- Опубліковано 16 жов 2023
- The Nobel Prize in Physics 2023 was just awarded to three scientists (Pierre Agostini, Ferenc Krausz and Anne L’Huillier) for "experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter." In other words, they broke the record for the fastest light pulse! And that's allowing us to peer into the inner workings of our world and understand things like never before...

Cleo is the type of ethusiastic teacher that every one of us really deserved.
The looks also help instead of a old groomy man
Helps she's a 9/10, i can listen to her talk for hours, but helps i can also look at her face for hours too...
Honestly, I can be dumb as a bag of rocks but the explanations are all things I get. Definitely enjoy learning things with her 😂
Perhaps, but because she's so good she wouldn't have become trapped in the education system as another overworked and underpaid victim of greedy economic policy.
@@wza223-fo3mc Simps? Wow you incels throw out the projections like crazy.
As a laser physicist, I think it's worth noting that these aren't "fast pulses", they are "ultrashort pulses". The speed of light is always the same, the trick is that the pulse duration is short and thus allows us to observe ultrafast events. Ultrashort pulses enable ultrafast science.
Edit: Got a surprising number of likes on this so maybe Cleo will actually see it. If so, I'd love to help you make a longer video about the exciting fields of ultrafast science and show you our labs where we actually make these sorts of pulses and some of the crazy things we can do with them.
How are they generated that this is such a big deal?
@@iRossco its einsteins photoelectric effect in action.. argon gas re-emitting photons which are split and processed in a cool experimental setup.
Thank you so much. The moment I heard ultra fast, I had that doubt. You cleared it.
@@VaradKalyankar No, this is very incorrect. It's quite a bit more complicated and is primarily described by Paul Corkum's three-step model when a gas is used and by the semiconductor Bloch equations when a solid target is used. The emission of the high harmonics necessary to construct the spectral bandwidth of the Attosecond pulse is known as "High harmonic generation" and is a nonlinear interaction between the driving field and the dipoles of the medium (in the classical view). It is categorically not the photo-electric effect.
@DAVOinIN I could have sworn I read a paper within the last year or so about scientists slowing down a beam of light causing it to clock in just under the speed of light... Then again, it could have been a similar misnomer as we are experiencing here.
People call me lazy because they don't think I move. I just move so fast they never see it.
😂😂😂😂😂😂😂
Like Bruce Lee
I saw what you did there
no youre just lazy
When shown a bag of doughnuts, sure you do
In case anyone is confused, the pulse itself is not moving faster than any other light, all light moves at the speed of light. The "speed" is referring to the length of time the pulse exists. Like a tiny bump on your car horn vs a proper angry press. So ya, this pulse is very very short but still moves at the speed of light through space.
polite photon toots.
whoa, whoa, whoa, i'm not here to give you melanoma! just a lil vitamin d.
A pulse that short will undoubtedly be very high energy and wreck your dna. @@plumbthumbs9584
Light travels at the speed of light only in the vacuum, if it's through air or glass or water, it travels slower. Other than that, correct.
No that is incorrect. The value of the speed of light is dependant on the medium but and it does change but whatever value you have is the speed of light. The change of the speed is due to the refractive index of the material.
We refer to the speed of light in a vacuum as is 299 792 458 m / s, while in water it is 225,000000 m/s but in both cases that is the speed of light. The speed in a medium is calculated using the law of refraction v=cn where N is the refractive index of the material and C is the speed of light in a vacuum.
This is to show that regardless of the medium the light travelling through it is travelling at the speed of light for that medium. No faster speed is possible in that medium since it is the speed of light.
@@tymondabrowski12
how far did it travel ?
Scientist after creating the first pulse:

