<passage>:
whatever to it. It's obviously utterly impossible ... isn't it? An interview with Dr. I. M. Niemand, Director of the Psychophysical Institute of Solar and Terrestrial Relations, Camarillo, California. In the closing days of December, 1957, at the meeting of the American Association for the Advancement of Science in New York, Dr. Niemand delivered a paper entitled simply, "On the Nature of the Solar LATHAM. Haven't there been a great many correlations announced between 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. Yes, I suppose some people would say so. NIEMAND. That's true. LATHAM. In what way have your investigations differed from those of themselves are not the direct cause of the disturbances we have been NIEMAND. Well, they're common enough, goodness knows. As old as the NIEMAND. Well, Shakespeare would have been nearer the truth if he had LATHAM. But weren't there reasons? NIEMAND. What reasons? LATHAM. Aren't such attacks characteristic of the stress and strain of 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 Latham, it's time the stress-and-strain theory was relegated to the junk LATHAM. You must have done something for your patients— NIEMAND. A doctor must always do something for the patients who come to his office seeking help. First I gave them a thorough physical examination. I turned up some minor ailments—a slight heart murmur or a NIEMAND. Oh, yes. In a few cases in which I tried tranquilizing pills of Another that he felt the people around him were plotting his destruction. One housewife made her husband lock her in her room for fear she would injure the children. I pored over these case histories NIEMAND. The first thing that struck me was that the attacks all morning and five in the evening. Then there were these coincidences— LATHAM. Coincidences? NIEMAND. Total strangers miles apart were stricken at almost the same literature failed to reveal any connection with the Sun. LATHAM. What did you do? NIEMAND. Naturally I said nothing of this to my patients. I did, occurred to me: if people a few miles apart could be stricken 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 LATHAM. With what result? NIEMAND. I was afraid the result would be that my old roommate would on receiving an answer by return mail to the effect that he also had identical symptoms as my own. Furthermore, upon exchanging records we did find that in many cases patients three thousand miles apart had been stricken simultaneously— NIEMAND. We say an attack is simultaneous when one occurred on the east gave us another clue. LATHAM. Which was? LATHAM. You mean if it was cloudy— 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 Conversely, a person might be stricken late in the afternoon in California without a corresponding attack in New York where the Sun had set. Dr. Hillyard and I had been searching desperately for a clue. We had both noticed that the attacks occurred only during the daylight hours but this had not seemed especially significant. Here we had evidence pointing directly to the source of trouble. It must have some connection with the Sun. LATHAM. That must have had you badly puzzled at first. NIEMAND. It certainly did. It looked as if we were headed back to the Middle Ages when astrology and medicine went hand in hand. But since it 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 in the arms and shoulders. Hillyard had been able to effect a complete 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 in tight little compartments as we do at present. Well, Hillyard and I 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 more. When we had finished he asked to see our records. Hillyard had NIEMAND. It was really quite simple. But if it had not been for Middletown produced another chart that showed the connection with the NIEMAND. I said that the lines drawn down through the days of greatest were dated under one another not at intervals of twenty-seven days, but NIEMAND. Middletown was immediately struck by the resemblance between solar chart but with this difference. The disturbances on the Earth started two days later on the average than the disturbances due to the forty-eight hours between the two. But otherwise they were almost identical. LATHAM. But if these S-Regions of Middletown's are invisible how could he detect them? optical telescope, but are detected with ease by a radio telescope. Middletown 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 NIEMAND. Apparently an S-Region is not particularly effective when it is NIEMAND. We don't account for it. NIEMAND. Middletown says that the radio waves emanating from them are strongly circularly polarized. Moreover, the sense of rotation remains constant while one is passing across the Sun. If the magnetic field NIEMAND. Our latest results indicate that probably entirely different region of the Sun. Sometimes there may be several different S-Regions all going at once. LATHAM. Why were not the S-Regions discovered long ago? NIEMAND. Because the radio exploration of the Sun only began since the end of World War II. LATHAM. How does it happen that you only got patients suffering from NIEMAND. I think we did get such patients previously but not in large NIEMAND. I'm afraid the only sure way is to keep on the unilluminated NIEMAND. That is the logical outcome of our investigation. We are LATHAM. Could we not be warned of the presence of an S-Region? NIEMAND. The trouble is they seem to develop at random on the Sun. I'm afraid any warning system would be worse than useless. We would be LATHAM. How may a person who is not particularly susceptible to this malignant radiation know that one of these regions is active? NIEMAND. If you have a feeling of restlessness and anxiety, if you are Middletown believes that the Intense radiation recently discovered from information derived from Explorer I and III has no connection with the corpuscular S-radiation.
