### Jim was a just out of boot cam...

Jim was a just out of boot camp, and was on his first ship. About two hours out of port, he began to get a bit ill from the motion of the ship. He approached an ensign, also just out of training and on his first cruise.
He saluted and said, "Excuse me sir, I am feeling seasick, and I wondered if I may have permission to go downstairs to the dispensary."
The ensign returned his salute and replied, "Sailor, you are in the Navy now. You don't go downstairs, you go below! There is no dispensary on this ship, there is sickbay. Not only that, that is not the floor, it is a deck; that is not the ceiling, it is the overhead; that is not a pillar, it is a stanchion; that is not a water fountain, it is a scuttlebutt. If I ever hear you using civilian words instead of Naval jargon, I will throw you out of that little round window over there."

### Germain Henri Hess

Born 8 Aug 1802; died 13 Dec 1850 at age 48.Swiss-Russian chemist whose studies of heat in chemical reactions formed the foundation of thermochemistry. He formulated an empirical law, Hess's law of constant heat summation (1840), which states that the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps. It is explained by thermodynamic theory, which holds that enthalpy is a state function. Chemists have made great use of the law of Hess in establishing the heats of formation of compounds which are not easily formed from their constituent elements. His early investigations concerned minerals and the natural gas found near Baku, and he also discovered the oxidation of sugars to yield saccharic acid.DSB gives dates as 8 Aug 1802 - 13 Dec 1850. EB gives 7 Aug 1802 - 30 Nov 1850.]
