The big letter L

After several people commented yesterday on my post about numbers, I’m encouraged 🙂

So here are some thoughts about graphs. We see graphs all over the place, don’t we? So many kinds of graphs for so many kinds of data. Somebody who shares my enthusiasm has made a website about the marvels that are graphs.

I’ll never forget the moment when my Maths teacher at school, Mr ….., drew a big letter L on the whiteboard and asked us who invented those two lines. The answer, apparently, is that Descartes dunnit. In the 17th century! Yes, it’s that recent. There’d been millennia of fab Maths before that but Descartes invented the big letter L. Since then, other people have added to his idea and now if you feel brave you might like to take a look at what Wikipedia says about Cartesian coordinates. So much fabulous science has grown around the big letter L.

I’ll come back to this but before I do the errands that are calling me today, I’d like to mention what Mr ….. said. He said I was the best girl mathematician he’d taught. Never mind his sexism (he was of his generation) he’d noticed that I had the mind of a mathematician. Hah!

I wrote a PhD about veterinary parasitology so that's the starting point for this blog. But I'm now branching out into other areas of biology and into popular science writing. I'll write here about science that happens in landscapes, particularly farmland, and about science involving interspecific interactions. Datasets and statistics get my attention. Exactly where this blog will lead? That's a journey that I'm on and I hope you'll come with me.
