By PHILIP LATHAM Niemand by Philip Latham. LATHAM. Dr. Niemand, what would you say is your main job? Earth. LATHAM. What do you mean by activity on the Sun? LATHAM. In what way? NIEMAND. It means you can only approximately predict the future course 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? NIEMAND. Scores of them. LATHAM. What is your opinion of these correlations? NIEMAND. Pure bosh in most cases. 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 NIEMAND. Yes, I suppose some people would say so. LATHAM. You have broken new ground? NIEMAND. That's true. LATHAM. In what way have your investigations differed from those of others? NIEMAND. I think our biggest advance was the discovery that sunspots themselves are not the direct cause of the disturbances we have been studying on the Earth. It's something like the eruptions in rubeola. Attention is concentrated on the bright red papules because they're such a conspicuous symptom of the disease. Whereas the real cause is an NIEMAND. It is quite invisible to the eye but readily detected by radiation we detect is the actual cause of the disturbing effects observed. LATHAM. Just what are these effects? LATHAM. Can you give us a general idea? NIEMAND. I'll try. Let's see ... remember that speech from "Julius LATHAM. I'm afraid I don't see— NIEMAND. Well, Shakespeare would have been nearer the truth if he had LATHAM. How is that? for no detectable reason —conditions are reversed. Wars rage. People go mad. The world is plunged into an orgy of bloodshed and misery. LATHAM. But weren't there reasons? NIEMAND. What reasons? LATHAM. Those are broad, sweeping statements. Can't you be more NIEMAND. Perhaps I'd better go back to the beginning. Let me see.... It 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 NIEMAND. A doctor must always do something for the patients who come to exacerbation—increase in the severity of the symptoms—as accurately as possible. LATHAM. And this gave you a clue? NIEMAND. It was the beginning. In most instances patients reported the LATHAM. What sort of pattern? LATHAM. Coincidences? NIEMAND. Total strangers miles apart were stricken at almost the same LATHAM. What did you do? NIEMAND. Naturally I said nothing of this to my patients. I did, LATHAM. With what result? NIEMAND. I was afraid the result would be that my old roommate would LATHAM. Just a minute. I would like to know how you define LATHAM. Which was? LATHAM. That must have had you badly puzzled at first. LATHAM. In what way was Middletown of assistance? LATHAM. Can you describe this chart for us? NIEMAND. It was really quite simple. But if it had not been for LATHAM. In what way? solar rotation. That is, if you see a large spot at the center of the Sun's disk today, there is a good chance if it survives that you will see it at the same place twenty-seven days later. But that night LATHAM. How was that? NIEMAND. I said that the lines drawn down through the days of greatest LATHAM. Why is that so important? NIEMAND. Middletown was immediately struck by the resemblance between the resemblance between the two was unmistakable. The pattern shown by the chart of mental disturbance corresponded in a striking way with the solar chart but with this difference. The disturbances on the Earth started two days later on the average than the disturbances due to the S-Regions on the Sun. In other words, there was a lag of about LATHAM. But if these S-Regions of Middletown's are invisible how could he detect them? more powerful equipment at Turtle Back Mountain. The formation of an S-Region is heralded by a long series of bursts of a few seconds duration, when the radiation may increase up to several thousand times that of the background intensity. These noise storms have been recorded simultaneously on wavelengths of from one to fifteen meters, which so far is the upper limit of the observations. In a few instances, however, S-Region to pass across the face of the Sun, since the synodic rotation is twenty-seven point three days. LATHAM. I should think it would be nearer thirteen or fourteen days. S-Region activity certainly go together. The more sunspots the more violent and intense is the S-Region activity. But there is not a one-to-one correspondence between sunspots and S-Regions. That is, you cannot connect a particular sunspot group with a particular S-Region. LATHAM. How do you account for this? NIEMAND. We don't account for it. NIEMAND. Middletown says that the radio waves emanating from them are LATHAM. Does this mean that the mental disturbances arise from some form of electromagnetic radiation? NIEMAND. We doubt it. As I said before, the charts show a lag of about forty-eight hours between the development of an S-Region and the onset of mental disturbance. This indicates that the malignant energy emanating from an S-Region consists of some highly penetrating form of LATHAM. A question that puzzles me is why some people are affected by NIEMAND. Our latest results indicate that probably should be affected so much more than others is still a matter of speculation. LATHAM. How long does an S-Region last? NIEMAND. An S-Region may have a lifetime of from three to perhaps a dozen solar rotations. Then it dies out and for a time we are free from this malignant radiation. Then a new region develops in perhaps an entirely different region of the Sun. Sometimes there may be several different S-Regions all going at once. LATHAM. How does it happen that you only got patients suffering from NIEMAND. I'm afraid the only sure way is to keep on the unilluminated side of the Earth which is rather difficult to do. Apparently the corpuscular beam from an S-Region is several degrees wide and not very sharply defined, since its effects are felt simultaneously over the 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 at a high level and is steadily mounting in violence. The last sunspot cycle had the highest maximum of any since 1780, but the present cycle bids fair to set an all time record. NIEMAND. That is the logical outcome of our investigation. We are LATHAM. How may a person who is not particularly susceptible to this NIEMAND. If you have a feeling of restlessness and anxiety, if you are about yourself, or are filled with resentment toward the world, then you may be pretty sure that an S-Region is passing across the face of the Sun. Keep a tight rein on yourself. For it seems that evil will always be with us ... as long as the Sun shall continue to shine upon this little world. THE END [A] Middletown believes that the Intense radiation recently discovered from information derived from Explorer I and III has no
