    • Amita: (to Charlie after he rides 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.

    • Larry: Charlie, you’re a mathematician, you’re always looking for the elegant solution. Human behavior is rarely ever elegant.

    • Larry: Here's a discussion: Why is it we remember the past and not the future? Charlie: That's a tough one, Larry.

    • Amita: Actually, I'm spoken for, Mr. Eppes. Back in Madras my parents arranged for marriage to a family friend. A nice Hindu banker from Goa.
      Charlie: Really? Getting married...
      Amita: God no, he's a total ass.

    • Charlie: Sorry, I was busy working on something. I know I'm supposed to be going through some equations for you.
      Larry: Yes, I had wondered if I had gotten the time wrong, or the place, or, uh, quite possibly, the dimension.

    Notes (13)

    • The opening theme came from "Once in a Lifetime" by Talking Heads.

    • The song to which Charlie is listening on his headphones while working on the first equation is "Inertia Creeps" by Massive Attack.

    • When the FBI is checking out all the names of the 50 men in the area, some of the names on the board are members of the crew.

    • While the pilot was being filmed at CalTech, the producers were using some offices in the astronomy building. One of the set designers unplugged a computer that just happened to be the one computer that downloads data from the Hubble Telescope, which took the Hubble offline for about 90 minutes. On the same day, CalTech also got word that one of their physicists won a Nobel Prize, so they were in a good mood and very nice about the computer mishap.

    • In the pilot, Charlie's office is a room at CalTech dressed to look like a professor's office. It was Mick Jackson's idea to hang the little prism in the window.

    Trivia (15)

    • Opening Numb3rs:
      0600 TIME
      594-E4 MAP GRID
      772-04 CASE NUMBER

    • The Math:
      Geographic Profiling
      Probability Theory
      Eleven-dimensional Supergravity Theory
      Projectile Motion

    • The setting in the pilot where they find and kill the rapist is the kitchen of the historic old Ambassador Hotel, just yards away from where Robert Kennedy was shot.

    • This episode has many hints in the background as to the problem of the episode Charlie is focusing on. If you look closely, you'll see several sprinklers in the backgrounds of many scenes.

    • At the beginning of the episode Don is driving a silver Mitsubishi 4-door sedan, license plate number 4Q49902.

    Allusions (4)

    • 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.

    • Charlie (explaining the math to Walt Merrick and other agents): 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"

    • 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.

    • "I don't know Karate but I know Ka-razy."
      Charlie's t-shirt in the final scene has this quotation on the front. It is a misquotation that has made a lot of money for many people. The quotation comes from a lyric in the song "The Payback" on James Brown's 1973 album The Payback. The correct lyric is, "I don't know Karate, but I know Kai Razor." Kai is a brand of straight razors, and hiding razors in a mouth is an old form of fighting, or prison fighting now.
