V=52/m/s(terminal velocity of free falling objects) M= nonrelevant g =9.81m/s^2 Calculate h = 137.81m Thats the free space h underneath plane impact location that is needed for the upper tower part to reach free fall speed. But underneath the impact locations In the Towers there was no free space. There were 40 floors who should have resisted free fall. How did this magic trick happen celebrity physists ?????????

I literally just commented about how AI logicians should be working with these particle teams. funny, right?

So yeah, I am a member of LHCb at CERN, I have been doing this for more than a decade and what she said in the video is 100% true. People at LHCb know it, they do not like it, feel embarrassed about it but their only choice is to just keep doing it or find a job elsewhere. For instance, we had a collaboration wide meeting a few months ago and Sabine was ridiculed by the Physics coordinator. Were there arguments? No, just plain mockery and it was endorsed by senior people, not students or postdocs, but faculty. I frankly would have expected either to have a discussion with Sabine, if the disagreement is so important and they care that much about Sabine's videos; or just ignore her, if they believe she's a crackpot. But mockery? That should be beneath our community. I felt deeply disappointed to see our community falling so low. When I started in the field I thought scientists were objective, data driven and open. No, they are tribal, sensitive and when they feel attacked that group mentality emerges. Do you remember the B meson anomaly that went away? Well, we cannot use the word "mistake", we have to talk about the new result "superseding" the old one, no one really wants to recognize mistakes here. One faculty from ATLAS used the word "mistake" in the seminar about the B meson anomaly that went away and immediately the LHCb physics coordinator (yes, the same one from whom the mockery mentioned above came from) reacted trying to keep LHCb safe. For all those people wanting to go into science because it is full of nice people who are only interested on science, the truth, etc Think twice, there is politics here too, I guess not unlike industry; you just make less money and have a short term contract, unless you are tenured. And that's why I am not posting with my real name, I am not going to expose myself to oversensitive angry colleagues.

Philosophy of anything should not be required as part of science curriculum.

As a theoretical physics myself (complex system) that used to work in a department very famous for Particle Physics, I have to say that I fully understand Sabine but also Particle Physicists. It is not easy to be trained to understand and fix a refined and beautiful model - the greatest human achievement of all time - and, after finishing 10 years of specific training and getting a PhD, finding that the model works and there is nothing much left to do. Everything in our energy range has been understood, and we already made efforts to go 5-6 order of magnitudes more in the experimental range to find the missing parts (Higgs). A slow transition to a world with less particle physicists will be needed, but I understand why they keep trying to understand more of it, a last hit or miss to chisel their name in the model, to say "I am also part of the greatest human wonder, I was just born 10 years too late!"

In my work I got frustrated by the amazing amount of politics and management going on, having to pay to get published and if you didn't have 10 papers, you were a loser. Many get their PhD because it's required for a job later on, etc. All of which have nothing to do with science and in my opinion degrade it.

Here whining about particle physics always brings out others who complain. She herself is working on theories on DM and superdeterminism that are most probably dead ends. But that does not stop her from pointing at others who might be involved in the same dead end researches. Her own dead end research should have taught her a good lesson but maybe the publicity she gets is good enough for her.

This video cemented one of the reasons why after my PhD I didn't dare do a post-doc or go further into academic research.

Very well put, and thank you! I'm not a scientist myself, and have only recently retired from a career of repairing cars, but the foundations of physics has always been a fascinating thing to me. Now with some time on my hands I can learn a bit, and it really helps to have someone rather unmercifully separating the wheat from the chaff. There seems to be a lot of chaff. I'd also add, as a mechanic, I always emphasized to the new guys how mistakes are inevitable, and machines don't care at all how confident or enthusiastic or certain you are that you are right. You either get it right or you don't. If you get it wrong as a mechanic, you need to explain to a customer how you wasted their money but you'd like another chance. Some guys never really get that part; honesty can be hard, and admitting you were wrong is hard. That's one thing I always looked at in trainees - how they dealt with their own mistakes. I haven't "lost faith in science" or anything like that, but I could judge a lot of particle physicists based on those terms, I guess. Not that I could do better, but I was a good mechanic: whenever I made a mistake or was wrong about something I'd talk about it with everyone, so they didn't make the same mistake themselves. If you ever hung out in the break room of a good shop, most of the best stories are guys talking about mistakes they made. I wonder if there is a string theorist's break room somewhere, and what kinds of stories they tell...

