Well, the problem is to know the initial state x. And although in theory we could write a more or less complete set of equations (say classical, nonrelativistic Schroedinger equations for all the protons, neutrons and electrons forming molecules of the virus, the bacterium and some of the...

Mathematics and Biology - on various levels The relationships may be found on various levels. The environment is extremely complex - we can neither know nor even hope to know all the details of microscopic structure of the cell, all the chemical compounds moving within it and interacting...

Neurons There is actually quite a lot of material available on the WEB. There are also *commercial* companies doing what you plan, not just research institutions. For reading material references see for example: T. D. Albright, T. M. Jessell, E. R. Kandel, and M. I. Posne. Neural Science:A...

Software packages R - for statistical analysis and graphing, very large, but maybe somewhat difficult. http://www.r-project.org/ Gnuplot - already mentioned. Graph oriented, with some computational capacities http://www.gnuplot.info/ GLE - graphics layout engine, allows much more than graphs...

As for equilibrium, there is the famous Red Queen hypothesis: you must run as fast as you can just to stay in place. The equilibrium is very dynamical. Remember that the most of the environment we talk about is other organisms: competitors and cooperators from one's own species, organisms we eat...

Perhaps some literature would help AFAIK, there is no definitive answer to this question. But for those who do want more than the limited space of the discussion forums, perhaps some links to current, accessible literature would help? L. E. Orgel...

In most cases it is the random mutation - directed selection process. But... Imagine that the selection is not between genes that decide the colour of the stripes but mutations and selection of genes controlling the rate of - controlling and repair of mutations. Or the meiosis process. In...

Assuming that the experiment is good (it looks nice, both setup and results) then the possible candidates to question are counterfactual definiteness and absence of actions into the past. Especially the latter - as I think a lot remains to be understood with respect to time in QM.

This is strict Copenhagen interpretation. A lot of people accept it (I don't). But my initial question remains valid even in this interpretation. Let me rephrase it as follows: is it possible to measure, in any way, the difference in the state of the atom after emitting the photon, close to the...

Whether the transition is in wavefunction picture or in abstract Hilbert space, the consequences should be the same. Or we would get different QM predictions depending on what representation we use. This would spell trouble for QM... But even in Hilbert space, abstracting from any physical...

Thanks. I'll go through Gisin's paper. I agree that the state of the matter seems to be somewhat undecided. This is why I asked... If you are interested there are more papers that touch the subject, for example: Hegerfeldt, G. C. Instantaneous Spreading and Einstein Causality in Quantum...

A recent preprint on Time in Quantum Theory ( http://www.rzuser.uni-heidelberg.de/~as3/TimeInQT.pdf ) by Dieter H Zeh has brought my attention to the question of the `speed of quantum changes'. While the classical discussions of nonlocality in Quantum Mechanics (QM) and consequences of Bell's...
