COMBIEN DE TEMPS DURE UN MOIS LUNAIRE ? | Torah & Science

Each month, the moon waxes and wanes before our very eyes. For centuries, we knew how to read it, without being able to truly measure it. Today, science gives a figure accurate to the millionth: 29.530589 days between two new moons. And the most astonishing thing? The Hebrew calendar, transmitted nearly 2,000 years ago by Rabban Gamliel (Talmud, Rosh Hashanah 25a) – without a telescope, without an atomic clock – already gives 29 days, 12 hours, and 793 halakim. That is, 29.530594 days. A difference of less than half a second, a precision greater than 1/100,000. In this third episode, Rabbi Nathaniel Mimoun places the two documents side by side—the measurements of modern astronomy and the calculations of our Sages—from Rabban Gamliel to Maimonides, from Babylon to the masters of Kabbalah, and recounts this astonishing encounter, simply. 📖 Based on the book "The Revolution." ⏱️ CHAPTERS 00:00 Introduction - Two Perspectives on the Moon 00:30 The First Commandment and the Phases of the Moon 00:54 The Jewish Month: The Molad and the Crescent 01:33 How Long Does a Cycle Last?
