or bacteria in order to determine whether there is a large amount of a certain substance‚ and to determine the size of different particles. One main use for light in virtual drug screening is high throughput screening‚ which allows the researcher to do multiple numbers of tests on substances and quickly identify them. For example‚ a researcher can use light scattering to screen for ligands by measuring the amount of light scattered. The scattered light can be used to determine if there is an aggregation

Lord Rayleigh and Sir William Ramsey succeeded in proving that there must exist a previously unknown gas in the atmosphere. They subsequently worked in their separate laboratories on this problem but communicated the results of their labors almost daily. At the meeting of the British Association in August 1894‚ they announced the discovery of Argon. They found the gas by isolating a small sample of the nonreactive portion of atmospheric nitrogen; once all the oxygen and nitrogen were removed from
