"Thanks for the harmonica you gave me for Christmas," little Joshua said to his uncle the first time he saw him after the holidays. "It's the best present I ever got."
"That's great," said his uncle. "Do you know how to play it?"
"Oh, I don't play it," the little fellow said. "My mom gives me a dollar a day not to play it during the day and my dad gives me five dollars a week not to play it at night.
Viktor MeyerDied 8 Aug 1897 at age 48 (born 8 Sep 1848).German organic chemist who contributed greatly to knowledge of both organic and inorganic chemistry and invented an apparatus for determining vapour densities (and hence molecular weights), now named after him. In 1871, Meyer experimentally proved Avogadro's hypothesis by measuring the vapour densities of volatile substances (molecular weight, or relative molecular mass, is twice the vapour density). He went on to determine the vapour densities of inorganic substances at high temperatures. From benzene obtained from petroleum, Meyer in 1883 isolated thiophene, a heterocyclic compound containing sulphur, which much later was to become an important component of various synthetic drugs. |
