under any circumstances, to be considered as having any truth whatever to it. It's obviously utterly impossible ... isn't it? S-Regions." Owing to its unassuming title the startling implications implications are discussed here in an exclusive interview with Dr. Niemand by Philip Latham. LATHAM. Dr. Niemand, what would you say is your main job? can between activity on the Sun and various forms of activity on the LATHAM. What do you mean by activity on the Sun? describe it. A sunspot is a region on the Sun that is cooler than its surroundings. That's why it looks dark. It isn't so hot. Therefore not LATHAM. Isn't it true that the number of spots on the Sun rises and eleven years. That word makes quite a difference. LATHAM. In what way? of sunspot activity. Sunspots are mighty treacherous things. LATHAM. Haven't there been a great many correlations announced between sunspots and various effects on the Earth? LATHAM. What is your opinion of these correlations? LATHAM. But some are valid? NIEMAND. A few. There is unquestionably a correlation between sunspots and disturbances of the Earth's magnetic field ... radio fade-outs ... auroras ... things like that. LATHAM. Now, Dr. Niemand, I understand that you have been investigating solar and terrestrial relationships along rather unorthodox lines. NIEMAND. I think our biggest advance was the discovery that sunspots studying on the Earth. It's something like the eruptions in rubeola. a conspicuous symptom of the disease. Whereas the real cause is an LATHAM. Why S-Regions? suitable instrumental methods. It is extremely doubtful, however, if the radiation we detect is the actual cause of the disturbing effects observed. ever since the days of Job. And like Job they have usually given up in despair, convinced that the origin of evil is too deep for the human science has thrown new light on this subject. LATHAM. How is that? for no detectable reason —conditions are bloodshed and misery. LATHAM. But weren't there reasons? NIEMAND. What reasons? LATHAM. Well, disputes over boundaries ... economic rivalry ... border incidents.... NIEMAND. Nonsense. Men always make some flimsy excuse for going to war. The truth of the matter is that men go to war because they want to go to war. They can't help themselves. They are impelled by forces over which they have no control. By forces outside of themselves. specific? NIEMAND. I'm afraid that old stress-and-strain theory has been badly overworked. Been hearing about it ever since I was a pre-med student at ucla . Even as a boy I can remember my grandfather deploring the stress and strain of modern life when he was a country doctor practicing in Indiana. In my opinion one of the most valuable contributions anthropologists have made in recent years is the discovery that Latham, it's time the stress-and-strain theory was relegated to the junk pile along with demoniac possession and blood letting. inquiry into their personal life. Here again I drew a blank. They had no particular financial worries. Their sex life was generally satisfactory. There was no history of mental illness in the family. In fact, the only remedies for a patient. To my way of thinking it is a lazy slipshod way of carrying on the practice of medicine. The only thing for which I do give myself credit was that I asked my patients to keep a detailed record of their symptoms taking special care to note the time of exacerbation—increase in the severity of the symptoms—as accurately as possible. LATHAM. And this gave you a clue? LATHAM. Coincidences? became convinced it could not be attributed to chance. A mathematical disturbed around the time of full moon, but a search of medical literature failed to reveal any connection with the Sun. however, take pains to impress upon them the necessity of keeping an simultaneously, why not people hundreds or thousands of miles apart? It was this idea that prompted me to get in touch with an old colleague of mine I had known at UC medical school, Dr. Max Hillyard, who was in practice in Utica, New York. been getting an increasing number of patients suffering with the same identical symptoms as my own. Furthermore, upon exchanging records we did find that in many cases patients three thousand miles apart had gave us another clue. LATHAM. Which was? had to be above the horizon at both places. A person might undergo an attack soon after sunrise in New York but there would be no corresponding record of an attack in California where it was still dark. had both noticed that the attacks occurred only during the daylight evidence pointing directly to the source of trouble. It must have some connection with the Sun. the consequences. Here luck played somewhat of a part, for Hillyard happened to have a contact that proved invaluable to us. Several years before Hillyard had gotten to know a young astrophysicist, Henry Middletown, who had come to him suffering from a severe case of myositis cure for which the boy was very grateful, and they had kept up a desultory correspondence. Middletown was now specializing in radio astronomy at the government's new solar observatory on Turtle Back Mountain in Arizona. If it had not been for Middletown's help I'm afraid our investigation would never have gotten past the clinical stage. LATHAM. In what way was Middletown of assistance? NIEMAND. It was the old case of workers in one field of science being completely ignorant of what was going on in another field. Someday we will have to establish a clearing house in science instead of keeping it packed up for Arizona with considerable misgivings. We were afraid Middletown wouldn't take our findings seriously but somewhat to our surprise he heard our story with the closest attention. I guess astronomers have gotten so used to hearing from flying saucer enthusiasts and science-fiction addicts that nothing surprises them any at intervals of twenty-seven point three days. NIEMAND. Because the average period of solar rotation in the sunspot forty-eight hours between the two. But otherwise they were almost optical telescope, but are detected with ease by a had discovered them when he was a graduate student working on radio astronomy in Australia, and he had followed up his researches with the more powerful equipment at Turtle Back Mountain. The formation of an about ten or twelve days. How does that tie-in with the S-Regions? just coming on or just going off the disk of the Sun. LATHAM. Are the S-Regions associated with sunspots? NIEMAND. They are connected in this way: that sunspot activity and S-Region activity certainly go together. The more sunspots the more one-to-one correspondence between sunspots and S-Regions. That is, you cannot connect a particular sunspot group with a particular S-Region. The same thing is true of sunspots and magnetic storms. LATHAM. What other properties of the S-Regions have you discovered? constant while one is passing across the Sun. If the magnetic field forty-eight hours between the development of an S-Region and the onset some degree. Just why some speculation. LATHAM. How long does an S-Region last? entirely different region of the Sun. Sometimes there may be several LATHAM. Why were not the S-Regions discovered long ago? enough numbers to attract attention. Also the present sunspot cycle LATHAM. Is there no way of escaping the S-radiation? NIEMAND. I'm afraid the only sure way is to keep on the unilluminated on the Sun. But a new one may develop at any time. Also, the outlook for a decrease in activity is not very favorable. Sunspot activity continues LATHAM. And so you believe that the S-Regions are the cause of most of LATHAM. Could we not be warned of the presence of an S-Region? malignant radiation know that one of these regions is active? be with us ... as long as the Sun shall continue to shine upon this little world.
