 Posted: 14 Jan 2009 06:45:23 pm    Post subject: The goal is go through the alphabet (english and greek) and come up with something that letter is used for in physics, either as a variable representation (V = velocity) or as units (m = meters). So, getting things started here's what I know (I didn't feel like going through the greek alphabet): A/a = acceleration B/b = Banana! I can't think of anything C/c = Capacitance D/d = dt (kinda cheating) E/e = Electric Field strength F/f = Force G/g = Universal gravitation constant H/h = Planck's constant I/i = Current J/j = unit vector in y-direction K/k = unit vector in z-direction L/l = direction cosine from x-axis M/m = direction cosine from y-axis N/n = direction cosine from z-axis O/o = unused, too similar to 'zero' P/p = Pomegranate! I can't think of anything Q/q = Charge R/r = Resistance S/s = Curve position T/t = Temperature U/u = Internal energy of ideal gas V/v = Velocity W/w = Width X/x = X-direction component Y/y = Y-direction component Z/z = Z-direction component

A/a = Avagadro's Number B/b = Bohr's atom C/c = Centroid D/d = Dalton's atom E/e = Euler's number F/f = Feynman G/g = Gauss H/h = [s]Horepower[/s] Horsepower (D'oh! At least I didn't spell it with a "wh") I/i = Imaginary number J/j = Joules K/k = Kelvin L/l = Lift M/m = Maxwell's laws N/n = Newtons O/o = Orbit P/p = uhhh..."P" orbital! Q/q = Quarks R/r = Radius S/s = Shell/SubShell T/t = Torque U/u = Unununium (the l-l-lamest name for anything ever) V/v = Valance W/w = Watt should I put here? X/x = X-ray Y/y = Young's modulus Z/z = Z-TransformLast edited by Guest on 14 Jan 2009 08:25:53 pm; edited 1 time in total

 Posted: 15 Jan 2009 07:38:48 pm    Post subject: Latin characters not yet used (and improvements on some really simple ones ) d: distance m: mass n: principal quantum number Greek letters (this would be so much easier if these could include uses in mathematics): alpha: alpha-particle (helium nucleus) beta: beta-particle (e- or e+) gamma: position vector delta: functional derivative epsilon: vacuum permittivity zeta: lag angle for helicopters (had to cheat using wikipedia for this one ) eta: index of refraction theta: azimuthal angle in spherical coordinates iota: one little bit? kappa: curvature tensor lambda: wavelength mu: coefficient of friction nu: wave frequency xi: generic eigen-function omicron: asymptotic order (Landau O notation) pi: parameter group for Buckingham pi formulation rho: density sigma: sigma particle tau: torque upsilon: upsilon particle phi: phase chi: electronegativity psi: wave-function omega: angular frequency
