Al Torat HaYachasiyut HaPeratit VehaKelalit (Harza’ah Popularit). Translated into Hebrew from the original German by Yaakov Greenberg.

First Hebrew translation of Einstein’s revolutionary text: Über die spezielle und die allgemeine Relativitätstheorie (Gemeinverständlich) [”The Special and the General Theory of Relativity.”] This Hebrew edition was particularly dear to Einstein as he noted in the foreword: “The appearance of this, my book, in the language of our forefathers fills my heart with special joy. It is a sign of the transformation that has occurred in this language [of ours]. It is not enough to focus at present on its use in this area alone, namely that of expressing the central issues of our people to our own people, but more appropriately to absorb within it all that humanity finds of value. It [Hebrew] serves as an important factor in our aspiration for an independent cultural existence.”
