Thank you for your suggestions! This will definitely cut down on time. I have implemented some of the commands from Ben Niehoff's preamble, and created some on my own. Also, looking at arxiv sources is my go-to place now if I come across something new.
I was wondering if you guys could suggest some macro-s that you use in your LaTeX preamble, to speed up typing up your homeworks/reports.
I think typesetting any report looks very professional, so I don't want to stop LaTeX-ing them. However, it does take a huge chunk of my day...
Thank you for your response and for sharing this link! Forgive me for my silly question, I have just started learning about this subject. But I think I have a better idea about it now. I will be reading more about the connection of particle physics and cosmology. Very interesting.
