埃莉斯·卡茨 (Elise Cutts): 为什么一天会有两次潮汐？

为什么一天会有两次潮汐？

17 世纪时，艾萨克·牛顿首次提出对潮汐的引力解释。正如他所说，潮汐是由天体运动编排而成的，而地球的潮汐，主要由月球驱动。然而，这种关系的确切性质实际上相当微妙。埃莉斯·卡茨 (Elise Cutts) 解释了太阳和月球是如何影响潮汐的。【导演：雷米·坎斯 (Rémi Cans) 和 Atypicalist，旁白：亚历山德拉·潘泽尔 (Alexandra Panzer)，配乐：萨利尔·巴亚尼 (Salil Bhayani) 和 cAMP Studio】。

Earth experiences two high tides every day, the result of a delicate dance between the Moon’s gravity and the planet’s rotation. The Moon pulls ocean water toward it, creating a bulge, while the Earth’s motion forms a second bulge on the opposite side. Ancient armies like Alexander the Great’s once faced tidal phenomena such as a tidal bore along the Indus River, centuries before Newton explained the science. The Sun’s gravity, local geography, and even the movement of distant planets all weave together to produce tides that shape our world and others.
