# LaTeX Spoken Here!

This is a test of LaTeX on the site*.

The first equation I shall try is the following (for more on unpacking this equation and its meaning, see this post and links therein):

Yay! It works. I have implemented it in the comments too. So now we can have a new, sharper tool for our discussions and arguments.

Use: Type simple LaTeX commands enclosed between [ tex ] and [ / tex] (remove the spaces between the things in the square brackets) and it should work once you submit.

Enjoy.

(*I got around the problems of not being able to have LaTeX running on my host. Hurrah! The compromise I used means that the LaTeX is not as nicely formed as it could be, but it’s good enough! Learn more about latexrender and mimetex here.)

Darn, my hodge star is out. Quite nice! Just needs a bit more practice for use in comments. The case is really hard to prove though–took me hours one night

WOW!!! Let me have a go. This is a real long shot:

OK, that was too ambitious. Sigh. But THANKS, Clifford! Is there a free blogging setup where one could do this? Or maybe we should just ask Google nicely…

• Hmm, how about some little arrows…

• That’s just plain geekalicious!

• OK, lets try again…

(By the way, that’s the Lie derivative of a 1-form.)

• Yes, this is really fun! And I have good news for people with blogs in Blogger or in servers that do not support latex. Have a look here. Peter Jipsen of Chapman University has written ASCIIMathML a great javascript program that converts ASCII notation (more or less the one used in math and physics newsgroups, and of course in blogs, although not this one any more:-)) to MathML. Firefox rendering is great, although you may need to download some fonts. IE needs a plugin and rendering is not so good. Now, you are supposed to upload the javascript file to your server, but I suspect that it will work also if you put the content of the file in the head of your Blogger template. (Be warned though that the file is 42K, and that I have not tried this, I just assume it will work.)

If you do not want to risk this, there are two more solutions mentioned in the page given above. The first one are the ASCIIMath Image Fallback Scripts which use a public mimetex server (meaning you do not have to have mimetex in your server), and the second is LaTeXMathML, which as you may have guessed translates latex notation to mathml using again a public server if you cannot upload the file in your own.

Enjoy!

• The posts here are like the doodles that psychologists fool you into making, when they want to figure out what kind of crazy you are.

• Oh, I’ve got you all figured out, all of you!

Last try. Delete immediately.

• OK, I did not mention the most important thing (for hardcore latex users). All the above programs (ASCIIMathML etc.) also recognize latex notation.

• The converse of the Principle,

is called the Indiscernibility of Identicals. Sometimes the conjunction of both principles, rather than the Principle by itself, is known as Leibniz’s Law.

• http://en.wikipedia.org/wiki/Perfect_fluid

In physics, a perfect fluid is a fluid that can be completely characterized by its rest frame energy density Ï and isotropic pressure p.

In tensor notation, the energy-momentum tensor of a perfect fluid can be written in the form

where U is the velocity vector field of the fluid and where Î·Î¼Î½ is the metric tensor of Minkowski spacetime

How did you get the latex to show on wordpress without having it downloaded to a server?

• Here’s a test:

• another test:

• Failed to rasterize \begin{picture}(0,0)(-320,-20) \put(0,0){\circle{24}} \put(-4,3){\circle{4}} \put(4,3){\circle{4}} \put(-3,3){\circle*{2}} \put(3,3){\circle*{2}} \put(0,-1){\oval(12,6)[b]} \put(0,-7){\line(0,1){3}} \put(0,-4){\oval(4,10)[b]} \end{picture}

yet another test:

• Failed to rasterize \begin{picture}(0,0) \put(0,0){\circle{24}} \put(-4,3){\circle{4}} \put(4,3){\circle{4}} \put(-3,3){\circle*{2}} \put(3,3){\circle*{2}} \put(0,-1){\oval(12,6)[b]} \put(0,-7){\line(0,1){3}} \put(0,-4){\oval(4,10)[b]} \end{picture}

hope I don’t get banned for too much failed garbage:

• I guess mimetex isn’t really latex

• zzzzzzzzz………..

• ignore me

• Maybe circles are the problem?

• Failed to rasterize \begin{picture}(0,0)(-320,-20) \put(0,0){\oval(24,24)} \put(-4,3){\oval(4,4)} \put(4,3){\oval(4,4)} \put(-3,3){\oval*(2,2)} \put(3,3){\oval*(2,2)} \put(0,-1){\oval(12,6)} \put(0,-7){\line(0,1){3}} \put(0,-4){\oval(4,10)} \end{picture}
