Like us, they think that final knowledge is at last within reach. Like us, they pity the people in earlier ages for not knowing the true facts. Unfailingly, human beings pity their ancestors for being so ignorant and forget that their descendants will pity them for the same reason." E. Harrison, who penned the above, sees knowledge as perpetually uncertain and always changing. Scientists will always be surprised, he says, and scientific laws are never final. He concludes: "I feel liberated by this philosophy. I find comfort in the thought that the creative mind fashions the world in which we live. For it means that the mind and reality are more profound than we normally suppose." (Harrison, Edward; "The Uncertainty of Knowledge," New Scientist, p. 78, September 24, 1987.)

... scientific observations. At Norberg, in central Sweden, a huge deposit of magnetite creates a powerful magnetic anomaly. The deposit is 12 kilometers long by several wide. At low altitudes, the total magnetic intensity of the earth's field is 60% higher than normal. What happens when migrating birds fly into this magnetic bump? "Although Almerstam found that many migrating birds showed no signs of avoiding the Norberg anomaly, and often managed to keep on the right course as they passed through it, there were definite indications that the birds' orientation might be affected under special circumstances. Some migrants flying at low altitudes, where the magnetic intensity was greatest and the inclination and declination distorted greatly, became disoriented briefly. They nervously landed and then circled around before taking off again. Other birds changed their altitude abruptly, dropping 100 metres in two minutes and breaking up their flock formations." Certainly something is happening, but no one knows what. (Anonmous; "Magnetic Anomaly Upsets Migrating Birds," New Scientist, p. 32, November 5, 1987.)

The bush in the 1986 photos was still there; the Yeti wasn't ; the snow was somewhat deeper. Wooldridge and some companions took more pictures of the site: "Stereo pairs of photos taken in 1987 have been used to produce a threedimensional map of the terrain near the bush. When this is used to derive an absolute scale for pairs of photos from 1986, it shows that, whatever I photographed in 1986, lies below the snow level in the 1987 photos. The object is leaning slightly uphill, and no movement can be detected when comparing photos taken at different times in 1986. The apparent change in position relative to the bush in some photos taken from different camera positions is caused by parallax. This evidence demonstrates beyond a reasonable doubt that, what I had believed to be a stationary, living creature was, in reality, a rock." (Wooldridge, Anthony B.; "The Yeti: A Rock After All?"

This subject of solar variability (in both diameter and period of rotation) has been long debated. Some early measurements of solar diameter, begun at Greenwich in 1830, seemed to some to show a steadily shrinking sun, but others found cyclic patterns. E. Ribes et al have just presented some data on solar diameter actually taken during the Maunder Minimum. "By analysing a unique 53-year record of regular observations of the solar diameter and sunspot positions during the seventeenth century, we have shown for the first time that the angular diameter was larger and rotation slower during the Maunder Minimum." A larger sun might be cooler, providing less heat, thus accounting for climate changes.

When photographed, these phenomena appeared as irregular blobs of light. Primarily there were two types of events: small shortlived, highly kinetic lights (' doves') and more persistent coronal type displays that were situated primarily over the apical structures of the church. More detailed descriptions of the phenomena, such as visions often occurred as 'flashes'; their details usually reflected the religious background of the experient.

Kimura has been promulgating what he terms The Neutral Theory of Evolution. He concludes that "the most prev-alent evolutionary changes that have occurred at the molecular level, that is in the genetic material itself, since the origin of life on Earth are those that have been caused by random genetic drift rather than by positive Darwinian selection." Kimua maintains and can experimentally prove to some extent that the genetic material of all organisms changes rapidly and constantly. The genes change much more rapidly than scientists believed just a few years ago. We observe few if any changes at the phenotype level (organism morphology) because the overwhelming majority of these changes are neutral. They confer no significant advantage or disadvantage on the organism. In fact, Kimura and others have demonstrated that the fastest molecular evolution occurs in the least important genes. It is fastest of all in the pseudogenes or dead genes, which seem to have no discernable functions. In other words, the genetic engine is running, but the gears are in neutral! In Kimura's thinking, these molecular changes may eventually become important at the phenotype level if the environment changes or there is some other destabilizing influence.

