Here I am, an MBA student at Lehigh University specializing in data analytics, more than captivated at a lecture over 40 years old: a lecture that is so much better than any I’ve had, ever. What an incredible teacher.

[@DavidMcMillan888]

Yes, calling Einstein crap is a bit strong. His only major error was his “cosmological constant”, of which he termed his ‘greatest blunder’ There’s a strong temptation for people to welcome every claim that all historical discoveries are mistakes but if the maths holds with observations, we should accept theories that stand testing as with Einstein

[@schmetterling4477]

I have never heard a better teacher: one of the most brilliant minds ever, but perhaps his true incandescence was his ability to comprehend the layman's mind and make this bizarre world accessible to many.

[@Eztoez]

He was a teacher of teachers. Esteemed university professors used to drop what they were doing and gatecrash his lectures, listening to the Master as if they were hearing concepts for the first time.

[@johnwest7993]

His true beauty was that he HAD a layman's mind, just one that worked to see more clearly, and one that would accept everything exactly as it was, not as he wished or assumed it to be.

THE ULTIMATE AND CLEAR MATHEMATICAL PROOF OF THE FACT THAT E=MC2 IS F=MA: Ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. SO, time DILATION ULTIMATELY proves ON BALANCE that E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Great !!! "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=MC2 IS F=MA. Consider the man who IS standing on what is the EARTH/ground. Touch AND feeling BLEND, as ELECTROMAGNETISM/energy is gravity; as E=mc2 IS F=ma. GREAT !!! E=mc2 IS F=ma. The linked AND BALANCED opposite of what is THE SUN is A POINT in the night sky. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Therefore, the linked AND BALANCED opposite of what is THE EARTH is ALSO A POINT in the night sky. Great. Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the Earth AND the Sun are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy, AS E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. It ALL CLEARLY makes perfect sense. Great !!!!!! Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. E=MC2 IS F=MA. The EARTH and the SUN thus constitute and comprise what are the MIDDLE AND THE FULL DISTANCE in/of SPACE (IN BALANCE) in full and BALANCED compliance and conformity with the CLEAR and universal fact that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great !!!! It ALL CLEARLY does make perfect sense. (The stars AND PLANETS are POINTS in the night sky.) INDEED, BALANCE and completeness go hand in hand. Now, very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. Great. NOW, OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. Notice the black space of THE EYE. The stars AND PLANETS are POINTS in the night sky. THE DOME of a person's EYE is ALSO VISIBLE. Now, carefully consider what is the semi-spherical, translucent, QUANTUM GRAVITATIONAL, AND BLUE SKY. Great. E=mc2 IS F=ma. It is CLEAR. THE EARTH is ALSO BLUE (AS WATER). GREAT. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, as E=mc2 IS F=ma; as ELECTROMAGNETISM/energy is gravity. Gravity IS ELECTROMAGNETISM/energy. It ALL CLEARLY makes perfect sense. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/energy, as this unifies AND balances gravity AND ELECTROMAGNETISM/energy; as this balances gravity AND inertia. (This clearly explains BOTH F=ma AND E=mc2, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!!) ACCORDINGLY, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, the BALANCE of being AND EXPERIENCE is essential; AS E=mc2 IS F=ma. Our EXPERIENCE is NECESSARILY that of what is the FULL DISTANCE in/of SPACE, AS we are BALANCED between what are THE SUN AND c (A POINT); AS E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. SO, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/as F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. BALANCE and completeness go hand in hand. It ALL CLEARLY does make perfect sense. THINK about what is QUANTUM GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Therefore, the rotation of WHAT IS THE MOON matches it's revolution !!! Objects fall at the SAME RATE (neglecting air resistance, of course), AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. Gravitational force/ENERGY is proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Stellar clustering ALSO proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=mc2 IS F=ma. Magnificent !!! E=mc2 IS F=ma. Is a two dimensional surface or SPACE visible or invisible ? The answer is that it is BOTH. So, the electron AND photon are structureless. A PLANET (INCLUDING WHAT IS THE EARTH) is a balanced MIDDLE DISTANCE form in relation to E=mc2 AS F=ma. A PLANET (INCLUDING WHAT IS THE EARTH) is a balanced MIDDLE DISTANCE form in relation to the Sun AND c (A POINT). The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=MA. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. BALANCE AND completeness go hand in hand. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. E=MC2 IS F=MA. It ALL CLEARLY makes perfect sense. The BALANCE of being AND EXPERIENCE is essential. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience. (THOUGHTS ARE INVISIBLE.) It is a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. Beautiful. It ALL CLEARLY makes perfect sense. E=mc2 IS F=ma. By Frank Martin DiMeglio

If E=MC^2 was the same as F=MA then nothing about relativistic movement makes sense. For example, Mercury's orbit no longer makes sense. But Einstein's relativity allowed us to make accurate predictions about Mercury's orbit, something that was not possible before.

