Hello everybody and welcome to the first ever episode. I'm doing a Yes, this is a game where we take control out of beavers Yeah, you hear me, right? We like I've been carrots. He's loving his life Loving it So if you remember I played I played a game where it was sort of medieval and you had to fight dragons and stuff It was very low poly and that was sort of the charm to it This one is very similar. You start off is just like we had just this little thing district one I've done the tutorial so I kind of know what I'm doing and we're about to undergo a giant renovation project here to give Our beavers a lovely better home. Look at him go. He's like, oh, I cannot wait. It's going to be brilliant And I've just this is it right here look at it. It's massive So we need to get more water mills in order to write. I got you. What are you doing? Cat's in age two.  Oh God. Don't look into the water Don't look under water by your cat. There's there's nothing there, but death Right, okay So if you're familiar with any sort of town building simulators and like a stardew valley as well a bit farming there, too It is glorious So we actually don't have enough adult beavers to work the amount of stuff We've got going on all of these things to click on the bottom and then it's crazy It's crazy the amount of things we've got going. So this is what I'm working towards I want to make my beavers happy because if you make them happy they I don't know I think they do better you unlock some sort of perk To unlock a reach average well-being of 15 while playing folk tales progress five out of 15 So in order to get certain things they need all of this which is kind of crazy We've only got five one two three four. Oh wet fur I don't know how to do that a focus on the main priority at hand and that is getting houses demolished buildings and reasels Just knew we don't want to do that. Also these seasons change So you get droughts in this and when you get droughts the water dries up the water dries up There's no more power. No more power. Well, it can be bad. So We need more beavers. That's what we need. You know what we don't need Berries we've got plenty of berries. Stop it with the berries. Look at them all look at them all So actually what a lot of carrots going on I suppose Okay, so we got a water pump which gives us one water every half an hour or we could get three water Discharges water But that doesn't sound good to me. I placed my water mill here, right and it's getting me Power output 80 it'll tell you I mean even just these two are different 71 80. This is a better current So I'm assuming if we put that in the water. We'll find out. What's the best place to put our wheel? I mean, I'll put it here for a for a hot second just to say let's put its priority to utmost priority, although it's night. Okay, hold on.  Why not?  Yeah, there we go. What a current nothing So Okay, okay, that's interesting. So there's no point It is giving no current. So we don't want to put a water wheel there right gotcha. Okay, so we can just get rid of that We get our resources back. So that's fine This will this will still work it'll still give us water and that's what we kind of want Oh Right, you can't make it over the farmland interesting, but you can put it up there So if you wanted to you could put stairs up to another storage here Ah, I love that is there is really struggling It takes them an hour and a half or an hour and a bit to make one plank and each one needs four planks So Yeah, definitely got this this is one hell of a project. I've got going here. Oh, also we got our inventors in here And that's how you get points in order to unlock these sorts of things. You can get some crazy bridges and stuff Um, what do I need to do? I always kind of want to do this. So So I got houses. We've got that this huge house So what you could do is we could rotate this that way And have that there at the end try to think of a way that would make this Seem better and put one there and put one there boom Let's put the priority On to this piece and this piece because that way at least they can get into those Yeah, look at that 193 oh, I didn't realize we got a drought coming. Oh god. It's coming soon, right Oh, we got a guy who's working on trees with broken teeth Bless him. Well, I haven't had a single one dire. I'll be sad when one does because eventually it will drought start Okay, here here it comes So get ready for power to disappear. What I will do actually hold on. I'll pause that yeah powers stopped zero Ah brilliant. Okay. Now what I wanted to do was this A land wheel kind of wanted to go that way in fact actually. Oh the only thing that's here is one of those Oh, who cares about that then? Beautiful. Okay, and then we'll play we'll put this on high priority These things because at least we can still Get some power. They are working on it. We do have 116 wood. So that's great We just need to wait for night to pass Ones night passes. Were you good? There we go Bruh Inventors invent and you're paused but then once this wheels up and running Which it is and then the power is connected. Look at them go beavering away Yes And can you not collect that stuff full power hybrid? Yeah, did you help? He's went from his other job to now doing this Once a beaver of fine craft now. He walks for a living So that's so cool we're in the drought and you know you have to you have to do with what you got and now We are still when we're doing this. We're good. We're turning logs in the planks, which is brilliant Well, nothing else can happen a lot of guys are probably unemployed I mean we got the berry station here, and then they're gonna go off and collect all these berries I'm fine with those berries, but I want this bit. This bit needs to be you know the hub of activity This is where we're gonna cut everything. There we go Nobody collected it until I made it high priority Although I don't think anyone could get to this. It's only one log though. So it's not really too much of a priority. Oh Look at that. You've almost oh wait. I can get rid of this now That home you've lived in for ages. It's gonna have to go by Just when they're sleeping Destroy the house. Oh, you know what is we couldn't make potatoes in the middle. I've never made potatoes. Oh Yeah, this is a warehouse. I think it just has lots of carrots Although no goods are stocked in there at the moment as you could see we have no crops We are literally yeah look them all taking the carrots and stuff little sign of telling you what they are Yes, the drought is over. No. Oh, there it is Now we have so much power you can stop spinning that now There's no need off you get and get on that make your gears Although there's different things we can do when it comes to power like we could do a windmill 1,400 for a large windmill though. It does give 400 Jesus How about we just do this one will unlock the small windmill and we can probably put on top of houses We have oh my god. We have no carrots We've got no bloops. Oh, okay. Okay. Everyone's I was not happy. I realize now.  No, no one I made that high priority. I know you guys are starving. We're waiting for the harvest boom There you go. There's actually underground storage. You can make as well We should be grounds only must only is unique to this faction So I'm assuming it would just be like one entrance just a tunnel down. Did they die? I hope they don't die if they run out of food because everybody's starving. Did you make it? Oh hell? Yeah, you did. Okay. We need to design what what it's for We'll have this one is planks like they're taking care of their carrots. How close are they? Ah Okay, then 99 percent dot. Yes. Look they're popping Yes, carrots are back on the menu boys and then they're instantly eating them I Think we'd start food weeks. Look soon. We'll have potatoes. It'll be all right. So delete that How long the potatoes take six days and you get one potato that's that's fairly long time But do we have a place specifically for right paradise potatoes like me the potato house Oh, that's perfect. Put the put the put the put the fire right next to all the houses We could put on top actually. Oh heck. Yeah, get that grill up there. Yes Beautiful it's like a chimney. What's we got? We've got a grist mill.  