Four Surgeons

Four surgeons were sitting around discussing who they like to operate on.
The first surgeon said, "I like operating on librarians. When you open them up everything is in alphabetical order".
The second surgeon said, "I like operating on accountants. When you open them up everything is in numerical order".
The third surgeon said, "I like operating on electricians. When you open them up everything is color coded.
The fourth surgeon said, "I like operating on lawyers".
The other three surgeons looked at each other in disbelief. One of them asked why.
The fourth surgeon replied, "Because they are heartless, gutless, spineless, and their ass and head are interchangeable".

Cosmic rays

In 1925, the confirmation of highly-penetrating radiation from “finite space” was announced by Robert A. Millikan, calling them “cosmic rays.” He spoke to the National Academy of Sciences at Madison, Wisconsin. Earlier tests with high-altitude balloons, or atop mountains, remained inconclusive as to extra-terrestrial origin. The rays, he thought then, could be of local origin from radioactive materials. However, in 1925, measurements he made up to 27-m below Muir Lake (altitude 3540-m) and Lake Arrowhead (alt. 1530-m) showed rays reached given depths in each by comparable amounts. Thus the atmosphere difference of 2-km did not originate the rays, they had 18 times the penetrating power of any known gamma rays, and possibly were the “birth cries” of infant atoms from fusion or electron capture.«[This work by Millikan on cosmic rays became known to the public in newspaper articles on 11 Nov 1925. He was already a noted scientist, having received a Nobel Prize in Physics in 1923. Atmospheric radiation had been noted before by others since 1901.]
