At the same time,\u0026nbsp;a new generation of atomic clocks is leading us to re-define what we mean by time. \u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESuper-cold atoms, with temperatures that can be below a billionth of a degree above absolute zero, use\u0026nbsp;and allow tests of\u0026nbsp;some of Einstein\u0026#39;s strangest predictions.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis public lecture will be a lively, multimedia presentation, including exciting experimental demonstrations and down-to-earth explanations about some of today\u0026#39;s hottest (and coolest) science.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EAbout the Speaker\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWilliam Daniel Phillips is an American physicist who shared the 1997 physics prize with Steven Chu (US) and Claude Cohen-Tannoudji (France).
