The program, "Prophets of Science Fiction," airing on the Science Channel
provides three treats. This program was produced in 2006. It airs twice more
before 3 AM EST tomorrow.



At barely 7 minutes into the program, Jules Verne's siting of Florida for
his space gun is presented. A period wooden slide rule is manipulated just
before the equation for escape velocity is worked out. It appeared to be a
model 156 for an unknown maker.



The second showing featured a Bygrave or an Otis King machine at about 53
minutes into the program when discussing H.G. Wells' prediction of an atomic
bomb in about 1915. In fact, Wells coined the very phrase.



There is a third slide rule at 57 minutes. Leo Szilard's idea of a chain
reaction is discussed. In the bottom left hand corner (near his elbow) is a
celluloid slide rule.
