An Irishman, an Italian, and a...

An Irishman, an Italian, and a Polish guy are in a bar. They are having a good time and all agree that the bar is a nice place.
Then the Irishman says, "Aye, this is a nice bar, but where I come from, back in Dublin, there's a better one. At McDougal's, you buy a drink, you buy another drink, and McDougal himself will buy your third drink!" The others agree that sounds like a nice place.
Then the Italian says, "Yeah, that's a nice bar, but where I come from, there's a better one. Over in Brooklyn, there's this place, Vinny's. At Vinny's, you buy a drink, Vinny buys you a drink. You buy another drink, Vinny buys you another drink." Everyone agrees that sounds like a great bar.
Then the Polish guy says, "You think that's great? Where I come from, there's this place called Warshowski's. At Warshowski's, they buy you your first drink, they buy you your second drink, they buy you your third drink, and then, they take you in the back and get you laid!"
"Wow!" say the other two. "That's fantastic! Did that actually happen to you?"
"No," replies the Polish guy, "but it happened to my sister!"

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.
