| Quotations for Today |
| "The history of acceptance of new theories frequently shows the following steps: At first the new idea is treated as pure nonsense, not worth looking at. Then comes a time when a multitude of contradictory objections are raised, such as: the new theory is too fancy, or merely a new terminology; it is not fruitful, or simply wrong. Finally a state is reached when everyone seems to claim that he had always followed this theory. This usually marks the last state before general acceptance." (1943) - Kurt Lewin, German-born American social psychologist (born 9 Sep 1890) "Science attempts to find logic and simplicity in nature. Mathematics attempts to establish order and simplicity in human thought." (1980) - Edward Teller, Hungarian-born American physicist (died 9 Sep 2003) "The most fundamental difference between compounds of low molecular weight and macromolecular compounds resides in the fact that the latter may exhibit properties that cannot be deduced from a close examination of the low molecular weight materials. Not very difference structures can be obtained from a few building blocks; but if 10,000 or 100,000 blocks are at hand, the most varied structures become possible, such as houses or halls, whose special structure cannot be predicted from the constructions that are possible with only a few building blocks... Thus a chromosome can be viewed as a material whose macromolecules possess a well-defined arrangement, like a living room in which each piece of furniture has its place." - Hermann Staudinger, German Nobel prize-winning chemist who discovered the structure of polymers as long-chain molecules (died 9 Sep 1965) |
