Eigen, Manfred. (1927-). A German physicist who won the Nobel Prize for chemistry in 1967. His research concerned the rate of hydrogen-ion formation through disassociation of water. He also was concerned with enzyme control. He received his degree at the University of Gottingen.

Why this is so cannot be explained. Egually inexplicable is the trend towards the more-complex structures and systems observed in evolution. Even if we conclude from this that life in its beginning had to be relatively simple, it was still not primitive. Manfred Eigen (Nobel Prize 1967) in particular pointed out that one property of matter must have played a decisive role the ability to self-assemble. From there he postulated that "Life comes into existence when the conditions for it are suitable". Could a different life have come into existence had the conditions been different We don t know. Instead, we know a lot about life that we can observe and investigate. 

The critical discussion of some aspects of Eigen s theories and hypotheses by no means diminishes the great merits which Manfred Eigen has gained in more than 30 years of work in this area of science. His experimental and theoretical contributions to the question of the evolution of genetic information are of decisive importance, even if corrections of his theories may be necessary from time to time. 

How can negative fluctuations in entropy production occur or be triggered As Manfred Eigen shows in his evolution theory, fluctuations in entropy production can be caused by the coming into being of a self-replicating molecular species which is capable of selection. Autocatalytically active mutants can also have the same effect. Looked at this way, the phenomenon of evolution consists of a continuous series of instabilities, i.e., collapses of stationary states. 

Manfred Eigen Germany study of very fast chemical reactions... 

During the past year, in association with Manfred Eigen in Gottingen, Germany, I examined a number of substitution reactions of nickel to see if there was indeed a direct relationship between the charge of a complex and its rate of water substitution. The temperature jump method was used to measure the rate of substitution of NH3 for water with various complexes.
