Either way, thank you and enjoy.

Alright, let's get into this. What are natural units?

In order to understand what natural units are, we want to know what are units.

So, for example, what is a meter?

Or, if you're being Canadian, a meter.

I'm based in Toronto, if that wasn't clear already.

What is a second?

What is a pound?

Now you'll get fairly frenzied if you think about this for quite some time as I have.

That is metaphysically what the heck is a second? What is a meter? What is length?

Science doesn't answer what is questions. It's operational. Science is metaphysically agnostic,

meaning that it doesn't actually make a claim onto ontology. It doesn't tell you what is.

Instead, science gives operational meanings. So, what is a second? It says here, the second is equal to the duration of 9-192-631 periods of the radiation corresponding to the

transition between hyperfine levels of the unperturbed ground state of a sysium atom, a certain isotope of a sysm atom.

Okay, so then the natural question that comes up is why this number?

So why this and not some other number? And the reason is because in London many decades ago,

someone in some back alley took methamphetamine on a Tuesday night and came up with that number.

Now, I'm not kidding. It may as well be that to someone studying high energy physics in the same way that,

well, what the heck is a kilogram? What is a kilogram? It means you go to Paris. You go outside Paris,

actually. So on the borders of Paris, you go to some vault.

And you deal with people being condescending to you because you don't speak French.
