One lovely morning, Ben and Thomas were out golfing. Ben slices his ball deep into a wooded ravine. He grabs his 8-iron and proceeds down the embankment into the ravine in search of his ball. Ben searches diligently through the thick underbrush and suddenly he spots something shiny. As he gets closer, he realizes that the shiny object is in fact an 8-iron in the hands of a skeleton lying near an old golf ball.
Ben excitedly calls out to his golfing partner: "Hey Thomas, come here, I got big trouble down here."
Thomas comes running over to the edge of the ravine and calls out, "What's the matter Ben?"
Ben shouts back in a nervous voice, "Throw me my 7-iron! Looks like you can't get out of here with an 8-iron."

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.«
