When my 14-year-old son, Patrick, stepped up to the plate during a Colt League baseball game, the young announcer declared, "Now batting, the right fielder, number 12, Pathogen!"
After some confusion in the stands, the announcer came back on over the loudspeaker. "Sorry folks, that's PAT Hogan!"
Étienne-François GeoffroyDied 6 Jan 1731 at age 58 (born 13 Feb 1672).French chemist, who was the first to recognize the relative fixed affinities of reagents for one another. He composed tables (1718) listing the relative affinities of different reagents for particular substances, showing how one acid displaces another acid of weaker affinity for a specific base in the salt of that base. (These tables stood for most of the 18th century, until Claude-Louis Berthollet demonstrated that reactions instead depend upon the initial relative quantities of the reactants and physical conditions during the reaction.) Geoffroy considered the quest for the philosopher's stone (a substance capable of transforming base metals into gold) a delusion, but he believed that iron could be formed during the combustion of vegetable matter. |
