Josh Sneed: After-Christmas Sale

I was walking back through this mall in January; there was a girl in front of Victorias Secret who stopped me. She was like, Hey, hows it going? I was like, Good, how are you? She goes, Well, Im curious, are you shopping for a wife or girlfriend today? I was like, No, why? She goes, Well, were having this after-Christmas sale, and all our bras are 50% off. And I go, I like when your bras are 100% off.

Vincenzo Galilei

Died 2 Jul 1591 (born 1520). Italian music theorist, lutenist and composer, who as the father of Galileo Galilei, adopted experimentation to prove aspects of acoustics, and may thus have influenced his son, Galileo, away from pure, abstract mathematics and towards making experiments and investigation. Vincenzo's discoveries in acoustics included some of the physics of vibrating strings and columns of air. In particular he was the first to show that the ratio of an interval was proportional to string lengths but varied as the square of the tension applied to the strings and as the cubes of volumes of air. He recognized the superiority of equal tempered tuning and compiled a codex of pieces illustrating the use of all 24 major and minor keys as early as 1584.