One type of jellyfish, rather than swimming around with its pulsating bell on top, plunks itself upside-down on the bottom and uses its bell as a suction cup to anchor itself. It then shoots poisonous darts attached to strings of mucous at passing targets and reels them in. Some African catfish graze on algae on the undersides of water plants. They swim upside down all the time and display a reversed color scheme, being black on the bottom and light on top. Gould employs these three examples to argue that changes in animal behavior must have preceded the many changes in form, function, color, etc. that make upside down living profitable. In other words, the proto-flamingos tried feeding with their heads upside down; and it didn't work too well. But "nature" responded with a series of random biological changes, some of which were just what was needed for efficient upside down feeding.

We quote from the conclusion of J.R .

Supposedly isolated from their neighbors for hundreds of thousands of generations over a period of at least several million years, and significantly violating virtually every restriction of the Hardy-Weinberg equilibrium for the non-evolving population, these organisms, even by creationist standards, should have undergone significant and detectable changes. In reality all they show are moderate changes, primarily in two coat color characteristics for part of their population. To make things even worse, this species is known to have a highly variable coat-color polymorphism throughout its range. Thus, even the differences displayed appear to be easily accounted for by several mutations and a slight change in gene frequency for one or two loci, all occurring in a limited period of time. "If an organism such as the Kaibab squirrel is able to escape all but a few minor changes in coat color (and these of dubious survival value) given the supposed immense time of rather complete isolation and violation of the Hardy-Weinberg equilibrium, we must ask wherein lies the fault.

The transitional field is low in intensity and is typically non-axisymmetric. Geomagnetic impulses corresponding to astonishingly high rates of change of the field sometimes occur, suggesting that liquid velocity within the Earth's core increases during geomagnetic reversals." The time period required for the field to reverse was about 4500 years, as measured at Steens Mountain, Oregon. There were three periods of very rapid change (impulses), which hint at radical changes in the core. The average magnetic field at the earth's surface decreased to 20% of normal during the reversal. (Prevot, Michel, et al; "How the Geomagnetic Field Vector Reverses Polarity," Nature, 316:230, 1985.) Comment. The illustration reveals that the reversal was far from a clean 180 flip; there was much meandering. Just what was happening in the core during the reversal is a mystery.

The redistribution of water near the equator to ice at high latitudes alters the rotation rate of the crust and mantle of the Earth. If the sea-level change is sufficiently large ( 10 meters) and rapid (in a few hundred years), then the velocity shear in the liquid core disrupts the convective cells that drive the dynamo. The new convective cells that subsequently form distort and tangle the previous field, reducing the dipole component near to zero while increasing the energy in multipole components. Eventually a dipole is rebuilt by dynamo action, and the event is seen either as a geomagnetic reversal or as an excursion."

However, E.R . John and his colleagues have confounded such thinking. They have prepared metabolic memory maps of cats' brains using carbon-tagging. In this way, they discern which parts of the brains have been activated during the recall of an element of memory. Such experimentation has demonstrated that huge numbers of brain cells actively participate in the recall of a simple thought. John stated, "I thought we'd find maybe 20,000 to 40,000 cells involved in the learned memory....The shock was that it was so easy to see wide-spread metabolic change....The number of brain cells [between 5 million and 100 million] involved in the memory for a simple learned discrimination made up about one-tenth of the whole brain."

Central Oregon is geologically young and plastered with lava flows and cinder cones. It is like a sponge, with many cubic miles of holes, air channels, and open fissures. The air in this rocky sponge is usually on the move in response to changes in atmospheric pressure. The earth absorbs air during barometric highs and expels it during lows. In some spots the expelled air is captured to cool homes during the summer. In the High Cascades, though, the underground winds pose hazards to skiers by creating blowholes in the snow. These blowholes are actually mildly anomalous because they blow out a gentle 40 F breeze regardless of the barometric pressure. Some of Oregon's blowing caves also "breath" without re gard to barometric pressure. Also, the water wells north of Fort Rock Basin often blow for days during periods of high barometric pressure -- times when they should be taking air in.

It is in a manuscript of Lombardic origin, which contains the otherwise lost "De Cursu Stellarum" by Gregory of Tours (who lived about 538593 AD). This new source reiterates that Sirius was once a red star, leading Schlosser and Bergmann to speculate as follows: "Thus, Sirius B might well have changed from a red giant to the white dwarf as it appears today. However, the rapidity and smoothness of this transformation are quite unexpected, and its timescale is surprisingly short. Furthermore, no traces of catastrophic effects connected with such an event have ever been found. The only indication that something has happened is the somewhat higher metallicity of Sirius A, believed to have resulted from contamination by the giant's blown-off shell."

