Thank you for your instructive videos. I've included 3 hints for the following video on EM waves, i.e., photons; I hope you will like them and agree in some way. 1) A better way to understand EM propagation is by "electromagnetic pulse", not EM waves. This way makes Eintein's Nobel Price intuitive, the EM being compact makes it able to interchange 100% of its momentum and energy with, for example, compact electrons. Photons with a compact EM field with a bigger quantum system, in the same way as compact electrons with a bigger quantum system as needed and seen in the Double slit experiment (big quantum system space that covers both slits but its compact entity can pass through a tiny slit). 2) Also, a pulse defines better the no internal variation of E & B (electric and magnetic fields) as expressed by the relativistic theory; the proper internal time variation in the quantum space is zero (nothing changes at speed C). Meanwhile, Delta t = 0, the passage of time always passes; photons are not eternal, they are created, travel, and interact through time. 3) From Maxwell's equation, the electric and magnetic field, both increments and decrements at the same time; this is an oscillation that corresponds more to a pendulum than a spring oscillation. In an oscillating spring, the kinetic energy of the mass increases meanwhile the internal energy in the spring decreases and vice versa; energy is conserved at all times. In an oscillating pendulum, the kinetic energy of the mass increases meanwhile the gravitational potential energy increases in value, both incrementing (and vice versa); there is no conflict with energy conservation because the potential energy has an opposite sign with the kinetic energy. In the same way, magnetic energy has the opposite sign with respect the electric energy, so both can increase in value and decrease together in time! the great EM wave that Maxwell show to the world. If you are an open mind, I can recommend a short book on Amazon "Space, main actor of quantum and relativistic theories" (an extension of a scientific paper with the same name). Here you can read simple ideas with profound implications, regards

Question: If the magnetic field produces the electric field and vice-versa, why are they represented in phase? I could think as the mag. field converting in el. field and vice-versa, so they should be out of phase: when one increases the other should decrease. Thank you.

[@arpitsharma7495]

no magnetic feild(MF) do not produce electric feilds(EF). but the this shown here is that whenever there is an EF or MF there is always an MF or EF along with it. in certain hypothesis like when charge is at rest(which is not possible) only EF dominate and MF tends to 0.

[@miinyoo]

What I find so curious is who decided to make electromagnetism perfectly perpendicular? It could have been any sort of ratio. Do the weak and strong forces exhibit such bizarre anti-symmetry? Do we really understand them enough to make a judgement about them? I feel like we take a lot of that for granted because it's so hard or nearly impossible to measure directly the axes of interaction. Let's be honest, light and mass therefore energy are the only metrics we have to measure with.

learning need no age if you want to learn you can since this lecture's theory is all of class 12 but the methmatical part is not taught in 12th if you find it interestiong keep your study going it will boost your mind i am also giving 12th boards this year i.e. after 23 all my board exams will be over and around a month later i.e after attempting all competitive exams i will be free to learn all and i will kill it then. so the main thing is keep study going on(more importantly of 12th) if you got spare time then you should focus on QM

What if we describe subatomic particles as spatial curvature, instead of trying to describe General Relativity as being mediated by particles? Quantum Entangled Twisted Tubules: "A theory that you can't explain to a bartender is probably no damn good." Ernest Rutherford 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? 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 Force" 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. 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 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. Gamma photons are produced when a tube unwinds producing electromagnetic waves. >>>>>>>>>>>>>>>>>>>>>> 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. 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?

[@basharatmalik2004]

Sir hope you are doing well. If a quantity say x is directly proportional to another quantity y, does it imply that y is also proportional to x. Sir shouldn't the friction be due to intermolecular forces of repulsion and not attraction۔ Because if the contact forces are attractive ،they would have no component perpendicular to the surface to balance attractive gravitational force. Please sir or anyone else، do comment on the questions. Thank you
