What is missed by everyone is the fact that space, "as Gauss stated, is not observable." It is the Electric Field that humans see and observe. The information which is transmitted to an observer through time is in the Coriolus component of the Electric Field ( has been referred to as the magnetic field). That information observed by humans is from the past.

When you gave the example of the Sun for visible light, I thought that maybe it would have been good to add that the Sun isn't limited to visible light. Thanks.

[@robertdiggins7578]

Can waves propagate through no medium? Have you contemplated the existence of a medium in "free space"? Could a test, better than P&W, be devised to double check with more rigor? When you shield an antenna from the microwaves coming from the Earth's oceans, according to data from the Herouni Antennae, you do not measure any Cosmic Microwavve Background. Why don't we try that and why didn't we think about doing that before? Also, when light slows down through a medium, such as glass, how does it speed back up to C after it passes through the glass? Doesn't C actually fluctuate, except that it's tied to the meter, making the meter fluctuate? Thanks!

[@charlesperry7300]

Excellent teaching! It is easier to follow the idea when the professor writes his flow of thought on the blackboard. The "front" blackboard is so innovative.

[@ElPasoTubeAmps]

I think your lecture is wonderful. I understood this as a child (I am now 72) as I was coached by my uncle, a chemist at ORNL, but have found few people that can comprehend or care about such things. But we love what we love. I would like to just randomly add that heating the concrete you mentioned around 1:15:00 is something I did a few years ago with a carbon arc. I think it was arcing at about 36V @ 70A. It ended up being a bad idea as apparently the water vapor in the concrete caused the hot-spot to explode (after becoming red hot) and blow very hot pieces of concrete all around and into my face. I was not injured seriously but it taught me a lesson that extreme temperatures (or anything else) can do unexpected things. Lastly, even after all these years, I still enjoy a good presentation like you posted here. I know it has been seven years since you posted but please keep up the good work and enjoy life. I know it would be subjective but it would be interesting to plot real-time ageing years with perceived ageing years as we grow older.

His demonstration of current going up and down in waves as it changes polarity, causing magnetic waves to be generated at right angles to that (perpendicular to the electric charge) is brilliant.

_" That's mainly because bad teachers. "_ yeah I tried Open University & it just wasn't that great an explanation so i gave up. Before that I tried a book called Engineering Mathematics by Stroud. It was awesome & so easy even degree level stuff. Another great teacher on KZbin is DrPhysicsA

[@lakshaygupta9061]

I've never seen a better explanation of em waves, atleast in high school

[@TabsZaMuchiri]

I randomly found this lecture. It's not related to anything I do but I understand it. The professor made it so simple to understand

[@michaelmarzano2759]

Professor Matt Anderson is AMAZING!!! So easy to follow compared to other physicists I’ve met.Keep up the great work Professor. Electro Magnetism has never been so well explained in my experience.

[@yoprofmatt]

Wow, thanks! Glad you're enjoying the videos. Cheers, Dr. A

[@ruwanthinayomi3502]

this's a awesome lecture i ever heard...thank uuuu

[@user-di1ce7cu6x]

It's amazing to watch him write and draw on that light board. He draws in "first person" while facing the viewer :)

[@tachikomah4203]

oh i've watched this 3 times by now after all these years, this is still the golden video for EM waves intro in 2022

[@yoprofmatt]

Wow, thanks much. Cheers, Dr. A

[@arkapaul42]

It really helped me for my exam!! Hope you will release a series about Astrophysics 😀😀

[@danielboone1570]

I love this. The way he explains and teaches these concepts and theories. Has made it very easy to understand and digest and also how to understand the way these examples works in the real world.

[@yoprofmatt]

I appreciate that. Certainly the goal. Sometimes it works. Cheers, Dr. A

[@romzcollainimz8533]

thank you for making physics seem so simple. I was taught physics some 30 yrs ago where the teaching aids were just a simple chalk and a board.. usually black, and of course half the time you're just looking at the teacher's back.. and if she was a beautiful curvaceous teacher, young testosterone filled young minds like mine was back then, your never really paid much attention to the board .. really.. so thank you for your beautiful explanation and your smart learning glass style teaching..

