Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, and the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide. For nearly a century, geologists have been trying to resolve this Mechanical Paradox. Three potential solutions have been proposed: (1 ) Lubricate the sliding surfaces with water under high pressure (the pore-pressure approach); (2 ) Allow the thrust block to slide, not as a unit, but in small discrete areas at different times (the dislocation approach); and (3 ) Push the thrust block not only from the rear edge but along the top surface (the tapered wedge approach). In fact, all three solutions may apply; but there is no consensus so far. Each solution has problems.

Einstein provided an explanation of aberration in his famous 1905 paper using his new relativity theory, and his explanation remains essentially without modification in many modern textbooks.

The essence of Prof. Hayden's main argument is that, if stellar aberration depended on the relative velocity between source and observer (as Einstein maintained), then each component of a spectroscopic binary star would have drastically different stellar aberration, contrary to observation.

Did the old navigators sail into these now-frigid waters and map this great southern continent? One way to answer such questions is by turning to old maps and, then, asking the geophysicists if most of the continent's ice cover could have disappeared fairly recently, as some ancient maps are purported to show. C.P . Hapgood, well known for his book Maps of the Ancient Sea Kings, believed that ancient mariners did indeed map Antarctica when those climes were warmer. More recently, J.G .

Now, D.C .Jolly has put the whole problem in perspective in an excellent review. Jolly has studied the data in depth, as indicated by his 51 sources. In his view, it boils down to the fact that the old maps, which people of all persuasions use, are often incomplete and ambiguous. One can read a lot into them. 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.

In dairy-farming societies, 90% of the population has the enzyme lactase that allows individuals to digest cows' milk. In other societies, 80% become ill when drinking cows' milk. A variety of cultural pressures have raised the percentage of lefthanders in North America to 12% compared with just 2% a century ago. In Taiwan, where cultural pressures are quite different, only 1% of the populace is left-handed. In the end, of course, neither genes nor memes are in total control.

Thirteen years ago, Spiegel participated in a short-term program in which group therapy was given to 86 patients with advanced breast cancer. The goal was simply to make the patients feel better and "face their mortality." The result was that the patients became less anxious, less fearful, and more positive.

These signals consisted of a fundamental tone and evenly spaced harmonics. Sometimes, the fundamental tone rose and fell. This "natural trombone" was thought to be a gas-filled subterranean cavity capped at the top by rock, with a pool of magma at the bottom. Volcanic vibrations resonated in this chamber. As the magma pool rose and fell, the fundamental tone changed. More recently, a network of seismic stations in French Polynesia has picked up more mysterious seismic signals. These differ from those in Java in that each fundamental tone is "pure"; that is, there are no harmonics. Dubbed "T -waves," the sounds originated from an active volcanic ridge in the South Pacific. Suspicion fell on one flat-topped volcano that rose to within 130 meters of the ocean surface. But, how could this peak generate such a pure tone? The theory is that the active volcano spews out a column of steam bubbles bounded at the bottom by the flat volcano and by the ocean at the top. Computer simulations proved that sound could resonate in a column of bubbles just as it does in an organ pipe. Since the height of the column remains fixed, so does the fundamental tone.

If so, where did all the antimatter go? We assume we observe a universe that is virtually 100% matter. Of course, we cannot really tell for certain because an antimatter galaxy would appear to us just like a galaxy composed of ordinary matter. The only clues revealing substantial pockets of antimatter would be the annihilation radiation produced where matter and antimatter regions rubbed against one another.

When excavations were made around the Greek pyramids in the early 1900s, pottery fragments from the Fourth Century B.C . were found, and it was presumed that the pyramids were also constructed then; that is, about the time of Alexander the Great. Recent dating of crystals from internal surfaces of the limestone blocks using thermoluminescence puts the construction times back two millennia.

