The Strangeness Correction About Murray Gell-Mann

This strangeness correction appeared in today’s New York Times:

OBITUARIES

An obituary on May 25 about the physicist Murray Gell-Mann overstated a law about the conservation of a quantity in physics called strangeness. It is conserved in strong interactions and electromagnetic interactions but not in weak interactions. It is not the case that “like energy, strangeness must always be conserved.”

(Thanks to noted New York attorney William J. Maloney for bringing this to our attention.)
