I like your content

Why do you play music while you are talking? Do you find the content boring?

Didn't know how much i needed this as an adhd female physics student with a very non lineair career and life path. Seems like our stumbling isn't only our weakness, but also our strength is the reassurence i needed. You are such a delight and so brave!!!!

Lord Kelvin's name was William Thomson not Thompson.

So sad what the happened to him! I found a old zenith radio with a oval yellow sticker on the back that says "FM the Armstrong system licensed under Armstrong patents" a model S-17366 ..interesting history!

Thanks Kathy. I wonder the degree to which Heaviside's misapprehending the quaternion significance of the 'twirl' dimension has maybe contributed to a century and a half of 3-dimensional bias and materialist cognitive imprisonment? It's like Heaviside and Co, lived in the quaternion version of Flatland. It makes sense why he wanted to drop what he saw as unnecessarily superfluous math at that time yet a little knowledge is a dangerous thing... and shortcuts can lead to dead ends.

I love Aldini

Pickering not Pinkerton 🙂

What is the point in this video? The bulb lights up 1/c seconds after the switch closes.

The story moves me because my father, who recently passed, worked for a while at Bell Labs, in Holmdel, NJ, and our the basement of my childhood home was filled with all kinds of electronic lab bench gear and jars of electronic components, including transistors. The resulting enthusiasm for understanding transistor circuits, got me into the gifted and talented program in elementary school. I learned a lot about electronics at a very early age in that environment, my father’s encouraged access to the ideas and the tools was key, and am still passionate about diving into the most subtle aspects of electronic theory and practice. I suspect there are many more hidden discoveries yet to be made by similarly curious, serious, and bold enthusiasts. Let these videos encourage more of the same! Electricity is where the action is, literally and figuratively. Optics is a close second, lol. Science is stuck in an axiomatic log-jam, raise a glass to the spirit shon here!

Oh, your history of electricity videos are so comprehensive and fun to follow, and your enthusiasm and warmth is so contagious. This detailed story-telling format of the rise of greatness and the controversies and challenges along the way, is the universal format to do such important innovation history full justice; this is a master class on how to present the history of ideas. A truly wonderful and exceptional production.

flowing through the wire is just "logical"????? not an argument

this has been elecetricfying - all amped up now

A large part of the video is ad hominem attacks on Lenard.

Kathy we miss you and learning from you!!! Come back soon :)

This produktion from is TéŁ Âviv. ¿¿¿¿¿

Never trust a woman who has mastered stabbing followed by twisting the knife.

This is why many homes didn't have electricity yet even after it was discovered years ago. Transformers still needed to be put up so that households could use the correct amount of electricity to prevent fires. Which actually did happen, there were several power surges early on until they got it right.

Kathy!!! You are a tremendous, positive, and passionate source of knowledge and information on the history and physics of electricity! I stumbled upon your videos, and I now plan to watch them all. Thank you so much for your passion and dedication and helping others love these things as much as you do. Cheers!

You can't mention Faraday without mentioning Maxwell and you can't mention Maxwell without mentioning Faraday -- one, the experimentalist, laid the groundwork for Maxwell to give Faraday's work mathematical rigor. And you also mentioned several others that contributed to our understanding. Scientists like Gauss and Coulomb and even Benjamin Franklin. There are few things in science that modernity depends on more than Faraday and Maxwell.

And still you look the same

Great video's and would be better if you got the spelling of names correct like Hindenburg and Meitner.

One of Kathy's best !

Can you *IMAGINE* getting a letter from Albert Einstein that begins, _“My Dear Kitten…”_ 😂

I can’t believe I just found out this wonderful channel! Outstanding work, I have spent a lot of time to connect science and history out of personal curiosity and interest, so glad to find someone with this passion and goal. You should be proud of your work Kathy 👏👏👏 absolutely inspiring summary you put together here.

Sweet!

Max Born is one of my physics heros Imagine my joy when I discovered that he was grandfather to one of my favorite actresses - Olivia Newton John.

Tesla destroyed his life himself.

Why were they playing with mercury? Was it not awfully dangerous?

5:10 del is usually called Nabla in Europe.

Hi Kathy, Great video. How do you get access to all the historical references and papers? Can you find them all online?

Wonderful video!! Thank you!

Please, Kathy, not corpsickles. Cor-pus-cles. Corpuscles. Otherwise excellent!

1705 - Haukesbee's generator made purple light. Inspired by a barometer. Flourencent light 1734 - Du Fay insulators 1737 - Bose - spark lighting alcohol on fire. 1741 - Nollet - electric egg 1746 - Leydon Jar 1747 - Franklin makes haukebe machine with brush. Incandescence. 1750 52 - lightning rod

You are amazing. It felt like I get to know a person. I liked your words, I liked the music and the contemplating end - in a strange but very nice way. I even turned on the subtitles. Thank you or danke schön in German :)

1:13 said from the perspective of a wealthy privileged white American. ask a black male/female American in the 1960's which was more important to him/her: Maxwell's equations or the outcome of the civil war. talk about out of touch...

So it makes sense that Walter worked with Nazis in Season 5

Not even cleaVage??

Watching your videos has been most valuable. Impeccably scripted. 🙏

like the screen on the glass in the door of a microwave oven

Buen video, me hará salvar el semestre!

I always thought it was Cyrillic E for the equations of Maxwell and then we used Greek epsilon for others

Exactly! I had a thought experiment that would place a 1 meg resistor a mile away. Would the bulb light? No. Permittivity is about 10^-11 per meter. That power pulse outside the wire does nothing. This was click bait. They want to shock (not electrically). I use wires in my circuits. Electrons flow inside them. This is not microwave.

If you die before me, can I have your brains❤️❤️❤️❤️❤️❤️❤️😂😂😂😂😂😂😂

Marconi stole from Oliver Lodge…so honestly, I don’t care, really…Edison stole from all kinds of people…it was the way things were, especially in the early days of electrical and electronics engineering history…

Kathy, you channel is too valuable from a pedagogical and epistemological point of view to leave it aside. Come back!

You rock. Love your channel

Three vectors force electric magnetic. If you get beyond mega rotation.

What a great video!!!

Excellent video! I’m glad I found this channel
