I met Paul Dirac, near the end of his life, when he was professor emeritus at Florida State University. I was a typist for the Physics Dept. in 1983, and I typed what may have been his last paper (or one of his last), an overview of the field of physics. I kept a Xerox copy for many years, and finally donated it to the organization that preserves his legacy. I remember him as being very cordial to me.

[@johnshuster9475]

At the start, this account mentions, "Dirac believed that fundamental laws of Nature are found be expressed by 'pretty' equations", but this was not emphasized at the end. I was surprised by this, since Dirac held this belief more and more by the end of his life. To him, Truth had to beautiful, as his equation. His agnosticism became more the belief of a believer! We should remember his belief -- for he was probably right! :)

My favourite Dirac story comes courtesy of my old maths supervisor at Cambridge, who knew him personally. He recounted how he and his wife had entertained Dirac to dinner. As usual, Dirac said nothing the entire evening, but just sat there quietly observing the wife knitting, which he had never seen before but which clearly fascinated him. As he left at the end of the evening, he made a single remark: that there were just two distinct ways of creating a stitch. He was right, of course; but imagine having the kind of mind which could analyse knitting in the abstract and reach that conclusion!

@@ThatsWhenItkickedin There are other types of stitches but the wife was only using the basic two (a clockwise stitch & an anti-clockwise stitch that is reversed if you look from the other side of the knitted fabric). You can double (or multiple) wrap a stitch before pulling it through or add two stitches on one loop. There are hundreds of stitches but I know very little about knitting.

[@MrPLC999]

I'm gonna have to nominate Einstein's E=mc^2 as the most elegant and profound equation in all of math and physics. It states that mass can be converted to energy -- and the reverse -- energy can be converted to mass. This has enormous implications for the formation of the physical universe from the energy supplied by the Big Bang. Going in the opposite direction, we derive incredible amounts of energy from small amounts of mass that undergo nuclear reactions.

I'm an astrophysicist and long-time admirer of Dirac. This brief bio of his life was exceptionally well-produced; bravo, and thanks for giving one of my scientific heroes the attention he is due. As a personal story, I once was invited to a scientific meeting at Cambridge, and they housed us on campus, staying in what had been faculty chambers. The room I was given I was told was once Dirac's quarters. They didn't know of my long-time admiration of Dirac, so it wasn't planned; what an unexpected thrill! -Tom

Given that he was apparently a bit of a recluse, it is interesting to note that he spent 6 months in Calcutta (now Kolkata) in 1928 to discuss various aspects of quantum mechanics with Satyendra Nath Bose, after whom bosons are named. The name was given by Dirac himself, who also coined the name fermion for its opposite counterpart - particles that followed Fermi-Dirac statistics. His modesty in not naming them after himself was apparent.

[@FredPlanatia]

he was the epitome of modesty, but physicists generally do not name things after themselves. Equations or ideas come to carry their name because other physicists speak of them that way. "Dirac's equation", later "the Dirac Equation". An interesting exception is E=mc^2. It did not come to be known as 'Einstein's equation', perhaps it was just so short its easy enough to say 'E equals m c squared'.

