LaTeX What do you use to write formulas here in Physics Forum?

AI Thread Summary
LaTeX remains a relevant tool for typesetting, particularly in academic settings, despite the emergence of alternatives. The MathJax implementation used in web forums has some differences from traditional LaTeX, such as the use of ## for inline tags instead of $. Users have adapted by creating shortcuts with tools like AutoHotKey to streamline their LaTeX writing process, making it as efficient as typing regular text. Additionally, large language models (LLMs) like Bard can assist in converting text to LaTeX, enhancing accessibility for users. Overall, LaTeX continues to be valuable for those engaged in technical writing and academic publishing.

I was here over 10yrs ago, at the time, I use LaTex. You still using that today or there's something new?

I am encouraging my grand daughter to come to this forum as she's going to college soon. I don't want to tell her to learn the wrong thing as it's been over 10yrs already.

Thanks

Alan

LaTeX.
The "LaTeX Guide" is still in the bottom left corner of the reply window.

It is actually MathJax and has some differences from ordinary LaTeX. E.g. we do not have all libraries, hence not all possible symbols, and we cannot add them, and the main difference is that we use ## as inline LaTeX tags instead of $. LaTeX is basically a compiler, and the web-communication needs an interpreter.
 
I tend not to use LaTex, but I really should,

Thanks

I use AutoHotKey and laid a few dozen shortcuts on my keyboard. No accidental Shift Lock anymore, no accidental turning Num Lock off, and yes, many shortcuts for LaTeX. \left. \dfrac{d}{d}\right|_{} or \begin{pmatrix}\end{pmatrix} or \begin{align*}

\end{align*}
are available by Alt+u, Alt+m, and Alt+i. \langle \rangle is Ctrl+y. Just make sure not to overwrite the usual necessities like Ctrl+c or Ctrl+a. I can write Latex almost as fast as ordinary text with my little helpers.

LLMs can easily convert text equations to latex, for example with Bard:

or:
$$\begin{align*}\frac{\partial \rho}{\partial t} + \nabla \cdot (\rho \mathbf{u}) &= 0, \\\rho \frac{\partial \mathbf{u}}{\partial t} + \rho (\mathbf{u} \cdot \nabla) \mathbf{u} &= -\nabla p + \nabla \cdot \mathbf{T} + \rho \mathbf{g},\end{align*}$$

Yes, and especially so in Insights articles.
