It is basically a running commentary on new discoveries that are helping us to understand this poorly appreciated relationship. Maddox begins by mentioning the 20-plus-year collection compiled by Professor G.W . Brown, University of London, of life-events that affect the health of outwardly normal people. Typical life-events are the death of a spouse, imprisonment, personal bankruptcy, etc. Everyone seems to recognize -- if only through anecdotes -- that mental states affect health, but how this brain-body link is maintained is hard to pin down. D. Maclean and S. Reichlin (Psychoneuroimmunology, 12: 475, 1981.) have reviewd some of the possible connections. One potential link is through the interaction of the hypothalamus on the pituitary. The pituitary is a source of materials that influence the immune system. Maddox lists several specific candidates, and then observes: "The more radical psychoimmunologists talk as if there is no state of mind which is not faithfully reflected by a state of the immune system." So far, not too radical! But then Maddox comes to an article by J.E . Blalock, University of Texas (Journal of Immunology, 132: ...

Here, let us assume that it really does exist, even though we cannot see it. From a new book by I. Asimov (title below), we learn that this remote haze of icy fluff, the Oort Cloud, may really have about 90% of the angular momentum of the entire solar system. It was already sufficiently anomalous to discover that the planets possess fifty times the angular momentum of the much more massive sun. (See ABB3 in The Sun and Solar System Debris.) Astronomers have been attempting for years to explain this 50:1 split. Now, with the Oort Cloud apparently having ten times the angular momentum of the planets, the situation is much worse. According to Asimov, the solar-system angular momentum is split as follows: Oort Cloud 90% All of the planets 9.8 % The sun 0.2 % The total mass of the Oort Cloud is estimated to be roughly that of Saturn. The recent flyby of Halley's Comet created this dilemma. It was discovered that Halley was a chunk containing 140 cubic miles of ice - much larger than anticipated for this "typical" comet. If the estimated 2 trillion comets are, on the average, Halley' ...

"Newton's equations have chaotic solutions as well as regular solutions. The solar system is generally perceived as evolving with clockwork regularity, yet there are several physical situations in the solar system where chaotic solutions of Newton's equations play an important role. There are physical examples of both chaotic rotation and chaotic orbital evolution. "Saturn's satellite Hyperion is currently tumbling chaotically, its rotation and spin axis orientation undergo significant irregular variations on a time scale of only a couple of orbit periods. Many other satellites in the solar system have had chaotic rotations in the past. It is not possible to tidally evolve into a synchronous rotation without passing through a chaotic zone. For irregularly shaped satellites this chaotic zone is attitude-unstable and chaotic tumbling ensues. This episode of chaotic tumbling probably lasts on the order of the tidal despinning timescale. For example, the Martian satellites Phobos and Deimos tumbled before they were captured into synchronous rotation for a time interval on the order of 10 million years and 100 million years, respectively. This episode of chaotic tumbling could have had a significant effect on the orbital histories of these satellites." Theis abstract continues, naming as other candidates for chaotic histories: some of the asteroids, Miranda (a satellite of Uranus), and the planet Pluto. ...

This is not correct. On the contrary, the clarifica-tion of the nature of space and time in this theoretical development removes the obstacles that have hitherto prevented science from conceding the existence of anything outside the boundaries of the physical realm. "In conventional science, space and time constitute a framework, or setting, within which the entire universe is contained. On the basis of this viewpoint, everything that exists, in a real sense, exists in space and in time. Scientists believe that the whole of this real universe is now within their field of observation, and they see no indication of anything non-physical. It follows that anyone who accepts the findings of conventional science at their face value cannot accept the claims of religion, or any other non-material system of thought. This is the origin of the long-standing antagonism between science and religion, a conflict which most scientists find it necessary to evade by keeping their religious beliefs separate from their scientific beliefs.

In this view, the inner terrestrial planets differ from the outer giant planets only because their volatile elements were driven off by the sun's heat. This scenario has many problems, as recorded in our catalog volume The Moon and the Planets. G.H .A . Cole thinks that astronomers might have more success in explaining the origin of the solar system if they considered it a system of five large bodies of star stuff (light elements), each surrounded by its own retinue of high density satellites (the sun's four satellites would be the inner planets). In effect, then, we would have a quintuple star system in which only one member (the sun) collected enough star stuff to make it to incandescence. The four, large, outer planets would be merely failed stars. The advantages of this change of perspective are threefold: (1 ) All five central bodies are now compositionally similar as a class, (2 ) In each of the five systems, the angular momentum of the central body is greater than that of its satellites, whereas in the unitary solar system the angular momentum of the nine planets is much greater than that of the sun -- an embarrassing anomaly.