Back when I was in particle physics 20 years ago, shortly before a talk on super symmetry, the video projector wasn't connected to the speakers laptop yet, so it just said "no signal". That one super symmetry-sceptical experimentalist professor enters the room, checks the screen and goes, "Oh, the conclusion already?" We students had a great laugh. The theoretical physicists, not so much.

Hi Sabine, My guess is that the reason for what you describe is due to the fact that universities put tremendous pressure on professors to publish. Coming up with good solid experiments is difficult. But, coming up with those experiments where over fitting is typically the result, is much easier. Thus you get 50 years of crappy experiments and papers that don’t end up proving anything. But they served a purpose. And that was to check a box for a professor to publish something that year.

@diegog1853

Жыл бұрын

Honestly... I don't think that is necessarily wrong. Publishing a good paper is extremely difficult, and at this point in time in our current system. Publishing papers is synonymous with doing research, is sometimes the only way to get paid for it, or to get government funding. So if we increase the bar for what it means for a paper to be good. Then you will inevitably just erase a good amount of researchers. Sure some of them would get inspired to be better and write better, but others won't keep up and just abandon research all together to just teach. And I think that is ultimately unhelpful, we need more researchers, not less, we need more funding for science, specially in developing countries. In a way, lousy papers are just something to keep your university professors occupied and up to date. Even if they publish bad papers, they are up to date experts on their field, and that is valuable. I think in general, this is more a symptom of a bigger problem, which is we putting so much value on the publication of scientific papers. That is kind of the ugly underground mafie-like side of science that not too many people know about. Scientists publishing multiple papers on the same topic just explained differently, citing their own papers multiple times and the papers of their friends. I don't blame them honestly, that is just the system, like the grind, click bait and collaborations a youtuber creator might have to do to be succesful.

The sad thing is, you look at some of the foundational papers that are forever-cited in their fields, and it feels like they were all written by people who only bothered to publish a handful of papers. There was a time when scientists were given the space to tackle difficult problems over many years and avoided polluting the space with fluff, thereby reducing the signal to noise ratio for other scientists. I went the professional route and abandoned academia because of my experience with the politics of research and publishing like clockwork. Ran into a lot of essentially made-up papers like the ones described here, and felt tremendous pressure to "see publishable results" in something that really could only be published as "well, our hypothesis was incorrect - don't bother wasting your time over here".

Actually, Universities put tremendous pressure on professors and staff to obtain grants, which the university then administers, for a fee. The universities actually want professors to be self supporting through generating grant money, then the university has more money to pay executives and administration, as well as building physical plant. This results in universities going to tremendous expense to recruit professors and researchers who are already well established in their field, and are already generating large amounts of grant money, or may have large grants whicgh they can transfer from another institution. What Sabine is describing however is more like the medieval professors debating how many angels can be on the head of a pin, a question which doesn’t have anything at all to do with science. Particle physics has turned into something with close resemblance to religion.

I am so impressed by the way you convey information. Very professional, and also the pace is excellent.

Excellent, though challenging, presentation. I got my PhD in physics back in 1986 but didn't have the theory chops for particle physics (though Steven Weinberg was one of my professors). What I really regret was not joining the LIGO gravity wave experiment...now that was possibly the last beautiful experiment we will see for a long, long time. Though I'm not up on the latest particle theories and experimental results, Sabine offers a persuasive (to me) argument that the field is floundering. It's a shame.

