I’ve scrutinized Etsy to find the best science-themed Valentine’s Day cards. By “scrutinize” I mean that I looked at a bunch of them, and only selected the ones that made me laugh. It turns out that I’m far more entertained by physics love jokes than by chemistry or biology ones, probably because I get too critical about the accuracy of those. Like this one, “You are the Na+ to my Cl-“, just seems to say “we don’t really need each other and are not discriminate about who we bond with” to people who know their ions. On the other hand, I know little enough about wave functions to actually find this one funny, even though it probably makes no sense to a physicist:
And another physics card:
I do like some of the biochemistry jokes as well, and actually LOL-ed at this oxytocin card. There’s been so much hype about this molecule, it deserves to be a Valentine’s Day card!
This one‘s a classic biochemistry in-joke. Oh, helicase, you’re so…assertive.
Prefer scientists over molecules? Got you covered!
Of course, nothing says “You’re out of this world” like this laser-engraved wood ornament of Carl Sagan! (I have a lot of thoughts and feelings about this item, and they all came out at once in a giggle-fit. I think that’s a positive review.)
It’s only slightly too late to order any of these items in time for Valentine’s Day, but someone who really loves you won’t care that they get their card a week later. Probably. If you don’t want to risk it, you can always get the pdf version of my favourite set of science Valentine’s Day cards, and instantly download Marie Curie, Nikola Tesla, Stephen Hawking, Ada Lovelace, Alan Turing, Carl Sagan, Werner Heisenberg and Brian Cox.
