Kathy is amazing.

[@aaax9410]

On ya Kathy , i love your enthusiasum ❤

[@punditgi]

We love Kathy! ❤🎉😊

[@Raphael_NYC]

Kathy ; you are the best. You two are making so many people happy.

[@nathanrussell2158]

Kathy and Dave together. I think I’m going senile. Too good to be true.

[@Kathy_Loves_Physics]

If things being too good to be true = senile then that sounds pretty nice to me. 🥰

[@clazy8]

She's so fun. What a golden age for tinkerers back then!

[@raymitchell9736]

Two of my favorite KZbinrs! Lovely and enjoyable! Great stuff 🙂

[@user-mi6yl3hm1z]

It is so sad that this is rushed to just the hour. Even my friend who wasn't listening to the story was amused by how much energy is in your voice. I'm so going to read what happened with the bright CRT from my copy of your book. Hope to get it signed soon.

[@Kathy_Loves_Physics]

Sorry to say that this information is for my third yet to be written book. But I have much of it in individual videos with the same crazy energy 🤪

[@richardschaffer5588]

When I was a kid in the 1950s the shoe store had an X-ray machine. We kids loved to look at the bones in our feet inside the shoes!

[@mach1driver]

Thank you, now I have the proper name of what I called a visual migraine- "scintillating scotoma" and have had on and off for over 30 years. I love your videos, and have your book!

[@InssiAjaton]

Not Philco - it was Philbrick, where Bob Pease worked with some of the earliest op-amps. The other electronics guru was Jim Williams.

[@EEVblog]

Thanks for being on Kathy, it was great fun!

[@lourias]

Kathy, this is the FIRST conversational video i have watched to the end. .. i hope some day to meet you. We can swap stories about our hearing dylexia-type issues, LOL. You are a wealth of information and your passion shines brightly! Keep on keeping on!!!!

[@Chris_at_Home]

My first job in electronics I worked in a TV repair shop part time when I was 16 in 1969. I was a geek before they invented that word. It was also the same year I dated a girl named Kathie that is my wife. I ended up working in electronics and telecommunications all but a few years until I retired.

[@jafinch78]

Looking forward to the history of the all electronic camera designs history as well, since I believe is related if I'm remembering correct. Didn't study really specifically and was only from random readings regarding the CRT tube design or maybe there was more than one tube design image capture device? Great as always.

[@Moletrouser]

First commercial CRT - Mazda 1930 (intended as an oscilloscope tube, I think).

[@flvnow]

Karl Ferdinand Braun invented the cathode ray oscilloscope, and didn't patent it because he felt it was too important to limit.

[@cshubs]

Y'all should check out Farnsworth's appearance on the I've Got a Secret tv show.

[@Kathy_Loves_Physics]

I’ve seen it! Amazing right?!?

[@cshubs]

@@Kathy_Loves_Physics I'm happy to say I was a contemporary of his for 2 years (he died in 1971). TVs/screens will be with us for the rest of human existence.

[@myuncle2]

Kathy, a big request on you explaining the history of computers, and how everything started almost accidentally with the Stibitz half adder. History of science is so underrated, but is essential to understand complex things. In fact, the first Stibitz half adder was made without any valve or transistor, but just relays. It would be great if you made a video explaining the passage from relay to valves. Stibitz adder was so important, and paradoxically was considered unimportant by his supervisor😅.

[@Ed_Stuckey]

Shoe store imager: *fluoroscope*

[@alicangul2603]

This is too good to be true as other commenters pointed out! For me this is the highest point of KZbin!

[@alicangul2603]

I would love to read your book Kathy, but I'm not sure if it will ever be translated into my language...

[@Aisi555]

But if it wasn't david sarnoff and RCA, then there will be no tv broadcast via airwaves

[@toddb930]

I was thinking the CRT was based on the vacuum tube. The addition of plates on either side of the electron beam then steered the beam accordingly.

[@hallkbrdz]

Whenever I hear the name Philo Farmsworth, I think of Weird Al's UHF and the alien character at the TV station. LOL I agree about Engineers, we're weird. We like to know how EVERYTHING works. If we don't, it bugs us.

[@CarlVanWormerAE7GD]

Piease worked for Philbrick, not Philco.

[@davidg4288]

50 wavelengths of gamma rays!

[@anthonyshiels9273]

Just ordered the book. Due in Ireland before Jan 8th...

[@Kathy_Loves_Physics]

Thanks 😊

[@sandybarrie5526]

I actualy own a Marconi TV camera from the early 1950’s, but it is missingthe Vidicon tube.

[@christianduval8374]

🎵Electricity, 🎶electricity

[@Sam_on_YouTube]

Think anyone who doesn't know what Kathy does going to click on this expecting to hear about how Lucy and Desi developed Jackie's idea of the sitcom into the 3 camera format that persisted for the next 6 decades?

[@datman220001]

Halloween is actually an Irish thing

[@danielkaranja7978]

I think Philo Farnsworth had an ancestor tangentially involved with the Mountain Meadows massacre in Southern Utah.

[@jimsteele9261]

Yeah, after the game he talks about the future of TV... stuff that sounds a lot like HDTV, digital compression and the subchannels here in the US.

[@BlAcKpHrAcK]

Canadian wartime contribution to computer science: The "Either" logic gate, adds XOR to Boolean logic, using correct nomenclature. "Both" provides a logical implementation of NAND suited to Boolean logic. One might also make the logical series, either, both and neither. The handle BlAcKpHrAcK, predates the World Wide Web (dial-in bulletin-board systems).

[@Chris_at_Home]

I was taught Boolean algebra in Naval Avionics School in 1972.

[@christianduval8374]

Repeat after me: COR - PUS - CUL

[@attiknadjah8007]

pls the history of computer

[@richardfoster2895]

How about Octoberfest or is that too German

[@lawrenceharris7717]

Remember the IBM techs. They wore blue suits and ties but had to tuck their ties into their shirts to keep from being hung if caught in printer’s and tape drives.

[@VEC7ORlt]

Wow, Dave doing actual content, instead of his usual trash debunking solar roadways and dumbster diving.

[@EEVblog]

You do know that there are other people that like that content? Right? And it might surprise you to learn that there are also people that don't like discussions like this too, and that's just fine, everyone has their own interests.

[@VEC7ORlt]

@@EEVblog Sure thing, its just you stopped doing actual electronics and just started pandering to the lowest common denominator. Do better then, but I guess dem clicks/views are more important.

[@taynecooper7747]

With you on the Halloween thing, too much slavishly taking on American customs

[@NormReitzel]

Kathy, I met Richard Feynman at UIUC in earlY &)"S _ hew was so bRIGHT< he "shown". As another enginbeer, it was immediately clear that I was in the presence of gebius. One cOULD tell!

[@mikef4077]

Sorry madam your analysis is completely wrong.

[@keacoq]

Yes, no Halloween