Okay, so that's changing from wheat into flour. I assume a bakery Okay, well we don't have any flour All right guys, we've just got the timer three days to the next route, but I'm I'm looking hopeful You know, we've got this irrigation tower now, which is really gonna help Hopefully keep all the crops still growing while there's drought because every time a drought happens Soul dries up crops dry up and it doesn't all look at the little baby Bruno could yes a fine name Also, why is this berry bush still here make it a top priority lads away looks unsightly There's also different districts. I don't know how to make different districts though Which is the interesting thing I'm looking forward to it also if we look at the map. There's these structures So I think this is supposed to have taken place in a like a you know after humanity his long Disappeared beavers have now become the more. I don't know special species Smartest so these are like old infrastructures like a metal and you can harvest those for something I'm not too sure what hey your beavers are happier than ever you've reached a new well being higher score Suede is that because a grilled potato? It's because I grilled potatoes Broke a teeth though. Don't don't really know how to kind of stop that from happening. Yeah, look at him Smoking them potatoes. Oh Beaver is injured. No, how do we make a hospital healer? There we go makes medicine and distributes it to medical beds teeth grinder basic broken teeth That's what we need they need to have these things. I'm assuming visitors want oh there we go Okay, you know what I'll spend the points on it medical bed keep them in the shade there we go We don't want you don't want to be able to look into the medical beds. That's not good. We're not even halfway He's using all the water to fill up the rent to keep the crops from growing no no no not needed pause it pause it pause it The water that's now stocked up in here. No everyone else is out of water. We're not even halfway through the drought Okay, good. They just took it out. Okay. That's good. That's good. We've got plenty of carrots to do us That's that's more than fine, but they've shifted all the water around now so they can drink it Oh good. I was getting a little bit worried then right. Okay, so well one day away. We have 19 water But my brain yaks are going out and look at them Hey, so yeah, so Dalla Nail and key don't sound like beaver names No, he's given power to that one I don't even know if this one gets power like we give it power as long as we're still making some planks That's the important thing. There we go Beautiful working at a hundred percent capacity now. What did I get? Oh, I give the oh, I give the cap by the rooftop terrace Oh That's brilliant They're so cute. Look at that. They're up here as well. Oh my god. I love this game But this is so cool. Although we are desperately out of water. All right drought ended Play top priority get the water in there. All right. There we go. Oh, I made the adjustments I've got rid of all of the small little water things because we didn't really need those and Instead I put a big one here So this one can be used for the crops as well as refilling the air The almighty reservoir thing and then we've got the big one over here Which when everyone wakes up to they just go and get their daily drink of water. That's it They only get one sip per day Okay, guys don't know where I last left off we've got a good harvest of this crop, but I don't know Things for some reason went a bit crazy for a while. I'm not exactly too sure why We finally have this up and running and they're slowly taking water to it, but I Realize I think the problem is just taking things and carrying it I don't know what they're holding off. I think well, this is water 14 of 14 kilograms of seven water and that is Half of what this thing can actually hold and when they're away It's not getting anything like it's not pumping any more So what we need is people to transport this to a different area and that's what we need a holding post for so we're gonna make that top priority and I'm hoping I am really hoping by the time we get the next route We are just fully supplied on carrots and everything so I have 45 wheat in there actually loads of wheat so much wheat in fact I think I need to get rid of this wheat Not that one. So who did one need to get rid of that wheat and then make another Storage for the wheat. We've stopped production on brains as well. That's that's not happening. I love this bit This bit's perfect. I'm kind of I'm getting there with this. This is good, too We've got lots of teaties. I don't know how many potatoes we've got only one. I guess people are eating the potatoes So we probably play that unless oh and I we'll be making grilled potatoes That's why everyone's got a happiness of eight. Oh my god. This is seven days of drought. Oh No, hold on. Hold on. I need to think about this Seven days of drought. I do not have enough water Okay, we are back guys after our last left off. I kind of just decided to play this by myself for a good few hours I restarted because there was no there was no end in sight. It was gonna go wrong But here we are this is the last hour before it becomes drought and We have 969 water we have like I've done so much like look at this. This is glorious I've figured out so much as well. We got baths. We got campfires We got shrines there. We got this little pool pit thing as well We have this we have 60s heaven of these guys There's a lot of minus ones because everyone's hungry, but but I realized why everyone was hungry And that is because these farmhouses is how they cut crops I just thought they ran around and just picked them randomly. No, no, no You need to have them assigned to farmhouses So I played after during the drought and everyone died. So this is Right at the moment where things can go wrong and I think I know what I did. So we I've I made this little place. I had loads of fun Building this how all these houses here. This looks awesome. I loved it. I love it so cool I love this sort of you know everything just on top of each other little higgledy biggly I've also got all this wheat and we've got wheat flour there and we're about to build a Bakery on top now. You can actually see we're also gonna have some power from the windmill We have some loads of amazing power here. This is spud factory. However I've just made this this thing here. It has no water in and It's gonna be make or break guys. It's really gonna be make or break I'm think I'm gonna have to put all these on high priority if they don't have anyone in them But they actually do which is great. We have one here as well. It's oh it has everything Okay, so we need to sign this to water as well And I just wish there was a way for me to say to my my beaver's like no we need water screw everything else We need water because I thought you know it'd be fine We got like almost a thousand of water. No, no, no because I had this Irrigation tower of this irrigation tower, but what I realized is actually most important is this Irrigation tower because this is gonna supply the wheat with the water it needs and for every I think what does it say? Well, we'll find out what recipe here. We go bread. So I think the bread recipe you make five bread for every one Flour and we have 48 flowers for 48 basically 50 times by 5 You've got 250 or something you've got lots you got to yeah Every 250 bread and that's why everyone's suffering with they're all hungry their productions a little bit low at the moment But I don't know we're gonna jump in and just see how it goes man. I'm nervous. I am really really nervous Okay, this is it the last day. We made it the last day of the drought and we have Literally no water. That's it and we had 60 odd remember. We're down to 38 People are now starving and dehydrated. I don't know man. I think I think I've got to reconsider How I do this because how I mean I need to Kitchens and it two of these kitchens to work hard enough and fast enough to supply my workers with food So that they they have production and then they don't start dying and they can keep on repopulating because at the moment They're just so weak that they are they're not reproducing because they're unhappy because they're hungry if they weren't hungry Then they would be fine and the population would be going up. So oh god There's like a failed attempt attempt number two technically of trying to get this to work basically it can work I know it can work. It's looking promising