3, 6 and 9[edit]

Tesla had an obsession with the numbers 3, 6 and 9. He only associated with numbers divisible with three, like in how he only stayed at hotel rooms divisible with three. Though there is no section about this, I was wondering why that is, and if it should be added. --Year1888TALK 12:26, 27 February 2019 (GMT+1)

@Year1888: could you point to a (reliable) source or two that verify this? Along those (OCD?) lines, Tesla reportedly abhorred small spherical objects. I believe that was covered in O'Neill. - MrX 🖋 12:04, 27 February 2019 (UTC)
@MrX: I found a lot of independent sources from some quick searches. One could, for example, be from an article called "The Mindblowing Secret Behind The Numbers 3, 6, and 9 Is Finally Revealed!" from There is also a book on it called "Nikola Tesla and the 369 code". - user:Year1888 - 17:41 27 February 2019 (GMT+1)
I doubt that would be considered a reliable source for such an important biography. The book appears to be self-published, so I think it would fail WP:RS as well. - MrX 🖋 17:39, 27 February 2019 (UTC)
I agree with MrX. You can't trust that just because a "fact" about Tesla appears in multiple websites it is true. A LOT of myth and false information circulates on the web about Tesla, repeated by many fanboy websites. A reliable source would be a reputable biography such as Carlson or Cheney. --ChetvornoTALK 18:13, 27 February 2019 (UTC)
@MrX: I see where you're going with this, and you're probably right. There just isn't anything to completly draw the line and say that it is true, that Tesla was obsessed with 3, 6 and 9. - user:Year1888 - 21:50 28 February 2019 (GMT+1)

In the section Eidetic memory, there are five links referring to the same book. Isn't that a bit too much? If all sentences are derived from the same source, simply place one reference on the final sentence and in this way define the whole text. If several consecutive sentences refer to one source, link the final sentence only. This will simplify and clean up things a bit.

I haven't checked the entire article but this exaggeration with references is also true with section Early years:

In December 1878, Tesla left Graz and severed all relations with his family to hide the fact that he dropped out of school.[32] His friends thought that he had drowned in the nearby Mur River.[34] Tesla moved to Maribor, where he worked as a draftsman for 60 florins per month. He spent his spare time playing cards with local men on the streets.[32]

All three references (32;34;32) link to same book.

Next, there should be a separate section called, "Tesla's Thought Experiments", to further describe his ability to construct electro-mechanical devices in his mind. He has said that:

“My method is different. I do not rush into actual work. When I get an idea I start at once building it up in my imagination. I change the construction, make improvements, and operate the device entirely in my mind.” ― Nikola Tesla, My Inventions: The Autobiography of Nikola Tesla

The majority of his work took place in his thought experiments (in the laborytory of his mind). This is exactly what Einstein was doing when experimenting with the laws of nature. The only difference between Einstein and Tesla is that Tesla did thought experiments with machines.

This topic is briefly mention in the section Eidetic memory:

Tesla would visualize an invention in his mind with extreme precision, including all dimensions, before moving to the construction stage, a technique sometimes known as picture thinking. He typically did not make drawings by hand but worked from memory.

There should be a separate section as this ability is significant in Tesla's life and makes him a special character in the world of inventors.

Please respond,


p.s. Section Notes takes up 17% of the whole web-page... Marinoklisovich (talk) 20:42, 11 April 2019 (UTC)

To your first point, they are repeated since one of them points to a specific page in a book. This is preferable, it helps those who want to verify the information. It's also all right to repeat references for each sentence, it makes it more clear where the information comes from and is helpful for when editors want to change parts of paragraphs. Having a long Notes section for such a long article is quite all right. – Þjarkur (talk) 21:23, 11 April 2019 (UTC)
@Þjarkur: I didn't know that references go in such detail. Thank you for your answer.
@Marinoklisovich: His "mental development" process is mentioned in the "Eidetic memory" section, but maybe more should be said about it. As biographers like Carlson have noted, his failure to perform adequate development experiments and build scale models before attempting full scale projects is responsible for the failure of his Wardencliffe transmitter, and maybe other projects. This should probably be mentioned. In general he seems to have been too impatient or unable to do conventional engineering development, which probably explains why all his projects after 1900 were failures and he ended up destitute, when other similar engineers of his era ended up rich. Tesla was nothing like Einstein. Theoretical physics you can do on a blackboard since it is built on experimental physics, but in engineering you have to test out whether your methods work in the real world. Tesla was completely wrong about his "earth currents" theory of wireless, and stuck to his failed theory long after radio waves were proven. --ChetvornoTALK 21:39, 11 April 2019 (UTC)
@Chetvorno: I don't now about his later yeas but his invention of rotating magnetic field was conceived in his mind with no support from real lab. From my own experience, thought experiments are quite possible. After prolonged observation of reality (just raw experience), you can do though experiments. Nikola Tesla lived his whole childhood in a natural village, surrounded with by nothing but nature. He was underestimated a lot by academia and established scientific world. Anyway, a comprehensive article for sure.
@Marinoklisovich: Yes, his alternating current inventions (the induction motor which came from his rotating magnetic field idea, and multiphase power) were his only successful ones, perhaps because he was working for Westinghouse labs where he was forced to actually develop them into practical products. His record when he was working on his own, developing inventions by "thought experiments", is almost complete failure. Tesla was a wonderfully creative inventor, but he wasn't a scientist, an entrepreneur, or much of a development engineer. He failed to accept the scientific advances of his day and remained mired in 19th century misconceptions; he didn't believe in the electron, relativity, or even radio waves, and continued to believe in the ether and antigravity.
If Tesla was once underesteemed as you say, he is now WAY WAY overesteemed [1]; Tesla is the definition of WP:UNDUE WEIGHT. He was discovered by the New Age movement in the 60s and is a cult figure now [2]. Due to an echo chamber of hundreds of WP:FRINGE WP:PSEUDOSCIENCE websites [3] [4], [5], that promote fake science, millions of fanboys worldwide believe he invented radar [6], x-rays [7], the laser [8], the transistor [9], the fluorescent light [10], radio [11], particle beam weapons [12], and long distance wireless power [13]. In these fantasies the reason he didn't get credit is the inventions were stolen from him by [(choose one): the Government, J. Pierpont Morgan, Big Corporations, the Nazis, the Russians, Aliens]. Of course, he didn't actually invent any of these things [14] [15]. I think the article needs a section on his current cult status, debunking the many myths about his work which are so widely circulated and believed today. --ChetvornoTALK 01:08, 13 April 2019 (UTC)
@Chetvorno: Thanks anyway.

Spoken Article[edit]

I see that there is a request for this article to be read out loud. The request has been there for a long time but hasn't been put on the official article yet. Why is this? -user:Year1888 May 15, 2019, 11:04 (UTC)

Simply because no volunteer has done it yet. If you would like to do it I think the instructions are at Wikipedia:WikiProject Spoken Wikipedia. Cheers. -- Begoon 09:32, 23 May 2019 (UTC)

Tesla's nationality[edit]

It is not sure if Tesla was a Croat or a Serb. Pizzasuperman (talk) 08:42, 23 May 2019 (UTC)

See Talk:Nikola Tesla/Nationality and ethnicity, and if you have anything to add to those discussions that would be the place. Thanks. -- Begoon 09:28, 23 May 2019 (UTC)
