Beyond Higgs: The Wild Frontier of Particle Physics
Вставка
- Опубліковано 7 тра 2024
- On July 4, 2012 the champagne flowed. The elusive Higgs boson-the fundamental particle that gives mass to all other particles-had been found. After generations of work, the last puzzle piece was in place and the Standard Model of particle physics was complete. So, what’s next? What is the road map that will guide physicists to the next triumphs, from identifying dark matter to quantizing gravity, and perhaps providing insight into the deepest question of all-why is there something rather than nothing? What theories will light the way? What machines will we need to build to tether progress to reality? Join a renowned group of physicists to explore how we leapfrog forward from success.
This program is part of the BIG IDEAS SERIES, made possible with support from the JOHN TEMPLETON FOUNDATION.
PARTICIPANTS: Nima Arkani-Hamed, Monica Dunford, Joe Lykken
MODERATOR: Brian Greene

That was an exciting conversation. I literally had (and still have), tears streaming down my face. At 57 years old, I'm just now starting to study physics / cosmology. It won't replace music (I'm currently studying piano), but when I can't sleep, I now watch these science shows instead of smoking weed.
💜💜
Same except I smoke weed just before lol
I've developed arthritis in my thumbs and can't play anymore. I love science, especially the very large and very small. These videos are wonderful, and i sometimes wish i took another path...
I do both. I'm a 65 year old construction worker. Very good at geometry. Anyhow. I love this shit! Science festival rocks!
I repeat as I do every time I watch a discussion headed by Brian Greene - He always keeps the topic flowing with his innate ability to sit back and let his guests talk about their particular knowledge of a subject (in their lingo) and then interpret it for all of us as if he were reading the morning newspaper over a cup of coffee. The best mediator you are ever going to find.
He is an excellent science interviewer. Very good at encouraging his speakers to talk about their field and keep it simple enough that you dont need a PhD. to follow the discussion.
really? it's an innate ability? you think he was born being able to do that? or do you just not understand the words you use?
@@sumdumbmick - you may question your own ability to use the English language so you question others but yes, INNATE is exactly what I meant. Dr. Greene has control over his ego, a quality that gives him the abilities of which I speak. People like him are gifted in that area. I have seen many so-called expert mediators in productions like this who can't control their egos and must dominate the conversations (a problem you seem to share with them). I'm not sure why you find it necessary to troll a conversation about an exceptional man like this but you can crawl back to your mother's basement now. Thank you very much.
@@78tag You're a fucking joke
@@78tag btw, you also don't seem to know what 'troll' means. somebody calling you out on being stupid is not in itself trolling. for that to be trolling would require you to be somehow vitally and uniquely important, which you're not.
This episode is worth watching several times. Thanks for making this public!
This is my 4'th or 5'th time watching! lol
After having watched this show for a fifth time, I still think it's, arguably, the best hour and a half you can spend at home in front of a computer screen.
Or TV screen. But, come to think of it, nowadays that's a computer too.
I'm on my fifth time as well, and I'd have to agree...although the one on anti-matter is a close second.
right? super on point...we need to probe higher energies
Dang right
and, it's free;-)
Nima's enthusiasm that he seems to have in most of his talks is just contagious.
That woman is a hard worker, I’ve seen her role at CERN and it is very taxing work requiring unending dedication. All the panelists present are just as dedicated and dare I say, very enthusiastic.
Much respect to all these folks, unlocking the secrets of the world is no small task, I'm grateful for their hard work because I love learning about their new discoveries‼️💯 Modern day super heroes if you ask me, our society is really riding on their shoulders
Hi
Hi
Hi Hi again
@@r.adamberk4904 hehe, looking at the same videos. Too funny… Hi.
Monica Dunford is a fantastic teacher! She can explain enough to keep the students' mind engaged, and not so much to overwhelm.
And she can explain things concisely and allows other people to speak without fidgeting while others are speaking and doesn't monopolise the conversation (i.e., Nima).
An absolutely beautiful discussion. Nima was exceptional in his explanations. The awe of discovery, the natural world and the wonder of it all is quite oddly fulfilling despite so much it it being an unknown. All of the World Science Festival discussions are awesome. Brian is a very good speaker, has a natural knack. Please never stop doing these discussions.
think nima is good and has some insight into how to explain things understndably, but he isn't very concise in his explanations. so much in fact, i would sometimes call it rants. he should work on when to stop.
