[@noxabellus]

Ok I'm not religiously offended like some in these comments but it is *very odd* you didn't mention Tesla, considering you talk about Westinghouse and _he is often credited with the invention of AC_ ... Regardless of whether you'll be covering him in future episodes, its a huge oversight for this video as a unit.

[@Udontkno7]

He finna have his own episode. Like Shakespeare in the theatre series.

[@AlipashaSadri]

I think this video had a nice logical consistency. There was no "he invented AC"; it was "Edison's DC versus Westinghouse's AC". I think the context here clearly implies that he is talking about industrial production and "brands"; having mentioned that Edison was trying to create a market for electricity. Westinghouse was the first to generate AC and sell it to people in US. He used Tesla's patents in the process. So it was a rivalry between Edison and Westinghouse as far the "consumer" market is concerned.

[@Ceidonianphysicist]

Tesla didn’t Invent AC. AC was invented before Tesla was even born. He invented a specific ac motor which ended up not really influencing future ac motors that much. His legacy has been massively inflated by falsehoods developed by clueless people on the internet.

[@noxabellus]

@@Ceidonianphysicist Ok, well, if that's the case I think it only serves to solidify my core point that leaving his name out of this episode was an oversight.

One of those wires should be showing the magnetic field going clockwise. Both wires are showing counterclockwise. Use the right-hand rule your thumb shows the direction of the current and your fingers curl in the direction of the magnetic field.

Oh, btw. Edison didn't invent the light bulb. He "perfected" it.... and by perfected i mean he invented a version that would eventually blow, creating a need to continue buying them. (He saw potential for profit in light bulbs, but didn't like fact people would only need to buy them once every 10-15 years or so). *Humphrey Davy and Joseph Swan* were the real inventors of the light bulb, and yes, their version could easily last 10+ years. In fact, they were developing bulbs that would Never blow before Edison stole their research, and developed a much lower quality bulb. (They were actually 2 of the countless people who won lawsuits against Edison). This video has quite a few errors.... and btw yes, Edison was not an inventor. He was a ruthless businessman who was exceptionally good at stealing research (and credit).

[@narnigrin]

So many puns here that aren't even acknowledged. ... who first saw the _potential_ ... ... [bringing electric light to New York] was _blindingly_ amazing ... ... utterly _transform_ the world ...

[@TlogicoP]

This is a poor digest of wikipedia articles. 1) No one knew that lightning was 'energy', or even the same kind of thing as static in Antiquity. In general, electrical phenomena like static was widely considered a 'fluid' into the 19th century. 2) Many of the 'parlor tricks', like Stephen Gray's, served two purposes: to entertain, and to show something experimentally, i.e., that the human body is a good conductor. 3) Hauksbee didn't discover that spinning a glass sphere generated static. He built the device because he already knew it would work. People had been making tables of materials ordered by how much static they generated from friction since at least Gilbert's time. Glass was high on the list. It was actually a suggestion of Newton's to replace the sulphur sphere of von Guericke for better results. 4) The 'electrostatic generator' was not known as an 'electrical generator' because electricity itself was not a unified concept yet. 5) Benjamin Franklin and his circle were extremely prolific and DID CONTRIBUTE EPISTEMICALLY to the history of electricity. For one, he showed that both lightning and static could charge a leyden jar and perform the same experiments, meaning (to him and most others) that lightning and static had an underlying similarity. Joseph Priestley called this the greatest discovery since Newton's law of universal gravitation. 6) Galvani did not himself demonstrate the existence of 'animal electricity', which was part of the controversy with Volta. His more convincing proof appeared in an appendix to his last work in which he showed that you could get the legs to twitch without using metal connections. These experiments were popularized by his nephew, Aldini, after his death. 7) Galvani did not 'inspire Volta to push his work on nerves furthur'. Volta was not convinced of the existence of animal electricity. He thought the leg twitches were the result of using different metal connections. He invented the voltaic pile to prove this effect and disprove the existence of animal electricity. 8) Volta did not invent the first practical method of generating electricity. You already mentioned electrostatic generators. 9) The voltaic pile is not the first 'battery'. The term 'battery' was coined by Franklin to refer to a series of Leyden jars. They could store large quantities of charge. They just could not give you a continuous current. 10) Understanding the voltaic pile does not require knowledge that electricity and magnetism are related. It is a chemical effect. At Volta's time, it appeared that there were multiple kinds of electricity: static, lightning (though Franklin unified this), animal, and chemical. Magnetism and light were on the list, but only by remote analogy. 11) Faraday did not simply 'get to work inventing electromagnetic motors'. In fact, his famous electromagnetic motor was actually an experimental setup to prove the convertibility of magnetism and chemical electricity. He performed many experiments with different kinds of electricity to show they all produced the same effects, thus 'unifying' the pantheon. I don't have the energy to go through the rest. All-in-all, your history is extremely whiggish and poorly researched.

[@Musiccat1145]

No Tesla, No mention of Maxwell's laws. No mention of the Faraday cage. This should have been two more episodes.