No one has been able to predict its future course accurately. Already this maverick planet is drifting off the orbit predicted just 10 years ago using the best data and solar-system models. All of the outer planets, in fact, confound predictions to some degree. In addition, some long-period comets have anomalous orbits. Astronomers have been aware that something was wrong for decades and anticipated finding a trans-Neptunian planet large enough to perturb the outer solar system. The discovery of Pluto did not help matters; it is much too small. The most popular explanation of the orbital anomalies relies on a large, still-undetected planet, possibly 3-5 times the mass of the earth, swinging sround the sun at some 80-100 Astronomical Units. But many have searched and no one has found anything. Planet-X , as it is often called, is just another bit of "missing mass." Thomas C. Van Flandern and Robert Harrington propose that all the obvious orbital damage in the outer solar system is the result of a single encounter between Neptune and another body, call it Planet X if you wish, that was passing through the outer reaches of the solar system.

Comets are supposed to be as old as the solar system itself (4 .6 billion years), born of solar-system stuff when a gaseous cloud condensed. Above all, comets do not "burn" or combust! The vision of a "burning" comet was advanced by recent observations that the velocity and temperature of the gases escaping from Halley are higher than one would expect from the sublimation of ices under solar radiation. Also, the concentration of expelled material in large, hypersonic jets carrying large quantities of fine dust further undermine the sublimation model. E.M . Drobyshevski has concluded "The new observations, together with some earlier data still poorly understood (e .g ., the appearance in the coma of large amounts of C3 ) can be accounted for by assuming the cometary ices to contain, apart from the hydrocarbons, nitrogen-containing compounds, etc., also of free oxygen (about 15 wt. %) . Under these conditions, burning should occur in the products of sublimation under deficiency of oxidizer accompanied by the production of 'soot,' 'smoke,' etc. The burning should propagate under the surface crust and localize at a few sites. "The presence of oxygen in cometary ices follows from a new eruption theory assuming the minor bodies of the Solar System to have formed ...

Not only is the magnetic axis of Uranus tilted grotesquely away from the planet's axis of rotation, but the latter lies almost in Uranus' orbital plane. Q1. Why are the magnetic fields of Neptune and Uranus tilted at such grotesque angles with the axes of rotation? A1. Probably because of giant impacts. Q2. "Why does Mercury have an iron core twice as massive, relative to its size, as any other rocky planet?" A2. Probably because a giant impact tore off its rocky mantle. Q3.

Planet X has never been found, but somewhere out there are some pretty hefty bodies, as described by T. Van Flandern: "The discovery of a second miniplanet beyond Neptune, 1993 FW, augments the discovery of 1992 QB1 last fall. Both objects are believed to be in the 200-300-km-diameter range, with magnitudes between 2324, distances at discovery between 40-45 AU, and low inclinations.... Although the discoverers of these two objects hailed them as the first representatives of the elusive 'Kuiper belt' of comets, other theoreticians have confirmed that the line of reasoning leading to the suggestion of such a belt is spurious. That fact, combined with the absence of any comet-like characteristics in these two new objects, their relative size as compared with any other known comet, and their unusually red coloration, seem to make them the first-discovered members of a new class of solar system bodies. Since the searches leading to their discovery have examined only 1.5 out of tens of thousands of square degrees of sky wherein such objects might be discovered, it seems a reasonable conjecture that thousands of additional similar objects will ultimately be found.

Becker, author of Cross Currents , has contributed a thought-provoking article on the mechanisms by which humans perceive the cosmos. From the many stimulating ideas he presented, we select his rationale for believing that an electromagnetic basis may exist for the reception and processing of psi signals. A key concept in Becker's scheme is his belief in the presence, in humans and other organisms, of a dual system for receiving and processing information arriving from the environment. The system we are all aware of and which scientists study in depth is the nerve impulse system, which transmits digital signals; i.e ., 0s and 1s. This system connects to all our everyday senses and controls our motor functions. The second system Becker designates as "primitive." It transmits information in analog (continuously varying) form via electrical currents and magnetic fields, rather than as impulses along neurons. This second system is not recognized by mainstream science. Becker advances the notions that: (1 ) Psi-type phenomena are actually handled by the "primitive" analog system; (2 ) The flood of information normally arriving from our sensory organs via the "modern" digital system masks the psi-type signals; and (3 ) These assertions are consistent with the elusive nature of psi phenomena in both everyday experience and the parapsychological laboratories.

