7月的在线学习
首先批评一下自己，没有按时完成读书任务，本来这个月底应该读完《Essential C++》了。
实际情况是只看了前面一点儿，后面就没有毅力读下去了。
主因应该是大量的时间拿去了娱乐，目前PSO2的角色已经玩掉了130多小时，如果这时间全拿去读书，真心不少。
可是，俺也是人，确切的说，是个懒人，真心是只靠deadline驱动……而且自己定的deadline死活无效，罢了，以后再说吧。
Coursera的三门课结课了半个月之后，拿到了两份电子证书，Logic与compiler的，
Machine learning的那份因为最后一次Assignment的deadline比较长，得等8月中才能拿到。
新的三门课下来了，其中有一门，Listening to World Music，因为需要大量英文写作被俺放弃。
然后只剩两门，Quantum Mechanics and Quantum Computing与Introduction to Finance。
先说后者，容易得像小学数学应用题。大概因为只是入门的关系吧，反正比想象的容易。
再说前者，太难了，一上来就是波粒二象性，让我感觉回到高中时的物理课。
记得高中时的物理老师叫WHJ，他当时一而再再而三地夸我“这才是学物理的脑子”。
可惜我非常事与愿违地跑去学化学，然后随着时间的流逝，各种忘光光……
如今再度拾起物理也是一窍不通，真担心这门课无法pass。
希尔伯特空间，In
内积计算公式都改了，[a,b]与[c,d]的内积是
其实纯计算还好，一旦牵扯到那些个参照系啊、测量啊，头都大了。且看这道题：
A qubit is either in the state
到底什么叫best distinguishes between these two possibilities啊？
好吧，我没学懂，我继续爬文……
再摘抄一段教学视频中的话来结尾，这次是Gautam Kaul在Welcome Video中说的
Finally. This class is about ambiguity and learning. And I would encourage you to take that attitude towards it. Okay? One last thing, which I feel compelled to talk about because I have prepared most of the class, and I want it to share with you. Why did I say yes to it? Why did I choose to do something online? The first reason is I believe education should be accessible to all. Why do I believe that? Because I believe education almost is like a right. It's almost like a right to breathe. I do have strong views about it, but I genuinely believe that education makes you become empowered. The most valuable investment you could ever make is education. What do I mean by that? Remember, if you want electricity, which is good, you're willing to burn coal. However burning coal leads to some problems, some costs on society, and on you too. Education is an investment that largely gives your benefits. Why wouldn't you want to do that? Why wouldn't you to make an investment in yourself. My goal, in this investment, is to empower you not to be dependent on a coach like me or any other person. But to take this class and say, I can do it too, and that's the beauty of education. I'll make couple more points and then we'll see each other in about a week. This has been a real challenge for me as a teacher. I've always wanted to be able to teach everybody, every single person and that's not been easy and I don't think I can teach everybody. But this experiment, hopefully which becomes an ongoing activity in my life, I feel like this gives me the ability to reach out to you on a one to one basis and hopefully. Make you learn, and be excited.
