I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.
Werner HeisenbergThe violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving; and that this motion has caused the feeling that the ground would be cut from science
Werner HeisenbergThe basic idea is to shove all fundamental difficulties onto the neutron and to do quantum mechanics in the nucleus.
Werner HeisenbergNatural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves
Werner HeisenbergIf nature leads us to mathematical forms of great simplicity and beauty - by forms I am referring to coherent systems of hypothesis, axioms, etc. - to forms that no one has previously encountered, we cannot help thinking that they are "true," that they reveal a genuine feature of nature... You must have felt this too: The almost frightening simplicity and wholeness of relationships which nature suddenly spreads out before us and for which none of us was in the least prepared.
