Notices by Colin Beveridge (icecolbeveridge@mathstodon.xyz)

Say, fellow denizens of the mastosphere: I am on the lookout for new consulting projects (or a job, under the right circumstances). I am good at solving problems, usually maths ones, and usually with code (mainly Go recently, but also Python; a bit of Fortran and R in my past). I'm happy writing tests, docs and training. Let me know if you know of anything that needs a Colin!

Today, I dragged @StuartBeveridge to Chorley to see a fantastic bridge.

Because the railway and canal are at such a sharp angle, a normal arch wouldn't stay up. Instead, the stones are hand-carved in curves so that the joins between them are perpendicular to the bridge's weight.

Hello! My name is Colin and I am a mathematician.

My PhD was about the magnetic field on the Sun. Today is the anniversary of the Carrington Event, a massive geomagnetic storm that led to intense auroras and reports of telegraphs failing, shocking their operators, and in some cases working while disconnected: https://en.wikipedia.org/wiki/Carrington_Event

Meanwhile, if you need someone who can solve problems and code a bit, get in touch!

@thomasfuchs @ids1024 Agreed! I should make clear that I don't go into the library and repeatedly check out my books, tempting as it is.

@ids1024 @thomasfuchs I'm in the UK. Maybe we're more enlightened over here! https://en.wikipedia.org/wiki/Public_Lending_Right

@thomasfuchs Published author here. I get paid somewhere in the region of 5-10p (let's call it a dime) every time someone checks one of my books out of a library, on top of the royalties from the library buying it. So yeah, if someone borrows Basic Maths For Dummies[^0], I get compensated *whether or not it turns them into a highly paid professional*.

TIL about umbral calculus: https://en.m.wikipedia.org/wiki/Umbral_calculus

"Construed literally, it is absurd, and yet it is successful." It seems to have been used for about a century despite nobody really having an explanation for why it worked.
