Ugh, my long-standing hosting provider (several wordpress sites, but freedom to set up all sorts of PHP/Python/etc frameworks) is shutting down. Any recs for a reliable, not too expensive, alternative? (I pay about $10/mo currently).

Good morning, everyone! My name is Colin and I am a mathematician. It is 10 years since I first saw a copy of Basic Maths For Dummies (still available wherever good books are sold).

So rather than a generic “what can I help with?”, today I want to hear your burning questions!

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

If you’ve got a problem, and no-one else can help, and the A-Team is out buying a “No fools are pitied in this vehicle overnight” sticker, maybe you can hire* me.

* You don’t always have to hire me. Quick stuff? No charge.

Hello! I checked the calendar, and it is Monday. I checked my passport and my name is Colin. I checked my job description and I’m a mathematician. And, as always, I’m here to offer whatever assistance I can.

So, what can I help you with this week?

Right now, I’m putting the finishing touches on a biomechanics project to find the angles between the various parts of a leg as it exercises. I had hoped to use quaternions, but sadly Euler angles were the order of the day. It was still fun!

My name is Colin, it is Monday, and I am a mathematician.

This week, I've mainly been learning javascript libraries and trying to reverse-engineer the geometry of Wembley Stadium from photographs in the hope of pinpointing a laser pointer.

Also, here’s a fictionalised version of something I helped with last year:

What can I help you with this week?

Hello! My name is Colin and I am a mathematician. It is Monday and I’m here to solve problems. What can I help you with this week?

Here’s a (fictionalised and anonymised) account of one problem I cracked last week:

I've set up a site called My aim is to collect ambiguous, inconsistent, or just plain unpleasant conventions in mathematical notation.

It's a wiki, so you can edit it. Please add in any examples that come to mind!

hey is there anybody on the fediverse who lived in germany between like 1982-1984 and listened to NDR

or anyone who was active in the music scene there around that time

or even any radio DJ's from that era

because the world could use your help solving the mystery of the most mysterious song on the internet

basically, all you need to do is read the wikipedia article and listen to the song and hopefully you'll recognize it and remember who it is

boosts appreciated, you never know, fedi might be the place to crack this case!!! :boost_ok:

My name is Colin, and I am a mathematician. If you’re into calendar-related coincidences, today is both Tau Day (6.28, if you write the date wrong) and a perfect day (28 and 6 are perfect numbers). Is there anything more meaningful I can help you with this week?

OK, Mathstodon: you know the drill: I plotted something, and you’ve got to guess what it is. For the third time: what’s the plot? (Postcards for responses I deem to be the winners.)

Hello! My name is Colin, I am a mathematician and it is Monday: what can I help you with this week?

What's the most tedious problem you have at the moment?

According to 99% Invisible, today is Flag Day. How can I help you raise your standards or succeed with flying colours this week?

My name is Colin, I am a mathematician, and I’m here to help. Let me know how!

What, EXACTLY, is your problem, buster?

No, hang on, wait a minute. Wrong tone entirely.

My name is Colin and I’m a mathematician. I love solving problems. Do you have one I can help with?

The results of this episode of What's The Plot are up:

A postcard for @pretentious7 -- if you let me know privately the best way to get it to you, I'll pop it in the post :-)

Hello, Mastodon! My name is Colin, and I am a mathematician. I play by the rules and still get results*. What can I help you with this week?

* mainly. No guarantees.

I plotted something… it looked interesting… that’s right: it’s time for another round of What’s My Plot?

Tell me what you think the logic behind this diagram is, and YOU could win a coveted postcard!

I stumbled down a rabbit-hole and came across Almost Pythagorean Triples (APTs), integers such that \(a^2+b^2=c^2+1\).

I reckon that if \(T\) is any triangular number and \(2T = QR\), (with \(Q\) and \(R\) positive integers) then:

* \(a = Q-R\)
* \(b = \sqrt{4QR+1}\)
* \(c = Q+R\)

forms an APT. I *believe* all APTs are of this form; those with three odd values appear twice, and those with only one appear once.
