A wide shot of two small figures walking through a courtyard with large stone buildings. Man: I DON'T GET THE INTEREST IN BIOLOGY. IT'S ALL JUST STAMP-COLLECTING. Woman: THAT'S BECAUSE YOU PHYSICISTS HAVE FAILED. A close-up profile of the woman as she takes a breath. Woman: BIOLOGY IS WHAT PHYSICS WOULD BE LIKE IF YOU'D FOUND A GRAND UNIFIED THEORY. The woman gestures toward the man as they continue walking. Woman: YOU HAVE MULTIPLE NON-OVERLAPPING IDEAS THAT PRODUCE PHYSICAL AND MATHEMATICAL ABSURDITIES. WE HAVE EVOLUTION BY NATURAL SELECTION. A close-up of the woman looking thoughtful. Woman: HAVING LONG SINCE DISCOVERED THE MECHANISM BEHIND EVERYTHING, WE ARE LEFT TO SEARCH FOR THE PARTICULAR WAYS IT PLAYS OUT, IN ORDER TO FIND CONNECTIONS AND SURPRISES THAT REFINE OUR UNDERSTANDING. The man shouts back, looking annoyed. The woman looks gleeful and gestures emphatically. Man: OUR SCIENCE IS HARDER BECAUSE IT'S MORE FUNDAMENTAL! Woman: YOUR SCIENCE IS ALL ABOUT THE BEHAVIOR OF STUFF! OUR SCIENCE IS GOVERNED BY AN ABSTRACT MECHANISM! SUCK ON THAT! A close-up of the man’s face. He has a furrowed brow and a grumpy, determined expression. Man: I KNOW YOU'RE WRONG. I JUST HAVE TO PROVE IT. A shot of the man looking down, deep in thought. Man: PROBABLY WITH MATRICES AND GREEK LETTERS. The woman walks away with a smug smile, holding her coffee. Woman: GOOD LUCK! YOU'LL CATCH UP SOME TIME, BUDDY.
