MWI: Probability

I’ve come to realize that, when it comes to the Many Worlds Interpretation (MWI) of quantum physics, there is at least one aspect of it that’s poorly understood. Since it’s an aspect that even proponents of MWI recognize as an issue, I thought I’d take a stab at explaining it. (If nothing else, I’ll have a long reply I can link to in the future.)

The issue in question involves what MWI does to probability. Essentially, our view of rare events — improbable events — is that they happen rarely, as we’d expect. Flip a fair coin 100 times; we expect to get heads roughly 50% of the time.

But under MWI, someone always gets 100 heads in a row.

Upload

A week ago Sunday I stayed up late binging Solar Opposites. This Sunday I stayed up to 4:00 AM binging Upload, a new comedy from Greg Daniels (just released on Amazon Prime). In both cases, my intent was to check out just an episode or two, but in both cases I couldn’t stop watching.

Solar Opposites was more like a fun party I didn’t want to leave (I’m a night owl, anyway). Upload, likewise, was a delight I didn’t want to end, but I was also seriously sucked into a really good story. I am very much anticipating season two.

I don’t hand out Wow! ratings lightly but Upload just might rate one.

Complexity and Randomness

Last week, when I posted about the Mathematical Universe Hypothesis (MUH), I noted that it has the same problem as the Block Universe Hypothesis (BUH): It needs to account for its apparent out-of-the-box complexity. In his book, Tegmark raises the issue, but doesn’t put it to bed.

He invokes the notion of Kolmogorov complexity, which, in a very general sense, is like comparing things based on the size of their ZIP file. It’s essentially a measure of the size of information content. Unfortunately, his examples raised my eyebrows a little.

Today I thought I’d explore why. (Turns out I’m glad I did.)

Spiders

I have no illusions about being a writer. As with many people, I like to express myself, so I write about the things I think and talk about. I suspect the handful of readers who know me in real life find these posts similar to our conversations. (Some posts have come from those conversations.)

Fiction, let alone poetry, are skills a bit beyond my ken, but every once in a while something pops out of my brain. Seems some thoughts don’t work as well dressed in basic prose (although you’d think it goes with everything).

This has been sitting in my Drafts folder since August 2012, and given that it’s spring and I’m cleaning out the backlog, it’s definitely time to get rid of the…

Spiders

I share my world with spiders;
I like the wee beasties.
They live their little lives,
While I live mine. (A giant among them.)
I regard their predatory nature.
Tiny hunters, fierce and fatal.
Small solitary watchers;
Do they, in turn, regard the giant?
Do they tell stories to their young:
‘Ware the giant! Stay off the white walls!
Do not draw the giant’s eye,
Least the tissue come whisk you away.

I’m a computer programmer by career and hobby, so I have a natural affinity for things that come in packages of eight. I also love that they eat other bugs, especially the occasional ant.

And Spiderman always was one of my favorite Marvel heroes. (Come to think of it, he may, in fact, be the top fave.)

Stay friendly to spiders, my friends!


Interactive Boloney

I was planning on curling up on the couch with some good reading material today, but I bumped into something in my news feed this morning that raised my blood pressure and gave me the perfect excuse to get rid of another old note and vent some spleen (I like to keep it aired out).

The bitter irony is that what I see as a problem just doubled. It used to involve just one episode of a TV series I really like. Now it involves another episode of another TV series I like. Two episodes I will never, ever touch. If they were the last TV episodes in the world, I’d stop watching TV.

I’m talking about Netflix and their @#$%ing interactive videos.

Solar Opposites

Sunday I binged through all eight episodes of Solar Opposites, a new cartoon from Justin Roiland and Mike McMahan. It was originally created for Fox but shelved. Now it’s on Hulu, released just last Friday (May 8).

Roiland is well known to Rick and Morty fans as, not only half the creative team (along with Dan Harmon), but as many of the voices, in particular both of the titular main characters. (Apparently considerable drinking and ad-libbing goes on during voice recording.) In Solar Opposites, Roiland restricts himself to just one main character.

If you like Rick and Morty, you’ll probably like Solar Opposites.

Cool Elmore Leonard

For this Mystery Monday I want to tell you about a great American writer whose name you might not know: Elmore Leonard (1925–2013). As with Philip K. Dick, another great American writer, it’s quite possible you’ve seen a movie based on his work without realizing it. In fact, Elmore Leonard gives Stephen King a run for the money when it comes to works adapted to film.

Two of my very favorite films, Get Shorty (1995) and Jackie Brown (1997), are adaptations of Leonard’s novels. The former is the second film that restarted John Travolta’s career, and many believe the success of the film greatly depends on the source material (I quite agree).

If you like crime fiction, you definitely want to get into Elmore Leonard.

Parker: Humble Pi

I just finished Humble Pi (2019), by Matt Parker, and I absolutely loved it. Parker, a former high school maths teacher, now a maths popularizer, has an easy breezy style dotted with wry jokes and good humor. I read three-quarters of the book in one sitting because I couldn’t stop (just one more chapter, then I’ll go to bed).

It’s a book about mathematical mistakes, some funny, some literally deadly. It’s also about how we need to be better at numbers and careful how we use them. Most importantly, it’s about how mathematics is so deeply embedded in modern life.

It’s my third maths book in a month and the only one I thoroughly enjoyed.

Tegmark: MUH? Meh!

I finally finished Our Mathematical Universe (2014) by Max Tegmark. It took me a while — only two days left on the 21-day library loan. I often had to put it down to clear my mind and give my neck a rest. (The book invoked a lot of headshaking. It gave me a very bad case of the Yeah, buts.)

I debated whether to post this for Sci-Fi Saturday or for more metaphysical Sabbath Sunday. I tend to think either would be appropriate to the subject matter. Given how many science fiction references Tegmark makes in the book, I’m going with Saturday.

The hard part is going to be keeping this post a reasonable length.

BB #67: Friday Bubbles

I’ve been on something of a mission to crank out posts in an effort to reduce my backlog of drafts and notes. (What’s discouraging is that I just found a pile of notes I’d tucked away and forgotten about. With any luck, most of those ideas will have aged out, and I can trash them.)

Since it’s Friday, I thought I’d burn off a bunch of small ones in a Brain Bubble post. As usual, these are small seeds that never grew into a full post, but I hate to just toss the seedlings.

Today’s theme: Things that annoy me, but only slightly.