It reminds me about the story of Johannes Kepler who, until the end of his life, kept trying to fit the orbits of the six known planets into the ratios of the sizes of nested platonic solids. Even though he was the guy who figured out that the orbits are elliptical, he still felt his platonic solid theory was the true underlying structure of the orbits.

Reality is an information process, set in motion and sustained by God for a purpose. Understanding the purpose is more important than knowing anything about it. After one understands the purpose, knowing how Reality works is important. The continued growth and development of humanity depends on it. From this perspective what particle physicists are doing is similar to analyzing the Mandelbrot set, trying to develop math that describes it.

You are brilliant ma'am. Truly I can't overstate what a transformative influence you've had on me. How you manage to use wit, sarcasm, logic, facts and humour to create credible scientific narratives with universal acceptability in its common sense, this to someone like me - with no background in physics - being able to understand and appreciate these complicated theories, you ate my hero..it's incredible. Thank you, keep doing the good work, and it's true, science should always question and challenge dogmas. It appears like we some sections among the scientific community have retrogressed back to the age of ideology and belief. With people like you, I believe, there is still hope.

The problem with the video is that we know for a fact that Standard Model is WRONG. It predicts 0 neutrino mass, so there should be (almost certainly) no neutrino oscillations (but there are). SM doesn't work with gravity and that's a problem not because we want all forces to be describes by one neat equation (that would be great though), but because at least one of the theories has to be inconsistent in certain conditions. So, yes, we are not entirely sure where exactly to dig, but we know for a fact that there is physics beyond SM. That's why the search for the breaking point of SM is important - it is what we need to drag ourselves beyond SM.

I completely agree. I did my PhD in gravitational theory and found similar attitude problems in the camp of gravitation and cosmology. I always resisted getting in the bandwagon and it didn't do my career any favors. It feels kind of vindicating to see Sabine articulating so clearly what has been my fundamental intuition for a very long time.

Sabine, this was a great lecture. I am an engineer, not a scientist. I have long envied the mathematical sophistication of particle physicists, and I hate ignorance, especially my own. Once I was reading a popular treatment of string theory and M theory. The author did a good job of setting up the historical context of the research, and of recounting the achievements of the brilliant pioneers in the field. As long as the story was about people, it was a good read. When the author tried to make concrete statements about the theories, it fell apart. I set the book down when, three-quarters of the way through, it descended into gibberish. In the later chapters the author went on and on gushing about the wonderfulness of these theories while explaining that they couldn’t be falsified using any experimental technology we possess. Supposedly there are as many as 15 dimensions, most of which are too small, in some sense, to be examined. No workable experiments can be conceived that might test these theories. This is very unsatisfactory to me. I felt that the string theory enterprise had tipped over into metaphysics. As far as the dimensions in which we are actually able to run tests go, it occurred to me that if one devised an overarching theory that was sufficiently complex, one might explain, or rather model accurately without explaining, anything that might be observed. Such a theory would be an ideal vehicle for overfitting data, with impressive untestable ramifications for dimensions we can never see. That theory would be string theory or its other non-falsifiable successors. That being said, your discussion raises some practical questions. How are we to train particle physicists if the standard model is perfectly correct? Must all particle physicists become experimental ones, forever searching for some falsification of the orthodox theory so that the field of theoretical particle physics may be reopened? Who will be capable of acquiring the necessary mathematical acumen if no one is working in the field? Please consider the possibility that the field has reached a state analogous to the pre-Rutherford era when a bright young man was advised not to go into physics because everything important had already been discovered. This was just before the early evidence for quantum mechanics blew the doors off that understanding and opened up a new era of discovery. Finally, we must have people working in unifying quantum theory and relativity. Couldn’t theoretical particle physicists make a contribution to that effort? Perhaps some of that talent and energy could be usefully redirected.

I had a strong impression that the golden years of particle physics are over and something is going wrong but couldn't explain to myself what exactly was going wrong. Because funding was still good and papers were being published and detectors being built... but there was a kind of flaw in all this.