1. Bosons are INCORRECTLY named after Bose. Bose, unbeknownst to himself, created what are now know as Bose-Einstein Statistics (which really should just be called Bose Statistics). However, the Boson was 100% Einstein NOT Bose. They should be named after Einstein (but for interesting historical reasons aren't, the same way Dirac should have gotten credit for creating quantum field theory, not Feynman). To quote Professor Douglas Stone, head of Applied Physics at Yale, "Bosons weren't actually predicted by Bose, Bose, unwittingly created a new statistical framework to derive the planck's equation but he was unaware that what he was doing was novel. Even after his paper was published, Schrodinger, who read it, was unaware of any novel ideas in Bose's paper. It was Einstein who predicted Bose-Einstein Condensates, not Bose - who had nothing to do with it's prediction - and Boson's should be called Einsteinions but that may have been too much of a mouthful to pronounce." Reference: Einstein and the Quantum: The Quest of the Valiant Swabian (by Douglas Stone). Einstein predicted the Boson NOT Bose. And i suspect Dirac probably didn't derive much knowledge from speaking to Bose because Einstein, who sponsored Bose, had Bose's paper published when NOBODY ELSE WOULD (and got it translated into English even though German was the lingua franca of physics), wrote to other physicists pointing out how and why Bose's paper was original (even showing Schrodinger how Bose' new statistics was 1/3 not 1/2, the defining quality which separates BE Statistics from FD Statistics), got Bose a JOB a prestigious European university, and gave Bose an assignment in the new field of quantum mechanics (something to do with Heisenberg's Uncertainty Principle and Matrix Mechanics, which was 100% Max Born, not Heisenberg, even though the latter typically gets credited with it). Bose, by his own admission, could not complete the assignment and within a few years of publishing his brilliant paper, was out of physics. By his own admission "I was like a comet." 2. Bose would have remained unknown for the rest of his life without Einstein. He had tried for months to get his paper published, but nobody of any repute would publish it. 3. Dirac coined the term Boson, but even HE didn't quite grasp the novelty of Bose's paper UNTIL Einstein wrote a primer on it explaining the novelty of what Bose had done. These are the reasons why we just call it BE Statistics and BE Condensates even though the former was 100% Bose and the latter (the Boson) was 100% Einstein. The more you know.... 😉

[@feynmanschwingere_mc2270]

@@FredPlanatia I mean LOTS of equations are INCORRECTLY named after the wrong guy. We've found tons of equations for which the attribution PREDATES the person who was credited for it. Often MULTIPLE geniuses will think of an equation at roughly the same time independent of each other, but for strange historical reasons, one person will get credited for the discovery while the other person is ignored. I mean most people erroneously credit newton with the invention of calculus when Leibniz published it first and gave us the notation we STILL USE TODAY: dy/dx History is a funny thing. The Boson is named after Bose, but it should have been named after Einstein. The Raleigh Jeans Equation is another example. Sooo many equations are like this.

[@feynmanschwingere_mc2270]

P.S. Dirac was VERY modest. And it should be noted that his most famous equation wouldn't have been possible without help from Oppenheimer and Hermann Weyl. But that's a story for another day. There is no such thing as a "lone genius." Not Archimedes, Not Newton, NOBODY is a lone genius. They all interacted with out geniuses and thinkers, they all corresponded with mentors and teachers and wrote letters to vet their ideas. We still have letters from Huyygens to Newton!

Dirac achieved something very rare in physics - he theoretically predicted a new phenomenon (anti-matter) through pure math. Not only that, but much of the math of Dirac was derived earlier by the mathematicians Eli Cartan and Wilhelm Killing. They studied the symmetries of space, and found that rotations in 3d space are equivalent to rotations in a special 2d space. This allowed Dirac to take the "square root" of the Klein-Gordon equation, which produced a linear and relativistic quantum wave equation (the Dirac equation). Dirac found that his equation has two solutions, one for electrons and another for anti-electrons (positrons).

A graduate student was "asked" to please see if he could help shovel out Professor Dirac's automobile. When he arrived, he found the tires (tyres) frozen to the driveway, and the driveway coated with treacherous ice. It seems that Professor Dirac, whose experience was with Britain and Florida's milder winters had "helpfully" poured hot water from the "kettle" (i.e., "teapot" in 'Merican) around the tires where it had frozen solid.

Don't' forget Julian Schwinger and Tomonaga! Every bit as smart as those aforementioned two. I agree with you though. Feynman and Dirac (and Einstein before them) had the most intuitive understanding of the quantum world. Remember, quantum entanglement was staring Schrodinger, Heisenberg, Dirac, Born, Bohr, etc, all in the face. It took Einstein in 1932 to point out that it was ENTANGLEMENT that was the truly bizarre property of quantum mechanics (and Einstein's EPR paper was basically ignored until John Bell's inequalities - but now forms the foundation of quantum information theory).

