Hello, I am beginning rudimentary work on a senior thesis. I am getting tired of hassling with Word to format all my formulas and proofs, and I thought about using proTeXt but I don't want to download 540 mb. My friend told me (a few years ago!) about a program called "Tech," but he might have been referring to LaTeX or proTeXt and I just don't remember; I can't find any program called "Tech." Anyway... Does anyone have any suggestions for a free Windows program that will help me write scientific and mathematical documents? It doesn't need to be that complicated. I just need to be able to write and format words and formulas (mostly PDEs) and insert bitmap images. Any help would be greatly appreciated. If it is really worth downloading proTeXt I'll do it, but I am a bit disgusted by word programs weighing more than 100 mb, even if that space is put to good use... Thank you in advance.
