A man took his Rottweiler to the vet and said "My dog's cross-eyed, is there anything you can do for him?"
"Well," said the vet, "lets have a look at him." So he picks the dog up and has a good look at its eyes.
"Hmm," says the vet, "I'm going to have to put him down"
"Just because he's cross-eyed?" says the man.
"No, because he's heavy," says the vet.
Charles BarklaBorn 7 Jun 1877; died 23 Oct 1944 at age 67.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.« |
