"Figuring out who is a psychopath is not a matter of checking off items on a list while you sit at a bar, hating your boss, husband, or girlfriend (or president). It’s also not a matter of sniffing the air around someone or looking at his or her physical features or Twitter feed."

There are 3 balls: two small ones, one purple and one orange, and one large one, also orange.
One of them is different. Which one?

As one comment mentioned, there is research using other atoms (notably, Yb) that offer even higher precision.  But in some respects it's almost too precise.  Those clocks are so sensitive that even nearby variations in earth density have an effect on clock synchronization due to relativistic time dilation while still at rest.

There are applications for that, but not as many as there are for the relatively (heh) stabler caesium references.

I just saw Jurassic World and kept thinking about this video.
Observation: The dinosaur was always called "she" until they realized she's not killing for food. That was the first time they called her "it." She ain't no anthropomorphic no more.

On the abstraction of words and their corresponding ideas

#cognition   #linguistics   #psycholinguistics  
Whether or not they involve genuine abstraction, words offer a way to reason and communicate — a respite from the tyranny of the specific, says commentator Tania Lombrozo.

A mere mortal who is trying to explore the world we are in and has a special interest in it. I believe it is a duty of mine to try and recognize the troubles in this world and help fixing them, with the definite understanding that the absence of trouble is a matter of absolute improbability.
