan is to end up somewhere here and obviously the tip, well actually maybe as close to the side floor here with the valve and the tip right here. So it's as far as possible from the gas tank over here. So something like this, as high as possible and as far as possible from the fuel tank. So first what I need to do is get a flange, a pipe with an angle about 45 degrees or so. Make a connection, obviously I'm going to weld it. If it's not going to be like this, it's going to be hard to find a piece like this with the angle that I need. So I'm going to weld it, weld the pipe to the flange. It's going to come out somewhere here. Then I'm going to have to, I got no other choice. That pipe coming out, it's going to get welded to the valve. Hopefully it will not hit. The butterfly will not hit the inside of the pipe. I'm going to have to make sure of that. This may be actually a bit smaller than 3 inches, I'm not sure. So the way this needs to be done is I got two options. I can either weld two flanges to the valve on both sides and then get another flange and weld the new pipe to that flange on both sides. Or I can just weld the pipes directly to the valve and call it a day. But I have to make sure if I'm going to weld the pipe, I'm going to have to make sure the butterfly does not hit the inside of the pipe. Because as you can see, as this butterfly opens, it sticks out a bit. Well, now that I look at it, it should be fine. Okay, so the chances of this butterfly hitting the pipe inside are slim. So I need to go shopping for some pipes. All right, this is what we got. So this is the plate that I took off with a gasket. First, this fancy pipe is going to get welded to the flange like so. This is the flange out of this, by the way. So that's going to be removable. The whole thing is going to be removable.  Once this is cut, the valve is going to get welded to the pipe right about like this. And then this piece is going to get welded on the other side of the valve. Now the fuel tank is about right here. So that's obviously going to point away from the fuel tank. All right, I was going to weld flanges on both sides of the valve. But that's probably too excessive. So the flange will end up here and the whole thing is going to be removable. That's the plan. In case something happens, whatever, then I can just put this plate back on on the original cutout spots. Okay, after some professional measuring and drawing, I came up with this. I got lines here and on the pipe. That's going to get welded here. Let's do some cleaning, cutting and welding. And that's it for this one. I had to break this down into three different parts. Couldn't bore you for too long. So the cutout is going to get paint, high temperature paint in the next one. And then I'm going to hear it, hear the car run actually. Open exhaust and closed cutout and then muffler. And then I'm going to explain shortly why I did a street tune and not a dyno tune. So please subscribe if you haven't done so. And I'll see you soon.
