New blog post: Visualising the Legendre Transform. In which, I show how the Legendre transform can be derived in a visual way by thinking about the relationship between two ways of describing the same curve.

I’ve spent far more time than I’d like to admit regenerating plots to make axis labels legible in papers. I’d never taken the time to think about how to choose font sizes systematically but this really takes the guesswork out of it.

While collecting references for the post, I found that the idea is not an original one: the same idea was previously explored by @FrnkNlsn in "Legendre transformation and information geometry"

The key idea is that the curve of a convex function can be described both by the points that make up the curve and by the set of lines which never cut into the area above the curve
