The Curious Case of the N-Rays, a Dead End for All Times
I GOT A CALL FROM a friend who lives down the street, Dr. James Cooke, an anesthesiologist with Emory Hospital. Cooke grew up in Berrien Springs, Michigan, along with his friend, Gregory Stemm, founder and CEO of Odyssey Marine Exploration. Stemm needed a favor.
Odyssey Marine Exploration was in the habit of finding old shipwrecks that had gone down carrying a lot of gold, and Stemm was always on the lookout for new technology that claims to find precious metal at a distance, buried or under a lot of water. A fellow from Florida, to whom I will refer as Randy, had approached him with a new type of gold-finder instrument. Would I take a look at what he claims and make a preliminary evaluation? Be glad to. Send him up to Atlanta.
Randy arrived, not with his device, but with a photograph of it and some maps showing found booty. He looked like a walking American Legion post, decked out in a jacket and a hat crowded with Vietnam War patches. We asked him to explain his device. It looked like a metal box, about a cubic foot, with a parabolic dish antenna on the front, some unlabeled knobs and switches, and a meter on the back. Randy explained that he was in the navy in the Vietnam conflict, working the radar set on a ship, when he noticed certain signals when the antenna was aimed at far-off metal objects. Using his knowledge of military radar, he had perfected his gold-finder using technology that could detect the special, undocumented radiation that is emitted by all matter, concentrating on the specific characteristics of radiations given off by gold and silver.
His description of how his instrument worked was vague and mysterious. I concluded that either his device was unprotected by a patent and he feared theft of the design, or that he had no idea how it worked. Claims of performance measures for it ranged all over the map, depending on how the question was worded, but I got the impression that this particular model gold-finder could locate an 80-ton block of pure gold at a distance of 40 miles. I paused to wonder how he had tested this capability.
My immediate impression of the device was not positive. For one thing, the probe in the center of the antenna dish was way too long, far outside the focal point of his parabola, but my opinion was clinched when he described its operation. Not just anyone could use the instrument correctly to find gold or silver. In fact, he was the only one who knew how to turn the knobs and read the subtle movements of the meter, and it was impossible to explain it to anyone else. He had, however, practiced with his children reading the dial, and he was confident that they would soon be able to use the instrument effectively.
That was all I needed to hear. He was describing something that in experimental science is called the Hieronymus Effect. This term is used to condemn a physical measurement in which a certain sensitivity of a human being is an essential component of the instrumentation. The problem with using the Hieronymus Effect is that no two people are exactly alike, and that can result in different outcomes of the same measurement. This complicates the problem of duplicating an experiment and compromises the integrity of results. The dependence on a Hieronymus Effect is therefore avoided in any scientific experiment or engineered data collection effort. Your measurement or detection must rely on the objectivity of physical equipment and not on the wishful impressions of a person.6
Thomas Galen Hieronymus, born in 1895, worked for twenty-five years as an engineer at the Municipal Power Company in Kansas City, Missouri. Always looking beyond the daily grind at the power company, Hieronymus tinkered constantly with the frontiers of electronics and physics in his home laboratory. He had a theory that life on Earth, particularly chlorophyll plant life, depended on more than sunlight for the growth process. He postulated that there is another, unknown type of radiation from the sun that does not propagate by electromagnetism. He described it as “eloptic” energy, and in the 1930s he devised several experiments proving its existence.
His setups were orderly and scientific. In a totally dark room, several germinating pots were arrayed on a tabletop, each containing an oat seed and a small amount of dampened potting soil. On the bottom of each pot was a metal plate, connected by a copper wire to a common cold-water pipe. Atop each pot was a metal screen, and all but one of these screens, which would be the control specimen, were electrically connected to metal plates outside the lab and on trays facing the Sun. The plates were of varying sizes, and the results of growing oat plants in the dark seemed to confirm that a previously undiscovered form of solar radiation was being conducted to the plants and causing them to thrive. All plants germinated, but only the ones connected to outside radiation collectors (metal plates) survived to turn green. The specimens connected to the larger plates actually seemed scorched, while those on the smallest plates were only weakly green.
