Abstract
THE latest developments of physical theories point not only to the possibility of a complete change in our conception of the nature of matter, but also in our views of causality and natural law. They are no longer purely mathematical and experimental. Speculations are being made in regions formerly regarded as metaphysical and outside the limitations of human knowledge. No one can say where these speculations will lead us. Recent theories, however, are becoming more acceptable to the average physicist. Electrons and protons appearing as energy centres in so-called material waves remind us of the vortex rings which were much studied fifty years ago.
