Tesla: Man Out of Time by Margaret Cheney


AltaVista, dematerialisation, fudge factor, invention of radio, luminiferous ether, Menlo Park

But, by a few years, it precedes Marconi’s inventions and practical demonstrations of wireless telegraphy.”2 Figures 165 and 185, referred to in the United States Supreme Court case, are from Tesla’s 1893 lecture and are frequently cited as evidence supporting his claim of invention of radio. Anderson points out that some have confused the argument with respect to the principles of transmission and reception of radio signals with the matter of transmitting voice—an important improvement made practical by DeForest’s Audion, or triode vacuum tube. “In a discussion of priority in the invention of radio, one must be very specific about definitions,” he writes. “In the . . . case of the Marconi Wireless Telegraph Company of America vs. United States (which was decided June 21, 1943, against the Marconi Company and striking down the fundamental Marconi patent), the following definition evolved out of the exhaustive depositions taken from many technical experts in the fields of radio and the physical sciences: “‘A radio communication system requires two tuned circuits each at the transmitter and receiver, all four tuned to the same frequency.’

The real binding up and deprovincial-ization of the planet requires a technology that communicates much faster than horse or sailing ship, that conveys information all over the world, and that is cheap enough to be available, at least occasionally, to the average person. Such a technology began with the invention of the telegraph and the laying of submarine cables; was greatly expanded by the invention of the telephone, using the same cables; and then enormously proliferated with the invention of radio, television, and satellite communications technology. Today we communicate—routinely, casually, with hardly ever a second thought—at the speed of light. From the speed of horse or sailing ship to the speed of light is an improvement by a factor of almost a hundred million. For fundamental reasons at the heart of the way the world works, codified in Einstein's special theory of relativity, we know that there is no way we can send information faster than light.

Extraterrestrial Civilizations by Isaac Asimov

Radio waves could easily be produced in coherent fashion, so that a tight beam could go long distances, and could easily be modified to carry messages. For all these reasons radio waves were clearly ideal for longrange communication, and that, too, without the wires that telegraphs and cables required. The first to make practical use of radio waves in this way was the Italian electrical engineer Guglielmo Marconi (1874–1937). In 1901, he sent a radio-wave signal across the Atlantic Ocean, a feat generally recognized as the invention of radio. From that day on, with further improvements and refinements, radio became a more and more important means of communication. It was clear to many people that any technological civilization would surely make use of radio communication in preference to anything else. Therefore, when the planet Mars made a closer than usual approach to Earth in 1924, there was some attempt to listen for radio signals from the presumed civilization that had built its canals.

Climbing Mount Improbable by Richard Dawkins, Lalla Ward

But it is an argument against intelligent, technically sophisticated life being spaced densely enough to be within easy radio range of other islands of life. If life when it starts has anything other than a low probability of giving rise to intelligent life, we might take this as evidence that life itself is rare. An alternative conclusion to this chain of reasoning is the bleak proposal that intelligent life may arise quite frequently, but typically only a short time elapses between the invention of radio and technological self-destruction. Life may be common in the universe, but we are also at liberty to speculate that it is exceedingly rare. It therefore follows that the kind of event we are seeking, when we speculate about the origin of life, could be a very very improbable event: not the kind of event that we can expect to duplicate in the laboratory and not the kind of event that a chemist will deem ‘plausible’.

DURING THE 1890s, a Serbian immigrant to America, Nikola Tesla, and an Italian, Guglielmo Marconi, each patented devices capable of sending wireless signals. In 1897, Tesla demonstrated sending ship-to-shore pulses across bodies of water in New York, even as Marconi was doing the same among various British isles—and, in 1901, across the Atlantic. Eventually they sued each other over the claim, and the royalties, to the invention of radio. No matter who was right, by then transmission across seas and continents was routine. And beyond: Electromagnetic radio waves—waves much longer than poisonous gamma radiation or ultraviolet sunlight—emanate at the speed of light in an expanding sphere. As they move outward, their intensity drops by a factor of one over the distance squared, meaning that at 100 million miles from Earth, the signal strength is one-fourth what it was at 50 million miles.

Others, including Norman Cousins, John Kenneth Galbraith, Marshall McLuhan, Archibald MacLeish, and Victor Papanek, would follow Packard’s lead in pointing out how the media create artificia needs within vulnerable consumers.The sheer volume of print Americans have devoted to this topic since 1927 demonstrates that obsolescence has become a touchstone of the American consciousness. The book you have in your hand is a collection of stories that emerged during my search for obsolescence in uniquely American events: the invention of packaging, advertising, and branding; the rivalry between Ford and GM; “death dating”; the invention of radio, television, and transistors; the war and the postwar competition with Japan; rock and roll, the British Invasion,and male fashions; universal home ownership; calculators, integrated circuits, and PCs; the space race, tailfins and TelStar; and the looming crisis of e-waste. The theory and practice of obsolescence play a central role in each of these American milestones. At each juncture, vested interests struggled and competed to achieve repetitive consumption through obsolescence, in its many forms and combinations.