It's okay for a field to just run cold for a bit. But I think this is a great example of something trapped in its ways. Much of it is looking to re-capture the golden age bringing about a revolution instead of building forward. The Penta-Quark was discovered after the Higgs Boson. The muon g-2 experiment was still going forward. New neutrino studies were being made, but you probably are aware of some of the ego problems there. People are chasing a theory of everything, just as in AI people keep coming back to an artificial generalized intelligence, though I think the latter is more reachable. People said we would be there back in the 1950s. AI stuttered a lot until the 90s and 2000s again. Now it is running extremely hot and we see how complex it is, but people keep talking about the AGI when we clearly haven't fully figured out all of the essential intelligence components.

The most serious problem that derives from that is that if you play to extend a model artificially, since there can be infinite ways to extend it, it is very very easy for you to add complexity that explains the universe of particles in a fallacious way, far from Ockham's principle, and that is a deeply anti-scientific behavior. unsightly and harmful for having the potential to fool all future physicists for decades only to have to dismantle the last great extension of the Standard Model that came loaded with inventive and false sugar.

Great video. I was a graduate in particle physics and had the same thoughts, same doubts. Considering the amount of studying you have to commit to publish a decent paper, those who "survive" in the particle physics society are those who are mathematical nerds and those who doesn't have the time to pose these kind of questions. Because in the end it's the sum of published journals that you'll get a job anywhere in this field. Only if youtube and internet were as popular back then I could've also seek out people who had these same views to particle physics, but after thinking on my own I quit before getting a Ph.D. As a child, researching superstring theories was my dream job, now I don't regret having left this field. I turned my career to software engineering and A.I. which I think is a much more interesting subject. Who knows, that in the far future it would be faster to let generative A.I. to learn all the particle physics theories and then it could come up with a much more convincing theory.

He also drew attention to theories that need to complicate themselves in order to fit with observation. He observed that that, in general, this was unavoidable (we should not be too quick to refute) but that any such change is an ad hoc modification and theories that do this frequently are degenerate (A theory can also become degenerate if it ceases to make new interesting predictions).

Company coding standards exist to protect the next guy from your highly performant, but totally illegible, code when it breaks. Also, elegant code tends to be very simple- which is great, fewer points of failure. Debugging becomes simpler, and overall the code is just easier to conceptualize. Not to say that there isn't a place for inelegant but efficient code, math libraries for instance, but to say that's 'oftentimes' the best approach?

But we do not needs model. The objective is to solve stuff that does not work, or stuff that has not been found. I.e. my objective is that I wanna travel the universe in seconds, my current theory does not permit that, thus I try to find new theories that allow it.

Dr. Hossenfelder, thanks for this. I'm tired listening to the so-called " popularizers" of science talking about their "discovery" without empirical basis. I teach Kant in my literary criticism classes, i understand how his philosophy of science shapes our understanding of reality.

I feel your pain, though from a different perspective: In 1953, when I was 10 years old, my Bohemian single-mother's landlord was Frank Crawford, a physicist working on his doctorate at UC Berkeley. I have a vivid memory of Frank's excitement when he got wind of the work of Cowan and Reines: first hint of neutrino detection 1953; full report 1956. Frank introduced me to the periodic table; gave me a chemistry set; taught me algebra; took me on a tour of the brand-new Bevatron in 1954, etc. Those were incredibly exciting times. And although I went into a different field (Ph.D. in Chinese), I can sense the immense sea change in what particle physics is these days versus what it was back then, toward the end of its Golden Age. No comparison. (Some bibliographic notes: Wu et al Phys Review 105, 1957 [for my money, her demonstration that the universe has handedness marked the end of Golden Age of particle physics]; Crawford Phys Review 107, 1957 [follow-on to Wu 1957]; Crawford, WAVES -- Berkeley Physics Course Volume 3, 1965.)

