量子纠缠是物质和时空的本源
热度 11 2015-12-5 18:58
有些人认为(包括我),量子纠缠是一切物质的本源(见《物理学新的革命》 http://chuansong.me/n/1098981 甚至是时空的本源(见《爱因斯坦不会高兴的》 http://chuansong.me/n/1983915 说量子纠缠是一切物质的本源不是忽悠。因为我们可以从量子纠缠推导出物质的运动方程,像麦克斯韦方程和 ...

The second quantum revolution 第二次量子革命
热度 24 2014-10-8 08:53
Physics, in particular, condensed matter physics, is a very old field. Many people are thinking that the exciting time of physics has passed. We enter the begining of the end of physics. The only important things in physics are its engineering applications, such as optical fiber and blue LED. Howe ...

A new discovery: 1D topological order beyond FQH states
热度 9 2014-10-4 20:46
http://www.scientificamerican.com/article/majorana-particle-matter-and-antimatter/ This is an exciting discovery. However, I must point out that the new discovery here is not a new “Majorana particle”, but the two-fold topological ground state degeneracy (see http://en.wikip ...

什么是高手
热度 34 2014-8-26 15:30
中手:作别人说好的东西,作的很好。(考试第一,奥赛金牌) 高手:作自己认为好的东西。让别人作自己说好的东西。让别人跟着自己的标准跑。 中国媒体网页追捧一个人,常常说此人多么“中手”,不说此人多么“高手”。这反映了不知什么是“高手”。中国要成为科技强国,要知道“高手”是什么。别努力了半 天,总是 ...

中国封锁Dropbox (China blocks the Dropbox)
热度 17 2014-6-27 01:08
看来,中国封锁了Dropbox。没有Dropbox的,我没法做研究。我所有的研究论文都在Dropbox上。 我们应该送话出去,让中国政府解除对 Dropbox的 封锁。 It appears that China blocks Dropbox. I cannot do research without Dropbox. All my research paper and proposals are on Dropbox. We should send words out t ...

Category theory for dummies (范畴学是关系学)
热度 10 2014-4-12 22:16
Usually, when we try to understand an object, we like to divide the object into smaller pieces (or more basic components). If we can do that, we say that we gain a better understanding of the object. This is the reductionist approach. But there is another way of understanding. We do not think abo ...
