Next lockdown math lecture in ~2.25 hours

Thanks you all for the support during this rather different experiment.  So far it's been fun, if mildly nerve-racking.  This upcoming lecture will be on the basics of complex numbers. 2020-04-24 16:48:40 +0000 UTC View Post

For those who weren't able to make it live, here is the first episode of this experiment went.

Livestream lessons

Hi Everyone,

For the next few weeks, in parallel with other projects, I will be doing some live streamed lectures aimed at serving the function of a high school class.  The first one wil...

Updated probability density function video

Edit: Bizarrely, Patreon replaced the video above with a static image.  Here is the final video, with edits based on your feedback: 2020-04-09 01:26:31 +0000 UTC View Post

London performance

When I was in the UK last month, Matt Parker invited me to join a monthly show that he (along with Helen Arney and Steve Mould) put on called "An Evening of Unnecessary Detail".  It's a sort o...

Simulating an Epidemic (early view)

Hey Everyone,

This is a video (draft) using SIR models to simulate an epidemic and tweak various parameters controlling the small society of wandering dots it applies to.

I'll be doing...

Bayesian updating and probability density functions

Hey everyone,

Here's the next installment of the three-part sequence leading to the beta distribution.  It introduces Bayes' rule in a context beyond the usual binary outcome introductor...

Which rating is better, mathematically speaking?

Hey everyone,

Here is the first of three installments for the next probability topic.  Imagine you're shopping online, and see three different sellers of the same product with the follow...

Exponential growth with epidemics

I, er, got a bit distracted and made a video about exponential growth.  The plan is to publish it tomorrow morning, if you catch any errors, do let me know!

Edit: And now it's...

Video status, emerging from the rabbit hole, and England.

Hi Everyone,

First off, there will be a new probability video within the next week.  Thank you for your incredible patience on this front!  The topic, broadly speaking, is a case st...

TEDx

I spoke at TEDx Berkeley was this past weekend, and even got to meet a couple of you there, which was fun.  It's about what makes people engage with math and the relationship between utility a...

January update

Several times recently I've received update posts from people I support on Patreon that open with something like "I know I've been slow to publish content recently..."  In reading those, I alw...

The quick proof of Bayes’ theorem

This is a quick footnote to the first Bayes' theorem video, not the part 2 referenced at the end of that video.  Enjoy!

New video: Bayes' theorem, and making probability intuitive

What I initially thought would be a simple massaging of an old unpublished video quickly turned into doing a completely new project.  I think it's for the best, too, as there were enough thing...

The "moduli space" of triangles

Hey folks,

I wanted to share a small thing I've made, which will likely be incorporated into a full video around February.

A few months ago, David Eisenbud, director at MSRI, asked if I...

Q&A, windy walking edition (rough cut and early view)

Hi Everyone,

I made a simple Q&A video to mark passing 2^21 subscribers.  I decided to try a stark contrast in style from the usual faceless, minimalist, animated style characterizin...

New video, the hyperdarts puzzle, done with Numberphile

Hi Everyone,

Thank you for your patience recently.  The video showing the hyperdarts puzzle, with the solution and the surrounding commentary on why I like it, is finally out!

Hey everyone,

Following up on the last post, I'd like to try out switching this page to a model...

Per month vs. per video, which do you prefer?

Hey everyone,

Currently, the structure of this Patreon page is that people make pledges to contribute for each new video produced on 3blue1brown.  Or rather, each one I choose to mark as...

Final prime spiral video (quick error check before release)

Hi Everyone,

Here's the final form of the prime spirals video, now with an added ~8 minutes on Dirichlet's theorem + some thoughts on the value of "pointless" mathematical play.

If you ...

Prime spirals (early view)

Hi Everyone,

As usual, I'd like to give you an early view of the current project before it goes live this coming Sunday.  I really enjoyed getting your input last time on the Windmill pu...
