About particle and field 507 kB, 47 sek

"The well established view today is rather that everything - anything at all - is at the same time particle and field. Everything has the continuous structure with which we are familiar from the field, as well as the discrete structure with wich we are equally familiar from particles. Expressed in such a general way this proposition has certainly a high degree of truth. For it is supported by innumerable experimental facts."

Erwin Schrödinger, 1952
