Juston McKinney: Parking Tickets in New York

The first ticket I got in Manhattan I thought was a misprint. Im like, No, this has got to be a mistake. You put a quarter in the meter out there and it runs out, its a $55 fine. Thats a little excessive. Now, I could see it if you parked in a handicapped persons living room, but not for the meter running out. It goes from 25 cents to $55. Thats a 22,000% increase.

Auguste Laurent

Died 23 Apr 1853 at age 45 (born 14 Nov 1807). French chemist who developed organic chemistry as a distinct science. For a while, he assisted Jean Dumas, and extended his work, understanding organic compounds as derivatives of hydrocarbon molecules. In crystallography he was influenced by René-Just Haüy. Laurent recognised that carbon atoms formed bonds based on a pyramid structure. Furthermore, against the opinion of many peers, he rejected the idea held by Jöns Berzelius that even organic molecules were formed from positively and negatively charged entities. Laurent showed (1836) that a supposedly positive-charge hydrogen atom could be replaced by a supposedly negative-charge chlorine atom. He recognised families of organic compounds with characteristic groups. He died in middle age from tuberculosis.«
