    You got my sub because you got my attention. This is what makes you a good teacher: Most of my teachers in school would teach the equation and explain how it works, but when you physically show what the equation is actually doing and physically show the relationship of the equations, it gives me a better understanding.

    In _Principles of electrodynamics_ by Melvin Schwartz, Maxwell's equations are derived via the Lorentz invariance. "We will assume that the force on a charged particle in its own rest frame is given by the electric field as the particle sees it. Furthermore, we will assume that if the charge and current distributions that it sees in its own rest frame are not changing with time, then the electric field it sees will be determined, just as in the case of simple electrostatics, by [Gauss' law]. The consequences of these innocent-sounding assumptions are absolutely fantastic. We will now show that the electric field cannot provide a complete description of the long-range forces resulting from charges and currents, but that there must in addition be other field quantities at each point in space which exert a velocity-dependent force on a moving charged particle. Thus we will deduce that there must be a magnetic type of force. Later we shall see how to express this force in terms of magnetic field."

      By the way, that might also explain why gravity acceleration does not cause a charged particle to radiate. That is, the particle and its field have the same rest frame as gravity "pulls" _everything_ at the same rate. On the other hand, electrostatic force affects only the particle, not its field, and that causes "friction" and radiation.

      @@xjuhox i strongly suspect that time for changes in the electric field need to be accounted, rather than to jump to the magnetic fields within a charges frame of reference, because a magnetic field in a lab reference is nothing but an electric field in a charge's frame of reference.
      For Example, suppose you have two neutral wires in the lab reference frame adjacent to each other, with current flowing in both, in opposite directions. Now, Lets take a single electron in one wire and use it's reference frame. It doesn't see magnetic fields period, It can only see electric fields. It sees electric fields near by and electric fields in the other wire. Given the relative velocity of electrons and protons in the other wire as seen by our electron and factoring einstein's relativity length contraction (L=L'sqrt(1-v²tc²)), results in a greater electron length contraction and a greater negative electric field in the other wire, so our electron is repulsed by the negative electric field coming from the ther wire as seen by our electron's reference frame.
      In short, Einstein's relativity and different reference frames binds electric and magnetic fields into electromagnetism.
      Yes I know the average drift velocity of electrons in a 22 guage wire with 10 amos is low about 0.056 mililimeters per second more or less, but force between the two wires only testifies to the strength of the electric field and the great number of electrons involved.

      ​​​@@xjuhoxwhen a charged particle is perturbed, it "irradia"tes the information of its field to its sourrondings, that is the definition of "radia"tion (action on the radial direction). The "radia"l field lines are "irradia"ted (not radial anymore) ...as Responsable - Ir-responsable.
      So, in the case of a charged partcile falling due to gravity nearby the surface of the earth, that irradiated rectilinear pulse (not a wave) is felt "instantly" or within a second of delay by charged particles located less than 300000 km away (Having the frame on the surface of the earth)
      If the particle bounces, then irradiates a wavelet pulse (geometrically speaking) until it rests.

    It's been years since I was a physics major. I didn't graduate but I do remember things like Amperes' Law, Lenze's Law, and the Maxwell equations. That link between the two fields you mentioned, namely the mathematics establishing a link between the electric and the magnetic fields was the key and was interesting. And I believe that Einstein, observing that the same voltage was induced whether he moved a magnet relative to a wire loop or if you moved the wire loop relative to the magnetic in the lab, was nature whispering to him that no experiment could ever be performed that would betray absolute motion. That observation led to one of Einstein's postulates of special relativity, namely that: " Absolute uniform motion cannot be detected ". Put another way, there's no place in space upon which an origin of coordinates can be fixed.

    Also do remember that u0 and e0 are measurable attributes of vacuum. That suggests that vacuum is filled with u0, e0 and hence a medium some call it Aether.
    From the start we were under an impression that Aether exists as wind that blows through all matter. And the M&M design of experiment was based on such assumption.
    It is also important to appreciate that no medium for no seismic wave, no air for no sound, no strings vibration for no music. Likewise no e0, u0, or Aether for no E,B radiation or no light.

