RE: wave/particle dual nature

"The electron may appear to be a particle, or a wave, in free space, depending on its interactions with other matter, energy, and observers."

We're made of those little particles.. we're waves it seems to me. Maybe we're matter only in the eyes of observers.

thats not fair! You changed the outcome by measuring it.

Curious what the frequency of the laser... apparently 2 lasers were used... one to excite the atom and a second EUV laser to capture an image.

Post pics or it didn’t happen

An atom with a pulsating positively charged hole in the valence shell? This is a family friendly website.

Interesting, but why the hell is the Air Force spending money on this research?

Dumb question. One word answer: Weapons.

More in depth: Freer electrons equals a net reduction in power loss in anything electronic. It will be cooler, faster, and more efficient. That applies to a bunch of things the AF holds dear from onboard avionics, missile systems and future energy weapons. This is exactly the kind of thing the government should be funding. Like the atom bomb the nation that develops a lead here will be in a much better position than the ones who don't.

It is the transferred laser energy that excites the electron to leave it's valence orbit.

Figuring the speed of laser light (energy) at 3*10^8 m/sec * (the time being) 1*10^-15 = 3*10^-7m * 39/36 (converts meters to inches) = 3.25*10^-7 inches

That is the laser's wavelength, not necessarily the pulse length.

Did the atom have a cigarette afterward?

My understanding, not being a professional physicist, is that the electron is confined to one of several energy levels when it is bound to the atom. Applying enough energy to free the electron (known as the 'work function'), allows the electron to have any energy level, and can move freely. Free space is essentially a continuum of an infinite number of very closely spaced energy levels that the electron can occupy.

An electron is a wave function when bound to the atom.
It has no single position, but appears as an 'electron cloud' around the atom.
The electron may appear to be a particle, or a wave, in free space, depending on its interactions with other matter, energy, and observers.
It's always a particle and a wave.
It's called wave-particle duality.

Ah, you agree with him. Now I ask you, what is the temporal reference frame of this freed electron?