Encouraged by his experimental results, Hieronymus further postulated that all matter emits this energy, and that, on an atomic level, its wavelength depends on the atomic weight of the nuclide that is emitting. He quit his day job at the power company and devoted the rest of his life to investigating his discovered form of radiation and developing practical instrumentation to exploit its properties.
His most famous invention, the Hieronymus Machine, was capable of sorting the elementary constituents in a sample of anything and indicating how much of which elements made up the specimen. This was doing what a mass spectrometer does, only without pulling a hard vacuum. The user would place a sample, such as an airplane rivet, onto a flat, spiral-coil of magnet wire, connected back to the instrument, and stroke his or her fingertips on a copper plate that is covered with insulating lacquer. By turning a knob slowly, the user would find places along the 60-degree arc of the knob at which the plate would become rough or sticky to the finger touch. These incidents were noted as degrees of deflection, and each could then be mapped into an atomic weight using a simple chart.7 The rivet would then analyze as being mostly aluminum, with some magnesium and silicon traces.
This analysis was determined using a fixed, triangular glass prism to spread the radiation spectrum being emitted from the specimen into a 60-degree span. The radiation was conducted from the object being analyzed into the machine using wires, just as it had been in Hieronymus’s plant-growth experiments. Inside the box, the transported radiation would escape from a small, metal electrode; be collimated by a short, narrow tunnel; and hit the prism base at a 30-degree angle, where it would be bent to an extent dependent on the wavelength of the radiation. The radiation would then be reacquired by an identical electrode connected to a swing-arm attached to the knob. The weak radiation signal would then be amplified millions of times using a three-stage audio amplifier and ultimately connected to the copper touch-plate.
T. Galen Hieronymus applied for a patent of his device, “Detection of Emanations from Materials and Measurement of the Volumes Thereof,” on October 23, 1946.8 The patent was awarded on September 27, 1949, and the Hieronymus Machine went into limited production. His best seller was the Eloptic Medical Analyzer, which could both diagnose and treat any medical condition in crops and farm animals.
By 1954, Hieronymus was at the top of his game. His field of science now had a name, psionics, and he had branched out into building a newer device with more signal amplification, called the “pathoclast.” He was now living in Hollywood, Florida, had been given an honorary PhD in physics, and had demonstrated his device to Dr. Arthur Compton, chancellor of Washington University and discoverer of the Compton Effect. The Air Force wanted to talk to him about detecting human presence on the ground from a high-altitude airplane.9
At this zenith of psionics research, he got a call from John W. Campbell Jr., the influential and intellectually overwhelming editor of the magazine Astounding Science-Fiction. Astounding was widely read among the scientists and technologists populating the national laboratories, and Campbell, a self-proclaimed nuclear physicist, was beginning to lose interest in his favorite pseudoscience, L. Ron Hubbard’s dianetics. Dianetics had started out as Hubbard’s alternate answer to psychiatry but had morphed into a religion called Scientology. Religion did not interest Campbell, but psionics sounded exotic and weird, just the way he liked it. He quickly broke down any resistance Hieronymus had to revealing everything, and within days was building psionics machines in his home laboratory in Mountainside, New Jersey.
At first skeptical, Campbell with his own tests became convinced of the legitimacy of the Hieronymus machine concept. He began a new campaign to push Hieronymus and his machine in an editorial in Astounding, June 1956, “Psionic Machine—Type One.”
This was superb advertising for psionics and the Hieronymus Machine until Campbell left the rails. During his extensive program of testing and verification of the Hieronymus Machine, Campbell noticed that one did not have to be touching an actual machine to exploit its principles of operation. In fact, a schematic diagram of the machine, drawn with a pencil on a piece of paper, worked just as well. He could lay a rock over the drawn depiction of the sensing coil, erase the picture of an open switch on the amplifier schematic and redraw it as a closed switch, then rub the picture of the metal pad with fingertips. When he had drawn the receiving electrode at the proper angle on the schematic, he could detect the composition of the mineral by feel. The paper became sticky. After a while, the thing would quit working, and he would have to erase the diagram of the now-dead battery and redraw it.