Every picture taken of an atom, which is astonishing on its own, shows the electron field as a fuzzy blur. I would love to be able to see the structure of the nucleus with a snapshot so fast, that it can finally capture the electrons in still. That would be fascinating.
You can't image the nucleus with the sort of wavelengths they are producing. In fact, the wavelength that would be required to image the nucleus might be too short to even be feasible (haven't done any estimations, but wouldn't be surprised if it was the case)
You can’t see electrons in one place at a time because they don’t exist in one place. In a single moment of time an electron exists as a wave of probability of where its influence is higher and lower, it would still be that fuzzy cloud. They aren’t actually moving to create the blur, they exist everywhere in the blur at once
Yeah, that is impossible. If that ever happened Heisenberg would roll in his grave.
Perspective on how small this is.
If an atto second would be a second - one second would be more than twice the age of the universe.
Wow! I kind of grasped it had to be super small, but never expected it was THAT small! Thanks for that comparison.
This! It blew my mind. I saw a numberphile video on this topic recently and when he said that I had to pause it just so that scale could sink in.
@@ItaloBarbiero my girlfriend:
Omg
Sorry to be that guy but while technically true, one second would actually be around 73 million billion years
Cleo's enthusiasm is proof she would be a great teacher
And her view counts are proof that her enthusiasm is better leveraged on UA-cam where she can reach millions than in a public school where she can reach hundreds.
i believe NOT ,, why ?
she don't report
a
subject or maybe two
very well or not the truth .
She is a great teacher*
I would love to be in a class with her as my professor. Maybe I would have passion for the hundreds of thousands of dollars my parents spent on me then.
uhm... she is? Her YT channel is leveraging that talent the best actually.
For comparison, that video is 4.6 QUINTILLION attoseconds long
Never heard a girl say "that is just so small" with that level of satisfaction
Same thought man =p she`s keen on small things :D

I really appreciate that the Nobel prize can be won by more than one person. If multiple people contributed to the project, it’s only right they all get credit.
Sucks for the fourth person, tho
@@DrDeuteron yea I feel like they really should increase that limit or at the very least give the team a shout out because today science is a team effort (sorta always have been honestly but that is stuff that is often swept under the rug)
@@link7417i agree with you
noble prizes are honestly just plain stupid,
Yeah the they help highlight research but still they shouldn't shouldn't giving credit to just a few people
@@hemantjain2387 mhm it gives a very sqewed picture of how science works for the very least
Been working on something, a collaborative type of prize we can award... to citizen science. Gather a bunch of everyday people who do citizen science, they work with scientists in an open livestream and result in a major discovery, and the prize goes to: citizen science. Instead of to any person.
If you want info, feel free to ask.
Just measuring time at that scale is impressive!
This attosecond pulse still isn’t faster than me running up the stairs after I turn off the lights
The proof of human use of the brain for the right thing.
To get an idea. There are more attoseconds in a second than the number of seconds since the big bang.
What? I give up.
Eh???
Interesting, has the Big Bang been proven?
At first I was doubtful. But, this is actually mind-bogglingly true
Brain hurty ☹️
Its worth noting that most of the processes she was talking about takes place in the femto and picosecond time range. Which was cover in previous Nobel prize winning research usin Ti:Sapphire lasers. This research verified the existance and movement of electrons within atomic and molecular orbitals. This technology requires X-ray laser and therefore cannot be used for a number of the applications mentioned as its ionizing radiation not useful to optical and electrical characterization. Unfortunately, you need wavelengths this small as the pulse must be equal to or larger than half the wavelength. This severely limits its applications.
I was in the building where they did it, it's all really cool looking!
I'm immensely happy that Cleo can carry the torch of condensed and useful bits science now that Tom Scott is retiring his channel and Dianna is fighting long COVID. Thank you!!
Yeah no, Cleo is great and her contribution to get younger people excited about science is great. But she’s no where closer to Tom Scott. Her science videos have the depth of a Wikipedia article written by a high school student.
Her videos are surface level Wikipedia articles graphics at best without any original insights.
@@ridhvikg Wikipedia articles can get pretty hardcore. That's why there's a Simple version.
"THAT IS JUST SO SMALL"
*Followed by a laughter*
_sighs in L mind_
She’s hurt some men’s feelings in the past 😅
🤝
Anne L'Huillier works as a lecturer at my University. She seems like a very nice person and appreciated by her students.
I don't think it's a coincidence that Nobel laureates are loved by their students.
@@adamroach3771 perhaps not. Just to clarify, i meant before she even got the nobel prize
"We can see things we couldn't before."
*Shows character creation screen from Spore*
*"That is just... So small"*
That's LITERALLY what she said 😂
Fr tho she should consider his personality or something
Ha.
😐
Shouldn't it be "short" since we are talking about time and not size? English is not my first language.
@@bpop2148 She's talking about the value, or the number. (That's what you're referring to right, i forgot this video) You may never describe a value(itself) to be short

I have seen some minutes of the ending of that Livestream of then getting nobal prizes, but for out why today-
I remember they also mentioned a chemistry nobal prize after that.
Still waiting for a pessimistic science news channel
Thank you for your videos! You really bring the joy into subjects that are not that interesting to normal public! Cannot wait for more!
Finally Leonard, Amy And Sheldon Cooper Did Something Together. 😂 ❤
LMFAO😂
I was literally going through the comments to find a Sheldon related comment 😂😂😂