@@mehridin He's annoying because he loves to hear himself talk. When asked for a yes or no about supersymmetry, he can't stop ranting and when other people talk he fidgets constantly.
@@td866 ur right.. he is a bit self absorbed. he had that "leading star" reputation in the physics community, and it probably got to his head a little bit. plus he's probably on the spectrum somewhere, so his social antennas might be bent and dented.
I'm sorry, but speaking as a published scientist, I didn't find this to be beautiful or exceptional at all. They were constantly admitting how arbitrary a lot of what they do is, and frequently admitting that they don't really know anything, aren't sure what they've learned, and can't predict anything.
I love the energy of trese people, they're so passionate about what they do. And Brian Green is very good at bringing out that passion in their explanations
I felt like Green was getting a bit frustrated with Nimas long explenations but I myself loved his enthusiasm and passion in explaining things to such extensive detail.
@@ISILENTNINJAI Brian GREENE !
they must be influenced by the higher energy.

Some thoughts:
1. This may be the greatest panel discussion on physics that I have ever heard.
2. You can tell that Nima Arkani-Hamed has an incredible grasp of these issues because he has not only facts at his disposal, but a narrative involving those facts.
3. The distance between the quality of our science and the quality of our politics is at this moment, heartbreaking.
4. Brian Greene has shown once again how important it is that a discussion about theoretical physics be moderated by a theoretical physicist.
@Marko R - good job, you couldn't have made his point (#3) better. Is that really all you have to contribute?
Eric Hodge. On point 3. Since science is fundamentally the search for truth, it is antithetical to the current political ideology. It shouldn’t be, and in a healthy society it isn’t. There are no historical precedents for societies abandoning science and reason and going on to live long and prosper. What actually happens is the dark ages.
On #3, politics is like an emotion. some make sense, some do not, and others are not helpful in anyway but we keep having them. In the end it is but a futile exercise of our species. By the way, I am a political economist if that helps. I just wish I realized that sooner before I decided on my course. Always wanted to be in the sciences but life happened and here I am just trying to partake in this side of our world.
Marko R science is humans’ pursuit of knowledge of the natural mechanics so really science is ours in the sense that science is humanity’s, not that most humans know much about most science
Agreed. I think they all know their stuff, but Nima has that infectious enthusiasm like Green and deGrasse Tyson have. He can also communicate his concepts well and treats the audience like they are intelligent.
I Literally have to go to sleep listening to Neil Degrasse Tyson or Brian Greene every night been doing this 10 years straight. Particles physics and Astrophysics, space period is the most interesting thing to me. Out this world ‼️
i started in 2017 , its the best thing ever
Lavish Leaf Wow! I thought I was the only one...
A real doubled edged compliment.
Sean carroll and Mitchio Kako and Max Tegmark are regular sleep companions, Something Deely Hidden us the epitome of frontiers of particle physics. Get Sean On . When and if he has time obviously
@Earl of Doncaster , i got memory problems due to brain injury and taking these lectures/books while sleeping defiantly enhances my recall of the facts in such audio predictions. i'd put it as a massive compliment that i like the production that much that i want to retain it. would be great {although i know it's impractical} if all frontier physics philosophy was submitted as audio files for perusal of biblioimpaired individuals. i have great concentration problems when reading. Cal the high grade M.D. lol
I was there, in the audience for this. Absolutely thrilling!
Cool I'm the only one that lesions to this stuff not any one know lesions to it's over there heads
What a treat for you to have been there!!🤓🧠🦉
Who else was beyond excited that they uploaded this ?
@Whited Out lol... shit that was funny....
Until I saw, yet again, we have to endure the ego of Brian Greene - for shame - ROTATE YOUR HOSTS LIKE YOU USED TO.
@@thinkfloyd2594 you poor narcissistic jerk. Put your hand up for the job next time.
@@thinkfloyd2594 I'd like to see a different host as well...but I do like Brian greene well enough. He at least has a personality of his own and can shoot from the hip so to speak.
@Whited Out lmfao😄😄😄
The passion that comes through these guys especially Nima is totally infectious, it really makes me feel thrilled in anticipation about what the next 10, 20, 30 years of exploration will bring us.
