Why the Atomic Bomb Is So Powerful - Feynman Explains the Science
The Physics According to Feynman

Why the Atomic Bomb Is So Powerful is explained through the science of nuclear fission, chain reactions, and Einstein’s famous equation. In this video, physicist Richard Feynman breaks down the physics behind the atomic bomb and reveals how a tiny amount of matter can release unimaginable energy.
Why the Atomic Bomb Is So Powerful becomes clear when you understand the hidden energy inside the atomic nucleus. This video explores the Manhattan Project, nuclear chain reactions, uranium-235 fission, and the physics that allows atoms to release energy equal to tens of thousands of tons of explosives. From neutron collisions to Einstein’s E = mc², the science behind nuclear weapons reveals how microscopic particles can unleash forces capable of transforming entire cities.
You will learn how nuclear fission works, why chain reactions grow exponentially, and why nuclear explosions release energy millions of times greater than chemical explosives.

For the 3P + 1P we have 9 + 1 = 10 neutrons, so that means we have 16-10= 6 neutrons to use as atomic energy
For the 2P + 2P we have 4 + 4 = 8 neutrons, so that means we have 16 - 8 = 8 neutrons to use as atomic energy
For the 1P + 1P + 1P+1P, we have 1+1+1 + 1 = 4 neutrons, so that means we have 16-4=12 neutrons to use as atomic energy. Assuming 10 kilogram force per neutron, then we can have and explosoion of 120 kilograms from separating 10 neutrons from the original atom.
There are approximately 3 * 10 ^26 neutrons in one kilogram of Uranium-235.
Neutrons per Atom: Uranium-235 has an atomic number of 92 (protons) and a mass number of 235. So 143 neutrons per atom.
At my young age, this used to show that if one splits an atom, one needs fewer neutrons to maintain the stability of what remains.
that stays in place and doesn't want to expand its dismissal
with destruction, and heat is the distance coping distruction,
naturally the sudden introduction having a pressure wave
expansion and pressure is heat as well, a absorption
point of heat.
It needs to at least mention the strong nuclear force, and the TWENTY POUNDS of force it exerts between EACH PAIR of atomic nucleons to hold them together! It needs to tell that the 20 pounds released from JUST ONE fissioning uranium atom could be seen by a human as making a grain of sand VISIBLY JUMP. It needs to calculate that 20 pounds per nucleon pair, multiplied by the number of nucleon pairs broken when fissioning a single U-235 atomic nucleus, multiplied by the TRILLIONS UPON TRILLIONS of atoms in a kilogram of U-235, multiplied by the number of kilograms in an atomic bomb, multiplied by the fraction of atoms in the bomb that actually undergo fission, balloons into a TRULY COLOSSAL number of pounds of force.
It also needs to at least mention HOW all that force got inside U-235 atoms in the first place! It needs to tell that EVERY SINGLE ONE of those U-235 atoms were created MILLIONS or BILLIONS of years ago by EXTRAORDINARILY VIOLENT high-energy astrophysical events like supernova explosions and neutron star mergers. It needs to describe how part of the GIGANTIC forces from those events was fused into COUNTLESS TINY ATOMS, where it has remained in opposing balance for many MILLIONS or BILLIONS of years since.
It needs to do at least that, plus more, all in the radically simple and humorous Feynman style to which we YouTubers have so recently become accustomed. It did not, earning my thumb down.
The mass 2 kg uranium multiply by (360,000)power of 2
Not per second .. divide by millisecond
Grows huge number
