Should NVIDIA use the F-word to respond to their intransigence ?
I actually don't use a lot of geometry in my job, but I use the basic skills of logic and proofs that I learned in geometry. I don't often solve algebraic equations but I find myself tutoring my employees in the logic of intervals. Calculus was a drudge and I almost never integrate a function, but the concepts I learned about functions I use every day. I'm not sure you can use functional programming without exposure to calculus. Almost every math subject has an ulterior motive. Geometry is there to teach you logic. Pre-calculus is to teach you about functions. Calculus is the first math where you're introduced to infinity and infinitesimal entities. Without that math I'm not sure your mind has expanded enough to work for my company.
I don't expect programmers to solve differential equations in front of me, but I doubt their technical literacy if haven't done it at least once. You don't have the tools to manage complex projects without knowing about diff Q. Likewise, you can't be a computer scientist without discrete math -- you just wouldn't have the mental tools to address the subject. Sure, you could stumble along, but you would just be depending on someone else who did the math.

I'm a mathematician, not a physicist. In special relativity the Lorentz transformation has a singularity at the speed of light. Its perfectly defined below and faster than the speed of light. Richard Feynman suggested that unless the math prohibits it, it will be found in nature. Of course, if we see a particle hitting another before it was emitted, we'd likely interpret it as the target "pulled" the particle from the emitter. This explains the alternate view of physics -- all matter emits dark, and light bulbs and stars suck the dark in. Mathematically it makes just as much sense as emitting massless photons. Who's going to buy the idea of a massless particle that goes the speed of light? Its crazy talk.
This is just a reminder that like economics, scientific method is really a confidence game. Its all a matter of whether you believe the rules stated so far are consistent.
