Periodic Table of Caltech

₄₆Pd may officially represent Palladium, but on the Periodic Table of Caltech it stands for “Prank Dollars” which are disbursed from an official Techer Prank Fund by a faculty co-conspirator. Likewise, ₃₂Ge (commonly known as Germanium) means Genome in Techer speak—a reminder that Caltech researchers contributed two key inventions to the Human Genome Project.