three giant vats of that This thing that just needs to go up and running. I think we can do this It's gonna be close though. It's gonna be close Okay, there we go. Oh I've got two of the mill things. I've got two bakeries and we still have 68 Beavers left we have four point two days We have four hundred water don't think but we know the water is gonna run out pretty quick I think the last day we have no water But as long as we can get the next three days with everyone You know satiate with their hunger. We can get these mills pumping out flower. I mean I've only got a hundred and eleven wheat But double the production Should really be enough. I think in order to turn out, you know ten bread every hour So you know the whole day we should have a lot of bread We should have a lot of bread. Okay, so we've done better this time We've made it to the final day and we've still got lots of water But we've got 32 we've lost like 40 beef I'm assuming due to like well I mean they're not making babies because they ain't happy but at the same time at least we're getting food We just need to make it. This is the final day Got to 31 beavers way better than last time. What is gonna come back? As soon as that water comes back the crops can come back and we'll just see how it goes I think it's gonna be close. It's gonna be really close Okay, okay, we made it 26 beavers and we're doing good. I think Run off to die right I've decided I pulled out everybody from everything and We are now Yeah, I'm gonna pause that I'm gonna pause this we're gonna pause like wheat production bread production We're gonna bring everybody into the fold into here to focus on the carrots Focus on what little water production we have going here. Nope. We've lost this one. Okay. Okay. I don't know what to do Let's wait a minute the carrots are gonna take four days to grow ah Bowls Okay, I've made it to the last day. We have 28 which Seems like what I had last time though It just seems like two bakeries are too slow and then if I keep all the carrots going at the same time Well, I'll run out water and then there's no way to to get the water again. So We're on the final day 28. I think that was exactly what we were on last time. I Just thought there was a shot. I thought okay.  I think the amount of bread is Is keeping everyone kind of happy? Do we have any babies? Oh Wait, I should be doing it. We have a baby because yeah with all the beavers dying There was less need for that much That many bread. It's actually worked out. Yes Yes Okay, and now we need the water pumps will turn on just these ones over here I think we're with a shot guys. I honestly do Get these guys going pump and water and now these are just gonna grow because they're fertilized by the Hydrated by just the general water then everyone everyone else's happiness is gonna get better because they could take showers now Oh, did a berry die? No, it dried out. There's too much too much. You just couldn't take it Oh, yeah, some of them have gone these droughts are getting nodes, dude Okay, okay three babies. Yes, some of them are happy. We're gonna do it Okay, up the carrots are on the go. That is fantastic Yep. Yep. Yep. That's good. That's good We don't need power. That's fine for the bread The wheat is there the wheat is going. We're on 25 still It's mainly the water. That's what we need is just keep on getting that water up keep the water coming Oh my god, okay, maybe a few hungry, but but we've got a good amount of stuff going now. Oh Thank God Okay guys, I'm gonna wrap it over here. This video has been like two days of recording my god, but Here we are I've just been alerted by the next drought We have got a plethora of food I have enough leeway to pretty much decide how I'm gonna tackle this next one I I still have a fraction of the beavers I had before I've got 12 kids up and coming look at 14 for happiness That's crazy So it's looking good. It's looking good as long as even in the drought. I keep my guys fed and happy We've got the wheat which is just about ready To keep the bread going for over the drought and then Hopefully we can get back up to the population limit. I was at before and we can just like expand and Maybe go up here. Maybe go around here Try to work out how to utilize of this bit the best because that will always have water And if we can build out planks over towards it Maybe just maybe we're in with the shot of having a sustainable amount of water During a drought, but I really guys if you join the video leave a like until next time. I'll see you guys later. Oh, bye. Bye


Hey everybody, welcome to Tudor Terrific. This is the final video, Lesson 5, in my second unit in my physics course on one-dimensional motion. In this final video for this chapter, we're going to look at falling objects. So we're going to bring acceleration due to gravity specifically into our discussion of one-dimensional kinematics. We're still going to be looking at doing problems with the big three. So let's get started. All right, Galileo Galilei, right in the height of the Renaissance and the early Brogue period. He was an amazing scientist. We give him credit to the telescope and many other things in physics. And one in particular pertains to us today. Galileo's famous experiment involved dropping two different sized objects with different masses off the leading tower of Pisa in Pisa, Italy. Now, most people thought that the larger object with more mass would hit the ground first. Galileo theorized that that was not true, that both objects regardless of mass would hit the ground at the same time. What do you guys think happened? Well, to test this theory, we have to ignore air resistance. Objects with a larger surface area, when they contact a larger area of air, a cross-sectional area of air, will retrieve more drag, more air resistance. So what was done in the Apollo landings was, I think this was the final Apollo mission. They took a video, the astronauts of a famous experiment by Galileo, this famous experiment, but done with a hammer and a feather. On the surface of the moon. Now, the surface of the moon is a little bit different than the surface of the earth because the air resistance in the atmosphere is almost negligent on the moon. And so both these objects would fall like in a vacuum. Some physics teachers like to do this experiment with an actual vacuum and you can see quite an astounding result. So on earth, in our atmosphere, that hammer he's got in one hand would fall a lot faster than a feather. He got in the other hand because the feather would react differently to the air resistance. It would fall much slower, it would fall in a wave-like fashion. But watch what happens when he lets both of them go on the surface of the moon. They both hit the surface of the moon from a height of about four feet at the exact same time. Now that's what would happen to objects on the surface of the earth in the absence of air resistance. And Galileo was able to actually show that things with, I bet the ball with smaller surface area actually felt just a tad bit faster than the larger ball. And this was quite an astounding result. And it showed the world that all objects fall with the same acceleration. So, and that's acceleration due to gravity. Now I'm not going to talk too much about gravity except for this acceleration. Okay, let's say we have a little pepper here, held by one of my former students. And we have a vector. I'm going to name that an acceleration vector, so that's why it's yellow. And I'm going to call it G. That's the arrow I give. And the name for the arrow I give to acceleration due to gravity. That pepper, if she lets it go, will fall to the earth, to this lake with that acceleration. We have a giant rock. Let's say we let it go at the exact same time. In the absence of air resistance, it'll also fall with that same acceleration vector, G, okay? All objects fall at the same rate of acceleration if we ignore air resistance. This is something Galileo theorized and he is correct. Now, it depends actually on many other factors we're going to look at in later chapters. But near the earth's surface, we can approximate the value of G as a constant. That constant is this right here, 9.8 meters per second squared. 