I look at a basic indispensable everyday tool such as Fourier Transform. Swapping space and time, or time and space. There’s always a compromise, a little nugget of uncertainty but it works quite well all things considered, once you get the parameters right.
It’s used everywhere today. It’s almost reversible but “not quite” and it’s that “not quite” that I find fascinating.
I recognize the name – and I’ve heard of “Science without numbers” but I hadn’t looked at it yet.
With the intuitionalism, that’s basically my view of things. I traced where it came from for me a few years ago.
I was still learning the tail-end of arithmetic just prior to Pre-Algebra when I first encountered programming. BASIC. It’s within that form that I learned logic as it’s used in computers.
Much later, just a few years ago, I found out what the kind of logic used in computers is and it’s not quite the same as what’s used in regular mathematics or regular logic.
