Theory of Elementary Particles
Werner Heisenberg · Science · 1955
It is obvious that at the present state of our knowledge it would be hopeless to try to find the correct theory of the elementary particles. On the other hand, one may try to form some kind of picture of how such a future theory of elementary particles will look, because, even if we realize that we know only very few details about the elementary particles, we have already quite a good qualitative picture of them, and we feel that even if the experiments go on for 5 or 10 or even more years, this qualitative picture will scarcely change.
