The Blessing – You may have lived this one

'I wouldn't know what to say,' the girl replied.
'Just say what you hear Mommy say,' Joan answered.
The girl thought for a minute, then bowed her head and said, 'Lord, why on earth did I invite all these people to dinner?'

Joseph Louis Gay-Lussac

Died 9 May 1850 at age 71 (born 6 Dec 1778). French chemist best known for his work on gases. In 1805, by exploding together given volumes of hydrogen and oxygen, Gay-Lussac discovered they combined in ratio 2:1 by volume to form water. By 1808, after researches using other gases, he formulated his famous law of combining volumes - that when gases combine their relative volumes bear a simple numerical relation to each other (e.g., 1:1, 2:1) and to their gaseous product (under constant pressure and temperature). He developed techniques of quantitative chemical analysis, confirmed that iodine was an element, discovered cyanogen, improved the process for manufacturing sulphuric acid, prepared potassium and boron (1808). He made two balloon ascents to study the atmosphere.
