I want to reproduce this equation, but I don't know how to make the highlighted symbol. I checked the Comprehensive LaTeX symbols manual, but couldn't find a similar one.
\documentclass{article}
\usepackage{bbm}
\begin{document}
\[
\mathbbm{I}
\]
\end{document}

I would like to know how to make a point above a symbol (ie : αΊ‹)
I tried \overset{.}{x}, but the point is very small...
Can you help me ?
Thanks
Just to write down one answer, elaborating a bit the source cited in the comments, and to add the following minimal codes.
\documentclass{article}
\begin{document}
$\dot{x}$
$\ddot{x}$
\end{document}
One dot (\dot) and two dots (\ddot) work in math mode as above. Three dots (\dddot) and four dots (\ddddot) the same but they require the package amsmath:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$\dddot{x}$
$\ddddot{x}$
\end{document}
Instead in text mode, the package called stackengine may help:
\documentclass{article}
\usepackage{stackengine}
\begin{document}
\stackon[1pt]{x}{.}
\end{document}
when I want to refer to for example an equation, I do the following:
\begin{align}
R= \frac{c * \Delta T}{2}
\label{eqn:Range}
\end{align}
Now I want to refer to \ref{eqn:Range}.
Then the output is the following:
Now I want to refer to 3.4.
I would like that the output is already:
Now I want to refer to equation 3.4.
Without me having to write equation manually.
The same goes also for tables and figures.
Especially for figures, I would like to know if there are more possibilities to display the reference.
For example with the following:
\begin{figure}[t]
\centering
\includegraphics[width=0.7\textwidth]{Example}
\caption{Example caption}
\label{fig:ExampleRef}
\end{figure}{}
I would like to be able to get also the caption displayed: Figure 1.1: Example caption.
Thank you for your help.
This sounds like a job for the cleveref package:
\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage[noabbrev]{cleveref}
\begin{document}
\begin{align}
R= \frac{c * \Delta T}{2}
\label{eqn:Range}
\end{align}
Now I want to refer to \cref{eqn:Range}.
\begin{figure}[t]
\centering
\includegraphics[width=0.7\textwidth]{example-image-duck}
\caption{Example caption}
\label{fig:ExampleRef}
\end{figure}
\cref{fig:ExampleRef}
\end{document}
I am using the \twocolumn tag to use the two-column layout in LaTeX. The problem is that this does not work properly and the text seems not to be fixed between the borders. Not sure if that minimal example helps, but at least you can see my includes and the text with which it happens.
\documentclass[12pt,a4paper, abstracton]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{amsmath}
\usepackage{amsfonts}

\end{document}
Screenshot of left column in PDF that shows the problem
Why does LaTeX write from the first column into the second column and how can I fix that? I would like to avoid change each line separately, where that happens. I am looking for a global solution.
Since the workarounds of the accepted answer were not satisfactory to me, I kept searching and found a more adequate and fast workaround, adding to my preamble the following:
\setlength{\emergencystretch}{3em}
The length 3em can be changed as needed, just keep it as low as possible in order to preserve optimal appearance.
More details here.
Latex has trouble finding a suitable break point because words with multiple capital letters are normally assumed to be acronyms which should not be hyphenated.
Possible workarounds:
force a line break with \linebreak before the word. This might result in undesirable large spaces in the line, especially in your situation in with only a single white space in the line
tell latex where possible break points are with long\-word (I don't know if there are any possible hyphenation points in NAALADase). This can also be globally for the whole document with \hyphenation{long-word} in your preamble
rephrase the sentence
use another layout. Very short lines combined with very long and unbreakable words is a tough combination

I'm trying to write the big C in the picture below, Could anyone tell me how to write it?. And what is the name of this kind of letters?
With the amsfonts package, you can use the so-called blackboard bold font:
\documentclass{article}
\usepackage{amsfonts}
\begin{document}
\[
\mathbb{C}
\]
\end{document}
I'm trying to use LaTeX with RTL language. when I set columns count to 2, LaTeX use LTR direction as default.
I try to use \RLmulticolcolumns command but it does not work!
\usepackage{multicol}
\begin{document}
\RLmulticolcolumns
\begin{multicols}{2}
some RTL text...
\end{multicols}
\end{document}
Any help?