[@narnigrin]

There _is_ mention of Maxwell's laws at 8:15-8:20. So yeah, there's literally _mention_, although not much more. :)

[@aspiahmacaurog4354]

Basically, electricity is one of the most important factor in running out an industry together with the development of economy. Actually due to the hard works and determinations of our inventors, electricity were develop little by little until electricity develop. It was actually Thomas Alva Edison who give a good idea of electricity in which resulted to the growth of industry, and economy of our country. And of course electricity gives life all over the world. I can't really imagine a life without electricity especially nowadays. Sir Thomas help us to see people clearly in the night.

[@SotraEngine4]

Applause for pronouncing ø right Also, Tesla was crucial in making components for alternating current (which will be what I'll blame on if I fail at the exam) Also, without alternating current, only the very rich could have afforded electricity.

[@Ganymedescup]

Mary Shelley's novel contains one paragraph mentioning electricity: "Before this I was not unacquainted with the more obvious laws of electricity. On this occasion a man of great research in natural philosophy was with us, and excited by this catastrophe, he entered on the explanation of a theory which he had formed on the subject of electricity and galvanism, which was at once new and astonishing to me. All that he said threw greatly into the shade Cornelius Agrippa, Albertus Magnus, and Paracelsus, the lords of my imagination; but by some fatality the overthrow of these men disinclined me to pursue my accustomed studies. It seemed to me as if nothing would or could ever be known. All that had so long engaged my attention suddenly grew despicable. By one of those caprices of the mind which we are perhaps most subject to in early youth, I at once gave up my former occupations, set down natural history and all its progeny as a deformed and abortive creation, and entertained the greatest disdain for a would-be science which could never even step within the threshold of real knowledge. In this mood of mind I betook myself to the mathematics and the branches of study appertaining to that science as being built upon secure foundations, and so worthy of my consideration."

[@Tfin]

[@Ganymedescup]

@@Tfin From context, it looks like "electricity and galvanism."

Yeah. Shelley, not knowing enough about the New Thing to write on it, just says that that's Frankenstein's field of study, and hand waves the details. There was another post saying that the story never says it was electricity that was used to reanimate the body, but that's the obvious implication.

"We are people that aware that the lightning is the powerful release of energy caused when two clouds are in love and make a baby cloud. But that's hard to study, much easier to study, was static electricity, or the electrical charge produced by stationary friction. For one, they had no concept of current, or electricity as a flow of electrical charge. Current can happen either by the movement of negatively charged subatomic particles called electrons through wires, or by the movement of charged molecules called ions." - according to him. Thus we all know that electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. In early days, electricity was considered as being unrelated to magnetism. However, another thanks for the one who discovered the current of electricity, it is very amazing that we have a source of electricity due to the water and also the lighting that coming from the down sky. It's a wonderful thoughts. Thanks ma'am for bringing us to this channel without you we can't watch these videos of crushcourse history of science:)

We all know that electricity is very important because it gives light and we can do things through the use of electricity. They used differeny weird parlor tricks that had no obvious uses. At the same time I was inspired with Francis Huksbee who found out in the early 1700s that spinning a glass glob produced electricity thus creating one of the first electrical generators. I am also thankful to Mike because he created the current in another world where it became the basis of the electromagnetic technologies that we used today. I'm not just thanking him but all the significant people who made and found out about electricity.

Everyone is losing it because they didn't mention Tesla.. And here I am annoyed that yet again Hauksbee and Ben Franklin are brought up, yet no mention of William Gilbert or Thomas Browne. A guy gets famous for one experiment and suddenly no one knows who discovered (and named) electricity. (Gilbert n Browne coined it in early 1600's) Edit: Also, just pointing out, we don't actually know if the kite experiment ever happened, or if it did, we have no idea at all id Franklin did the experiment himself. He certainly never claimed that he did. He only briefly mentioned it in a very brief statement to the Pennsylvania Gazette, saying, and i quote: "the iron rod experiment had been achieved in Philadelphia, but in a different and more easy Manner". He never specified who did the experiment, only that it had been done. He also never said it was the kite. In fact, it was about 2 decades later when Joseph Priestly wrote about it, that it was claimed Franklin did the experiment using a kite. Problem is he never witnessed it himself, and many scientists have pointed out if Franklin HAD done the experiment in the way Joseph described, it would have killed him. Aaaaaand, on top of it all, Benjamin Franklin was nowhere near the first person to do that type of experiment. In fact, that experiment had been done so much in the previous years (with a variety of objects including metal rods), that virtually no one even took notice when Franklin made his claim. He did write up the concept that electricity n lightning are the same... but as for the kite experiment, all we have as evidence is the word of someone who was not there, writing about it 2 decades after the fact, by simply giving his interpretation on what Benjamin Franklin would likely have done.

(Sure we all like to fancy that in such a future, a bit of electricity should be nothing to build a death star about,, but as with all growth, infrastructure projects also continue to get bigher, requiring more and more energy at once.)

Edison was a kind of Steve Jobs. Incapable of inventing anything on their own, but amazing at popularising ideas.

He was more than a Jobs, Edison actually worked on some of this stuff himself, Jobs was just a cash guy.

I was taught that, depressing as it is, it's more likely thatvFranklin's kite in a hurricane experiment was merely a thought experiment, and he (probably) didn't do it.

Alright everyone take a chill pill, they said they'd talk about Tesla in an upcoming episode. You know these guys and their love for knowledge, you think they'd casually forget about such an important figure?
