The developments of the intervening years have emphasized this key position. We had then just shown with x-rays that radiation has the combined characteristics of waves and particles. I t has since been found that electrons, protons and atoms likewise have these dual properties, thus forming the experimental basis of the principle of uncertainty, with all its fundamental implications. In the diffraction of x-rays we have found direct methods of observing the average positions and motions of electrons in atoms and of the thermal motions of atoms in crystals and molecules, establishing the correctness of the main predictions by the new quantum mechanics.
