@whatif.physics3d: What if the smelliest man in history had to invent the shower? Nigel started with a bucket from the river. By the third one he was exhausted, so he built a giant bucket above his head. Then came a valve, a pot full of holes, a fire, a coal plant with a 120-metre chimney… and while digging for more coal, he hit uranium. Splitting one uranium-235 nucleus releases about 200 MeV. Burning one carbon atom gives about 4 eV. That's roughly 50 million times more energy per atom. Which step would you have stopped at? Physics simplified: the split shown (barium + krypton + 3 neutrons) is one of many possible outcomes.
