Fucking christ, how many times is this article going to say the same thing?

(Phys.org)—Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior.

Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle. The breakthrough work is published in Nature Communications.

When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this "photoelectric" effect by proposing that light – thought to only be a wave – is also a stream of particles. Even though a variety of experiments have successfully observed both the particle- and wave-like behaviors of light, they have never been able to observe both at the same time.

A research team led by Fabrizio Carbone at EPFL has now carried out an experiment with a clever twist: using electrons to image light. The researchers have captured, for the first time ever, a single snapshot of light behaving simultaneously as both a wave and a stream of particles.

And then call it a photograph, which it obviously isn't.

Well in the latin sense, it is a graphic depicting light, so in a way it is a photo-graph. But yeah, not a traditional photo.

That would require them to remember what "aesthetics" means.

Can someone explain like i'm five here wtf is going on, and why does this look like a new windows background theme?

Science fan here, what does this mean for our world?

"Even though a variety of experiments have successfully observed both the particle- and wave-like behaviors of light, they have never been able to observe both at the same time."

According to the article, we already knew that light exhibits particle-like and wave-like behavior. So how does 'photographing' the two at the same time (which BTW the technicians did not really do) add to our understanding of light? Does it change Maxwell's equations or Lorentz's force law from which our current understanding of electromagnetism (of which visible light is a part) is derived? Is so please explain how.

Doesn't the light just collapse to a particle the moment it interacts with the electron? So they are just taking a "photo" of electron positions? What am I missing?

You are correct. It is electron positions colliding off the wave-particle transition of a photon.

I don't think you're missing anything. "Collapse" might better be described as "wave to particle transition." (Btw, it only happens from observation. -If you can wrap your head around that titanic fact.. Makes my brain hurt.)

I'm betting light is just 4th dimensional and we're just able to perceive it as particle and wave cuz thats where it overlaps in that dimension.

[–] jeegte12 0 points 2 points (+2|-0) ago  (edited ago)

by that logic, everything is 4th dimensional, since it overlaps with the third dimension

That is the basis for Two-dimensional time.
