A rather awkward freshman finally got up the nerve to ask a pretty junior for a dance at the homecoming. She gave him the once-over and said, "Sorry, I won't dance with a child."
"Please forgive me," responded the underclassman. "I didn't realize you were pregnant."
Pierre WeissDied 24 Oct 1940 at age 75 (born 25 Mar 1865).French physicist who investigated magnetism and determined the Weiss magneton unit of magnetic moment. Weiss's chief work was on ferromagnetism. Hypothesizing a molecular magnetic field acting on individual atomic magnetic moments, he was able to construct mathematical descriptions of ferromagnetic behaviour, including an explanation of such magnetocaloric phenomena as the Curie point. His theory succeeded also in predicting a discontinuity in the specific heat of a ferromagnetic substance at the Curie point and suggested that spontaneous magnetization could occur in such materials; the latter phenomenon was later found to occur in very small regions known as Weiss domains. His major published work was Le magnetisme ( 1926). |
