An attosecond is a LOT shorter than an “in a second”.
Amazing stuff!
An Attosecond is nice, but not as nice as the first attaboy.
Yep! In the old days when you attended a Catholic school run by the nuns, according to my wife when the nun told you to do something and if you responded with "in a second", the attosecond was the amount of time before that ruler cracked you on the shoulder...
Which means the attosecond was well documented back in the 1940's, at least...
