Episode complete credited cast:


Fifteen year old genius Dennis Kim is a physics doctoral candidate who Gablehauser wants at the college at any cost. Dennis is much like Sheldon was at that age, with the ego and arrogance to match. As such, Sheldon doesn't like Dennis, especially after Dennis criticizes Sheldon's work on string theory, which is his primary research. But Sheldon realizes that one of the comments Dennis makes about his research is indeed true. For Sheldon, this realization means the end of his life as he knows it. Much to his genius friends' chagrin, Sheldon needs to find something academic to do, and who better to do it with than other geniuses (albeit less so than him). So Leonard, Howard and Raj decide that to get Sheldon back to the top of the heap status they need to take Dennis down a few notches by refocusing his fifteen year old mind on more pubescent pursuits.

Sheldon Cooper: Here's the problem with teleportation.
Leonard Hofstadter: Lay it on me.
Sheldon Cooper: Assuming a device could be invented, which would identify the quantum state of matter of an individual in one location and transmit that pattern to a distant location for reassembly, you would not have actually transported the individual; you would have destroyed him in one location and recreated him in another.
Leonard Hofstadter: How about that.
Sheldon Cooper: Personally, I would never use a transporter, because the original Sheldon would have to be ...

The Jerusalem Duality explores Sheldon's weak side in "The Big Bang Theory"
26 April 2008 | by (Baton Rouge, La.) – See all my reviews

Dr. Eric Gablehauser (Mark Harelik) brings 15-year-old Dennis Kim (Austin Lee) to Sheldon and Leonard's attention. He wants Sheldon to welcome him in as a fellow associate. Unfortunately, Sheldon is jealous of him because he accomplished so much at a younger age than when Sheldon was during his teen years (except for when Dennis' family was digging themselves out of Korea). Depressed, Sheldon then busts in on assignments of his friends' which results in the same admonition from Leonard, Howard, and Raj: "Go away!" So those three resolve to get a girl to socialize with Dennis by bringing a bunch of many of them his age to the welcoming party. For a while, he seems uninterested but after Gablehauser introduces him, Dennis comes in and says "no thanks, I'm taking Emma to the mall" as a tall blonde accompanies him. Sheldon than steps in confidently and says, "While Mr. Kim, by virtue of his youth and naiveté, has fallen prey to the inexplicable need for human contact, let me step in and assure you that my research will go on uninterrupted, and that social relationships will continue to baffle and repulse me!" We then see Dennis enjoying kissing Emma under the tree while Leonard, Howard, and Raj look on wondering how he got so lucky when they weren't as fortunate at his age while Sheldon couldn't care less...Another hilarious episode of "The Big Bang Theory" that explores Sheldon's venerability concerning himself no longer being the unique prodigy he once was. We also find out here, with Penny's questioning of why the other three hang with Sheldon who can be so arrogant at times, Howard simply says, "We liked Leonard." Also hilarious was hearing painful dating stories of Leonard and Howard when they were teens. So glad CBS renewed "The Big Bang Theory" for another season. You rock, Chuck Lorre! By the way, Emma Degerstedt had previously appeared on "Samantha Who?" as a teen Sam.
