Number 157 (Story #4), December 23, 1993 by Phillip F. Schewe and Ben Stein CORRECTIONS: A temperature of 250 K is equivalent to -10 F, not +10 F; J.H. (not J.D.) Eberly is at Rochester, not Cornell (Update 156). The 17.6 MeV of surplus energy released in deuterium-tritium fusion is shared between the daughter helium and neutron, and not carried by the neutron alone (Update 155).