One true sign of genius is the ability to take an enormously difficult topic, like quantum physics, and simplify it to such a degree that most people, who are not scientists, can begin to understand it. Yes, teaching is just as important as discovery. Professor Feynman rips apart the false adage 'if you can't do, teach.' Of what use is to have the gift of discovering great ideas if you don't have the gift of communicating those ideas to others? Professor Feynman had both of these extremely rare gifts. Truly a giant.

It's funny how folks at these lectures can't seem to come up with good questions. Here are some questions I would have liked to ask him. Granted, people in the audience may not have the ability to ask detailed questions, but still.... "When you see something, is it the light from the object that you see, or is it the object that you see?" Come on. Clearly the object is actually jumping into your eyeball. Anyway, if anyone knows the answers, feel free to answer, please. Regarding the interaction of reflections from 2 different surfaces: Suppose your 2 surfaces are a very large distance apart - say, one light-second apart, but still positioned just right so your photons destructively interfere. Should you expect to get a reflection for 2 seconds - the time it would take for photons returning from the far surface to return and interfere with the photons from the first surface? The way Feynman describes it, you should get no reflection at all, and there would have to be some instantaneous information transmission. If whether or not the photons constructively or destructively interfere is actually due to an aggregation of reflections throughout the substance, and not actually due to the existence of the "surfaces," which are actually a sort of fiction, then why can't you ever get destructive interference of photons if the detector is below the first "surface?" I.e., inside the substance (and, as in the case of the detector outside the substance, if photons are only allowed to approach the detector from below). Also, when your detector is inside the substance, why are no photons detected coming from anywhere but the bottom "surface?" Maybe destructive interference is responsible for this, but not at all as explained as in the case of the detector outside, and certainly not dependent on the detector's distance from the bottom "surface." If photons are individual particles, what is the duration of a photon? To illustrate what I mean, consider an extremely low frequency photon - a photon having a wavelength of, for example, one light-minute. Now, supposing you can control the time and direction at which the photon is emitted, you send this photon through an aperture which you are capable of dilating and contracting. At the time at which the photon reaches the aperture, the aperture is large enough to admit the photon. Before one minute has elapsed, suppose, at 30 seconds, the aperture is contracted to a size that the photon cannot move through. Does the photon get through? Is the photon detectable only between the aperture and 30 light seconds beyond it? How quickly can you close the aperture and still allow the photon to pass if the answer is not one minute? Or, does the photon have no transverse length, and always pass, provided the aperture is of a size that would permit the photon to pass at the moment when the photon reaches it? And if this is the case, then how is the information of wavelength carried by the photon? There is a good PSSC video about the experiment that demonstrates that light is made up of particles (which Feynman references) done by John King that illustrates the principles of that experiment very well, but the aperture size and duration in that experiment was nowhere near the scale of the wavelength and frequency of the light investigated. I suspect that the answer is that 100% of the photons get through when it takes 1 minute to close, 50% get through when it takes 30 seconds and so on, because, I suspect, the order of the size of the aperture at which 100% of the photons pass is 1 light-minute in diameter, which limits how quickly you can close the aperture sufficiently, which is maddeningly unsatisfying. Well thanks to anyone who read this far. I think that's enough questions for one post.

I always thought of it this way: Biologist sweats when she learns biology is just chemistry at a large scale...... Chemist sweats when he learns chemistry is just the physics of atoms and their electrons...... Physicists sweat when they learn physics is the application of mathematics to matter...... Mathematicians explain their theories to us and we can't understand a thing because we're biological creatures......

