Speaking of Bell tests, I’ve noticed that science writers often struggle to find a good metaphor that illustrates just what’s so weird about the correlation between entangled particles. Bell tests are complex, and because they squat in the middle of quantum weirdness, they’re hard to explain in any classical terms.
I thought I had the beginnings of a good metaphor, at least the classical part. But the quantum part is definitely a challenge. (All the more so because I’m still not entirely clear on the deep details of Bell’s theorem myself.)
Worse, I think my metaphor fails the ping-pong ball test.
I’m torn over today’s topic. I’m tired (for the moment) of nattering about work (got some thanks, but no thanks messages today, and that makes me disinclined to discuss the distress; nepenthe beckons, I’ll answer the call, now 94 bottles of
