Pick a quadratic. Will it factorise? @Pecnut and @mscroggs investigate in this blog from the archives http://chalkdustmagazine.com/blog/many-quadratics-factorise/

Looking for a bit bigger #maths #puzzle? My Christmas crossnumber, inspired by the amazing @chalkdustmag conundrum, is here once again! https://www.nollakohta.fi/2018/12/jouluristikot-2018.html#english

@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.

@mscroggs (It's equivalent to \(K_{26}\))

@christianp @andrewt @chalkdustmag @Pecnut also this year's card of the first without a year on it

I recommend @mscroggs's maths puzzle advent calendar. http://mscroggs.co.uk

@alexdbolton \(\mathrm{e}^{x-1}\)

@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...

Do you love maths magazines and the first number that is neither prime nor semiprime? Then you'll love our 8th issue! http://chalkdustmagazine.com/

Do you love maths magazines and vertices of cubes? Then you'll love our 8th issue! http://chalkdustmagazine.com/

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!
