Yisrael Uryhas developed a unique reputation in both Torah and science. He received his PhD in Applied Physics from the California Institute of Technology and partnered with two colleagues to found Ortel Corporation, a leader in the field of fiberoptic communications. Yisrael studied for seven years under Rav Simcha Wasserman zt”l, and for the past ten years he has been studying under Rav Gershon Bess, shlita. He has served as a science and technology consultant to numerous Rabbanim on many of today’s important Halachic issues.
He also founded Maalot Los Angeles, a school where post-seminary students receive undergraduate instruction in both Torah and secular studies. In this book, Yisrael applies modern tools of information science to Torah study, introducing a revolutionary method for simplifying even the most difficult Talmudic discussions. Yisrael and his wife now live in Israel.
