The Gaussian-School of Higher-Arithmetic (1831, updated 2022); tutorial #20.

The writing was on on the mathematical wall, before the first ape became a "man".

In the arithmetical world of rotation, we can use simple everyday things in the world around us to give us a "wake-up-call" as to the fact of rotation.

Here we see the hilarious spectacle of Peter Bensenyei in the fabulous 660 kg +/-10g Extra-300 demonstrating how he can allow gravity to get a hold of him without first bothering to make a 180 degree rotational chandelle over the top. In the end he gets a huge involuntary rotational shock change in direction. Bensenyei experiences  an involuntary pitch rotation rate peaking at over 6 quadrants per second.  With a negative airspeed, physics cannot describe his silly lump as any kind of an "aircraft" at all.
