There's a sci-fi book I read a while back that had as a plot point an alien species that had algorithmically optimized its decision-making processes so much that it was no longer recognizably conscious. I think about that now and again when I get a little too invested in some system or practice.
Was it good? Do you have the title?
Completely tangential story. A few months back I was getting an MRI. I stashed my belt, coins, keys, and phone. The machine started its clicking and thumping when I realized I had my wedding band on my ring finger. Immediately my mind raced to a video I once saw of an MRI machine propelling a fire extinguisher across the room. I braced for my finger to be torn off while I slowly took the wedding band off using only o…
Even non-ferromagnetic materials react to the high field strength, and to show that, they let me hold a ring of aluminum just outside the bore. You can feel it "snap" to either parallel or perpendicular to the table when you try to turn it. It was a surreal experience.

I've never heard this before! When I started flying it was just the 2 mono jacks that you still see on planes that haven't been updated (always wondered why it wasn't just a stereo jack) Pretty surprising to hear there's air/sound tubes rigged on to every seat on a plane. Seems like the sound tubes ended in the 70's: https://apex.aero/articles/sound-tube-surprising-history-air...

What was your experience with the MRI like? Specifically, did you "feel" it? I've had my knee scanned for ACL damage, and have spoken to a few other acquaintances that have had scans as well. We've all discussed having some sensation in the exact part of the body being scanned. We all just happened to similar sports based knee injuries. It was just the slightest of tingling, but noticeable. Definitely not painful or…
I have had an abdomen MRI. I definitely felt sensations when the machine was doing particular sets of scans. Also, I accidentally left my wedding ring on (I informed them, they were not interested in the slightest). My right felt hot during the scans. Not painful burning hot, but warmer than body temp for sure.

MRI can cause a tingling sensation. Apparently, it can be quite noticeable when you make a loop, e.g. with your arms. See peripheral nerve stimulation.
So they work like a stethoscope. Would they sound better if they used a liquid instead of air for the conduction?
Probably not, recall how sounds sound underwater, they do not sound like they do above it.

Twelve channels of the weirdest and/or lamest music you'd ever heard in your life, all in a faint, tinny form that makes AM radio sound audiophile quality.
