And it's a fairly deep book.

It'll take you a while to read, but it'll give you the answer.

And it touches across something called the Gödel Incompleteness Theorem.

And the Gödel Incompleteness Theorem says that in any body of knowledge, there are some things that you cannot prove, that you have to assume.

You have to assume that two is bigger than one.

And that's a really weak one.

And then you end up with things like consciousness, which we can't understand.

And personally for me, quantum physics hurts my brain.

I know it's theoretically possible.

that there's only one electron in the universe and it's everywhere at the same time, it still hurts my brain.

And I still don't fully understand the young double-slit experiment, even though I had some very clever people try to explain it to me.

Maybe I'm a bit slow.

Do you have anything, Nikki, that you have difficulty in understanding?

Pardon?

Are there any things that you have difficulty in making sense of in the world around us?

Oh, I just would love to.

Well, Alastair Reynolds in his science fiction books, which are sort of like space opera, dealing with humans moving across space over generations or thousands of generations, at some stage he postulates humans who have two things buried in their brain, a memory chip that has all of the knowledge of the human race, like the Encyclopedia Britannica or all my books, and secondly, a quantum computer.

I wouldn't mind having both of those in my brain, providing I was still human and not subject to my evil AI overlords.

Because gravity sucks.

So if you get a pyramid, like the one at Cheops, I don't know how high is it, a couple of hundred metres, hundred metres, you've got a thing with four points at the bottom and one point up.