Chaotic systems are usually qualitatively predictable but not quantitatively predictable. We have no choice but to live with this chaos; it seems that that's the way the cosmos is constructed! However, it now seems that the situation is even worse than chaotic! Some systems, perhaps most systems, are also indeterminate, meaning that we cannot predict their qualitative behavior either. A simple example is the water swirling down the bathtub drain. This is not only chaotic but it has two qualitative final states: clockwise and counterclockwise. Regardless of which hemisphere you are in, you can change the direction of swirl with negligible effort. Each of the two final states of motion is still quanti tatively unpredictable. Systems that are more complex will possess many different final states, all chaotic. Can nature really be fundamentally chaotic as well as qualitatively uncertain? J.C . Sommerer and E. Ott have mathematically examined a relatively simple system consisting of a single particle moving in a force field, experiencing friction, and being periodically jolted. Besides settling into chaotic motion, this particle may also be forced away to infinity -- two radically different final states. The analysis revealed that for any ...

No one has yet seen the Oort Cloud directly, but the textbooks say that it must be there. In fact, all stars like our sun with planetary systems should have their own private Oort Clouds of comets - if the prevailing theory of planetary-system formation is correct. When we see a comet looping around the sun, it is because it has been jostled loose from the Oort Cloud by a passing star or molecular cloud. Further, some of these jostled comets should be kicked outwards and thus escape the solar system. Continuing with this reasoning, we on earth should sometimes see interstellar comets that have been shaken loose from other stellar systems. But we don't ! T.A . McGlynn and R.D . Chapman worry about this. "This lack of detections of extrasolar comets is becoming an embarrassment to the theories of solar system and comet formation." McGlynn and Chapman calculate that we should have seen six interstellar comets in the past 150 years, but the actual number is zero.

Two possible explanations for the missing interstellar comets are: (1 ) The Oort Cloud theory is wrong; and (2 ) Solar systems like ours are rarer ...

Most doctors admit they sometimes work for some people. Why, they don't know. Placebo action seems closely allied to a person's mental attitude. Many doctors will also allow that a positive attitude helps a lot in fighting illness and that depression aggravates it. Visualization techniques, though, are hotly debated. Will cancer cells be destroyed, or at least stop growing, if the patient visualized them as weak things that are vulnerable to the body's killer cells? Proponents of visualization recom-mend that a cancer patient visualize his killer cells as protecting knights in armor that swoop down and skewer the enemy cancer cells. In a visualization session, one focuses one's mind on such images and, in essence, wills his body to fight back. There is some evidence that visualization helps.

The General Theory should also account for the precessions of double-star orbits, but a serious anomaly has been found. The double star DI Herculis has a Newtonian precession rate of 1.93 degrees per century, with another 2.34 added by relativistic effects. With more than 3,000 well-observed orbits of this star system on the books, astronomers come up with only 0.64 degree per century, instead of the 4.27 predicted by theory. Something is obviously awry; and all searches for errors and other influences on the orbit have been negative. (Anonymous; "Double-Star System Defies Relativity," New Scientist, p. 23, August 29, 1985.) Comment.

By comparing the times of arrival of the burst, the direction of the source was narrowed down to a "box" a couple of arc minutes across. Gamma-ray bursts have never before been correlated with visible sources, but this time the box contained the remnants of a supernova in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. The anomaly that arises involves the immense distance of the supposed source and the strength of the burst when it reached the solar system.

