And then, there's 1 more type of complex sentence besides the sentences we get by combining operators, that makes first order logic unique, and these are the quantifiers.

Atomic Mass u

Now, some people call that a theory of everything.

Atomic Mass Unit

Let me write this.

And so I consider myself one of these people, along with most of the other experimental quantum physicists, who need a good deal of logic to string together these complex ideas.

And so the fact that atoms, when you heat them up, only emit light at very specific colors, was one of the key drivers that led to the development of the quantum theory, the theory of the structure of atoms.

Quantum physics balls this out.

Let's break it down.

At the same time, we physicists have been busy trying to make sense of and build on and integrate the discoveries of quantum theory and relativity.

Imagine you could back up a single power station with a single superconducting cable.

It's now under a 10th of a cent.

3. Genetic exceptionalism

The existence of these virtual particles has actually been experimentally confirmed in an indirect sense through a thing called The Casimir Effect and also through some subtle effects of quantum field theory.

And this is essentially the mass of all of the protons plus all of the neutrons.

And so they wrote down all these observations, and they called it the theory of quantum mechanics.

I mean, you might notice that when people care about the mass, when they care about the atomic mass number of an atom, they ignore the electrons.

Atomic weight of carbon.

And we came up with this analogy, and it seemed to work.

The way that silicon behaves, the fact that you can build transistors, is a purely quantum phenomenon.

These are not particles, but they behave like particles.

It would take as many human bodies to make up the sun as there are atoms in each of us.

It's that the relative size so, we have these electrons, which represent very little of the mass of an atom.

In carbon they have this 12.0107.

And that's really the simplest computer.

So, for now, we're gonna sit back down for a second,

So for thinking about the mass of an atom, for all basic purposes, you can ignore the mass of an electron.

The phenomenon you saw here for a brief moment is called quantum levitation and quantum locking.

And each proton has an atomic mass of one, in atomic mass units, and each neutron has an atomic mass of one atomic mass unit.

And one of the astonishing predictions of quantum mechanics, just by looking at the structure of atoms the same theory that describes transistors is that there can be no stars in the universe that have reached the end of their life that are bigger than, quite specifically, 1.4 times the mass of the Sun.

Sir, I want to give you the periodic table, in case you're ever in a bind and need to calculate molecular weight.

Now, that sounds esoteric, and indeed it was an esoteric pursuit, but the quantum theory quickly led to an understanding of the behaviors of electrons in materials
