3Blue1Brown的社会影响
5G互联网新时代的到来预示着我们未来的教育必定是网络教育的时代。 可能以后的教育模式就是全世界只有一个或者少数几个世界上最好的老师来讲课，大家都听这几个老师的课。老师可以从讲课任务中解放出来。取而代之的是可以注重回答学生的疑问和个性化辅导学生。学生大部分是看视频，看笔记。这可能是一个专业团队所完成的事情。3Blue1Brown告诉我们其实个人也可以做的。这种科普小视频的线上教育的社会影响必定是革命性的。因为这样可以解决贫富差异问题。现在社会的贫富差异问题很明显。穷人如果没有条件受到好的教育就会越来越穷。现在，如果穷人能买得起一台手机，他想学习，那么他就可以接受到世界上最优质的教育。世界上最顶尖的人为他录制的视频。如果你说真正的穷人买不起一台手机。那我也没办法。我觉得这个政府应该能帮助解决这个问题。因为每个小学生配一个能看视频的手机，甚至是接受一些捐赠的二手的手机，国家应该能付得起这个钱。总之，好的线上教育资源无疑可以解决贫富差异这个问题。3Blue1Brown在线上教育这一点上无疑是有深远的历史意义的。现在国外也出了非常非常多的优质教育资源。比如可汗学院，Coursera，edX，Mooc等等。
3Blue1Brown是否付费
纯免费。当然如果做得好有人愿意赞助就可以收。对于这一模式在3blue1brown作者本人的阐述更为幽默有趣和清晰。Support — 3Blue1Brown里面的漫画令我印象深刻。
A: So what do you do? B：Oh, I make videos about math.
A: Wait, how does that work? B: People pay for them.
A: Oh, so like a paid course? B: Well, no, everything is free.
A: Wait, what? B: I know, it's weird.
这种形式就是说对公众完全免费，但是公众如果觉得有帮助可以自愿打赏。有兴趣才看，没有兴趣不看。不浪费别人的时间。只靠优质资源吸引听众。视频精益求精。
简介里面说：the channel no longer does sponsored content.意思就是不会收钱制作付钱方要求制作的内容。这对各方是一件都有好处的事情。
在这一点我想评论一下万门大学，喜马拉雅，得到等中文的线上教育平台。这些平台相对于3Blue1Brown的有点是都有一个巨大的公司在后面运营。然后最优质的内容必须付费。我能理解这种付费经济。因为现在老师要做一个优质的课程非常非常不容易，老师也要挣钱才能生活下去。他肯定不能无偿工作。但是3Blue1Brown的境界又高了一级。他所有的课程都是全免费的。而且他没有广告。就算有也是他推荐的真的优质的资源。不是说为了赚钱打的广告。而且做得非常非常精致。可以说到极致了。用户觉得好会自动给他赞助。我觉得他在公益事业上也已经做到了极致。因为所谓付费知识这种经济。对普通人是有很大的意义的。普通人能够花少量的钱收到非常好的教育。但穷人就不行了。但是他这个，如果真的是穷人的话，他完全可以免费享受这些优质的教育。等他能够用他所学的知识挣到钱的时候，他再去回馈3Blue1Brown。
3Blue1Brown的视频如何制作
我下面随便抄几段吧。以后再更新。总之现在很多人被这种风格深深吸引了。开始做一些用他这种包的短视频。
What do you use to animate your videos?
I create most of the animations programmatically, using a python library named "manim" that I've been building up. I’ve also used Grapher for a number of 3d animations.
It’s open-source on github, and asmall communityhas emerged of people who use it, but before you dive in I feel like a warning is in order. This is something I put together with my own use case in mind, never really meant to be a professional product that’s consistently maintained for others. It's not that I want to discourage others from doing similar things, quite the contrary Ilove when that happens, but often my workflow and development with manim can make it more difficult for an outsider to learn than other better-documented animation libraries, like Matplotlib and Mathematica, or other tools built for math visualization like Geogebra, Desmos, Grapher and more.
他使用的这个包比较复杂。所以可能更适合我的是Mathematica或者后面他推荐的一些math visualization的tool。
I also get worried when I hear people ask things like “how do I sync up narration into manim”. This is just a tool for spitting out the individual mathematical animations to be edited together later. For goodness sake, use traditional video editing software for as much as you can!
这里他建议我们使用传统的软件，并不要学他的软件，因为可能学他的软件需要耗费大量的时间，而且纠结一些奇怪的问题。
There are aspects of producing videos with a self-made tool like this that I find quite pleasing, but which are pleasing precisely because it's my own. It enforces a uniqueness of style, for example, which is by its very nature a benefit that can't be shared. There's also a certain freedom in being able to tear up the guts of the tool every now and then when I feel a change is in order, since backward compatibility needs are very limited when you only care about videos moving forward. Not exactly the best practice from a collaborative standpoint.
