I wish I had such a teacher like him when I was young...He is so passionate to teach! He deserves much more viewers! I refer him all the time to ever want to understand science.
I am enlightened... I became so focused at one point, and lost myself so much in the joy of finally getting what this all meant, that I literally forgot my own existence for a while. You're the ONLY one Mr. Gibson. And you will never be forgotten. Thank you so so so very much.
Bow down to you sir. I am not a math guy. I was an average student in my school. The way you teach me. courage to learn again. Thank you so so so so so so much for your effort.
I've never seen such a science related lecture which is incredibly comprehensive like this in less than an hour. How can you integrate the simplest physics and the most advanced/complicated ones into one lecture? How can you REASONABLY link them to make it super understandable to average persons. Amazing! I wish there are more lecturer, teacher, tutor, professor, or whatever terms, like Jason Gibson in the world. Thank you and RU-vid!
Thanks a lots sir for reeducating us ...i dont fully understand these things during my college time ..but still i graduated with a half cooked knowledge
so the relation between electric and magnetic fields is what creates the electricity in a generator right? Basically we spin magnets around a wire to do it. The spinning happens from the steam, from the heat, from the energy of broken bonds in the fuel
This is an EXCELLENT comment. The short answer is the magnetic field lines will always form a closed loop. But the wave I drew is a "plane wave" which means it is very far from the source (antenna) or the moving charges that are causing that wave. If the wave has propagated very far from the source, then the radius of curvature of the closed loop on the magnetic field is so large that the loops are infinitely large. So the answer is, for example, starlight coming from across the galaxy and hitting us consists of electric and magnetic oscillating fields. Those magnetic fields DO form closed loops, but the loop is so large that it approaches infinity and it looks like I drew them in the diagram. Here is a link with a good thread on this: physics.stackexchange.com/questions/562473/magnetic-field-closed-loop-lines-in-an-electromagnetic-wave
51:55 the sine waves resembles DNA. Given that DNA has some electric properties associated with it, do you think there's a correlation with the fact it resembles two sine waves out of phase with each other? Or is it coincidental?
Egy kis fázis problémát látok a két szembemenő hullámnál. Ha szembemennek, akkor a pozitív félperiódus először a negatívval találkozik, tehát nem fogják egymást erősíteni. Ellen-fázisú interferencia. Az elektromágnesen hullámoknál, szintén fázis probléma van. 90°-os nak kell lennie a mágnese és az elektromos térerőnél (E-H), hogy terjedő hullám legye. Mechanikai analógia, a hinta, ha mozgásban van, nem lehet a mozgási energia és a helyzeti energia egyszerre zérus, még egy pillanatra sem. Az egyik energia alakul át a másikba. Így lesz hullám.

In Calc 3 we did the math for Maxwells Equations, and the professor said don't worry about what they mean. You will find out in your engineering courses. I don't remember even talking about them in physics, and in my EMF class my professor said you should already know these, and the test is on Friday. So yeah, I just memorized them, did the math and got my grade for the course. It wasn't until videos like these where I actually understood what they meant. Embarrassing, but true.
@@MathAndScience It would be awesome if you did a series in EE. Signals, Controls, EMF, Power systems etc. I would pay for them from you for sure. I don't pay for anything, but I would pay no doubt.
Yes, I fully agree Sir Jason is a God sent , gifted with an immense talent to bring his knowledge to the layman where EDUCATION was unknown to quantify .Thank you Sir , I can say that Maxwell Equation is hard to understand and you did convince me about the Calculus side of Partial Derivative. Now , I am clear and got what the four equations mean in electricity and magnetism theory. Again , beautiful video and we'll continue to follow more tutorials in Maths and Science Course
Love the free educational videos u make but I see the way u gulp after u talk for long and ur expressions say ur throat is very dry so I can advice u to have a bottle water around u 😌 remember to stay hydrated

Hi there Jason. I haven't watched this yet but and interesting point on the Maxwell equations is that no-one actually uses Maxwell's equations in their original form (20 of them). It was Oliver Heaviside who simplified them down to four using his own mathematical methods (Heaviside invented vector calculus and of course the H-step function [Heaviside Step Function]) to simplify them down to the four that are used today. Heaviside predicted the E3 layer (the Kennelly-Heaviside layer [see song in the musical Cats - Journey to the Heaviside layer]). The Telegraph Equations are also Heavisides derivation. At best, the equations are the Maxwell-Heaviside Equations. You guys should check Oliver Heaviside out. Interesting guy and there's nothing like the historicity of first principles. en.wikipedia.org/wiki/Oliver_Heaviside
@@MathAndScience Hi Jason. I would have loved to have has a few beers with Heaviside. Maybe you could include a mention of this amazing man in one of your presentations as what we commonly use which we don't attribute to Heaviside can be traced back to this amazing self-taught engineer. Maybe your colleagues and associates will be surprised to find that they have been using the Heaviside Equations all this time and didn't even know it. Just a thought. Oh, and keep up the great work - you're one helluva tutor. Where were you when I did my Engineering Math???? Not in the UK alas. Oh the wonders of the web!
