“Shape” by Jordan Ellenberg: I Was Lost. Then I Realised the World Was Getting Bigger.

By Sivapriya Mothilal Bhagavathy — R&D Leader, Mum, and Occasional Confused Reader

I started Shape thinking: “Right, this is about geometry. Probably boring.”
Then I was halfway through and thought: “Wait… is this about Covid? And politics? And why my teenage daughter’s art looks like a fractal?”

By chapter four, I was genuinely lost.
The book was hopping from Fibonacci to famine, from voting systems to viral spread — like a very clever, slightly chaotic squirrel on a caffeine high.

I nearly put it down.
Then I thought: “Maybe I’m missing the point.”

So I carried on.
And then — boom — it clicked.

You prove one thing… and suddenly, the world gets bigger.

It wasn’t a single idea. It was a pattern.
One truth opens a door. Then another. Then another.
And before you know it, you’re standing in a whole new landscape — full of questions, wonder, and the occasional crooked Fibonacci spiral.

Here’s what I’m taking from it — not from grand projects, but from thinking differently:

  1. All hype isn’t true. Be a bit sceptical.
    Just because it looks elegant doesn’t mean it’s right. (Cough, revolutionary energy tech.)
  2. Maths is hard. Let’s admit it.
    If we pretend it’s easy, students won’t ask questions. And if they don’t ask, they’re not learning.
    So: “This is tricky. Let’s figure it out.”
    (Even if I’m still figuring it out myself.)
  3. Fibonacci wasn’t the first. And we’re still reinventing wheels.
    The sequence was known in India centuries before Fibonacci. Now? We’re doing the same thing with clean tech — in labs across the globe.
    Is that progress? Or just a very expensive game of “Who’s got the same idea?”
  4. If you’ve never guessed wrong, you’re not guessing hard enough.
    I’m going to try to be wrong more often.
    (Even if it means my energy model fails spectacularly. Progress!)
  5. I don’t want AI to give answers — I want it to ask better questions.
    “Why are we assuming the grid is centralised?”
    “What if people don’t want to change?”
    Now that’s the kind of thinking that moves mountains.
  6. Even Nobel winners can be petty.
    Ronald Ross spent years grumbling about recognition — and honestly? I get it.
    But the real win? The work. The curiosity. The trying.
    So keep going. Even if no one’s watching.

Final thought:
Shape didn’t change my projects — not yet.
But it changed how I think.
And that’s the best kind of shift: quiet, slow, and full of potential.

So if you’re into maths, meaning, or just want to feel slightly more human while sipping tea — go read it.
Just don’t expect it to be easy.

(And if it is? You’re probably missing the point.)

Until next time,
