    Thank you. As an Australian, I am very proud of Sir Mark Oliphant. It also might explain why Heisenberg never got the bomb. because they never had the breakthrough that frisch and peierls had made. If not for their breakthrough, and the efforts Sir Mark, then I hypothesise that their Uranium project would have gone the same way as the german project from by Heisenberg; and the out of war in the Pacific would have been very different.

      I am glad that you liked the necessary mention of Oliphant, I also found it unfair when only a few names get all the credit. Science, like many other human endeavors, is build by many contributors and usually only a few get popular. It is my intention to bring some of the less-known but still crucial names to general audiences.

      @@jkzero Conservation of Spatial Curvature (both Matter and Energy described as "Quanta" of Spatial Curvature)
      Is there an alternative interpretation of "Asymptotic Freedom"? What if Quarks are actually made up of twisted tubes which become physically entangled with two other twisted tubes to produce a proton? Instead of the Strong Force being mediated by the exchange of gluons, it would be mediated by the physical entanglement of these twisted tubes. When only two twisted tubules are entangled, a meson is produced which is unstable and rapidly unwinds (decays) into something else. A proton would be analogous to three twisted rubber bands becoming entangled and the "Quarks" would be the places where the tubes are tangled together. The behavior would be the same as rubber balls (representing the Quarks) connected with twisted rubber bands being separated from each other or placed closer together producing the exact same phenomenon as "Asymptotic Freedom" in protons and neutrons. The force would become greater as the balls are separated, but the force would become less if the balls were placed closer together.
      -----------------------------------------------------------------------------------------------------------------------------------------
      String Theory was not a waste of time, because Geometry is the key to Math and Physics. However, can we describe Standard Model interactions using only one extra spatial dimension?
      What if we describe subatomic particles as spatial curvature, instead of trying to describe General Relativity as being mediated by particles? Fixing the Standard Model with more particles is like trying to mend a torn fishing net with small rubber balls, instead of a piece of twisted twine.
      Quantum Entangled Twisted Tubules:
      “We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct.” Neils Bohr
      (lecture on a theory of elementary particles given by Wolfgang Pauli in New York, c. 1957-8, in Scientific American vol. 199, no. 3, 1958)
      The following is meant to be a generalized framework for an extension of Kaluza-Klein Theory. Does it agree with the “Twistor Theory” of Roger Penrose, and the work of Eric Weinstein on “Geometric Unity”? During the early history of mankind, the twisting of fibers was used to produce thread, and this thread was used to produce fabrics. The twist of the thread is locked up within these fabrics. Is matter made up of twisted 3D-4D structures which store spatial curvature that we describe as “particles"? Are the twist cycles the "quanta" of Quantum Mechanics?
      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. ( E=hf, More spatial curvature as the frequency increases = more Energy ). 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 a part of the quarks. Quarks cannot exist without gluons, and vice-versa. 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 Charge" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" are logically based on this concept. The Dirac “belt trick” also reveals the concept of twist in the ½ spin of subatomic particles. If each twist cycle is proportional to h, we have identified the source of Quantum Mechanics as a consequence twist cycle geometry.
      Modern physicists say the Strong Force is mediated by a constant exchange of Mesons. The diagrams produced by some modern physicists actually represent the Strong Force like a spring connecting the two quarks. Asymptotic Freedom acts like real springs. Their drawing is actually more correct than their theory and matches perfectly to what I am saying in this model. You cannot separate the Gluons from the Quarks because they are a part of the same thing. The Quarks are the places where the Gluons are entangled with each other.
      Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. The twist in the torus can either be Right-Hand or Left-Hand. Some twisted donuts can be larger than others, which can produce three different types of neutrinos. If a twisted tube winds up on one end and unwinds on the other end as it moves through space, this would help explain the “spin” of normal particles, and perhaps also the “Higgs Field”. However, if the end of the twisted tube joins to the other end of the twisted tube forming a twisted torus (neutrino), would this help explain “Parity Symmetry” violation in Beta Decay? Could the conversion of twist cycles to writhe cycles through the process of supercoiling help explain “neutrino oscillations”? Spatial curvature (mass) would be conserved, but the structure could change.
      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?
      Does an electron travel through space like a threaded nut traveling down a threaded rod, with each twist cycle proportional to Planck’s Constant? Does it wind up on one end, while unwinding on the other end? Is this related to the Higgs field? Does this help explain the strange ½ spin of many subatomic particles? Does the 720 degree rotation of a 1/2 spin particle require at least one extra dimension?
      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. The production of the torus may help explain the “Symmetry Violation” in Beta Decay, because one end of the broken tube section is connected to the other end of the tube produced, like a snake eating its tail. The phenomenon of Supercoiling involving twist and writhe cycles may reveal how overtwisted quarks can produce these new particles. The conversion of twists into writhes, and vice-versa, is an interesting process, which is also found in DNA molecules.
      Gamma photons are produced when a tube unwinds producing electromagnetic waves.
      The “Electric Charge” of electrons or positrons would be the result of one twist cycle being displayed at the 3D-4D surface interface of the particle. The physical entanglement of twisted tubes in quarks within protons and neutrons and mesons displays an overall external surface charge of an integer number. Because the neutrinos do not have open tube ends, (They are a twisted torus.) they have no overall electric charge.
      >>>>>>>>>>>>>>>>>>>>>>
      Within this model a black hole could represent a quantum of gravity, because it is one cycle of spatial gravitational curvature. Therefore, instead of a graviton being a subatomic particle it could be considered to be a black hole. The overall gravitational attraction would be caused by a very tiny curvature imbalance within atoms. We know there is an unequal distribution of electrical charge within each atom because the positive charge is concentrated within the nucleus, even though the overall electrical charge of the atom is balanced by equal positive and negative charge.
      >>>>>>>>>>>>>>>>>>>>>>
      In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137.
      1= Hypertubule diameter at 4D interface
      137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted.
      The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.)

