In 1968, I built a Tesla coil based on a plan in Popular Science magazine for my high school science fair. That same year my English teacher required us to write term paper and I chose Tesla and his inventions. I could only find one biography of Tesla in my small town library, and about three sentences in encyclopedias in my school library. Mostly the biography repeated some of the "stories" like Westinghouse begging Tesla to forgive the $ per horsepower royalty. Later in life, I realized that the source for the stories were the memories of and old man, probably embellished to make himself look good. Your observation that Tesla was an "electrical artist" is concise and to the point. He couldn't balance a checkbook. 😁 Thanks and keep talking to us.

[@jeffbehary4323]

I really enjoyed this one Kathy, especially after archiving more than 6500 original letters and documents of Tesla from Leland Anderson's archive and realising the stories we've heard over the decades were far from accurate or even made-up. No doubt this video will get criticism from Tesla fans but I really hope they would consider stepping back a moment and looking over the real documents and discussions and always demanding the proof for anything they read as opposed to accepting facts blindly. Tesla had a group of people working for him that don't tend to get a lot of credit in books, and similarly his work was perfected by the brilliant staff of Westinghouse of which he held a very high regard for (and vice-versa). He also did consulting work for Westinghouse, William A. Anthony, and others and helped them develop their motors in addition to picking their brains on various topics to improve his. He also interviewed a lot of people over the years and recommended them to Westinghouse for jobs. He did a lot we don't know about. A lot of people focus on the battles but there was far more respect and cooperation between all of these entities, Tesla was not a one-man show. My only criticism, you actually can generate nitric from high frequency discharges (or electrical discharges in general). Similar to how oxygen can get converted into ozone, nitrogen compounds are also formed by sparks. A fun fact, in the early days of X-Rays Kinraide thought that the X-Rays were not causing burns but rather the nitric generated from the corona discharges of his machines. He described soaking his arms in baking soda solutions to try and neutralise the acid to avoid them, which helped to some extent. Unfortunately the X-Rays in addition to the nitric compounds were causing burns...(the nitric acid burns, the X-Rays keratoses) in the end he burned a young woman making repeated X-Rays of her to perfect his machine and ended up marrying her out of obligation not being sure if she would survive the injuries or not. The irony of the story is that she was much younger than him, he was actually more interested in her mother who he had a relationship with since moving to the US from Canada. (They all lived in his mansion in Jamaica Plain). The younger bride recovered and became a high society girl and decades later when she wanted to separate from Kinraide went to the press and told them her husband was having an affair with her mother since their honeymoon. Needless to say the case received a lot of publicity as the "most sensation separation trial in Massachusetts history". The story gets more colourful but not for all ages... Kinraide and Tesla incidentally also knew and respected each other and Tesla used Kinraide's phosphorescent screens when he did his X-Ray and Lenard Ray research in 1897. And when Tesla filed the patent for Wardenclyffe, several claims of the tower design were thrown out by the patent office because of Kinraide's prior patents. So Tesla fans, before you get angry realise there are many stories in the lives of these inventors we don't know or that surface that change how we perceive things. And that's what makes history so much fun...

[@Kathy_Loves_Physics]

Jeff, that is fascinating about the nitric acid! I was particularly irritated with the fertilizer thing was because in 1900 William Crookes gave this big speech where he said if we don’t figure out how to get fertilizer out of the air then western civilization will collapse so it was the big problem in chemistry at the time and the reason that we got the third law of thermodynamics as well as chemical warfare in World War I. it’s a crazy story. Anyway, because I knew that history I knew the whole let’s get nitrogen out of the air and make fertilizer was not something we could do with a spark. But I didn’t know about nitric acid.

@@sonofkabisch Edison’s greatest invention was the modern industrial laboratory. Bell Laboratories was very much like Edison’s research labs in Menlo Park, and East Orange. Edison assembled teams of smart people and had them all work together and the results were incredible. Since then many other companies have created such laboratories. Edison’s approach was adopted by many other companies, and resulted in things like telecommunications, satellites, lasers, and the transistor. I think the days of Edison worship are long gone, and we now live in a world that likes to demonize the man.

