This evening marks the beginning of the Days of Awe, starting with "Jewish New Year's" (Rosh HaShannah) and culminating in the Day of Atonement (Yom Kippur). This year, I thought I'd let Dr Amy Farrah Fowler Mayim Bialik and her friends do the honors of explaining some of the symbols and rituals.
May you and yours enjoy a happy, healthy New Year.
