講座人介紹:
邁克爾?貝里爵士現(xiàn)為英國(guó)布里斯托大學(xué)榮休物理學(xué)教授,是當(dāng)今最負(fù)盛名的理論物理學(xué)家之一。貝里爵士至少在以下四個(gè)方向做出根本性的貢獻(xiàn):幾何相位、光學(xué)奇點(diǎn)、量子混沌和漸進(jìn)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(xué)分支的基本研究工具。在純數(shù)學(xué)領(lǐng)域,貝里爵士在1989年解決了漸進(jìn)分析領(lǐng)域一個(gè)斯托克斯提出的、長(zhǎng)達(dá)150年懸而未決的難題,他在黎曼猜想方向亦有重要貢獻(xiàn)。貝里爵士1982年當(dāng)選英國(guó)皇家學(xué)會(huì)會(huì)士,1995年當(dāng)選倫敦?cái)?shù)學(xué)學(xué)會(huì)會(huì)士以及美國(guó)科學(xué)院外籍院士,1996年被英女王封為爵士,獲得的獎(jiǎng)項(xiàng)主要包括狄拉克獎(jiǎng)、沃爾夫獎(jiǎng)、和洛倫茲獎(jiǎng)。
講座內(nèi)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.
