- Gravityloss 9y agoIsnt it related to that rotating widget demo on the space station? Terry Tao had a good explanation of it.
- imglorp 9y agoWould you have a link? If you're thinking of the Tennis Racket theorem, I don't think it's the same thing as chirality, is it? The special tippy-top would erect itself only when spun in one direction but not the other. > The tennis racket theorem asserts that when rotating a rigid body with three distinct moments of inertia, the rotation around the axes with the largest or smallest moments of inertia is stable, but the rotation around the axis with the intermediate moment of inertia is unstable. src: https://plus.google.com/+TerenceTao27/posts/e3GLg4Ki4dj https://plus.google.com/+TerenceTao27/posts/e3GLg4Ki4dj
- Gravityloss 9y agoYes, https://news.ycombinator.com/item?id=14125097 https://news.ycombinator.com/item?id=14125097 Does not explain chirality... I didn't watch the original video so closely, sorry.