9.80 meters per second squared. That's its approximation, okay? So if you're near the earth's surface, you use that value for the acceleration due to gravity. Or in other words, G, that's what it's commonly called, okay? It will always point directly toward the center of the earth. Now, if you're not drawing the entire earth, just point it straight down, okay? Now, the most important part is that that air is the same size. That G vector is the same, 9.8 meters per second squared. If we ignore air resistance for any size object, an object with any mass. That's the truth in physics. So we're going to use this in relation to the big three. It'll be our acceleration vector for our problems today. Okay, so we have a problem falling from a tower. Suppose that a ball, like in Galileo's experiment, was dropped from a tower 70 meters high. How far will the ball have fallen after a time of one second, two seconds, and three seconds? If it's falling, we assume with gravity's acceleration. Okay, like normal, we will look at our given and wanted tables. But, but, we must first do something we have not done yet. We must decide a positive and negative direction for our problem, okay? Because some quantities, when it comes to free fall and everything you're going to do after this, can be negative depending on our definition, okay? Because we're dropping something from a height 70 meters up, and it's falling the entire time, I'm going to create a positive direction that makes most of my variables positive. Because I'd rather work with positive values than negative values. It's just easier. So I'm going to make positive downward, and that's why I draw this arrow like this, okay? I draw it downward with a plus sign after the tip, so I mean that downward is positive. Okay, now let's look back at what we're given. We're given an initial velocity, that's what it means. When dropped, it means the initial velocity is zero. We're given the initial position we could say is 70 meters. And the final position is not clear, but we get a bunch of different times. And we know, since it's being dropped near the surface of the earth, that the acceleration is 9.8 meters per second squared. So if I treat positive downward, I'm going to have to change some of these initial values, okay, to make the problem easier. But what I want is how far the ball will have fallen after these times. So that would be the final position, okay, with t at these different values, okay? That's why I have them here. But let's change some things to make it easier. We can set a reference point wherever we want in these problems. So I'm going to choose to set the reference point at the top of the tower. Why would you do that? Why would you say that's zero? Well, you've got to think differently than measuring the height of a tower. You've got to think more mathematically. You can set the reference point where you want. If positive is downward, then the position will grow as the object falls, okay? So it starts up here at zero, and it goes down, down, down. It hits the ground. It'll be at positive 70 meters in this situation. It's perfectly fine to do. Also, I'm going to set my acceleration to positive 9.8 meters per second, because that acceleration vector in this situation points down like my positive direction is. So the acceleration, since it points in that same direction, is now positive. Okay. In order to get the final position, given all of these things, the initial velocity, the initial position, the acceleration, and the time, you can see that the second of our big three kinematic equations is the one to use, okay? The variable we want is already isolated, and all of these on the right side we know and can plug in, okay? Right off the bat, we can make the situation simpler because our initial velocity is zero, so the middle term is zero, and x naught is zero. So we could put a zero there as well. It's a very simple one-half a t squared. And one other thing that we like to do, and I'm doing right now, is I'm switching all my x's into y's. The reason I do that is because we are thinking vertically, and since we worked so much in math in the Cartesian coordinate plane, you might want to think in terms of y for vertical free fall or falling object situations. So that's why I've made that change, okay? So the middle term is zero, and the first term is zero, so all we have is that the final position is equal to one-half a t squared. Don't mind the ones. Those ones aren't necessary, except they relate back to t one here. So we're going to plug in that first time one second in for t, and we will get one-half times 9.8 times one squared, which gives us 4.9 meters. That's how far it falls in one second from its 70 meter height. Now, the second position will be after two seconds. So let's see if it falls another 4.9 meters or it falls more than that. It's accelerating, remember. It's not falling at a constant velocity. That's exactly what happens when you plug in two. You get one-half times 9.8 times two squared, which is four. So this is four times what the previous answer was, 19.6 meters. It's falling at a faster and faster rate as time continues. Let's see if that pattern continues. Let's plug in three seconds, okay? So one-half times 9.8 times three squared, which is nine. So this would be nine times the original, 44.1 meters, okay? So as the ball falls or the object falls, the more time passes, the more difference in position, more displacement is accrued and not at a linear rate, an accelerating rate, quadratically speaking, because t is squared. Okay, let's look at another problem. This time we're not going to drop a ball from the top of a tower. We're going to throw a ball upward into the air with an initial velocity. And that's what's given, the initial velocity of 15 meters per second upward. We're going to calculate first how high it goes, and then we're going to calculate how long the ball is in the air before it comes back to the person's hand, assuming it does. And all these problems, I have not talked about air resistance factored in its mathematical changes into the problems. So we assume that air resistance will be ignored in these problems. So again, the given and wanted lists are needed, but we must first choose a direction that's positive. Since I am initially throwing the ball upward, I'm going to make my initial velocity direction as the positive direction. So now positive is upwards, okay? Let's write down what we know. We know the initial velocity is positive upwards, 15 meters per second. We can assume that the initial position is zero. Why can we do that? Because we could set the reference position wherever we want. So I'm going to set it at the initial position of the ball in my hand. Now, for part A, we want to calculate how high it goes. Now, if you look at a trajectory of this, it would be just the first portion of the ball's trajectory. At the top, where it's at its maximum height, it's not moving because it's turning around to fall. So at its maximum height, we can say the velocity is zero meters per second. That's a pattern you will continue to see throughout this course. Now, the acceleration vector, which has a magnitude of 9.8 meters per second squared, points down. It points down, points the opposite of my positive direction that I've just defined earlier. So the acceleration will then be negative 9.8 meters per second squared. Now, what do I want? I want the maximum height. So I want the final position with these givens, okay? The first section of the ball's entire trip. Now, again, I'm going to also write down what else I do not know to help me decide which equations to use. I have not given any time information for this problem. So I want that final position, and I'm given this information. Without time, you know to go straight to the time independent equation, okay? If you can, and here we have all the other quantities, all both velocities, the acceleration, and one of the positions. We can find x final here, which are the same as x here, easily using the third equation. But I'm going to, again, so that people understand, I'm going to replace all my x's with y's, so that people can see that we're dealing vertically. There's no horizontal stuff going on, only vertical. Also, the initial position is zero, so I can place a zero there to simplify the situation. Now, when I solve for y, I'm going to subtract v0 squared to the other side, and then I will divide by 2a, and y minus zero, or just y, will be by itself. So for part a, this is the setup. v squared final minus v not squared over 