Newton’s True Genius: The Canon, Not the Apple
Points clés de l'épisode « Du canon à la Lune : la découverte de la gravité » de ScienceEtonnante, publié le December 5, 2025.
In "Du canon à la Lune : la découverte de la gravité" (ScienceEtonnante, December 2025), isaac Newton’s breakthrough was not the apocryphal falling apple, but a thought experiment involving a cannon. By visualizing how a projectile could orbit Earth if fired fast enough, he unified terrestrial ballistics with celestial mechanics, proving that the Moon is essentially a falling cannonball governed by the same inverse-square law of gravity.
