What do you take it to mean? Neutrons smash into nucleus, releasing neutrons to smash into other nuclei. Criticality, a point of no return, massive explosive force. But this time, the chain reaction doesn't stop.

So here we are, hmm? Lost in your quantum world of probabilities and needing certainty. Can you run the calculations yourself? (chuckles) About the only thing you and I have in common is a disdain for mathematics. Who's working on this in-in Berkeley? Hans Bethe. Well, he'll get to the truth.

This is fantasy. Teller's calculations can't be right. Do them yourself while I go to Princeton. - What for? - To talk to Einstein. Well, there's not much common ground between you two. That's why I should get his view. (birds chirping)

GROVES: Progress? Nice to see you too. Meet the British contingent. Dr. Oppenheimer, Klaus Fuchs. How long have you been British? Since Hitler told me I wasn't German. Uh-huh. Come, welcome to Los Alamos. School's up and running. Bar. Always running. And I thought of a way to reduce support staff.

Well, here we are. Catch me up. What do we know? One of our B-29s over the North Pacific has detected radiation. Do we have the filter papers? There's no doubt what this is. White House says there's a doubt. Wishful thinking, I'm afraid. Are those the long-range detection filter papers?

Now, if we can enrich these amounts, - we need a way to detonate them. - (paper tearing) Are we boring you, Edward? TELLER: A little bit, yes. May I ask why? TELLER: We all entered this room knowing a fission bomb was possible. How 'bout we leave it with something new? Such as? Instead of uranium or plutonium, we use hydrogen. (others murmur and laugh) - TELLER: Heavy hydrogen. - FEYNMAN: Hydrogen. Deuterium. You see? We compact the atoms together under great pressure to induce a fusion reaction.

SERBER: We can now consider the actual mechanics of detonation. ROBERT: Any ideas? SERBER: I call this "shooting." We fire a chunk of fissionable material into a larger sphere with enough force to achieve criticality. What do we think? Anyone? TOLMAN: I've been thinking about implosion. Explosives around the sphere blast inwards, - crushing the material. - (blasting) I'd like to investigate that idea. I'll talk to Ordnance, get you blowing things up.

The biggest man-made explosion in history. Now let's calculate how much more destructive it would have been if it were a nuclear and not a chemical reaction. Expressing power in terms of tons of TNT. But it will be thousands. Well, then kilotons.

Using U-235, - the bomb will need a... - Uh-uh. Sorry. Gadget will need a 33-pound sphere about this size. Or using plutonium, the ten-pound sphere.

Thanks for convening on short notice. I can't believe it.
