... 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 set of initial conditions leading to the first type of behavior, there was an infinite number of slightly different initial conditions that would lead to the second type of behavior. In other words, systems that we have long thought to be deterministic, like the motions of the planets, may be not only chaotic but indeterminate. Since Sommerer and Ott found their indeterminate system easily, we must face the possibility that the future behavior of just about everything is beyond our capability to predict, even with our best instruments and computers. Apparently the universe is built in such a way that exact science is impossible. (Sommerer, John ...

The major data source for such population studies is the record of pelt sales rather than actual field observations. Looking beyond such superficial information, researchers have discovered that the quantity of pelts offered for sale by the Indians depends upon the amount of time they can divert to hunting pelts. This, in turn, is affected by the abundance of food animals, such as moose and hares. It is food first and pelts second. Furthermore, when the plants consumed by hares are overbrowsed during periods of dense hare population, they defend themselves by generating resins and other compounds toxic or repellent to hares. Thus, the hare abundance cycle is affected by: (1 ) Plant defenses; (2 ) Indian hunting strategies; and (3 ) The lynx.

Already a slightly oblate sphere, the planet becomes successively a bit more oblate, then a bit more prolate, as illustrated. The amplitudes of these deformations are small, just a centimeter or so after big quakes. The tone or frequency of the quivers is just a few millihertz, which translates to periods ranging from 3-54 minutes. We doubt that the telestomping elephants mentioned under BIOLOGY can detect these quiverings. That the earth does indeed "ring" is old news. Geophysicist A.E .H . Love mentioned the possibility in 1911. It is also recognized that large earthquakes can set the earth to ringing (" quivering" is better). What is news is the discovery by N. Suda et al that our planet rings even when no major quakes are occurring, and no one yet knows why. Suda et al write: "The observed "background" free oscillations represent some unknown dynamic process of Earth." Suda and his colleagues detected these oscillations using a superconducting gravimeter, which they installed in a seismically-quiet place: Antarctica. The favorite explanation for the background oscillations is turbulence in the earth's atmosphere. Ocean tides and currents are also on the list as potential "bell-ringers."

Spurred by Chi-nese work, a network of observers has been set up in California in an earthquake-prone area. Most reports of strange animal behavior have been after-the-fact. Furthermore, the "strange behaviors" frequently turn out to be common during quake-free periods, but simply not remarked upon. Nevertheless, geophysicists did observe some clear-cut instances of animals super-sensitivity to quake phenomena. Studying aftershocks in the Mohave Desert in 1979, Donald Stierman and his colleagues often heard earthquake booms 4-l0 sec after feeling the shock and seeing their portable seismometers record the tremor. Two dogs nearby inevitably responded with a chorus of barking. Sometimes though, the human observers heard and felt nothing when the seismometers and dogs announced another aftershock.

... in this paper. Jupiter's moon, Io, exhibits an anomaly that seems to call for a radical explanation. Io's volcanos erupt with such violence that molten material is flung to heights of 250 kilometers. These outbursts proceed from caldera, and one is led to assume that normal volcanic action is to blame. Unfortunately for this simplistic idea, Io does not seem to possess low-molecular-weight substances, such as water, that could serve as a good propellant at reasonable temperatures. Sulphur is common, but its atomic weight is so high that temperatures exceeding 6000 K would be required to shoot matter out to 250 kilometers. Gold suggests that Io's volcanos get their firepower from electrical sources. He points out that Io short-circuits Jupiter's ring current periodically. Gold estimates that 5 million amperes flow through Io when it passes through the ring current. The energetic eruptions and caldera might therefore be electric-arc phenomena. The electrical energies available are sufficient to account for the observed outbursts. (Gold, Thomas; "Electrical Origin of the Outbursts on Io," Science, 206:1071, 1979.) Comment.

"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."

It has now been discovered that clay samples from the Cretaceous-Tertiary boundary also contain 0.36-0 .58% graphitic carbon. It is fluffy stuff and suggests that the planet was once covered by a thick layer of soot. Quantitatively, the soot layer is equivalent to the carbon in 10% of the earth's present biomass. The authors speculate that this soot was created by huge wildfires that consumed much of the earth's vegetation and perhaps fossil fuel as well. Terrestrial life was, of course, devastated -- just as it is in the currently popular "nuclear winter" scenarios. The end-of-the-Cretaceous soot is in fact, thicker and more widely spread than nuclear winter theories predict.