    Maxwell: discovered the physics of (special) relativity.
    Einstein: invented the paradigm of relativity.
    It is interesting to notice how Maxwell's equations alone give all the phenomena of relativity, like time dilation and length contraction. But the few physicists who discovered those phenomena (although mostly in a non-constructive way), and came up with the right coordinate transformations to get the frame adopted by a moving device, still considered those coordinates to be less "real" than the coordinates of a frame at absolute rest. And although this rest frame could not be detected they kept giving explanations describing how this frame conspires to remain undetectable. It took Einstein to recognise that it was pointless to keep talking about an absolute frame in physics. With this regard I consider him more influential than Maxwell, since he founded the paradigm for theoretical physics, while Maxwell was still thinking in a classical paradigm of absolute space and time. But yes, apparently Maxwell was the first one to give a complete theory of non-gravitational physics.
    Another interesting notice is that classical mechanics is completely compatible with relativity, as long as all the forces are local, and fundamentally described by electromagnetism, despite common pedagogy erroneously tends to talk about a contrast in the description of the phenomena rather than paradigm. On this topic there is an interesting paper by John Bell, "how to teach special relativity", on stressing the importance for a "Lorentzian pedagogy".

Then one photon si part of height of this wave(like smallest possible part)? One slice of this wave like a one sample? We can show signal on oscliloscope, but its many phototos, what part of triggered sampled wave on screen is one emmited photon? I see many videos, but still have a big confusion about this. And second question, photon energy is depend directly on wavelength, but it can be lowered or incresed by relative motion - doopler effect, universe expansion - where energy loss goes? Because energy must be conservated.... 🙂

    Maxwell was just such an astounding genius. One of the last true Renaissance Men whose genius was applied in so many different realms. Besides electromagnetism, he investigated kinetic theory and thermodynamics, the psychology of color perception (he made the first durable color photo!), and control theory (which at the time was related to governors on steam engines, which was as close as you could get to automation and cybernetics in the 1800s, lol)
    He wrote poetry and played the guitar. In another age, he might have been a rock and roll star, lol

    That are against of energy conservation, since at each semi cycle both fields vanishes.
    But if the both fields intensity were at 90° the energy never vanishes and mantain a constant intensity.
    This have more implication relative at if the wave has a medium of propagation or not.

      How does your special relativity explains emergence of magnetic field around one moving proton? Let's assume Maxwell equations are right. Please, explain. One moving proton. Not an electric current because then you will use that rubish explanation about length contraction. I think most physicists don't get what lenght contraction is about. Actual elelectric density doesn't change. You have a moving object which is longer in its rest frame but only in units. Units that are contracted comparing to original non moving frame of reference. Real density doesn't change.

    The speed of light is not a constant speed as once thought, and this has now been proved by Electrodynamic theory and by Experiments done by many independent researchers. The results clearly show that light propagates instantaneously when it is created by a source, and reduces to approximately the speed of light in the farfield, about one wavelength from the source, and never becomes equal to exactly c. This corresponds the phase speed, group speed, and information speed. Any theory assuming the speed of light is a constant, such as Special Relativity and General Relativity are wrong, and it has implications to Quantum theories as well. So this fact about the speed of light affects all of Modern Physics. Often it is stated that Relativity has been verified by so many experiments, how can it be wrong. Well no experiment can prove a theory, and can only provide evidence that a theory is correct. But one experiment can absolutely disprove a theory, and the new speed of light experiments proving the speed of light is not a constant is such a proof. So what does it mean? Well a derivation of Relativity using instantaneous nearfield light yields Galilean Relativity. This can easily seen by inserting c=infinity into the Lorentz Transform, yielding the Galilean Transform, where time is the same in all inertial frames. So a moving object observed with instantaneous nearfield light will yield no Relativistic effects, whereas by changing the frequency of the light such that farfield light is used will observe Relativistic effects. But since time and space are real and independent of the frequency of light used to measure its effects, then one must conclude the effects of Relativity are just an optical illusion.
    Since General Relativity is based on Special Relativity, then it has the same problem. A better theory of Gravity is Gravitoelectromagnetism which assumes gravity can be mathematically described by 4 Maxwell equations, similar to to those of electromagnetic theory. It is well known that General Relativity reduces to Gravitoelectromagnetism for weak fields, which is all that we observe. Using this theory, analysis of an oscillating mass yields a wave equation set equal to a source term. Analysis of this equation shows that the phase speed, group speed, and information speed are instantaneous in the nearfield and reduce to the speed of light in the farfield. This theory then accounts for all the observed gravitational effects including instantaneous nearfield and the speed of light farfield. The main difference is that this theory is a field theory, and not a geometrical theory like General Relativity. Because it is a field theory, Gravity can be then be quantized as the Graviton.
    Lastly it should be mentioned that this research shows that the Pilot Wave interpretation of Quantum Mechanics can no longer be criticized for requiring instantaneous interaction of the pilot wave, thereby violating Relativity. It should also be noted that nearfield electromagnetic fields can be explained by quantum mechanics using the Pilot Wave interpretation of quantum mechanics and the Heisenberg uncertainty principle (HUP), where Δx and Δp are interpreted as averages, and not the uncertainty in the values as in other interpretations of quantum mechanics. So in HUP: Δx Δp = h, where Δp=mΔv, and m is an effective mass due to momentum, thus HUP becomes: Δx Δv = h/m. In the nearfield where the field is created, Δx=0, therefore Δv=infinity. In the farfield, HUP: Δx Δp = h, where p = h/λ. HUP then becomes: Δx h/λ = h, or Δx=λ. Also in the farfield HUP becomes: λmΔv=h, thus Δv=h/(mλ). Since p=h/λ, then Δv=p/m. Also since p=mc, then Δv=c. So in summary, in the nearfield Δv=infinity, and in the farfield Δv=c, where Δv is the average velocity of the photon according to Pilot Wave theory. Consequently the Pilot wave interpretation should become the preferred interpretation of Quantum Mechanics. It should also be noted that this argument can be applied to all fields, including the graviton. Hence all fields should exhibit instantaneous nearfield and speed c farfield behavior, and this can explain the non-local effects observed in quantum entangled particles.

