Faster Than We Thought Possible - Nobel Prize in Physics 2023 Explained 

I think most scientists are.

You can absolutely produce a single photon but that isn't that useful for imaging but does have a lot of other uses. In this case they can have a lot of photons that are all arriving at the same time.

A single "photon" is a wave, not a particle (wave of probability) and the Heisenberg uncertainty principal is fully in effect and results are random. You only can image things when you have deterministic results, collapsing the waveform of both the electron and the photon. Note that this does change state - it isn't passive.

​@@ScienceDiscussed how do we interpret the concept of 'shortest light burst'. Does it refer to the time between one photon arriving and the next?

I was referring to the pulse width rather than the time in between. Both parameters matter and both can be tuned by various means.

There are a lot of questions about the reproducibility and/or interpretations of a lot of capitalist-influenced science. Light seems to be a major one. Every "single photon" emitter I've read about, it turns out, sends "packets" of photons, but they call them single photon emitters, I think, because it fits the narrative of the physics' status quo, aka Dr. Whitten. My spelling might be off, but he's the author of M "Theory." He's why string "theory" (hypothesis, not theory) became so prevalent and string hypothesists got into the upper echelons across physics departments nationwide. He also pushes for the big bang, ignoring gravity's effect on red shifting to make it look like the universe is expanding. I'm not saying it's not, but the behavior of popsci-influencers and the news around the topic is sus, and I *am* saying that a lot of scientists have ignored the scientific method and any variables that work against the narrative of their benefactors or their own preconcieved notions, i.e. "the chemical imballance theory" of depression, everything to do with anticholinergics, lead industry funded studies of lead's toxicity, and when scientists told us that cigarettes are good for you.

Thanks, I am glad you liked it and welcome.

Brute force method of hackers finding all of my passwords lol

There are encryption methods called vector encryption.

Nah, in the Corporate states we gotta worship cons like Musk and Bankrupt-Fried and Bloody Holmes and Bezos and millionaire who plays a billionaire on TV O'Leary, etc. etc. They're billionaires you know.... until they're not and their frauds fall apart of course.

Well, I hope it helps in advancing the science to such a degree, that people stop perceiving an electron's movement as if it's some sort schrodinger's cat, simply because of ya don't have a good enough camera.

Glad you enjoyed it! Always happy to have more Canadian on board.

off topic, but electron microscopes make me SO HAPPY that bugs are small. Or that I'm big. They're literally monsters!

Thank you very much.

Glad you enjoy it!

One universe per second

@@JonaasK to boldly go towards Planckoseconds = 10^-44sec.

can we finally measure the position and momentum one electron at a time?

The measurement is still limited by the Heisenberg uncertainty principle. So with the extra spatial information come at the cost of less momentum information

@@ScienceDiscussedhmmm... but maybe its still possible to "follow the trajectory" of one electron... hmmmm...

Yes this is the idea, to follow the trajectory of one of the electrons around the molecule by taking snap shots in time as to where it was.

To bad for those so called noble prize Winners.... hahahaha .... they did not present any registration of electrons observed. Only words and graphical simulations... plus you can’t pretend or insinuate to have violated the Heinsberg principle of indeterminacy with zero empirical material evidence. Any scientist must wonder what the hell is the motivation behind this prize.

It is a great question. I didn't look into what type of detectors they are using. But no detector will be able to be reset in that timeframe. So I would imagine that they send a pulse of light, detect it, reset the detector, and then send the next pulse of light.

@@ScienceDiscussed I am working in this field and we are normally doing the so-called pump-probe experiments. We send the attosecond pulses together with delayed infrared pulses (most often we just split the IR pulse before harmonic generation and take a small fraction of it to act as a probe) into matter and look at and detect the electrons ejected through a photoelectric effect. Then we vary the delay between the attosecond and IR fields very precisely, which in turn affects the properties of the ejected electrons. These electrons can convey a lot of information about the pulses themselves or the system that we study. (People often call it "taking a series of snapshots at different delays and thus making an electron movie".

@@ivansytsev2581 thanks for sharing the details of your experiments. It sounds awesome.

Good question! The plank length or time is still much shorter. An attosecond is 10^-18 seconds while the plank time is 10^-44 seconds.

I can plank for 1 minute.

Is the spelling “plank” acceptable?

@@TheYurubutugralb Planck is the correct from if you're referring to length

The pulses that they showed back in 2001 were 250 as long and they could produce them in a train or as a single pulse.

@@ScienceDiscussedhmm... i was thinking about that camera frame analogy. even if a pulse was very short, if it took much longer between pulses we wouldn't really get that many frames...

Yes this is true but you can see get a snapshot in time as to what is going on.

Haha thanks. To be honest I had it done earlier but I wasn't happy with the thumbnail which delayed it by a couple of days.

Good spot. Clearly I wasn't thinking very hard while I was editing that section.

the reduced planck constant is around 10^-34 Js, diameter of an atom is around 10^-9 meters, so you can still get very precise information about position and momentum at least theoretically, although I don’t know anything about the field so take that with a grain of salt ofc.

i'm uncertain about that paul

Yes higher frequencies help to make short pulses because the interference pattern is more tightly packed.

@@ScienceDiscussed imagine if the technique is applied to, lets say, X-rays!

I think there is similar work in X-rays but I don't know off the top of my head.

You're welcome!

Unfortunately that’s not what’s on the table concerning this breakthrough, that is fundamentally not possible, the more you try to prob for information the further nature will sensor information about it, that’s why quantum makes everyone’s lives harder. You can’t really break the uncertainty principle, you can only get closer so to speak, a zenos paradox

It is a great figurine and I think you are the first person to mention it.
