    Widely considered the greatest genius of all time, Albert Einstein revolutionized our understanding of the cosmos with his general theory of relativity and helped to lead us into the atomic age. Yet in the final decades of his life he was also ignored by most working scientists, his ideas opposed by even his closest friends. Bestselling author of E=mc², David Bodanis, discusses Einstein's Greatest Mistake, a brisk, accessible biography of Albert Einstein that reveals the genius and hubris of the titan of modern science.
    David Bodanis was born in Chicago, lived in France for a decade, and makes his home in London. He studied mathematics, physics and history at the University of Chicago, and for many years taught the "Intellectual Tool-Kit" course at Oxford University. He is fascinated by story-telling and the power of ideas.

    Albert's work is the best example of the power of deductive reasoning i can think of. He asked a simple question, proposed a simple answer, and followed it to it's logical conclusion, which turns out to be a very powerful expression of reality.

      It wasn't anything of the sort. Einstein was terribly wrong about a lot of things, a notorious affair loving cheater, and a plagiarist who got into several priority disputes. Even when many scientists tried to convince Einstein was wrong on several points about general relativity and quantum mechanics, he'd only admit he was wrong several years later.

    I think David Bodanis At 14:20 made a great mistake (and he repeats it again seconds later): during the 1919's expedition, Sir Eddington and others, proved that light (NOT time) bends because of gravity. That was the definitive confirmation that Einstein' theory was right, But NOT the confirmation that time slow down in presence of gravity.

      I agree completely! As I listened to David Bodanis explain the eclipse experiment I became very annoyed because it was obvious to me he was misleading the audience who must have been very confused because what he was saying could not have made any sense. I could not watch the rest of the presentation.

    I loved this lecture, very informative! Nice to hear someone focus on the human side of genius. We quickly grow used to changed circumstances, and we forget that human beings - often individuals working largely alone - can be the cause of seismic worldwide change … and that these individuals can have hard times, limitations, can put on blinkers (just like anyone else) that somehow limit in some small way their enormous contribution, leaving room for those to come to expand upon their innovation. A very nice take on Albert Einstein and his era.
    (It’s interesting, going through the comments, trying to guess the private agendas of people complaining about one aspect or another of this lecture: I suspect more than a few of them were drawn to the title hoping this was to be a “debunking” of Einstein’s findings, and a defense of their own pet quack theories? I guess I’m not sorry they’re disappointed, but I’m surprised they’d tune into a video from a channel devoted to legitimate science expecting to hear that magnets provide limitless energy or that Tesla was murdered for discovering this, etc. Maybe review the video you actually saw, rather than comparing it to the one you’d hoped to see?)

    I Have a problem with what he says at problem about 18 minutes, Light from a distant star is bent when it passes close to an object like the sun, but so does light from a point right behind the star so the star does not move in respect of its direct background which together with it, rather seems to move a bit while the sun "passes" as far as i can see.

      Well, we usually surmise what happens to photons by looking at electrons: we look at the particles we can and derive from them the rules by which we believe particles behave generally. Electrons are pretty easy to shake loose and - pew! pew! pew! - fire at a metal plate. While we _can_ increasingly, now, isolate and manipulate other particles, electrons _have_ generally been the go-to for experiments, and if someone’s talking about an older experiment in particle physics, it’s a good guess they’re talking about one conducted with electrons fired at a metal plate. Not knowing the time code of what comment you’re referring to, and not having myself noticed the lecturer say what you quoted, I’m just taking a guess at what he said, at its context, and at what he may’ve meant. But maybe he misspoke, perhaps? If you _do_ have a time code, I’d be curious to go back and watch the segment you’re referring to!

