Discovered by accident on long-exposure photographic plates, the object, called Malin 1, appears to be still forming. .. .. .. "' We didn't expect to find anything like this,' (C .) Impey says, referring to Malin 1. 'This galaxy is far removed from our ideas of what a normal galaxy should look like. There could be more of these things that haven't been discovered yet.'" (Anonymous; "Massive, Dark Galaxy Found in Void," Astronomy, 15:75, September 1987.) The same discovery is dealt with, in a more technical way, in Nature. A revealing paragraph from the Nature article follows: "Although Malin 1 could be a unique case there is in fact a significant body of circumstantial evidence to suggest otherwise. Our present knowledge of the galaxy population is so biased by a single insidious selection effect that it is entirely possible that Malin 1 is just the first example of a class of such low-surface-brightness giant galaxies that forms a significant constituent of the universe." The "selection effect" mentioned is a consequence of the very bright sky that confronts astronomers. Astronomical interest and instrumentation have focussed ...

Science Frontiers ONLINE No. 12: Fall 1980 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Little big bangs!The photographic enhancement of plates taken by the UK Schmidt and Anglo-Australian telescopes has revealed that several normal elliptical galaxies are surrounded by shell-like structures. D.F . Malin and D. Carter report that these envelopes are vast -- up to 180 kiloparsecs in diameter. Furthermore, some galaxies are wrapped in a series of thin shells. Malin and Carter believe that the colossal shells are really thin layers of stars either created by a powerful shock wave during galaxy formation or comprised of a debris layer of old stars blown out of the galaxy during some cataclysmic event. (Malin, David F., and Carter, David; "Giant Shells around Normal Elliptical Galaxies," Nature, 285:643, 1980.) Comment. This article typifies the emergence of "catastrophic astronomy" which contrasts sharply with the older vision of a leisurely evolution of stars and galaxies.

... Science Frontiers ONLINE No. 7: June 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Deadly Sun Sunspottery, or the linking of seemingly unrelated phenomena to solar activity, has been a popular pastime for as long as sunspot records have been kept. Usually pooh-poohed by scientists because the link between cause and effect seems absent, some impressive statistical evidence now associates heart attacks with geomagnetic and solar activity. Malin and Srivastava have shown that the number of cardiac emergencies in their area of India is very closely tied to geomagnetic activity, which in turn is controlled by the sun. Standard statistical tests confirm an especially strong correlation. But why should the two observables be associated at all? The authors' concluding sentence reads: "The possibility that there is some other cause (or solar origin?) responsible for both the magnetic and medical phenomena should not be ignored." (Malin, S.R .C ., and Srivastava, B.J .; "Correlation between Heart Attacks and Magnetic Activity," Nature, 277:646, 1979.) Top Curve: Magnetic activity index. Bottom Curve: Daily admissions of cardiac emergiencies From Science Frontiers #7 , June 1979 . 1979-2000 William R. Corliss ...

... -Aug 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Slamming the door on parapsychology -- again An exchange of letters in the April issue of Physics Today demonstrates that an influential portion of mainstream science (particularly physics) is firmly committed to reductionism and objectivism. Translation: this faction wants no part of parapsychology. In the first letter, A.A . Berezin bravely proclaimed that science needs more rather than less research in parapsychology, citing specifically the work of H. Schmidt and R. Jahn. Further, he maintains that the major science journals should be open to high quality research in parapsychology. He wrote: "One cannot exorcise unorthodox claims by repeating mantras that they are 'pseudoscience.'" A second letter from S. Malin begins by noting that physics has undergone two major paradigm shifts during its history: (1 ) Aristotelian to Newtonian physics; and (2 ) Newtonian to contemporary physics. Additional shifts are likely, and the next one might well involve the relation of consciousness to the physical world. In support of his intuition, he quoted from E. Schroedinger's 1958 book Mind and Matter on the "principle of objectivation." "By this I mean what is also frequently called the 'hypothesis of the real world' around us. I maintain that it amounts to a certain simplification which we adopt in order to master the infinitely intricate problem of nature. Without being aware of it and without being rigorously systematic about it, we exclude the Subject of Cognizance from the domain of nature that ...
