48.You have to learn quantum mechanics.
Why? Because looking back from now on, all the natural science knowledge discovered by human beings, except general relativity, has been gathered in the field of quantum mechanics. Looking from now on to the future, if there is another revolutionary breakthrough in human natural science knowledge, it is very likely that it will start from quantum mechanics.
Therefore, quantum mechanics is a unique and promising way for human beings to understand the world. In this course, there are no difficult formulas and theorems, and there are only 14 lectures. However, it can ensure that an ordinary person has a good understanding of quantum mechanics.
你一定要学点量子力学。
为什么？因为从现在往回看，人类发现的那些自然科学知识，除了广义相对论，都已经汇集在了量子力学这个领域。而从现在往未来看呢，人类的自然科学知识如果再出现革命性的突破，有很大可能性还是会从量子力学开始。
所以，量子力学，已经是人类理解这个世界的一种独特的，而且还非常有前途的方式。李剑龙老师的这门课，没有艰深的公式定理，体量也只有14讲，但是，可以确保一个普通人在认识上对量子力学登堂入室。