I believe that if he had his hands tied behind his back, he would not be able to speak.
@@Vector_Ze And he would still be fidgeting and anxious to speak when others are speaking.
Ya. You said it. Full ditto.
If I couldn't hear it, I'd wonder if he actually took a breath when he was speaking.
Yes we are waiting
Climb every mountain! Engaging, enlightening and energetic conservation about a topic that is so
important and ground breaking that it will be robustly discussed for decades to come.Sit back, take a couple of deep breaths and enjoy this ride with some of the most talented humans on planet Earth. Thanks as always to WSF and Mr Green.
UA-cam is a universe and finding this channel was my greatest discovery.
Truly mind boggling how much free knowledge is available on the Internet for ones who are ready to dig around.
Try also The Royal Institution chanel
After listening interestingly, the discussion for almost one and a half hour, finally Nima’s down-to-earth comments on preparing for reaching the tip of Mount Everest opened my eyes to how fantastic it would be to study the fundamentals ingredients of ourselves. I appreciate the professional views of scientists Monica and Joa. Fabulous! Being a civil engineer, I rather understood the building of colossal collider and was equally curious about the Higgs particle. I am happy that I have been to CERN in 2017. It made me easy to listen to your discussion. I cannot stop listening more and more to the dialogues moderated by Brian. Thank you so much.
its amazing how intelligent and logical these people are in their approach a good lesson for all disciplines
Brian green is genius.i like to watch his lectures for understanding the universe. He is definitely doing the best by keeping every topic simple and interesting.
Nima! What a pleasant surprise :)
Its always a treat to see Mr. Green. Mr. Arkani-Hamed , I heard him for the first time & dang this man is a genius.
this Nema guy knows his stuff .i am gonna follow him
As Brian is saying early on, often the prediction or theory is made a long while before it is observed. At the mention of Einstein and the 1915/1919 bit, I chuckled; Einstein also put to paper the notion of a laser, the math and physics behind one. It took about 40 years more before the first actual laser was built.
Was fortunate enough to be vacationing in New York and was able to attend this lecture. Such a great panel and a great experience. Thanks for posting WSF!
WHAT?!?!?!?!
WHAT?!?!?!?!
WHAT?!?!?!?!
WHAT?!?!?!?!
WHAT?!?!?!?!
I just loved this discussion! So well moderated by Brian, keeping everybody on track and giving us an understanding of the standard model onwards to supersymmetry possibilities. It's nearly the end of 2022 and now we have the news of Quantum tunneling with Quantum Computers and of last week, fusion! It's a great time to be alive. I wonder if in the future, my great grandkids will be able to investigate and measure subatomic particles with an at home educational kit?
Watched the entire talk, that was absolutely an amazing panel to listen to and learn from. Bravo!
could you imagine how drastically different life would be for us and every species near us if we understood reality as our bodies processed it rather than the limited realm of perception that we are in now
Every single words that came from them was mind blowing.
That was a Great Conversation. As a student I had seen Nima and Joseph in the documentary 'Elegant Universe' based on Brian's book. I had seen Monica and Nima in 'Particle fever' which was based on Higgs discovery. Now as a physicist and Cosmologist, I am looking forward to work on some of these big problems and help the field move forward. Absolutely Brilliant video this was and great insights by Nima. Thanks to World Science Festival.
Nima is annoying AF- he loves to hear himself talk and looks really anxious and fidgets when other people are speaking.
I feel so lucky to hear about these things, so grateful for these generous and curious and devoted people.
Good subject to probe Brian Green. Happy new year to entire panel for projects in 2022
Great teachers and love the way Brian Green coaxes them to reveal further and further to explain to us, i am from India and feel blessed to learn from them.
Really really enjoy this physics talks, the humor and the positivism, and over the relentless need of humans for understanding the apparent simplicity of something as complex and beautiful as our universe. 😌👏👌👌👌
I only wish more people were driven into this fascinating topics and no into superficial matters. Maybe that we would have discovered what is time, what really is the Higgs fields and why it works that way???
