re: 17 equations that changed the world

Navier-Stokes is easily the most important today, imo.
Fourier transform close second.
Fourier Series and Fourier transforms by hand are easily some of the most difficult things I have ever done. The Stokes general theorem is basically the father of calculus, and as a consequence, quantum mechanics.
In terms of importance, that list should include both Bernoulli Equation for hydraulics and the Euler-Bernoulli Beam Theory for bending beams and columns. Life would be pretty impossible without structures or water flow, especially in SELA.
Eta-
It's pretty amazing to think that can be derived into Green's theorem, Fundamental theory of calculus, divergence theorem, etc.

The Fourier transform is pretty fricking fascinating.
Laplace also.
you just finish differential equations? I'd hardly call them fascinating.

I never understood the importance of i^2=-1. I understand what it means but how does it help anything? This just assigns i, i^2, i^3, i^4 to numbers instead of showing sqrt(-1)

In short it created the mathematics to support electricity. You wouldn't have alternating current electricity without i, or as electrical engineers call it- the j component.

Bernoulli Equation for hydraulics
Bernoulli is contained within Navier-Stokes.
Stokes is vastly more powerful than Bernoulli.

this list is total horseshite without Ohms Law

List is fine. Ohm's law is just Drude model.

You forgot....
The angle of the dangle is directly porportional to the mass of the arse provided the heat of the meat is constant!

I haven't been to my math class in a couple of weeks, and I have a day to teach myself Fourier shite

SIAP. Bernoulli's eq is derived from NS.
Yeah you're right. It's a simplified form of the incompressible NS. I had forgotten that I learned that using the PDE form of NS. PITA. That's different from Stokes Theorem as I am sure you know.

R+L=J
List is suspect.
