Entanglement got left out in the rush to (not even close) explain Radio transmission and reception. Loop Quantum Operator Logic Fields Modulation Mechanism and here-now-forever => Singularity of current attempts at Inflation and Gravity wave-packaging formation are much closer to Actuality of Superspin Supersymmetry positioning and temporal transverse trancendental logarithmic time-timing sync-duration identification.
Does anyone Scientific want to keep this secret still, and if so, why?

Hertz, had he not gotten sick, might have RE-invented wireless telegraphy, but could not have been THE inventor, since Mahlon Loomis had already demonstrated it decades earlier, without ANY knowledge of Hertzian waves. It turns out not to require an AC (let alone r. f) source feeding the spark gap, because DC power (as supplied by kite and ground, Franklin style) creates r. f. transients when a long wire is switched into and out of contact with such a source.

I got a charge (pun intended) when you explained that radio was NOT music. Most people have a very narrow idea of what radio is: broadcast AM or FM. I had someone brag that he didn't listen to the radio anymore. All the while he was playing Spotify over a Bluetooth speaker. I didn't bother to explain to him that a Bluetooth speaker was very much a type of radio receiver, so he WAS in fact listening to the radio! LOL.

Thank you for putting these videos in plain terms. Growing up we rarely had practical explanations in school to stimulate our interest.
Your videos remind me of another series called, The Secret Life of Machines. A couple of English guys explain the history of home and office technology.
Thank you for all your time and effort that you've invested for the benefit of the public.

You stated that he proved that visible light is electromagnetic waves. But you didn't give any such proof in the video. He proved that he could create electromagnetic waves that are different than (visible) light and therefore they exist. But how does that prove that light is also electromagnetic waves?

Maxwell, though known as a theoretician, as performed some amazing experiments. Had Maxwell lived longer, and not die in his 50s, he may have had the 1st experiments demonstrating radio.
As for Hertz, it was still cycles per second until the 1960s, when the hertz was adopted.

My apologies to Heinrich. While I knew about the discovery being his I have resisted Khz, and Mhz. From my earliest days they were kilocycles and megacycles. I guess he really does deserve the recognition. I still believe in micromicrofarads instead of picofarads. LOL

Thank you so much for your fascinating videos.
Perhaps I have missed it, but you don't seem to have mentioned Bardeen, Shockley and Brattain who won the 1956 Physics Nobel Prize for what I consider the greatest invention of the 20th century - the transistor.

I'm impressed.
I'm a fellow-citizen of Guglielmo Marconi, fanatic admirer of him.
I'ts very impressive to hear here that if Hertz had lived more years, he probabily would have invented radio-telegrapy!
Impressive indeed!

Beautiful! I'm an Amateur Radio operator and am so glad that they renamed the unit of frequency measurement after Mr. Hertz. so instead of megacycles, we use megahertz! A lot of the old hams still say MC's instead of MHz!

Correction: At the end of the video I mention that Tesla went to Paris for the World's Fair 5 years after Hertz died. He actually went 5 years before Hertz died. Sorry, I blame my small children for all of my mistakes: )

On a sad historical note, Nazi Germany removed anything which honored Hertz becasd he was Jew. Moreover, the Nazi renamed the unit of one cycle per second to helmholtz; but the symbol remained the same, Hz.

Madam it will be nice to have your bio somewhere, number if children, the college you went to, your degree, how you are so knowledgeable in so many facets of physics and other subjects

Thanks for the stories behind the physics. Especially for this episode, as I sometimes refer to Hertz as my neighbor, as I lived in the house right next to his home in Bonn for five years.

Kathy, these videos are great but you really need to work on your spelling. I think Ive seen you misspell Marconis name three different ways already. Its Guglielmo Marconi.

Reminds me of the time when I was a young boy growing up in Woonsocket RI, when on a dare, I stuck my tongue in an electrical socket. OUTCH! Like Hertz I was suddenly inspired.

Sometimes a person buys a house that was previously a meth lab. Often the house has to be torn down. If you're going to buy a house you could talk to the neighbours first.

Even though it's not the focus of the video, I think Kathy's explanation of how a vinyl record works is VERY good. Very simple and concise while being completely accurate.

Radio waves were discovered in 1879 (9 years before Hertz) by the Welsh-US inventor David Edward Hughes. It was demonstrated to the Royal Society in London in 1880.