Of course, the people that are designing the next big cool collider will not like this video.

This is complicated for me to understand, after all I am not a physicist. But I understand the basics and I think you are right. But there are big problems in physics that maybe need a new approach that maybe do not need a new particle. A big problem in physics is the lack of a quantum theory of gravity and the explanation for "dark matter", meaning "why the universe looks like it does"

Well that sums up very well my general feeling about particle physics. As a young master student I went for an internship in particle physics as I thought that was my dream job, and that’s where the best physicists would go (and who wouldn’t want to be among the best?). After spending time in the literature and talking to actual particle physicists I realized exactly all of that, and it didn’t fit with my view of what is good science (I mean compare a generic current particle physicist with, say, a Feynman…). Knowing that I had only little experience with experimental physics work (which otherwise would probably have been my first choice) my goal then became to slowly shift to maths, which at least has the advantage of being much more demanding in terms of level of proof, and, doesn’t require gigantic amounts of money to be wasted in gigantic experiments testing hypothesis which by design (!) will almost surely turn out to be wrong. Plus I can still look at physics inspired problems (a lot of what I do is related to complex systems, statistical physics and quantum information), so it’s for the best. The shame is that they are a few bright minds in particle physics and they’d certainly be much more useful for science or society working on other problems.

One problem is that in many institutions your performance is based on the number of publications, and it's certainly easier to just modify something theoretically than really discovering something new. I'll organize a conference, invite my colleagues from other institutions, publish the proceedings, and then my next friend will organize the conference next year, invite me, publish the proceedings, and so on and so forth.

The collider method is violence. The results of collision will likely be fragments of elementary particles rather than the elementary particles themselves. I’ve had some crude videos myself. If you have time to waste, please search play list: Physics, Nature’s Perspective. For example, I noticed that half-life uses a continuous concept to describe something finite and discrete, such as radioactive elements, which may have an odd number of atoms. Of course, it is the thinking pattern of modern physics, using continuous and even smooth concepts and methods, such as curvature and partial differential equations, to describe our finite and discrete universe.

The problem comes down to how modern academia works. New breakthroughs in fundamental physics are hard, especially after having exhausted the consequences of relativity and QM by the 70s. Despite this challenge, theoretical physicists are compelled to publish new research consistently in order to advance their careers. This, coupled with the fact that experimentalists are hungry to test new theories in order to justify their increasingly big and expensive devices like the LHC, results in one speculative theory after another with little basis in reality.

A good read on the subject of scientists becoming consumed with the chase to be relevant (and failing to maintain proper scientific rigor when their pet hypotheses are demonstrated to be incorrect) is _The Stars Are Not Enough_ by Joseph C. Hermanowicz. Like Feynman said, it doesn't matter how elegant, or beautiful the math is, it doesn't matter how much you like it, if it's wrong, it's _wrong._ Letting go of stuff like that is part of science. Particle physicists make whole piles of wrong predictions, because that's what scientists _do._ The point of the game isn't to figure out what's true, that's the emergent property of the game that we leverage to improve our understanding; the game is to show how you might be _wrong_ with your prediction, and you need to be serious in trying to do so.

I was going to fix particle physics--but then things got really busy at work.

Can't build a bigger collider without a good reason, can't find anything new without a bigger collider. I get the distinct feeling we're in a negative feedback loop of scientists grasping at straws for bigger toys looking for a breakthrough.

If I understood correctly, which maybe I didn't, Sabine said that we don't have to think about the structure of dark matter, it's 'details', only its gravitational effects. I don't think the structure of dark matter, if it exists, should, or could, be off limits. Finding anything that doesn't fit the standard model would be an immense discovery about the possibly other 85% if the universe. I would also have liked it if Sabine had addressed gravitons. Does she think them likely or unlikely and where they and any associated particles like maybe gravity bosons or 'quark-like' particles would fit in the standard model. I was also wondering about string theory but I see she has a video about that so that's next because I really like her work.

