Boss (to the new employee): We are very keen on cleanliness. Did you wipe your feet on the mat as you came in?
New employee: Yes, sir.
Boss: We are also keen on truthfulness. There is no mat.
Charles BarklaDied 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.« |
