If you still have to compose the LaTeX part, then such a editor (with online formula display) is unbeatable. Note also that in the LaTeX editor quoted by Hungry, you may select whether you want transparent or some colored background and also what type of font and which font size you prefer!FridgerPS: Anybody recognizes that formula appearing twice on this page?

G is Newton's gravitational constant and units of lightspeed c = 1 are used as usual. Fridger