I enjoyed that. I'm not a physicist and work in telecoms / IT and we have similar problems with engineers. There are those that understand a problem and will produce a considered and relevant fix for that problem, and then there are the "poke and hope" people who invariably forget what the original problem was, make multiple changes without recording what they did and invariably make things much more complicated and very much worse. Much like the British Judiciary and legal system come to think of it..........

We threw the kitchen sink of experts at the problem, but at the end of it, we had not arrived at a root cause except suspecting but not confirming it was related to overheating or other environmental factors. Months later, after our testing was concluded, it turned out the failures were caused by cosmic background radiation. Their memory chips were impacted by the radiation, and they had to redesign them to include error correction.

The solution for your (and many others) problem start with focused data collection, and documentation of the problems, the solving decisions/actions, and results. If U've data, U can calculate effectiveness, find the holes in the system, implement the actually working solving methods to other fields, other people. U can inspire people to teach/learn methods from each other, and demand the good practice. (Internal trainings.) After that U can inspire to learn universal problem solving methods from the world by external consultants. There are many of them fitting for different type of business, or problems (5 Why, Ishikava, 8D...). Some of them are statistical, some of them are simply focusing, or gap based. U can implement it in your system, train your people, demand the follow, and measure the results, collect data. From the data if U can identify spots, where the most/longest/biggest problems occur, U have to focus there. Search for causes, risks, and try to minimize them. (Go back to point no.1.) In a professional company there's no such thing as human error. Every human error is coming from a deeper cause hiding somewhere in the company system. (Lack of skill, lack of training, lack of inspection, lack of control, lack of resources, lack of time, contradictory goals...) Poke and hope seems only effective, when U're not well prepared for (any) changes, or issues (which will be inevitable). I can suggest instead: collect data (focused!), analize them, and implement the results, so when the time will come U'll have something to work with. (Btw. every action is somewhere a poke and hope, because U can never take into account every possibilities, U never know everything, and U know that. So the difference is in the size of knowledge regards the problem, the own profession, and the problem solving, and result analizing methods.)

I believe that Popper's falsification concept led directly to Kuhn's paradigm shifts which described science as "good ideas being replaced with better ideas". Not "Good ideas being replaced by more complex ideas". It also occurs to me that in physics, the best ideas are (by far!) the simplest ones. And Newton was correct: when looking at the same stuff, there is no need to come up with a different explanation - which nicely distills down to Occam's Razor, and simplicity.

A friend of mine's wife is a theoretical physicist, one day while talking to her he found out that she didn't know that objects fall to the ground with the same acceleration. She was working with unimaginably complex mathematics but had no understanding of the basic physics of the actual physical world.

I was majoring physics, but caught the same problem you are talking, and I switched to applied math since. For me, math turns out to be a surprisingly concrete subject. It may often seem too abstract to be useful, but no direct physical correspondence (some algebraic structures for example) doesn't imply it's useless (e.g. cryptography). p.s. ofc physics still has a lot of interesting problems, but it's no longer finding first principles, and more like applying first principles to physical systems.

I'm a retired electronics engineer (not a physicist), but I've been interested in particle physics all my life. Since I was in my 30's however, I've suspected what you've described has been going on (i.e. the profession is really a "keep the money flowing" operation). They get everyone hooked on a new theory (along with its intricate and exciting storyline) and go to town with it, suspecting all along (or worse yet, knowing) that it's just fantasy hocus pocus. And then, when they run out of plot twists (and any confirmable test results), they move on and hatch a new story. Or, they proclaim they've found the "smoking gun", which later proves to be debatable, but keeps things going for another decade. They go on and on about things that don't seem credible, that they can't and will never be able to prove or observe, spinning stories for how things must work and where they're sure they'll find proof. But then, the stories turn out to be dead ends that never could have been true and/or never had any validity or basis in fact ... and then they eventually move on to the next lame theory that's as goofy and convoluted as the last. I've come to realize that particle physics has become a great occupation for many meritless pseudo intellectuals who would've likely made livings as con men and snake oil salesmen in another era. That seems to be the direction things have taken in my lifetime.

