Charles Barkla

Died 23 Oct 1944 at age 67 (born 7 Jun 1877).Charles Glover Barkla was an English physicist who was awarded the Nobel Prize for Physics in 1917 for his work on X-ray scattering. This technique is applied to the investigation of atomic structures, by studying how X-rays passing through a material and are deflected by the atomic electrons. In 1903, he showed that the scattering of x-rays by gases depends on the molecular weight of the gas. His experiments on the polarization of x-rays (1904) and the direction of scattering of a beam of x-rays (1907) showed X-rays to be electromagnetic radiation like light (whereas, at the time, William Henry Bragg who held that X-rays were particles.) Barkla further discovered that each element has its own characteristic x-ray spectrum.«

An old indian, Charlie Two Shi...

An old indian, Charlie Two Shirts, came rowing onto the dock on a lake. He tied his boat up and unloaded his fishing box that was full of fish.
The Game warden was standing there and said: "Charlie there aren't that many fish in this lake. How did you get those?"
Charlie said: "Oh it is an old Indian method. Come with me and I show you!"
The Game Warden got in the boat and Charlie rowed out to a spot. He opened his tackle box and got out a weighted stick of dynamite, lit the fuse and tossed it overboard. Moments later there was a muffled explosion from below and several fish came floating up.
The Game Warden said: "Charlie it's illegal to use dynamite for fishing. I can arrest your for that!"
Charlie reached into his tackle box again and pulled out another stick of dynamite. He lit the fuse and handed it to the Game Warden and said: "Are you gonna fish...or talk?"
