A.K.A The Oiler’s Disk
[By staff reporters]
A Euler’s Disk is a scientific educational toy, used to illustrate and study the dynamic system of a spinning disk on a flat surface (such as a spinning coin), and has been the subject of a number of scientific papers.
The apparatus is known for a paradoxical dramatic speed-up in spin rate as the disk loses energy and approaches a stopped condition.

Kinetic Energy: In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

Euler
I first read Euler’s Elements of Algebra when I was 12 years old. The irony is that although Euler was better at algebra than almost any professor of mathematics today, he was also misinformed and wrong about his conclusions with respect to series.
Euler erroneously decreed that S = Lim S and this rot has permeated all of mainstream mathematics.

Euler made many mistakes aside from this. It’s a shame because some of his discoveries are useful.
He contributed exactly zero to calculus. His ideas on infinity were toxic: not only was he wrong but the theory derived therefrom has gone nowhere since his time. Infinity is a junk concept that has no place in rational thought. (edited)
