Do You Want to Feel Really Dumb?

I was searching Wikipedia for an indie band named “The Octopus Project” and happened upon two entries: one about the band, the other about some software package called “Octopus”. Intrigued, I clicked on the link. Here is what the description says:

question-markoctopus is a software package for performing Kohn–Sham density functional theory (DFT) and time-dependent density functional theory (TDDFT) calculations.[1]

octopus employs pseudopotentials and real-space numerical grids to propagate the Kohn–Sham orbitals in real time under the influence of time-varying electromagnetic fields. Specific functionality is provided for simulating one, two, and three dimensional systems. octopus can calculate static and dynamic polarizabilities and first hyperpolarizabilities, static magnetic susceptibilitiesabsorption spectra, and perform molecular dynamics simulations with Ehrenfest and Car–Parrinello methods.


Wow, these guys are really smart. What is this, physics? Sure ain’t the E! Channel.
