OU KOSHER Chametz Sheavar Alav haPesach: The Supermarket Controversy By Rabbi Yaakov Luban

An exciting aspect of Torah study is the application of the age-old principles of halachah to the modern world in which we live. Thus, as an example, there is obviously no Talmudic discussion about the propriety of walking past a motion detector on Shabbat, yet contemporary posekim (halachic decisors) have analyzed this issue and found relevant source material in the vast sea of halachic literature. By identifying fundamental principles and concepts, halachists have addressed she’eilot (questions) that run the full gamut of modern human experience.
