    • I would expect so, but I think you are right about the speed being key. I suspect a very fast rotation before you can really see a "bend". The water molecules move extremely slow in comparison to light, so it's very easy for the rotation to overcome this. Also.. Absolutely love your channels, I hope you can keep doing what you do as long as you feel you can.

    • I think that whatever apparatus you constructed to hold the laser emitters while rotating would overcome the tensile strength of its material before you could observe a perceptible curvature of said lasers... unless you did so on an enormous scale. If you put a field of light-scattering dust around the planet and recorded the laser light interacting with that at a fraction of a light-second's distance from the emitter, it could be done. Very close to the emitter, you would notice nothing, but in low orbit, you'd notice a slight bending, and in geostationary orbit, you'd have about 120 milliseconds between the emitter and the observed scattering. You would need extraordinarily sensitive imaging equipment to observe such an effect, and the farther the laser traveled through such a cloud, the more it would scatter and the less perceptible it would become.

    • This is the basics of communication and it is always worth reminding from time to time. All communication comes with a whole bunch of implicit things like vocabulary, point of view, historical info, know-how, etc that are considered common knowledge and left untold for the sake of efficiency. It takes a lot of effort to second check them and make sure they are really common. So unless you have absolute certainty that the other party is a complete moron and is not worth talking to (then why are you talking to them in the first place?), you should always consider that this person is not stupid. So when what they say doesn't make sense to you, your first reaction should be to trace back their arguments and try to find out at what point their reasoning differs from yours. Then it's relatively easy to explicitly tell them so you can review what was truly agreed on and who is right or whether both views are just different wordings of the same thing.

  • Feels like you forgot to mention why the water travels ”ahead” when spraying inwards and ”behind” when spraying outward. The answer is simple geometry, when spraying inward the ”radius” decreases so the droplets travel faster than the shaft (since they have the tangential velocity at the tip). When spraying outward the ”radius” increases and the droplets travel slower than the imaginary extension of the pipes. Sure, just saying ”look at the resultant of velocities and remember that unless acted on by a force everything travels straight” explains the phenomena, but I feel like the simple geometry aspect explains the ”optical illusion” which really isn’t an illusion, the water is really shooting out in front and lagging behind the pipes, if you were to place something there (in the same rotational reference frame) it would become wet, so not really an ”illusion”.

    • The water droplets are 'drawing' a trace which looks like it's ahead or behind the nozzle, but they're just moving at an angle that changes relative to the rotating nozzles. The terms 'ahead' and ' behind' are not relevant in this dualistic system where one part is rotating (nozzles) and the other moving linearly, it's just the trace that gives us the false impression, while our brains fail to decode the movement of each individual droplet. Our brains also fail to decode other people's views and feelings when we assume to have authority on some subject. I wouldn't say any nation in particular exhibits this feature, but progressive, intelligent and educated folks can be arrogant, even without knowing it.

  • First Sprinkler: Once the water leaves the spout there is no Coreolis force to accelerate it tangentially that’s why it lags behind the sprinkler arms as it moves radially outward. Each particle has the same tangential velocity as it had when it left the nozzle. The drops would have to accelerate tangentially (via Coreolis force) to keep up with the arm as the drops move away from the centre of rotation. Once the drops leave the nozzles they travel in straight lines. Second sprinkler. This is the exact opposite of the first case. The flow appears to lead the arms because the water has the tangential velocity that it had when it left the nozzle. There is no Coreolis force to slow the water’s tangential velocity to match the arms. Since the tangential velocity at the nozzle is bigger than nearer the axis the water leads the arms.

  • Hey Destin, video request! In the book "Surely you're joking Mr Feynman" at the end of the chapter of the same name, Feynman describes an experiment he did with spinning water pipes. In the experiment, he sets up an S shaped pipe and forces water through it and asks, which way will the pipe spin? Then asks the question, if instead, the whole thing were submerged in water, and we suck water through the S shaped pipe, which way will the pipe spin? Unfortunately, the chapter ends with him breaking some Princeton equipment and we don't get to find out which way it spins! I think this would be an awesome follow up video to make!

In the case of two political ideas diverging from each other, there is no 'true' frame of reference to define which is 'positive' and which is 'negative' (or constant). In the case of a political movement with 'acceleration' (I dunno the apt analogy for that, support growing for it maybe?) then at that point we can say one idea is steady state while the other is changing. In the case of the video experiment, the object which is accelerating is the tube apparatus (not the water). If I was (politically) water, I would be correct to say that those darned water pipe party members are always changing, I'm just going about my business! :) If I was part of the tubing party, I'd have to say, yeah the water party isn't 'accelerating backwards' but they're not keeping up with the times!

  • Here's a way to intuit this result: If two objects are in circular motion with the same tangential velocity, but with different radii, the one with the smaller radius will have a higher angular velocity, which means it will complete the circle in less time. Think of a helicopter blade. The end of the blade has a much higher tangential speed than the base even though both parts of the blade complete the circle in the same amount of time. If you decrease the radius, but keep tangential velocity the same, you get a greater angular speed, which explains why the water moving inwards leads, while the water moving outwards trails.