(L . Stansass, M. Reingold) First: An Anecdote. Some 30 years ago, D. Berliner, at the University of Utah, was studying human skin. To acquire raw material, he scraped skin cells from the insides of casts discarded by skiiers who had had broken bones. From this debris, Berliner extracted numerous chemical compounds. As far as anyone could tell, these substances were odorless, so he stored them in open flasks. However, Berliner noticed that when people were working in the lab with the flasks, they were more friendly and relaxed than normal. He could not divine the reason until some months later when he decided to cover the flasks of skin-derived substances. Curiously, the lab workers soon reverted to their usual grumpy selves! What could account for this strange behavior change? Knowing that animals often communicated with one another employing chemicals called pheromones, Berliner suspected that the flasks had been releasing odorless human pheromones. Sure enough, analysis of the skin-derived materials proved him correct. Next: A Look Up the Nose. Biologists have long realized that animal noses actually contain two sensory channels. The first is the familiar olfactory system, which humans also possess. The second channel is the vomeronasal system.

In the U.S . western interior, rhythmic sedimentation appears in the Fort Hays Limestone Member of the Niobrara Formation. These cyclothems can be correlated over distances exceeding 800 kilometers and are believed to be the consequence of climatic changes associated with the earth's precession and orbital eccentriciy. These rhythms have been captured in bundles of shale-limestone couplets. A bundle of five coup lets, for example, is thought to express 21,000- and 100,000-year Milankovitchtype climatic cycles, as impressed by variations in the earth's orbital precession and eccentricity. Analysis of the Fort Hays Limestone Member, however, reveals that while bundles of five couplets do occur, the number may vary from 1 to 12. Clearly, things are not clear-cut.

Happy, unstressed people get fewer colds. Introverts get worse colds than extroverts. Men who have just lost their wives have lowered white-cell responses. Although many physicians and medical researchers think it too early to claim that mental stress significantly suppresses the human immunological system and thus leads to more illness, one can see the pendulum start to swing away from the timehonored belief that mind and body are entirely separate entities. The foregoing studies and others like them are discussed in a recent survey of psychoimmunology by B. Dixon. Toward the close of the article, Dixon asks why humans (and other animals, too) have evolved an immunological system sensitive to stress. Evolutionists can always find some sort of justification in Darwinian terms, and Dixon's is rather ingenious. Suppose a primitive human was attacked by a saber-toothed tiger (what else?). If the human survived, his immunological system would immediately go into high gear to clean up the wounds and repel invading germs. The trouble is that a revved-up immunological system (especially the white blood cells) can go too far and chomp up healthy tissue, too. However, evolution has constructed animals such that stress (saber-toothed tigers are stressful! ...

Now it seems that they may have been a bit hasty and all-encompassing. Not that the Velikovsky scenario is correct or that Mars might at any moment depart from its present orbit, but rather that astronomers must now admit an inability to predict planetary motion over billions of years - even tens of millions of years! For the solar system, if those ubiquitous computers are correct, is not a well-behaved family of planets. J. Laskar concludes from extensive numerical experiments: "The motion of the Solar System is thus shown to be chaotic, not quasiperiodic. In particular, predictability of the orbits of the inner planets, including the Earth, is lost with a few tens of millions of years."

After some computations Melosh concludes: "It seems likely that the impacts that produced craters on Earth that are greater than 100 km in diameter would each have ejected millions of tons of near-surface rocks carrying viable microorganisms into interplanetary space, much in the form of boulders large enough to shield those organisms from ultraviolet radiation, low-energy cosmic rays, and even galactic cosmic rays.

First, E.G .

"The most likely site for the inorgan ic construction or an RNA chain, which would have occurred in the Archaean, is in a hydrothermal system. Only in such a setting would the necessary basic components (CH4 , NH3 , and phosphates) be freely available. Suitable pH (fluctuating around 8) and temperatures around 40 C are characteristic of hydrothermal systems on land. Furthermore, altered lavas in the zeolite metamorphic facies, which are rich in zeolites, clays and heavy metal sulphides, would provide catalytic surfaces, pores and molecular sieves in which RNA molecules could be assembled and contained. If the RNA could then replicate with the aid of ribozymes and without proteins, the chance of creating life becomes not impossible but merely wildly unlikely." The article concludes with a statement that self-replicating molecules synthesized in hydrothermal systems would be pre-adapted to "life" in the open ocean if they "learned" to surround themselves with bags of lipids.

