I Got Arrested

I got arrested today for walking out of an art museum with a painting.
I’m just so confused because earlier when I asked the security if I could take a picture, they said “yes.”

George Graham

Died 20 Nov 1751 (born c. 1674).Eminent English watchmaker who was first a partner with, then successor to Tompion's business. Graham improved Tompion's cylinder escapement. In addition, he invented (c. 1715) the dead-beat escapement (in which the escape wheel remains stationary when not moving forward.) Using these two developments together, Graham's timepieces ran with an accuracy unsurpassed for more than a century and a half. He also made astronomical devices for Edmond Halley, James Bradley, the French Academy of Sciences, and Charles Boyle, 4th Earl of Orrery. For the latter, he designed a clockwork model showing the motions of the planets around the Sun, thereafter known as an orrery. He invented a beam caliper with a micrometer screw.