      How many neutrinos are left over from the Big Bang? They have a small mass, but they could be very large in number. Could this help explain Dark Matter?

      I started out imagining a subatomic Einstein-Rosen Bridge whose internal surface is twisted with either a Right-Hand twist, or a Left-Hand twist producing a twisted 3D/4D membrane. The model grew out of that simple idea.

    Hey Jorge, love your videos! Came here from the 3B1B shout and got stuck binging all your videos. I'm a physicist as well, so I might be biased and a bad test audience, but is there any chance we'll get the "solving the neutron diffusion equation" video? Doing so with different boundary conditions (like periodic ones for perfect neutron reflectors) could also be a fun lead in to more minutiae of bomb design.
    I also found your talk on shockwaves very interesting! I've always wondered how that transition from fast shockwave to sonic went. Another transition of shockwaves I always wondered about is the transition from 1/R² to 1/R scaling of shockfront energy density / overpressure. For the really big guns it is said that once the atmosphere is thin compared to the radius of the shockwave 1/R scaling becomes more accurate than the 1/R² of a sphere. I wonder whether the system of equations you present in that talk is solvable if you add variable ambient densities and speeds of sound with altitude.
    Hope you continue making such excellent physics videos and regards from the university of hamburg/DESY!

    Thank you, Dr. Jorge S. Diaz, this was once again a very interesting and educational video. I have engaged in discussions with several educated individuals, and I have consistently maintained the position that the theory of relativity was largely irrelevant to the construction of the first nuclear weapons. Even a friend of mine who holds a doctoral degree in physics disagreed with me, asserting that the theory of relativity was essential for the development of the initial atomic bombs. He staunchly refused to concur with my viewpoint that the theory of relativity had no direct influence on the discovery of nuclear fission and was primarily necessary for calculating the energy release. It is worth noting that knowledge of the exact yield is not imperative for the development of such weapons. Furthermore, discrepancies arise due to the fact that the material to be split is not perfectly homogeneous, and the neutrons ejected do not all fly out of the atomic nuclei at exactly the same angle. All of this is much less about the theory of relativity than about calculating the probabilities of the cross section of the material constellation used.

    *All* energy is mass in GR-even winding a watch increases its mass. Nuclear decomposition is just the first place where you have energy scales significant enough for the change in mass to be noticeable. So I think it is misleading to say that E=mc² is where the energy of nuclear weapons comes from, because that's arguably true of all explosives. It's just that baryon interactions start getting involved instead of purely fermions and photons, and there's a lot more binding energy involved there.

