Attosecond Lasers (2023 Nobel Prize in Physics) - Sixty Symbols

An analog square wave? The sewing needle of eternity weaving its web through all directions at all times in all of space.

I earned a BS in physics in 1960. When I first heard of lasers, I thought, "So what?" I am ashamed to admit it.
A Musician would understand and appreciate the harmonics of light.

Funny like Mike said at the end, the universities are simultaneously promoting and denouncing the same tables as good research and bad research.

Anyone notice how that looked like an Omega symbol.

off the shelf cheap! do physics! there's really barely anybody trying. great works all yet to come. get you some!

Brilliant and fascinating video! Thank you

With a Fourier series you cannot make make any frequency higher than the highest frequency in the series. So that claim is false. So he has not explained how this works.

We only have to wait until we collectively turn 31,536,000,000 years old to have the number of seconds equal the number of attoseconds in a second!
By that point, the sun will have devoured Mercury, Venus, and the Earth about 10 billion years prior during its hungry red giant phase, and will have become a carbon-oxygen white dwarf soon after.
If the universes model of dark energy has w = -1.5, we’ll have a couple billion years more before the Universe rips itself apart at an atomic level, all non zero distances becoming infinitely large, cosmic strings disintegrate and the very fabric of space and time unravels.

Unfortunately, it’s looking more and more like the true value of w is less than -1, so no cataclysmic disintegration for us.

Only a long, dark, cold and lonely slide into oblivion as one by one, the lights in the universe go out as space expands infinitely, and we lose sight of everything except the local group we call home.
So hold onto the attoseconds while you can!

You never know when you’ll blink, look up, and that dream of becoming old enough to have your attoseconds equal seconds in your age has come true, but everything changed when you weren’t looking and you can’t even reach the other stars because they’ve gone beyond your cosmic horizon.

Now waiting for the Porthosecond lasers.

I play video games for long time ago and I always pay a lot (💰) to get maximum FPS (Hz) in my games which today I have 360hz screen that i believe its maximum for this days (2024). Question: what is "FPS" of REAL LIFE ?

Lots of scientists got Nobel prize related to lasers. A laser light is a Bose-Einstein condensate of photons which follow Bose-Einstein statistics. Professor Satyen Bose was not awarded a Nobel prize. I think it was because he was a dark skinned Indian living in pre-independent India.

When electron emit energy n comes down it's mass should come down but less mass electron to goaway from nuclie as force of attraction will be less.

So he is saying we still need the soeed if 10 to the 27 to see a electron... maybe just admit its a wave and not a particle🎉

I'll bet the first pico-second laser experiments were giant finicky monstrosities that were completely unsuitable for "real" lab work. Now he has a little box on his table that generates them with relative ease. This, I figure, will happen with Attosecond lasers fairly quickly. Just my hunch...

to win a Nobel prize: step 1: have a cunnie on your team

Damn I knew it!!! Then standing light waves must be possible aswell

This seems to be a misnomer since the smallest time that has been measured roughly a block of 250 attoseconds?

ZEPTOSECOND!!!

Talk about being fooled by mathematics

if its anything like the image of the blackhole its a joke,. that black hole image is a joke

You can tell this guy is on serious mind altering medications most likely anti-psychotics

What will ASM do with this?

It seem like you could make a smaller pulse with X-rays instead of light wave. (CC) Troy Frei

Increasing the detail of micro and macro reality will be coming blisteringly fast once the smoke clears. Neutrinos and these discoveries and AI taking over with quantum intelligence and discovery platforms-cool.👍

Did they use the sound of lightsabers while talking about overtones ?

I can feel happyiness of this man. This is the way we all should do our works and feel, find what make you feel like this and go for it.

Can this idea be used to better measure the existence of virtual particles? I know they are simply an analogy, but it still makes me wonder.

I’m still blown away that they witnessed elections actually orbiting. I just assumed orbiting was an analogy. What on earth stops the electron immediately ploughing into the nucleus.

This is kinda coincidence

Gotta love how the security cable on the filing cabinet doesnt do anything.

Time is the number of curves in space. If you increase the number of curves you get atto. Frequency is recurrency of curves. There are more irrational numbers between 10 and 20 than between 1 and 2. Irrationals are highest between power 8 and 16. Beyond power 16 they reduce and almost same. That's why red shift.

How they come up with this idea? I don’t even comprehend what he is talking about. lol. Went over my head. Luck me lot off smart people in this world otherwise I did not have a chance to survive 😊

Small corrections: First, the characteristic wavelength of the incoming primary light 10E-6 m, not 10E-15.

Second, "ordinary" femto second lasers also use the overlapping wave principle, so this is nothing new. However, they cannot reach these extremely short pulse lengths, because there are no laser media available to cover the necessary frequency spectrum. For instance, titanium sapphire crystals "lase" from about 700 nm to 1000 nm, so if you build a femto second laser with that, you have these 300 nm range to play with - which is quite a lot, but not enough to go to 10E-18.

Suoer explanation! Many thanks!

"Ultimate shutter speed" is a good analogy..

I understand half of what I just watched which is twice as much as I could understand before I started following Sixty Symbols.

Now women can make fun of our efforts in Attoseconds.

So they have this incredible fast laser strobe-light, blinking so fast, you may get a blurry image of the electrons, zipping around the nucleus. Did I get it right?

I gotta agree, this seems pretty early in a field to award the prize. Calculating an amount of time by summing observed wave forms just feels a bit far off for me 😮 Its not as if they are generating attosecond pulses, which is what you would need for scientific application. As the prize was intentionally not awarded to theoretical physicists, it seems odd

Ok maybe this is a dumb question but if you can exactly pin point the location of an electron and then exactly pinpoint its location a fraction of an attosecond later, couldn’t you calculate its velocity with that information? Would a sub-attosecond frame rate then violate the uncertainty principle?

If we can learn how to say your names…it would be very nice if you look up out of respect and just call the person on his name!!! His name is NOT Frank,Franc….and bla..bla…His name is Ferenc…..Thanks..

Now that they've done this, can I just get my dishwasher to work?
