# Physics Valentines (And Anti-Valentines), For Those You Love (And Hate)

The staff of symmetry has created a fun set of physics-themed Valentines to share with the people you love. And because ours is a universe that contains both matter and antimatter, they've created a complementary set of anti-Valentines, for the people you love to hate.

My favorite Valentine/anti-Valentine pair appears above. The cards are designed for those who "seek to rekindle (or extinguish) a romance with someone intrigued by the invisible elements of the cosmos, such as the yet-to-be-discovered dark matter." The cards come in a few other flavors, including neutrino, LHC, and Max Planck. Check out the full lineup – which you can print for yourself – over at symmetry.

OK, it's a math love poem, not a physics one, but I can't resist quoting from Stanislaw Lem's "The Cyberiad" (brilliant translation by Michael Kandel):

Come, let us hasten to a higher plane,
Their indices bedecked from one to n,
Commingled in an endless Markov chain!

Come, every frustum longs to be a cone,
And every vector dreams of matrices.
Hark to the gentle gradient of the breeze:
It whispers of a more ergodic zone.

In Riemann, Hilbert or in Banach space
Let superscripts and subscripts go their ways.
Our asymptotes no longer out of phase,
We shall encounter, counting, face to face.

Thou’lt tell me all the constants of thy love;
And so we two shall all love’s lemmas prove,
And in our bound partition never part.

For what did Cauchy know, or Christoffel,
Or Fourier, or any Boole or Euler,
Wielding their compasses, their pens and rulers,
Of thy supernal sinusoidal spell?

Cancel me not–for what then shall remain?
Abscissas, some mantissas, modules, modes,
A root or two, a torus and a node:
The inverse of my verse, a null domain.

Ellipse of bliss, converge, O lips divine!
The product of our scalars is defined!
Cyberiad draws nigh, and the skew mind
Cuts capers like a happy haversine.

I see the eigenvalue in thy eye,
I hear the tender tensor in thy sigh.
Bernoulli would have been content to die,
Had he but known such a2 cos 2ϕ!
