I think the first time I was on /sci/ was 2008.
Back then I was more on /tv/ at first, but the most time I certainly spent on 2008. Hottest time was 2010 to 2013, when I did my PhD.
Crazy to think there's probably people reading this who weren't born when I was on /sci/ the first time.

Anyway, I think OP's pic is super old.
What's the oldest /sci/ meme, is my qtddtot.
I suppose the oldest thing I remember is Planet of Fire vs Sun of Ice or however it goes.
Not sure if there's memes that originated on /sci/ in particular, and only spread from here.
I think the word "brainlet" is a candidate, but I don't know if I could say more than that.
There was the "/sci/ was never good" saying, but I haven't seen it in a while. But I'm only coming by every two month or so, in the last years.

/sci/ topics come in epochs. I think whatever I learned atm notably influenced /sci/ hot topics. From quantum field theory, category theory, type theory, set theory. Set theory is lasting for a while now - regularly when I come by I see people debating. I think people got a bit smarter on math. Maybe because people are getting older.

It must be a decade now or more, but I remember a time when posting didn't require a fucking annoying captcha.

Anyway.
What are some memes originating from /sci/?