[@vijayshankar9529]

This is a great lecture , arguably the best on youtube

[@slightestimpression]

Ahhhhh i keep wiping my screen where his missing bits! other than that a great vid, nothing better than neo himself explaining parts of the matrix, Thank you MR ANDERSON.

[@JustAKomiFan]

I did also fall asleep and woke up to this, but you have such a nice voice and this is really interesting with how you explain and visualize everything

[@forfunonly4343]

Thank you alot professor. Cannot thank you enough being honest. Really appreciate, plus the fact this gold lectures are free. May god bless you!

[@zhara-lunethcarithuo275]

This is awesome! I'm so glad I found your channel. I really love physics, but unfortunately HS doesn't offer anywhere near as much detail as I like. I plan to major in software engineering for practical reasons in getting a job. However, I plan to try to get a master's in physics when I'm older, after making enough of a living beforehand.

[@scotfaber7926]

This seems a simpler than the heat-light-sound physics I had in college. It's still fun and informative. I am nearing retirement age and I keep toying with the idea of going back to school for a PhD in astronomy (which would mean an in-depth review of physics and algebra and trig and calculus and diff-EQ, etc etc etc). It's big commitment but it's not as if I would be in any hurry.

Great Job Prof.You are helping us understand our universe better and giving us the power we need.Thanks

[@nedarezaie5950]

A fantastic Lecture. He describes all hard subjects in a pretty beautiful way.

[@acerovalderas]

Excellent explanations. Very clear presentation. Perfect speed for beginner students.

[@felipegalvezcarrasco7834]

Really thanks a lot, an amazing class, I´d like you to activate the subtitles in this video to help people who speak in other languages, I can help with Spanish. Greetings from Chile.

[@faizahmadcheema3197]

Physics is a pure field of science and dear sir U teach this subject with so much enthusiasm and clarity that even dunces can understand it very easily .U R really a blessing of the lord of Universe

[@curiousgkc2879]

Such a simple and flawless explanation with every minute detail. Loved it. Thank you, ♥sir Anderson...your lecture makes us curious to know everything in detail.

[@yoprofmatt]

You are very welcome. Keep questioning (including what I tell you). Cheers, Dr. A

[@nomasan]

His reaction to a phone call is .. nice My teachers would destroy the phone and send the student to the principal

[@mushtaqbhat1895]

My current favorite lecturer is Robert Sapolsky _ an altogether different subject but somewhat similar delivery. A relatively thorough grasp of the subject in times, when the rapid changes and developments and occasional paradigm shifts in all fields of science make it all the more difficult to keep abreast of the changes taking place in any given discipline. A constant focus upon the audience; which transforms an otherwise dry prose into a narrative or even on occasion into a kind of conversation that inevitably infects the attentive listener. The charismatic Feynman was undoubtedly very gifted at this; he probably infected almost everyone in his classes with love for the subject he so loved to talk about. It all is unfortunately not to acquired or trained. In certain way it is also perhaps person dependent. Nevertheless, I assume training can also help. Intonation, regular breathing, voice, the quality of sound, the command of language and correct pronunciation and especially the well paced delivery; where you pause at the right moment for right amount of time for the neural networks to prepare for a new inputs and equally important the inclusion of a short summary of the proceeding subtopic at the end. I wonder if you also do some kind of Meditation or Yoga; just curious? And last but not least a fully well planned out structure that seems to give the illusion of a perfect transition from a subtopic to another subtopic; so that the listener is almost unaware of the effort that the lecturer may have made to make it possible. It seems almost natural, effortless and so obvious. But I assume it is anything but that. It hides the work involved in such easy paced flowing lectures; which assume are also the result of many experiences that contribute toward such clarity of structure and presentation. I am sure your lectures will inspire and help aspiring students and spread this increasingly important subject for mankind and its global citizens. Not only is it important for understanding the real world outside but will become more and more important in the world that we are creating and superimposing on the one that created us _ our inescapable new reality; which may not necessarily be the same as our ancestors perceived it and this world has a lot _ for good or bad _ to do with Physics, Chemistry and Mathematics. Even more important for mankind; these subjects also help in understanding human behavior _ which involve elector-chemical signals, hormonal chemistry and energy transfers. Such knowledge; even when it may not turn out to be the basis or the ultimate essence of reality, will no doubt remain an essential tool for all future investigations about the world and cosmos we live in; besides of course getting some lucky ones big social acclaims like Prestigious Prizes, or Fame or Money and for great many a fulfilling profession and for people like me; a truly effortless insight into the nature of the physical world; that I live in and interact with daily. Thank you!