It is very clear that these so-called "idiot savants" use a variety of mental techniques, all rather different from rote memory, such as employed by memorizers of pi. First, we present Howe-and-Smith's abstract; then, a particularly interesting specific case. "A number of mentally handicapped individuals are able to solve difficult calendar date problems such as specifying the day of the week for a particular date, sometimes over spans of more than 100 years. These individuals are self-taught and do not follow procedures at all similar to the usual, published, algorithms. An investigation of one individual revealed that he retained considerable information about the structure of days in particular months, probably as visual images. His skill closely depended on the extent and form of his knowledge of calendars, and his errors were often a consequence of lack of knowledge about a particular time period. Mentally retarded individuals who perform calendar date feats are often socially withdrawn and devote considerable periods of time to calendar dates. The most capable calendar-date calculators are usually individuals who have a strong interest in calendars as such." Although some calendar calculators may use visual imagery - perhaps something like eidetic imagery - at least one calendar calculator was ...

It is hard to say. Who has followed hungry snakes around checking on their electric fields? A clue may lie in the ways snakes use their forked tongues in hunting. When following a chemical trail, snakes usually touch surfaces with their flicking tongues. In general exploration, when chemical trails are absent, snakes seem to wave their tongues up and down in a distinctive manner, avoiding surfaces. Herpetologists usually ascribe this action to chemical "sniffing." However, W.T . Vonstille and W.T .

A person would feel weightless in both situations. But the strange part arises when one looks at the two situations from the perspective of quantum mechanics; that is, one puts gravity into Shroedinger's equation. Ahluwalia asserts that the particle's (or person's ) gravitational presence is smeared out, just like that of the electron outside the solenoid. In consequence, masses can "feel" their gravitational potential and will behave differently in free fall than when inside a hollow sphere, contrary to what Einstein maintained in his General Relativity.

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.

Since redshifts are supposed to be a measure of distance from the earth, an anomaly comes into focus. This anomaly; that is, the credibility of the redshift distance scale, challenges the ideas of an expanding universe and the Big Bang itself.

One would have to invoke an enormous conspiracy of galaxies to avoid this conclusion. Yet, if accepted, this case alone brings into question the interpretation of cosmological red-shift for all galaxies."

Large impact craters occur in swaths. Although this has been suggested before, Shaw has mapped out several swaths where large craters of about the same age are located. His "K -T swath" includes the Chicxulub crater (Yucatan), the Manson crater (Iowa), the Avak crater (Alaska), and three more in Russia -- all of which were gouged out about the time of the Cretaceous-Tertiary (K -T ) boundary.

Shaw hypothesizes that nonlinear gravitational effects channel asteroids and comets into the inner solar system in intermittent bursts. The bursts are then captured by the earth and other inner planets, with some of these objects grouped in like orbits. Gravitational feedback occurs from earth to orbiting debris. Shaw believes that the uneven distribution of mass inside the earth -- due probably to the impact that created the moon -- influences where asteroids and comets impact. In turn, these large objects keep smashing into the same regions and their cumulative effect contols the flow of material inside the earth. Then, this change in mass distribution feeds back to change orbits and impact swaths. The above is just a taste of what is revealed in Shaw's ...

Impact-heating by meteorites or asteroids probably fused the famous slabs of Libyan Desert Glass and also the Darwin glass found in Australia. More curious are the peculiar glassy clinkers of fused wood ash found in hollow snags in trees after intense forest fires. This is called "combustion metamorphism." Combustion metamorphism is also common where undergound coal seams have caught fire and burn for decades. Humans get into the act, too. The ancient Scots piled up trees around their rock forts and fused the stones together with fire. (Why they bothered is unknown.) However, a different sort of natural glass has been found in east-central Botswana. There, archeologists have found 5-inch-thick layers of glassy slag interleaved with ashy soil in ancient middens (garbage dumps). These middens are not associated with pottery kilns or iron smelting. It is hard to imagine what could have melted layers of garbage, including pottery, plant material, and other biomass. Analysis of the slag indicates that temperatures of 1155-1290 C were required to fuse the garbage. Open fires could not have attained the necessary temperature.

