Science Quiz  1. When light is scattered from an atom or molecule, most photons are elastically scattered (Rayleigh scattering), such that the scattered photons have the same energy (frequency) and wavelength as the incident photons. However, a small fraction of the scattered light (approximately 1 in 10 million photons) is scattered by an excitation, with the scattered photons having a frequency different from, and usually lower than, the frequency of the incident photons. Which phenomenon are we talking about? Answer: Raman Effect 2. Who was the first scientist to win Nobel prize twice? Answer: Madam Marrie Currie 3. Formally designated as the MED, it refers specifically to the period of the project from 1939–1946 under the control of the U.S. Army Corps of Engineers, under the administration of General Leslie R. Groves. The scientific research was directed by American physicist J. Robert Oppenheimer. The highest academic qualification required for the common labour of the project was that they had to be illiterate. Which famous project is being talked about? Answer: The Manhattan Project for developing the first atom bomb 4. For what contribution did Albert Einstein receive the Nobel Prize in 1929? Answer: The Photoelectric law (not theory of relativity) 5. He was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian and one of the most influential men in human history. His Philosophie Naturalis Principia Mathematica, published in 1687, is considered to be the most influential book in the history of science, laying the groundwork for most of classical mechanics. Which great man is being referred to? Answer: Sir Issac … [Read more...]