This has major impact on fiber optic networks as well the faster the pulse of light the faster the data can transfer.
Do one about how they actually measure the time intervals involved and how they know with confidence.
Grad student in physical chemistry here: there are a number of ways to do it. For laser pulses on the femtosecond and picosecond timescale, we use a technique called autocorrelation commonly paired with a spectrometer, which in total is called Frequency Resolved Optical Gating (FROG) Wikipedia has a great article on it, but the premise is using the pulse to measure itself, it's pretty neat. With attosecond pulses, it becomes a little more complex, but the general underlying principle is the same.
I absolutely love her channel!
Cleo's excitement about science is contagious, and I love it!
The electron knows where it is at all times
The attosecond may be small, but I bet he has a good personality 😊
Hell yes! I'm so intrigued by what opens up when we can image electrons. Especially given their more inherent quantum nature than most things we observe.
I've been able to imagine electrons ever since I heard of them. To think some people claim they are real!
Yeah, electrons aren't things, but carry on anyway.
@@Pimp-Master what?
Soo proud of Ferenc Krausz a fellow hungarian 🇭🇺🏆

When I went to school, it was the beginning of A/D converters. The science that you are covering is way beyond my imagination. All these decades later, I am glad that I have lived long enough to watch your videos, specially this one covering wavelengths and how that information can be used, how you teach is amazing.
I live in world where cleo's enthusiasm & excitement like no other people !!!!
I love , science even more... Especially with these animations & way teaching/sharing us like a best friend is incredible.
Best explanation of attoseconds is the fact that during one beat of a heart more attoseconds pass than heartbeats would since the big bang
The subtitles are hidden behind the channel info text at the bottom 😢 can you edit your subtitles up higher for more videos? ❤
This happens with the majority of UA-cam Shorts, it seems. I’m not sure how much control the creators have over the placement. But I agree, it is distracting and annoying. I wish they’d address it, now that Shorts are an absolute fixture now. 🫡 But still love Cleo’s content the most!
Next wensday one of them is giving a lecture in my university
this will open up a new world - can you imagine to see minute changes that we were not able to see before..... it will rewrite so much science and confirm what we thought we knew.... no wonder it was awarded such a prestigious award.
This is how fast woman reject me 😂

I think mine is a lot faster😂
"That is just so small"

