Old Man Hot Mama

An old hearing impaired gentleman visited his doctor and he had been warned to be careful as he had a heart murmur.

The doctor was therefore most surprised to see the old fellow out on the town, whooping it up. He got his attention and took him aside. "Don't you remember what I told you the other day?" he inquired.

"Oh, I surely do." the old gent replied, "Best dang advice I ever had. I did just as you said. I got me a hot mama and I'm cheerful"

Macedonio Melloni

Died 11 Aug 1854 at age 56 (born 11 Apr 1798).Italian physicist who was the firstto extensively research infrared radiation. Sir William Frederick Herschel discovered infrared radiation in 1800, but research stalled until the invention of a thermopile in 1830. That instrument was a series of strips of two different metals that produced electric current when one end was heated. Melloni improved the thermopile and used it to detect infrared radiation. In 1846, from an observation point high on Mount Vesuvius, he measured the slight heating effect of moonlight. He showed also that rock salt, being transparent to infrared, made suitable lenses and prisms to demonstrate the reflection, refraction, polarization and interference of infrared in the same manner as visible light.