2a. Now, the final v we already know is zero, so that's plugged in there, minus the initial v, 15 meters per second. Don't forget to square the velocities, guys, in the third equation. Then we divide by 2 times the acceleration. Yes, you must include this negative here. You must do it. It is negative for a reason. If we did not, we'd get a negative answer for our position, which would make no sense. It would be underground to that ball, and that would be silly. So the ball will reach 11.5 meters with the proper sig figs looked at here after it reaches its maximum height. So when it's not moving at the top to turn around, it's 11.5 meters higher than when I threw it. Okay, part b, how long is the ball in the air before it comes back to its hand? Well, we need to adjust some things because the final position is now back at the start, okay? So the final position is now known, zero meters. What's not known is how fast it's going at the bottom. Nothing like that is given. Some of you astute physics people will already determine that it has something to do with this 15 meters per second. We're going to look at that in the next slide, but not yet. Let's just assume we don't know the final velocity right when it comes back to its hand. We are asked for the time for the entire trip now. So it's the entire trip up and down. Okay, the acceleration is still negative 9.8 meters per second squared. I see no reason to adjust my positive direction even though it's only spending half the time going up. That's fine. The initial velocity is still the same. Now, we want time. So using the third equation again would mean nothing to us. It would not help us. We will have to use the second equation. Why can't we use the first one?  Well, you can't use the first one because you don't know the final velocity. You have two unknowns in the first equation, T and VF. I can't use an equation if I have two unknowns. But in the second equation, the only unknown is T. I know these other things, okay? I'm going to change them so I can prove that I know them. The initial position y naught is zero. The final position y is zero as well. So this simplifies quite a bit to just two terms. But you realize that we're solving for T and this is quadratic in terms of T. However, the constant term is not there. Thankfully, thankfully, if we were just solving this quadratic equation for T like we would in Algebra 2. And you can see that both terms have a T in them so they'll be factored out. So I can factor out one of the T's and then I have this equation. Now, by the zero product property, I can set the T out here equal to zero separate from this parentheses here and I can set that entire parentheses by itself equal to zero. When you do that, you get the following results. From this tiny factor here, T equals zero. I just get T equals zero. And from this more complicated one, I would set this parentheses equal to zero and move the 15 meters per second to the other side. It would be negative and then I divide that by negative 4.9 meters per second squared and the negatives would dissolve. So you get this positive fraction and you get this time. Now, the first time, meaning zero seconds, is meaningless. It comes from the fact that this is a parabola. The shape of the position curve is a parabola and so it spends, it has two instances when it's at zero and that includes the start. So we ignore that for now because of course it's at its hand when it starts. The other time is when it comes all the way back down to his hand and that's 3.06 seconds. So that's the quantity that's reasonable and makes sense according to the problem because it asks before it comes, how long is the ball in the air before it comes back to his hand? So the moment it hits his hand is right here. So that's how much time it spends in the air. Okay. Now, those of you who were interested in the symmetry of this problem will like this. We're going to consider again the same situation I provided a picture here for you. We're going to make some more calculations, okay? First, I want us to calculate how much time it takes for the ball to reach the maximum height, all right? We know the entire trip's length of time but how much time does it take for the ball to just get to the top? Some of you might say half. Let's see if that's correct, okay? Yes, that is correct, okay? Why does that make sense? Because the acceleration is constant, okay? Because the acceleration is constant that means that the situation itself is symmetric, okay? The entire trajectory can be cut into two halves and they look identical except one is in reverse if you were to play it back and that's the time it takes to fall. So I asked my students when I'm in class what this is and they all say it's half. They notice the symmetry, okay? So the symmetry is there. Exactly half the time it takes to get to the top as it does to go all the way back down to the bottom. When we have gravity is our acceleration vector, a constant acceleration downwards. So 1.53 seconds is our time for reaching maximum height. So what you can do always is you can find the time for the whole trip and divide it by two if that's something that works easier than finding the time using these equations for half the trip. All right, now part B asks us the velocity of the ball when it returns to the thrower's hand, okay? What is the velocity of the ball when it hits, right before it hits his hand? Is it related at all to the 15 meters per second initial velocity? Okay? Now we are going to have to modify our given and wanted tables from the previous problem or just make them again so that the final values are for when the ball hits this person's hand again, okay? So here's our tables. Given we have the initial velocity and the negative 9.8 meters per second squared because positive is still upward for me, the time for the entire trip is 3.06 seconds. We're looking at the entire trip for part B, okay? Velocity of the ball when it returns to the thrower's hand. The initial and final positions. Now again, you can use x's or y's. I'm going to use x's this time. Zero, okay? The final and initial positions here are the same and I set them as the reference of zero. So I want that final velocity v. So let's continue. The top equation. Look at all that you know. You know so much. All you don't know is v. Since I have v naught, a and t, I can use the first equation to find that final v. It's the simplest way to do it. Of course, you could use the third equation as well, but why? It's more complicated. Use the first one. There's no squares. It's just a simpler equation. So, we don't have to solve for anything. We could just plug and chug v naught plus at in there right away, okay? 15 meters per second for v naught. A is negative 9.8 meters per second squared, hence the minus sign, times the total time of 3.06 seconds. Boom, look at that. The velocity right before it hits this hand is negative 15 meters per second. So it has the same magnitude of the initial velocity, but the opposite direction, like we had hoped for. That is the true symmetry of these type of free fall problems, okay? We're going to look more at that symmetry later on, but for now, I'm going to leave it at that. The time it takes to get to the top is half the time for the entire trip, and if the initial and final positions are the same, the velocity at the bottom will be the same magnitude, but opposite direction is the initial velocity. All right, guys, keep this stuff in mind when you're doing problems that involve free fall. You have to choose a positive direction, making sure that the vectors that point in the opposite direction of the one you chose as positive get negative values. We just saw that in the previous problems. You can also choose a reference point for your positions that make the calculations the easiest. We did that in all these problems. Sometimes we chose where the ball was leaving the person's hand at zero meters, and in the earlier problem, we chose the top of the tower as being zero meters because we chose positive downwards so that our position would increase as it fell. And also remember that the magnitude of your acceleration g is 9.8 meters per second squared. All right, guys, there is the end of Unit 2 on one-dimensional kinematics. Thank you so much for watching. The next unit on two-dimensional kinematics is coming soon. For now, this is Falconator signing out.


