"So when two heat engines each with a--"

"There's no magic anywhere!"

Sandra wrapped her hands over her head and let the frizzy tresses tickle inside her elbow pits. The mousey haired human was having trouble but not with the contents of the physics textbook spread out in front of her, rather with what it implied.

"Why do you say that, Sandra?" a bespectacled young man in entirely too formal clothing spoke over his own pile of physics and lecture notes.

"Everything magic has something to do with turning around this entropy thing," Sandra moaned, pointing down at the book perhaps a bit too dramatically. "And they've been telling us for the last three chapters that reversing entropy is 100% impossible."

"What brought up magic? I thought we were studying Phys--"

"Physics, bah." she closed her thick textbook with a thump, "We've been studying it for hours and where has it got us?"

"We're the only ones in this class whose grades aren't hurting. Besides that weird Eugene character."

"I mean, what's the point? Passing this class won't affect the eventual outcome. Microstates are indeterminate, but the macrostate is easily predictable." She stared across almost accusingly at the unexpressive boy, as if daring him to respond.

"Butterfly effect," he said. "A microstate can have a large effect in the future, so even the macrostate is not predictable. Look, let's just try to get these equations down..."

"I'm done, Andrew." Sandra said, pushing the bangs out of her eyes and standing up. "I'm just... done." She walked off then perhaps a bit too quickly.

She made it as far as the outside of the building while Andrew sat watching her leave, before her stomach tightened with hunger. "How long were we..." she mused, checking a slim wristwatch and grimacing. "2 hours, great. It's the dinner hour." Sandra turned around and stalked right back into the building she had left from, because in letters above the window it was clearly marked "Cafeteria"

Ten minutes later Sandra and a tray clattered down across from Andrew, the girl sitting resolutely and chewing on her bread roll in silence. "When a particle accelerator..." Andrew started cautiously. Getting no response, he continued, "When a particle accelerator accelerates protons to near light speeds, then collides them together in massive collisions greater than either particle themselves would possess...