Thank you, Cindy, for lifting up the life of Paul Dirac! I met him quite briefly near the end of his life, and his manner was very sweet and modest. He said that he regarded his own contribution to theoretical physics to reflect his luck to live in the "golden age of quantum mechanics", where new discoveries were like "low-hanging fruit". His theory, which was the first to synthesize quantum mechanics with special relativity, predicted the existence of an anti-particle simply as a particle propagating "backwards in time", as Richard Feynman characterized it. However, there was the confounding presence of infinite energy or mass in the theory, which took two more decades of theoretical physics development to explain away, resulting in what we now refer to as quantum electrodynamics, considered a triumph of theoretical physics. Dirac saw within his lifetime the maturation of his theory into the integration of the weak nuclear interaction with his own quantum electrodynamics to form a successful unified theory. He also witnessed its further development with gauge field theory, SU3, and the Standard Model. All before he passed away. My fond notion is that he could permit himself to let go of the label of "failure" by the end of his life. He certainly impressed me as a happy person. ~~~~Arthur Ogawa

1) Calculus Foundations: Contradictory: Newtonian Fluxional Calculus dx/dt = lim(Δx/Δt) as Δt->0 This expresses the derivative using the limiting ratio of finite differences Δx/Δt as Δt shrinks towards 0. However, the limit concept contains logical contradictions when extended to the infinitesimal scale. Non-Contradictory: Leibnizian Infinitesimal Calculus dx = ɛ, where ɛ is an infinitesimal dx/dt = ɛ/dt Leibniz treated the differentials dx, dt as infinite "inassignable" infinitesimal increments ɛ, rather than limits of finite ratios - thus avoiding the paradoxes of vanishing quantities. 2) Continuum Hypothesis: Contradictory: Classic Set Theory Cardinality(Reals) = 2^(Cardinality(Naturals)) The continuum hypothesis assumes the uncountable continuum emerges from iterating the power set of naturals. But it is independent of ZFC axioms, and leads to paradoxes like Banach-Tarski. Non-Contradictory: Non-standard Analysis Cardinality(*R) = Cardinality(R) + 1 *R contains infinitesimal and infinite elements The hyperreal number line *R built from infinitesimals has a higher cardinality than R, resolving CH without paradoxes. The continuum derives from ordered monic ("monadic") elements. 3) Quantum Measurement: Contradictory: Von Neumann-Dirac collapse postulate |Ψ>system+apparatus = Σj cj|ψj>sys|ϕj>app -> |ψk>sys|ϕk>app The measurement axiom updating the wavefunction via "collapse" is wholly ad-hoc and self-contradictory within the theory's unitary evolution. Non-Contradictory: Relational/Monadic QM |Ψ>rel = Σj |ψj>monadic perspective The quantum state is a monadological probability weighing over relative states from each monadic perspectival origin. No extrinsic "collapse" is required. 4) Gravitation: Contradictory: General Relativity Gμν = 8πTμν Rμν - (1/2)gμνR = 8πTμν Einstein's field equations model gravity as curvature in a 4D pseudo-Riemannian manifold, but produce spacetime singularities where geometry breaks down. Non-Contradictory: Monadological Quantum Gravity Γab = monic gravitational charge relations ds2 = Σx,y Γab(x,y) dxdydyadx Gravity emerges from quantized charge relations among monad perspectives x, y in a pre-geometric poly-symmetric metric Γ, sans singularities. In each case, the non-contradictory formulation avoids paradoxes by: 1) Replacing limits with infinitesimals/monics 2) Treating the continuum as derived from discrete elements 3) Grounding physical phenomena in pluralistic relational perspectives 4) Eliminating singularities from over-idealized geometric approximations By restructuring equations to reflect quantized, pluralistic, relational ontologies rather than unrealistic continuity idealizations, the non-contradictory frameworks transcend the self-undermining paradoxes plaguing classical theories. At every layer, from the arithmetic of infinites to continuum modeling to quantum dynamics and gravitation, realigning descriptive mathematics with metaphysical non-contradiction principles drawn from monadic perspectivalism points a way forward towards paradox-free model-building across physics and mathematics. The classical formulations were invaluable stepping stones. But now we can strike out along coherent new frameworks faithful to the logically-primordial mulitiplicites and relational pluralisms undergirding Reality's true trans-geometric structure and dynamics.

