A cute probability fact

On a recent UK trip, Matt Parker shared this little fact with me. He was making a video about it, so I made an animation to help explain it, which I figured would make for a nice short video.

Next transformer chapter (final version)

Here's the final version of Chapter 7 of the neural net series, about the multilayer perception blocks in transformers, as motivated by the question of how LLMs may store facts. The plan is to make...

No Patron charge for July

Hey folks,

July was a busy month for me, but unfortunately not in a way that translates very directly to new 3blue1brown content. Since progress was also a big slow in June, I’m pausing the...

First chapter for transformers (draft)

Hey folks,

This is a draft for the first of three chapters I'll add to the miniseries on deep learning, about transformers. I imagine the title for this first part to be something like "But w...

February update

Hey everyone,

I'm always disappointed if the end of a month rolls around and I don't have a video for you. I've been chugging along at the animations for the transformers project I mentioned ...

Written versions of Calculus, YouTube shorts, and other lesson supplements

Hey everyone,

I wanted to pass along a few quick updates on a few projects that supplement the core lessons. My main focus continues to be researching/animating the main videos, these are all...

X-rays "faster" than the speed of light, and more refractive index questions

Hey folks, here's an early view for the follow-up video about the refractive index, which essentially goes through a few of the questions folks asked here on Patreon.

The prism video is live!

Finally, after two months, it's out. If there's anyone you know who you think may enjoy this lesson, do consider sharing it with them.

Based on Patron comments, I ended up adding a bit more t...

Next video, early view

Hey folks, here's an early look at the upcoming video on the index of refraction.

A few sections, especially towards the end, don't have graphics yet. I know several things I'd like to change...

Hey everyone,

Thanks for all the thoughtful questions related to the index of refraction. When I solicited them in a 2023-11-10 22:50:32 +0000 UTC View Post

A draft video on proving the central limit theorem (which I don't particularly love)

Hey folks,

Last month I thought I'd put together a "quick" video offering a sketch for a proof of the central limit theorem. I edited it together most of the way, with several to-do stubs for...

Why the "central limit" is a normal distribution

Here's an early view for the next video, capping off the mini-series about normal distributions. I have just one to-do stub left in there for myself, but let me know if you catch anything else that...

Revisiting Moser's circle problem

One of the earliest videos on this channel was about Moser's circle problem, a famous puzzle where the answers seem to follow a certain pattern, but one which turns out to be misleading.