All right. Hello everybody.  But I'm basically going to give you the best ideas that I got from the book. Of course, it's through my filter, through my lens, so I'm sure if you end up reading the book you might have other ideas that really stand out to you. These are what helped me is making a difference for me. And without further ado, let's talk about it. So the book that I've been reading is from an author named James Altucher, a L-T-U-C-H-E-R. And I've actually enjoyed listening to his podcast for quite some time. He is a non-entrepreneur, a kind of motivational type speaker, but he's also a comedian. So I think that's partly why I like his style, I like his voice. He keeps things light. But he also tends to exaggerate. So that's the part I don't like. He exaggerates whenever I hear something from him where I could go verify the results, I feel like he exaggerates a lot. So that's the drawback of his work and his writings. But if you set that aside and really take the principles and some of the examples that hopefully aren't exaggerated, it is inspirational and it's helpful. So let me just, what I'm going to do is I'm going to kind of look through the chapter headings. I'm going to tell you, I'm going to pick particular chapters that were, that made a difference for me. And then what the idea was. So the first chapter that really helped me was the 1% rule, the 1% rule. And the overall idea is this, if you improve 1% each day on a particular process that you do every day, then by the end of one year, 365 days by the end of that, you will be 78.877 37.8 times better in that process so almost let's just round it up 38 times better in that process than you were at the beginning of the year by a 1% improvement each day. So that's really significant. Now, on the other hand, if you decrease your ability of that skill or process by 1% each day for a whole year, by the end of the year, you will be down to only 3% of your original skill level. Yeah, which is, which is shocking. So that really inspired me to take more seriously this idea that we are always either strengthening our muscles, or we are atrophying our muscles in any area of life. Now, whether or not we actually if we don't do something do we really atrophy 1% every day. I don't know. I mean, that's, that's just a, that's just a, it's just a number and a way of thinking. It's not literal. Right. But it is true that if you improve 1% every day, you will be 38 times more skillful at that 38 times not, not, you know, you're not going to be three times better you can be 38 times better at that at the end of each year at the end of the year so that really inspired me to start looking every, you know, I know I'm probably a bit more organized and productive than most people, but I, this is my new habit that I'm doing. And I don't do it perfectly, but at the beginning of each hour. I don't do this when I'm relaxing at the evening or weekends but during the workday at the beginning of each hour. I take just two minutes, it really only needs to take two minutes to briefly think about my past hours activity. And how can I improve that activity by 1%. And then I write it down. Okay, that past activity I did. I think I can improve it by 1%. And what do we mean by improve by 1%. It could mean, is there a way to do that activity more efficiently. So a little bit faster possible. Can I do that activity with more thoughtfulness to the detail. How do I do that. Can I do that activity with a little bit more joy. So 1% improvement can be either in speed, or quality, or in a sense of virtue or values that we're implementing there. Okay, so that's what I do at the beginning of each hour I spent one to two minutes thinking about the past hour 1% improvement I write it down. I take another minute or so to say well this hour's activity. What can I do to improve it. Is there a 1% improvement I'm working on right now. And 1% is so such a nice. It's so small. It's, it's, you know, it's so small like for example. If I take, if I usually take 10 minutes to do something. Okay, let's just say 10. Let's just say one. Yeah, let's say one hour. I usually take one hour to do something right one hour 60 minutes time 60 seconds is 3600 seconds is one hour right a 1% improvement would be. Now I'm going to take 3564 seconds instead of 3600 so I mean, just as a, just as an idea, right, which means I'm, how can I shave off 30 seconds. It's like how can I shave off 30 seconds. If I did one at one hour. How can I, how can I save just 30 seconds. One idea might be, have I even written down the process, the step by step process for what I'm going to do this out. Have I even written it down. If I haven't even written down the step by step process, I can't even analyze it. And how I make it more efficient. That's why I write down all my step by step processes.  I literally write down my step by step processes. If I'm preparing a course, this is, this is the first session that I prepare for my beta course this is what I do. The next 15 minutes I do the following the next 15 minutes I do this blah blah blah, and I have a process for my practice group. Okay, what do I do. How do I prepare my practice group I open up this, I open up that I open up this, and then what's the structure of the group, I do this I do so I've written down everything. All my processes. As much as I can. If you have that. Is there a process that you do on a weekly basis or a daily basis that is hard to keep in your head. I mean, yes certain processes like okay there's only two steps here to write down, but I feel like even if there's three or more steps. If I just take the one minute to write it down. It's helpful to not keep it in my head. So, therefore, therefore I'm able to start making 1% improvements on it to say oh yeah what's the 1% for this step is there 1% improvement. And maybe I should write down that first step is really five micro steps. I mean write down the five Microsoft so I can start making a little bit improvements. And yes over time. It's not like we have to read every word of our steps, of course you met you over time you keep looking at it again and again and again, become so familiar. Until you take a moment every once in a while go hmm that one micro step is there a 1% improvement there. I mean this is how factories become more and more efficient. Isn't that right. The Toyota method. Right. Kaizen right continuous small improvements. Right, so this is how factories become more efficient like, let's tweak the machine just a little bit more. And if we take the machine a little bit more our system you are your process your day as a machine. Your day is a machine. It's a series of systems it's a series of processes, it might be a very messy machine, because you haven't really looked at it carefully, but it is a machine. But if you don't have it, if you haven't written it down you can't, you can't know the structure in the system therefore you can't improve it. But once you've written it down you go okay that one thing I can prove it just a little bit. And if I improve a little bit guess what every single time I do it. I'm saving 30 seconds in so 30 seconds is nothing no it's not nothing. If you do that process every single week. That's 50 times 30 seconds. Right, and every single time you improve it you can prove another 30 seconds okay now you're improving you're saving minute, and it's not just that you're saving up George come on give me a break 30 seconds no big deal one minute.  So 1% improvement I really found that helpful. And that's what I'm starting to do every, every time. Okay, so the next chapter. Let me know. Are there any questions this is makes sense. We are, you know we're a small group here so I do what welcome you to unmute if you want to say, you know, 1020 second reflection, does that make sense. Any questions you have. Yes. So. Yeah, so Peter thank you for your comment there. Yeah, so 1% approach would make it more healthy instead of instead of so you know trying to improve yourself dramatically every day it's, it's, it can be too stressful so I think I like the 1% improvement idea. Every process I do just 1% improvement just 1% if I just keep doing that every time then, even though I don't do the task every single day of the year I won't I won't make 38 times better by the end of the year. If I become one and a half times better by the end of the year. That's great. Because in 10 years I'll probably become 10 times better. Do you see what I mean. So, yeah. And Utah has great ideas like it's kind of like learning one new word a day in a foreign language 365 words a year that's, that's more than you would have learned. Try to figure yourself out and try to learn 300 words in the month and probably forgot them all or whatever you know but it's like, it's, you know. Yeah, very