This was one of the best WSF to date in my opinion. The standard model was exquisitely explained for laymen like me to easily understand on a basic enough level for me to have the confidence to explain it to others
What you call me

Very Very Very Good discussion, and in no small ways its because of how Prof Greene moderated the discussion!!! 👍👍👍👍👍👍👍👍❤❤❤❤❤❤❤❤
Wow what a moderator!!! Brian was out of this world good!! What an amazing group of people to be on stage together! Everything was to the point! Thanks 🙏🏼
He’s especially gifted at making things that are typically not accessible very accessible to people who haven’t spent years studying them. He’s truly an ambassador of science!
Brian, great job and many thanks in presenting the public knowledge in this scientific forum.
This discussion was incredible!
8:48 Democritus isn't overcredited at all, because he fully deserves his credit. He reached this hypothesis by logic and rational arguments, which is a must if someone wants to be called a scientist. The "atomon" he perceived as the fundamental non-divisible particle that all matter consists of, is actually the quark. That he was this accurate thousands of years ago, should make us appreciate his mind's creativity and vision, and not minimize his contribution to science.
I love seeing physicists eaten up with experimental angst. It means they have integrity.
Thats actually science, yes. If you enter an unknown room you gotta fear what coming, or that it was empty and yiu "wasted" a lot. But its the only way to find new things. Sadly lots of corparate financed and " career driven" University chairs are only playing the safe game anymore. The problem is things get so complicated you need resources, Hard to come up with things yourself while having a normal day job to pay the Bills like Einstein.
Exactly! Politicians are never eaten up by anxiety over facts.
It's wonderful to see these physicists together in this format. I watched Particle Fever dozens of times
It's like one on one education. Excellent source of user friendly information. Thank You Brian Greene.
Nima is incredible. When he talks I feel like he is supercharging my brain with info. When he stops talking, I the whole world suddenly goes into slow motion.
Brian Greene is my all-time favorite physics communicator/educator!
First time learning about Nima Arkani. I really appreciate him going out of his way and explaining the Bossom and other particles in such great detail. I'm barely begging my journey into the study if physics and he was able too grab my attention which is not an easy thing to do. I hope I can meet him one day and pick his brain.
What a day to watch this... Its coincidentally nima's birthday today!!
This is one of WSF/Greene’s best, and that’s saying something
Fascinating chat. I just am so intrigued by particle physics. Love it. The participants assembled here couldn't have been a better choice. They are gifted in their work and their ability to explain their work. Some of these festival videos are too short. I wanna listen to them all night.
i don't have any diploma in physics or whatsoever, but why do I find myself watching physics stuff? astrophysics, quantum physics... etc... am i a nerd?
Yep, sorry. But don't worry. There's a support group. We meet at the library. By ourselves, avoiding eye contact.
@@dustinfrost2603 Well, I'm alone in my world so...
Why would you be worried about being a nerd ? We are interested in science and it is wonderful thing . I do not have such diploma and very bad in Mathematics but love science and watch such things . Science is great and thanks to nerds we go to doctors if sick or can listen to the radio while driving a car and know that planet Earth is round :)
@@user-jy1xr1nh8s I guess you're right sir.
Maybe you're not a nerd, maybe you just have a great curiosity in how the world and the universe works.
thanks for such a grate conversion which simplify lot of our understanding
I couldn’t understand a single sentence in the entire show, yet found it super interesting. There’s another mystery!
You gotta build up to this with some background but I totally recommend you keep going
Brian's WSF is always interesting, always fascinating, and always informative. You can't ask for more than that.
you are so right in this. sad physical revolution take so long time, every 50 year maybe if were are very blessed
@@anttumurikka8728 I agree. As a (semi-retired) university psychology professor here in Canada, I live to see new breakthroughs in both my own field of psychology and in physics. I only hope that I live long enough to see the next big development in physics. While I have no regrets about going into psychology so many years ago, I am absolutely fascinated by particle physics and cosmology.
I LOATHE BRIAN GREENE - please give us ANY other host and stop making us endure his fucking EGO.
@@thinkfloyd2594 well fuck off then, you're a troll.
That was an amazing talk. Awesome casting. This is my third time watching it. There's no comparison between the 'in person' forums vs virtual. In person has it hands down. I hope for more of the in person forums in the future.
This is a great conversation. All four are very articulate physicists.

@@ivanpetrov8957 I've been thinking the same thing. And, yes, JRE goes there.
ok
I love absorbing all this new knowledge!
