Computer Applied for First Time to Jewish Religious Law Needs

SIGN UP FOR THE JTA DAILY BRIEFING

The Association of Orthodox Jewish Scientists reported today the first appearance in book form on the applications of computer technology to measurement of time elements required for Jewish Religious Law observance. The book, “Jewish Chronomony,” was written by Dr. Leo Levi, president of the association and assistant professor of physics at City College of New York. Chronomony refers to scientific methods of reckoning and measuring time in relation to dawn and dusk, noon and midnight and related major time shifts.

Dr. Levi made extensive use of a computer in preparing tables which include a system for converting between civil and Jewish dates, a permanent Gregorian calendar, latitudes and adjustment-to-standard time constants, and related aids to calendar calculation.
