He was the first one in America to put spider web as cross-hairs in the focus of his telescope. He is generally credited with inventing the vernier compass and possibly the automatic needle lifter. He was professor of astronomy at the University of Pennsylvania. Benjamin Franklin consulted him on various occasions. For Thomas Jefferson he standardized the foot by pendulum measurements in a project to establish a decimal system of weights and measures.

Bowling Team

Two bowling teams, one of all Blondes and one of all Brunettes, charter a double-decker bus for a weekend bowling tournament in Atlantic City. The Brunette team rides in the bottom of the bus. The Blonde team rides on the top level. The Brunette team down below is whooping it up having a great time, when one of them realises she doesn't hear anything from the Blondes upstairs.

She decides to go up and investigate. When the Brunette reaches the top, she finds all the Blondes frozen in fear, staring straight-ahead at the road, and clutching the seats in front of them with white knuckles.

She says, "What the heck's goin' on up here? We're havin' a grand time downstairs!" One of the Blondes looks up and says, "Yeah, but you've got a driver!"
