Abstract
THE new ‘Unified Field-Theory’ of Einstein is contained in two papers amounting altogether to eleven pages in the Berlin Sitzungsberichte, 17, 1928, and 1, 1929. There is an intermediate paper which does not concern us, since it follows a line of development now abandoned. For the present, at any rate, a non-mathematical explanation is out of the question, and in any case would miss the main purpose of the theory, which is to weld a number of laws into a mathematical expression of formal simplicity. We are chiefly interested in how it compares, both as to methods and results, with the existing field-theories which have had some measure of success.
