The Troublesome Hero Among the Heroes

Chapter 415

The mule’s island is located in Lake Neva to the north of Abyss City, with beautiful scenery, Birds, Speech, Flowers, Fragrances. Relying on the advantages of the local medicine ingredient planting industry and the advanced pharmaceutical industry, the island has vigorously developed the medical tourism industry with the care and support of leaders at all levels for the past 100 years, and has achieved remarkable results.

Lake Neva provides extremely convenient conditions for water transportation in the northern area of Abyss City, but the lake in the north of Abyss City is mostly a cliff of several meters high, and the Ladoga River flows out of Lake Neva Place of Origin The current is so turbulent that you have to go north to get a wharf if you want to take a boat to the island.

Charles and Diana hired a taxi boat moved towards the island, and they both were sitting on the bow chatting at the moment.

"I ask you something." Charles suddenly asked Diana in a low voice, "Do you think you can rub nuclear bombs by hand here in theory?"

Diana extend the hand to touch He touched Charles' forehead, and said, "It's no help, wait for death, and say goodbye."

Charles took Diana's hand off, and Diana took her hand from Charles' paw. Come out, poke his head and say: "You have read too many online novels, and you are still rubbing a nuclear bomb. Like my father, you think that using Transformation Technique to turn Hogwarts gate into uranium 235 can blow it up. Is the mushroom cloud coming out?"

Charles was nodded blankly.

"Are you an expert on the Manhattan Project and an expert on the state-run 221 factory for defrauding funds? Heisenberg failed to master the theory of making atomic bombs until the death of Mustache." Diana looked contemptuously. Watching Charles said, "Even if you pile a lot of uranium 235 or plutonium 239 together and let them exceed the critical value, they will not produce a nuclear explosion, but will cause a chain reaction."

"At that time, what you got was nothing more than a pile of thick slurry exuding high radiation and high temperature. The gap between that thing and the mushroom cloud is greater than the gap between the charcoal ignited during barbecue and the explosion of black powder. It can only rely on The high radiation produces some lethality, and the mushroom cloud is no need to count on."

Charles scratched his head, blushing and said, "So it's like this."

"What do you think. "Diana grabbed Charles' paws, first made his paws clenched his fists, and then squeezed his fingers in order and said: "To create a mushroom cloud, you must first have a lot of neutrons-and fast neutrons- -To make the chain reaction happen in a very short time, how do you plan to get the neutron source? The shelf life of the thing is limited. An important task for maintaining nuclear warheads is to replace the neutron source. The main material, polonium-210, has a half-life of less than five months. "

"Secondly, the neutrons emitted by the neutron source diffuse all around. You have to have a reflective focusing mirror to reflect the scattered neutrons onto the fission material, which can make the chain reaction in It happened in an instant. Do you know how to make this thing? Which element should be processed as much as you know?"

"Third, high-energy explosives are needed to reduce the subcritical fissile material in 1 in 1 million seconds. It was accurately compressed by the explosion in a shorter time. At the beginning, the state-owned 221 factory made thousands of models for this step, and finally selected one of them. In terms of explosive mechanics, how much do you know about the explosives and the composition of the explosives, which can meet the conditions. Do you know how to make detonators?"

"Fourth, do you know how to mine and purify nuclear materials? Can you make other accessories?"

"Fifth, At first, the state-owned 221 factory used an abacus to calculate the data at first. Later, the complex calculations used the newly developed 50,000-speed computer such as the 119 computer of the Chinese Academy of Sciences. I don’t think I can use this level of computer in the short term. Come out."

"I won’t talk about more. Heisenberg didn’t even get a gun-type detonation at the beginning. The first calculation of critical mass was not until he was captured after the war. , Do you think your head is smarter than the Nobel Prize winners in physics?"

"It seems that I think too much." Charles continued sorry, "How do you know this clearly?"

"Nothing." Diana continued to play with Charles' paws. "My best friend—the one who gave me the bag—she learned this. At the beginning, she brag with me, she disappeared from the face of the earth after graduation. "

"disappear from the face of the earth Okay. "Charles nodded his head and said, "I heard that the country has also allocated objects." "

Diana didn't keep up with his thoughts for a while, and was stunned for a while.

Charles said a little discouragedly: "It seems that this road is very difficult to walk." "

"That's not it. "Diana said, "There are more than ten Nobel Prize-winning scientists in the Manhattan Project. There are 1,000 scientists in other industries and 2,000 clerks. "

"Manhattan plans to invest 2 billion US dollars. At that time, the Fletcher class was 10 million, the Essex class was more than 70 million, and the earlier Columnists were about 50 million. "

"Do you think you have so much manpower, material and financial resources to carry out the mission of'brilliant radiation'?" "

"Speaking of which, have you ever counted well? Can your knowledge reserve meet the requirements of ordinary scientific researchers?" "

Charles' face turned black, "believing or not, I will throw you into the water, and then make a mark where you fell into the water, and then catch you up when you get to the shore!" "

Diana narrowed her eyes. "If you have the ability, you can try it?" "

"Forget it. "Charles shook the head, "The water is too cold, it hurts you and I feel bad. "

"Tsk..." Diana gave him a slanted look.

Charles asked at this time: "Then you said last time that the divine force can be condensed into Altria, So it means that the mass-energy formula can work? "

Diana reluctantly shook the head and said, "I didn't use a metaphor you can understand because I didn't take care of you." "

She went on to say: "What do you think is the meaning behind E=mc²?" ”

Then she wrote the derivation of the mass-energy formula in the middle of Charles’ palm while explaining:

The mass point with static mass m₀ passed a time interval under the action of external force F After dt, the mass of the particle becomes m, the mass increment is dm, the velocity is v, the velocity increment is dv, the displacement is dx, the momentum increment is dp, the total energy increment is dE, and the vacuum light velocity is c.

dE=Fdx=(dpdt)dx=vdp=vd(mv)=v(mdv+vdm)=mvdv+v²dm···①

m=m₀√(1-( v²c²))

⇩

m²=m₀²(1-(v²c²))

⇩

m²c²=m₀²c²(c²-v² )

∵cv∴c²-v²≠0

⇩

m²c²(c²-v²)=m₀²c²

⇩

d[m²c²(c²-v²)]dv=d(m₀²c²)dv

∵m₀, c is constant;
