Abstract

HERE are six accounts of the Relativity theory designed for the general reader. The first four hail from Messrs. Methuen, who had the enterprise to secure an English translation of Einstein's own popular exposition, and have also recently published a translation of Weyl's “Space, Time and Matter.” The fifth is published in Johannesburg by the Council of Education, Witwatersrand. The last comes from the pen of an eminent German professor of physics.
