Double Maths First Thing is like a tall, dark stranger with some coal and some whisky Hello! My name is Colin and I am a mathematician on a mission to spread mathematical joy into 2025 and beyond. I note that 1/1/2025 is the first day since September 25th, 1936 where the day, month and year…
Numerical coincidences for 2025
There seem to be a lot of numerical coincidences bouncing around concerning the new year 2025. For example, it’s a square number: \( 2025 = 45^2 \). The last square year was \(44^2 = 1936\), and the next will be \(46^2=2116\). The other one you have likely seen somewhere is this little gem: that 2025…

A Puzzle about a Calculator
It’s now been a year since I took over the puzzle column at New Scientist and turned it into the BrainTwisters column. By way of celebration, I thought I’d write up an interesting bit of maths behind one of the puzzles, which I made a note of at the time and have been meaning to…
Double Maths First Thing: Issue 10
Because there’s really no excuse for ho-ho-ho-CAH-TOA Hello! My name is Colin and I am a mathematician on a mission to spread mathematical joy and delight, without recourse to magical reindeer. Somewhat embarrassingly, I’ve shown up for class outside of term-time but then… so have you. Let’s make the most of it! This week’s pictures…

A New Sequence!
Or The Novice’s Guide To Achieving Mathematical Immortality This is a guest post from Barney Maunder-Taylor. A great way to achieve mathematical immortality is to solve an outstanding open question, like determining if \( \pi+e \) is rational or irrational, or finding a counterexample to the Goldbach Conjecture. But for most of us, a more…
