The Cult of Nikola Tesla

The name of Nikola Tesla is associated with crazy conspiracy claims that have nothing to do with his real work.

Nikola Tesla, aged 37, 1893

No personality in the history of science has been pushed further into the realm of mythology than the Serbian-American electrical engineer Nikola Tesla. He is, without a doubt, one of the true giants in the history of electromagnetic theory. As an inventor he was as prolific as they come, with approximately 300 patents having been discovered in at least 26 countries, but many more inventions as well that stayed within his lab and were never patented. As remarkable as were his talents was his personality: private, eccentric, possessed of extraordinary memory and bizarre habits, and with a headlong descent into mental illness during his later years. Tesla’s unparalleled combination of genius and aberrance have turned him into one of the seminal cult figures of the day. As such, at least as much fiction as fact have swirled around popular accounts of his life, and devotees of conspiracy theories and alternative science hypotheses have hijacked his name more than that of any other figure. Today we’re going to try and separate that fiction from the fact.

First, a very brief outline of his life; but in order to put it in the proper perspective, we have to first clear up a popular misconception. Tesla did not invent alternating current, which is what he’s best remembered for. AC had been around for a quarter century before he was born, which was in 1856 in what’s now Croatia. While Tesla was a young man working as a telephone engineer, other men around Europe were already developing AC transformers and setting up experimental power transmission grids to send alternating current over long distances. Tesla’s greatest early development was in his mind: a rotary magnetic field, which would make possible an electric induction motor that could run directly from AC, unlike all existing electric motors, which were DC. At the time, AC had to be converted to DC to run a motor, at a loss of efficiency. Induction motors had been conceived before his birth, but none had ever been built. Tesla built a working prototype, but only two years after another inventor, Galileo Ferraris, had also independently conceived the rotary magnetic field and built his own working prototype. Rightfully fearing that his own obscurity as a telephone engineer was hampering his efforts as an inventor, Tesla arranged to move to the United States. He did so in 1884, getting his famously ill-fated and short-lived job in Thomas Edison’s laboratory.

The tycoon George Westinghouse, who understood the potential of AC and induction motors and was actively seeking them, gratefully purchased some of Tesla’s patents as soon as he learned about them. Royalties from Westinghouse fattened Tesla’s wallet, and a number of highly public projects on which they collaborated made him a celebrity, including the 1893 illumination of the World’s Fair with alternating current, and the subsequent creation of the Niagara Falls power plant. It was as a result of this windfall that Tesla set up his own laboratories and created his most intriguing inventions. Let’s run through a list of some of the seemingly magical feats attributed to Tesla, beginning with . . .

Nikola Tesla Wasn’t God And Thomas Edison Wasn’t The Devil

Alex KnappBy Alex Knapp via Forbes

“It takes a thousand men to invent a telegraph, or a steam engine, or a phonograph, or a photograph, or a telephone or any other important thing—and the last man gets the credit and we forget the others. He added his little mite — that is all he did. These object lessons should teach us that ninety-nine parts of all things that proceed from the intellect are plagiarisms, pure and simple; and the lesson ought to make us modest. But nothing can do that.” – Mark Twain

The Oatmeal is a fantastic comic that I recommend that you make a habit of reading. However, even the greatest can go astray, and I’m pained to admit that The Oatmeal has done so regarding someone I regard very highly, and that’s Nikola Tesla. Alas, The Oatmeal has fallen prey to Tesla idolatry, confusing his genius for godhood and of course, setting up the now all-too-common ‘Edison as Tesla’s arch-villain’ narrative.
There are quite a few errors and misconceptions about both Tesla and Edison in this comic. But they’re errors that I’ve seen before and they are often repeated, so it’s worth the time, I think, to address some of the big ones.

Tesla Didn’t Invent Alternating Current And He Wasn’t A Major Power In The War Of The Currents

Let’s start with the first thing the comic says: “In a time when the majority of the world was still lit by candle power, an electrical system known as alternating current and to this day is what powers every home on the planet. Who do we have to thank for this invention that ushered humanity into a second industrial revolution? Nikola Tesla.”
This is just wrong. Alternating current was developed in principle by Michael Faraday and in practice by Hippolyte Pixii in the early 19th century. Practical devices employing AC in the medical world were developed before Tesla was even born. Contemporaries of Tesla working for George Westinghouse developed practical methods of distributing AC power from power plants before Tesla came to work for Westinghouse. Tesla himself actually studied the use of AC in college – he had an electrical engineering degree.

10 Uncomfortable Truths About Nikola Tesla

tesla_125pxBy Gregory Myers via Listverse

Nikola Tesla has become something of an Internet hero. According to legend, he was a mad genius who almost never got the credit he deserved in the money-hungry world of science. It’s easy to argue that Tesla didn’t make it further because of his eccentricities: He hated everything, suffered from severe obsessive-compulsive disorder, and might have been autistic. The truth, however, is far simpler: Many of his ideas just weren’t viable. Although many people would like to believe otherwise, Tesla was far from perfect.

10 • Alleged Eidetic Memory

Eidetic Memory_300pxIt’s often claimed that Tesla never needed to write anything down because he had either a photographic or eidetic memory. While scientists have not ruled out the claim, the researchers who have studied the phenomenon have admitted that they can’t even prove its existence, although others have pointed out flaws in their methodologies.

As a brilliant scientist and inventor, it’s quite possible that Tesla had excellent visual memory, but it was never tested. It’s certainly not true that he never needed to write anything down—Tesla kept copious notes on his inventions and ideas, many of which have survived to this day. Scientists were thrilled by the possibilities they might contain, but upon examination, these notebooks were found to be highly speculative and contain no useful scientific knowledge.