Their thesis is that the solar system periodically passes through the regularly spaced spiral galaxy arms every few 107 years. Planetesimals in these arms cra-ter the solar-system planets at these times and also provide the raw materials for new comets, asteroids, satellites, and even planets. Supporting their theory is the repeating history of geological revolutions with the accompanying extinctions and reflowerings of life. A remarkable feature of this paper is a table of shortlived solar-system phenomena (comets and rapidly evolving staellite-and-ring systems). The tenor is one of episodic catastrophism and a rapidly changing solar system; viz., Saturn's rings evolving in only 104 years.

The motion of Antarctica's ice sheet carries these meteorites conveyor-belt fashion out towards the encircling seas. But where Antarctic mountains get in the way, the rocky cargo tends to get concentrated. Several thousand meteorites have already been picked up at these favored spots. In just a few brief summers of searching, these massive finds have posed unexpected questions. Here is a sampling. The terrestrial ages (times since arrival on earth) measure between 1,000 and 700,000 years, implying that the Antarctic ice sheet may be at least 700,000 years old. This is unfortunate for several proposed scenarios of recent catastrophism, which envision an iceless Antarctica. At least 20 amino acids appear in the more than 40 carbonaceous chondrites picked up with sterile equipment. These meteorites are dated as 4.5 billion years old, or 1 billion years older than the earliest terrestrial life found in the rocks.

Eruptions of Old Faithful Geyser are generally perceived as extremely regular events, with variation of eruptive interval being attributed to random noise. The governing equations for such a hydrothermal system are highly non-linear, therefore it is reasonable to assume that such systems are capable of operating in regines that display chaotic behavior. Three-dimensional state-space reconstruction of eruption time data provides strong evidence of a strange attractor quite similar to the Rossler attractor. Establishing the system as chaotic indicates that while one can predict eruptive intervals in the short term, long term predictions regarding Old Faithful's eruptive behavior are impossible, no matter how carefully and accurately the system is modeled. The mean eruptive interval of Old Faithful has changed over time. This is consistent with the behavior of a chaotic system, which by definition must be nonstationary in the mean. Seismic activity is believed to be a perturbation shifting Old Faithful into a new chaotic state with a different shape to the strange attractor. A simple non-linear dynamic model of geyser behavior is proposed that leads to chaotic behavior and is consistent with the observations of eruption interval data for Old Faithful."

Astronomers are generally agreed that these bodies originate in a very distant (100,000 A.U .* ) halo of cometary material surrounding the entire solar system. J. Oort proposed this cloud, and it is named after him. Of course, we anomalists become wary when scientists "generally agree" on a hypothetical entity that no one can see. The Oort Cloud of comets, like the unseeable black holes, are given substance only by the effects they have on other solar-system denizens and seeable cosmic objects. But there may be another cloud of comets that we can view directly. It is called the Kuiper Cloud (after G. Kui per). It is concentrated in the plane of the ecliptic just beyond the orbit of Neptune. Like the Oort Cloud, the Kuiper Cloud has not been seen yet, but we just might be able to with today's equipment!

It is one of hundreds of icy TNOs (Trans-Neptunian Objects) that normally populate the Kuiper Belt girdling the solar system just beyond the orbit of Neptune. The problem is that 2000 CR105 is not normal. Its orbit is highly eccentric, with an aphelion 13 times farther out than Neptune's . This massive object (probably mostly ice) takes 3175 years to circle the sun. 2000 CR105 is real; it has been photographed; it is not Mirror Matter; no one blames any terrestrial extinctions on it. Nevertheless, we can and must wonder how its orbit became so badly distorted.

Indeed, there have been several intense and unsuccessful searches for Planet X over the years. (See Chapter AX in The Sun and Solar System Debris.) History seems to be repeating itself with 2000 CR105. Astronomer B.

Coupled with this is Walter Alvarez's recent observation that terrestrial impact craters 10kilometer-diameter and up have been blasted out episodically -- every 28.4 million years on the average. This figure is close enough to 26 million years to impel some astronomers to search for a periodic source of cosmic projectiles. R.A . Muller and M. Davis, at Berkeley, think they have found one. They postulate that the solar system is really a double-star system. Our sun's companion star has only about 0.1 solar mass and is so faintly luminous that we have not found it visually. It does, however, now cruise along its orbit some 2.4 light years away. But it will be back! In fact, it returns every 26 million years to jostle the Oord Cloud of comets that hovers on the fringe of the solar system.