Different crops prefer particular conditions of tilth; wheat, for example, likes a fairly coarse seedbed, with clods about the size of a child’s fist, whereas barley prefers a much finer tilth. Lighter harrowing is applied after sowing to cover the seeds, and can also be used between cultivated rows to tear up weeds. Once an appropriate tilth has been prepared, the next step is to put seeds into the ground. The original meaning of “broadcast”—coined centuries before the invention of radio or TV—is scattering seeds far and wide, tossing them from a sack as you walk back and forth across the field. You can distribute seeds relatively quickly this way, but you have little control over their exact placement, which makes weeding later difficult. But again, with a little bit of ingenuity you can improve this process immeasurably. A seed drill is a mechanical seed sower. At its simplest, a cart has a hopper full of seed on top, and a chain of gears driven by one of its wheels that slowly turns a paddle at the bottom of the hopper chute to release a single seed at regular intervals.

Many of the motivations and flows within the political dialog over the nature of money still welled up from local and particular regional influences. Yet the U.S. monetary system was an unresolved national question in large measure because the nation remained so dependent upon foreign capital flows. More, the ebb and flow of financial markets was slowly becoming a daily political referendum on the job done by Washington regarding the economy in general, an influence that would be made acute with the invention of radio, television, and eventually the internet over the next century. The public’s concern regarding the adequacy of the money supply in the first decade of the twentieth century is all the more ironic since it was growing at a pretty brisk pace compared with the nation’s population, which was at about 76 million at the turn of the century and reached 97 million by 1913. This increase represented between 1.5 and 2 percent growth annually.

One observer at the time, apparently oblivious to the economic forces of global capitalism, mused that airplanes opened up “the realm of absolute liberty; no tracks, no franchises, no need of thousands of employees to add to the cost,” while in 1915 the editor of Flying magazine—the Wired of its day—enthusiastically proclaimed that the First World War had to be “the last great war in history,” because “in less than another decade,” the airplane would have eliminated the factors responsible for wars and ushered in a “new period in human relations” (apparently, Adolf Hitler was not a subscriber to Flying). As much as one could speak of utopian airplane-centrism of the 1910s, this was it. But it was the invention of radio that produced the greatest number of unfulfilled expectations. Its pioneers did their share to overhype the democratization potential of their invention. Guglielmo Marconi, one of the fathers of this revolutionary technology, believed that “the coming of the wireless era will make war impossible, because it will make war ridiculous.” Gerald Swope, president of General Electric Company, one of the biggest commercial backers of radio at the time, was equally upbeat in 1921, hailing the technology as “a means for general and perpetual peace on earth.”

Because, you see, now like then, the game of patenting and intellectual monopoly is not all that democratic and open to the little guys as Ms. Khan’s recent and altogether interesting book would like us to believe. So, it is the case that Marconi, supported by the likes of Edison and Carnegie, kept hammering the U.S. Patent Office until, in 1904, it reversed course and gave Marconi a patent for the invention of radio: “The reasons for this have never been fully explained, but the powerful financial backing for Marconi in the United States suggests one possible explanation.”43 We will spare you the sad story of Nikola Tesla’s hapless fight against Marconi, you can figure that out by yourself.

He was also afflicted with an obsessive-compulsive disorder; he refused to shake hands, he would feel a need to read all the books written by any author he encountered, and he had a peculiar devotion to the number three and to any other number divisible by it. Though the Serbian-born inventor Nikola Tesla, clever, fragile, and an eccentric showman, was until recently widely overlooked, it is now generally accepted that he made vast contributions to the development of alternating electrical current and the invention of radio, long before Marconi. He has lately won legions of new admirers, mostly young, who see him as a forgotten hero of American science. Nikola Tesla was, in short, the classic exemplar of the mad scientist, and the fact that he made dangerously interesting inventions by the score resonates still with today’s imaginative fans of the far-fetched. He made devices like the Tesla coil, a step-up transformer that could raise current into the tens of thousands of volts and then generate Niagaras of gigantic electrical sparks.

During periods of perturbation, more of the ways in which society organizes itself are up for grabs; more can be renegotiated, as the various other components of human stability adjust to the changes. To borrow Stephen Jay Gould's term from evolutionary theory, human societies exist in a series of punctuated equilibria. The periods of disequilibrium are not necessarily long. A mere twenty-five years passed between the invention of radio and its adaptation to the mass-media model. A similar period passed between the introduction of telephony and its adoption of the monopoly utility form that enabled only one-to-one limited communications. In each of these periods, various paths could have been taken. Radio showed us even within the past century how, in some societies, different paths were in fact taken and then sustained over decades.

Its gradual departure as a concept marked an end to the physical picture on which Faraday and Maxwell alike had relied to conceive their theories. After Maxwell, mechanical explanations of electric phenomena no longer sufficed, yet theoretical knowledge of their nature remained far from complete.64 Stupendous discoveries and developments flowed from Maxwell’s concepts. They led most directly to the invention of radio and more abstractly to Albert Einstein’s theory of relativity. At the time, however, many physicists shrank from Maxwell’s argument despite its solid grounding in mathematics. They could not accept the notion that insulators, which confined electric currents within prescribed paths, could also be the seat of electric action. A curious irony arose. Faraday struggled for acceptance because he could not root his theories derived from experiments in mathematics.
