Those are, again, 1945 weapons.

Those are based on the process of fission.

Fission is when a nucleus of an atom splits...

And basically one element, we all know elements like hydrogen and oxygen and carbon and so on, but an element like uranium or plutonium splits and produces two other elements.

And

energy is produced in such a reaction.

And, you know, a tiny amount of energy is produced in one reaction.

But when you have many, many, many reactions, you can have a lot of energy.

Another process is called the process of fusion.

And that's when actually nuclei of two elements come together and produce energy that way.

So, for example, two hydrogen nuclei come together to form here.

Helium and energy is produced that way.

That process actually takes place in the sun.

That's how the sun produces its energy.

So fusion is a good thing.

We quite simply wouldn't have life on this planet if it weren't for fusion.

But again, using fusion for the purpose of weapons is a whole other thing.

So depending on what you do, and here's the interesting thing about fusion or hydrogen bombs.

in order to actually bring so,

You know that, so if I have hydrogen nuclei, so this is, let's just step one second to just remember what an atom is, what elements are.
