Draw a clock: Difference between revisions

The audio, On the Teeth of Wheels by Beat Frequency, (used with permission) is a sonification of the [[Stern-Brocot sequence#Quackery]] It was discovered independently by Moritz Stern (1858) and Achille Brocot (1861), along with its visualisation, the Stern-Brocot tree. Brocot was a watchmaker, and used the sequence to find best approximations for gear ratios.

This sequence is used by clockmakers in choosing suitable gear sizes for the clockwork, and features heavily in theThe book "A Treatise On The Teeth of Wheels, Demonstrating The Best Form Which Can Be Given To Them For The Purposes Of Machinery; Such As Clockwork And Millwork, And The Art Of Finding Their Numbers." postdates the sequence, being written by Charles- Étienne- Louis Camus, and translated from French to English by John Isaac Hawkins in 1873, but shows a method relying in part on guesswork to achieve the same end.
