WAIT ’TILL NEXT YEAR by William Goldman and Mike Lupica (August 10‚ 2005) At least twice a day‚ a high school or college student sends me an e-mail asking for advice -- they want to write about sports some day‚ they don’t know how to go about it‚ and they’re wondering if I can help. And I never know what to write back. How can you answer a question like‚ "I want to write a sports column‚ tell me what to do?" Last weekend‚ I thought of an answer. Just a quick back story: I probably own

X-ray diffraction has perhaps been one of the most critical and exigent discoveries of the 20th century. Early X-ray diffraction images for tobacco mosaic virus had been collected before World War II. By 1954‚ Watson had discovered from his X-ray diffraction images that the tobacco mosaic virus had a helical structure‚ and was able to apply this to his famous DNA structure research. It is so valued because it allows the structure of a crystalline material can be determined‚ based on the diffraction

In a world where books are outlawed and knowledge is scoffed‚ separation from true feelings means true happiness. Or does it? Ray Bradbury’s book‚ Fahrenheit 451‚ illustrates exactly what the world would be if people were separated so completely from their feelings that they were unable to comprehend the true meaning and feeling of real satisfaction. Although Fahrenheit 451 and our society today are distinctly different‚ they also have some startling similarities. Why are people separated from their

Principles of X-ray Diffraction Diffraction effects are observed when electromagnetic radiation impinges on periodic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which correspond in the electromagnetic spectrum with the wavelength of x-rays having photon energies between 3 and 8 keV. Accordingly‚ phenomena like constructive and destructive interference should become observable