"They find that Danish sediments spanning the narrow boundary layer contain two amino acids, alpha-aminoisobutyric acid and isovaline, that are relatively uncommon in biological materials but abundant in the organicrich meteorites. They suggest that the body which collided with Earth 65 million years ago and left the telltale iridium residue may have been organic-rich, perhaps like a C-type asteroid or a comet. Such a possibility has interesting implications for the extinction and related atmospheric effects, and supports the idea that impact events could have supplied the Earth during a much earlier period with the raw materials for organic chemical evolution." Actually, the above quotation is pretty much in line with present mainstream thinking. Perhaps so, but Bada and Zhao identified two troubling anomalies. First, the amounts of amino acids found were surprisingly high. How could these complex molecules survive the searing temperatures engendered by high-velocity impact? Second, the amino acids may be abundant tens of centimeters above and below the K-T boundary clay containing the iridium, but they are virtually absent in the clay itself!

He hypothesized that all those sheets of unconsolidated rocky debris strewn across the planet--called the "drift" -- were the consequence of impacts of comets. But in Donnelly's day, all geologists were uniformitarians and wedded to glacial theory. Donnelly's "age of fire and gravel" was really a succession of Ice Ages. Quite a difference in mechanism! Glacial theory, however, has difficulty in explaining apparent glaciations during periods when the earth was supposed to be very warm. Nor does it account easily for glacial-like debris in equatorial regions. With the current ascendancy of "impact geology," some brave geologists are reinterpreting supposed glacial deposits in terms of sheets of ballistic ejecta from the impacts of comets and/or asteroids.

Archeologists are striving to save as much information as possible before the bulldozers destroy the best artifacts left by this remarkable Indian civilization. This beautifully illustrated article touches on several of the precocious and puzzling features of the Hohokam Period, circa 0-1 ,400 AD. (1 ) The Hohokam apparently employed acid-etching to produce designs on shells. Acetic acid from fermented cactus juice was use to eat away portions of the shell not protected by tar. (2 ) Four-story Casa Grande, which seems to have been an astronomical observatory, required at least 600 big wooden beams, all of which had to be transported over 50 miles from sources in the mountains. (3 ) The Hohokam built an elaborate, well-engineered system of irrigation canals. (4 ) Unexplained are many flat-bottomed oval pits up to 182 feet long, 55 feet wide, and 13-18 feet deep. Some surmise they were ball courts. (5 ) Also puzzling are rectangular earthen mounds, 75 x 95 feet at the base and 12 feet high, with flat adobe-covered tops.

... -told tales are truthfully no more convincing to a scientist than many UFO anecdotes. When carbon atoms danced through the dreaming brain of A. Kekule, they led the waking Kekule to conceive the structure of the benzene molecule. I. Lowe awoke from a dream one night, jotted down a few notes, and fell back to sleep. On waking, he could not decipher his scrawl. Happily, the next night the dream recurred. Lowe raced to his lab, performed the experiment outlined in his dream, and thereby developed a new theory of brain activity. In 1869, D. Mendeleyev was puzzling over the disparate properties of the 63 elements then known. Was there any pattern? One night he fell asleep and in a dream the elements fell into their proper places in the Periodic Table. (Mazzarello, Paolo; "What Dreams May Come?" Nature, 408:523, 2000.) Comments. These mammalian anecdotes involving sleep and dreams are amusing, but most dreams are frivolous, bizarre, and of very little practical value, Mendeleyev notwithstanding. The utility of sleeping and dreaming do not seem at all commensurate with the accompanying vulnerability and the loss of waking hours. However, speculation is fun. There are at least two rather far-fetched explanations for characteristics (sleeping and dreaming here) that do not appear to have very much survival value. Sleeping and dreaming may be linked genetically to a characteristic that does have considerable survival value. Example: Resistance to malaria is coupled to sickle-cell anemia. Sleeping and dreaming may represent unavoidable, intermediate ...

... , in the last 9 million years not only has the entire gorge of the Grand Canyon been cut but also a much greater volume of rock 300 meters thick adjacent to the present north and south rims. The immensity of the volume of sediment removed is not the real issue. The first problem emerges downstream from Red Butte at Pierce Ferry. There we find 200 meters of Hualapai limestone, which has been dated at 8.7 million years from a thin layer of volcanic ash within the limestone. When this limestone was laid down, the geology is emphatic that no large, sediment-carrying river was in the vicinity. Most geologists agree that the lower end of the Grand Canyon was not active around this time. No one knows where the Col-orado River was flowing at this period. Some say southwest from Peach Springs; others point to a northwest route into Utah. All the likely alternate routes face serious geological obstacles such as lava barriers. What does seem certain is that the stock explanation of the formation of the Grand Canyon is incorrect. It was not steadily ground out, cutting everdeeper as the whole region was slowly elevated. Actually, geologists believe that the region stopped rising over 50 million years ago. Where, then, did the sediments from a 450-kilometer canyon and the wide areas surrounding its rims go? The present exit of the Colorado near Pierce Ferry was blocked until fairly recently while the Hualapai limestone was being deposited; and other routes don't look too promising.