This discovery was written up in the magazine, and it did not go down well in the scientific community, which had been quietly discounting the claims as wishful thinking. Campbell enthusiastically interpreted this finding as proof that the Hieronymus Machine worked by means of extrasensory perception, or ESP. At that point, in the early 1960s, the Hieronymus Machine and John W. Campbell Jr. were effectively torpedoed and eventually sank out of sight. The entire concept of putting a human being’s sensory perception somewhere in line in a data measurement was solidly confirmed as a dead end. Eloptic radiation does not exist, and any research scientist who would bother to test a psionics machine would find its action driven by psychology and not physics. T. Galen Hieronymus died in 1988, and his machine went with him.
Such pseudoscience was understandable coming from a radar technician, a science fiction magazine editor, and even from an electrical engineer, especially at a time when parapsychology, chiropractic, unidentified flying objects, hypnosis, and searches for Noah’s Ark were seriously pursued and even funded. One can get caught up in the pursuit of new knowledge and lose track of reality, clinging only to positive evidence and neglecting any negative findings. You might expect it less from a professional scientist, but you might be wrong.
The Hieronymus Effect had its most profound incident in 1903 at the Nancy-Université, in Nancy, France. It caught Prosper-René Blondlot, professor of physics. It would go down in history as the “N-rays illusion.”
In 1903, the atomic nucleus had yet to be discovered, yet what would become known as nuclear physics was crashing ahead at full speed, and discoveries were being documented on a monthly basis. Still stinging from the attention-grabbing discovery of X-rays in Germany back in 1895, Professor Blondlot and his assistants were actively striving to find another particle of radiation before they were all gone. Paul Villard, after all, had discovered the gamma ray at École Normale Supérieure rue d’Ulm in Paris just three years prior. Blondlot considered the École a good place to train high school teachers, and the major finding coming from it was something of an embarrassment to the public university system. Blondlot was determined to bring things back into balance by making a gamma-ray-eclipsing discovery with unique strangeness and novelty at his beloved Nancy University.
Blondlot was born in Nancy in 1849, the son of the professor of toxicology at the university, Nicolas Blondlot, MD. He received his doctorate in physics at the Sorbonne in 1881 and joined the faculty at Nancy the following year. He thrived in his element as a professor, winning the Gaston Plante Prize for research in 1893 and the La Caze Prize in 1899. He had successfully measured the extremely rapid response speed of a Kerr cell under electrical excitation using an ingeniously modified rotating-mirror apparatus from Léon Foucault’s speed-of-light measurements.10 After that, he measured the speed of radio waves, confirming an important prediction by James Clerk Maxwell. By 1903, Blondlot was on a roll.
On February 2, he submitted a paper to the French Academy of Science, “On the Polarization of X-Rays.” Blondlot was generating X-rays using a simple vacuum tube driven by a Ruhmkorff high-voltage apparatus. The Ruhmkorff transformer converted the six volts from a battery into several thousand volts. The high voltage was not exactly steady, but was produced in a ragged, pulsed alternating current using a buzzer operating off the iron core of the transformer.11 On the positive-going section of the high-voltage waveform, or about half the time, electrons would stream off the cathode of the tube, run a couple of inches through the vacuum, and crash against the metal anode plate, canted at 45 degrees and pointing the resultant X-rays through the side of the tube and into the room.
Blondlot had a novel idea for detecting any polarization of the X-rays, or the tendency of the electromagnetic waves to vibrate in only one direction. He took a twisted pair of heavily insulated wires and wrapped the bare ends around the feed lines from the Ruhmkorff, with one on the anode lead and one on the cathode lead. He then supported the other end of the wires in front of the vacuum tube, with the bare ends pointing at each other and separated by “a very small distance,” making a spark gap. He reasoned that the electromagnetic oscillations of the X-rays would interact with the spark gap, and furthermore the extent of interaction due to polarization, whatever that might be, would be dependent on the orientation of the long axis of the gap.
Blondlot found what he was looking for. When he twisted the gap, which was making a semicontinuous, sputtering high-voltage spark, the visible brightness of the spark changed, indicating that the X-ray was indeed affecting the gap and that it was orientation dependent. Moreover, using the spark-gap detector, he could observe a twist in the polarization of the X-ray using an interstitial crystal of quartz or lump sugar. His X-rays therefore behaved like visible light.