I can't help thinking about, as a bachelor with no kids, what you see of Peter Higgs' emotional reaction here, in a physics research presentation. On July 4th, 2012, the confirmation of the existence of the "Higgs' field". A field suffusing space, from which they knocked out a particle after 48 years of intense applied physics research and experimentation.
For my part, It looks no different from a new Dad at the moment of birth of his first daughter, or his first son. There's **only one** 'first time' for any occasion... 5:33
Thanks for reminding that science collects ideas over time and adds to the collective resources of the humanity not just mind :)
Thank you for this very stimulating seminar. All of your panel members were excellent. I am a psychoanalyst/psychiatrist and it is very exciting to see all of these brilliant minds working constructively during this major transition time culturally in human society where structural changes are occurring that result in serious mental health consequences impacting the functional integrity of individual humans of ALL ages. YES, all knowledge is the product of our brain meaning of the human BODY as a the brain mediates all human functions. The Hellenic saying translated into: "A Healthy Mind in a Healthy Body" remains the key. Grateful that the Covit-19 made it possible for me to have the time to see a lot of the great work of the WSF on UA-cam, instead of driving in traffic...MTL
You mean grateful for the fake co v
can we please just have brian host all of the world science festivals from now on
?
If he hosts them all he'll end up with his feet so far apart he'll look like he's on horseback
Agreed !! , I hate all the other hosts
These guys are tearing down the very curtain of reality , who knows how many layers will the humanity will be able to tear down till I live. Thankyou from behalf of our consciousness.
Wow. Doctor thank you so much. I was watching a documentary. Then fell asleep.
This video came on. And in my dream you were at my house around the dinner table doing the lecture. Kind of a round table discussion and physics talk. I was right there in it. Plus all the guests and other students. What a dream. There were props and back and forth discussion. Explanations. Gosh. Loved it. Went all the way thru this docu video and into the next one. A Q&A discussion with you also. Thanks.
Now I'm going back and watching both while fully awake on coffee. What a trip, "the implaton field!" Wut....
it was extraordinary! really enjoyed the discussion!
We're all just entangled perturbations, vibrations of a bunch of cosmic quantum fields man. Sounds like something I would have expected to hear from a hippy tripping on acid in the 60s. Reality's just laughing at us.
So fucking true hey
Boy. Do I want ya ta see a blossom bosom coming off the my betz breaker heck ya magnetic light speed 24x7 torque endlessly
That is very true
Only reason e €£ some tone of discernment outta be not so why
Min 46:30 Nima is absolutely brilliant in his explanation of why the Higgs is a big deal. I think he means "extrapolate" and not "interpolate" massive particles into massless ones, though. He is also excellent at 1:12:00 about the Higgs being or not being point-like. Very exciting. Let's build the 100-Tev!
I’m so glad to be welcomed to the precipice of human understanding with this discussion .So fortunate to be born in this time ..extraordinary.😮
Just watched it and i have one thing to say: WOW!
Being able to actually "view" duality is pretty cool when you get to observe it.
A great pod. I spent 3 months in hospital. No family and I a bad space. FPL helped me for sure but maybe stopped my social experiences in many ways. Thank you for sharing
Thrilling and magical. What an amazing presentation and wonderfully chaired.
Nima Arkani-Hamed is possibly the closest thing we have today to Richard Feynman. Unlike Science popularisers such as Brian Green, Nima doesn't dumb things down using analogies. Nima's descriptions reveal a deep insight into the laws of nature.
Remarkable. One of the best WSF presentations I’ve seen over the years.
Brian is such a genius.. He's a rare one
This is the VERY BEST YOU CAN GET TO LEARN THE BASICS OF WHAT THINGS (SELF) ARE MADE OF! WONDERFUL!
Nima was excellent! Favourite WSF to date. Brilliant.
And he sure gave that swivel chair a workout. I'm hoping they ditch the rug and add wheels next time around :)
To each their own I guess, I thought he was awful at this. Don't get me wrong his enthusiasm is charming and I know he is incredibly talented. I thoroughly enjoyed the Particle Fever documentary but this type of format with no editing, I thought he was terrible at. He couldn't even answer the yes or no question with a yes or no.
Always appreciate Nima's enthusiasm for the subject.