good. So, and Wendy says it's like lifting weights, you add one pound. You know, improvement over time increasing one pound at a time you get stronger more fit. Absolutely. Absolutely. One pound seems like it's nothing. It is something because your muscles understand what that means and it gets get stronger so great examples okay so the next chapter that made a difference for me was 10,000 experiments, and this is really the core of his book. Okay. So the 10,000 experiments idea really came from the Thomas Edison story. You never heard of this this true true story. These are facts right you can we can, we can look at history Google Google this. So, this was really when Thomas Edison was making the storage battery. And he actually let me see here, let me I actually wrote a blog post about this. And, and you could, I just want to show you. So I actually funny thing was I actually wrote the blog post before I read the book. So, so it just it's a synchronicity, but, and I actually did the research about the Thomas Edison story before I read the book. Okay, so, Thomas Edison, of course known for the light bulb. He actually constructed 3000 different theories in connection to the light bulb, each of them felt like reasonable to him, apparently true, but only in two of the cases to out of 3000 that the light bulb theories work. That's incredible. How many, how many thousands, how many hundreds of experiments have you done. I never feel you want to become great at, you know, and this is this is something that, and let me just keep going and then I can stop the screen share. This is Thomas Edison worked on the storage battery, which actually created more wealth for him, right interestingly right. He got richer from the storage battery than a light bulb a lot of people don't know that. Okay, so the storage battery he worked harder on this thing. Over 9000 experiments. And it's still he still hadn't found the right answer. 9000 experiments.  And of course, his friend said, isn't the shame so much effort, you didn't get any results. And then Edison said no wait wait what are you talking about I've gotten a lot of results I have several thousand things that don't work. I don't have to do that same experiment again because I know it didn't work. So, this is something that I see in my clients all the time. The client said George, I launched this online course and it didn't work so your your teachings don't work. Did I tell you to launch one online course and then therefore it didn't work. No, I mean if you know anything about me you know I'm all about experiments and you know you can, if you watch me, watch what I do, and not just what I teach but what I do is I launch a course every single month and I've done so for years.  I can only muster one course a month, and some of you can only muster launching one course every three months and that's okay too, especially if you're really busy, right. But 12 courses a year is only 12 experiments a year. Actually, before I launch a course, I also do survey, I survey my audience out of these.  First I brainstorm, you know, at least five to 10 topics before I decide on one. You could say I'm already experimenting with five topics, and then 10 topics, and out of the 10, I then narrow it down to three that I think based on what I know of my audience they probably would like these three best. And then I survey that. So that's another experiment. So really for every single course. It's like I do five or 10 experiments for every course launch. So let's just say five that means really each year. If I launch 12 courses I have 60 experiments a year. You see what I mean, I do 60 experiments a year. And so when someone complains to me and says George I launched, I took a course of yours about creating and launching courses I launched one course and nobody bought. And then so therefore your course doesn't work. I'm like, are you serious. Did you actually study the course, because I told you to launch a lot so that you can see which one worked and you didn't even take a survey. This is literally someone said to me this recently I launched the course didn't work. I'm like, did you even take a survey.   Or, if you say George I, I, you know, I, I had three exploratory calls with potential clients and none of them wanted to buy my service so I don't think I should be in business. Three experiments. Are you kidding me. Okay, so basically what James Altucher inspires us to do and you know based on the Thomas Edison story is 10,000 experiments. Now why 10,000 experiments now.  You need 10,000 hours of practice and not just practice deliberate practice. What's deliberate practice deliberate practice is like carefully practicing a specific segment of a skill micro skill practicing a micro skill. 10,000 hours but for in those 10,000 hours, you are practicing specific micro skills to get better at the micro skill and then practicing the next micro skill get better at it and then and then connecting those two micro skills together to have a better better better bigger skill. That's what deliberate practice means. And James Altucher, the whole book is called skip the line. Okay, skip the line is what the book is called which I really don't like the idea.  The idea is basically the more but benevolent way of looking at it, ethical way of looking at it is, how do we do things in the most productive manner, in the most efficient matter, and not just in the way that everyone is doing it without thinking. What he means by skipping the line is like, if someone if everyone's waiting in line when they're really there really is no need for a line. That's what he means there's no need for a line.  That's what he means. So it's like, don't just follow society's rules are you're supposed to do this you're supposed to get this certificate and then that and then this and then this and this and this before you can call yourself and then you 10,000 hours of practice before you should call yourself a master he says wait a second. There's a more efficient way of doing it. It's called a 10,000 experiments rule. Now, ironically 10,000 experiments probably takes longer than 10,000 hours, right. But but but what he's saying is that really if you if you aim for several hundred experiments, even 100 experiments is more than most people in your field are doing. So if you aim for 100 experiments, you're going to already be one of the probably the top 10% in your field, because you have done enough experimentation in your field to understand what works and what doesn't work. Most people in your field don't do the experiments, they study, they read books, they take courses, they may have gotten degrees. And yes, those study courses and books are about people who have done some experiments. But to do your own experiments allows you to actually learn much better than by reading a book. And and when you design, of course, you read books, of course, you can take courses, of course, you know, that helps with some shortcutting with or that helps with some understanding of what the history of your field is so that you don't have to make the same mistakes over and over again. But even after your study, if you don't do your own experiments, you won't come up with new ideas that make you one of the best in your field. One example of experiments is the way I think about content creation. Right. Every single time I make a video, or write an article, I'm making an experiment. An experiment is here's an idea I want to share with you. Let's see if it works. So I don't attach myself to Oh, did this article go viral. Did this video get liked a lot. No, I don't attach myself to any of those metrics. I don't attach those metrics so I can look over time which experiments work. But every single thing I put out there is an experiment. So by this point, I have made 1000 videos. Yes, I've made more than 1000 videos and written more than 1000 articles at this point. This is over years, of course. So I have done 1000 experiments and not surprisingly. My business is doing very well. And I really have seen that when I put myself out there hundreds of times, looking at them all as an experiment is saying I want to do this idea work. And by the way, experiments. Do most experiments succeed. No, most experiments fail. But if you look at failure from a larger perspective, what is failure. Failure really should be looked at. So there's, there's two, two ways of making mistakes. Commission and omission. Two ways of failure. Commission, meaning I did something and I, and I failed or I made a mistake. Omission is the true failure that we should all be more concerned with, which is I didn't do it at all. So if I didn't do it at all, I wouldn't have even known whether that would have worked for me. Okay, let's say, let's say that the lottery was much easier to win, which, by the way, in your career, your career and the success of your career is like playing the lottery, except it's much easier to win. So lottery in the United States is something like one out of 15 million chance of winning the jackpot, something like that, right. So it's next to impossible, right. You might as well be throwing money away in your career. It's more like one out of 1500 is the odds. Really, literally. So by the time you make your 1500, sorry, 1500, by the time you put out 1500 articles or videos. Okay, let's just say with with content, it's like 1500. That's what I'm going to say to you. If you write 1500 articles and videos, I can almost guarantee that you will become a success in your field. I can't guarantee it, obviously. But I've only done about 1000. And I'm already quite successful in a very competitive field. How many articles have you written? How many videos have you put out there? Probably not even close to probably not even 150.  