    Well, let's make something clear, both relativity and quantum theories have Einstein as instrumental in the foundation of both theories. Although Einstein was most famous for his theory of relativity, the 1921 Nobel Prize in Physics was officially awarded to Einstein for his work on quantum theory. Einstein made many important contributions to this field, the first of which was his 1905 paper on the photoelectric effect. From 1905 to 1923, he was one of the only scientists to take seriously the existence of light quanta, or photons. In 1916 Einstein came up with the theory of stimulated emission based on the quanta of light. This theory is what makes lasers possible today. Even today with the most recent discovery of the Higgs-Boson particle at CERN you see Einstein’s huge influence in Quantum Physics. The Higgs particle is called a Boson thanks to the work of Bose-Einstein statistics. In 1935 Einstein and his team discovered quantum entanglement which is the basis of Quantum computers. So, to say that Einstein was opposed to the weirdness of the small and was stuck with classical physics is wrong. Did he like his own findings? No. Did that stop Einstein from to doing research on it? No. Did Einstein miracle year stop in 1905? No. Nevertheless, Einstein was strongly opposed to the new version of quantum mechanics developed by Werner Heisenberg and Erwin Schroedinger and its uncertainty principle. Even today, there is still deep dissatisfaction among many physics about the probabilistic quality of today's quantum mechanics. It feels too much like an engineering solution rather than a physics solution in that we've given up on finding deeper principles of nature and left it to probability tables and chance.

    At the IAS, Einstein had a long relationship with Kurt Gödel. I've read _Turing's Cathedral: The Origins of the Digital Universe_ (2012) by George Dyson, and some of Freeman's own recounts of his time at the IAS, so I'm not longer sure from which source I picked this up, but even during Einstein's intellectual isolation from most of the physics community, he had a constant stream of important people in the arena of global arms control making a pilgrimage to Princeton to confer with Einstein, sometimes on an almost daily basis. I got the feeling from one of these Dyson accounts that half of Einstein's time was devoted to quiet diplomacy, where he was anything but isolated. _Turing's Cathedral_ is a good read for those who are interested in this sort of thing. An excellent wine pairing is to read it alongside _Big Science: Ernest Lawrence and the Invention That Launched the Military-Industrial Complex_ (2015).

    Apple Force ( formerly known gravitational force ) is invisible energy that takes any shapes if it should and through which every single object is being compacted to their common center. If there was curved of Apple Force in the center of the solar system, there would have been compacted forces among the lines of the series of the centrifugal forces evident, resulting intensifying of the planetary Apple Forces and for which mass would have been compacted and be exploded. Water would have act like rock without being cold. Furthermore, any planet would not be rotated either for counter centrifugal force resistance with planetary densifying Apple Forces.

      He is referring to entanglement, or the property exhibited by two quantum particles that remain entangled through their properties even at long distances. Einstein called it “spooky action at a distance.” This entanglement causes a conundrum with relativity because nothing can travel faster than light, however entangled quantum particles communicate instantaneously.

      His theory predicted space should be expanding but current experimental evidence said it wasn't so he adjusted his theory to match the data. After the discovery that it WAS expanding he overcompensated and became TOO confident in his physical intuition. I'm sure the odds didn't seem too bad at the time since he had already almost singlehandedly created ONE completely new theory. Anything less probably felt like busywork to him.

For decades since Copenhagen physicist were ridiculed for trying to understand the fundamental concepts.

Relativity is the ultimate formulation of classical physics; everyone who came after Einstein had to deal with quantum physics instead.

The more a particle interacts with the higgs field, the "harder" that particle is to accelerate, which is the definition of Mass.

    Quantum Entangled Twisted Tubules:
    When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons.
    Alpha decay occurs when the two protons and two neutrons (which are bound together by entangled tubes), become un-entangled from the rest of the nucleons.
    Beta decay occurs when the tube of a down quark/gluon in a neutron becomes overtwisted and breaks producing a twisted torus (neutrino) and an up quark, and the ejected electron.
    Gamma photons are produced when a tube unwinds producing electromagnetic waves.

    Well, I think this is a clever way to misdirect the gravity/mass theorized relationship with a 'curvature of time' instead of the 'curvature of the fabric of space/time.' It completely ignores that this theorem would negate E=MC² and since C² is variable and not a constant. Trying to reify 'Time' as an object is just another miraculous creation like the similarly miraculous 'Fabric of Space' out of Zero. Act One: In-the-beginning there was nothing, no material sources and only pointless space; zero (0). Act Two: Then the space was provided with points which caused a fabric of space with the time between those points. Act Three: Then the material sources, the mass of the universe removed before, are replaced and curve the pointed space/time; both in time and physically. All a creation out of Zero ... Now, the God of Science is Einstein, since deity is a unicorn ... and circular logic is now the primary tool of cosmology ...

