Yorel.

So no matter how many times I listen to this, and on what device, all I can ever hear is “Yanny”. I even fiddled around with the equalizer; still only Yannies. It’s only on the “extreme” edits, i.e. when people delete the entire upper tone range, that the Laurel emerges.

Interestingly, I played this for my husband, who is deaf enough to wear hearing aids, and has particular difficulty with high tones, and he apparently hears… a weird combination of both words. So go figure, I guess.

The Kilogram is getting lighter.

Not, like, “the kilogram” as in the unit of weight. But rather The Kilogram, i.e the physical object on which that unit is based.

Incidentally, Americans, the fact that metric units are based on internationally standardized and scientifically determined physical objects is the reason the rest of the world—and everyone in STEM fields—uses it instead of the Imperial system.1 Even Celsius falls under this, since a single “degree” in Celsius represents the same difference in temperature as a single degree in Kelvin—as opposed to a single degree in Fahrenheit, which is its own thing—just with the number labels jiggled around to make it more comprehensible to humans (an average “nice warm day” is approaching 300K).

The more you know, etc.

  1. It’s actually not even that: the US “Imperial” system is actually its own system that’s both, a) different to the original English Imperial system, and b) is used by literally no one else in the world. Oh, and it’s defined based on overly complex conversion formulae from SI units anyway. Go figure.

Good cop, good cop.

It’s long been an anecdotal truism for people who work in interrogation-related fields—from policing to intelligence—that rapport-building techniques work much better for extracting information than verbal or physical coercion. The problem was the science wasn’t behind them, mostly due to the difficulty of studying a field where most of the evidence is classified.

Well. A pair of researches have overcome that obstacle, and been able to empirically assert what’s long been suspected: torture doesn’t work. And, specifically, it doesn’t work when compared to other, less confrontational, techniques.

Stephen Hawking’s voice.

Great article from 2015. My favorite anecdote is where it implies Hawking wasn’t able to use an EEG cap for brain-to-device input because he thought too hard about everything for the system to pick up on one specific something.