[@maryannking5491]

Sapolsky is awesome and so is Noam Chomsky. Richard Dawkins, Klaus, Greene and a few others are also great.

[@poisonouscarnage2289]

I was cleaning up round the house while listening and I saw the light refracting trough the glass door forming a rainbow and I realised I was seeing a Fourier transform right in-front of my eyes, it’s funny because I already understood and knew about these concepts individually but hearing it put like this together has blown my mind how all of these things are the same thing.

[@curious8321]

If I had a physics teacher like you in school, I wouldn't have left science after school..... Thanks for sharing this video.

[@yoprofmatt]

Then come on back! It's never too late. Cheers, Dr. A

[@user-ij5yu5ir8v]

Waht a course professor Matt Anderson, thank you.

[@yukchow4821]

Thank you for the great lectures on the electromagnetic wave. l particularly enjoyed the section on the antenna. Any recommendations on books for this subject?

[@mernaeshak7029]

I've never seen something beautiful like this in life

[@magnustorque5528]

This guy is really lucid and he is very skilled at presenting those illustrations. You can see that this isn't the first time that he has rendered those illustrations on that transparent surface. Not as easy as it looks.

[@ericzarahn9343]

Regarding the diagram at the beginning of the lecture: wouldn't the magnitude of the electric field at the midpoint get larger as the two oppositely charged point-masses move closer to one another? My reasoning is based on the 1/r in the electric field formula and superposition. As the charges move towards each other, the r term gets smaller. (edit): I was assuming that the E-field being plotted was that at the midpoint of the point-masses. Is that correct?

[@MrYaatri]

E filed of a single charge would get larger as we get closer to what is the midpoint of two oppositely charged point charges, if there were a single charge. But we have two charges. When the two charges overlap, are at the same point, the net charge is 0. So Dr Anderson is right since, no (zero) charge produces zero field. If you think of a point charge as a very small sphere of uniformly distributed charge, even then l, by Guass's law, the field produced at the center would be zero. As we approach the center, the distance from the center varies linearly. The 1 over r quare term in the field varies as 1 over r square but the enclosed charge varies is 1 over r cube. So the field falls linearly as r.

[@charanreddynallapareddy5418]

Very true! In fact, I too was thinking about that. He's right when he's saying that those oscillating charges produce oscillating electric field but not because of the reason he's saying. It is because of the acceleration of particles themselves. In SHM, the particle's acceleration is proportional to the displacement from the mean position. This implies that acceleration is zero at the mean position and highest at the extremes. Now, since the electric field is directly proportional to this acceleration, we see the electric field also following this "displacement analogy". The farther the particles, the higher is the acceleration and the higher is the electric field and vice versa. Hope this clears your confusion.

[@sameerdatta7287]

Was thinking the same but@@MrYaatri cleared the doubt.. Thanks man

[@pradipkundu3149]

Did you upload the lectures of upper level physics that you mentioned . just curious. I love your videos by the way. Cheers!

[@thedouglasw.lippchannel5546]

This course presentation is just what I need.

[@fabblo5588]

I often feel sleepy while my teacher explains some math or physics calculation. And I used to play this channel's videos at night, love it🖒.

[@yoprofmatt]

Ah yes, my specialty: putting my students to sleep. Cheers, Dr. A

[@joshliaw]

From the cover, you can tell this guy looks like the kind of person that knows what he's talking about~