RadixSortable
Nima is an Iranian child to both physicist parents
Nima was brilliant, made me see exactly what the higgs particle represented, and why it was fundemantal to bridge the gap between massless/mass particles
fascinating conversation , thanks
Thank you a lot for bringing this very(!) interesting information, in such a fun and easy to understand way! Great! Keep on going guys ;-)
That was a marvellous session. Most enjoyable Nima Arkani-Hamed is amazing at explaining the difficult concepts so that a septuagenarian with only some limited mathematical knowledge, like me, can grasp the joy of the concepts! His other lectures are really worth a look. Brian Greene is a treasure for his genious not only in physics but also in being able to bring these wonderful minds together. The way he directs the conversations and explains, in more lay terms without in any way dominating proceedings is also a touch of genious.
I can't get over how good the audio is in these productions.
Wow, such a great talk
Great channel! Brian Greene is amassing!
Fabulous show, mentally accelerating!
Wonderful ! Thankyou for this.
Just... PERFECT
You know someone is a good teacher if everyone's just sitting and listening.
I loved it we need people like this
This Nima guy is very energetic :D
Annoying AF!
This was one of the best talks ever! And I believe it is a good thing that things are not coming along exactly how we expect them cuz it could be that a true revolution is right around the corner!
...or not, but agree thats actually science and Exploration. Nothing wastes more in the end though than " playing it safe" and not try to disprove things until you find sonething.
Absolutely brilliant.....
From the beginning of time when we first started looking up to looking down on the earth we wanted a conclusive explanation of how we would be able to make a difference between the ages of our society and our society has become so important in making sure we strive for a better future.
Great presentation by Brian Greene, concise and mind boggling. Nima Arkani Hamed was amazing, Joe Lykken and Monica Dunford as well extremely impressive in their inputs. I wonder about the source of "intellegence" that drives all these minds!
Science is incredibly good at telling us how, but when we think about 'why' we are led to ponder purpose and teleology. Science can't answer either.
I believe the discussion of the initial rejection of Higgs' paper is revisionist history. The paper wasn't rejected because it was "too wild." It was rejected because it was the fashion among the physics community to describe perturbations of quantum fields as "particles" and Higgs' paper was only in terms of the new field. He was explicitly told that the paper had been rejected because he hadn't mentioned a particle, so he added a paragraph that mentioned a particle and resubmitted the paper, and it was then approved for publication. But strictly speaking, particles are unnecessary and are misleading mental baggage from the early days of physics, and Higgs knew that. Fields are all that's needed, so lets apply Occam's razor and stop talking about particles.
I disagree with that. Perhaps I'm wrong. But I have strong mathematical and a physical reason to believe that.
Sure from a mathematical perspective if one develops a QFT (along the axioms) all one needs is the quantum fields. But:
QFT is an incomplete theory. The objective basis of a collapse is not described. And that is a transition from a more field like behaviour to a more classical particle like behaviour what's missing. This is the reason most conservation laws like the ones for energy are distinguished by the stronger conservation laws of Casimir Operators (like spin, charge and rest mass of particles - at least if we ignore the cosmological constant). Because for example energy is only in the approximate dynamics conserved in the pure states (and only a fair game in the mixed state dynamics) but Casimir Operators are conserved overall even in the not approximate pure state dynamics.
In QFT we work with one system of axioms. It turns out that it is not the most fundamental one (but the historical one and the mathematics is more familiar to physicists). And other axiom systems (especially the more natural formulations but mathematically more difficult to work with) do not need fields at all. From a mathematical perspective what the underlying principal is, are the particles (in QFT derived from fields). So fields are unphysical (one can get rid of them entirely) but particles are not.
By deriving a concrete QFT model like the standard model, at first one has to derive the free QFTs. And here the notion of particles is key (not the notion of fields). Otherwise you will not get from first principles to the allowed possiblity of QFTs. And such a simple derivation is key by Ockham's razor. And even from a practical standpoint, we are using the wrong free particles at the moment in the standard model from the standpoint of cosmology (because the Poincaré group - from which we get the particles from - is not even a universal approximate symmetry). By correcting this it is not clear that a field-theoretic-interpretation is possible again.
Totally wrong. All experiments detects PARTICLES. it is the field that is the mathematical baggage and can be removed from the formalism.
@@tofu-munchingCoalition.ofChaos can i interpret this as particles are the more fundamental existence while fields are more of an emergent property that help us mathematically understand how particles interact with each other?
