The Big Bang Theory

The Expedition Approximation

Series 8 - Episode 6 The Expedition Approximation



So, is Leonard OK with his fiancée Penny being the bigger earner, now that her job in pharmaceutical sales is taking off? That’s the crux of this interesting if laugh-lite episode when the couple make the mistake of visiting the similarly positioned Howard and Bernadette to get their take on financial imbalance.

Raj and Sheldon, meanwhile, have the opportunity to study dark matter in experiments taking place in a salt mine. So they attempt to condition themselves in the university basement. Can the claustrophobic Sheldon sit it out, or will he crack at the mention of funyuns from a vending machine? Rhetorical question, obviously.

It’s been a solid season so far, but fans were sad to hear of the recent death of Carol Ann Susi. Though never seen in the show, her loud Brooklyn bark as Howard’s mother was nevertheless a formidable constant.


Leonard and Penny ask Howard and Bernadette for advice when they argue about money. Meanwhile, Sheldon and Raj try to find out whether they could survive a dark matter research expedition in a salt mine by attempting to simulate the conditions in a steam tunnel beneath the university. Comedy, starring Johnny Galecki, Jim Parsons and Kaley Cuoco.
