讲座东谈主先容:
迈克尔•贝里爵士现为英国布里斯托大学荣休物理学教师,是刻下最负驰名的表面物理学家之一。贝里爵士至少在以下四个主义作念出根人性的孝敬:几何相位、光学奇点、量子暧昧和渐进分析,其中以他名字定名的贝里相位和贝里曲率的看法已成为繁密物理学分支的基本参议器具。在纯数学范畴,贝里爵士在1989年料理了渐进分析范畴一个斯托克斯提议的、长达150年悬而未决的艰难,他在黎曼猜思主义亦有紧迫孝敬。贝里爵士1982年当选英国皇家学会会士,1995年当选伦敦数学学会会士以及好意思国科学院外籍院士,1996年被英女王封为爵士,获取的奖项主要包括狄拉克奖、沃尔夫奖、和洛伦兹奖。
讲座现实:
Classical optics is an ancient subject. But only now have we discovered a library of ‘elementary forms’, that describe light in our everyday world. Rainbows, twinkling stars, sunlight sparkling on water, and the dancing lines of light on the bottoms of swmming-pools, can be understood in a unified way using modern geometry. On fine scales, where wave interference must be considered, different geometry describes the secret lines of light’s darkness, and the fingerprints of polarisation in the blue sky – invisible to us but perceived by bees. Poets and novelists, as well as painters, have sometimes represented optical phenomena in ways surprisingly close to those of physicists. The talk is nontechnical and entirely visual.