@@rayxu1163
I would essentially agree with that.
You can at the moment always get rid of the fields if you like. But particle-like behaviour is an experimental fact you can not get rid of (even the name "quantum..." suggests that).
At the moment QFTs are built by quantisation (2. quantisation) of classical field theories (which in turn came from a quantisation of classical particles). After the quantisation the fields are no longer states but observables which help to describe the state.
Practically speaking is that many quantum particles (for example photons) behave in first approximation like classical fields ( *removing one layer of quantisation - the second quantisation* ). Looking more closely ( *removing both quantisations* ) a single quantum particle behaves like a classical particle in first approximation (for example electrons in classical electromagnetic fields - in this case we have not looked closely at the electromagnetic field, but looking more closely, like in the photoelectric effect, we conclude that the electromagnetic field is made out of photons).
So the fields are emergent middle level phenomenons. Like we often think of matter as a continuous mass distribution instead of a large collection of atoms. But even in QFT the fields are not the states (real physical reality) but operators used to describe the states.
At the moment we are not able to describe the quantum particles precisely. We know how quantum particles (approximately at least) behave at the quantum scale. And we know how a quantum particle behaves when interacting with a classical measurement device. But these two descriptions are incompatible at the moment. This is known as the measurement problem in quantum physics ("collapse of the wave function"). It is not resolved yet.
One important (but not all) particle-like behaviour comes from this collapse of the wave function which is not worked out. I suspect that this (together with the practical derivation of QFTs from Lagrangians of classical fields) is the reasons people think that fields are more fundamental. But they are in my opinion wrong on a mathematical basis (how it came about from first principles) and ignore the precise physical underlying basis (states and collapse).
Poincaré-Birkhoff Theorem that’s a very interesting point of view. I always think of fields as being a “dual existence” (not physical reality existence) to the particle form of existence. I didn’t notice this until your comment mentioned it that the “particle” way of describing these little energy packets and the quantum fields way of describing them are actually more conflicting to think about than I realized. I am currently only doing mathematics as undergrad so I don’t think I can give a validated opinion on which one of the two is the more fundamental existence. The QFT if I remember correctly does suggest that fields are the underlying phenomenon and that they are more fundamental. But again as you argued the QFT is not a complete theory just yet so it can still go either way.
That was still some excellent sharing nonetheless and I’m pretty sure different ideas is what will motivate people to dive even deeper into these questions.
Nima appears to have a massive amount of potential energy. Great video.
watching his movements when other speak and his hands when he speaks, he actually has massive kinetic and not potential energy.
"Yes or no answer."
Nima speaks for 10 minutes.
I was pulling my hair out.
Brian: "I'm looking for a yes or no answer"
Nima: Six minutes and still talking...
Brian interrupting: "So just to give a quick summary"

Its awsome short and sweet and unexplained yet .might be a wormhole baby.and reproduceable it overturns betz limits for sure.
scientists ? Or pupputeerrd
The electron does almost all the work, but it's the proton that gets the credit for everything. The neutron just sits around and collects mass. That's not fair! The electrons deserve more mass for what they do for the universe!
Greene used to annoy me, and now I can't get enough of him!
Imagine being Higgs right there. All of that work finding out how the UNIVERSE works, and you were right.
Are you so sure they couldn't start with different premise and end up tweaking it and make it work as well? String or loop theories - so outlandish - yet they nearly work + it beats standard model in few fields. The true can be completely different - and who knows - it may takes another 2000 years to come to it.
I too was heartened to see Higgs' reaction. Had a great physics teacher in high school. We spent one quarter proving a theory. At the end of the quarter, we were shown a film about the life of the person who discovered the theory. The film portrayed that person on their death bed discovering irrefutable proof that the theory was wrong. I'll never forget the shock and pain we felt for that person. incidentally, one of his later students was part of the discovery of the Higgs at the LHC. My teacher's son was a very good friend. He told me that his father actually had a Ph.D. in physics and turned down both a research position with G.E. (for very substantial money), and a Department Chairmanship at the University of Nebraska to teach high school physics. A very special teacher indeed!
I understand this stuff, wow!
i know...cool huh ( :
I think we have to stick to the notion of ether as of now... Thanks for the priceless knowledge shared.