@@arunthathypv2296i think thats average 😢
Fibre broadband using attosecond pulses is a mindblowing thought.
An attosecond to a second is what a second is to 32 billion years
At the Nobel prize presentation ceremony, the presenter simply said "Atto boy, team!"
See what I did there?
Would that change the current issue of either knowing position OR speed but not both?
I don't know about that but I heard it can help you see chemical bonds forming in real time
I mean first of all, no. But also its not a thing were trying to solve, because you can't solve it
The Faster than light Police are going to be sending you a speeding ticket.
In a flash comic he says he perceives time in attoseconds and kind of puts into perspective he has unlimited potential with speed
if sunshine was a person
Simp
I mean the amount of understanding she has to explain everything 👏
She doesn't!
Her explanations are three dimensional at best
he got an ...
"Atta Boy" award.
Notable use: Faster fiber optic data transfer. Hence, faster and cheaper internet. Or more data bandwidth available for connectivity
"That is just so small!"
Her: "Everything reminds me of him" 💀
Believe it or not, women really don't think like that.
The Flash can run REAL fast in one attosecond.
🙄
Genius.
I subscribed to your channel in a attosecond just to see u speak. Im absolutely entranced your by energetic explanation of science 😊
maybe it can be a tool to shed more light (no pun) on those confounding things that seem to adopt a super position when observed thus far by reducing the time scales on which we can singularly observe moments in ongoing events
I love this one so much because it's so easy to explain the basic workings of it. Something almost anyone can understand
I love how humans went from
"Haha, big monkey throws spear"
To
"We're using pulses of light in order to unveil the very machinations of the universe itself"
Prove that humans were monkeys
@@trainwreck420ish We grow hair all over our body, same as monkeys
@@trainwreck420ishthere isn’t any proof and there isn’t any way to test the change of kinds. Unfortunately it’s jut been widely accepted.
@@Juliosguitarstuffstheres actually a lot of proof. Now, we weren't monkeys in the way that we see monkeys now, we were a distant cousin. We started walking to get across plains and that began the change in our bodies to be more suited to walking upright. It is believed that the beginning of eating cooked meat got us the necessary proteins to accelerate brain growth, adding to our intelligence. From there we just lost our hair, began living in small tribes, then villages, then cities, and now we're here.
@@JuliosguitarstuffsAnd the proof of this is thousands of fossils.
Observing what once was unobservable might reveal things best left unlearned.
that pulse still can’t disappear as fast as my memory
There are more attoseconds in 1 second, then there are seconds in the AGE of the universe (13.7Billion years)
Would that mean higher speed fiber as well?
That's what I was wondering
Nope
@@DAVOinIN are you sure cause faster light would mean higher transmission rate, or am i missing something?
@@T2Medium_ Ya, so I'm an optical physicist who actually works in this field and the problem is that these aren't "ultrafast" pulses of light. Light travels at the speed of light (or slower depending on what it is traveling through), so you can't make light faster than the speed of light. These laser pulses are actually "ultrashort" pulses. A very simple analogy is a light switch. Whether I turn a light switch on and leave it on or I turn it on and then immediately turn it off, the light being emitted from the bulb travels at the same speed, but the duration that the light was turned on is much shorter. In analogy with a camera's "shutter-speed", these ultrashort pulses allow us to illuminate physical systems for very very short amounts of time so we can actually resolve the motion/dynamics of objects who move far too quickly to observe otherwise.
Imagine you're at a cross country event being held at night and you're trying to take photos of one of the runners with the flash on a camera. If the flash lasts for 10 seconds and your exposure time is set to 10 seconds then all you will see in the image is a blur of the runner. If however, your flash and shutter speed are much faster (say 10 milliseconds) then the runner will look perfectly motionless in the image.
These Attosecond pulses are important because electrons move very very rapidly so in order to "freeze" them in the image we need a flash-bulb that turns on and off faster than they can even move.
The light isn't going any faster though. The pulses are shorter
I can’t get enough of your content! You radiate good vibes!! 😊
Finally, light that lasts as long as i do.
Finally someone made me understand what this year's Nobel Prize in Physics was all about ❤
a few billion billionths of a second could also be interpreted as meaning a few seconds
?????????????????????
The best part i like about her is that she cut to the chase and tells "what really matters"
Love these things..
What about pessimistic science? Which channel would you recommend?
God your hair is fantastic
I like how she actually explains stuff in a way a normal person could understand it, because that's how you teach people new things. I just hope more good comes from this achievement than the novel ways our race will conjure up to end each other or this rock we're still stuck on.
I really really love your videos and content ❤
As someone who works in the data networking field, be interesting to see what this does to speed up our communication networks.
Why are you so beautiful?
Maaaan better gimme that Nobel prize too. I’m always flashing my room light on and off real fast. All it does is hurt my eyes though
Whenever I hear your voice, it brings peace to my heart. There's just this soothing vibe and comfort in the way you talk.
Best part about Cleo’s videos is how enthusiastic she is about the content she is learning!!
Maam whoever you are where you are I want god to bless you forever with good health and awesome vibin life . The sheer joy and excitement you transcend to us through this clips is something else . I jus want to pay my utmost respect and admiration for what you do and how you do the things you are doing.
Sounds like the beginning of the flash device that wiped memory from men in black.
Added bonus for fibre could be that the bottleneck of single fibre, the stable version, is now bigger.
everything starts with optimism, and curiosity 😊
I got to be at a lecture at SLAC National Laboratory where one of the members of the team researching this spoke about their project. Fascinating topic.
the way she said “that is just so small” gave me flashbacks 😞
The aliens are messing with my electrons 😭
Almost as fast I could run in 3rd grade. Good job at second place scientists
What I want to know is how exactly do you know they have produced such a short pulse? How is such a brief pulse measured?
This will also help us create the fastest internet speeds ever seen before
Drop a link for the green blob video with the attosecond stopwatch in the righthand corner pls.
surely this is huge for the future of fibre optic as well?
We’re at the dawn of a golden age of discovery and convergence of tech
The more science reveals the intricacy of life the more improbable it is we got here through an explosion.
Just thinking of how fast my internet is gonna be once they figure out how to put it in fiber
That’s almost fast enough to take a picture of the exact moment I lose interest in most conversations.
glad to see natalie Portman teaching us physics
It could lead to a monumental step in processor speed. If processor speeds increase at the same degree, our current passwords and many prime numbers used for encryptions may become useless to brute force attacks.
Cleo's obvious passion for her chosen field of study/work is something you just can't fake. 👍🏾😘
For the ultimate slo-mo camera.
That's where most of the discoveries are going to be coming from in the next few decades, from making REALLY precise measurements.
