Unfortunately, no one bothers to remind Leonard that this is the drill.
Leonards colleagues and friends clearly have issues with his flippant accusations that physics is a struggling field.
He balks, offering that the truth is the foundation of the sciences, which Sheldon rebuffs.

Theres just one problem: Leonard doesnt believe it.
And more surprisingly, neither does Sheldon.
After 15 years working together, Leonard finally gets to hear Sheldon say, You were right.
Sadly, its bittersweet, since Leonard may lose his job for speaking his mind.
What are two depressed scientists supposed to do in a time like this?
Why, drink a bottle of bright blue Romulan ale purchased at Comic-Con, of course.
Bernadettes lab throws away test tubes instead of washing them.
Amy naps in a million dollar FMRI machine.
Bernadette has two assistants and doesnt know their names.
Amy works with brains instead of drugs that make your hair itch.
Well, that escalated pretty quickly.
Back at Booze Fest, Penny calls for reinforcements.
She explains to Raj and Howard that science is dead because Leonard killed it.
Raj takes control and reprimands Sheldon and Leonard for acting like two babies.
Now Pennys dealing with four scientists hitting the blue sauce.
This will not do.
She yells at them to buck up because their lives have not been wasted.
They need to get up and get inspired.
Leonard concludes that the only way science can die is if they stop being passionate about it.
