Veepee33 Hey....physics give shape to mathematics...if you inspect closer, you'll find that pure mathematics is abstract and meaningless...but when it is applied in physics, then its beauty comes out!!!
A number of years ago when I was about 50 years old I became interested in physics and discovered that the there is a language, called mathematics, to understand that body of knowledge. I started taking lower division classes in calculus and physics at the local community college-thinking that I would understand such concepts like Maxwell's equations. I found that it was not quite that simple so I began taking classes in physics and ODE's, PDE's, linear algebra, etc at the university. Much of it was a struggle-I made a C- in EM for instance (See Hitler's rant on RUclips when he finds that he flunks his coarse in EM- I understand completely-even being confused by Griffiths r notation). But have reached a point where I can appreciate, understand and enjoy these concepts as presented by DrPhysicsA lectures, such as his one on Maxwell's equations and this one-"What is light?'. These lectures bring all of the efforts that I've made worth while. These lecture are clear and concise-without being dumbed it down. Thanks!!!
You sir, are simply amazing. Awesome teaching skills and simplicity in teaching others very complex stuff. You made me understand maxwell's equations better than anyone. Not to mention the other stuff you got here on nuclear physics and everything else. Awesome teacher, you sir deserve a medal!!!!!
Unbelievably awesome. I am in constant awe of your continuing ability to clarify and inspire what others can only seem to obfuscate and discourage. My hat off to you, good sir, please keep a steady stream of these gems a-comin!
I'm finishing high school but i'm always curious about physics, and so i was having problems understanding electro-magnetic waves but that video was absolutely explanatory. Thanks a lot for all your videos you deserve a lot more than 1,5 million views and i'm sure you will get it.
This particular series will look at electromagnetic radiation derived from Maxwell's equations. As I said in a comment below, Maxwell would not have been aware of quantum physics. His equations still hold true. But as you say, there is now another way to look at all this through the quantum mechanical approach.
What a fantastic explanation. I have look far and wide for an "intuitive" explanation on how EM waves are actually created, and how they can go from an oscillating charge to a wave. Great job on all of your videos; they are extremely informative!
You are quite right. The series of videos I am making at the moment derive electromagnetic radiation from Maxwell's equations. Maxwell was, of course, completely unaware of anything to do with quantum physics. So this is simply explaining the situation from his perspective which is a perfectly proper thing to do. We now know that light can also be considered to be made up of photons which are packets of energy. That is the quantum mechanical approach which I am not covering in this series.
d/dt Means a differentiation with respect to time. Essentially we are asking how does some function vary over a very short space of time. This is covered in a mathematics calculus course.
All of the material which will be contained in my current series on electromagnetic radiation as a quantum mechanical dimensional which I shall not be covering. My purpose in this series is simply to show how Maxwell's equations can be used to derive the various phenomena associated with electromagnetic radiation. But you are right, that there is a whole new dimensional when we get to quantum physics.
I want to learn how to do this 0:261:06 :D great video thank you for making this subject accessible, my book is intimidating and this explanation and the tutorial on maxwell equation has been extremely helpful and saved me a lot of time in exam prep
Who measured the speed of light? Sounds silly to me, there's no constant speed of light, it changes according to the medium in which it travels through. There is no speed of light, it is a rate of induction!
continued -- From that microwave photon link, a microwave photon has a lower power level than a visible-light photon, but what about size? Is a microwave photon bigger in size (volume) than a visible light photon? Is it the same shape (one is generated from the up/down on an antenna, the other from an energy drop)? Can you discuss optical antennas? I realize that this is a long list of questions, but I know you're looking for feedback. Again, thanks for producing your videos.
Here is a simple way of looking at it : Curl of E = -dB/dt (negative sign is less relevant here) As E exists solely in the x-direction, Curl of E = dE/dz y (a y vector with a magnitude dE/dz) Conclusion 1: B is in the y-direction. Simply put, dE/dz = dB/dt Now, we consolidate the fact that differential equations of E and B are w.r.t different variables dz and dt. Since dB/dt = dB/dz · dz/dt, dE/dz = dB/dz · dz/dt dE/dz = dB/dz · c Conclusion: rate of change of E wrt to z is identical to that of B. Since E wrt to z is sinusoidal, wave B is sinusoidal and entirely in phase with wave E. In addition, E is larger in magnitude by a multiple of c.
