For today’s Sci-Fi Saturday, we have Juicy Ghosts (2021), the latest novel from mathematician turned science fiction writer Rudy Rucker. The library blurb describes it as “a fast-paced adventure novel, with startling science, engaging dialog — and a happy ending. […] It’s also a redemptive political tale, reacting to the chaos of a contested US presidential election.”
It’s very clear from the text — and explicit in his Afterward — that the novel was inspired by recent American politics. The story features a cruel tyrannical President who, backed by Big Money, steals a third term.
And is taken out by technological wizards. As the blurb said, a happy ending.

Last week I did a little jazz riff on the idea of “story space” — where all the stories live — and how the interesting stories we want to hear are all improbable to the point of having zero chance of actually happening (unless, gasp, statistics can lie).
I thought I’d return to that basic story space idea and, in the process, finally deal with a note that’s been on my idea board for years. My problem has been that, while the idea the note expresses seemed interesting enough, I’ve never quite seen how to turn it into a post. I’m not even sure the idea makes any real sense, let alone is worth trying to write about.
However that’s never stopped me before, and it’s (almost) Chillaxmus, so cue the music, it’s riff time again…

Yesterday I introduced you to the idea of words as numbers. There are many ways to create a map between words and numbers. For example, we could assign them the number that represents their position in the dictionary. That would make words that start with “A” have smaller numbers while words that start with “Z” would have the largest numbers.
There are also ways to treat the words themselves as numbers. We can interpret the letters the same way we do digits. Each letter has an assigned numeric value, and then a string of letters—just like string of digits—forms a number. The scheme I showed you yesterday allows us to treat (only!) single words as numbers.
Now let’s extend this so that entire sentences—or even entire books—become numbers!

Today I’d like to introduce you to a concept I picked up from mathematician Rudy Rucker in his 1987 book, Mind Tools (The Five Levels of Mathematical Reality). I’ll warn you now that there is some math ahead (but no math homework—unless you want to). It won’t get any more complicated than multiplication and addition, but we will be dealing with some extremely large numbers (so large they are more ideas than numbers).
The end result is that we’re going to tie together the written word with numbers. I’m going to show you how every word, every sentence, every book, magazine and blog article can be reduced to a single (very large) number. That we can do this provides a foundation we can use to discover some amazing things about mathematical reality.
It may sound dry or intimidating, but stick with it! You just might find it worthwhile.