Is our knowledge of stellar furnaces fundamentally in error or are some of the solar neutrinos somehow removed from the stream of neutrinos bound for earth? Recent calculations by Hans Bethe have brought sighs of relief to all astrophysicists. Without going into all of the details, Bethe finds that the interactions of the electron-neutrinos emitted by solar thermonuclear reactions with atoms constituting the solar mass change a substantial fraction of them into muonneutrinos. Since our terrestrial neutrino detectors register only electron-neutrinos, we may really be seeing only a fraction of the total number of neutrinos being emitted by the sun. If Bethe's calculations turn out to be correct, he may have eliminated a Class1 anomaly. But at a price!

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.

The physicist behind this new research is E. Wolf, at the University of Rochester. His theoretical work was re-ported in the March 3l, 1986, issue of Physical Review Letters. There he showed how quasars and so-called "superluminary" astronomical sources might emit light with a spectrum that evolves as it travels through space. Scientists have always assumed that once light left its source its spectrum remained unchanged. But Wolf shows how spectral changes are "sort of coded into the light due to correlations in the source." Meanwhile, two of Wolf's colleagues have backed up his theory in the lab. The consequences of Wolf's work would in effect shrink the universe, because objects would not be as far away as we now calculate from their redshifts. The size of the universe might contract "by a factor of 100 or more," says Wolf. If this much deflation is accepted by other scientists (It could be quite a fight!), then the age of the universe will also shrink, since it is based in part on our observations of the outer fringe of the universe and the speed of light. (Amato, I.; "Spectral Variations on a Universal Theme,: ...

... intense activity was observed on the starboard side of the ship where the phenomenon appeared to stretch as far as the horizon. At this stage, it did not appear localized, just a mass of high-speed interacting bands of light. The effect is shown in the first sketch. As is usual on an 'all aft' ship, you become 'deaf' to the constant background noises, but I gradually became aware that the pulses of light seemed to match those of the main engine's throb, that is, about two per second. The radar (3 -cm radar, running on the 24 n. mile range), and the echo-sounder (indicating a water-depth of about 35 fathoms), were switched off in turn to see if any change was discernible, but there was not. "However, at about this time, the ship passed a localized revolving system, distance off appeared to be about 150 m. My impression was that of a catherine wheel revolving and casting out waves in an angular motion, as shown in the second sketch. How many spokes it had I'm not sure owing to the speed of the pulsations, but I think that there were at least three. If viewed from above, the system rotated in a clockwise direction wheeling itself along the ship's track. No central hub was visible, just a dark area devoid of activity. One or two systems were visible farther out to starboard." (Lakeman, J.D .; "Bioluminescence," Marine Observer, 56 ...

Science Frontiers ONLINE No. 49: Jan-Feb 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Moho Vicissitudes For a long time the Moho (Mohorovicic discontinuity) has been considered a stable plane dividing the crust from the mantle. It is at the Moho that seismic wave velocities change abruptly. There is something there, but no one knows just what. At the recent Second International Symposium on Deep Seismic Reflection Profiling of the Continental Lithosphere, a lot of doubts about the stability and character of the Moho surfaced. Under the North American Cordillera, which runs from Alaska to Mexico, the Moho is flat, continuous and oblivious to the faults, terrane plastering, mountain "roots," and the geological phenomena above it. In other areas, though, several Mohos are stacked up. Some Mohos are discontinuous, jumping from one depth to another. Others are strongly influenced by overhead geological structures. Gone is the neat, so simple Moho figured in all the textbooks. (Barton, Penny; "Deep Reflections on the Moho," Nature, 323:392, 1986.

... in the fossil record, which imply a frequent lack of transitional forms from one species to another. As Stanley asserts repeatedly in his interview, the fossil record is actually quite good in many places, despite the long-voiced claims of the gradualists that transitional forms do not exist merely because of the deplorable state of the fossil record. In physics the analogous phenomena would be: (1 ) The chemical elements and their isotopes (or an atom's energy levels); and (2 ) The lack of transitional forms. Straining the analogy still further, the evolution of one species into another simply means that life-as-a -whole moves from one quantized state to another. There need be no transitional forms, just as there are none when elements are transmuted or galaxies change redshifts (? ). Atomic physicists, long since mystical about this whole business, no longer try to explain what happens during a quantum transition. The only observables are the quantum states -- or species, if you will. Is life no more than a Table of Isotopes, defined once and forever by eerie quantum selection rules? Reference. Many of the anomalies in the fossil record are cataloged in ESB in: Anomalies in Geology. For a description of this book, visit: here . From Science Frontiers #50, MAR-APR 1987 . 1987-2000 William R.
