Cheated. I got acid at guess four and tried everything I could think of, I couldn’t think of many five letter words. Was really thinking it was going to be more obscure so I googled it, I’ve heard of fatty acids but it likely would have taken me a loooong time to get there.

Got acid early but couldn’t think of the five letter word. After some time, thought it might be short for something, so I put in short and found a short-*****, so put in chain. Then it came to me

I tried numbers fairly early because of the “from _ to __” in the first paragraph. I never uncovered that, but the numbers led me to notice the chemical formula and I got the answer after uncovering CH3(CH2)nCOOH.
I might have tried “chemistry” near the start, but in my head I’d already tried it because I tried it yesterday, but never finished that redactle. It wasn’t until after the fact that it dawned on me that it was a new puzzle.

I’ve actually been to the campus (I didn’t know it was famous). Got lots of hits for Germany so tried some German cities. Spelled it as Heidelburg at first but thought I’d try it with an “e” (I believe burg means mountain whereas berg is castle and Heidelberg has a famous castle and a mountain/hill) Very obscure entry.
‘University’ strikes again. Was totally lost for a long time, had Germany so once I finally guessed university I knew what it was. Tried all of the names I could think of and had to cheat.
