Clinton Joseph Davisson

Born 22 Oct 1881; died 1 Feb 1958 at age 76. American physicist who shared the Nobel Prize for Physics in 1937 (with Englishman George P. Thomson) for discovering that electrons can be diffracted like light waves, thus verifying the thesis of Louis de Broglie that electrons behave both as waves and as particles. Davisson studied the effect of electron bombardment on surfaces, and observed (1925) the angle of reflection could depend on crystal orientation. Following Louis de Broglie's theory of the wave nature of particles, he realized that his results could be due to diffraction of electrons by the pattern of atoms on the crystal surface. Davisson worked with Lester Germer in an experiment in which electrons bouncing off a nickel surface produced wave patterns similar to those formed by light reflected from a diffraction grating, and supporting de Broglie's electron wavelength = (h/p). This discovery has been applied to the study of nuclear, atomic, and molecular structure. Davisson helped develop the electron microscope which uses the wave nature of electrons to view details smaller than the wavelength of visible light.

Three women: one engaged, one...

Three women: one engaged, one married and one a mistress, are chatting about their relationships and decided they needed to spice up their love lives. All three agreed to wear black leather bras, stiletto heels and a mask over their eyes that evening with their respective lovers.
After a few days they meet up for lunch and compared notes.
The engaged woman: "The other night when my boyfriend came over he found me with a black leather bodice, tall stilettos and a mask. He saw me and said, 'You are the woman of my life. I love you.' Then we made love all night long."
The mistress: "Me too! The other night I met my lover at his office and I was wearing the leather bodice, heels, mask over my eyes and a raincoat. When I opened the raincoat he didn't say a word, but we had wild sex all night."
The married woman: "I sent the kids to stay at my mother's house for the night when my husband came home I was wearing the leather bodice, black stockings, stilettos and a mask over my eyes. As soon as he came in the door and saw me he said, 'What's for dinner, Batman?'"
