臺灣大學科學教育發展中心（Center for the Advancement of Science Education，簡稱NTUCASE）成立於2008年10月。成立宗旨乃在期許能將臺灣大學的科學研究及相關專業，貢獻於科學教育、科學素養，以及科技文化之啟迪養成，深耕在地放眼國際，將NTUCASE打造成一個以臺大為基地的華文科教資源平台。 NTUCASE採雙軌策略，藉由時興的「網路」、「傳播」，舉辦各項科教活動、開發科普影音網路節目、經營科普多媒體傳播，同時推動科普平面、電子出版等。以推動科學人文跨科際教育的新觀念，集結科教、科傳社群革新科學教育，開創了臺灣科學教育前所未有的紀錄。

Video Description
廣義相對論裏的黑洞容許物體掉入，但卻連光也逃不出來。 但是，41年前霍京發現把量子效應考慮在內，黑洞就會發散粒子，從而漸漸蒸發。 此現象被命名為「霍京輻射」。對於掉入黑洞的資訊，到底最後怎麼了， 至今尚無被公認為正確的解釋，但一般猜想霍京輻射或可通過量子糾纏 把資訊提取出來。然而近年來發現這樣或會導致黑洞表面終究產生極高溫的「火墻」， 摧毀任何企圖入內的物體。此演講主要講解霍京輻射的物理，以及其衍生 出的資訊遺失與火墻悖論, 並提出一些可能的解決方法。 活動官網：http://case.ntu.edu.tw/ex/Einstein 2015/12/5 pm2：00 ,臺灣大學應用力學館國際會議廳
