Algotithem  (example: sorting algorithem) 冒泡排序 \r\n\r\n#### 3. 加密学 解释了对称加密之后指出了不足点，然后介绍了非对称加密 \r\n\r\ndiscreate function 就像颜色，很快可以得到结果，但是从结果很难推出输入是什么。\r\n比如你混合两种颜色，这个很简单。如果把混合的结果恢复到原来两种颜色就很难。\r\n\r\n用混合颜色很好的解释了 非对称加密的原理\r\n\r\n\r\n#### 4. Machine Learning 机器学习\r\n\r\nML 里你不用编程去解决问题\r\n而是编程让机器去从经验中学习，总之就是让机器去自学\r\n\r\n举例，机器学习用于推荐系统\r\n\r\n#### 5 Biology as Computation   就是编写DNA代码，达到想要的目的。\r\n目前的应用都只是剪切这个物种里的一个基因，用到另一个物种里。是剪切粘贴。\r\n人类还不能自己创造指定功能的基因。\r\n\r\n\r\n---\r\n\r\n1和3举的例子很好，建议看视频去。  \r\n其他的我觉得没啥用（起码对我来说）"}}
