@@airsoftalgerie3302 Actually, it would be the U.S. Secret Service. I believe that it is not illegal to _have_ it. It would only be illegal if you tried to spend it as legal tender, and it was illegal to make it and even to produce a 1:1 image (i.e. while making the stamp or mold).
Coming from someone who majored in physics in undergrad, this is by far the most succinct, easy to digest and simply mind boggling explanation of the law of conservation of angular momentum that I have ever seen! I always thought it was some fundamental magical concept that the universe keeps track of. The idea that relationships and causality are intertwined but not necessarily predicated on one another was amazing. Hats off to you sir!
I remember in high school asking "why" certain things happened, and way too often I had to explain that I know the "law" but didn't understand what actually causes the things that laws predict. Now I think that I could have explained my curiosity better to others. Causality as a concept will hopefully help me with this all in the future. Honestly, I think this is a video worth watching every once in a while. That's just to truly understand what Michael is trying to tell us.
I think the experiment shows more than just the law of conservation of angular momentum. He doesn't dive into it because it would be too complicated for his audience, or maybe just too much info for one video, but really his experiment with the spinning wheel also helps explain the relationship of force and momentum, i.e. how a change of momentum over time equals a force. He shows how pushing the wheel down slightly changes where the edges of the wheel are, therefore altering what the angular momentum is, and then relates that back to a torque that causes him to rotate. Furthermore, he shows how important defining and isolating systems is to understanding the laws of physics. By isolating it into two sub-systems, just the spinning wheel and him/the chair, when he starts spinning its clear how the wheel must have caused it. Even before he explains it at 18:45, you know it must have been from the wheel just due to the isolation and a lack of external forces. And this to me shows in a broader sense how changes within a system always result from interactions or changes relative with other internal parts. **Its not a magical concept that the universe keeps track of, its interactions within the system. ** You could have defined it differently but its the same result. Like say instead we looked at the wheel axle and analyzed how him rotating it created a point of contact between the handle and the spinning part of the wheel shaft. At that location there can be a force from him flipping the wheel and the spinning part is also able to impart a torque on him. You could even look at the fibers of his muscles as they have a force placed on them and how that happens at every point of his body eventually getting to the axle of the chair. No matter how you slice it up its not a magical law of conservation as much as saying inside an isolated system nothing can change as a whole, so any internal change results in a change somewhere else. Once you start looking at things and realize how everything is constantly interacting at a microscopic and macroscopic level, the laws of physics are less explaining *why* and instead are more like shortcuts to explain *how* physically everything is occurring. Instead of wasting effort computing at a bunch of different points and interactions we can use our knowledge of momentum to say regardless of what interactions happened, we know this for sure, and that makes otherwise complex problems simple, or at leat gives another tool. And I think by deconstructing the wheel experiment a little bit more and breaking up the system in another location makes that become even more obvious
No. It breaks laws so obvious we didnt know they were even needed. Is kind of ok with laws of physics. Since the laws of physics are now quantum physics.
@@jorgepeterbarton the physics of the double slit experiment are actually very simple and well understood. It doesn't really "break" anything, it just exposes an exotic branch of physics
I've realized what makes Vsauce so captivating for us science people He presents in a manner reminiscent of a kids' show, but doesn't cover topics of any juvilinity. Usually.
Just take a moment to appreciate the fact that his guy propably thought about this joke before and waited over a year to be able to pull it off. Respec.

Two and a half years on, why did YT suggest this? Doesn't matter. I grabbed some books, sat in my office chair, and played with angular momentum. Made me smile. Thanks, Michael. :)
@Enlarged PP Please understand that zbot473 got the joke. He is making a statement of his own which is not a joke; he is providing his own opinion on the subject which the joke was addressing.
"He was very malnourished and a psychology book was found next to him. We also found a philosophy book in the toilet. What does this all mean Sgt?" "...Logic."
Yeah, I've been so bummed out over the last few years because... - Vsauce basically went pay to view... - Vsauce2 became a card/bar room tricks channel - Vsauce3 well...I guess Jake is having an early mid-life crisis. (I love Jake! I hope he gets his groove back soon!) And now, here we go! A proper Vsauce video from the OG Vsaucer himself! Woohoo! :D Now...I hope this isn't just a one off! :/
This video feels way more "creepier" after watching Vsauce's "Why are things creepy?" video. The Vsauce doll near the beginning, the dark ambience in the light and 6-cm-tall-nail experiment and the person(Jake?)-ish figure behind; all contribute.
