Quotations for Today
	Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it is the only thing that ever has. - Margaret Mead, American anthropologist (born 16 Dec 1901).
	Almost all the world is natural chemicals, so it really makes you re-think everything. A cup of coffee is filled with chemicals. They've identified a thousand chemicals in a cup of coffee. But we only found 22 that have been tested in animal cancer tests out of this thousand. And of those, 17 are carcinogens. There are ten milligrams of known carcinogens in a cup of coffee and thats more carcinogens than youre likely to get from pesticide residues for a year! - Bruce Nathan Ames, American biochemist and molecular biologist (born 16 Dec 1929).
	Compounds formed by chemical attraction, possess new properties different from those of their component parts... chemists have long believed that the contrary took place in their combination. They thought, in fact, that the compounds possessed properties intermediate between those of their component parts; so that two bodies, very coloured, very sapid, or insapid, soluble or insoluble, fusible or infusible, fixed or volatile, assumed in chemical combination, a shade or colour, or taste, solubility or volatility, intermediate between, and in some sort composed of, the same properties which were considered in their principles. This is an illusion or error which modern chemistry is highly interested to overthrow. - Comte de Antoine Francois Fourcroy, French chemist (died 16 Dec 1809).