Another worthwhile video, good job. I'm looking forward to the whole series on light. At some point, could you discuss what is, and is not, known about the link between an electromagnetic wave and photons? Can you draw a picture of a photon (is it a "wave packet", burst, something else)? I can't post a link, but if you Google "Breakthrough for photons in the microwave frequency range", it discusses the generation and detection of microwave photons. Can you explain what they are doing?
A photon is just a made up term by quantum physicists or bean counters. A photon is a scalar pulse (longitudinal wave), a dielectric pulse or condensate, like a burst of energy where the transverse dielectric and the longitudinal magnetic intersect. There is no such thing as a photon. Electrons on the outer shell of an atom are simply a measure of magnetism or level of magnetism. An electron is one unit of dielectric induction. An atom is an electro-static dynamo.
If the electron can oscillate continuosly and generate a continuos wave? Energy is transmitted in packet (photon). How many electron oscillation needs to generate a photon? When a photon is generated then the electron stops? Who make it restart? (The same principle also apply to black body radiation?)
There's no such thing as photon, it's simply a fabrication by quantum physicists. A photon as commonly known is a scalar pulse, a dielectric or electro-static pulse (longitudinal dielectric condensate). I do not use the word photons, they are not particles, can you shake the photons out of your photographic equipment?
At 2:25, where you showed the cross product or curl of the vector, was that the determinant you took to get that expression? If so, isn't the second expression supposed to be negative? I.e., x-hat minus y-hat plus z-hat?
Hi Doc, are you saying that light is the discrepancy between 2 frames of reference: the one that measures a particle(ex electron) and the one that has not measured a particle (because it does not yet know that it as moved) ?
There are no particles, an electron is a unit of electrostatic induction. The so called electrons on the outer shell of an atom are simply levels of the magnetic field. Valances are electrostatic levels (not electrons). Every atom is a toroidal electrostatic polar dynamo (magnet). The one dimensional view of the atom, is nothing more than the top view of the toroidal magnetic field.
You often hear that, in an EM wave, what is happening is that the wave propagates by 1) a changing electric field which produces a magnetic field, and 2) and changing magnetic field which, in turn, produces an electric field. And so on and so on. I can see how the changing electric field could produce the magnetic field, but it seems as if the magnetic field would be much too weak at 1/c proportional to re-create an electric field 300 million times stronger than it. How does that work?
Am I correct in understanding that it is actually impossible to detect the analogue instantaneous field strength variations of light due to it being quantized ?
well the oscillation of the E-field has a magnitude of 10 to the power of 14 Hz, if you calculate the frequency associated with speed of light. That is a very high frequency (fast). I'm not even sure if we have the means to measure discreetly frequency of that magnitude. i think even the highest frequency we can generate these days is in the order of gigahertz or terahertz, which is significantly lower than the frequency of light. of course that is the easy explanation. i'm sure theoretical physicists have a more complex and abstract formulation to answer your question, but unfortunately few people speak their language.
Both magnetic and electric component of EM-wave oscillate at same phase so the total energy of wave must oscillate between 0 and non-zero value. Is the energy stored/received in a way like heisenbergs uncertainty principle says that momentarily energy can be borrowd from time-space or is it wrong to think it like that? Imo it would sound interesting to think that even em-field has some sort of inertia to slow down the change of its value and energy of time-space is not absolute zero but floating
(Abstract Question) I assume if in retrospect between "observer" and/or "observation" there is 1/2 reality that is "absolute"? So can I logically conclude there is a 1/2 reality thats is "un-observed"?
In my previous posts, I forgot to add that during the last part of this video you explained how a radio wave propagates from an antenna. It is implied that a simple sine wave radiates outward. What might be helpful is to add a picture like the one in wikipedia. Google "antenna (radio) wikipedia" and at the wiki page "Antenna_(radio)", look at the second picture from the top. It shows EM waves for a dipole antenna.
When an em wave travels in free space free of charge or current densities, the electric and magnetic fields are in phase. Hence there comes a point when both electric field and magnetic fields become zero simultaneously. How does light propagate after this situation. Since both magnetic and electric fields are zero, how would they induce each other and propagate?
I didn't understand that field lines inside the sphere is smaller and outside the sphere is bigger, you join these lines and said it kinks and these kinks are producing light wave . Please ! Explain sir
So... w = e^2/2 + h^2/2, right? And we all know the law of energy conservation. And here is my little question: if density of energy is maximum on the top where does it go at point which accroses axis 'x'?!!