As an electrical engineer having 60 years of experience with R.C.A., A.T.T., U.S.N., P.G.E., and L.A.D.W.P. and having read both of Charles Steinmetz’s major works, A.C. Phenomena and Transient Phenomena I believe I am qualified to comment on the subject at hand. I have observed three KZbin presentations in the name of History & Physics, one on Steinmetz, with glowing accolades, and two on Tesla, with sneering contempt. Not being a creature of so-called social media, by nature I do not involve myself with it. However, because of what I am watching, I feel that I must comment on behalf of my profession. I see here what resembles a “livestock stampede,” an aimless and incongruent flurry of comments scattering the facts of the subject. Here are the facts of Polyphase: The defining condition for the number of phases in a Polyphase System is defined by the number of conductors required to support the balanced and symmetrical condition of the system, this excluding any so-called natural conductor. A corollary condition is the flow of electric power in this system must be continuous, not pulsating. Accordingly, three or more phases must exist in order to engender the Polyphase condition. The currently adopted system has three phases, A, B, and C. Neutrals are optional. The Tesla-Westinghouse System has four phases, A, C, and B, D. The domestic alternating current system, two wire, neutral optional is hence not single phase, but in reality is two phase by definition, and consequently is not Polyphase since its power is pulsating, it is not constant. “Single Phase,” is not possible in the J. Clerk Maxwell viewpoint. The advantage of Three Phase is that it uses the least amount of “copper”. The disadvantage of it is that no alternate sequence exists so accordingly any two wire load creates an imbalance hard to compensate. The advantage of Four Phase is that it is two alternating sequences in quadrature, thus lends itself to application of two wire loads. The disadvantage is that because it is made of alternating sequences, pulsation remains as a “residue,” leading to more vibration in machinery.

Unfortunately Tesla got the limelight usually via 3rd parties for "developments" that could arguably be put down to "other" engineers of the day in my opinion Mikhail Dolivo-Dobrovolsky was crucial in the advent of the 3 phase motor but the limelight was not really in Europe at the time at all hence next to no recognition. Regardless of Teslas "faults" he was definitely was one of the main driving forces of electrification process in the late 1800's that may not have happened had he not "been around".

3:51 That is a common railroad frog found on every switch or rail crossing and is much older. The device used to put derailed trains back onto rail looks completely different and is called a rerailer. The image of the patent you show in the video is a railway frog made from one piece, to which you can attach rails and it is certainly not used to help derailed trains get back on track. It is a one-piece frog, I have seen similar designs used today for streetcar applications (especially in designs where the wheels run on their flanges over frogs), but this "one-piece-frog with attached rails" is not common used by the railway. Westinghouse maybe patented a rerailer, which he called "car replacer" back in 1867 or 1868, but I could not find the document, as google patents shows his patents only from 1874 upwards and the sources mentioning the 1867/1868 "car replacer" are not trustworthy, maybe they just repeat some made up story, as there is no reference, nor an image.

It seems that Siemens and ABB have worked out the switchgear to control this. The article speculated on the possibility of building world wide grid with DC transmission. The idea is that solar energy could be transmitted from places like Australia to, say, Southeast Asia, with little loss. It is interesting how things progress.

Love your vids Kathy and have learned soooo much! I was just curious though......why have you not done a video on Farnsworth yet?

[@Kathy_Loves_Physics]

I’m sorry, I have been planning on getting to Farnsworth for years now and I keep on getting distracted. He’s still on the list, but I am easily distracted… So sorry.

[@jefffoster3557]

@@Kathy_Loves_Physics No problem.....I can easily understand how! Lol. Got your hardbook in my Amazon cart.....looking forward to it!

Kathy.... there is a misconception that Thomas Edison had only a 8 grade and knew nothing of physics. Edison had not "formal" education, but he studied lots of physics by himself with the guide of an uncle and friends and knew lots of physics. His more spectacular invention the phonograph and electric light requires a good handling of physics. The electric bulb was the principle of the the electronic valves that made possible radio & TV, and later computers

[@Kathy_Loves_Physics]

He was also a very good chemist, and supposedly preferred chemistry over physics. Supposedly, he learned a lot from faraday which made sense because neither Edison nor faraday used much math.

[@fdewiii]

Well said.

[@donpeters9534]

Thank you for your clarification and rectification of history and the myths surrounding Tesla. It is a shame that main-street media cannot be as thorough in the research of their erroneous stories...

[@topos100]

The point is that Tesla built stuff...and people who make youtube videos about Tesla...haven't built anything. You cannot compare a video with Niagra Falls.

[@fdewiii]

I am going out on a limb, because I haven’t researched it, but I don’t think Tesla built Niagara Falls

[@dancanzna3221]

Thank you Kathy for this really amazing video. I just realised that I am also a victim of the myth around Tesla. And this myth is still creating consequences! My homeland, Croatia, is going to change its currency to Euro next year. Since Tesla originates from Croatia (but Serb ethnically), and obviously due to his popularity, the majority voted to have him as a motif on one of the Croatian Euro coins. So, he doesn't have "his" SI unit or car company only, but also will have "his" coin!

[@nicosmind3]

That's sad to hear, Croatia should keep it's own currency as the Euro has lots of problems and will cause problems

[@jagmarc]

I think Tesla would still be a good figurehead for a minted coin for the country that originated this great personality. The name Tesla is a celebration how humanity may well take a irregular path but in the end finds its way.

[@pinkiesue849]

Good! So glad someone appreciates what all Tesla brought to us, even if he didn't work alone!

