In Love

The pretty teacher was concerned with one of her eleven-year-old students. Taking him aside after class one day, she asked, "Little Johnny, why has your school work been so poor lately?"
"I'm in love," the boy replied.
Holding back an urge to smile, she asked, "With whom?"
"With YOU!" he said.
"But Johnny," she said gently, "don't you see how silly that is? It's true that I would like a husband of my own someday. But I don't want a child."
"Oh, don't worry," the boy said reassuringly, "I'll use a rubber!"

Joseph Black

Died 6 Dec 1799 at age 71 (born 16 Apr 1728). Scottish chemist and physicist who experimented with "fixed air" (carbon dioxide), discovered bicarbonates and identified latent heat. He lectured in chemistry, anatomy at the University of Glasgow, while also a physician. From heated magnesia alba (magnesium carbonate), Black collected a gas, carbon dioxide, different from common air. He published Experiments Upon Magnesia Alba, Quicklime, and Some Other Alcaline Substances (1756). Carbon dioxide was also released by fermentation, respiration, and burning charcoal so he assumed it was in the atmosphere. He also observed that ice melts without change of temperature, due to heat that becomes "hidden" - latent heat - and determined "specific heat" for heated of materials.[DSB gives date of death 6 Dec 1799. EB gives 10 Nov 1799.]
