What are the uses of differential calculus in your life?

Are you in academia or industry (I'm guessing academia if you're working on low-level numerics)?

Are you doing modelling with a VoF type method, or something more exotic?

Academia too - PhD student. I work with something more exotic than a VoF-style method, but it has it's roots in VoF. Trying to combine the mass-conserving nature of VoF whilst retaining sharp resolution of the fluids interface by using flux-splitting schemes combined with gradient limiters to keep things sharp. The trick we have up our sleeve is access to high-res MRI data for the velocity and chemical data, so we can validate our codes quite readily with realistic test cases

Is this all some inside-joke the rest of OCuK'ers don't get?

WHAT THE HELL IS EVERYONE TALKING ABOUT IN THIS THREAD!!! Might as well have been in Arabic.

P.S Just don't blow the planet up..please?

I use differential calculus whenever I want to remind myself how grateful I am that my day job doesn't involve differential calculus

I use it to work out when the bog roll will need replacing.

Since I'm still learning this kind of maths, I'm just using it in questions.

And then in maths at uni, to answer more questions!

After I'd "learned" about this stuff, I promptly forgot it and have never had use for it since.

I always wish that I was one of those people that "got" maths. Stuff like this was an epic struggle when I was doing Electrical/Electronic Engineering. I have no issues with applied stuff as far as using formulae goes but all this off-the wall stuff doesn't compute for me. My brain isn't wired for it.

I haven't used A-level maths since.... A-levels.
