[量子力學] 第8-2講、Feynman Path Integral(Mathematical Formulation)- NATIONAL TAIWAN UNIVERSITY



Gravitational Waves - Prof Bruce Bassett



Publicado em 1 de mar de 2016 The AIMS Public Lecture Series presents: "Gravitational Waves - Einstein's Final Legacy and a Revolution for Astronomy" By Prof. Bruce Bassett, AIMS South Africa, SAAO and UCT Abstract: Gravitational waves - ripples in the fabric of space and time itself caused by colliding black holes - were discovered last week by LIGO, opening up a new window on the Universe. In this talk we will explore what they are and why Einstein predicted them 100 years ago, how they are created and why it has been so hard to find them. We then discuss how gravitational waves will revolutionise astronomy by giving us a new sense, the only one that could potentially see right back to the Big Bang.

ATMOSPHERIC NEUTRINO STUDIES AND NEUTRINO OSCILLATION-Takaaki Kajita, Nobel physics in Stockholm December 2015-NATIONAL TAIWAN UNIVERSITY DEC 22-2015-大師開講:微中子震盪 / 2015年諾貝爾物理獎得主 梶田隆章教授-



Takaaki Kajita (梶田 隆章 Kajita Takaaki?, born 9 March 1959) is a Japanese physicist, known for neutrino experiments at the Kamiokande and its successor, Super-Kamiokande. In 2015, he was awarded the Nobel Prize in Physics jointly with Canadian physicist Arthur B. McDonald.

2015年諾貝爾物理獎得主日籍梶田隆章教授於12月22日蒞臨臺灣大學凝態中心物理­新館國際會議廳,針對〈微中子震盪Atmospheric neutrino studies and neutrino oscillation〉議題進行一場通俗演講。 臺大物理系指出,在進入千禧年之前的1998年,梶田隆章教授代表日本超級神岡微中子­探測實驗(Super-Kamiokande)報告指出,宇宙射線在大氣中產生的微中­子會進行兩種不同「味」,「渺子」與「濤子」間的轉換,顯示微中子具有質量,改變了以­往微中子無質量的核心認知,也成為未來研究宇宙的重要依據,因此榮獲2015年諾貝爾­物理獎桂冠。
