Wolfram works with the full mathematical expression tree. It works very well in practice but the equality test is undecidable in general.

I ran into this issue once while trying to render the Mandelbrot set while learning Haskell. It defaulted to a rational type based on two bignum integers with unlimited precision. With every Mandelbrot iteration* the integers doubled in siz

> Nothing is mining the web for maths, and semantic markup for maths buys you nothing. I find that rather unfortunate. A math search engine that find sites with equivalent formulae (or segments) would be quite useful to me. Of course, th

I think fallacy 2 is the big one, and not just in the AI field. Sometimes a simple lookup table (or some other 'dumb' model) works well on tasks that humans generally consider 'hard'.

How do these ToF systems deal with multiple sensors pointing at the same scene? I've seen it work with two ToF sensors, but haven't been able to find a good explanation for how it works.

I find the general idea of treating differential equations as infinitely dimensional linear systems quite powerful. I was first introduced to the concept while studying quantum mechanics, but applications are everywhere.
