OT - atomic clock accuracy

[Brian Gaff]

I think the answer to that is it depends on what you are measuring. If yu are looking at things at a tiny level you obviously often deal with ridiculously tiny amounts of time.

There you are then, if it really was the definitive standard they would have rounded it up to 10000000000 and called it a New Second ;-)

Can it? If the quantum levels within an atom changed wouldn't the energy required to hop between them also change and as the quantum amounts are supposed to be fixed...
