New video! Some light quantum mechanics

Hey everyone,

This is one video in a two-part collaboration with MinutePhysics.  The video o...

Sneak peek of (one of) tomorrow's video(s) with MinutePhysics

Hello $2+ Patrons,

Henry (from MinutePhysics) and I have been working on a pair of videos, one one Bell's inequalities, and one that's a primer on some of the wave math that underlies quantum.  ...

Some E&M wave animations

Hello $4+ Patrons,

If you're curious to get a sneak peak on what I'm working on, here are a few animations for an upcoming video.

I just noticed in looking at this that some of the arrows in t...

Update

Hey everyone,

You might have noticed that the probability series has been a little slow to develop, so I thought I'd give you all a little update for what I'm working on.  Right now I'm in the ...

Podcast!

Hey everyone,

As mentioned in the last video, I'm starting a podcast with two very smart and likable guys I met at Khan Academy, each named Ben.  You can find it at 2017-08-15 01:03:53 +0000 UTC View Post

New video! A trick to visualizing higher dimensions

Hello all,

This is a fun one on trying to grapple with higher dimensional spheres.  The puzzle that it centers on is a very famous example of where our intuition for higher dimensions breaks do...

Reaching goals

Hey everyone,

As some of you may have noticed, this Patreon page recently passed one of the goals I put out several months ago.  Specifically, here's how it was described.

New probability video! "The independence assumption"

Hey folks,

I have a new probability video for you.  The plan is for this show up as chapter 3.   Preceding it, but not yet made, there will be an introduction to basic combinatorics (...

Re-recording of an old favorite (no charge of course)

Hey everyone,

I've been working on the next probability video, which involved sort of revamping my original plans and pulling out some content as a separate video.  Anyway, in part of the write...

How much counting to include in EoP?

Hey Patrons, 

So I'm putting together a video on the binomial distribution meant to go pretty early in the series (likely video #2 or #3).  The plan is for this to follow a video covering ...

Cryptocurrency supplement: How secure is 256-bit security

Hey everyone,

As promised, here is the supplement to yesterday's video.  No charge, of course, since this is an add-on to a different main project.  I had a lot of fun putting this togethe...

New video! Ever wonder how Bitcoin (and other cryptocurrencies) actually work?

Hello all,

One thing I've enjoyed doing in past videos is putting together a narrative for how the viewer could reasonably have invented the relevant piece of math themselves.  Admittedly, ther...

Sneak peek for the 2's: Cryptocurrencies

Hello $2+ patrons,

Here's a draft for tomorrow's video about the protocol behind bitcoin and other cryptocurrencies.  The only part I haven't put in yet is a little preview for the supplement v...

Photo thanks for the $2+

Hey $2+/video Patrons,

Given that I had originally said I'd share with you some form of photographic thanks with a $2 bill, while taking some photos on my flight back from VidCon today I thought I'd...

Thoughts on the classic Bayes' example

Hello again,

Following up on the last post, this video goes into one of the most famous examples of Bayes' theorem.  Part of why I wanted to include it in the series is to give my own take on t...

Bayes' rule!

Hey everyone,

Although I have yet to decide on the  full table of contents for the probability series, the most obvious video to include is one covering Bayes' rule.  So I decided to start...

New video! All possible pythagorean triples, visualized

Hey everyone,

This is kind of a fun one.  The first time I ever learned about the formula for generating pythagorean triples, it was in the context of stereographically projecting rational poin...

Animations for the fours

Hello +4's,

The upcoming video is on finding all possible pythagorean triples.  Here are a few excerpts from animations I'm working on.

New video! Pi hiding in prime regularities

Hello all,

You might notice that this is the longest video I've ever made, coming in a 30 minutes.  It's one of my favorite pieces of math, and exemplifies why I love number theory so much. &nb...

Early view of tomorrow's video: Pi hiding in prime regularities

Hello $2+ Patrons!

I've decided to change the $2 reward from the photographic thanks to instead giving you all a little early view of stand-alone videos that I finish before the Friday that I plan t...

Sneak peek for the fours

Hello $4+ patrons,

Here are a few preview animations from the upcoming video, which will be entitled "Pi hiding in prime regularities".  As usual, these are just the animations themselves out o...

Share your thoughts on probability

Hello Patrons, 

Now that calculus is wrapped up, that means the next big "Essence of" project will be on probability.  Even though I won't start working on it for a few weeks, instead focu...

Higher order derivative footnote

Hello all!

I made a small footnote video on higher order derivatives to precede the Taylor series video.  No charge, as this is a purely supplemental and smaller video.

Taylor series video!

Hey Everyone,

The last installment of "Essence of calculus" is on Taylor series.   I enjoyed reading through the comments on the previous post about what made the topic click for several p...

When did Taylor series click for you?

Hey everyone,

I'm putting together a video on Taylor series, and I don't know about you, but when I was a student first learning this topic I definitely did not appreciate how important they are. &n...

New video: Averages with integral, EoC Chapter 9

Hey everyone,

This is the follow-on discussion of integrals.  Originally I had intended for this to have a wider scope, but I chose to narrow in on the example of finding an average for a few r...

New calc video! Integrals and the fundamental theorem of calculus

Hello Patrons,

After the desert of differentiation, we are finally at the oasis of integrals.  You may notice that much of this video overlaps with the (new) first chapter of the series.  ...

New version of chapter 1 for Essence of calculus

Hey everyone,

I decided to create a different version for the video introducing the series.  There's no charge here, since it's a remake and not a new video.  As always I'm all ears to hea...

New calc video! Limits.

Hi Patrons,

The next installment of "Essence of calculus", about limits, is now ready.  I appreciated the comment thread about whether or not to include a discussion of the epsilon-delta defini...

Some early limit animations for the fours

Hey 4+ patrons,

Here's a couple animations from the upcoming limits video.  As you can tell, I ultimately did decide to go with including some talk about the epsilon-delta definition in this on...
