Yeah.

And your description is exactly right, Chuck.

I wrote that book specifically to say, hey, you could take it in whatever size pieces you want and whatever level you want to go at it.

You're very kind.

Thank you very much.

No, I would say...

If you want to go deeper into the mathematics, because the handy quantum physics answer book and many of the other books about these topics are usually talking about deep concepts and ideas, but those ideas arose from the mathematical and the scientific depths.

of really trying to wrestle with the equations that described how the universe works or the calculations or the measurements that would give us a clue about how the universe works.

So if you want, I'll just mention this.

There is a group called OpenStacks.

S-T-A-X.

And it is free for anyone who wishes.

It's basically a set of textbooks.

These are textbooks that are legitimately for people who want to learn or to major in something or to do, but

It's free on the internet.

And I encourage anybody who wants to look at some of those things to see, like, get a little taste of what an actual textbook looks like and see if you want to go deeper into it.

See if you want to drink deeply of that Stygian spring.

Or if you would rather just have a little knowledge, which, of course, as Alexander Pope says, is a dangerous thing.

Is that it?

To waste or otherwise.