The channels I know who took inspiration from 3b1b and did it best, like Primer or Jazon Jiao, found or created the tooling that worked best for their particular content.
Will you please make a video on ________?
TOPIC SUGGESTIONS GO HERE
Note, requests I get through email are just about guaranteed to be ignored, since that reddit thread is where I look when considering what people are asking for and how others respond to each request with upvotes and comments.
In choosing a video topic, the aim is to find a story that has the best chance of deepening people’s relationship with math, and which I am personally most excited to describe. Sometimes that means explaining a topic many people find confusing in what I hope to be a halfway novel way, other times it means finding topics people wouldn’t even know to ask for. Many times, there's a worthy topic with clear demand, but I simply don’t feel I have an original or captivating enough way to approach.
Also, if your request is one from multivariable calculus (e.g. Lagrange multipliers, the Jacobian, Stokes’ theorem, etc.), there’s a good chance I covered it in some ofmy work at Khan Academy, either in video or article form.
他说如果有request的话不要给他发邮件。有一个专门的地方可以给他提供建议。
You are not allowed to re-upload the content on your own channel, and such re-uploaded content will be taken down as a copyright violation. I know that might seem harsh, and that many re-uploaded dubbed videos are done in good faith trying to spread math around the world. However, there need to be consistent principles around how the lessons are put out under the channel name. To take one potential problem, there is otherwise no mechanism for preventing the insertion of unwanted promotional or sponsored additions, or other sorts of edits that misrepresent the original intent of a video.
这个上面说不允许重复upload video。因为要consistent。其实这也和他的哲学有关。就是单纯靠优质内容吸引听众。他不会花钱推广自己。但很多看过他视频的人就会忍不住要推广他的视频。因为这真的是好东西。和现在很多自媒体刷粉，标题党，刷播放量，哗众取宠的形成了鲜明对比。他这些播放量和粉丝都是真实的播放量和粉丝。其实重复upload video已经是很轻微的刷播放量的行为了。不他坚决不允许。
I’ve solved a famous unsolved math problem/I’ve developed a novel idea. Will you check it for me?
Unfortunately, no.
There are two important things to note here: 1) I’m not a research mathematician, so I wouldn’t be the one to ask. 2) There’s too little time as it is to read and learn all the things I’d like to read, so I have to draw certain boundaries on where that time goes.
如何对待民科。
Will you speak at my event?
Maybe! Feel free to share the details through the contact form below. Just know my main focus will always be the videos, so talks are typically kept to a minimum.
他主要精力还是放在制作视频上面，少量讲talk。
Can I use/license these videos?
Under the standard YouTube license, you are free to embed the videos in your own site or blog as much as you’d like, as long as it is not behind a paywall. If you want to use some of the visuals in a classroom, or for a talk/presentation, by all means, feel free to do so. In both cases, attribution is of course appreciated.
If you have a commercial product and wish to license the videos to include in your product, feel free to send an inquiry with the contact link below specifying the details.
关于share，他说可以share，但是不能behind the paywall。允许在classroom和talk里面插入他的视频。真的是一个很纯正的理想主义者。
All the messages are read, but we hope you understand not all can get a personal responses.
他会阅读所有信息。
3blue1brown的模式是只做英语版本。这样的话有人可以帮忙翻译。这样非常好因为可以节省翻译的时间，让志愿者做这件事情。
我自己看3Blue1Brown的体验
其实很多东西我自己有学过。但还是忍不住要看他的视频。然后就会有一种全新的体验。有的我以前学过的东西。比如牛顿力学里面小滑块碰撞。高中的时候同学经常问我一些牛顿力学的题。有时候他们会问我为什么你会做。然后其实我很想说我脑子里是这副动画但是又没法画出来。看到他这个视频我就非常感动。这些真的是当时我脑子里显示的东西。要是当时问我问题的同学多看看这些视频。那不就自动会做题了吗。
上面说的是我学过的，脑子里有比较好的图像的科目。有些科目是我学过了，但是脑子里没有很好的图像的科目，比如傅立叶变换。其实我脑子里就是公式嘛算嘛。他竟然能把傅立叶变换做成一个音乐。太厉害了。这个对我自己的已经学过的知识也是很好的整理。
最近疫情他也出了很多能跟上时代的东西。比如如何控制疫情。就是他自己从simulation的角度来分析这个事情。然后他的结论是封城封国并不是本质。因为封城封国只是一时应急的对策。让感染人数一下子先降低到可控范围。如果封城封国之后不能大规模检测那封城封国是白封了，因为最后第二波又会起来。到了可控范围就可以开始大规模检测了。感染一个隔离一个。他做了一个动画表明这些simulation的结果。反正现在这已经是大家共识了嘛我就不用叙述了。但是他这个视频刚出来的时候我还不知道这一点所以刷新了一下我的世界观。然后看这个视频胜过看千千万万的自媒体疫情分析文章。
