Pick a quadratic. Will it factorise? @Pecnut and @mscroggs investigate in this blog from the archives chalkdustmagazine.com/blog/man

Looking for a bit bigger ? My Christmas crossnumber, inspired by the amazing @chalkdustmag conundrum, is here once again! nollakohta.fi/2018/12/jouluris

@petrilaarne This looks good, I'm going to print a copy to solve over Christmas. You should submit a puzzle to the @chalkdustmag puzzles page.

@ColinTheMathmo I've think I'm using \param instead of \epsilon (and set the value of \param in the preamble) because I've already swapped notation: it's typical to use $\gamma$ for the parameter in question, but I noticed after draft 1 I was already using $\gamma$ for something else. Let's hope I remembered this and used \param everywhere...

Aaarg, I'm using $\epsilon$ and $\varepsilon$ (for two different values) in the same equation. I fear it may be time to burn this laptop and start my PhD again from scratch.

This has to be the weirdest setting for a sci-fi novel. This plot synopsis is so bizarre!

@Breakfastisready This sounds amazing, I've ordered a copy from Amazon!
