Albert Einstein, orthodox Jew of German birth and ardent Zionist, is the most discussed figure in intellectual circles in the world today. It is not as a Jew nor as a Zionist, however, that we find him so much in the limelight of public opinion, although as such he is a distinguished figure and has only recently toured Europe and America in the interest of the Zionist movement. What has lately made the name of Einstein a byword upon the lips of scientists, philosophers and the multitudes of more common mortals is his revolutionary treatment of time, space and gravitation which materially affects various branches of accepted science and thereby threatens to throw certain portions of our school books and other scholarly works into the discard.