Hi Sabine, great video as always! I received my master's in particle physics last year and started a PhD working with the CMS collaboration last fall, and I definitely feel like an outlier for sharing the majority of your views (I was one of two out of ~250 people at a conference last year who dared to mention that we found the physics case for building the FCC to be flimsy at best, for example). It seems that most of the grievances you mention focus on theorists rather than experimentalists (understandable considering your own background), and I would add that the problem is worse than portrayed here because those claiming "it's falsifiable" are likely the minority, with many others working on models that have no chance of being verified/falsified in the foreseeable future-hence anyone claiming that their model is falsifiable believing that they're "one of the good ones." I'd be curious to hear your thoughts on the problems in experimental HEP, and if you have any advice for someone just starting out in the field on what we can do to try pushing ourselves back on track.

Every project needs a devil's advocate. Paradoxically, larger teams often have a harder time spotting structural problems, because people are less likely to speak out. I'd maybe push (discreetly) for pre-mortem style project-management exercises where people are given the job to find cracks in the status-quo ("hey Prof, I heard about this project management exercise, do you think it would be valuable for us?"). I can't stress enough though how important it is to be very, very diplomatic about how you approach this kind of thing. Be collaborative, not confrontational. Egos are a thing and rigid minds perceive devil's advocacy as incessant naysaying at best, active sabotage at worst.

Thank you very much for the excellent talk (and sharp critism). As a graduate student working on cosmology, I think your responds to the dark matter problem is not exact. I used to work in a group of weak gravitational lensing, which measures the distribution of dark matters directly. But we do not think that the distribution of dark matter and the nature of dark matter (I mean, lagrangian of dark matter particles) are two distinct problem. In fact, from cosmological simulation, how dark matter particles or objects behave do affect many OBSERVABLE properties of the structures in the unverse. For example, hot dark matter (such as neutrino) will form much smoother structures, which is ruled out by observation.

Actually, it's not. Unification is not a requirement of science. It's an imaginary intellectual goal, but there is nothing in the definition of science that requires it. Science only requires that theories reproduce observations. There has, so far, been no observation of quantum gravity effects.

The moment you brought up a lot of data points and mentioned having a lot of assumptions with it, and adding more just so it FITS what you want it to fit, you reminded me of one of the most important things I've learnt from one of the best professors I've had: the law of parsimony.

Yep, it is good. Funny thing is, I read the book before finding her channel. I feel kinda dumb that it took me awhile to realize they're the same person.

"The Higgs Fake" is also a good one. Written by another German dissident.

14:00 haha I’m not a particle physicist but this pseudo-problem phenomenon has been a terrible habit of mine I’ve applied to way too many things. Fantastic work on this video! It’s incredible how clear and concise you’ve broken down this topic and it’s trend of asymmetrical practices.

I see this, and have been guilty of this, in work environments all the time. We call it busywork, and some people use it as a means of pretending it'll lead to long term job security

Perhaps, human nature implies creating pseudo-problems. Since that's psychology, I'm not going to think about any further.

The Higgs Boson is likely the first Higgs Boson, and there are two more.

@@edwardlulofs444, It is a new one. The Higgs Boson decays very quickly even if some scientists say that it doesn't spin. And it is not a behavior of a Boson.

Agree Sabine, Since the late 60's early 70's physics has gone way off track looking for crazy things like dark matter and string theory to name a couple. It seems the study of classic physics is to much a bore and won't get them the rock star name they seek. To many unfounded crazy offshoots going in all directions and many leaving out the basics in their predictions. I think a better understanding of what we have would lead to new findings. Thanks for the time and info shared with us.

Lovely. For whatever strange reason I got the feeling that maybe what we need is Occam's Razor to be far more substantial than a metaphor