9 • Irresponsibility With Money

Irresponsibility With Money_300pxMany people claim that Tesla died penniless, and some go so far as to say he always was. This is decried as a great injustice against such a brilliant mind. The truth, much like the man himself, is a little more complicated. There is some evidence that he could have made more money if his patents had been secured better or he had not been exploited by people like Thomas Edison. Tesla never cared much for the business aspect of his work, though, and even if he had made a fortune, he likely would have blown it.

Tesla had a reputation for hemorrhaging money. He lived in fancy hotels and sunk the rest of his money into increasingly ambitious—and expensive—projects. He had a history of borrowing money from friends and getting evicted from those hotels. He would sometimes even leave some of his notebooks behind as collateral for the debt when he moved out.

Tesla once commented on his poverty when the city tried to force him to pay a tax bill, admitting that he had no money and “scores” of other debts he owed. He explained that he had been living on credit at the Waldorf for several years. He had plenty of opportunities to pay off his debts and keep his patents from lapsing, but instead, he maintained his lavish lifestyle until the day he died.

8 • Wild Claims

Wild Claims_300pxThanks to the Tesla revival, every absurd claim he made to newspapers back in the day is now being repeated as fact. The truth is that Tesla made many claims so far out of left field that they would destroy a scientist’s credibility even today, often with no evidence or results to back them up. But if Tesla was crazy, he was crazy like a fox. Oftentimes, his claims were reported shortly before the historical experiments of other scientists.

For example, when Marconi was gearing up for some important radio signal tests, Tesla told the media that he had already received radio transmissions that he believed were from Mars. With his technology, he claimed, we would soon be able to communicate with other planets almost instantaneously. Other projects he claimed to be working on included a torpedo that could be recalled even after being fired and a powerful death ray.

As bizarre as these claims sounded, they gave the impression that Tesla was light-years ahead of everyone else. But if the general public was impressed, the scientific community was decidedly not, regarding Tesla as being mostly full of hot air. While this is an overreaction—Tesla certainly did contribute to our body of scientific knowledge—the plausibility of many of Tesla’s inventions is greatly exaggerated.

7 • Strange Visions

Visions_300pxTesla’s tall tales weren’t confined to his inventions or supposed interactions with Martians. He also believed that he received a variety of important visions. The first occurred when he was walking in the park with a friend after suffering a nervous breakdown due to his constant lack of sleep.

According to Tesla, he had a vision of the entire model for his AC motor and started drawing it in the dirt. Considering that he had already stated that he had been thinking about the idea for about six years, he probably wasn’t being entirely truthful.

His second “vision” occurred much later in life, involving his beloved pigeons. He claimed that he was alone in his hotel room one night when a white pigeon for whom he harbored particularly great affection came to see him. He was then suddenly blinded by two powerful beams of light that communicated to him that he had finished all of his life’s work and would die soon.

6 • Insomnia And Addiction To Work

Insomnia_300pxTesla’s visions could probably be more reasonably attributed to his lack of sleep than any mystical properties. He was known to be a workaholic, to the point that any kind of rest was inconceivable. He claimed that he went to bed at 5:00 AM and rose only five hours later, and only two of those hours were spent sleeping. Once a year, he indulged himself and actually slept all five hours. He never stopped thinking about his work, even when he was snoozing.

There’s no doubt that Tesla’s insomnia had a profound impact on his physical and psychological health for his entire life, but it’s likely that its extent was another of his exaggerations. Humans simply aren’t capable of maintaining such a lack of sleep and remaining alive. However, it is possible Tesla had simply deluded himself. The hotel employees who attended his room said they often found Tesla standing silently, apparently awake but totally unaware of his surroundings. It’s likely that he slept more than he realized, falling into these nap-like trances as a natural reaction to that level of sleep deprivation.

Where Is the Science in Electronic Voice Phenomena?

It is hard to turn on the television today without coming across a program about ghosts and the paranormal. These shows might shine an entertaining light on the unknown, but they are often more about their cast of characters and investigators than the science of parapsychology.

Since the 1920s, when Thomas Edison hinted that he might have attempted to build a “ghost machine” to communicate with the dead, some have tried to apply a scientific method to proving the existence of life after death. So far this has been unsuccessful, and to this day every group of investigators, both amateur and professional, has their own set of protocols as to what is or is not considered paranormal (see Sharon Hill’s “Amateur Paranormal Research and Investigation Groups Doing ‘Sciencey’ Things,” SI, March/April 2012).

With no universally accepted methods of investigating the paranormal, the beliefs of investigators can greatly influence the outcomes of their own investigations. Some investigators believe removing objects from a location will end a possible haunting. Others use objects to capture spirits, and psychic investigators believe spirits can be blessed or cast away. None of these methods have been scientifically proven, yet every investigator claims that the method they use is successful.

In pursuit of scientifically verifiable evidence, tools of all types have been employed. Many theories about detecting paranormal activity have been tested using everything from dowsing rods to Geiger counters. While the evidence they provide is scientifically debated, some tools such as audio recorders have become popular mainstays of the paranormal investigator.

soundwave-175x150The art of recording EVPs, or electronic voice phenomena, is one of the most widely accepted methods of collecting evidence. Originally, a portable tape recorder was used to record an investigator asking a series of questions and waiting for responses in the silence following each question. After the EVP session, the tape was played back and investigators listened for intelligent and relevant responses caught on the tape but not audible to the ear at the time. The theory is that spirits do not have enough energy to create sounds audible to the human ear but can leave impressions on the tape.