Re: final minute or two. So, you're telling us, then, that Ray Davies and his pals are responsible for light going as fast as it does? ;) (Sorry - I just _had_ to get this one in!)
Great video! Something I don't quite understand is isn't light carried by photons witch are particles? Or is this a view at light from the Maxwell equations? Feynman emphasized a lot in one of his lectures that light is very strictly a particle vega.org(dot)uk/video/subseries/8
Dang i wrote out most of the equations to help people & now my comment seems to have disappeared :( oh well. I'll redo it later Anyway the main thing is to memorise them all using flashcards & space repetition memory boosting software. That's still going very nicely.
I wonder if Maxwell wondered if because the speed of light is made up of constants, it must always be the same for all observers in all reference frames?
I don't think he did because he would've went further to relativity or maybe not. Can you equal maxwell with einstein? Lol if he did we would consider maxwell to be greater then newton in a way because he has acheived way to much.
TheoryofHobin Oh, I don't know about that. To do the math you have to have the math. Any efforts of Maxwell would have been futile without Newtons calculus. Really he probably wouldn't have had the time to create calculus too. Similarly Einstein would have been stuck without Rieman and his treatment of multidimensional analysis. I think Reiman's work came around in the 1850s. So the tool was in the box but just barely, for Maxwell. You really can't fault Maxwell for not taking another step after revolutionizing the study of physics. How many times did Niel Armstrong go to the moon? Why didn't he go to Mars shortly there after? We have the technology.
Probably not. In Maxwell's time they still thought that light was a wave in the ether. So it would have to move at a constant speed through the ether regardless of the speed of the observer.
Does any one over here really understand what divergence actually means in real life terms? More specifically, does anyone here comprehend this interpretation of Gauss law for magnetism and what B.S. this is?
No one in humanity knows why negative charge repels negative charge (i.e. why electrons diverge from each other, pushing each other away & outwards = divergence of greater than 0). So I think the answer to your question is no. The general consensus is that a wizard did it
@@alwaysdisputin9930 Maxwell's theory of electromagnetism and specifically, Insistence of of Hendrik Lorentz to use it in interpretation of standard model of atom doomed physics (in my humble opinion)
@@alwaysdisputin9930 I have finished electrotechnical school and I had basic physics as well. worth of mentioning more than 8 years researching physics , starting from tis modern interpretation and going back all the way to Newton and Galileo. For me answer is simple, Universe is fluidic.
@@websonic1000 Yes there's a bunch of reasons for thinking you are right: 1) Light is like ripples on a pond 2) Electricity has hydraulic equivalents 3) Spacetime seems to flow into mass - ScienceClic's video animates this - this is why if i let go of an apple it starts to accelerate to the floor 4) Black holes seem to have a river of spacetime flowing through them such that light can't overcome the current & escape 5) Breathing meditation makes the mind very calm & still like when turbulent water becomes calm 6) Dreams are very responsive to what the mind does - this reminds me of the way water is responsive 7) i heard mountain ranges have fluid properties It makes me want to study DrPhysicsA's videos on fluid dynamics
Force divergence is magnetism, longitudinal magnetic, reciprocating, space and time creating phenomena. Magnetic divergence along with vibration, manifests matter via the aether, magnetism creates our voluminous visible universe. Divergence is longitudinal, outward propagating magnetic field in this case. The dielectric (energy or electro-static) has a downward causation or transversal, the magnetic field has a longitudinal divergent, outward causation, which creates magnitude, volume and space in front of you.
Did u see David LaPoint theory of light? watch?v=lpI6ikj1G-s Its very interesting. It enplanes why light beds at the edge of thing, why the prism split light and double slit experiment.
as I learned in trigonometry and electronics = dynamic trigonometry is energy wave physics as seen on an oscilloscope also the only 2 concepts are r and t and 2 objects m and Q or (m/Q)*(r/t) = c*SQR(k/G) light just current change or mass charge (voltage) as inductive reactance leads +90 and capacitive reactance -90 lags xz current being cos or I (magnetism)being 90 out of phase and horizontal longitude yz voltage being sin Q and vertical latitude a double 90 phase shift in phase and polarization xy being a vacuum the photon leaving and pressure the photon coming azimuth
I studied physics in college, so let me share my take after wasting that money. Describing what you see it do with math is NOT an understanding. Your words do not include anything about WHY electricity and magnetism are perpendicular! That's pretty important, but myopic math followers don't know there's something missing. A cross product turns numbers perpendicular FOR NO PHYSICAL REASON. SO, at that point, YOU'VE LOST TOUCH WITH REALITY! You are all probably smarter than me, but you are not thinking for yourselves. You believe what you were taught. Even basic mechanics using angular momentum has become a math analogy that misses causality. Look at my later video. The "cause" is better than "what it does."

