A Texan was taking a taxi tour...

A Texan was taking a taxi tour of London and was in a hurry. As they went by the Tower of London the cab driver explained what it was and that construction of it started in 1346 and was completed in 1412.
The Texan replied, "Shoot, a little ol' tower like that? In Houston we'd have that thing up in two weeks!"
Next they passed the House of Parliament - started in 1544 and completed in 1618.
"Well boy, we put up a bigger one than that in Dallas and it only took a year!"
As they passed Westminster Abbey the cab driver was silent.
"Whoah! What's that over there?" asked the Texan.
The driver replied, "I don't know, it wasn't there yesterday."

Cryosurgery

In 1960, Dr Irving Cooper received a Christmas gift that inspired his invention of the first cryosurgery device (to freeze tissue). The gift was a wine-bottle opener which lifted the cork by injecting carbon dioxide gas into the bottle. He observed the gas was very cold when released and he could direct small squirts from it to freeze tiny areas on the palm of his hand and watch them thaw. He also observed the freezing effect was very localized and isolated from the surrounding tissue. From this inspiration, he developed a technique of brain surgery in which he used liquid nitrogen flowing in a thin tube first to deaden, and then freeze, tremor-causing brain cells or tumours. The invention created a new field of surgery with applications for other areas of the body as well.
