Had I heard Albert correctly? Was he proposing that Marcel collaborate with him on the math for an expansion of my theory? “Would I have to do any of the physics?” “No. I will handle the physics, if you manage the math.” Marcel looked at Albert skeptically for a moment, as if he was trying to reconcile the irresponsible college student he’d once known with the successful physicist in front of him. “Please, I need you, Grossman,” Albert begged. Then, very pointedly, he stared at me. “Compared with this problem, the original theory of relativity is childish.”
