You are quite correct, In the mid-18th century most people thought that churches were burning down because God was showing his displeasure with the congregation. Franklin thought it was because the churches, with their spires, were usually the highest buildings in their locals and that lightning, not the Almighty, was causing the fire. Franklin installed his lightning rod in the steeple of Christ's Church at 2nd and Market in Philadelphia. You can still visit that historic church today in Olde City Philadelphia.
I am so sorry. I accidentally said that Leiden was in Germany in my Leyden jar video and I was determined to not mess it up again and then... I messed it up again! I apologize - don’t know where my brain is. Thank you for correcting me.
Wow! My mind is always blown. 🤯 Once again I learned the answers to many of my questions. I always wondered how they even came up with stuff in the first place!? That glowing barometer and the giant battery in the basement that helped them discover a bunch of new elements! Wow. Thank you so much. 🙏👏👏👏✌
I wanted to say thank you for these wonderful videos you've been posting. It's a shame that your audience is not bigger than it is, your content and presentation is great and definitely deserves a much larger audience. But I hope you continue to make these wonderful videos!!
"... who got bored with rubbing tubes by hand." Georg... Georg.. Georg... ;P Pieter van Muschenbroek was a Dutch man, from Leiden. Between Amsterdam and Den Haag.
Great video! You covered a lot of ground with this one, and I really enjoyed it. That BBC documentary is fantastic and I highly recommend it. I wasn't aware it had any factual inaccuracies, but it's still worth a watch. Dr. Jim is one of my favorite science personalities and watching him duplicate many of these experiments on camera was delightful, and it reminded me of your channel!
I thought his video was beyond beautiful and I love seeing all the experiments and his presentation was great but I think I’m like a lawyer watching Low and Order on tv, I keep on yelling objection! That video in particular had a lot of inaccuracies in my view (for example, Gray did not electrify his flying boy with an electricity machine, he electrified him with a charge tube and the electrified boy was the demonstration of his theories of electrical conduction not the reason he came up with a series of electric conduction) and it drove me nuts.
Thank you so much for making this channel, I just found it and I'm loving it so much, learning about the history of the people behind the science makes it easier to understand the science better, interestingly.
All of the illuminators prior to LEDs had some major room for improvement. Have we now reached a level of perfection such that there will no need for new sources? The appearance of addressable LEDs allows for nifty new applications opened to amateur designers, but even these are not major improvements to the basic technology. So have we reached the final lighting plateau, or will there be electric wall paint, addressible drywall, glowing porcelain fixtures, piezoelectric chewing gum and other wonders to supplant the LED?
the ultimate efficiency limit has not yet been reached. laser based illumination systems for instance have the ability to supersede LEDs in efficiency and intensity, as is presently seen on a few high end luxury car headlights. Beyond this in the far future, laser based high harmonic supercontinuum generation sources may ultimately become the dominant technology, but beyond a time horizon of a few decades it's impossible to say what light technology could become. What is certain is that the stupendous increases of efficiency and affordability of creating artificial light (over a factor of a million since the days of the oil lamp in antiquity. see William Nordhaus - The Cost Of Light) will undoubtedly continue for some time to come.
geez, I'm totally buying your book, Kathy! I'm huge fan of your work! History of science clears up so many gaps in conceptual understanding, I'm amazed.

Your videos on electricity & history are absolutely great! However, your geography skills could use a little improvement. 😉 Pieter van Musschenbroek was a Dutchman (like me) from the Dutch city of Leyden (nowadays Leiden).
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
These other clips of you doing experiments with family or friends, shows me that you would be a fun teacher. I'm close to your age, and my late father would bring science home from his job at the research and development center at GE.
Love your videos. Plan to watch them all! Thanks for sharing all this interesting knowledge and wisdom. I'd love to see a time travel television show that uses your stories to recreate the actual events in scientific history!
9:40 Is interesting. Had she been allowed to continue her research and combine it with Davy's work on giant batteries, (Aka "capacitors") then Today we might be harvesting voltage out of storm clouds, for use as a domestic utility, instead of just producing it at power plants. 🤔 (Note I said "just").