Your final analogy about 'how' electromagnetic waves are produced. Does it have an adjusted quantum mechanical picture ?
continued -- From that microwave photon link, a microwave photon has a lower power level than a visible-light photon, but what about size? Is a microwave photon bigger in size (volume) than a visible light photon? Is it the same shape (one is generated from the up/down on an antenna, the other from an energy drop)? Can you discuss optical antennas? I realize that this is a long list of questions, but I know you're looking for feedback. Again, thanks for producing your videos.
Here is a simple way of looking at it :
Curl of E = -dB/dt (negative sign is less relevant here)
As E exists solely in the x-direction,
Curl of E = dE/dz y (a y vector with a magnitude dE/dz)
Conclusion 1: B is in the y-direction.
Simply put, dE/dz = dB/dt
Now, we consolidate the fact that differential equations of E and B are w.r.t different variables dz and dt.
Since dB/dt = dB/dz · dz/dt,
dE/dz = dB/dz · dz/dt
dE/dz = dB/dz · c
Conclusion: rate of change of E wrt to z is identical to that of B.
Since E wrt to z is sinusoidal, wave B is sinusoidal and entirely in phase with wave E. In addition, E is larger in magnitude by a multiple of c.
Another worthwhile video, good job. I'm looking forward to the whole series on light. At some point, could you discuss what is, and is not, known about the link between an electromagnetic wave and photons? Can you draw a picture of a photon (is it a "wave packet", burst, something else)? I can't post a link, but if you Google "Breakthrough for photons in the microwave frequency range", it discusses the generation and detection of microwave photons. Can you explain what they are doing?
A photon is just a made up term by quantum physicists or bean counters. A photon is a scalar pulse (longitudinal wave), a dielectric pulse or condensate, like a burst of energy where the transverse dielectric and the longitudinal magnetic intersect. There is no such thing as a photon. Electrons on the outer shell of an atom are simply a measure of magnetism or level of magnetism. An electron is one unit of dielectric induction. An atom is an electro-static dynamo.
If the electron can oscillate continuosly and generate a continuos wave? Energy is transmitted in packet (photon). How many electron oscillation needs to generate a photon? When a photon is generated then the electron stops? Who make it restart? (The same principle also apply to black body radiation?)
Rosario Leonardi . A beautiful attack on the idea of a photon. Or on the classical wave. When will humans resolve this?
There's no such thing as photon, it's simply a fabrication by quantum physicists. A photon as commonly known is a scalar pulse, a dielectric or electro-static pulse (longitudinal dielectric condensate). I do not use the word photons, they are not particles, can you shake the photons out of your photographic equipment?
At 2:25, where you showed the cross product or curl of the vector, was that the determinant you took to get that expression? If so, isn't the second expression supposed to be negative? I.e., x-hat minus y-hat plus z-hat?
Brilliant explanation.
Thank you... could you please demonstrate how to change the integral to diferencial form?
Hi Doc, are you saying that light is the discrepancy between 2 frames of reference: the one that measures a particle(ex electron) and the one that has not measured a particle (because it does not yet know that it as moved) ?
There are no particles, an electron is a unit of electrostatic induction. The so called electrons on the outer shell of an atom are simply levels of the magnetic field. Valances are electrostatic levels (not electrons). Every atom is a toroidal electrostatic polar dynamo (magnet). The one dimensional view of the atom, is nothing more than the top view of the toroidal magnetic field.
Your drawing at 30:00... that's impressive!
I can never get my perpenduicular B field to look right!
Draw them at a slight angle and you'll get it right. I'm bad at drawing but through practice I've got a handle on it.
thank you so much.
you are really a good teacher..
