Nobel Prize in Physics 2023: What Are Attosecond Lasers Good For?

Today we talk about the Nobel Prize in physics, yet another superconductor retraction, whether Integrated Information theory is pseudoscience, why antimatter doesn’t anti-gravitate, sand that flows uphill which I swear has nothing to do with antigravity, the world’s most powerful X-ray laser, how life could come about on other planets, why we might go extinct sooner than expected, and of course, the telephone will ring.

I’m in Anne L’Huillier’s class. She is a really great lecturer who did not cancel the lecture even when the Nobel committee called her.

[TheLandauMinimum]

Anne L'Huillier was my master thesis supervisor and she is such an incredibly humble person. When she taught us about attosecond physics in class she never even mentioned her own role in the subject's development. Seemingly her only interest was teaching it to us.

[ScoriacTears]

I like the the creative weight imbued within the order chosen for the tetradic complimentary colour scheme of Sabines buttons and the way they contrasts with the blue of her blouse. . .

2:44 🎉 "Whooo Physics!!!" ♥ Sabine 🤗 happy 1million subs

[Drenmii]

I am certain I heard: "Sand flows downhill when it is bored", which would be an even more fascinating finding (tying into IIT),

[saitougin]

2:41 "I love it, when the Nobel prize in physics is awarded, because everyone is like 'whooo, physics!', which is how I feel the whole year."
Yes, wonderful!

"It might even get people interested in physics - for about an attosecond."
Well urgh, yeah. That's probably true.

[danielmcwhirter]

I read a similar article, the continents converge to one, but the extinction was ruled for the horrible weather that would result for most life being located so far from weather-moderating oceans (one really big ocean!).

[nickallbritton]

interesting times fs. One of my professors is extremely interested in ultrafast dynamics, especially AOS. I worked with him over the summer studying HHG in Mn2RuGa computationally using DFT + dynamics. It was interesting research and he wanted to hire me on to keep working for him over the summer but there isn't enough funding. I also was supposed to attend the APS meeting in march and submit an abstract for my work, but they could not afford to send me and I can't afford to go. Regardless, I'm really interested in this topic and looking forward to doing more research


EDIT: Not sure what changed, but they are paying for my travel expenses. So, I'm going to my first APS meeting in March. Super excited and nervous! Wish me luck

I'd like to see someone make anticobalt-60 and see if the asymmetry of its decay is the same as cobalt-60's or the opposite.

[martynspooner]

Though I understand very little due to my lack of education, I simply love this channel, thanks for your great work.

[paul-nphf]

Yeah from femto photography to atto photography opens new window to understand quantum mechanics how electrons take or lose energy by quant or even more to atto chemistry, atto computers.

[carlosalbertoteixeira]

For a series of reasons that are beside the point at the moment, I spent a few months without being able to watch your videos on YouTube. But today I started again and I must say that it brought me great joy to hear you onde more. You look more splendid than ever and your selection of themes is unbeatable. And I love it when the phone rings. Thank you very much for your excellent and instructive work, dear Sabine. Greetings from me and my family from Niterói, Rio de Janeiro, Brazil 👍🏻💜🖖🏼🌸

[marknovak]

Even 40 years ago, a lot of scientist who studied the matter seriously did not think life would make it past 900 million years from now due to the brightening sun and carbon cycles.

[blech]

“Just for context, that’s really short!”
I just adore Sabine!

[SimonDoesmath]

Just found your news segments. Awesome content! Thank you

[marvintalesman]

7, 20-8, 16 Bravo Sabine. The most exquisite example of accurate interpretation and correct definition (naming), of reality and events..

[benmcreynolds]

I really enjoy that group of scientists that were hypothesizing about Auto Catalytic reactions. That's such a good way to approach thinking about life 🧬 *the mechanical uses of that nobel prize sounds so useful and i can't wait to see what benefits it might bring.

[edreusser]

I find this kind of response very gratifying. The fact that science has a quite stern and proactive system of examination and reexamination of significant results means that those papers that do pass through this gauntlet of peer-reviewed scrutiny are far more likely to represent real progress.

[Mark_in_MKE]

Professor Hossenfelder: Who makes the physical structures that you have displayed in your videos? I'm wondering what combination of plumbers, electrical engineers, and other mechanical engineers are used to construct these huge powerful instruments.

[personal]

Great idea to have a quiz to validate what we learn from your videos. Thanks again 🙏🏻
