Did you know: Fermi equation conundrum
This photograph of Enrico Fermi, Argonne’s founding director, is
a famous one, and appears on the U.S. postage stamp in his honor.
Many physicists have pointed out that there’s an error in the equation
he has written on the blackboard, which appears incompletely on the
stamp. The equation denotes the fine structure constant and should
read:
.
However, Fermi has written it as
.
Physicists have debated this image for many
years. Some think the equation is a mistake. Others, remembering
his famous sense of humor, point to the twinkle in his eyes and believe
he was just having a bit of fun. Either interpretation shows the
humanity of this outstanding scientist, one of the world’s greatest
physicists.
