Counting From Scratch: Castrovalva and The Number Zero
If you’re reading this on the day of publication then it is Friday 11th April 2025, the day before the start of the new season of Doctor Who, which we will call Day Zero. To be more precise, it’s Day Zero of Season Two (2025) of Doctor Who, or it’s Day Zero of Series 15 if you’re ignoring the break in numbering since the Disney co-funding partnership in 2023, or it’s Day Zero of Season 41 if you’re also ignoring the break in numbering since the show’s 21st century revival in 2005 (respect!).

Thinking about the new series of Doctor Who has made me think about fan-counting systems, which made think about the number zero and Castrovalva, which made me think about new beginnings, which made me think about the new series of Doctor Who, which made me...

NEW BLOG! In which I realise I still have more things to say about maths teachers in Doctor Who. Yes I know, there’s actually more than one!
Doctor Who and The Maths Teachers
I have a question for you: do you know how many beans make five? I can hear you already shouting back at me. “It’s half-term week! School’s out! Let the teachers rest!” But I think there’s always time to learn something new. Especially when it’s about maths!…

Doctor Who has had a number of teachers appear over the years, starting with Ian Chesterton and Barbara Wright back in 1963, who taught science and history respectively.

It’s 3pm and I’m trying to work but all I can think about is what if Mary Whitehouse was alive and kicking in the year 2025.
What does she think about TikTok? MrBeast? The Online Safety Act?
And then she discovers there’s hot people in Doctor Who, has a heart attack, and promptly dies again.

As a mathematician and a Doctor Who fan, I adore Christopher H. Bidmead’s work on Doctor Who, which showed how maths and science can be powerful, mysterious and poetic. Castrovalva remains a personal favourite. I wish I had the chance to meet him. RIP

Just finished watching Wednesday Season 2: Part One. It’s perfectly fine, and generally an improvement on Season One IMHO.
But I’m seeing a bunch of discourse saying it’s bad because it’s “not faithful” to the source material. And regardless of whether it is, I find that argument baffling.
