How the First Electric Lamp was Created in 1705: & Light a Florescent bulb with Static Electricity

[@adriansdigitalbasement]

I had never heard this history about a mercury vapor vacuum bulb, how cool. I’m definitely going to rub some plastic wrap on a fluorescent tube now. I remember as a kid being in a huge thunder storm and the fluorescent tube in my flashlight (yeah this was the 80s and it had a small cold cathode tube) would flash in sync with the lightening. I was fascinated.

[@Kathy_Loves_Physics]

That is so cool

[@JeffBehary]

Hauksbee's experiments have for me surpassed both Tesla's and Franklin's as beyond beautiful. He was such an ingenious inventor. His book of Physico-mechanical Experiments is an absolute treasure chest of inspiration. He deserves a lot of more credit than he is given, hopefully time will do him justice!

[@Vdacnh]

love your videos. keep teaching you have a gift truly. As a student I highly appreciate it and wish some of my instructors were like you. You're awesome Kathy!

[@Kathy_Loves_Physics]

Veronica Delgadillo thank you so much Veronica! ❤️😊

[@Muonium1]

Remarkably, over 300 years after its discovery, the underlying mechanism of the phenomenon, triboelectric charging, is so supremely subtle that its explanation still evades us at a fundamental level.

[@zes3813]

no such thing as high low or class or etc or unworthy or etc or obsequious or hire, good etc about it

[@antonionicotra7189]

I love and enjoy your work, your tales about science. I use them for my class. Thank you.

[@1945jlee]

I'm going to watch every episode just like I watched "Connections" back in the eighty's... Thanks Kathy...!!!

[@pixxelwizzard]

How do you learn all this stuff? You are a seemingly endless repository of fascinating anecdotes. You would be an amazing dinner guest! Thanks for this series.

[@jdwc1043]

I love this video series! Great work.

[@Kathy_Loves_Physics]

jdwc1043 Thanks so much glad you liked it.

[@quinto3969]

Kathy you're awesome. The depth of your research is crazy!

[@Kathy_Loves_Physics]

Thanks

[@ibrahimhussaini2701]

I wish you were my physics teacher when I was in school....you make me feel your student madam...thanks for your effort..

[@Kathy_Loves_Physics]

That makes me smile. I am glad to be your Physics teacher online.

[@barryfleischer6553]

You're keeping me glued to KZbin ! These videos are fantastic......I can't get enough!

[@Kathy_Loves_Physics]

Thanks I’m happy to be destroying your free time.

[@DataWaveTaGo]

This is the most delightful channel for science!

[@Kathy_Loves_Physics]

Thanks!

[@sammyasher]

Wonderful pedagogy, thank you

[@markbernier8434]

You can get a fluorescent tube to light brightly in mid air in a electrical substation. There are a couple of vids showing power workers doing this as a demonstration of how dangerous it is inside the fence around the facility.

[@markhodgson7241]

For a short time, I lived in a house that was very near high-voltage transmission lines. The fluorecent tubes in the kitchen would glow spookily in the dark by themselves - just from the electric field from the power cables outside.

[@bmzaron713]

Wow, this is a really great video.. There aren't many videos on hauksbee and this one really covered so many great things!

[@zachreyhelmberger894]

Wow! Wonderful stuff! I had no idea Newton was such a stinker! I have a bachelor's in physics and thought I knew a thing or two about the history of science.

[@videolabguy]

A very illuminating coverage of this fascinating subject.

[@Kathy_Loves_Physics]

Thank you for the compliment and the pun

[@mnada72]

Loving you episodes. Thank you 😊

[@adamkinsey3139]

I sincerely request that you put a disclaimer on your videos: "WARNING: Very Interesting and may lead to unintended binge watching."

[@Kathy_Loves_Physics]

You scared me at first not gonna lie. 🤣

[@new-jj5il]

I love Kathy Teacher

[@Kathy_Loves_Physics]

Balavinayagam B T thanks dear

Thanks for a great video

[@floridaman6982]

I wish I got more math history in school, i would’ve discovered I loved stem so much sooner.

[@Kathy_Loves_Physics]

I am on a mission to reintroduce history to our science curriculum. It is so valuable

[@maximilianUTU]

She is soooo fascinating ! She just charged me up !!!😇

[@markspeyer8269]

Fascinating!

[@CharlesCarlsonC3]

Terrific video. I liked it better than the first one.There were of course some omissions, but basically I thought it was spot on. Alright now I want to go back and review the various characters. Thanks for making and putting this series together. Have you gotten any feedback from students? Or your intended audience?

[@Kathy_Loves_Physics]

Thanks, I think I am getting better as I go too (or at least I hope I am). I am chomping at the bit to get to the Leyden jar and the battery and even blackbody radiation! However, I am determined to stick to chronological order so it will take me a while. I am currently not teaching (focusing on promoting my book - which I am still editing). A former student told me that I am much calmer in real life but then a friend said I am calmer in the videos! I think that you (or someone like you) is my intended audience for my book. Someone who likes knowing the history of science. The book has a bit more details as well as a bit more colorful language and is aimed at adults. I decided that I would assume that anyone reading/watching me had no physics background but I hope that simultaneously it would still be entertaining even if you know a ton about Physics and Engineering. (optimism) With the videos I am hoping that it appeals to teachers so I skew it a little younger. Cheers, Kathy

[@Kathy_Loves_Physics]

By the way, if you don't mind me asking, how did you find my videos?

[@brucewinningham4959]

Very interesting & informative Katly. You are a Saint. The more I learn about the History of Science & Technology, the more I realize we were taught wrong in the public school system about this History. Seems like government ran schools have their own agenda to fulfill.

