Physics papers are written in LaTeX: video by Angela Collier, https://www.youtube.com/watch?v=KhWwuQ7qf5A I doubt anyone here doesn't already know all this, but it's a good explainer of why researchers in mathematics/physics/theoretical computer science/linguistics etc. almost universally prefer LaTeX to Word, how the two differ, and why you can infer that a paper in Word was probably not written by a professional. Also with an entertaining rant about why Word is bad, how it's getting both worse and more expensive, and why you should not pay for it.
