                                                            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?

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.

                                                                                                  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.