[@qwaqwa1960]

I like the painting!

[@imallrightwhosleft4832]

Brilliant as always. About Newton being prickly, cheap and mean. Can we get more information on these details? Thank you in advance . Cheers from India.

[@camilorivera4685]

These videos are great. Many thanks,

[@Kathy_Loves_Physics]

You are welcome Glad you liked it

[@jensschroder8214]

Fluorescent tubes can also be made to glow if you're running a really, really powerful radio transmitter. There was such a TV station on the West German and East German border. 50 to 100 kW on tv channel 3. But with the end of the iron curtain, it was no longer needed.

[@beeleo]

Hauksbee could also have put the tube and mercury vapor in the microwave oven to light. :P

[@noelcastle3986]

Another great video love your work ..

[@mrmcafeeboat2887]

You make all scientists video I love it I never seen such a beautiful explain about scientist keep it up and make such more video please ma'am.

[@datasailor8132]

As an undergraduate I worked on the campus radio station. At Christmas time we hung old fluorescent bulbs from the antenna stays in the tower and they glowed.

[@ralphmccolgan7879]

I love your videos

[@donphilp7511]

Loved it

[@yamspaine]

Your content is amazing. Entertaining and logical, seems so great I am convinced your fact checking is adequate.

[@mrx42]

Hi Kathy ! Thank you for your amazing videos about the story of electrecity. I have noticed you used videos from the series of documentaries: "Great dates in science and technology"(i.e Otto Von Guericke). I am looking for all of them. Do you know how I can achieve it ? Cheers

[@Kathy_Loves_Physics]

I gave a link in my last video but it turns out that video that I referred to was illegally using the video!! (you are allowed to use small bits of copyrighted material if you reference where you got it from and you’re not taking away from their site which is what I was trying to do). If my memory serves it was done by the public broadcasting system of Germany but I can’t seem to find it on KZbin anymore. I i’ll keep looking as they were very well done and I would prefer to points to the original source.

[@Kathy_Loves_Physics]

I found another link to I think the same video but my guess is it is also not the original source so I don’t know how long it will stay on KZbin. kzbin.info/www/bejne/p5KZXqKFncpml7s

[@mrx42]

@@Kathy_Loves_Physics Thank you Kathy !

[@erzahler1930]

I wonder if this influenced the development of the mercury vapor rectifier.

[@realvanman1]

The Cooper Hewitt lamp came well before the fluorescent lamp, and was a true low pressure mercury vapor lamp without phosphors. The UV lamp shown glows violet because it is made out of Woods Glass, which blocks short wave UV, as well as most of the visible light, allowing only the long wave UV to pass. The first mercury vapor lamp would have had a blue glow rather than purple.

[@jamesslick4790]

"The Electric Kisses" is a good name for a band.

[@priteshkumar3078]

I love ur knowledge

[@Kathy_Loves_Physics]

Thanks

[@jag12549]

I don't laugh aloud often But I seem to at least once every time I watch one of your videos. You should try your hand at comedy. Your deadpan delivery is killer

[@billmacrae1924]

Excellent presentation, but the background music is distracting.

[@amitpatil5151]

Accidentally Thumbs Up.... as 99.99% of discoveries were accident.👍

[@sjamesparsonsjr]

Does anyone have a video link of a Hauksbee generator (globe) in action?

[@Kathy_Loves_Physics]

There was a PBS show called “shock and awe” That had a hawksbee globe in action

[@CorneliuZeleaCodreanu9]

nice smile

[@nalin31081]

I hit thumbs up accidentally

[@mogret7451]

🤗

[@AlexanderShcherbinin]

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

[@bluefishactcl1464]

Where did you get that Newton was cheep and did not pay his assistant widow?

[@stevejohnston3194]

Just checked... When I rub a fluorescent bulb against a polyester pants leg in the dark, it lights up faintly and intermittently.

[@Kathy_Loves_Physics]

Nice. It just doesn’t film very well which is very frustrating to me.

[@lightninrodpbn]

PROFESSOR, I CAN'T HEAR YOUR EXCELENT TECHNICAL PRESENTATIONS BECAUSE OF THAT '' RACKET'' GOING ON IN THE BACKGROUND .... :-( .......... .............................................................................

[@49commander]

Are you a school teacher or College Professor?

[@kirstenspencer3630]

Thanks for the story of how cheap Newton was, he' off my Christmas card list forever !

[@rhoddryice5412]

Newton was a real PoS, wasn’t he?

[@arnesaknussemm2427]

Unknown causes….Mercury??? Hmmmmm….

[@davidcolver2502]

These wonderful videos need no ornamentation; the music merely serves to distract, and in this one is loud enough in places to make the narrative hard to hear.

[@Kathy_Loves_Physics]

Sorry about that, I thought it would be more entertaining with a little background music but after enough people complained, I realized it was just a distraction, and I stopped putting background music in my later videos. Maybe someday I’ll figure out how to remove the background music from the old videos but for now, I’m sorry.

[@Simonjose7258]

Is a woman who has sex with the KING really "loose"? Or just Ambitious.

[@Kathy_Loves_Physics]

For most of history ambitious == loose for women. 🤷🏻‍♀️

[@priteshkumar3078]

I love u

[@marzymarrz5172]

Newton was a creep. I wish I had known this when I was a kid. I could have annoyed every science teacher I ever had.

[@Kathy_Loves_Physics]

I’m guessing that you were like me and annoyed every science teacher you ever had even without this fact. 🤣

[@clivebradley2633]

Do not refer to our parliamentry revolutionaries as thugs. Compared to the GOP they were angels.