The overwhelming majority of the angular momentum is tied up in planetary motion. To make matters even more puzzling, the angular-momentum vectors of the sun and the planetary system are 7 apart. The implication is that the sun and planets could not have been formed by the rapid condensation of a molecular cloud -- the present theory. Rapid condensation requires that the sun get a much bigger share of the angular momentum. These anomalies have led T. Gold to propose a slow-condensation model, in which several hundred million years are required rather than the tens of thousands of years in the current scenario. Another unexpected feature of Gold's model makes the sun a degenerate object, perhaps a neutron star.

In addition, there are unexplained perturbations in the orbits of earth satellites, peculiar periodicities in the sunspot cycle, and equally puzzling regularities in earthquake frequency. Infrared detectors have also picked up unidentified objects in the sky. These anomalies might all be explained by the existence of a large, dark planet with several moons -- or, if the mystery object turns out to be very far away, by a very large, dark stellar companion of our sun with its own system of planets.

... as a surprise when we find supposedly primitive organisms employing our highly technical concepts; for example, the jamming-avoidance techniques of electric fish (SF#89). Still another potential example has been advanced: The lowly crayfish is now thought to enlist some of our sophisticated information theory. Crayfish often live in noisy environments, where one would expect acoustical information transmission would be degraded. This would be true enough if linear information theory applied, but some, perhaps all, real situations are nonlinear. In such instances, information flow can actually be enhanced by the presence of optimized random noise. Stochastic resonance (SR) is the term applied in such cases of nonlinear statistical dynamics. J.K . Douglass et al write: "Although SR has recently been demonstrated in several artificial physical systems, it may also occur naturally, and an intriguing possibility is that biological systems have evolved the capability to exploit SR by optimizing endogenous sources of noise. Sensory systems are an obvious place to look for SR, as they excel at detecting weak signals in a noisy environment. Here we demonstrate SR using external noise applied to crayfish mechanoreceptor cells. Our results show that individual neurons can provide a physiological substrate for SR in sensory systems." Put more simply, the crayfish nervous system has the potential for cashing in on SR in noisy environments. However, the authors also remark that humans, too, accordingly to psychological experiments, seem to harness SR in the perception of ambiguous figures in noisy situations.

You do not have to be in an airplane to appreciate the lines; most can be viewed from ground level, even better from nearby foothills. Although there are some 1,300 kilometers of lines and about 300 geometric figures, their construction did not really involve much labor or special engineering skills. Even so, the Nazca lines are remarkable, and we really do not know for certain why they were etched on the Peruvian pampa. In his early research on the Nazca lines, Aveni noted their strong similarity to the ceque system of 41 imaginary lines radiating outwards from the Inca's Temple of the Sun, at Cuzco -- the "navel" of the Inca universe. ". .. the ceque system was a highly ordered hierarchical cosmographical map, a mnemonic scheme that incorporated virtually all important matters connected with the Inca world view."

Also, many of the lines definitely functioned as footpaths.

The reverse works, too, at least in experiments with mice. It seems that mice can be conditioned into believing that an ordinarily delectable substance (saccharin and water) gives them stomach pain, by simultaneously injecting them with a pain-producing chemical. Unexpectedly, this chemical also suppressed the immune system of the mice. The mice, of course, knew nothing about the effect on their immune system. Nevertheless, whenever they received saccharin after being conditioned, their immune system was suppressed even though the pain-producing chemical was not administered. While one can imagine the mice consciously associating saccharin and stomach pain, and their brains somehow sending signals that simulated pain, it seems inconceivable that the mice knew anything about their immune system.

Then along came chaos theory which implied that the flight of a butterfly in Brazil could, in principle, affect weather in Canada. In effect, a slight change in initial conditions could, in the fullness of time, have very large effects. Now, it is generally admitted that the solar system is chaotic after all. Each planet is subject to the tiny, butterfly-like gravitational tugs of the other planets, especially Jupiter. Given enough time, these gravitational nuances can result in the ejection of a planet from the solar system -- and may already have done so in the past! Mercury and Mars are the most vulnerable on a billion-year time scale. In the case of Mercury, its orbit will become more and more elliptical according to computer simulations. Eventually a close gravitational encounter with Venus is possible. This could send Mercury careening off into deep space. The probability of this happening is only 1 in a 1000 over 5 billion years, but it is not zero. Mars might likewise be ejected by a passing nudge from earth. However, this encounter could go the other way. Depending upon the celestial dynamics of the encounter, Mars might gravitationally fling earth out into the Galaxy, and ...

