本期节目话题背景

　　最近，有同学问了我这样一道题“Describe a person who contributes to the society”，我是一个很喜欢探索科学的人，因此我经常会听一些关于科学的播客，或者看一些跟科学相关的书籍，因此，我认识了哥伦比亚大学的教授Brain Greene。他到底是怎样的一个人物？我们一起来聊聊吧！
　　我认为Brain Greene教授为人类社会做出的最大的贡献就是把科学上非常难以理解的话题，以更简单、更有趣的形式分享给大家，这是一件非常值得敬佩的事情，而且也是我认为十分必要的一件事。

　　本期Part 2 话题

　　How you knew him/her
　　What type of work he/she does
　　And explain why you think he/she contributes to the society

　　本期节目话题参考文本

　　I would like to talk about professor Brain Greene, who is a world-renowned professor of mathematics and physics at Columbia university.
　　I mean, I don’t know him personally but I have read his books on physics and listened to most of his podcast. I think he is one of most important science figures in today’s society and one of his biggest contributions is to be the founder and creator of the “world science festival”.
　　The World Science Festival is an annual science festival produced by the World Science Foundation, a non-profit organization in NY.
　　It is basically like a science talk show during which famous scientists around the world are invited onto the festival to discuss a certain topic, for example, the multiverse, relativity, or neuroscience. The goal of the festival is to cultivate a general public informed by science, inspired by its wonder, and convinced of its value.
　　The festival was founded and created by Brian Greene, who serves as chairman and chief executive. Without him, none of this would have been possible. Each year, millions of people around the world watch this festival either live or on social media. Therefore, I think his biggest contribution is that he took difficult topics in science and communicated to people in an easier and more interesting format, which I think it is amazing and absolutely necessary.
