OT - 3b1b did an interesting video on the epidemic modeling [0] that shaped my thinking a bit on the lockdown and caused me to lose a few friends to argue against the prolonged lockdowns. I believe he used the same technique deployed by major media institutions and health organizations. Basically the interesting conclusion was unless you apply a very rigorous lockdown (CCP style) the virus ultimately spreads. All you…

Yes, basically everywhere lockdown started as a “flattening the curve” and then at some point became “everyone needs to be kept out of harms way until everyone is vaccinated”.

That isn’t an American experience it was the same almost everywhere lock down was initiated.

So I am not sure it makes sense to blame it on Trump haters.

For anyone interested in the code used in his animations, the repo is here: https://github.com/3b1b/videos It's pretty impressive. A lot of work goes into these videos. My other favourite YouTube math guy is eigenchris. His tensor calculus series is legendary: https://www.youtube.com/playlist?list=PLJHszsWbB6hpk5h8lSfBk... In complete contrast to 3b1b, eigenchris creates his videos entirely in PowerPoint, which makes…

PowerPoint is a decent tool for creating lightweight animations. With the right use of tools like morph transition etc. one can achieve pretty decent looking or even professional looking animations of concepts. I have also used PowerPoint to create web application wireframes, design concepts, Logos and website graphics, icons, repeating fill patterns, arbitrary vector graphics, etc. I guess one strong point is how ea…

Yeah I briefly got really fancy with InDesign at work when I was much younger and arrogant. And then I had to hand off the project.

Instantly broke. Spent a good 3 hours that day porting to PowerPoint.

Seriously, his explanations on topics go well beyond the lectures some of my professors provide and could probably benefit a lot of students if given as a resource... If only academia wasn't so distrustful of those outside their circles...

But he's not even outside their circles right? Doesn't 3b1b have a PhD? I can tell you at least that we watched some 3b1b videos in my university undergrad math classes last year!

Wikipedia thinks he has a Bachelors from Stanford[1]. That said, I love his videos too. I started with The Essence of Linear Algebra[2], which is just fantastic and really shaped my intuition for the topic.

Grant Sanderson does not have a PhD, he holds a Bachelor's degree in Mathematics from Stanford University.

Earlier quoted context omitted.

3b1b uses a python library for creating those videos. https://github.com/3b1b/manim As far as a math educator/communicator, one of my favorite videos of his is the video on the monster. https://www.youtube.com/watch?v=mH0oCDa74tE Also since we're talking about powerpoint here you should probably see this Matt Parker video about excel being used in ways it shouldn't maybe? https://www.youtube.com/watch?v=UBX2QQHlQ_I

> 3b1b uses a python library for creating those videos. Which he also wrote!

Superb library!

However why are all the examples using the antipattern? :

  from manimlib import *
The community version continues the same practice: https://docs.manim.community/en/stable/tutorials/quickstart....

That is asking for trouble once you start importing more than one library.

the most important thing for me in his videos is how he strives to explain the topic from a first principles thinking perspective. if i had someone explain linear algebra the way he does in his youtube channel, i would have enjoyed and absorbed it much better than I did during my classes. while the professors did a decent job in explaining linear albegra and its usefulness among various topics around us, they did a p…

I'm amazed of the amount of great resources available to students today to learn complex topics. I'm not even that old (late 30s) but the only real resources available when I was in school were other textbooks. There were some math blogs but they were mainly focused on higher-level mathematics.

To add a different recommendation on math, Michael Penn's math channels on youtube are great. It helping me study some more advanced topics.

I've watched a number of Penn's videos and generally enjoy them but they really seem to be targeted to the math major types. I have a BS and MS in electrical engineering which did require some high level math but not to the degree needed to fully grasp what he's showing. Nothing wrong with that but people without college math study are usually going to be overwhelmed.

Some of it requires study I think, so not like just watch the video and yep it makes sense, but using them as lectures while also reading other texts on the same subject.

His differential forms playlist is great. Goes well together with eigenchris' lectures on Tensors for Beginners, I think.

And I was an engineering major but took a lot of math.

Could anyone recommend a calculous book with lots of exercises (and their solutions)? 3Blue1Brown videos are great, but they're more for building the initial intuition. I'm looking for something that I can practice to "get used to" calculous.

I did a lot of research on this at one point, and these are what I ended up going with and was quite pleased. You can probably find them cheaper at abe books or somewhere, I'm just linking amazon for the ease (hopefully amazon links are allowed)
