Here is a wonderful interactive essay about the spacing effect: How to Remember Anything Forever~ish. I also really like this paper about how we’ve failed to apply this result to education:

This is the current layout of my Backup System. It shows how: archive-servers.sh, offline-backup.sh, and offsite-backup.sh work. The Syncthing and Tailscale connections are not shown for the sake of clarity.

We find the height of water in a conical tank such that: $$ V = \frac{1}{3} \pi x^3 $$ given that water is flowing in at a rate $dV/dt = 1 m^3 / min$.

We find a linear system with solution set $\operatorname{Span}({ (1,0,2,3), (0,1,4,5)})$.

My daughter Mira came in to the office this afternoon and coloured.

The canonical start of a linear sequence is a point in nearest LFn string. In this simple example, there are three possible linear sequences (with the correct orientation) but only $L2, L5, R1$ has the correct start point.

I’m working with Eric Vandendriessche and Alfredo Braunstein to understand a bit about how the string figure calculus acts of canonical linear sequences.

For positive integers $m$ and $n$, let $f(m, n)$ denote the number of $n$-tuples $(x_1, x_2, \dots , x_n)$ of integers such that $|x_1|+|x_2|+ \cdots +|x_n| \leq m$.

For another discussion of this, see: From a Markov Sequence to a Heart Sequence.

This photo has a sketch of an embedding $\heartsuit_n \leq B_{2n}$.

We check a simple lemma leading up to Bessel’s Inequality. Suppose that ${e_n}$ is an orthonormal system of vectors, with a Hermititan inner product $\left\langle x,y \right\rangle$ inner product.

Three loop manipulations are shown. What should we call them?

I have wanted to build a sundial for a long time. Recently, I got inspired by Reinhold Kriegler‘s brilliant reflected sundial.

There is a webcam in my office that I use to take photos of the whiteboard. This setup was inspired by Dror Bar Natan‘s Blackboard Shots.

Dave has an amazing summation: $\displaystyle \sum_{n=1}^\infty \frac{n^{13}}{e^{2\pi n} - 1} = \frac{1}{24}$ Moreover, this is exactly equal to the integral!
