Origin of einstein

Named in honor of Albert Einstein, who explained the photoelectric effect.

From German ein Stein, "one stone", coined by scientists in recent decades, but with tongue-in-cheek tacit acknowledgment of the homonymy with einstein and Einstein; "a pun playing with the famous scientist's name and the German term "ein Stein" for "one stone".

Borrowed from German Einstein. * The common noun is an eponym of Albert Einstein.
