### Three old men

Three old men are talking about their aches, pains and bodily dysfunctions.

One 75-year-old man says: "I have this problem. I wake up every morning at 7 a.m. and it takes me 20 minutes to pee."

An 80-year-old man says: "My case is worse. I get up at 8 a.m. and I sit there and grunt and groan for half an hour before I finally have a bowel movement."

The 90-year-old man says: "Not me. At 7 a.m. I pee like a horse and at 8 a.m. I crap like a cow."

"So what's your problem?" asked the others.

"I don't wake up until 9:00."

## Joseph LoschmidtDied 8 Jul 1895 at age 74 (born 15 May 1821). Johann Joseph Loschmidt was an Austrian chemist and physicist who was thefirsttopropose(1861) some kind of cyclic structure for benzene and many aromatic hydrocarbons. (Four years later, Kekulé devised the correct ring structure, for which his name is remembered while Loschmidt's contribution is overlooked.) He deduced the size of air molecules to be around one nanometer, with two approaches: relating the size of gas molecules to the distance travelled between collisions, and considering the packed volume of molecules in a cold liquid. Completing Avogadro's insight that all gases have the same number of molecules in a given volume, Loschmidt measured Avogadro's constant to be 6.03 x 1023 molecules in one mole of a gas (1865).« |
