Quotations for Today

"Over the last century, physicists have used light quanta electrons, alpha particles, X-rays, gamma-rays, protons, neutrons and exotic sub-nuclear particles for this purpose (scattering experiments). Much important information about the target atoms or nuclei or their assemblage has been obtained in this way. In witness of this importance one can point to the unusual concentration of scattering enthusiasts among earlier Nobel Laureate physicists. One could say that physicists just love to perform or interpret scattering experiments."
- Clifford G. Shull, American Nobel prize-winning physicist (born 23 Sep 1915) Quotes Icon
"No, our science is no illusion. But an illusion it would be to suppose that what science cannot give us we can get elsewhere."
Austrian father of psychoanalysis in the quiz below (died 23 Sep 1939) Quotes Icon
"Organic chemistry nowadays almost drives one mad. To me it appears like a primeval tropical forest full of the most remarkable things, a dreadful, endless jungle into which one dare not enter, for there seems no way out."
- Friedrich Wohler, German chemist (died 23 Sep 1882) Quotes Icon

He sent a narrow beam of light between rotating gear teeth  to a mirror 8 km/5 mi away. He observed whether on its return the beam was then blocked by a tooth. From the rotational speed of the wheel, and the mirror's distance, he directly measured the speed of light.