Readers who like Physics. Can you understand this post on the concept of Dimp, the dimensionlesspoint, I am struggling to explain it clearly. This from the next Musea. 1. DIMP stands for dimensionless point - DIM-ensionless P-oint . This is a single point outside the universe, that contains all light! This is a challenging concept and difficult to even imagine. How can anything, let alone all that, be in a point without dimensions? But it's based on what we know now. When you understand my single concept of DIMP, the rest of these physics ideas fall into place. So I will try to explain it in a couple of ways. Read, this section carefully! Dimp or the dimensionless point is a single point that contains all PHOTONS. (For visual purposes, think of photons as little pieces of light.) That means Dimp contains all ELECTROMAGNETIC ENERGY in a single dimensionless point. That means all light is in a single point, a point that doesn't have four dimensions, or three, or two, or even one! Pauli's Exclusion Principle is a clue. It says all photons ( a type of boson), can be in one point while their counterpart, fermions, cannot. Remember a PHOTON DOES NOT OCCUPY SPACE! There is no limit to how many can occupy the same quantum state. Photons, all of them, can be in a single point! By definition we know that photons are outside of time and distance. Infinite time dilation (no time) goes hand in hand with infinite length contraction (no distance to the destination). Because a photon is outside time, it is eternal. Because a photon is outside distance, there is no distance between any two photons. They are all together in an eternal point. They share a dimensionless point! That means all light is in one point. If there is no distance than photons are everywhere at once - or everywhere at once and back! That means that the photons in the singularity that started the big bang and our entire universe, are here now today, and will be here forever in the future. Here's an official quote from Physics org: From the perspective of a photon, there is no such thing as time... It doesn't experience distance either. My idea that all light energy is gathered in Dimp, a single dimensionless point, eternal and outside of space-time, is not easy to comprehend. Let's try this visual analogy. Look at photons, not as individual particles or waves of light, but as a quantum ENERGY FIELD that is everywhere at once, a BLANKET OF LIGHT that surrounds everything in the universe and is in every part of space time at the same time. Still with me? Because Dimp is eternal and outside time; that means Dimp is these things: 1. Here before the Big Bang, during the Big Bang, and here long after this universe will have ended. A vast reservoir of all energy. And our universe, where there is space and time, is a small subset of Dimp, just as an ember is a small subset of a massive bonfire. Dimp was the singularity, the dimensionless point, that the Big Bang exploded out of. That means Dimp is separate from, not only time and distance, but gravity, mass, space, you name it! There is no acceleration in DIMP therefore no gravity!. There is no expansion in DIMP and no charge. Further the virtually endless amount of energy in Dimp never changes. That is some weird point! Dimp, the dimensionless point concept seems to explain all the following separate concepts; COSMOLOGICAL CONSTANT, ZERO POINT ENERGY, VIRTUAL PARTICLES, ENTANGLEMENT OR 'SPOOKY ACTION AT A DISTANCE', AND VACUUM ENERGY. Dimp also means the electromagnetic force and force of gravity (see later) are not connected. They are separate and can't be unified. The simplest way to explain Dimp is to start by saying, there are TWO UNIVERSES. THE FIRST UNIVERSE is DIMP, the dimensionless point, or the universe of photons, light, and energy, where everything that is, goes the "speed of light". THE SECOND UNIVERSE is SPACE - TIME where everything goes slower than the speed of light. This is the universe of everything that is - BUT photons. Nothing in Dimp goes slower than the speed of light. Nothing in the universe goes the speed of light. Does that help clarify? BUT WAIT, it gets more strange... The problem is that to have a "speed of light" one has to have both time and distance. But a photon from it's point of view is outside of both time and distance. From our space-time point of view it looks like photons are going a set distance in a set time, but that is our illusion, not their fact. So "speed of light" is a misnomer. More about this puzzle later. . Physics often uncovers a dark zone of unexplained phenomenon. Dimp may help explain those dark zones including: 1. The singularity where the big bang began. 2. Dimp, the dimensionless point of all photons, all light. 3. The dark area in an atom during a quantum jump where the electron instantly jumps over, when it jumps from shell to shell. " Everything in the quantum mechanical universe ... happens in quantum leaps. A quantum leap is a discontinuous transit between quantum states - an electron jumps instantly into another energy level... There is no in between state and it doesn't take anytime for the leap to occur." Moring. 4. The empty zone in an atom where the electron orbital is not. 5. The Two Slit Experiment black bands where no particles/waves land. 6. The nodes of waves where the particle probability is zero. 7. When two mirror image waves collide, constructive interference occurs which annihilates both waves, and turns them into pure energy. Dimp is that pure energy. 8. Virtual Particles where particle A and Particle B pop up out of the void, then come together and there is total annihilation. 9. Quantum tunneling? The space between when Particle A disappears on one side and materializes on the other side. 10. Entangled particles where A and B are strangely and instantly connected no matter the distance between them. 11. Force carriers. 12. the infinities that renormalization tries to fix. With Dimp they are correct as is. 13. Wheeler's Great Smoky Dragon analogy, where A is the head of the dragon, B is the tail of the dragon and the area between is smoke. 14. The 120 orders of magnitude of the vacuum energy density or cosmological constant. 15. Non locality may also be explained by Dimp which is outside of time and space. Where is Dimp? Everywhere that there is vacuum energy or space, or everywhere!That's because any surface not at absolute zero emits photons, and absolute zero can't be reached. It"s both outside and inside space time! But wait - more weirdness: PHOTONS DON'T GO ANYWHERE. Remember the speed of light problem? Photons do not move out of dimp! If they did they would have time and distance, which they do not! Photons pop out of Dimp. They are created out of Dimp and return to Dimp. Text books say, the only interactions a photon has, are to be created or destroyed. We see a photon being created or destroyed, but nothing in between! Through pair conversion they send MESSENGERS: Electron / Positron pairs as the energy to do the work . That suggests that electrons and positrons are vehicles for photon energy! That means when a photon pops up in our universe, it does so only as an electron / positron pair! We know that as an object approaches the speed of light it: becomes heavier and approaches infinite mass, (Infinite mass is also infinite energy, E=MC2). It contracts in length, and time slows. Could that object keep going faster, it would reach the speed of light and be outside of time and be eternal. SO if mass could go the speed of light (and it can only approach it) it would be infinite energy with no length in a single dimensionless point, outside of time! Sound familiar? That is DIMP! Totally confused? Take a break and try this visual exercise: The light from all stars shine out in every direction with eternal photons that are everywhere all at once. Look, a web of photons connect all space and all time, now and forever - a net of light!
