Eo animo quidque debetur quo datur, nec quantum sit sed a quali profectum voluntate perpenditur.

Our feeling about every obligation depends in each case upon the spirit in which the benefit is conferred; we weigh not the bulk of the gift, but the quality of the good-will which prompted it.

Letter LXXXI: On benefits, line 6Seneca the Younger
» Seneca the Younger - all quotes »
It seems clear that the present quantum mechanics is not in its final form. Some further changes will be needed, just about as drastic as the changes made in passing from Bohr's orbit theory to quantum mechanics. Some day a new quantum mechanics, a relativistic one, will be discovered, in which we will not have these infinities occurring at all. It might very well be that the new quantum mechanics will have determinism in the way that Einstein wanted.
Paul Dirac
Does life in some way make use of the potentiality for vast quantum superpositions, as would be required for serious quantum computation? How important are the quantum aspects of DNA molecules? Are cellular microtubules performing some essential quantum roles? Are the subtleties of quantum field theory important to biology? Shall we gain needed insights from the study of quantum toy models? Do we really need to move forward to radical new theories of physical reality, as I myself believe, before the more subtle issues of biology — most importantly conscious mentality — can be understood in physical terms? How relevant, indeed, is our present lack of understanding of physics at the quantum/classical boundary? Or is consciousness really “no big deal,” as has sometimes been expressed?
It would be too optimistic to expect to find definitive answers to all these questions, at our present state of knowledge, but there is much scope for healthy debate...Roger Penrose
If quantum communication and quantum computation are to flourish, a new information theory will have to be developed.