Excited by these fascinating results, Blondlot continued experimenting, looking for other ways that X-rays might behave the same way as visible light. To preclude any cross-contamination, he shielded the cathode-ray tube with metal foil to block out any visible-light fluorescence produced by electrons hitting the glass. Using the spark-gap detector and his eyesight to judge the spark intensity in a darkened room, he found evidence of elliptical polarizations using thin sheets of mica. With this finding, he leapt to the next logical step and put a glass lens in the X-ray path. He was astonished to find a perfectly focused, inverted image of the tube’s cathode, suspended in space in front of the lens. He scanned across the invisible image using his spark-gap X-ray detector, finding the sharp edges of the image at the predictable focal plane of the lens.
Coming down off the euphoria, Blondlot realized that there were only two problems with these observations. X-rays don’t really brighten sparks, and X-rays do not focus using a glass lens. In fact, he believed he was looking at a new, previously undiscovered form of radiation coming out of the X-ray tube. These rays are plane polarized coming out of the tube, can be circularly polarized, and can be reflected, refracted, and diffused, but they do not interact with photographic media, nor do they make anything fluoresce.
His next, ground-trembling paper was “On a New Species of Light,” submitted on March 23, 1903, in which he announced his discovery, soon to be named “N-rays” for his university. He concluded the paper saying:
At first I had attributed to Roentgen rays the polarization which in reality belongs to the new rays, a confusion which it was impossible to avoid before having observed the refraction, and it was only after making this observation that I could with certainty conclude that I was not dealing with Roentgen rays, but with a new species of light.
So launched an accelerated effort to find the peculiar characteristics of this new type of radiation. Blondlot and his assistants, seeing a future graced with research prizes and possibly, if they dared hope, a most coveted Nobel Prize in physics, applied themselves with vigor and resolve.
Blondlot worked to identify all possible sources of N-rays. He made a chart showing which materials would conduct N-rays and which would stop them. He measured the index of refraction in different circumstances, and discovered three subspecies of N-rays. New data piled up, and on May 11, 1903, he submitted another paper, “On the Existence, in the Rays Emitted by an Auer Burner, of Radiations which Traverse Metals, Wood, etc.”12 Four days later, he submitted another paper, and six more by the end of the year. He could not have been getting much sleep. In the next three years Blondlot would submit twenty-six papers concerning N-rays and eventually publish a book. His fellow research physicists, 120 of them, mostly of Gallic origin, would collectively publish almost three hundred notes, articles, and papers on the subject.13 It required fifty-nine pages to briefly list the discoveries concerning N-rays.
The found properties were peculiar, but so were characteristics of other contemporary discoveries. N-rays would not cause fluorescence, but they would enhance a previously established fluorescence. Aluminum, gold, platinum, silver, glass, and oak were all transparent to N-rays, but a sheet of wet cardboard would stop them cold. N-rays, to one extent or another, seemed to be emitted by just about everything, from the Sun to a Nernst lamp, with special “physiological” N-rays coming from anything alive, including human beings. N-rays were definitely not emitted by green wood or (I hope you’re sitting down) tempered steel that had been anesthetized by first soaking it in ether or chloroform.
A tempered steel file, presumably borrowed from the school shop, that had not been put to sleep, however, turned out to be an excellent source of N-rays. Using the file as a source, it was found that N-ray flux enhances human eyesight. In a dimly lit laboratory, it was hard to read the clock on the far wall and tell whether it was time to put down the instruments and go home, but Blondlot found that if he held that file up to his face the N-rays would improve his vision to the point that the hands of the clock would snap into focus and the light-gathering power of the retina would increase. The same was true of a material under stress. Hold up a seasoned wood walking stick in front of your eyes, bend it almost to the breaking point, and you could almost see without the glasses.
Back in the United States, there was a mounting sense of skepticism concerning Blondlot’s new form of radiation. Other forms of radiation, such as Hertz’s radio waves or Roentgen’s X-rays, were the result of some form of expended energy, and alpha, beta, and gamma rays were known to be generated by atomic decay, an irreversible process. If everything emitted N-rays all the time, then how long could this continue before the source was exhausted? The massive list of effects attributable to N-rays was starting to look silly.