Science Frontiers ONLINE No. 47: Sep-Oct 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Unpredictable Things Simple spherical pendulums are fixtures of physics labs, to say nothing of grandfather clocks. It is now widely recognized that pendulums can behave chaotically; that is, unpredictably. As the pendulum bob swings farther away from its rest position, the restoring force becomes nonlinear; i.e ., not proportional to the displacement. At some combination of displacement and driving frequency, a region of chaos may develop, in which theory is powerless to tell what is going to happen next. "It is not just the behavior of pendulums that has sprung this surprise. Systems as diverse as simple electrical circuits, dynamos, lasers, chemical reactions and heart cells behave in an analogous way and the implications extend far beyond these examples -- to matters such as weather forecasting, populations of biological species, physiological and psychiatric medicine, economic forecasting and perhaps the evolution of society." (Tritton, David; "Chaos in the Swing of a Pendulum," New Scientist, p. 37, July 24, 1986.) Comment. Some of the anomalies we record may be the consequence of simple systems gone wild. Chaotic motions of some asteroids and at least one solar system moon are already suspected. Imagine what might happen in much more complex systems, such as biological evolution (hopeful monsters?), brain development (idiot savants?), etc. From Science Frontiers #47, SEP-OCT 1986 . 1986 ...

Science Frontiers ONLINE No. 98: Mar-Apr 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The earth has recently been swallowed by a cloud of inter-stellar gas Using cosmic-ray data and stellar spectra gathered by seven satellites, P.C . Frisch, at the University of Chicago, has constructed a cosmic scenario that reminds us of F. Hoyle's science fiction tale, The Black Cloud . According to Frisch, until just a few thousand years ago, the solar system was cruising through interstellar space that was almost devoid of matter. Then, perhaps within historical times, 2,000-8 ,000 years ago, the solar system plunged into an interstellar gas cloud. This cloud is believed to be the remnant of the bubble of matter shot into space perhaps 250,000 years ago by a supernova in the Scorpius-Centaurus region. This tenuous cloud of gas feeds matter into the solar system, some of which interacts with the solar wind and, therefore, affects the geomagnetic field, too. Climate changes may have been caused by entry into this cloud, and very likely the flux of cosmic rays impinging on the earth would have been modulated.

... a remarkable article. Even more remarkable is the fact that it has been published in a mainstream scientific journal. In fact, this contribution is full of statements guaranteed to ruffle the feathers of any rationalistic scientist -- and 99.9 % of all scientists are rationalistic. Take, for example, the first sentence of Winkelman's summary: "The correspondences between parapsychological research findings and anthropological reports of magical phenomena reviewed here suggest that magic is associated with an order of the universe which, although investigated empirically within parapsychology, is outside of the understanding of the Western scientific framework." As a consequence of this inflammatory tone of the article, the comments that follow are rather emotional in many instances. A philosopher could write another paper on the character and prejudices of the "scientific belief system" based on these comments alone! Enough of the controversial nature of Winkelman's article; what does it say? Basically, it states that many magic systems; such as sorcery, witchcraft, divination, and faith healing; may have originated and still be sustained by the psi abilities of the practitioners of magic. Psi here includes telepathy, precognition, psychokinesis, etc. The body of the paper reviews the characteristics of magic and the areas "correspondence" with parapsychology. Examples of areas of correspondence: altered states of consciousness, visualization, positive expectation, and belief. Indeed, the correspondences are strong; and this fact leads to the sentence from the summary quoted above. (Winkelman, Michael; "Magic A Theoretical Reassessment," Current Anthropology, 23:37, ...

