but all of you would like to understand.
this video watches like an action movie.

I was challenged with introducing all of electromagnetics in one hour to students just out of high school and entering college. 
This video is my attempt at this.  Electromagnetics is a very mathematically intense discipline involving vector calculus,
differential equations and other things that make this challenging.
Here I have tried to explain everything visually with no math. 
I do present some equations, but only to satisfy students curiosity about what the equations may look like. 
I hope you enjoy the video and get something out of it. 
I also hope it helps recruit more students into the area of electromagnetics and optics. 
The video was fun to create!

I didn't finish all of the explanation started at:
There are two topics worth  your attention:

I just stopped for a while and I will continue it in the free time.
Believing is not is a lot of work to keep the content clear and understandable for both the experienced and not experienced
reader, especially in two languages English and Russian.

Controversial ownership rights to hero symbol of Nicola Tesla between
Croatia and  Serbia keeps him alive
_{in  their  research , science  and history.
Group of scientists from Serbia/Croatia is publishing  plenty  papers about Tesla life, work and scientific contribution,including  experiments, analysis  calculations sponsored by  Government
Most of these papers is available to everyone but you need sign free membership or just only give "them" your email. like:  https://www.academia.edu , ieeexplore.ieee.org, /www.researchgate.net,
so again : give  "them"  your  email - nothing more   is needed.}
Please google :
scientists name or  article  of interest. :
Poljak, Dragan; Blažević, Zoran; Šesnić, Silvestar; Cvetković, Mario
or
Name of article:
Full wave model versus transmission line representation of Tesla's wave propagation:
155th anniversary of birth of Nikola Tesla
_{They will send you articles for free based on your search- others can't find on line.
few tips after  you done with registration: If you use e.g firefox , You'll see the paper, you want to download it,
they may ask you for  membership but  when you close the paper you'll see that it  automatically downloaded it.}
This particular  paper talks  about Tesla's transmission energy over Earth.
_{So it was not Dr James Corum, nor  Sommerfeld-Goubau or Zenneck but Tesla who was first.
Information matches exactly to Surface Wave  known as Zenneck Wave in the  Earth Air Interface.
Historically  Tesla Tower was demolished  due to JP Morgan, Marconi lost in Bolinas California  due to RCA,
Dr James Corum gave up in Texas and Viziv went chapter 11.}

quotes:
Tesla's propagation concept of wireless transmission of energy//
Telsa's ideas on non-Hertzian waves*(1899)//currents, voltages and radiated fields//transmitted power via Tesla's propagation path through the Earth  //
//Energy of such a system, according to Tesla, is not radiated, but rather conserved in a Tesla's transmitter -Earth system from which it may be absorbed by means of properly adjusted receiving antennas, as shown in Fig. 2 //

the path-loss increases with frequency due to a finite conductivity of the Earth, it follows that the use of lower frequencies (less than 20 kHz [14], [25]) for power transmission is required. Tesla perceived this system during the Colorado Springs experiments [16].//

_{Note it may be  confusing how Tesla envisioned it but  picture  clearly shows  wave traveling around the earth left right, in the interface  Earth Air.}