      It was hardly "plug and play." Every physicist working on atomic physics in the U.S. understood the idea of bringing two subcritical masses together to make a critical mass. You can find the MAUD Report online. I'd suggest reading it. At best it is a compilation of atomic physics knowledge at that time and hardly a blueprint for building a bomb. The gun design was so obvious it was hardly novel. In fact, the gun design described in the MAUD Report is totally different than the final design used for Little Boy. MAUD showed two guns firing subcritical masses at each other, Little Boy used a single mass fired at a stationary target mass. Everything in the MAUD Report was already known by U.S. physicists. The MAUD Report summarized the state-of-the-art at that time in a single report. It provided independent verification that making a bomb was possible and helped convince the U.S. government to prioritize atomic bomb research.

Shortly after that, Phillip Morrison (one of Oppenheimer's graduate students) remembered walking into Oppenheimer’s office and seeing on the blackboard, “a drawing - a very bad drawing an execrable drawing - of a bomb.” The MAUD Report was not the magic key to the atomic bomb that some people want to make it into.

    Fascinating videos on the bomb by Dr. Diaz. Germany was incapable of producing the bomb because they didn’t have the resources to undertake the massive engineering project that producing the bomb became.

      I am glad you found the content of interest. I am curious to know what brings viewers to the channel, were you searching for something in particular? You are right about the failure of the German program, they didn't have the resources but there were also technical mistakes, from wrong calculations to wrong measurements, I have a video about this on my list to do in the near future. Thanks for watching and welcome to the channel.

      I included this hoping for someone to spot the "Easter egg." I also find it fascinating that artificial fusion was achieved before artificial fission. Oliphant introduced several innovations in the new world of particle accelerators and used them to bombard light elements with one another, this is how he and the team at Cavendish Lab achieved fusion.

    Con todo respeto: Puede que la famosa ecuación de A. Einstein no fuera relevante en la parte práctica de la construcción de la bomba. Pero me resulta imposible creer que sin su concepto su bisabuelo hubiera llegado a tales conclusiones. Como tampoco S. Hawking reconoció nunca la aportación del espacio tiempo para las suyas. ¿Se trata de envidia profesional?.

      gracias Rubén por el comentario; comprendo y acepto tu esceptisismo, encantado de respetuosamente discrepar. Sin embargo, he leído los documentos científicos y es posible notar que nadie necesitaba conocer el origen de la energía producida en la reacción; es bueno saber de dónde proviene la energía pero no es necesario. Una vez determinado el valor de esta energía liberada, el resto se transformó en un problema de física aplicada e ingeniería más que física fundamental. Encantado cambiaré mi opinión pero para eso necesitaría encontrar evidencia concreta más que opiniones, y en mis años investigado este tema sólo encuentro evidencia de lo contrario: para el desarrollo formal de la bomba nuclear la famosa fórmula de la equivalencia entre masa y energía es irrelevante.
      Desconozco a qué refieres con el comentario sobre Hawking, ¿podrías elaborarlo? Y sobre la posible "envidia profesional", no, tenerle envidia a Einstein sería algo demasiado infantil. Es como que un deportista le tenga envidia a los atletas de elite. Se les puede admirar o ignorar, pero ¿tenerles envidia? Eso reflejaría un problema más grave. Yo crecí con un póster de Einstein en mi habitación y hasta tuve un perro con su nombre :)

