Nuclear energy is produced by splitting atoms or by bringing them together.

Atomic nucleus

Draw atomic nuclei

One, two, three, four, five, six.

Look at plutonium, wow, big target, right? But one third of the time it's just going to eat the neutron in thermal fission.

A neutron essentially turns into a proton and it spits out an electron.

And the proton is actually the defining

700 rads per shot. (Laughter)

So the atom is roughly on the scale of an angstrom.

The quarks, these pink things, are the things that make up protons and neutrons that make up the atomic nuclei in your body.

One femtometer.

It happened one, two, three.

But if you've got a teacher that likes to get you on a technicality, this is technically what mitosis is.

You have fissile nuclei. That means this is a nucleus.

By the time temperature drops to a billion degrees, neutrons and protons can combine to form nuclei of helium according to these reactions.

They just have a probability function.

You see these black dots? Those are the stable nuclides and all the other guys are radioactive.

It contains protons, neutrons and electrons.

But a first mental model in your head is at the center of this atom, of this carbon 12 atom, you have this nucleus.

In which case, the nucleus... would be here.

We also all know that atoms are not the end of the story.

One, two, three, four, five, six.

I want you to go back. Now I want you to hit it with a neutron and see if it will fission.

You can also then turn around and go back and take some of the waste that's already been created in our uranium fueled reactors and potentially destroy those long

Think how many discoveries they represent.

Doc, an invisible being that cannot be disintegrated by atomic fission.

And if you move up to fusion, you get another 10,000 times that.

The most stable nucleus is iron, right in the middle of the periodic table.

What you want, you want blue. Thick blue is good.

And I thought, you know, is this the best way to do it?

These are the mass numbers of each of those and they assume two broad peaks of distribution.

And that's where it gets philosophically interesting.

And so by the end of the telophase that's what we're in, the telophase we will have completed mitosis.

Every innocent bystander will be burned to a crisp.

So imagine a ball that is as tall as a two story house.

The atomic radius is the distance from the atomic nucleus to the outmost stable electron orbital in a atom that is at equilibrium.

So we'll take it from first principles. Let's talk a bit about what nuclear fission is.

But that's a good starting point.

And these electrons are jumping around this nucleus.

So that leaves a couple of places like Iran, maybe Venezuela, that you would like to have very close surveillance of anything that goes on with fissile stuff.

and I'm sure that they still show up at some government defense labs or something like that is that you have a nucleus at the center of an atom.

Think atoms in a grapefruit like blueberries in the Earth.

And maybe something that looks like that.

You change the protons, you got a different element.
