Why a record spins at 33 1/3, 45 or 78 RPM...

This is a very pressing question, since the media format is being a resurgence in the late 2020's. We ask, and answer the great question of life, around why records spin at the rate they do. Which for additional "we are indeed in the matrix" details - 33+45=78... OMG.
This video stars Dave Mathews "Gadget Guy" wearing a T-Shirt with three numbers that frequently gets him confused looks from onlookers.
John Behrens who makes Tesla coils in his spare time and is a wizz at frequencies.
Tinic Uro who builds circuits for fun and profit
Finally, Paul Belger who has built some of the most amazing large scale art that the Playa has seen. In this video he mostly snorts and mumbles, which is ok based upon the amount of wine and steak that we consumed.
