    My off-the-cuff take on the questions: 1) Cylinder contains a second cylinder (or even just a ballbearing). The "sloshing" of the inner roller is what upsets the outer. 2) Depends on the gear. Anything from move(drag!) backwards to move forward, depending on how much wheel movement is caused by crank movement. 3) Second lap speed needed to *double* first lap speed? Fast. Very fast. Warp factor Plaid speed. And even then only if your stopwatch is slow. 4) Train: Any part of the wheel that extends past the rolling surface, i.e. the flange on the wheel. (plus anything mechanical int he engine that rotates fast enough...)

    Between 4:16 and 4:29 (at 0.25x speed, of course), look to the left half of the chain to understand the phenomenon. This is because the beads on the right side bunch up to make it look like two interlocking parts of the chain to offer a distorted perspective. You'll waste a lot of time if you look to that side. Just FYI.

    1 - can't be bothered to test which liquid it is, but it's a liquid 2 - surely it depends how hard you pull the string, how grippy the tyres are, how heavy the bike is... 3 - I would assume (1+3)/2 = 2 means you'd have to go 3 times faster, but I'm expecting I'm wrong 4 - the wheels, I reckon this was the easiest

    8:47 it's technically misleading to say it's under 1atm of gauge pressure upon uncapping, but rather only 4E-4 atm. because in this case only the partial pressure of CO2 in the atmosphere is relevant. opening a soda bottle into our atmosphere is as good as opening the bottle into outer space where the drink going flat from CO2 loss is concerned. you can confirm this by opening the bottle, recapping it, pumping atmopheric air into the headspace back to 3atm, then shaking the bottle. gauge will rise to 6atm despite the dissolved CO2 being only 3atm.

    If you read YiJing , a very old Chinese book, and have mastered its essence, your understanding of the world and everything you’ve learned will be overthrown. Two weeks ago, my wife let a Shifu, who is a master of YiJing read about her life. He asked her for some information like her birthday, birth place and so on. After a few minutes, that Shifu asked my wife if her dad had already passed away. My wife was like shocked cuz it is true that her dad died three years ago....after this experience, I changed my mind and attitude of YiJing and what a Shifu does. I used to think all those stuff are superstitious, but now....

    Can you clarify? Does it mean it is impossible to predict, or very hard with today's technology? Going back to the theory of a system that knows everything, and assuming a future computer that can compute to infinite precision. Would we then be able to predict even chaotic events?

    This is the first convincing "thing" I have ever seen on the possibility of climate change. A very good case was made however I do believe the role of water vapor was down played. Also the cause of climate change was blamed on a small amount of Carbon Dioxide. The cutting of the rain forest is playing a bigger role in changing of the climate. The rain forest produces water vapor and reduces Carbon Dioxide.. NOT addressed in this presentation. IF global warming was real problem we would be looking at alternatives to reduce the temperature of the planet. To fight the ice age there was a plan in the 70's to drop coat dust on the snow in the plains. I am sure it would have worked. Spread some ashes on the snow in your yard sometime and watch the snow melt. If it is getting too hot reflect the suns rays back into space.

I am doing Engineering in IIT-D. Lol my studies did not help in the last ques. Edit( after watching the solved video) : 1. ans was correct. 2 I should have said it depends as I knew about Torque. 3. I actually solved it in 15 sec. 4. I didn't knew train had grails in them. I just thought that the bottom point is stationary.

    bottle geysers for the same reason boiler explosions are so deadly. As soon as a small openiong in bottle or crack in boiler occurs the adjacent compressed liquid can immediately flash into vapour and then the next and the next until a chain reaction of flashing occurs right through the liquid until all the pressure has dropped to atmospheric. With hot water in boilers obviously more of the liquid will flash off. This is the reason why shaking a can of pop then trying to cut it open will cause a mini explosion that rips the can open.

    you could put magnetos in it and try to run it like an alternator or something. This array seems to utilize the natural magnetic flow by compounding the fields, it uses the natural toroidal dynamic in a type of broken symmetry, i guess. If you're creating heat you're wasting energy. Couldn't it take up the energy it gives off, if it alternated current? I still don't understand wireless energy transfer.

    So is the system deterministic but the problem is that we don't have sufficient resolution (yet) to predict the behavior of chaotic systems, or is it that we would need infinitely fine resolution for such a prediction and thus it can't ever be done? And if so, would it not be theoretically possible to get close enough that the error is no longer a significant factor compared to the lifetime of the universe?
