For the past two years, the biggest buzzword in the world of science has been "Large Hadron Collider." If anybody wanted to sound smart, they simply spoke the name, and presto: your perceived intelligence doubled. Of course, this illusion could be easily counteracted when asked about the nature, purpose, or any general information regarding about the Large Hadron Collider. Simply put, it's like a game of Taboo. The purple side of the card reads "Large Hadron Collider," and any mention of the words "Big Bang Machine," "Mountains in Switzerland," "Destroy the Earth," "Tiny Particles," or "Giant Metal Racetrack" will result in a loud buzzer blaring in your ear.
It was only a matter of time before The Large Hadron Collider was mentioned on The Big Bang Theory. As particle physicists, Leonard and Sheldon work in the exact field in which the Large Hadron Collider is applicable. Over lunch, Leonard announces the university has selected him to attend a conference in Switzerland, where he will visit the Large Hadron Collider. As a bonus, he gets to bring a guest of his choosing. Upon revelation that the conference will be on February 14th, both Raj and Howard understand LeonardÃ¢â¬â¢s intent to invite girlfriend Penny for a romantic vacation. Sheldon, oblivious as always, disregards the possibility and assumes he will be attending instead.
