Klaynos Posted October 7, 2006 Share Posted October 7, 2006 Oh, and mine is an exponential fourier coeficient for a fourier series. http://en.wikipedia.org/wiki/Fourier_series#Canonical_form it's cn=cj-2N-1 Oh and I see where Matt is comming from, this should not be in maths.

YT2095 Posted October 7, 2006 Share Posted October 7, 2006 well Matt should have simply asked for it to be Moved then, anyway, I`ve Moved it. Link to comment Share on other sites More sharing options...
Severian Posted October 7, 2006 Share Posted October 7, 2006 I quite like the QED lagrangian: [math]{\cal L} = \bar \psi (x) \left( i \gamma^{\mu} \partial_{\mu} - m - e \gamma^{\mu} A_{\mu} \right) \psi (x) - \frac{1}{4} F^{\mu \nu} F_{\mu \nu}[/math] Link to comment Share on other sites More sharing options...
woelen Posted October 7, 2006 Share Posted October 7, 2006 Write out the tensor contractions, then you get a really longwinded thing Link to comment Share on other sites More sharing options...

gib65 Posted October 8, 2006 Author Share Posted October 8, 2006 Oh and I see where Matt is comming from, this should not be in maths. In that case, my apologies. Sometimes these topics can be tricky. Thanks for all the formuli everyone. I've now got a lot to choose from. Link to comment Share on other sites More sharing options...
ajb Posted October 8, 2006 Share Posted October 8, 2006 Equations only "look" complicated because of the notation used. Simple looking equations may hide very deep facts behind the notation. Part of mathematics is trying to find "better" notation so that things look "obvious". So really, you have to think about the notation used rather than the equations themselves.
