shorter and shorter time scales enable further probing inside atoms

“Krausz thinks that the technique could soon be refined to track events a few tens of attoseconds apart, telling physicists how electrons rearrange themselves inside an atom when they move between different orbits.”

“ Every time we get shorter pulses, chemists say that we don't really need them," says David Klug, a photochemist at Imperial College, London. "But then they find a way to use them. Once it becomes convenient, people will find applications for it." ”
