講座人介紹:
邁克爾?貝里爵士現(xiàn)為英國布里斯托大學榮休物理學教授,是當今最負盛名的理論物理學家之一。貝里爵士至少在以下四個方向做出根本性的貢獻:幾何相位、光學奇點、量子混沌和漸進分析,其中以他名字命名的貝里相位和貝里曲率的概念已成為眾多物理學分支的基本研究工具。在純數(shù)學領域,貝里爵士在1989年解決了漸進分析領域一個斯托克斯提出的、長達150年懸而未決的難題,他在黎曼猜想方向亦有重要貢獻。貝里爵士1982年當選英國皇家學會會士,1995年當選倫敦數(shù)學學會會士以及美國科學院外籍院士,1996年被英女王封為爵士,獲得的獎項主要包括狄拉克獎、沃爾夫獎、和洛倫茲獎。
講座內容:
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.
