Czech Republic: May 26, 2008 on TV Nova (edit) This episode is rated: TV14-V. (edit) The opening music was "Once in a Lifetime" by Talking Heads. (edit) The original pilot, which never aired, had the events take place at MIT instead of CalTech. (edit) There were two pilots. In the first pilot, Don was played by Gabriel Macht and Alan was played by Len Cariou. The FBI boss had a much larger role and was played by Anna Deveare Smith. The character of Terry was a much smaller role and was played by Jennifer Bransford. Don's partner in the first pilot was a man, played by Michael Rooker. The actors who were in both pilots were David Krumholtz, Peter MacNicol, Alimi Ballard, and Navi Rawat. (edit)

Amita: (To Charlie after him riding an aerodynamic kart with no propulsion) 21.07 seconds, 68.3 miles per hour. No one would ever guess you don't have a driver's license. (edit) Alan: (to Charlie) There's one thing you and your brother have in common, on some things... you're both very thorough. Other stuff... you completely miss. (edit) Charlie: The problem involves finding an origin point from evidence provided by scattered effects.
Larry: Somehow I doubt we're talking about orbital paths and black holes. (edit) Larry: Okay, hooray for making things go faster,but I fail to see how this will provide me the necessary mathematical breakthroughs I need to redefine the fabric of the cosmos. (edit) Larry: Charlie, you’re a mathematician, you’re always looking for the elegant solution. Human behavior is rarely ever elegant.
(edit)

In this episode we learn that Charlie has no driver's license. (edit) Goof:

When they're in the arcade, Larry still has two credits on the game he was playing, and yet he digs quarters out of his pocket, as if he needed to put in more quarters to continue to play. (edit) Goof:

With a winning chance of 1 in 41 million, playing 20 tickets a week, even after 40000 years the chance of winning the lottery at least once would only be around 63.7%, and not a guaranteed win as Charlie seems to indicate with his calculation. (edit) In the original pilot, they are watching a Red Sox game, and Nomar Garciaparra is batting. (edit) In this episode and throughout the first season, the laptop computers used by Charlie and the FBI are Dell Inspirons. (edit)

Larry: Evariste Galois. Brilliant mathematician, not unlike yourself, tackling the hardest problems in his day.

Évariste Galois (1811-1832) was a French mathematician. He made major discoveries in the analysis of polynomials and was the first mathematician to link group theory and field theory, which were until then disconnected mathematical areas. (edit) In the pilot, when Charlie is explaining the math to Walt Merrick and other agents, he says: "Let's do an elementary demonstration". This is part of a quote by Richard Feynman, a late physicist of CalTech, who said: "Let's try an elementary demonstration, and when I say elementary, by no means do I mean elemental" (edit) Charlie: Say I couldn't see the sprinkler...
The sprinkler example was based on an article in Popular Science magazine written by Dr. Kim Rossmo. (edit)
