Twelve Days of Physics

This morning I received an email from someone called “Grrrl Einstein” today which read:

I am creating a Physics Calendar for the Holiday season, and I am including twelve entities. So far I have:

  1. Newton’s Laws
  2. The Dirac equation/Schrodinger equation
  3. The Clifford Algebra defining the Dirac gamma matrices
  4. E=mc2/Einstein’s equations/postulates and/or some solution of them, such as the Schwarzschild solution
  5. The principle of least action
  6. Maxwell’s equations
  7. E=hv
  8. The Yang-Mills Lagrangian
  9. The Schwinger-Dyson equations or something else related to functional methods
  10. Stokes’ Theorem
  11. Entropy

What would be a good String Theory equation to round it out? Any things I should include/exclude?
