Living organisms in order to orient themselves in the environment measure an enormous number of parameters and therefore biophysics cannot use only the laws of the ordinary physics but must take into account the influence on the phenomena studied of the measurement and the computer process in actual physical or biophysical devices engaged in predicting the future. Science allowing for the influence of the computer process-realistic or informational (r.i.) physics-has different "laws" for different times, distances and the number of measured and predicted parameters. R.i. physics deals with non-reproducible events and considers only such time intervals and distances for which prediction may be made on the basis of the former measurements and calculations (by laws with optimal complexity). It is assumed that the live cell obeys the laws close to those optimal (limiting) laws of r.i. physics. Physics and quantum mechanics are regarded as the limiting case of r.i. physics in which the distance and times used are made sufficiently long and the number of simultaneously measured independent parameters small so that the influence of the computer device becomes negligibly small. The molecular computer machine of the cell (m.c.) [1] cannot calculate the interaction of a large number of different molecules by using the equations of quantum mechanics since the expenditure of the "price of action" would be too great and both the m.c. and the world surrounding it would change.
