The episode 10 of "The Big Bang Theory" Season 7, "The Discovery Dissipation," is scheduled to air on December 05, 2013 as it is Thanksgiving this Thursday. In the upcoming episode, Sheldon will be dealing with the disapproval of his accidental, scientific contribution. And, Howard will have to deal with Raj who comes to stay at his home for a week.

According to the spoilers, Sheldon and Leonard are interviewed by Ira Flatow on NPR. Ira Flatow wants to know from Sheldon how would he feel if he gets a Nobel Prize in Chemistry for his accidental discovery of an element due to a mathematical error, while his original field of expertise is Physics. This is not going to please Sheldon and he will walk out of the studio.

Dr Siebert, president of Caltech, and Sheldon are likely to have a little confrontation. The discovery being incorrect means the University losing out on funds. And, Sheldon does not want to be seen as a "trained monkey" who shows his moves for money.

Will Wheaton will return to help Sheldon deal with his new found fame. Leonard will work on Sheldon's discovery of a heavy metal. He will disapprove Sheldon's discovery. Rather than being happy that the disapproval shifts the focus from him, Sheldon will get mad at Leonard for trying to take away his spotlight. They are expected to again appear on NPR to discuss Leonard's disapproval theory but Sheldon ends up talking about other things.

Raj will stay at Howard and Bernadette's place for a week, as his house is getting fumigated. He is likely become a sore point for Howard. Raj will treat Bernadette much better than Howard. Soon, he is sent packing out of Howard and Bernadette's house, as he is likely to start interring in their marriage.

The next stop for Raj is all set to be Apartment 4A. He will give relationship advice to Sheldon and Amy. And, as a result of that, he will be looking for a new place to stay.
