Valentine’s Day is upon us. If you’re still trying to find the right words to tell the loved ones in your life how you feel, look no further. The staff of Symmetry has assembled another round of valentines so you can let the universal language of physics do the talking. (And if you need more options, you can check out our previous valentines here.)
Love is a mysterious force, and so is dark energy. Tell your valentine how they broaden your horizons:

Show the depths of your unity with this card. Einstein would approve!

Like someone with a magnetic personality? Accelerate your way into their heart with this valentine:

Some particles like neutrinos can be found solo, but not quarks. If a strong force binds you together, let your beloved know:

Of course, the universe is made of matter and antimatter, so you might find yourself in need of an anti-valentine. If that’s the case, let others know about your charged feelings with this message:
