Eureka: Season 1, Episode 6

1 - 6: Dr. Nobel

Carter must help an aging scientist recover his memory in time to stop a doomsday device from destroying the world. The old scientist, Dr. Thatcher, has not been the same ever since he never won a Nobel Peace Prize for creating the mutually assured destruction device, which would fire a beam of irradiated uranium isotopes at a mirror on the moon and in turn destroy the planet, so Carter uses a hologram to convince Dr. Thatcher that he got a Nobel, and the scientist is no longer senile. Dr. Thatcher attempts to turn off the device, but since Henry had earlier cut a particular wire while attempting to deactivate the device on his own, the countdown to the device firing continues. Unable to stop the device, at the last moment before it fires Carter hits it with his jeep, knocking it out of alignment so that the beam from the machine barely misses the moon.