Robert W. Wood, professor of optical physics at Johns Hopkins University in Baltimore, highly accomplished experimentalist and inventor, author of two science fiction novels, and the one who admitted to having written How to Tell the Birds from the Flowers, was in Britain attending a scientific conference when he decided that he had heard enough about N-freaking-rays. He had “wasted an entire morning” trying to duplicate at least one of Blondlot’s experiments, and had corresponded with the French scientist making sure that he hadn’t been doing it all wrong. Blondlot had been delightfully cordial and patient with him, but Wood found his body of work concerning the new radiation hard to swallow. Wood took a side trip to Nancy, France, to meet Dr. Blondlot and see for himself what was going on.
Blondlot was pleased to demonstrate all of the fundamental N-ray experiments over the course of three hours in the laboratory. First, Wood was shown a spark-gap detector with N-rays concentrated on it using a lens made of solid aluminum. The light from the spark, which is a naturally sputtering, dancing illumination source, was diffused with a piece of frosted glass. With the lights turned down, an assistant would put his hand between the source and the lens, demonstrating that the normally bright spark, enhanced by the focused beam of N-rays, would dim when his hand was in the way. Woods had to admit that he could not see this effect. To him, the spark always looked about the same, although it was randomly flickering at about 25% luminosity just due to the fact that it was a high-voltage spark. A spark tends, naturally, to heat up the air it is passing through. The hot air wants to float to the ceiling and take the spark with it, so there is a chaotic tug of war between the rising air and the need of the spark to seek the path of least resistance between the electrodes. His inability to see the difference in the brightness of the spark was attributed to a lack of sensitive eyes.
Wood suggested another way to run the experiment. “You look at the spark and tell me when my hand is in the beam.” The assistants were unable to guess correctly when he had his hand in the beam and when he had withdrawn it.14 An explanation was not offered, and they moved quickly to the next demonstration.
The lens was removed and replaced with a screen of wet cardboard having a vertical slit about 3 millimeters wide. In front of the slit was placed an aluminum prism, which would receive the 3-millimeter N-ray beam and spread it out into a spectrum. Replacing the spark gap as the detector was a piece of dry cardboard with a thin, vertical line of pre-excited, glowing phosphorescent paint drawn on it, about half a millimeter wide. The cardboard was on a track so that it could be slid past the slot with a crank-driven screw. When moved through the spread of the N-ray spectrum, the demonstrators claimed that spectral lines as fine as 0.1 millimeter wide would make obvious changes in the brightness of the phosphorescent line. When Wood asked how a bundle of rays 3.0 millimeters wide, as defined by the width of the slit, could possibly make a spectrum that could be resolved down to 0.1 millimeters, he was told that this was “one of the inexplicable and astonishing properties” of N-rays.
As he cranked the phosphor detector through the N-ray spectrum, Wood had to admit that he could not see any deviation in the brightness of the line of paint. Perhaps, he suggested, it would be easier on his unpracticed eyes if they turned off the lights? The researchers agreed, but with the lights out, Wood removed the prism and put it in his pocket. Blondlot ran the detector through its entire sweep, pointing out the characteristic spectral lines as he saw them lighting up the line of phosphorescent paint, even though there was no prism in the setup to generate a spectrum. At that exact point in time, as the detector carriage reached the end of the spectrum image, the entire N-rays phenomenon turned downward and began the long slide to oblivion.
Wood was shown the effect of holding a file up to your face and being able to see in the dark. It did not work when Wood tried it, and the experiment was easy to shoot down. Wood suggested that he should hold the file in front of an assistant’s face while he looked at the clock hands, while he surreptitiously substituted a block of wood for the piece of tempered steel. The assistant did not notice the chicanery and reported improved eyesight.
Wood immediately wrote up his discouraging, depressing experience at the University of Nancy and sent it from Brussels, Belgium, to the premier science journal in Britain, Nature, on September 22. It was published in the September 29, 1904, issue, and the word spread like the bubonic plague across Europe. In October, the same letter appeared in the French Review Scientifique and the German Physicalische Zeitschrift, and N-rays crashed slowly over the next two years.