    This clearly proves that truth is not something even science can define. Because everything we do in physics and math are defined according to our philosophy. We create the definitions and also the axioms based on our philosophy. Just because the value is equal to the value we think that belongs to light speed shows us that we just never found the truth rather we defined it as a good or sufficient condition and made the world think we are saying the truth. I am a mathematician who follows structuralism and when I see theoretical phycists expresses their idea as truth just because it is working make me laugh. That's why these guys don't understand math and engineering even still now and thinks we are discovering math but what we do is we create system, where there exist consistent ideas that just simply works with our system. I am happy that I understood this and pursued math not the theoretical physics who constantly fights for if one's idea is either true or false, just to become a huge hero but after some decades when people will find the idea was wrong and throw him away to ashes and would also curse him for insisting people that he was true and would never take carr of his descendants will be the saddest story of his family's life but here I can just work and be happy and have time to praise my creator all the time and don't have worry about being famous because I know what I am doing is just inventing different ideas with the help of philosophy and logic and just creating ways by creating relationships with distinguishable ideas so that people can work with in some way at least using pen and paper makes me feel confident. Philosophy and logic taught me one thing that is direct proof is the only way to say something true, whenever indirect proof arises we can't say if something is either true or false then it becomes probabilistic. Human's direct proof is his senses, not the tools or subjects humans create. Have peace in mind people. When i saw the youtuber being emotionally driven towards the scientists he was talking about, I felt sad because that is how you become biased and lose the peace of your mind. Pride is not what we humans should search for rather, we should always be grateful towards our creator all the time because he is the one who can distinguish truth and false without any doubt. This distinguishable power wasn't given to us.

Angular momentum is analogous to a real cause based in accelerations. Look at my latest video that explains the creation of accelerations that have nothing to do with spinning but the rate that it creates for the cause.