A better theory that unifies gravity and includes predictable forces or particles may be developed that could show what is beyond the Higgs or that the Higgs is not important at all. Electrons may even be shown from another angle to show why they behave the way they do and have more of predictable nature that doesn’t place the current emphasis on quantum superposition I.e. Schrodingers cat might be pre determined based on another factor we currently aren’t measuring or are able to understand how to measure. Given Einstein has been vindicated numerous times, even despite his own occasional self doubt, probability would say he will be vindicated again one day.

    I try to combine the cosmological constant and the schrodinger solution on the planck scale.
    I used planck units.
    At the end I went back to SI units to compare with the measured vacuum energy density (0.63 10^-9 J/m^3.)
    Combine:
    1) Einstein, cosmological constant
    2) Schrödinger solution
    3) Planck units
    Result:
    - vacuum catastrophe solved?
    1)Einstein, cosmological constant
    Λ = (8π 𝐺 ƐΛ)/(𝑐^4)
    Planck units:
    G=1
    c=1
    Λ (6.1871424 10^34)^-2 = (8π ƐΛ [planckEnergy/planckVolume]
    1.1056 10^-52 (6.1871424 10^34)^-2 = 8π ƐΛ
    0.001149 10^-120 = ƐΛ
    0.1149 10^-122/ ƐΛ = 1
    2)Schrödinger solution, n=1
    (ℎbar^2 𝑛^2 𝜋^2) / (2𝑚𝐿^2) = E
    Planck units
    hbar=1
    n=1
    m= mplanck =1
    L= Lplanck=1
    0.5 𝜋^2= E
    1= E/0.5 𝜋^2
    3)Einstein, Cosmological Constant = Schrödinger solution
    0.1149 10^-122/ ƐΛ = 1 = E/0.5 𝜋^2
    0.1149 10^-122 0.5 𝜋^2= ƐΛ Eplanck
    Eplanck =1
    0.1149 10^-122 0.5 𝜋^2= ƐΛ
    0.567 10^-122 = ƐΛ [planckEnergy/planckVolume]
    0.567 10^-122 1.9561 10^9 /(1.61625502 10^-35)^3= ƐΛ [J/m^3]
    ƐΛ = 2.627 10^-9 [J/m^3]
    Measured: 0.63 10^-9 [J/m^3]
    I am looking forward to your response.

    This was a mixed bag. I think pointing out Einstein's isolation is good and interesting. However, the title is misleading at best, there's mistakes in the science, and I've seen and heard much better explanations of a lot of the ideas. A few did help me understand things better for example I never heard of the way he started thinking about relativity's equation as just G=T. The props are just a stylistic choice, to me. It makes some of the audience more interested at the chance of making them more focused on chocolates than the talk.

    The event between Bohr and Einstein is a routine story told in many books, but this lecture reverses it's character. It is always Bohr who challenges Einstein several times in a conversation, and Einstein's off-the-cuff thoughts are demolished by Bohr without hesitation. Bohr leaves Einstein with the challenge, but Einstein later does think up something not instantly refutable. Bohr took some hours of thinking to counter, but only because uncertainty combining with Relativity was a surprising thought at the time. Bohr was mildly impressed that Einstein could think of anything that would take so long as hours for Bohr to resolve.
    The picture with Einstein smiling next to the sombre Bohr does not indicate something about this conversation. Einstein smiled easily, and smiling for people who were always taking pictures was practically an involuntary reflex. Bohr always looks severe in pictures, like he did in that picture.
    In short, the angle this lecturer imposed on the story is deceptive. I wonder if he garbaged up the whole book like this.

    If one is accelerating, one will feel the effects of force, and one will detect the Doppler effect when observing any non-accelerating light sources.

      It has never been measured, apparently. See youtube 'veritasium'. That is: "in ONE direction'. Only ever in two directions. There and back. Common sense says it is the same both ways. But you know science - don't trust common sense, check it, prove it, for often we've found the 'common sense' or 'intuitive' answer is wrong. Hence they consider it a valid point: it has never been measured (in one direction).

    Sadly the speaker did not understood that General Theory of relativity is not about 'squeezing' time, it is about non-existence of time as a real thing. It explains how time is a relation between point of view and change.

    • @MrDNMock
      @MrDNMock 7 років тому +2

      what? Time most certainly exists in Relativity. All relativity does is explain exactly what time is, which is a dimension of space, hence why it is referred to as Space-Time now. Time is the 4th dimension of space and can be manipulated just like the other 3 dimensions, length, width, and depth.

