Quotations for Today
(About conveyance of cholera through drinking water) "...there is often a way open for it to extend itself more widely, and to reach the well-to-do classes of the community; I allude to the mixture of cholera evacuations with the water used for drinking and culinary purposes, either by permeating the ground, and getting into wells, or by running along channels and sewers into the rivers from which entire towns are sometimes supplied with water." - Dr. John Snow (born 15 Mar 1813) - writing in 1849,  five years before his dramatic proof of this transmission mode when, on 8 Sep 1854, he removed the Broad Street water pump handle and halted a severe outbreak of cholera in London.

"I do not believe that the present flowering of science is due in the least to a real appreciation of the beauty and intellectual discipline of the subject. It is due simply to the fact that power, wealth and prestige can only be obtained by the correct application of science." - Sir Derek H.R. Barton, British Nobel prize-winning chemist (born 9 Sep 1918)

"Isolated facts and experiments have in themselves no value, however great their number may be. They only become valuable in a theoretical or practical point of view when they make us acquainted with the law of a series of uniformly recurring phenomena, or, it may be, only give a negative result showing an incompleteness in our knowledge of such a law, till then held to be perfect." - Hermann von Helmholtz, German physicist and physiologist (died 8 Sep 1894)
