What's with all the Stamps?
Our simulation code, OOPSE, has a number of group jokes embedded in the code. Here are a few of the obscure ones:
  • There are a lot of potatoes in the IO code.

  • Some of our code comments come directly from Space Balls.

  • In addition to his love of linked lists, Matt Meineke (the first student who worked on OOPSE) really liked the word Stamp.

Ludwig Boltzmann
Ludwig Boltzmann
One of the founders of Statistical Mechanics. Boltzmann is famous for connecting a thermodynamic quantity (the Entropy) to the total number of microstates for system energy levels that can be occupied. The famous equation that makes this connection,
S = k ln W,
is carved on Boltzmann's tombstone in Vienna.
Joseph Louis Lagrange
Joseph Louis Lagrange
The mathematician who gave us the fundamental principle of classical mechanics, the principle of least action. He's particularly important to our group because of his work on the dynamics of rigid bodies.
William Rowan Hamilton
William Rowan Hamilton

Quaternions
Hamilton's equations are a re-casting of the principle of least action into a form which uses first order partial differential equations. Hamilton's ideas also included a function which is the sum of kinetic and potential terms (the Hamiltonian) which has become the fundamental operator in quantum mechanics. He also came up with the wonderful quaternion scheme pictured in these Irish stamps.
Josiah Willard Gibbs
J. Willard Gibbs
Although the line drawing in the background is actually Maxwell's work, Gibbs is a giant in American science. Our work on water and ice involves thermodynamic integration, and we construct phase diagrams using the Gibbs-Helmholtz equation.
Johannes Diderik van der Waals
Johannes Diderik van der Waals
Primarily known for his work on the equation of state for gases and liquids (plastered across his forehead in this stamp), we know him best for his work on intermolecular attractions and dispersion forces. Besides electrostatic interactions, dispersion forces are the main energy function that we simulate in molecular dynamics calculations.
