The sailor came home from a secret two year mission only to find his wife with a newborn baby. Furious, he was determined to track down the father to extract revenge.
"Was it my friend Sam?" he demanded.
"No!" his weeping wife replied.
"Was it my friend Jim then?" he asked.
"NO !!!" she said even more upset.
"Well which one of my no-good friends did this then?" he asked.
"Don't you think I have any friends of my own?" she snapped.

Jean Charles Marignac

Died 15 Apr 1894 at age 76 (born 24 Apr 1817).Swiss chemist whose life work consisted of making many precise determinations of atomic weights suggested the possibility of isotopes and the packing fraction of nuclei. He began a study of the rare-earth elements in 1840, when barely 23 years old. In 1878, he heated until it decomposed some erbium nitrate obtained from gadolinite. Extracting the product with water he obtained two oxides: a red one he named erbia and a colourless one he named ytterbia. Thus he discovered ytterbium, and later was a codiscover of gadolinium (1880). By separating tantalic and columbic acids, he also proved that tantalum and colubium (niobium) were not identical. The last 10 years of his life he lay prostrate, suffering intensely from heart disease.
