Rodney McKay returns to Earth to visit his sister, Jeannie Milller, after she solves a mathematical proof that may provide for a means for transferring particles to a parallel universe. They need her help to further determine the practical aspects of her theory but she refuses to sign a non-disclosure agreement. She quite surprised to see Rodney on her doorstep given that he has not been in touch with her for four years. He manages to convince Jeannie to cooperate by transporting her to the Daedalus and soon they are in Atlantis working on the problem. There is more than just a little sibling rivalry between the two and she regales everyone with tales from Rodney's youth, not the least of which is that Rodney is his middle, not his first, name. Their attempt at transporting particles to a parallel universe goes somewhat awry when Rodney's doppleganger suddenly appears.

"That is North America and you are in geosynchronous orbit," says Carter while pointing out the window, All geostationary orbits are on the equator though and at an altitude of roughly 35,800 kilometers. You cannot therefore not be above North America in a geostationary orbit and you always see a complete Earth hemisphere at that distance. Earth would appear a lot smaller. See more »

best sci-fi episode ever
13 April 2014 | by (United States) – See all my reviews

This is one of those "ultimate classic" sci-fi episodes of all times, the likes of which one is lucky to see once a decade. Brilliant story, absolutely hilarious, heartwarming, totally entertaining, and even a little highly speculative science around the edges.

Stargate Atlantis is one of the best 3 or 4 sci-fi series ever, and this is the best episode.

This is very much a standalone episode that doesn't really require you know much about Stargate Atlantis, though you should have seen at least a few other episodes so you know the characters (especially Rodney McKay).
