Scientific method done by the person who made the prediction, and the characterization is based on experiments done by someone else. Published results of experiments can also serve as a hypothesis predicting their own reproducibility. After considerable fruitless experimentation, being discouraged by their superior from continuing, and numerous false starts, Watson and Crick were able to infer the essential structure of DNA by concrete modeling of the physical shapes of the nucleotides which comprise it. They were guided by the bond lengths which had been deduced by Linus Pauling and by Rosalind Franklin's X-ray diffraction images. .."DNA Example" Science is a social
X-ray crystallography polymethylcyanoacrylaon of Boin crystal parameters. Heating or burning of bones causes recognizeable changes in the bone mineral that can be detected using X-ray diffraction (XRD) techniques. During the first 15 minutes of heating at 500 °C or above, the bone crstals began to change. At higher temperatures, thickness and shape of crystals of bones appear stabilized, but when the samples were heated at lower temperature or for shorter period, XRD traces showed extreme changes in crystal parameters. X-ray diffraction has been demonstrated as a method for investigating the complex structure of integrated circuits. X-ray crystallography X-ray crystallography is a technique
