How Heinrich Hertz Discovered Radio to Validate Maxwell's Equations

How did Hertz discover radio waves & what does that have to do with Maxwell's equations? Watch this video and find out!

Thanks to Kim Nalley for the lovely music

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 :)

Up until now, I thought that Hertz was weirdly inept or lazy. He discovered radio waves and didn't think of the radio, he discovered the photoelectric effect and didn't follow up like Lenard did. Why? Oh, he died tragically young.

Thanks Kathy, I would not have looked up his life and learned more about him if it hadn't been for you. I now have much more respect for Hertz.

If only the History Channel were the way they used to be instead of making programs about extraterrestrial aliens, they would do what you are doing. Keep up the good work.

You are a wealth of information. It's a pleasure watching you explain things. Thank you!

Thanks for all these history episodes about electricity, they are so interesting and entertaining! M.S.E.E Widmark

The analogy to a vinyl record helped me understand radio waves. I definitely was confusing them with sound waves. Thank you!

Kathy, I have officially fallen into the rabbit hole of your videos. Thank you for making these.

These kinds of inventors have been my heroes since my childhood.

It's really interesting to see how this story extends between figures you normally don't even think about together (from Heinrich to Tesla). I'm enjoying these videos.

[Robinzano]

The way you explain physics is fantastic. I can (and do) watch your videos all day long.

I love your channel! Learning about the OG's in electricity is sooo fascinating.Hertz's "Electromagnetic waves were of no use whatsoever" must be the mother of all understatement.

[edumation]

Although I teach electromagnetics and I have been involved with this field for 30 years, your explanation is attractive and must be very useful to learners. I always like to listen to others explaining this immortal topic!

[dalsenov]

Very informative! Many thanks! I don't know exactly what's more beautiful: the science or the history of science!

Kathy -
An excellent detailed report.
Thanks!

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.

[gwernette]

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.

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!

[jamesslick]

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.

This channel was one among I was searching For..
I really loved the content chosen..
The way of presentaion..
Combining History and Physics..

And Thank you 😍😍

[aidabug]

Thank you for making this video. I have been looking all over the internet for info on electromagnetic waves.
