    Why didn't he call it 'Bendik's Disc'? Did he fear that it would be confused with William Bendix (who usually played guys of limited intelligence), than whom Euler is much cooler?

    If u think of the universe as a 3-dimensional support vector machine, or the gradient of a neural network, then physics is the backpropagation optimization of gradient descent. In neural networks, to find the local minimum, you take steps in each direction, and if you pass the minimum, you take a smaller step back, and then you make a smaller step forward again and back again, again and again, until it reaches the minimum.

    Love you VSAUCE!

    I could be wrong but I feel like the tilt shown in the rotating disc will not be inherently 90 degrees away from the vertical force, but will depend on the angle of the component vector formed. So if you blew very gently it would be closer to 70 degrees or something along those lines, or if you spin it even faster it would also have a lower degree tilt relative to the source of the impulse applied.

    If you could spin it in a vacuum chamber then quickly put the lid on and pull a vacuum would it spin for much longer ?

    At eight years old I found this and never knew why? It was amazing! I never knew why? But know I does. It's fantastically simple but only if you know the why :D . Physics is amazing but not just that the world is amazing. thank you for teaching everone easy to understand and ease to do science or experiments for me n my kids to do. Thank vsauce
