清华大学的物理课 网友：虽然看不懂 但是大为震撼

这种现象被称为超导体的抗磁性，是超导体的基本特征之一，也就是麦斯韦尔效应。超导体在外部磁场中会排斥磁力线，使其在外部磁场中形成一个磁力屏蔽。

30年前就有了，中国人科学知识都低，大惊小怪！很普通的高温超导，液氮冷到-200左右就可以实现超导磁悬浮

低温超导体， 差不多绝地零度了 还在实验室阶段

还得学好物理呀

I’m telling you, there are millions to be made by the first company that figures out how to finance small, bootcamp-style trade schools. 🧰 Average course: $4–5K 💼 Most grads land jobs within weeks 💵 $25–30/hr starting pay These aren’t 4-year degrees. They can pay it back in months, not years. Who’s going to build this? Because the demand is massive. Bonus: tag who you think can build this. @Codie_Sanchez @JesseTinsley @mikeroweworks @mhp_guy @CoFoundersNik @JohnCena
