During my Masters, and then later during my PhD, I learned how to use the typesetting software LaTeX in order to write my dissertation and thesis. If you ever looked at a maths or sciencey thesis and thought, “How did they do all the equations and stuff?” the answer is LaTeX. At times, writing up was tough; not because the subject matter was difficult or because I was learning LaTeX as I went, but because we were given 20Mb of storage to cover all of our data requirements at the university. Stop for a second and think about the capacity of the SD card in your phone. 20Mb was a microscopic amount of storage to process images, files and so on to produce a dissertation.