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.

He then reconsiders his action, evaluates it, worries about it, feels good or bad about it, makes resolves about future decisions, and so forth.

A pertinent line of brain research is now underway at the Coleman Laboratory of the University of California in San Francisco, where Michael Merzenich and his associates are studying the brains of monkeys. "Merzenich's findings challenge a prevailing notion that most sensory pathways in the nervous system are 'fixed' or 'hardwired' by the maturation of anatomic connections, either just before or soon after birth. They also address the puzzling question of what forces may be at work when stroke victims partly recover. Do 'redundant copies' of skills exist outside the damaged regions, or is physical damage within the brain repaired over time? Or can old skills be newly established in different, undamaged brain regions." Apparently the brain should really be compared with a reprogrammable computer. Perhaps the brain even stores duplicates of critical "programs"; i.e ., skills. Merzenich's findings go even farther. He finds that the parts of the brain associated with certain skills or data processing move and change shape spontaneously. The brain, it seems, continually reorganizes itself. Fading fast is the idea that each data point is recorded in a specific cell or neuron interconnection. (Fox, Jeffrey L.; "The Brain's Dynamic Way of Keeping in Touch,: Science, 225:820; 1984.)

... high esteem that cosmologists commonly accord it." We have neither the space nor the expertise to lay out before you the details of the new Burbidge-Hoyle-Narlikar cosmology. Suffice that it involves black holes residing in galactic centers performing as "minicreation" centers, thereby replacing the one-time Big Bang creation event. The aspect of the new theory that amazes the most is the acceptance of the Arp heresy: that some quasars possess intrinsic red shifts not associated with the expanding universe. They write: "Nonetheless, observations over many years have accumulated good statistical evidence that many high-redshift quasars are physically associated with galaxies with very much smaller redshifts." So, at least some prominent scientists accept Arp's conclusions. (Burbidge, Geoffry, et al; "A Different Approach to Cosmology," Physics Today, 52:38, April 1999.) Comment. "Minicreation events"?

Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Caenorhabditis Elegans The creature with this formidable name is only about a millimeter long and develops from egg to adult in about 3.5 days, at which time it possesses about 1,000 somatic cells. C. elegans is a roundworm, but a famous one. Its growth has been followed on a cell-bycell basis from egg to adult. The history of each cell is known from birth to death. The fact that C.elegans is nicely transparent helps the cell-watcher. Here are some of the interesting things to be seen as cells proliferate, live, and die. First, C. elegans is bilaterally symmetrical, but the pattern of cell generation on the right differs from that on the left. Nevertheless, the creature ends up symmetrical, making one wonder where the directions for symmetry come from. Some cells are transients, dying when their jobs are done. A few doomed cells are generated only because they produce sister cells that are needed in the final animal. Such a programmed loss of cells may be a method of modifying an organism during evolution. John Sulston, one of the researchers, says, "Within the lineage you can see the fossil of its past." (Marx, Jean L.; "Caenorhabditis Elegans: Getting to Know You," Science, 225:40, 1984.) Comment. Sulston's statement reminds one of "Ontogeny recapitulates phylogeny," which we thought had been discredited long ago. From ...

Manning and his colleagues decided to see if there is a link between human hand shape and fertility. There is! Men with hands that are not precise mirror images of each other tend to produce fewer sperm. Manning asserts, "The more asymmetry, the fewer sperm." Easier to test yourself are the relative lengths of your ring and index fingers. Men tend to have ring fingers that are longer than their index fingers. The greater this difference in males, the higher their levels of testosterone, a hormone associated with fertility. In women, the same fingers are usually about equal in length. However, in contrast to males, larger index fingers are correlated with the increased presence of fertility hormones, such as estrogen and lutenizing hormones.
