P05: Introduction to Light-induced Forces (淺談光力)

Light-induced force is everywhere although you cannot feel it. It can be applied to manipulate molecules in the microscopic world and drive spacecraft to travel in the universe. This talk will introduce interesting phenomena and applications of light-induced forces, from optical tweezers, which were awarded The Nobel Prize in Physics 2018, to tractor beams which used to exist only in science fictions like Star Trek.

儘管你感受不到，但是光力無處不在，它可以用於操縱微觀世界中的分子，也可以驅動太空船在宇宙中飛行。本次講座會介紹光力產生的有趣現象和應用，包括獲得2018年諾貝爾物理學獎的光鑷以及過去只見於科幻小說如 Star Trek 中的牽引光束。