I had no idea Franklin discovered (albeit very fleeting) electrically induced incandescence. I am continually stunned (shocked? 😁) at how often historical scientific discoveries were repeated and forgotten over and over again, with no telling which rediscovery would ultimately 'stick' and become the one cited as THE discovery moment in history books.
You really should change the title of this video to "Early Electricity 1705 to 1809". You don't even mention the electric light bulb once within this video. Your title is kinda clickbait. I only watched this video to hear your take on the priority war for the invention of the light bulb - you know, the whole Edison vs Swan vs the other guys thing.
Pieter van Musschenbroeck was a Dutch physicist from Leiden and professor at Leiden University. Leiden is a town in the Netherlands. Not Denmark. If the rest of the research is also so well researched I doubt the value of these videos.
So the town of Leyden spontaneously moved from Germany to Denmark now? Or the other way around, Im not sure of the date on the other video... It's located in The Netherlands, by the way.
This video at 10.30 mentions the movement of dead 🐸 frogs, and it reminded me of a story my late mother had. My mother was in a class with a girl that was sort of a local celebrity, because she had made it on the cover of LIFE magazine back in the 40s and the other students rigged her dissected frog to move without her doing anything, and this girl was mortified to see it seem to come to life, but she wasn't in control of it. Everyone else got a laugh.
is that light in the gold leaf really incandescence? means it gets hot enough to emit light? its hard to imagine for me that such a good conductor would heat up with such a little asn short burst of energy, may be it is so thin, is it? I´d dare to say it is not heat involved here but sort of a gas discharge like exiting electrons to go up and down in such thin layer of atoms
@@Kathy_Loves_Physics I know this video is a year old now, but I have a question about 8:55. I don't understand what you mean? Surely you are not saying that the experiment drew _no charge_ out of the storm cloud? If not, then can you repeat where it _did_ come from?
I actually have a lapel mic but it was hidden under my shirt and I think I hid it too far away from my mouth. I will try to do better with the sound sorry
Georg Matthias Bose's relative, Heinrich Bose, used to host Johann Sebastian Bach often and was godfather to his children. Today the Bose house is the Bach museum in Leipzig.
I think I should find a way to sneak that clip into every single video and make even if it’s about quantum mechanics or the laws of thermodynamics or radio history. I should just always have me lighting alcohol on fire!
Maam love you respect you ...I did my graduation in science in 1997 but never got my doubt cleared...contextual study which i was desperately looking since ages and here in this channel i got what i was looking for and got my perspective clear. People in India need to get beyond rote learning to transform from developing country to developed country.Thanks for the great service.
Kathy. I have noticed that when I pull the protective cover of my nasal strips in the dark, a blue light is produced at the point of separation. What's up with that?
It's a phenomenon known as triboluminescence. It is shown in several videos here on YT. Back in the day when pictures came from film, I noticed that the end of the film was always exposed (to light) and appeared dark when developed. I found out later that the exposure came from light produced when I removed the tape that secured the end of the film to the roller on which it was wound. Fun times, back then!
Love your videos... They're awesome 😊... On another note... If Galvani had battered and fried those frog legs, he would have beaten Pied Majorcanis Esq. by one hundred years as the first person to fry the delicacy frog legs... 😜
Of course Galvini's experiments with the frogs legs (No French jokes please) gave rise to a young lady writing a story about the life giving powers of the electricity plus a whole plethora of films; the young lady was Mary Shelley and the book Frankenstein. Since Benjamin Franklin was one of those wretched rebelious colonists his work on using pointed lightning conductors was decried as nonsense and ignored in Britain. The effect on church spires, being some of the highest points at the time, of ignoring Franklin's work can be imagined.
Great videos. You can ignore me as I am just picky. At around 8:56, you said it is not draining electric fire from the clouds but induction instead. However, they seem to be the same thing. And it eventually drains the electricity from the clouds anyway.
I've really enjoyed your videos - thank you. The way you did the dates in the corner on this one was excellent - didn't stop the flow but kept us aware. Very James Burke indeed!

Kathy your work is incredible and you have done your homework. Very interesting. Great great job.
Can the title be changed? It clearly ends at 1809, not 1909, and the antiqueness of 1705 to 1809 against 'light bulb' would be more clickbaitish