... people claiming to have exceptional memories. In their second paper (Ref. 2), they detailed the mental workings of TM, a 25-year-old male, and an accomplished user of mnemonics. TM astounds audiences with his seemingly impossible memory feats. These feats, however, are no mystery to TM, and he has carefully explained how it is all mnemonics and nothing paranormal. But there remains the clear implication is that the normal human mind is underestimated and underused. TM's "performances" involve six demonstrations, two of which we now elaborate upon. Demonstration 2. TM asks audiences for birthdates and very quickly gives the day of birth. He has explained this "gift" thusly: "The day of birth calculations were originally carried out through use of a system of numerical codes for years and months which were combined and subjected to certain calculations. However, with practice many shortcuts and mnemonics have been developed and now TM often knows instantly that certain dates imply certain days, like learning the multiplication table. Every year and month has a code from 0 to 6 and TM has learned the codes (by the method explained below) for all years from 1900 to 2000. For any given date the method is to add the codes for the month and the year and divide the total by 7; the remainder gives the day of the week. For example, 27 October 1964 gives 27+ 1 (the code for October)+ 3 (the code for 1964) = 31. Dividing by 7 gives a remainder of 3 which is the ...

... why it is given space in Science Frontier. The reason is that we have a suspicion that it is all too easy, too simplistic. Could something more subtle be at work? After all, we really know next to nothing about the real workings of life-as-a -whole, its ups and downs. It is so easy to say that a group of organisms was done in by a temperature change or the fall of acid rain brought on by the impact of an asteroid. We always look for external forces, whereas the real cause of "crises" in the history of life may be intrinsic to life itself. With a tip of the hat to the Gaia hypothesis, let us think of life-as-a -whole as a most complex, interlinked system. What might be the dynamics of such a megasystem? From the mathematical point of view, many of the processes involved, as life copes with the environment, are doubtless nonlinear, which means that chaotic conditions may sometimes prevail. In fact, the graphs presented below could have been taken right out of a book on chaotic systems. Life's extinctions and explosions might have no connection to asteroids, Ice Ages, or global volcanism. If something as simple as a spherical pendulum can lapse into chaotic motion, life-as-a -whole should show occasional wild behavior, too. Take our planet's weather as another example. Idealists once thought that given enough observations and computer power, weather could be predicted. But, alas, our atmosphere has also turned out ...

... captured by the earth's gravitational field. Some of these would fall to earth; others would remain in orbit. Now, the reverse scenario has been investigated numerically. S.A . Phinney and colleagues at the University of Arizona have calculated what would happen to small chunks of the earth's crust if a large meteor impact excavated a 60milewide crater. "Phinney's group used a computer to calculate where 1,000 particles would go if ejected from Earth in random directions, moving about 2.5 kilometers per second faster than the minimum speed necessary to escape. Of the 1,000 hypothetical particles, 291 hit Venus and 165 returned to Earth; 20 went to Mercury, 17 to Mars, 14 to Jupiter and 1 to Saturn. Another 492 left the solar system completely, primarily due to gravitational close encounters with either Jupiter or Mercury that 'slingshot' them on their way." (Eberhart, Jonathan; "Have Earth Rocks Gone to Mars?" Science News, 135:191, 1989.) Comment. One implication from the preceding analysis is that terrestrial bacteria and spores could well have infected every planet in the solar system and perhaps even planets in nearby star systems! Conceivably, if other star systems had histories like ours, biological traffic might be quite heavy in interstellar space. In fact, extraterrestrial life forms may be arriving here continually; and we may be such ourselves! From Science Frontiers #63, MAY-JUN 1989 . 1989-2000 William R. Corliss ...

Science Frontiers ONLINE No. 71: Sep-Oct 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The bombardier beetle pulse-jet Creationists have long pointed to the bombardier beetle's jet-like defensive spray mechanism as a device that could not have evolved in many small steps. It must be complete and perfect to work at all. New high-speed photos and related research demonstrate that: "The ejection system of the beetle shows basic similarity to the pulse jet propulsion mechanism of the German V-1 'buzz' bomb of World War II." What the beetle has "evolved" is an intermittent explosive process that fires about 500 pulses per second. The explosive energy comes from the mixing of two separate fluids (hydroquinones and hydrogen peroxide with oxidative enzymes). (Dean, Jeffrey, et al; "Defensive Spray of the Bombardier Beetle: A Biological Pulse Jet," Science, 248:1219, 1990.) Comment. The fundamental question is, of course, how can many, small, random mutations contribute to the development of the mechanisms of the pulse jet, its two fuels, the pumps, the fuel reservoirs, the control system, etc., when only the complete, perfected system has survival value. Although creationists argue that the theories of evolution and natural section are unconvincing here; it is still possible that atheistic factors still beyond our ken are operating, and that what we really need is a better theory of evolution.