[@shaun2072]

Brilliant work as always Kathy.

[@zhubajie6940]

Your best! I wish this was on PBS. But I'm partial to George because I once worked for the company until it went downhill after Siemens bought it out. (I remember reading Werner Von Siemens thought AC and polyphase would never get anywhere selling an alternator to Westinghouse).

[@y.u.208]

Responding here, dear Kathy, as you were kind enough to forward that link on my questions. ??? Still not smarter just more confused. My interest is getting the truth, as truth can bring balance & justice, what I think our todays' world desperately needs. How can mankind get truth if witnesses are gone? I am not in engineering or any related field, I just discovered Tesla couple of years ago, liked his deep quotes of wisdom & acknowledge a lot. As I see his name misused nowadays, guiding mankind into transhumanism and abuse of Mother Nature, I seek for truth as I believe that even after death there is chance of influence by the passed aways. Current times show me that there must be still open questions as our world & cosmo is in disbalance in many ways. I take your information given, as I see forming an opinion to find out truth must involve consideration of other opinions. Hope we get the truth one day by reflection of better now & future. "I know that I don't know anything" But If I don't ask, I will never get answers. Before getting stucked into unsolveable mysteries, I rather go for mutual agreement, If we don't get truth, better leave and start from scratch. Stubborness brings not solution, too far behind the past, too hidden some facts, we need to move on, on behalf of current situation and youth. Please lords help, and enlighten for peace, justice & balance 🙏🕯️🏞️♥🏞️️🕯️🙏

Our ubiquitous 3- phases - Star/ Delta AC distribution & most efficient Double Squirrel-Cage Induction motor are due to Dolivo Dobrovolsky.

[@Kathy_Loves_Physics]

Absolutely. I go into it and much more detail in my video and the history of three phase.

[@imeprezime1285]

3 phases, star connection-Friedrich August Haselwander. 3 phase sync. machines-F.A. Haselwander. 2 and 3 phase wound induction motor- Nikola Tesla Star/Delta connections- D. Dobrovolsky Cage induction motor- D. Dobrovolsky

[@susilgunaratne4267]

@@imeprezime1285 Of course, after the initial principle idea reached to the skilled engineers & technicians it was quite natural that many worked on it simultaneously without knowing each other in different countries. What we are against here is for the claims that attribute all such inventions/work to one person - Tesla. Usually the discover of the principle for the 1st time in the history can be easily identified but not the subsequent equipment, application developers. Final successful complete product developer may also get noticed but not the in between.

[@Istandby666]

Ever since I found out through research. That Tesla's tower was labeled as an Atmospheric Apparatus. More research found that other's were working on the same technology. This is why I've been looking for the truth. I became an Electrical Engineer because of Tesla. He helped me (the false story) find something that interested me.

[@puschelhornchen9484]

[@PhilOutsider]

This is great. Thanks.

[@johnopalko5223]

Thank you, Kathy. That explains a lot. I never understood how Tesla had acquired his cult following. He did some interesting things but nothing deserving of the near deification he now enjoys. George Westinghouse, on the other hand, has always been a hero of mine.

[@emancoy]

Strangely, Tesla was a vaporware salesman and now Elon Musk has also became one

[@johndannenbrink7590]

Hopefully I’ll watch this attentively in full when I have time. I would ask for now, has Elon Musk named one of his companies “Tesla” because he has believed wrongly about Tesla too? Or does he read the same text and interpret it differently without casting shade on anyone, preferring Tesla? Because you know sometimes words have two meanings.

[@bhami]

Thank you for setting the record straight on Tesla! p.s. 1:01:10 The word is pronounced high-PER-bow-lee, not hyper-bowl.

[@eigenchris]

It's crazy how all of this Tesla-mania started within my lifetime. I heard people talk him up in school and just assumed they were right. Looking forward to the quaternions video! (Hopefully there will be fewer eugenicists in that one!)

[@letMeSayThatInIrish]

Elon Musk should look into that equatorial dirt ring. Seems right up his alley. Maybe run a hyperloop through it as well🙂

[@williamwoolcock]

Westinghouse made his money on "Westinghouse Air Brakes" which revolutionalized the railroad industry, still prominent today with a huge factory In Pittsburgh. He had a sort of side interest in electricity. But he made megabucks on it. Didn't Tesla fall in love with his pidgeon?

[@SocratesAlexander]

It's interesting seeing such a huge dichotomy between engineer biographers and non-engineer biographers with regards to Tesla

Funny how I did not get it before. The electrocution of the elephant is a movie and there were no movies during the war of currents. They became only in 1895. Often when people view past events they do time compression. Looking from 2022 1890 and 1903 may look almost the same but back then the difference was same as 2022 and 2009.

[@plankton50]

I will never forgive Tesla for making possible the most wretched of human constructions. The cage of doom.
