| Quotations for Today | |
| "If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search... I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor." - Nikola Tesla (Died 7 Jan 1943) "I became aware of the spectacular developments made in Cambridge in the 1950s and early 1960s in Molecular Biology through a series of programmes on BBC television given by John Kendrew, and published in 1966 under the title 'The Thread of Life'. These programmes made a lasting impression on me, and made me want to know more about the subject." - John E. Walker, British Nobel prize-winning chemist (born 7 Jan 1941) "I said I liked being half-educated; you were so much more surprised at everything when you were ignorant." - Gerald Durrell, British conservation biologist and prolific author (born 7 Jan 1925) | |