Probably. Really, I would I would bet on I would actually invest and bet on that 1500. Now, how quickly can you do the 1500? That's up to you. That's up to you. If you do three per week. Okay, there's that's 150 per year. If you put out content 50 weeks, if you put out content 40 weeks in a year, that's 120 in a year. So that's 10 years before you get to top of your field. Or at least have your business be a success. You put out five a week when I started I put out five per week. I did that for six months. That's the number that that calculates out to 265 100. Yeah, about what is it 26 times five. So yeah, I did about 130, you know, 130, right out the gate for six months and that really got me some initial traction people started noticing me. I've been doing only three a week and then actually somehow count the calculations. I know I have 100 1000 more than 1000 well over 1000 videos on my YouTube so and I usually wrote, you know, I always wrote a small articles anyway. So, however, the calculations work out I've been doing videos for a long time. So more than just five years has been it's been a long time so. Okay, so content. I'm going to give you the 1500 number as the number of experiments that will make you your business success for sure, of course, all the way, all the way there, you will be finding success along the way, but 1500 aim for that. Now, for your offerings for your online courses, or for your coaching packages, or for the way that you describe your consulting offer, whatever this that you offer as a service or product. I'm going to give you the number of 150. If you do 150 experiments of what you offer. You will find traction, I can almost guarantee you, I can't guarantee, but it's very probable that 150 experiments will get you to be like, Oh my God, this is my career is going to my career is going to work in this business is going to work out I have solid confidence that this is going to work. This is we have only done like five experiments. So each experiment is like, you send out an email with this particular description, you've written out this is my coaching offer, my consulting offer, you've posted it on social media. Every time you, if you posted on social media and send out an email and do it on all social that's only one experiment. Yes, that's only one, because every time we describe your coaching or consulting offer that's one experiment the way you wrote it. Now, sleep on it. Next week, you write it differently. So okay, I know I could describe my coaching offer differently. Let me sleep on it and just write it. Don't look at the original version. I'm going to write a totally different version. Of course, you're going to have some things the same. I'm going to try to write a different version next week. That's a second experiment. A third of experiment might be okay I'm going to try launching this course. That's a third experiment. I'm going to try launching this group program. That's a fourth experiment. I have definitely launched more than 150 experiments for offerings courses, the way I describe my, my coaching, the way I describe my group program. I've done at least 150 over the last, well, 11 years of business. And not surprisingly, I'm quite confident that my business will continue to succeed because I know out of those 150. There's about 10 that work really about 15. I would say that work really well that I can continue repeating those 15 over the course of my lifetime. Of course always experimenting more see certain things that every year I still experiment every year. If I ever launched, like I said 12 courses, I would say probably now that I've done so many, I would say out of the 12 courses, every course does okay. You know, it's like, ah, it's okay. And out of the 12, about three of them do really well, do really well, and that's those of you, all of your affiliates here watching this. That's when that's when your affiliate payment goes up each certain months like how come the filling was there that month, because that course did really well. Okay, and then certain months it's like, only a few dollars, whatever. Yeah, it's a, it's a so so month. One of my experiments that didn't work out as well. Right. So that's the assignment for you is for your offers 150 offers. How long will it take you. Well, depends on how many offers you put out there every month. And now you could realistically only put out, not more than two offers a month. Really, I mean, because your audience will be like what you're offering something again, oh yeah something again. So up to two offers a month is possible one offer a month is pretty common. So you really only have 12 to 24 experiments a year that you can do this. So let's just say 12, let's just say 18 is the average that you do so sometimes you do one sometimes you do two a month. The divide by 18 is it's a eight year process. Now, obviously it's a Georgia have to wait eight years before I can start making some money. No, obviously not. When you start when you start making an offer, each year, let's say you make 18 different offers or 12, let's say 12, probably one or two of them are going to do pretty well. Like, Oh, I made five 10,000 20,000 on that offer. Okay, or 30,000 whatever well means for you. And then the other, and then there's maybe another three, I did okay, I made, you know, two five 10,000 on that one. And then the others five however many left or left six seven eight whatever are going to be like God made 500 to 1000 on that offer. You see what I mean. So, you need and of course as you learn over time. Oh, these offers really work. You're going to be able to say well let me do more of those offers. So, so, so essentially doing experiments. And the other thing I'm out and I'll close off with this. The 10,000 hour rule he says the problem the 10,000 hour rule is that you master something for 10,000 hours you might realize you don't want to do it anymore for the rest of your life. You might get tired of it. And that does happen. It's like why are you spending so much time mastering one skill set when you have so much possibility within you that you should be experimenting with a lot more different things. So the experiment more, you actually respect your potential. And you activate your potential by doing a lot of experiments and seeing which one worked, because our calling is the intersection between our skills and passions, and what the market what the world wants from us. And in order to find the intersection, you have to experiment. You can't just be practicing one thing become a master at it and decide oh maybe I don't even passionate about it, and maybe the world doesn't even want that much. You've got to experiment with a wide range. So, I can't believe that that was, well those are the two most important chapters of the book out of the entire thing but in the next session, I'll finish off the book with the other some of the other ideas that help this is inspiring. This really made a difference for me just in thinking in terms of 1% improvement and experiments and doing more experiments. And, and therefore, experiments you don't attach yourself to it just I'm just an experiment and most experiments fail. So don't be surprised when you put something out there and nobody buys because that's normal. That's normal. That's normal. You have to do the next experiment now. I wonder which is going to be the one out of 10 networks, or one out of five, or as you get more understanding of your market, one out of three networks. So, I hope this helps and go forth. Do your 1% improvements and do your experiments. And I'll see you in the next session or you'll watch the replay later. Alright, take care everyone. Bye for now.


All right, it is time to announce the winner. Lots of great submissions, but first let's go with the honorable mentions.
