For the First Time Ever, Scientists Watch an Atom’s Electrons Moving in Real Time

Would like to know what wavelength of light they used, since electrons are smaller than visible wavelengths of light.

[Durus]

It suggests a violation of the Heisenberg uncertainty principle.

This principle was mathmatically cast in doubt some time ago. Logically it doesn't make much sense.

Would like to know what wavelength of light they used...

It says infrared.

“This principle was mathmatically cast in doubt some time ago. “

Probably over my head, but I’d like to hear more. Have a link?

[cydcharisse]

I’ve always maintained that with a simple system of krypton atoms this could be done.

[mikrofon]

I hate it when your retort is already used by Post #2, and you have to read through the whole d*mn thread....

Then, with far shorter pulses of extreme ultraviolet light on the 100-attosecond timescale (an attosecond is 10-18 second, a quintillionth of a second), they were able to precisely measure the effects on the valence electron orbitals.

Electron “Motion” is no quite the right term for what they observed. Overstating for fame.

[valkyry1]

There are no electrons, there are no particles. The entire universe is but a dream of God.

[decimon]

Okay, it was infrared except for when it wasn’t.

[onedoug]

Official CIA Field Hat. I´ve got mine!

[Moonman62]

The physical demonstration of attosecond transient absorption by the combined efforts of the Leone and Krausz groups and their colleagues will, in Leone’s words, “allow us to unravel processes within and among atoms, molecules, and crystals on the electronic timescale” – processes that previously could only be hinted at with studies on the comparatively languorous femtosecond timescale.

Languorous... I know that's how I always describe the femtosecond timescale.

[decimon]

Languorous... I know that's how I always describe the femtosecond timescale.

Well, femmetosecond...

[SunkenCiv]

Thanks decimon.

I didn’t forget about the cat. He’s dead in the box over there.

This principle was mathmatically cast in doubt some time ago. Logically it doesn't make much sense.

Wikipedia doesn't mention any doubt, and the idea is a cornerstone of quantum theory.

Nothing in Quantum mechanics makes much sense in our macro world, but it is "true" nonetheless. Please post a link regarding the doubt around the math behind the Uncertainty Principle.