    • @ghromm
      @ghromm 7 років тому +1

      ROFL. The ENTIRE point of GR by Einstein is that time is just a relation of change between things, not a dimension in any sense. If time is a dimension, there is infinite number of dimensions of time, because time is different from each and every point of space. And you, Sir, are welcome to embrace this and thus reduce your cognitive dissonance.

    • @MrDNMock
      @MrDNMock 7 років тому +3

      Just to add, what do you think length, width, and depth are if not a relation of view? GR proved that as you warp space, so too do you warp time. a straight line becomes a curved line and has to travel a longer distance to get from A to B. Time becomes warped in the exact same way, and slows down in the exact same proportion (this is why you cannot move faster than the speed of light, your time slows down more and more until it completely stops, just like on the event horizon of a black hole). This proves that time isn't a separate entity from space, but just another dimension within space, ergo Space-time.
      Please, PLEASE, learn the fundamentals at least before you start saying non-sense, especially about someone who is intelligent enough to be doing a lecture at the Royal Institute.

Nowhere does it speak of “a relation of change between things” or “infinite number of dimensions of time”. (_Gravity_, or gravitational forces, is what does not really exist according to GR, instead.) See e.g. . As for “cognitive dissonance”, you should read .

I think we cant see those feilds or rays what ever its called, its because we dont have the right type of prism.

      ArcStealth, I hope he did not write E² = m c², too. Because the correct equation is E = m c², but only if either E is rest energy (E := E_0) and m is (rest) mass (m := m_0), or E is total energy and m is “relativistic mass” (m = m_rel; from the energy-momentum relation E² = {m_0}²c⁴ + p²c², E = γ m_0 c²). Therefore, regarding your statement about mass, it is correct if one means (Lorentz-)invariant/rest mass m_0 by that, as is common in modern physics; it is not correct if one means the deprecated “relativistic mass” m_rel = γ m_0 as the Lorentz factor γ = 1/✓(1 - v²/c²) is a function of the relative velocity v, thus _not_ Lorentz-invariant.

    Thats the matter...THE THREE PILLARS OF BEING
    The present, the common and the mutual complement.
    Everything is now at the same time and it is a lot at the same time, although the possibly previous nothing from which everything should come, but is so poor and without energy. So much power can not have made that boundless being necessary to appear. But it is the entity anyway just momentary, a fictional Augernblick, but in a moment that lasts because there is no opposition to him which can put him in the place.
    Purely fictional to the effect factor for also fictional, that is that flesh of the present which ultimately consists of nothing more than from the recognition of others.
    The vain dream each other to effectiveness.
    This trick creates the world that remains out of nothing, in the groundless immaterial and stays there effortlessly and therefore tirelessly.
    The now, the time, the space, the energy, all these units of measurement are not concrete.
    There are the present, the moveable, the united, the structure-builders that complement each other in their respective contexts.
    This makes nature complex enough and it must be whimsical anyway, after all, it has transcended nothingness infinitely, it is not just a one that can never arise through any amount of zeros, it is suggestive and that makes the difference in comparison with any building block models.
    The now knows no stretch, the now is whole, the now does not draw into the borderlessness, on the contrary, it is completely dense and close and purely fictional.
    But this term is not reality, it's just a conceptual tool. The true substance is called wholeness. But this is both comprehensive and concentrated at the same time and is therefore irritating, because any other conceptuality fails.
    The term wholeness perfectly corresponds to our soul. Nothing is closer and more certain, but as soon as we stop thinking about anything, it runs from our fingers.

      No, it didn't. But then again, did you really need to watch a 50 minute lecture to tell you a single fact you already knew?

    Einstein was right to not accept the Copenhagen interpretation of quantum theory. It must have taken great courage to go against the currently accepted wisdom but he was right to do so. Once the correct revisions are made to current theories of physics it will be clear that the Special theory and the General theory of relativity are the only one's left standing. Well done Einstein.

      If what you say were true, you could not have written it, because your computer, which is based on QM, would not have worked. IOW, by making the argument this way you have already refuted it.

      Sorry mate but you are wrong. That personal computer you are using is not working because of QM but because of the electromagnetic force. It is ok if you don't understand how computers work, most people don't but please do not write nonsense.

      Pot calling the kettle black. Read up on QED some time, right after you studied computer science (like me).

    I skipped this lecture because I didn’t like the Pharmaceutical Sponsor. Gotta draw the line.