... exact a cost in the females, there might be an adaptive explanation for the phenomenon; that is, the final paler egg may lead to increased survival of the participating species. To illustrate, in 1980, Yom-Tov suggested that: .. .this last odd egg might have evolved as a signal to potential brood parasites that the female has finished laying the clutch and has begun incubation. If a parasite lays its egg after incubation has commenced, then it would be unlikely to hatch, hence the potential parasite would benefit from heeding such a warning signal, if it could then find an alternative host nest where incubation had yet to commence. The signaling host would also benefit from avoiding the costs of warming an extra egg [the parasite's ] for some of the incubation period, costs that can be considerable, as well as the possible cost of having to rear an extra chick. G.D . Ruxton et al have used game theory to show that Yom-Tov's speculation has considerable merit. However, there are nonadaptive explanations. The females in the species that lay pale last eggs may simply run out of egg pigment, or they may change physiologically as the egg-laying phase nears its end.

To claim an ice-free Antarctica, one has only to make a few assumptions. For example, one reduces the size of a map feature here and rotates another there. It seems that those old map-makers didn't get things quite right! Jolly is fair about the whole business and even admits his admiration for Hapgood. In part, his conclusions are: "Our knowledge of early cartography is limited, since much of the material from the sixteenth century is now lost. While this affords ample opportunity for speculation, there have been many scholarly studies of this period. These studies were not done by dunces, but by individuals who spent years acquiring the skills and perception necessary to interpret the evidence. Professor Hapgood, to his credit, spent almost ten years studying the evidence and consulting experts in the field. His ideas were rejected in scholarly circles not because of animus but because he had not proved his case. Too many leaps of faith were needed to establish his thesis. I fear it is impossible to be equally charitable toward some later advocates of the Hapgood thesis, whose methods do little credit to his memory."

Dodwell has analyzed the observational records com-piled for the many gnomons erected all over the civilized world during the past 4,000 years. Gnomons are vertical markers that cast shadows from which the local latitudes can be computed. (All one needs are the measurements of the shadow lengths on the longest and shortest days of the year.) The earth's tilt or obliquity-of-the-ecliptic may also be calculated from gnomon data -- and therein lies the anomaly. The tilt of the earth's axis is supposed to vary cyclically between 22 and 24.5 over a period of some 40,000 years due to the pulls of the moon, the sun, and the planets on the earth's equatorial bulge... Tilt angles computed from ancient gnomon observations deviate markedly from the theoretical curve. The alignment of the ancient Egyptian temple at Karnak and other oriented sites extend the deviation toward the date 2345 B.C . Either the ancient observations were systematically in error all over the world or the earth's tilt angle changed in historical times. (Bowden, M.; "The Recent Change in the Tilt of the Earth's Axis," Pamphlet No. 236, July 1983. Creation Science Movement.) Comment.

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. Several astronomers have been trying to pin down the properties of this Planet X or Massive Solar Companion (MSC). John P. Bagby has recently published a novel solution to this nagging puzzle in celestial mechanics. He suggests that the Massive Solar Companion is actually a distributed system; that is, appreciable mass also occupies the several stable Lagrangian points. The total MSC mass might be as much as half the sun's mass, perhaps 100 Astronomical Units (100 times the earth's distance from the sun.) If the MSC and its attendants are this massive, astronomers will have to revise the mass and density of the sun downward by a good bit. (What they have done in the past is estimate the mass of the solar system as a whole and assumed it mostly resides ...

... though not necessarily a causeeffect relationship -- your life span may depend on the number of sunspots that appeared in the year your mother was born. "They found that if the sun was at a maximum in its 11-year cycle (during which the number of sunspots rises and falls), children of mothers born at that time would die an average of two to three years sooner than if their mothers had been born during the sunspot minimum." Before dismissing this fascinating correlation as "nut science," consider that the study was conducted by two established scientists at Michigan State University, B. Rosenberg and D.A . Juckett. Their report was published in the March 1993 issue of the mainstream journal Radiation Research . Furthermore, in two English studies of longevity. the same periodicity was remarked. Although the population sample in the Michigan State work was small (7552), the phenomenon appears sufficiently robust to admit to the columns of Science Frontiers! (In truth we covet bizarreness as much as robustness!) But what possible causal link might connect one's longevity with one's mother's date of birth? Rosenberg and Juckett point to the fact that when a woman is born all of her eggs are already formed. Later, they will mature and be released one at a time (usually). Therefore, if solar radiation levels (proportional to sunspot numbers) are high near her time of birth, her entire inventory of eggs will be bombarded by high levels of solar radiation. The ensuing damage might show up as shortened lifetimes for her ...
