I'm not sure which forum to post this in.

Post your favorite mathematical or physics-related equation.

You may use these, provided by 01101001 in another thread.

and this,

Or you could hot-link the image from Wikipedia: (this is also my favorite equation)

-W=B+P+X

Where W is for wife, B is for beer, P is for Pizza, and X is for Xbox

I knew it was a bad idea to post this in the OTB.

Well for me w=0 b=0 x=pc games

There was a thread about that, I believe.

((ACP + SCP/4)/YM) + 15% = GFW

Where:

ACP = accountable cigar purchases - these are the purchases that your wife
knows about in full such as purchases you made in her presence, ones with
a credit card trail, etc.

SCP = secret cigar purchases - these are the purchases that you manage to
sneak in under her dollar sensing radar. Cash only, no bags, she never
sees them enter the domicile - you know the drill.

YM = years married

GFW = Gifts for Wife required to offset total cigar purchases and thereby maintain marital bliss

Okay...in seriousness, since I have a history as an avionics repair technician, I'd have to say one of my favorites would be Ohm's Law and it's variations.

I cant go past the classic line from Winston Smith in his diary entry in 1984

1 + 1 = 2 Accept this, and all else follows

How about the Navier-Stokes equations?

1ly= 9.46 x 1,000,000,000,000 km = 63,240 AU





Thats a long walk

I'm a bit of a fundamentalist.

I can't decide between:
0 + 1 = 1 + 0 and 1 + 0 = 0 + 1

I'm pretty sure that

I like the formulas for a line integral, among others. In terms of importance, however, I might pick Taylor's formula first. I'm a simpleton.

This was the first one I thought of too, but then I thought about a little bit larger picture and decided that my favorite was the general conservation law.

The rate of change of something in a control volume = fluxes of something in and out of that volume + sources or sinks of something. Fluxes can be advection or diffusion.

And that's it, that's the basis of the Navier-Stokes equation which is a conservation of linear momentum in Newtonian fluids. But, the overriding conservation equation works with anything: Non-Newtonian fluids, solids, and the conserved quantity can be a lot of different things: mass, both linear and angular momentum, energy, electric charge. Maxwell's equations can be written in conservation form, too.

Conservation looks like a pretty simple statement, but it is an exceptionally powerful tool for solving problems and analyzing situations. And, despite what the perpetual motion machine makers think, there isn't away around it -- at least not in the universe we inhabit.

Oops!

Well, I suppose my fave would have to be E=mc^2.