Dirac's view of religion is just like mine, i couldn't believe someone would have my exact view on religion . He was also a good human being, unlike some of the famous theoretical physicists at that time. I also love seeing the Dirac equation, as an aspiring theoretical physicist.

I had initially planned to retire at 62, work part-time, and save money, but the impact of high prices on various goods and services has significantly disrupted my retirement plan. I'm worried about whether those who experienced the 2008 financial crisis had it easier than I currently am. The volatility of the stock market is a concern as my income has decreased, and I fear that I won't be able to contribute as much as before, potentially jeopardizing my retirement savings.

[@GeraldE.Meehan]

The increasing prices have impacted my plan to retire at 62, work part-time, and save for the future. I'm concerned about whether those who navigated the 2008 financial crisis had an easier time than I am currently experiencing. The combination of stock market volatility and a decrease in income is causing anxiety about whether I'll have sufficient funds for retirement.

This is precisely why I like having a portfolio coach guide my day-to-day market decisions: with their extensive knowledge of going long and short at the same time, using risk for its asymmetrical upside and laying it off as a hedge against the inevitable downward turns, their skillset makes it nearly impossible for them to underperform. I've been utilizing a portfolio coach for more than two years, and I've made over $800,000.

Paul Dirac was a GENIUS and one of the 5 greatest physicists ever. They claimed he was autistic, but that's idle speculation, never confirmed. The man essentially created quantum field theory without even being aware he was doing it (as Feynman later said). He was INCREDIBLE. Dirac Metals are really interesting too; I'm hoping you guys will cover that in a later video. However, this video is really bad click bait and I didn't really learn what makes an equation "beautiful." Calling ANY equation "the world's most beautiful equation" without first establishing the criteria of what makes ANY equation "beautiful" to begin with, is intellectually dishonest and insults the intelligence of your audience. This is a click-bait title, but I get it, you need the clicks and eyeballs. Euler's identity is traditionally considered the most "beautiful equation in the world" because it's ostensibly simple but encodes a lot of complexity within it (and it has wide applications). You made a whole video and I STILL don't know why it's more "beautiful" than Newton's law of gravitation or the Einstein Field Equations or Maxwell's EM equations. CLICK BAIT. Love your channel, but this video is silly. I still don't know what makes the Dirac equation "the most beautiful" lol. Why not do a wide historical sampling of ALL the equations in the history of mathematics that are considered by ACTUAL mathematicians to be the "the most beautiful equations," and then showing how Dirac's equation is in accord with the intellectual spirit of those other "beautiful equations." CLICK BAIT.

Why didn't Maxwell himself discover special relativity or, at least, the Lorentz transformation?

[@arctic_haze]

@kyintegralson9656 A good question. Maybe he was afraid his equations were not precise because they did not transform well? Even Lorenz did not believe in the physical reality of the transformation he proposed. Einstein was the first one who fully accepted what was implied by Maxwell's equations.

Excellent video and thank goodness for KZbin and videos such as these. A couple of observations and an approximate timestamp: 6:30 may I suggest changing 'elections;' to 'electrons'? 7:40 I do ponder and wonder if our human bipedal nature introduces a subtle bias? Why electron and proton? If these things have a range of possibilities can we establish a range of probabilities of those occurring? The "matter" and/or "anti-matter" views are almost a good example of what I mean. Why not range of all possible states, probability of each of those states and likelihood of encountering those states?
