But that’s before a Dudette from the future tells them about the Galactic Academy of Science and sends them on a mission back in time to beef up their scientific knowledge. Mae and Clinton meet Dmitri Mendeleev, Niels Bohr, John Bardeen, William Shockley, and Robert Noyce. They break up a séance, escape the Gestapo, jump from a plane, and return with enough understanding of how electronics work that they can tackle the mystery of the Russian scientist and search for the missing diamond chip.
