There needs to be a bifurcation in PhD-level physics education between foundations and applications. Shut-up-and-calculate physicists don't need to know much philosophy because they're really just glorified engineers. They're not supposed to think outside of the box, they're just trying to describe the box because it's an insanely complicated box. Students of the foundations need to know different ways of thinking, different ontologies, the history and dynamics of theoretical research, and anything else that will help them break out of the current mindset and discover the next one.

@jeffreyharrison3731 Год назад
I think the views of Becker and Maudlin align rather well with the interpretation of the history of QM. I think both of them would agree that non-locality was a bigger issue for Einstein than hidden variables, And I think both point out that Bohm's pilot wave theory was deterministic and non-local - refuting Van Neumann. They might have different affinities toward String Theory, MWI, and operational collapse, however.

It's one of the most meaningful lectures I have ever listened. I'm reading Adam's book and this lecture was a good complementary for me to understand quantum physics better. Today, as I was cycling in the desert, an idea came to my mind. If there are at least two states for Schrodinger car, one dead and one alive, the whole nature that I saw today as I was cycling could be in infinite other states among which one is perceivable to me!! Because the wave function underlies the whole universe.

@37:48 Becker: "Then [Bell] says... there's something else funny about Bohm's version of quantum physics. It has this spooky action at a distance. The position of a particle way over here can instantaneously affect the behavior of a pilot wave way over here." This is a mischaracterization of both Bohmian Mechanics and of Bell's commentary. As Becker explained earlier, in BM, pilot waves guide the movements of particles. However, there is no mechanism by which a particle's position can influence the behavior of its pilot wave, instantaneously or not. The pilot wave that guides the motion of the particle is not "over here" (i.e. separated by some physical distance). Pilot waves do not propagate across physical space-time, they manifest solely in Configuation Space, the complex-valued domain of potentially limitless numbers of dimensions where the quantum wave-function is defined. Becker then shifts gears into philosophical musings, and in doing so, short changes Bohm almost as much as did promoters of the Copenhagen Interpretation. What Becker glossed over was the main conclusion of Von Neumann's erroneous proof: the claim that quantum mechanics rules out ALL hidden variable theories, such as Bohmian Mechanics. What Bell discovered was that it is only LOCAL hidden variable theories that are ruled out, but NOT the non-local Pilot Wave theory of Bohm. Bell's Theorem actually vindicates Bohmian Mechanics, as did the recent Nobel Prize-winning experiments that confirmed Bell's predictions. Becker's historical account of quantum mechanics is nevertheless quite compelling. What happened next was even more provocative: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TvDCMS9bk74.html

If you can't get completeness and consistency in formal systems powerful enough to produce Peano arithmetic), then how can you get it in physics? Hawkings invoked Godel's theorem to argue that a complete and consistent TOE may not be possible, for example, but I am unaware if the Incompleteness theorem can be applied to the measurement problem, however.
@jeffreyharrison3731
@jeffreyharrison3731 Год назад
Great talk, Adam. Thank you. Objective collapse theories that invoke gravity for objective state collapse of superposition like the Diosi-Penrose (DP model) are not holding up well under experimental conditions. I guess just the essentially irrefutable interpretations like Copenhagen and MWI are still in play. Perhaps modern physicists should employ Newton's famous words: Hypotheses non fingo.

BTW, I think is better avoid the "explanation": "a single photon will interfere with itself", a la Wheeler!, not to keep the misleading. Very good talk, I am personally very interested in THIS history, but as a Tim Maudlin follower, I would like these popularizations had a correct and precise language! Go on! It is "necessary" more people know about this history

Evolutionary Psychollogy has done more for the understanding of human nature in 30 years than philosophy in 2000 years. What are you talking about????? I loved your talk. I've shared it. And then... you say that about Evolutionary Psychology. Disconcerting! It is just darwinian evolution applied to the mind with the help of game theory and computer modeling (which has also been key in understanding plain evolutionary biology). What is your intuition about why that approach could be anything but brilliant? Did Richard Dawins do something to you?

In order to understand better, you need to learn the theory of entropy chaos and order. The physical world (sensorial) is what we studied believing as real. But what is really making these sensitive world is quantum which is random, unobservable, unmeasurable with our consciousness or any mechanic device we could probably create. That chaos, randomness is expanding energy and that is what’s real. We animals are made of it and affected by it as a part of an ecosystem. Awareness beyond sensorial data collection which means trespassing the nervous and endocrine system can help the observation and its effect, but can never be completely controlled, if so will create a new behavior and that can be destructive. Remember it’s all about data collection and storage, our dna is our Cloud connected to the super cloud. We can “download” data and manifest with awareness of pure gray matter. That makes some humans more powerful than others, because they know the coding of the proper frequencies and vibration. Mistics

I am That, you are That, all this (everything0 is That pure Consciousness. However, logic along won't get you there. One must use specific techniques (many invented by the ancient Buddhists and Hindus), for tapping into and merging with Consciousness. This requires the direct non-dual apprehension of C. in a state that transcends the mind. What collapses wave functions? The entire universe collapses every wave function.

When comparing physicists and philosophers of physics the imbalance is not in the due diligence of the professions as suggested but in the structure of the question being asked. Philosophy of physics is by definition an interdisciplinarian profession and a subset of philosophy, physics is a specialization and an entire field, not a subset. It's more fair to compare all physicists to all philosophers, in which case the imbalance disappears as almost all philosophers know squat about physics. You may ask why physics does not have a subdiscipline devoted to the intersection it shares with philosophy, as philosophy does, but I don't think you'll find many people signing up to study the physics of philosophy. Essentially, physics is in the scope of philosophy, but philosophy is not in the scope of physics.

My understanding is that the Copenhagen interpretation denies mearurement (observer) independent reality to particles (the world). So, one way to get around the measurement problem is to deny realism, or observer dependent reality. The title is questioning reality its self as we know it.

I couldn't watch the video, had to go audio-only for most of it. The incessant "weebling" by Becker makes him almost impossible to watch without becoming nauseous. I find most physicists can describe all there need be said about "what is real" from the perspective of quantum mechanics in a brief paper or a talk you can fit into a TED timeslot with moments to spare. But since non-professionals don't buy brief papers, they buy books instead, authors have to pad and pad and pad. Ugh. Nonetheless, Becker has a genuine quality that one can't help but find appealing. But when he showed his admiration for the multiverse, I made a decision about whether to read his book.

Mr. Adam Becker is a popularity seeker who takes is scientific divagations as established facts, one can have a PhD in physics and still misuse is knowledge. However - if the human mind can imagine something, ultimately given the time and the opportunity it will accomplish it. By assuming that the majority of people does not understand quantum mechanics, Mr. Becker endeavors to arrogantly illuminate the masses to is unreliable and yet up to scientific debate opinions on the subject. I believe that people should deeply research the many articles published on the subject and come up with their own conclusions. Personally I take offense at such display of fat theories and very lean assumptions of facts. Misinformation and controversial ideas are excellent means of challenging the scientific status quo, thought it should really be first discussed and argued within the scientific community.
@GOffUnit
@GOffUnit 5 лет назад
His book, though still scientific, is more history and philosophy than science. If someone wants to dive deeper into experimental physics then this is not the book for them but, in my opinion, this is still a great and valuable book. This book is a challenge to Feynman's notion that "if you think you understand quantum physics, you don't understand quantum physics," and it's made persuasively. Becker shows that despite what the popular historical narrative tells us, quantum mechanics was not all but settled before WWII, and that there is still much left to discover about it. Further, it's a source of encouragement for any aspiring physicists out there who share his unease about the present state of quantum physics and believe we can do better.
