There is really no better way to communicate mathematics. The result is really polished. It doesn't matter if you're talking about Maxwell's equations: \$\\nabla \\cdot E = \\frac{\\rho}{\\varepsilon_0} \\\\ \\nabla \\cdot B = 0 \\\\ \\nabla \\times E = - \\frac{\\partial B}{\\partial t} \\\\ \\nabla \\times B = \\mu_0 \\left( J + \\varepsilon_0 \\frac{\\partial E}{\\partial t} \\right), \$ Schrödinger's equation \$i \\hbar \\frac{\\partial}{\\partial t} \\Psi = \\left[ \\frac{-\\hbar^2}{2m}\\nabla^2 + V \\right] \\Psi, \$ or \$$L:V\\to W\$$ a linear map from \$$V\$$ to \$$W\$$. I can not think of a better way of rendering mathematics than with \$$\\LaTeX\$$. Even more valuable than looking pretty, \$$\\LaTeX\$$ is typed without using the mouse. Being able to simply *type* mathematics really is a joy. Now, \$$\\LaTeX\$$ is not something that you just sit down and learn. I find it best to have in mind what you want to write before you write it. Then look up what you need to write your document. The hardest part is starting. It can really help to have an example. It's even better to make changes and see what the result is. Below I believe is a good example of a document that helps explain what \$$\\LaTeX\$$ can do and how to do it. I also have linked to the resulting document below the source. .. listing:: LaTeXsample.tex latex |pdf|. If you want more information I find |NssItL| to be a close to exhaustive resource.
