In the 1. 95. 0s, this idea stimulated enthusiasm for discovering the genetic molecule. Although the existence of DNA had been known since 1. Schr. At that time DNA was not yet accepted as the carrier of hereditary information, which only was the case after the Hershey. One of the most successful branches of physics at this time was statistical physics, and quantum mechanics, a theory which is also very statistical in its nature. Muller had in his 1.

But DNA as the molecule of heredity became topical only after Oswald Avery's most important bacterial- transformation experiments in 1. Before these experiments, proteins were considered the most likely candidates. Content. He calls this principle .

The ghost-written book that made Popular Science popular., Dover publications, 1944 Old but good. Most importantly, he elaborates the important role mutations play in evolution. He concludes that the carrier of hereditary information has to be both small in size and permanent in time, contradicting the na. This contradiction cannot be resolved by classical physics. In chapter IV, Schr. Even though molecules were known before, their stability could not be explained by classical physics, but is due to the discrete nature of quantum mechanics. Furthermore, mutations are directly linked to quantum leaps. He continues to explain, in chapter V, that true solids, which are also permanent, are crystals. The stability of molecules and crystals is due to the same principles and a molecule might be called . He calls this an aperiodic crystal. Its aperiodic nature allows it to encode an almost infinite number of possibilities with a small number of atoms. He finally compares this picture with the known facts and finds it in accordance with them. In chapter VI Schr. The main principle involved with . But even those are influenced by thermal and frictional forces. The degree to which a system functions mechanically or statistically depends on the temperature. If heated, a clock ceases to function, because it melts. Conversely, if the temperature approaches absolute zero, any system behaves more and more mechanically. Some systems approach this mechanical behaviour rather fast with room temperature already being practically equivalent to absolute zero. Schr. He believes he must reconcile two premises: (1) the body fully obeys the laws of quantum mechanics, where quantum indeterminacy plays no important role except to increase randomness at the quantum scale; and (2) there is . He also rejects the idea that there are multiple immortal souls that can exist without the body because he believes that consciousness is nevertheless highly dependent on the body. In the final paragraph, he points out that what is meant by . Since life approaches and maintains a highly ordered state, some argue that this seems to violate the aforementioned Second Law implying that there is a paradox. However, since the biosphere is not an isolated system, there is no paradox. The increase of order inside an organism is more than paid for by an increase in disorder outside this organism by the loss of heat into the environment. By this mechanism, the Second Law is obeyed, and life maintains a highly ordered state, which it sustains by causing a net increase in disorder in the Universe.