    the claim that quaternions and tensors yield the same result is not true. Example: (1) Start with a 4vector potential. No matter what you do, in the end you end up with a 3vector electric and a 3vector magnetic field. You lose one component. You have Gauge Freedom now. Which means your equations are underdetermined, so you have to introduce an auxiliary condition, called the gauge, completely at your disposal. Yes, I do know it's a Faraday Tensor, but if you keep time intact, it behaves as a 3vector, since the tensor components at hand are the i0 and 0i ones. (2) Start with a quaternion potential. Similar to the 4vector potential, the quaternion potential has 4 components as well. Now, no matter what you do to this quaternion potential, you end up with another quaternion. You still end up with a 4D solution. If you want a 3D solution, you have to forcibly declare the time component of the quaternion potential to be zero. This is artificial of course and will transform under a coordinate transformation back to a proper 4 component quaternion. So no matter what you do, you end up with another quaternion, not with a terzion. So you see, there is a difference between the tensor and the quaternion formalism. Yes, we are all taught that quaternions and vectors can be transformed one into another, just that quaternions are more complicated. But clearly there is something else at play. This is the basis of Tesla's work on Scalar Waves. These do not exists in the Helmholtz tensor electromagnetism. I have seen a CIA document "explaining" Tesla's work by assuming there is a longitudinal wave, and then transforming it back to no longitudinal wave, concluding that Tesla was wrong. The CIA guy did it all in the tensor formalism. Not realising that whatever you do with tensors, you end up in 3D. Instead, he should have done it with quaternions, but that is not being taught any more. Also, the transformations we use between tensors and quaternions is probably flawed somewhere: we do prove that tensors and quaternions yield the same results. Which is false by doing the entire thing with quaternions only. No one touches this for the past century and more. Except Tesla, who was cut off completely. Tunguska in 1908 was probably his doing... which means there is something to it. He probably created standing electrowaves between Earth and the Ionosphere: probably an oscillating circle, with ionosphere and Earth acting as conducting plates, the lightning path being zig-zag, hence like a solenoid connecting Ionosphere and Earth, with current running from low to a lot and back to low, bouncing between Earth and Ionosphere "plates", and there you have it. I have also seen a more complicated attempts at explaining what Tesla wanted to do with Earth and Ionosphere. But it doesn't get any simpler than the oscillating circuit I guess. So he was cut off probably for this. It is free energy for everyone. Finally, all our solutions and equations depend on the mathematics we have invented so far. General Relativity would be impossible without Riemann spaces. Quantum theory without Hilbert spaces and Fourier transforms. And so on. We blindly believe we have all mathematics there is. Which is not true. We need new mathematical tools next. Oh, and your electric field video that cannot reach the conclusion: yes, there is the problem with the tensor description of electromagnetism. Tensors don't work well with vector products. Tensors do not vanish under coordinate transformation, ever. There are no ghosts with tensors. And yet, there are coordinate systems where any vector product vanishes: just stop the rotation. And magnetism comes from the vector product... Laterz! Keep posting please!

    I am an PhD physicist and the analysis presented in this video is wrong! EM fields are created by sources and they cannot be set to zero when sources are present. Setting the sources to zero is only valid at infinite distance from the source which does not exist in this universe. Including the source terms yields a wave equation equal to a source term and solving this inhomogeneous PDE is much more difficult, but it has been done by many researchers. Extracting the phase vs distance relation for an oscillating source and applying phase speed and group speed operators (inversely proportional to the slope of the curve), shows that the speed of the fields are instantaneous in the nearfield and reduces to about speed c after propagating 1 wavelength from the source. As they continue to propagate, the speed continues to get closer to speed c, but never becomes exactly speed c, even at astronautical distance from the source, confirming my initial statement. So the speed of light is not a constant and this disproves the 2nd postulate of Relativity, and what remains is only the 1st postulate: Galilean Relativity, where time and space are absolute and not flexible as Relativity suggests. So Relativity is wrong, and this also disproves GR which is based on it, and it has consequences for all of modern physics, see my comment below. The last paper linked in my comment below shows a recent experiment where an EM pulse propagated in a lab without any observed propagation delay. This shows that the front speed, or the speed of information is instantaneous in the nearfield, and absolutely disproves Relativity. This paper has been peer reviewed and will be published ~October in the EM Journal IRECAP.

I don't really like the quantum field theory but they use the same logic applied to bosons as well. They are not literally waves, but they behave almost the same. Yeah I still don't like it very much.

    How can mature people say such nonsense? Fairy tales for children.

    The information is definitely valuable, but what's the point of making these videos with such a thick English accent spoken at .78 speed? There are a million videos on the same topic out there already with young smiling and ambitious science men, this piece of content hardly sheds light on anything new or in a novel manner.

      Link the videos then. I have seen my fair share and I have yet to see them talk about the history

      You're calling that an English accent? Sounds Czechian to me.

    ight can travel through water for 100 years, but when it goes out into the air, the speed increases. How is it possible without ether.

      There is a great 3blue 1brown video explaining this phenomenon I think it’s in his optics puzzles series. In short the light, though of as a sin wave traveled at speed c when it enters a medium the electromagnetic waves cause the particles of the medium to oscillate creating their own electromagnetic field which interferes deconstructive the resulting sine wave of the initial electromagnetic field is the same but with an incredibly small negative phase shift, this happens for every particle in the medium. The resulting sine wave has a shorter period and to maintain its frequency it slows down. when it exits the medium it’s still the same sine wave just with a slightly shifted phase

    Maxvell has written 20 Statements but Einstein and Company has reduce on a 4.

      Heaviside reduced it to 4 when Einstein was around 5 years old.
      Light never travels slower than c. The effective velocity in a medium is due to interference of the incident wave and the waves emitted by the medium. See group velocity and phase velocity.
      When the light exits the medium there is no more waves emitted from the medium and the interference stops, so the phase velocity and group velocity are equal.
