I’m sure (P<0.0000003) I would fall for anyone who gave me one of these. The cards above are Valentines from Symmetry, a magazine published by Fermilab and SLAC, two particle-accelerator facilities based in the U.S. My favorite thing about the cards is that, just as there is matter and anti-matter in the universe, each of the Valentines comes matched with an anti-Valentine. So you can express the full range of emotions you need.

Like what you see? There are more cards over on Symmetry‘s website. Symmetry also hosts a PDF you can download and print, so you can give the cards out in person.

P.S. P<0.0000003 is, of course, the statistical certainty needed in physics to say you've discovered a particle.
