An attosecond is a LOT shorter than an “in a second”.

Amazing stuff!

Great post! I have been debating what to teach my 10 year old since school is out for the rest of the year! Particle physics is interesting!

Would Heisenberg be OK with this?

The dynamics of electrons change ever so slightly on each interaction with a photon. Physicists at ETH Zurich have now measured such interplay in its arguably purest form—by recording the attosecond-scale time delays associated with one-photon transitions in an unbound electron.

"An attosecond is 1×10 −18 of a second (one quintillionth of a second). For context, an attosecond is to a second what a second is to about 31.71 billion years."

Can any human being really conceive of this time-span?

The researchers measured a delay of up to 12 attoseconds between outgoing s- and d-electrons in helium.

That's some superb measuring.

An attosecond is to a second what a second is to 31.71 billion years.
