Chemistry nerds unite! This meme brilliantly showcases the evolution of chemical nomenclature from simple to mind-blowingly complex. Starting with acetylene (C₂H₂), then using its fancier IUPAC name ethyne, then cycloethene (which is actually benzene), and finally the absolutely ridiculous "bicyclo[0.0.0]ethane" which isn't even a real compound! It's like watching your brain ascend to chemical enlightenment with each increasingly pretentious name for essentially the same thing. The expanding brain format perfectly captures that feeling when you deliberately use the most complicated terminology possible just to flex your chemistry knowledge in lab reports. We've all been there, frantically googling "impressive-sounding chemical terms" five minutes before a presentation!
