Last week I read Quarantine (Greg Egan, 1992), a science fiction novel that explores one of the more vexing conundrums in basic physics: the measurement problem. Egan’s stories (novels and shorts) often explore some specific aspect of physics (sometimes by positing a counterfactual reality, as in the Orthogonal series).
In Quarantine, Egan posits that the human mind, due to a specific set of neural pathways, is the only thing in reality that collapses the wave-function, the only thing that truly measures anything. All matter, until observed by a mind, exists in quantum superposition.
Unfortunately, it’s difficult to explore how this ties into the plot without spoiling it, so I’ll have to tread lightly.
There is a saying: “The best thing since sliced bread!” That seems a low bar, but sliced or not (and despite the danger), I’m a huge fan of bread. I always have been. Fresh out of the oven can’t be beat, but toasted takes a close second place in my book. Toasting can make mediocre bread tasty and good bread divine.
As such, my standard breakfast for decades has been two slices of toast. (With the occasional substitution of a toasted bagel.) And I’ve noticed that a loaf of sliced bread always seems to have an even number of slices — which works out perfectly for those who make sandwiches as well as for anyone like me with my two-slice breakfast.
So imagine my surprise, today, when a single slice was left!
I have always liked those comparisons that try to illustrate the very tiny by resizing it to more imaginable objects. For instance, one says: if an orange were as big as the Earth, then the atoms of that orange would be a big as grapes. Another says: if an atom were as big as the galaxy, then the Planck Length would be the size of a tree.
The question I have with these is: How accurate are these comparisons? Can I trust them to provide any real sense of the scale involved? If I imagine an Earth made of grapes am I also imagining a orange and its atoms?
So I did a little math.
Last week I discovered The Highwomen, a musical supergroup comprised of singer-songwriters Brandi Carlile, Natalie Hemby, Maren Morris, and Amanda Shires. They are, for the moment, my new favorites, and today I’m going to just turn the stage over to them:
For Sci-Fi Saturday I thought I’d mention how much I’ve enjoyed some recent Netflix original productions about robots (the very intelligent kind). As usual, I’m a little late to the party. For most people with Netflix, the post’s title probably immediately evoked either or both shows.
I’m speaking, of course, of Love, Death & Robots, an anthology of animated shorts, and of I Am Mother, a movie about a robot raising a child (humanity’s last best hope). I was delighted by the former immediately, but with the latter it wasn’t until I knew the entire story that my opinion changed from poor to good. Through most of the movie it seemed to be a rather flawed story I wasn’t sure I liked.
But the ending put all the plot holes in much better light!
I have a growing list of links to articles that catch my eye, things I’d like to post about (for whatever reason). But there’s a tension between posts based on lists of links or draft posts or idea files versus posts based on what I’m currently thinking about.
I seem to feel the latter isn’t enough, that I need a reserve for “lean times” — which never happen. More and more, I post when something strikes me as worth the effort. The “idea pile” seems almost like homework.
Anyway, here are some things that recently caught my eye.
In the last week or so I read an interesting pair of books: Through Two Doors at Once, by author and journalist Anil Ananthaswamy, and The Order of Time, by theoretical physicist Carlo Rovelli. While I did find them interesting, and I’m not sorry I bought them (as Apple ebooks), I can’t say they added anything to my knowledge or understanding.
I was already familiar with the material Ananthaswamy covers and knew of the experiments he discusses — I’ve been following the topic (the two-slit experiment) since at least the 1970s. It was nice seeing it all in one place. I enjoyed the read and recommend it to anyone with an interest.
I had a little trouble with the Rovelli book, perhaps in part because my intuitions of time are different than his, but also because I found it a bit poetic and hand-wavy.
Robert Mueller appears before Congress tomorrow…
But will it amount to anything in the current political-social climate, is the question. The last few years make that an iffy proposition.
Posted a while back, but even more relevant now:
We ought to be able to run a moldy orange against him and win by a landslide, but parts of this country are in fully embracing their ugly underbelly. It’s feeling like the 1960s again.
