| Quotations for Today | |
| "I would hazard a guess that we have found fossilized human remains of at least a thousand different specimens in South and East Africa, more or less complete at that. I think this is where the prelude to human history was primarily played out." - Richard Leakey (born 19 Dec 1944) "The most important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplemented in consequence of new discoveries is exceedingly remote ... our future discoveries must be looked for in the sixth decimal place." - Albert Michelson, German-American physicist (born 19 Dec 1852) "We all felt the majesty of the body. As we saw the artificial heart beat the feeling was not aren't we great, but aren't we small." - Dr William C. DeVries, American heart surgeon who made the first human implant of a permanent artificial heart (born 19 Dec 1943) | |