You often hear that, in an EM wave, what is happening is that the wave propagates by 1) a changing electric field which produces a magnetic field, and 2) and changing magnetic field which, in turn, produces an electric field. And so on and so on. I can see how the changing electric field could produce the magnetic field, but it seems as if the magnetic field would be much too weak at 1/c proportional to re-create an electric field 300 million times stronger than it. How does that work?
Am I correct in understanding that it is actually impossible to detect the analogue instantaneous field strength variations of light due to it being quantized ?
well the oscillation of the E-field has a magnitude of 10 to the power of 14 Hz, if you calculate the frequency associated with speed of light. That is a very high frequency (fast). I'm not even sure if we have the means to measure discreetly frequency of that magnitude. i think even the highest frequency we can generate these days is in the order of gigahertz or terahertz, which is significantly lower than the frequency of light.
of course that is the easy explanation. i'm sure theoretical physicists have a more complex and abstract formulation to answer your question, but unfortunately few people speak their language.
Both magnetic and electric component of EM-wave oscillate at same phase so the total energy of wave must oscillate between 0 and non-zero value. Is the energy stored/received in a way like heisenbergs uncertainty principle says that momentarily energy can be borrowd from time-space or is it wrong to think it like that? Imo it would sound interesting to think that even em-field has some sort of inertia to slow down the change of its value and energy of time-space is not absolute zero but floating
(Abstract Question)
I assume if in retrospect between "observer" and/or "observation" there is 1/2 reality that is "absolute"?
So can I logically conclude there is a 1/2 reality thats is "un-observed"?
In my previous posts, I forgot to add that during the last part of this video you explained how a radio wave propagates from an antenna. It is implied that a simple sine wave radiates outward. What might be helpful is to add a picture like the one in wikipedia. Google "antenna (radio) wikipedia" and at the wiki page "Antenna_(radio)", look at the second picture from the top. It shows EM waves for a dipole antenna.
When an em wave travels in free space free of charge or current densities, the electric and magnetic fields are in phase. Hence there comes a point when both electric field and magnetic fields become zero simultaneously. How does light propagate after this situation. Since both magnetic and electric fields are zero, how would they induce each other and propagate?
How could E/B=c at all points? For example, at the nodes, E=0 and B=0, which would imply c=0?
Fantastic video!
About the cross product, can I use the matrix method instead of the differential method? Thanks.
I didn't understand that field lines inside the sphere is smaller and outside the sphere is bigger, you join these lines and said it kinks and these kinks are producing light wave . Please ! Explain sir
do you have a pdf or word version of your lectures Doc?
Any chance you have a formula sheet with all of this?
do you have a video about eddy current?
What does d/dt mean? I don't understand what it means or how it works
Thank you !! This is beautiful !!
Thank you for this beautiful explanation!!!!
The basic concept is photons at certain vectors turn into carbon atoms.
A wonderful video, thank you :)
So... w = e^2/2 + h^2/2, right? And we all know the law of energy conservation. And here is my little question: if density of energy is maximum on the top where does it go at point which accroses axis 'x'?!!
Thank you so much!!!
@0:25 Pretty cool
That's Awsome!
THANK GOD FOR THIS!!!!!
great
Re: final minute or two.
So, you're telling us, then, that Ray Davies and his pals are responsible for light going as fast as it does? ;)
(Sorry - I just _had_ to get this one in!)
No, they're responsible for the people who sway back and forth.
Great video! Something I don't quite understand is isn't light carried by photons witch are particles? Or is this a view at light from the Maxwell equations? Feynman emphasized a lot in one of his lectures that light is very strictly a particle vega.org(dot)uk/video/subseries/8
Hi. In this lecture you mention a video on wave functions. Could you direct me to it?
ruclips.net/video/R4KdZ93BrZM/видео.html
thank you.
Can anyone provide the link for the explanation of why:
psi = sin(kx-wt)
psi = e^i(kx-wt)
how this is derived ?
thats pretty much an identity…
Dang i wrote out most of the equations to help people & now my comment seems to have disappeared :( oh well. I'll redo it later
Anyway the main thing is to memorise them all using flashcards & space repetition memory boosting software. That's still going very nicely.
1:08 They call it Divergent.
I wonder if Maxwell wondered if because the speed of light is made up of constants, it must always be the same for all observers in all reference frames?
question or statement?
TheoryofHobin both.
I don't think he did because he would've went further to relativity or maybe not. Can you equal maxwell with einstein? Lol if he did we would consider maxwell to be greater then newton in a way because he has acheived way to much.
