Latex is a stable dispersion (emulsion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well.
Latex as found in nature is a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums that coagulate on exposure to air. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid." It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with separate functions.
The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms and latex clothing.
Originally, the name given to latex by indigenous Equator tribes who cultivated the rubber tree, Hevea brasiliensis, was "caoutchouc", from the words caa ('tear') and ochu ('tree'), because of the way it is collected.
How do I write X bar with the bar over it to denote a vector?
I discovered that if I compose a Latex equation here that I can copy it into a Word file. Is this true of all the symbols? Same for sub and super scripts.
Is there a software tool that I can use to write Latex outside the realm...
I'm hoping someone can help me with the following problem. I have a .p file for generating a .eps file using gnuplot. I want both the y-axis label and the y-axis tics to be formatted using LaTeX. Getting this done is no problem. The problem I am having is that having both of these options...
Hello guys,
I know this topic has been issued many times before. However I have an issue I can't find a solution for.

I'm trying to make a flipbook in the upper right of my thesis. I have already written it using a certain class (this class) and have tried to add the flipbook package.
Latex says it cannot find flipbook.sty (FLIPBOOK) and I think there is some sort of friction with the class I am using.

So, I have this equation:
^{137}_{55}Cs \rightarrow ^{137}_{56}Ba + e^- + \bar{\nu}_e
What I don't like about it is that both 55 and 56 are left aligned and there is a gap between numbers and Ba symbol. I guess I could try to hand align them using spaces and negative spaces, but I also...

Does anyone know how to do box notation in Latex, I've got this:
Li \quad \boxed{\uparrow \downarrow} \quad \boxed{\uparrow\;} \qquad
1s 2s
But I want the quantum states to appear underneath their respective boxes?
\begin{align}
\frac{1}{4} &< (1 - u)^2 + \left(v + \frac{1}{2}\right)^2\notag\\
\frac{1}{4} &< (1 - u)^2 + \left(v - \frac{1}{2}\right)^2\notag
\end{align}
How can I make this on the complex plane with the appropriate area shaded?
u is the real axis and v the imaginary
Hello PF,
I am using MiKTex and TeXnicCenter for writing my Thesis Report. I want to add images (.jpg or .eps format) into the report.

Hello,
I'm just wondering is it possible to put the units of a parameter underneath it rather than next to it. My table is pretty long and I could free up space if I could do this.
For example, let's say I have Velocity (m/s)
I want it to have (m/s) below velocity
I can't figure out how to...
In the past few weeks, I have occasional trouble with my latex expressions (using the itex tag) running over the text that follows them. I also see this in some posts by others. Is there a good way to avoid this? Is it a browser specific problem? ( Mozilla and Firefox are mine.)

I have 2 graphs in latex, side by side, that were attached using:

Hello,
I've recently been asked to submit my assignments using LaTeX and its really time consuming to have to type \begin{math} \end{math} every time I need to switch between English and math symbols.

Is it possible to only show section numbers without chapter numbers in a LaTeX document of class "book"? For instance, Munkres' Topology text breaks things down into chapters but the sections are numbered independent of the chapter. For instance, Sections 1-11 are in Chapter 1, 12-22 in Chapter...

I am sorry guys - I don't have privileges to post in other sections of this forum.
I am looking for a Latex program that shows the result of the code in real time so that I don't have to create a pdf every time I need to see if my code was correct.
Any suggestions?
Thanks.
It's strange no one has noticed but after reading through the Mathjax documentation guide, all you have to do to view the source code is right click over any Mathjax image and click "Show Source". A new window will pop up with the Latex code.