At the end of 1904, as the N-rays controversy exploded around him, Prosper-René Blondlot was awarded the Prix Leconte, a prize given by the French Academy of Sciences recognizing important discoveries in mathematics, physics, chemistry, natural history, or medicine. It was 50,000 francs, or five times his annual salary. He continued in his post as professor of Physics for the next six years, dialing back the N-rays research but never admitting the nonexistence of his rays. He retired at age sixty-one in 1910 and lived for another twenty years in his large home at 16-18 Quai Claude le Lorrain. He wrote a new preface for the third edition of his textbook on electricity in 1927. He and the last mention of N-rays died in 1930. He was eighty-one years old. There is a street named for him in Nancy.
Robert W. Wood continued a distinguished career in optical physics, becoming a member of the Royal Society in London, winning seven awards in optics and physics, and serving as president of the American Physical Society. The ultraviolet lamp he developed for medical use is still called the “Wood’s lamp,” and the bright reflection from green plants in infrared photographs is called the Wood Effect. A crater on the far side of the Moon is named after him.
He died on August 11, 1955, at age eighty-seven.
N-rays are often cited as an isolated example of pseudoscience, and yet mysterious rays with similar characteristics would show up from time to time in the even more enlightened later twentieth century. N-rays were not even new in 1903. The same phenomenon had turned up in 1850, having been discovered by Baron von Reichenbach in London and revealed in his treatise “Researches on Magnetism, Electricity, Heat, Light, Crystallization, and Chemical Attraction in their Relations to the Vital Force.” Before that, Franz Mesmer in Vienna had detailed the same rays in 1779 in his “Memoire on the Discovery of Animal-Magnetism.” Every time they pop up, N-rays or the equivalent are eventually knocked down as scientific delusions, if not outright fraud.
Physics is a wide field of study and discovery, trying to cover all of reality. One branch of this science deals with the invisibly small “hard nut,” the nucleus, at the center of the atom, the fundamental unit of condensed matter. Nuclear physics stands atop two dissimilar, conflicting theory sets working at opposite ends of the largeness spectrum—quantum mechanics for the imperceptibly small and general relativity for the astronomically big. Quantum mechanics predicts that the mass of things on the atomic scale can be diminished just by rearranging the component parts, and relativity predicts that this change will manifest itself as a surprisingly large energy release. There is nothing intuitively obvious about this phenomenon or anything else about nuclear physics, and this inherent strangeness keeps it out on the edge, dangling over the precipice and always in danger of falling into the infinitely deep pit of the not possible. The specter of pseudoscience always hangs close.
N-rays seem impossible, at least in retrospect, but what about nuclear physics would not seem odd? The field covers everything from turning platinum into gold to the quantum entanglement of photons. So, try to stay in touch with what you consider to be reality in the following chapters, as I step you through some atomic adventures. There are inevitabilities and things that never should have happened. There are things to fear and things that should cause no alarm. There are monuments to fallibility and tiny markers for the truth. I hope to convince you that while nuclear science can be unbelievable or even dreadful, it is never a boring topic of study, conversation, or even reading.

6But science is flexible. Alessandro Volta was a professor of experimental physics at the University of Pavia, Italy, in 1800, when he invented the electric battery. The first voltmeter, used to determine that electricity was indeed being produced by the new device, was Volta’s tongue. He would place the two wires, anode and cathode connections, against the tip of his taster and feel the burn. This important experiment, by definition, employed the Hieronymus effect. Some people could definitely taste the “metallic” flavor of electricity, and, over a spectrum of response sensitivity, some could not. How Volta thought to stick the wires in his mouth is not written down.
7I am writing this description from T. G. Hieronymus’s literal description of his device. I think that he meant to say “atomic number.” Given only the atomic weight, one could derive only a vague idea of what the element is. Finding, for example, an atomic weight of 14, the specimen could be either oxygen-14 or carbon-14. An atomic number, the number of protons in an element’s nucleus, corresponds only to a specific element.
