One of many advantages of the Techexplorer is that the source may be written not only in MathML, but also directly in TeX or LaTeX. Fine, so let me do several experiments.
First, let us write down a matrix.
Fine, now we should add a nonsensical expression with some different colors:
How quickly can I write down the CP-violating topological term of four-dimensional gravity? It is
That's enough for now. If you want to know how can you write mathematics like the equations above on your web pages, simply click "View/Page Source" and search for the word "embed" (without quotation marks). Paste the "embed" ... "/embed" section onto your web page and edit it: it is self-explanatory and the main thing inside that you will modify is a TeX source.
Unfortunately, this kind of mathematics cannot be posted as comments - neither the slow ones, nor the fast ones.
Some people may ask: am I also able to write a more difficult mathematical expression?
Well, this is what one obtains for a twistorial sum after contour-integrating. ;-)
