You just need to fine tune your sense of humor to the attosecond beat. Otherwise you miss my punchlines!!
Now, this is important stuff. Everytime we manage a finer division of time, historically, we get a bump up in our paradigm; for example, Da Vinci could not have made his breakthroughs without the ability to measure seconds with some rigour; shortly thereafter, science needed tenths of seconds to work with. Molecular macro-level chemistry measures things in hundredths of seconds, and atomic scale phenomena have been wrassled with at the nanosecond scale for some time now. If you can measure change an order of magnitude tinier, then you can see more of the pattern, obviously. There is also a lot of discussion of "invisible variables" being apossible explanation for discrepancies in quantum physics, implying that there is an order of magnitude of phenomena beyond quantum mechanics that needs to be understood for a complete unified model. The same transition occurred from Newtonian, molecular, atomic, and sub-atomic orders of phenomena. There was always more to be explained, and another order of size to measure in order to find the explanation.
So this attosecond stuff could be the very tip f an iceberg.
I'll just stand by here and wait for Wolfgang to shred my wooly logic all over the map! :>)