8The title of this patent, no. 2,482,773, is misleading. Nowhere in the patent does this device claim to measure the volume of anything. It is supposed to measure the element composition of materials.
9Hieronymus gladly stepped up to this challenge, but instead of mounting his machine in the downward-looking bombsight window of a high-altitude plane, he instead requested photographs of the ground where soldiers were hidden. The Air Force complied, Hieronymus scanned the pictures with a psionics device, and he found evidence of people all over the photographs. When told that people were only in a few locations, Hieronymus explained his analysis saying that the soldiers had obviously been urinating on all the trees and had left their essence scattered hither and yon. The Air Force decided not to pursue this inquiry.
10The Kerr cell, invented in Scotland in 1875 by the physicist John Kerr, consists of two parallel electrode plates separated by a layer of nitrobenzene. Apply electricity across the electrodes, and the liquid develops interesting optical properties. It becomes birefringent to polarized light, refracting it off in two directions. The effect will switch on and off with incredible speed on the nanosecond scale. This property was exploited in the rapatronic camera, invented by Harold Edgerton of MIT, for use recording motion pictures of atomic bombs exploding at the tops of steel towers. These movies, only ten frames long, break an event that lasts a few milliseconds down into a slow-moving sequence, with the rapidly evolving explosion frozen in time. Watching it, you can see the fireball erupt from the bomb as the overrunning X-ray shock waves travel down the guy wires of the tower and cause them to evaporate. The tower has no time to be blown out of the way as it reduces to plasma under the spherical shock. It’s a rare spectacle of two divergent theories operating in the same photograph. Quantum mechanics eat the tower, while Newtonian mechanics (inertia) make it stand still.
11Blondlot would later employ a “rotary interrupter” to modulate the primary coil in his Ruhmkorff setup. This was a disc made of an electrically insulating material having a conducting stripe of copper foil adhered to the surface. The disc was spun at a high, constant speed by being fastened directly to the axle of an electric motor. As the disc spun, two spring-loaded electrical feelers would bear against the surface and make a periodic on/off connection through the copper strip to the battery driving the Ruhmkorff. The rotary switch setup may have improved the sputtering, inconsistent quality of the high-voltage spark.
12The “Auer burner” was invented by Carl Auer von Welsbach, an Austrian scientist, in 1890. It was a new way to use a gas flame for light, employing a mantle made of a mixture of thorium dioxide and cerium oxide. Instead of a dim, yellow flame, an Auer burner glowed brilliant white from the fluorescence of the thorium-cerium combination, and it turned out to be a strong source of N-rays. Think Coleman lantern. Carl went on to invent the cigarette lighter flint.
13It has been said, as a slur attributed to Robert W. Wood, that “only Frenchmen could observe the phenomenon.” This is an exaggeration. J. S. Hooker and Leslie Miller, both Englishmen, and F. E. Hackett, a student at the Royal University of Ireland, reported N-ray observations. Miller was the first to exploit N-rays for profit, selling a manufactured device for finding them and advertising it in Lancet.
14This is obviously a case of the “Hieronymus Effect” taking the place of objective instrumentation, and the attributes of N-rays corresponded with the Hieronymus “eloptic” rays. The researchers at Nancy had even confirmed that the “physiological rays” to and from living things could be collected by a metal plate and conducted along a wire. Blondlot may have been deluded by his experimental results, but he was not a complete fool. He had, in fact, recorded many of his spark-gap brightness measurements on photographic plates, correctly thinking that eyes could be fooled, but not photographs. The extent that a photographic emulsion is exposed by the light from a spark over a fixed unit of time should be an unimpeachable recording. Wood saw it differently. Watching a demonstration of Blondlot’s photo-recording techniques, he could see how subtle biasing of the exposure time or processing duration could throw the measurement to a consciously or even subconsciously desired outcome. There was a troubling possibility of skullduggery at work in this laboratory. It was traditional to split the monetary proceeds of a research award with the lab assistants, and if they would score a Nobel with this discovery, the reward would be substantial. The assistants, who have never been named, could have thrown out any photographic evidence that there was no N-ray effect, and kept only those that confirmed what Blondlot wanted to see.
