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.

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.

For the antimatter antigravity experiment, I was under the impression that the team measured the number of antihydrogen atoms that fell and compared it to the control experiment which measured the number of hydrogen atoms that fell. These percentages were nearly equivalent. If the number of antihydrogen particles that fell was less, it would indicate antigravity. They didn't actually measure the speed of the falling particles. Anyway, a null result is a valuable result.

@SebaBuenoHaceMusiquitaJijiji

Should they try with antimolecules ? I think it was not a 50/50 btw, it was 3/4 vs 1/4, and most of them went by the lower side. If they were 50/50 that might indicate they are indiferent to gravity, and that wasnt the result but gravity affects them. If they went by the upper side, they would have been affected by antigravity, I think (and I have questions about that, is antigravity suppossed to be, for this experiment in the case it resulted, antimatter being repeled by normal gravity created by normal matter?). I MIGHT BE WRONG, but I was listening to this experiment I think in Anton Petrov's channel. Edit: yes, he talked about this yesterday

I work on this experiment. You're correct that the speed of falling particles was not measured, but rather the number that fell vs rose. For the non-biased magnetic field, 94.5 fell down and 36.7 fell up. That is after subtracting a background in the detector due to cosmic rays, which is why it's a decimal. That's 72% falling down, and many sigma from 50%. And the antihydrogen isn't too hot to combine into H2, but first it's not even close to dense enough, and second, the groundstate of the H2 molecule doesn't have a magnetic moment, so H2 wouldn't be trapped in the magnetic minimum trap like H is.

Hey Sabine, I'm loving taking the Quizwithit's quizes, they're super fun! I couldn't check the quiz's answer even though I signed up, though. Also, the background color for when you select an option by clicking on its button is too similar to its unselected version, you might want to increase contrast a bit. If I might make another suggestion, after I submit my answer, it takes a while for the quiz to move to the next question. That's not a problem in and of itself, but it might be better to add a loading animation like a rotating circle of something. As it is, it seems like the page is frozen. Happy physicing!

Sabine is my new favorite, since the video about Web3 at its 9:23.

I once attended a lecture on consciousness by a well known professor whose name I've unfortunately forgotten. He never defined the subject of his lecture, but it became apparent that his implicit definition was: 'consciousness is what neurons do'. Unsurprisingly he concluded that nematode worms are 'somewhat conscious' while machines can never be conscious! When asked for evidence of nematode consciousness he produced a microscope slide of a dissected worm and declared 'look - neurons'! All sides of this debate are indulging in pseudo-scientific hand-waving until there is a mutually agreed definition of consciousness independent of any theory of how it works or arises.

I love this stuff, although as I dropped Physics in school around the *age of 15, all this is way above my paygrade! Although it is probably impossible to get anything close to Plank time, I’m sure a quectosecond laser will be developed at some point in the future, which might make the study of exotic sub atomic particles without the need hadron colliders (if my limited understanding of the subject is not too incorrect).

good video as always.

I agree, so many people turned their nose up at the alpha result but it was a beautiful experiment and had to be done. Most (not all) reasons that people normally give as to why antimatter should fall down, were actually not correct. I believe Aegis countered most of the arguments in their first paper and there is a wikipedia page too I think. It would have been an amazing revolution in physics had it fallen up. I still think they should do more work to make sure that the result fits more squarely over g and not just barely covers it with error bars (wasn't it like 7.5 +- 2.5).

honestly. i'm on board with labeling any theory of consciousness pseudo science, because as of yet, we've got no clue how to even determine whether something is conscious or not much less know what it is & how it occurs, the problem is, consciousness is a very subjective thing. only you can be sure that you're conscious. thus making objective scientific theories for it would be very hard. unless we can figure out a way to test whether something is truly conscious. we have no theory of consciousness, and thats the problem.

Cooper pair-laundering heavy phonons (Nb3Sn Tc=18.3K) replaced by light Frenkel excitons (Tc=2200 K). The mm+-calculated solution is a molecular coaxial cable: staggered pi-stacked aromatic exciton sheath; insulator interior fully decorating a central slightly helical polyacetylene conductive core quantum well array. Each synthetic step is well-documented in the literature. *Subsisto stupri circum ac solum facere.*

A saw an online lecture with Daniel Dennett a few days ago. He was one of the IIT signatories, and discussed it as one of the lecture topics.

Sabine, please give more explanation about attosecond light pulses. Taking light speed into account, these pulses would have a length of less than a nanometer. How do I imagine such a pulse? Does it have the shape of a tiny pancake? How many photons are in there?

The mind is an emergent phenomena that arises from the hierarchical interactions that take place in the brain, It exists because the consciousness is smeared across time. The "present moment" is actually about 100ms long, You can consider this like having a huge slew rate - or, a huge lag. This is a significantly huge amount of time compared to the amount of time it takes for individual interactions to take in the brain. This would lead to systems having informational feedback, that would cycle within the time window of the present moment. Which would be a good condition for emergence to happen. As Information processing spreads across time, it also spreads across the system, and each moment of the awareness is looking backwards at itself, in this sort of self re-iterating cycle the marches forward temporally. Then, the information that the brain is getting from itself, leads to a self-modulating, guided rerouting of pathways. And this leads to the sense that really matters, the ability to sense the self. I think the ability to sense the self is a sense just like vision or smell... except there is no external receptor for it... it arises from the cycle of feedback and self-modulation, that just goes on forever until you die. :D Unfortunately it leads to this sort of conundrum of awareness. And that's brains! That's what the mushrooms told me. Usually what they say is half true and half lie... so I'm probably half right.

To get attoseccond pulsed laser light, take a femptosecond laser and shine it through a cell that has a high non-linear coefficient, hydrogen or methane work well. Then take the output and use negative dispersion mirrors to stack the modes on top of one another. It shortens the femptosecond pulse into attoseconds. It is usually a diode pumped Ti:sapphire laser sent through crystals that make UV then use the UV to pump a wide band optical parametric oscillator and use a special mirror to cause the frequencies to stack on one another.❤

The only reason to think antimatter would exhibit antigravity is that they both have "anti" in their name. We would have been spared this concern had it been called "conjugate matter". edit: still, it's a good experiment

@Cythil

9 ай бұрын

Calling it anti was not the worst move, however. A lot of stuff has worse names. The only thing is as a problem is that it makes regular matter seems like it the normal matter. It sort of is since that is what we come in to contact the most. But as far as we know, there is nothing fundamental different between matter and antimatter. There just two kinds of matter that happen to annihilate each other when in contact with each other. And as far as we know, one kind just happened to dominate our universe. (And while some see this as an odd that one is dominated, we should also remember the anthropic principle. It may be that in a thought of random chance we ended up in the universe where matter dominates. And we would not be able to exist in a universe where one did not dominate, since that universe would be pretty much empty of matter. And if we were in the antimatter dominated one, we should see the exact same thing. Why, I do not see this as a problem in itself.)

I would call it a room temperature misconductor!

this channel is what we need. Finally the algorithm spat up something that was interesting , informative and not just baity.

I think somewhere along we've sort of missed a step with polar charge particle models, they're easier to model and do the math for, and certainly to create, but it seems much less accurate than if we adopted a truly 2 or 3 dimensional model where it isn't just linearly positive or negative.

How does one measure an event that happens in an attosecond? Or is it just calculated?

The laser light used to form the atto second pulse has no mass, but does have momentum which could affect the movement of a charged particle. Is this another case of observation interfering with measurement?

1 attosecond is my attention span since the invention of social media.