TheoryofHobin
Oh, I don't know about that. To do the math you have to have the math.
Any efforts of Maxwell would have been futile without Newtons calculus.
Really he probably wouldn't have had the time to create calculus too.
Similarly Einstein would have been stuck without Rieman and his treatment of multidimensional analysis. I think Reiman's work came around in the 1850s. So the tool was in the box but just barely, for Maxwell. You really can't fault Maxwell for not taking another step after revolutionizing the study of physics. How many times did Niel Armstrong go to the moon? Why didn't he go to Mars shortly there after? We have the technology.
Probably not. In Maxwell's time they still thought that light was a wave in the ether. So it would have to move at a constant speed through the ether regardless of the speed of the observer.
That's just the standard form of the cross product.
wow tanks alot!!!!
last 5 minutes = mind blown
divergence and contravarium are awfully same
Does any one over here really understand what divergence actually means in real life terms?
More specifically, does anyone here comprehend this interpretation of Gauss law for magnetism and what B.S. this is?
No one in humanity knows why negative charge repels negative charge (i.e. why electrons diverge from each other, pushing each other away & outwards = divergence of greater than 0). So I think the answer to your question is no. The general consensus is that a wizard did it
@@alwaysdisputin9930 Maxwell's theory of electromagnetism and specifically, Insistence of of Hendrik Lorentz to use it in interpretation of standard model of atom doomed physics (in my humble opinion)
@@alwaysdisputin9930 I have finished electrotechnical school and I had basic physics as well. worth of mentioning more than 8 years researching physics , starting from tis modern interpretation and going back all the way to Newton and Galileo.
For me answer is simple, Universe is fluidic.
@@websonic1000 Yes there's a bunch of reasons for thinking you are right:
1) Light is like ripples on a pond
2) Electricity has hydraulic equivalents
3) Spacetime seems to flow into mass - ScienceClic's video animates this - this is why if i let go of an apple it starts to accelerate
to the floor
4) Black holes seem to have a river of spacetime flowing through them such that light can't overcome the current & escape
5) Breathing meditation makes the mind very calm & still like when turbulent water becomes calm
6) Dreams are very responsive to what the mind does - this reminds me of the way water is responsive
7) i heard mountain ranges have fluid properties
It makes me want to study DrPhysicsA's videos on fluid dynamics
Force divergence is magnetism, longitudinal magnetic, reciprocating, space and time creating phenomena. Magnetic divergence along with vibration, manifests matter via the aether, magnetism creates our voluminous visible universe. Divergence is longitudinal, outward propagating magnetic field in this case. The dielectric (energy or electro-static) has a downward causation or transversal, the magnetic field has a longitudinal divergent, outward causation, which creates magnitude, volume and space in front of you.
Did u see David LaPoint theory of light? watch?v=lpI6ikj1G-s
Its very interesting. It enplanes why light beds at the edge of thing, why the prism split light and double slit experiment.
as I learned in trigonometry and electronics = dynamic trigonometry is energy wave physics as seen on an oscilloscope
also the only 2 concepts are r and t and 2 objects m and Q or (m/Q)*(r/t) = c*SQR(k/G)
light just current change or mass charge (voltage)
as inductive reactance leads +90 and capacitive reactance -90 lags
xz current being cos or I (magnetism)being 90 out of phase and horizontal longitude
yz voltage being sin Q and vertical latitude
a double 90 phase shift in phase and polarization
xy being a vacuum the photon leaving and pressure the photon coming azimuth
I studied physics in college, so let me share my take after wasting that money. Describing what you see it do with math is NOT an understanding. Your words do not include anything about WHY electricity and magnetism are perpendicular! That's pretty important, but myopic math followers don't know there's something missing. A cross product turns numbers perpendicular FOR NO PHYSICAL REASON. SO, at that point, YOU'VE LOST TOUCH WITH REALITY! You are all probably smarter than me, but you are not thinking for yourselves. You believe what you were taught. Even basic mechanics using angular momentum has become a math analogy that misses causality. Look at my later video. The "cause" is better than "what it does."

Ah...So, the universe conveniently accommodates the math geniuses by going about its business in a manner prescribed by their fancy math?
Unfortunately, your video never lives up to its title..."what is Light"...a real, physical phenomenon.
