"We have to make the politicians understand: this isn’t a new weapon, it’s a new world. I’ll be out there, doing what I can, but you.. you’re an American Prometheus - the man who gave them the power to destroy themselves - and they’ll respect that. Then, the work really begins."

"The power you are about to reveal will forever outlive the Nazis, and the world is not prepared."

"Algebra is like sheet music. The important thing isn't, "can you read music," it's "can you hear it.""

"Quantum physics is not a step forward; it is a new way to understand reality. Einstein's opened the door, [and] now we are seeing a world inside of our world; a world of energy and paradox that not everyone can accept."

"I did what was right for this country. They don’t want me in the Cabinet Room? Maybe they should just invite Oppenheimer instead."

"J. Robert Oppenheimer the martyr. I gave him exactly what he wanted. To be remembered for Trinity. Not Hiroshima, not Nagasaki. He should be thanking me."

"He wanted the glorious insincere guilt of the self-important to wear like a fuckin' crown, and I gave it to him."

"Oppenheimer wanted to own the atomic bomb. He wanted to be the man who moved the Earth. He talks about putting the nuclear genie back in the bottle. Well I'm here to tell you that I know J. Robert Oppenheimer, and if he could do it all over, he'd do it all the same. You know he's never once said that he regrets Hiroshima? He'd do it all over. Why? Because it made him the most important man who ever lived!"

"Amateurs seek the sun. Get eaten. Power stays in the shadows."

"Survival in Washington is about knowing how to get things done."

"[referring to Oppenheimer] A lot of scientists blame me, but how was I supposed to protect him?"

"[referring to the hydrogen bomb] If it could put us ahead again, the President of the United States needs to know about it. And if there’s a possibility that the Russians know about it from a spy at Los Alamos, then we’ve gotta get going."

"[referring to Los Alamos] Robert built that damn place. He was founder, mayor, sheriff all rolled into one."

"You don’t know scientists like I do, counselor. They resent anyone who questions their judgement, especially if you’re not one of them."

"Genius is no guarantee of wisdom."

"You think because you let them tar and feather you that the world will forgive you? They won't."

"[to Oppenheimer, referring to Teller] You shook his fucking hand?!"

"[referring to who is behind Oppenheimer's "security hearing"] Wake up! It is Strauss! It’s always been Strauss, and you know it. Why won’t you fight!?"

"The truly vindictive are as patient as saints."

"[to Oppenheimer] You don’t get to commit the sin, then have us all feel sorry for you that it had consequences."

"You sit there, day after day, letting them pick our lives to pieces. Why won’t you fight?"

"The world is changing. Reforming. This is your moment."

"[to his counsel, Lloyd Garrison] Only a fool or an adolescent presumes to know someone else’s relationship, and you’re neither, Lloyd. Kitty and I, we’re grown-ups. We’ve walked through fire together, and she’ll do fine."

"If atomic weapons are to be added to the arsenals of a warring world, then the day will come when people will curse the name of Los Alamos."

"America and Russia may be likened to two scorpions in a bottle, each capable of killing the other, but only at the risk of his own life."

"Is anyone ever going to tell the truth about what's happening here?"

"Once it’s used, nuclear war, maybe all war, becomes unthinkable."

"Don't underestimate the psychological impact of an atomic explosion. A pillar of fire ten thousand feet tall, deadly neutron effects for a mile in all directions from one single device, dropped from a barely noticeable B-29. The atomic bomb will be a terrible revelation of divine power."

"[to Szilard, referring to the atomic bomb] Just because we’re building it doesn’t mean we get to decide how it’s used."

"We’re theorists. Yes? We imagine a future, and our imaginings horrify us. They won’t fear it until they understand it, and they won’t understand it until they’ve used it. When the world learns the terrible secret of Los Alamos, our work here will ensure a peace mankind has never seen -- a peace based on the kind of international cooperation that Roosevelt always envisaged."

"[to Groves] You didn’t hire me despite my left-wing past, you hired me because of it. So you could control me."

"I don't know if we can be trusted with such a weapon, but I know the Nazis can't."

"[to Lawrence] It’s not your people they’re herding into camps. It’s mine."

"We’re all simple souls, I guess."

"I’m committed to thinking freely about how to improve our world. Why limit yourself to one dogma?"

"[[w:Ernest_Lawrence|[Ernest] Lawrence]], you embrace the revolution in physics, can’t you see it everywhere else? Picasso, Stravinsky, Freud, Marx..."

"Is light made up of particles or waves? Quantum mechanics says it's both. How can it be both? It can't. It's paradoxical, and yet, it works."

"[in response to being asked if he met Werner Heisenberg after leaving Europe] No, not in person no - but you might say that our paths crossed."

"Oh-penheimer, Op-penheimer; whatever way you say it, they know I'm Jewish."

"Members of the security board, the so-called derogatory information in your indictment of me cannot be fully understood except in the context of my life and my work."

"[sees a couple on their phone in a bedroom] Does anyone even fuck anymore?"