      ​@@jkzero Buenas tardes, Dr. Gracias por contestarme. Aunque lo mío es el diseño naval deportivo, tuve gran atracción desde pequeño sobre el funcionamiento del cerebro humano y sus emociones (irónicamente creo poco en la psicología terapéutica, por verla demasiado sujeta a la capacidad y personalidad del terapeuta), como asimismo a diversos temas científicos.
      Desde siempre he tenido la profunda convicción que entre los males que marcan nuestros senderos, la envidia tiene un papel relevante. Y mi planteo tiene que ver con las posibles motivaciones que llevan a una persona, en este caso Doctor (en Física Aplicada?) a dedicar, en forma de youtuber divulgador de ciencias, exponer la irrelevancia del papel que jugó la famosa fórmula de e=m.c2 en la construcción de la 1º bomba atómica.
      En su argumentación expone que su bisabuelo sí tuvo un papel crucial, cosa que no discuto, pero tratando de borrar de un plumazo en ello la figura de Albert Einstein. Este hecho me hace dudar, si su postura es realmente la de un divulgador científico, o, como sospecho, revisionista histórico. Trato de pensar con la frialdad necesaria en mis especulaciones, si en el día de Trinity, en el momento posterior a la prueba, cuando R. Oppenheimer apoyó su cabeza en la almohada de las reflexiones, pensó agradecido en Einstein o por el contrario en su bisabuelo. Y cuando me refiero a la envidia, es la idea que evoca la fantasía de sustituir el segundo por el primero.
      Pareciera que me hubiera alejado del tema, pero mi visión de la vida es un todo, y las matemáticas, a pesar de su enorme aporte, analizan poco (de momento) nuestro comportamiento. Su defensa, por lo leído, gira sobre la base de conclusiones demostrables en la familia de científicos que nos ocupa. Pero apuesto doble contra sencillo que en el fondo de estos conocimientos subyace el ignorar lo obvio. Se parte de cosas ahora elementales en forma inconsciente, como el indiscutible poder de un átomo, la posibilidad de liberación de tal energía y su efecto multiplicador en cadena. Sin esa premisa y su ahora obviedad, seguramente los instintos básicos de los investigadores no les hubieran permitido abordar con tanta rapidez el cómo hacerlo (parafraseando el relato de Eureka).
      Me vi obligado a extenderme en demasía por la complejidad del tema y la dificultad de explicar mis argumentos, como si fuera que 2 + 2 son 4 (bueno... a veces). Tengo varios amigos y familiares en el campo de la investigación, y si algo los comunica y asocia recurrentemente, es su ego (iniciador recíproco del combustible "envidia"). Creo, hablando siempre en términos de mayoría, que esa característica es el motor genuino de tantos esfuerzos.
      ¿Y que tiene que ver todo esto con S. Hawking?. Lo tomé como ejemplo paradigmático de la envidia, incluso en sus comparaciones entre Einstein y Newton (seguramente también influido por antagonismos viscerales nacionalistas: Ingleses vs alemanes), personajes históricos que no deberían compararse, grandes los dos, cada uno en su tema y su tiempo. Me tomo la libertad de sugerirle que vea muchas de sus entrevistas dadas a los medios de información (no a sus pares), para encontrar evidencias de mis afirmaciones.
      Ruego disculpe mi poca capacidad sintáctica. No suelo contestar a las respuestas, por ser RUclips un medio poco idóneo para el mismo, pero por fortuna, muy muy muy cada tanto, hace que pueda encontrarme con personas con quienes vale la pena comunicarse y disfruto al hacerlo. Nuevamente agradecido, lo saludo.

    Einstein was a plagiarist.
    ‘’In 1875, four years before Albert Einstein was born, Samuel Tolver Preston published an amazing book entitled "Physics of the Ether". In it he set down the now famous formula E = mc2 and thoroughly explained its implications. Preston expressly stated that matter contains a store of energy which if fully utilized could create atomic bombs and atomic energy. He knew that atomic energy would someday replace coal. He also described superconductivity and asserted that gravity propagates at light speed. Long before Einstein, Preston completely relativized unipolar induction. His complete works are republished along with commentary and analysis by Christopher Jon Bjerknes who discovered the fact that Preston had anticipated Einstein by many decades and had a better understanding of E = mc2 than Einstein. Albert Einstein mistakenly believed that atomic bombs and atomic energy were impossible to produce.’’

      Einstein was already familiar with E=mc^2, it was an equation that was derived from classical electrodynamics already, before Einstein' published his (and her, his wife was also involved) 'relativistic derivation' of E=mc^2, which contains a fudge factor, so it is not even a correct derivation. That is a strong indication the Einsteins already knew the famous equation before their publication. The Einsteins did not refer to H.A. Lorentz's papers on the 'Lorentz transform', and not to the paper of Waldemar Voigt, who published on a coordinate transform that keeps a wave equation invariant, years before the Einsteins publication, and not to the publication of S.T. Preston. So yes, the Einsteins were plagiarist, since Albert Einstein falsely claimed priority of the E =mc^2 equation. Btw, classical electromagnetism also describes a Poynting vector (an energy flow and momentum flow associated with a TEM wave), but Planck's constant and the Planck relations cannot be derived from classical electromagnetism (yet). So the idea that TEM waves carry energy and momentum was already known before the photon concept.
