Maths, clearly

Colin Beveridge, Town Bridge

I am a freelance mathematician, which means I solve problems about how things relate to each other. Often, it means fixing the annoying problem you’ve been putting off because it needs too much concentration. I strive to make things as simple as possible, while making you look – and feel – smart.

Email me on if there’s anything I can help you with!

If you follow me on Twitter or LinkedIn, you might have noticed me asking “how can I help you this week?” on a Monday.

This is an experiment. It’s partly because I like helping people, but it’s also partly research (I want to know what people struggle with, so I can cut my consulting cloth accordingly.)

It’s also a chance for me to think about what I like to do, and to keep a record of the kinds of things I can do.

This week’s little bits of help:

  • A student in Nigeria was looking out for free conferences on maths and AI. I was able to connect them with someone who could help (thanks, Peter!)
  • A maths teacher was hunting for resources on algorithms. I pointed them in the right direction.
  • A programmer was struggling with an error message in the Python package pymem (not my area of expertise). I found the problem and advised on how to fix it.

And a bigger one:

  • An analyst needed help estimating parameters and their error rates for a sophisticated statistical model. I dug into the problem and gave suggestions of appropriate methods they could use (including hill-climbing and simulated annealing).

If you have a mathematical problem I might help with, drop me an email ( – if it’s something I can offer quick advice* on, there’s no charge.

If you have a bigger problem, I offer a bespoke consultancy service. Again, please email me ( and we can discuss details.

* What exactly “quick advice” means varies depending on how busy I am. Generally, if it’s something I can answer in a couple of emails without writing any code, it’s quick advice.
