Planck's constant...

...should once again be named "The Elementary Wirkungsquantum." That's what Millikan called it in one of his papers from 1913. The Germans currently call it "Das Plancksche Wirkungsquantum," which is better, but we can't be expected to go about using German for everything.

Next thing you know, we'll be calling the element sodium "Natrium" again. Good times.
