At first the swarm is disordered. But after a minute, it breaks up into a set of concentric rotating rings. Within each ring, the balls follow one another along precise tracks, as if hugging the rim of an invisible roulette wheel. Soon the balls in each track are perfectly equidistant. Finally, one ball in each ring comes to a dead stop. The other balls in each track line up behind the leader in a tiny arc, even though the magnet is still whirling away below. Example 2. In water, large, fatty molecules (phospholipids) are observed to self-assemble into double layers with their water-loving bonds pointing outwards. This sort of structure closely resembles that of the biological membranes so vital to terrestrial life. This potentially biologically useful structure self-assembles!

In actuality, megalithic ruins of sorts are to be found almost everywhere. In Oceania, for example, we have the Latte Stones found decorating many of the Mariana Islands in Micronesia: "Looking a bit like immense bird-baths, the Latte are shaped like truncated pyramids (halenges) capped with enormous hemispherical stones (tasas). They range in height from 5 to 20 feet with circumferences of up to 18 feet and weights that have been estimated at up to 30 tons. The columns are found throughout the Marianas, usually in double rows of up to six stones." Are the Latte Stones burial monuments or, as some are convinced, merely supports for the dwellings important personages in ancient Micronesia? But why would anyone build a house 20 feet above the ground? Even the Micronesians scoff at the idea. Instead they attribute the Latte Stones to the taotaomona, the spirits of the "before-time" people! The Latte Stones are so old that even when Magellan discovered the Marianas in 1521, no one remembered what they had been used for.

Of course, such twins are genetically different, but they are still monozygotic (from the same egg). Blood tests will show them to be identical.

It was like a breath of fresh air to read this sentence in Sky and Telescope: "Scientists are still unable to confirm the existence of even a single black hole, despite a widespread belief that such things should, and indeed must, exist." This single sentence won't change anything, because everyone is comfortable with black holes. They are part of the (often false) reality that the media smothers us with. Actually, there are two places where black holes "might" dwell, based upon the anomalous behavior of matter around these regions: (1 ) at the centers of some galaxies, including our own Milky Way; and (2 ) as unseen components of some close double stars, where the mass of the unseen companion is too great for it to be an ordinary neutron star. W. Kundt and D. Fischer, at Bonn University, have recently concluded that the second possibility is better explained without resorting to black holes. For example, a neutron star with a massive accretion disk might suffice. As for black holes at the centers of galaxies, with masses of several million suns, gravitationally sucking in surrounding matter and careless spaceships - well, they are possible. Unfortunately, galac-tic centers are too far away and obscured by dust for us to be certain what lies at their cores. Black holes are really only surmise; although they make good copy!

What is the difference between "vanilla" and "chocolate" niobium? To begin with, these two forms of niobium are neither single atoms nor crystalline arrays of atoms. Both "flavors" of niobium consist of 19 niobium atoms (Nb19+ ), but the atoms are clustered differently, as illustrated. The different clusters react quite differently chemically. The "chocolate" niobium, on the right, is a capped icosahedron and reacts readily with hydrogen. The "vanilla" double pyramid (left) has flatter surfaces and does not readily combine with hydrogen. Cluster research is embryonic, with new surprises popping up almost every day. Once a cluster size exceeds a few hundred atoms, its properties begin to resemble those of the bulk material. However, "cluster-assembled materials" have been made by attaching clusterto-cluster in a sort of patchwork quilt. Such materials have unique properties that are quite different from those of the normal crystalline and amorphous materials. (Pool, Robert; "Clusters: Strange Morsels of Matter," Science, 248:1186, 1990.) Comment. One would expect that the effects of clustering would be important in biology, too.

Bednarik, in a recent paper in Antiquity, offers a related observation: "It is generally agreed that both regions have been settled from the north, yet no trace has been found of the first settlers in either North America or northern Australia. In northern Australia one finds groundedge axes at up to 23,000 b.p ., which have no counterparts in the probable catchment area of the first colonizers, Indonesia; while in North America the earlist human settlers used elaborate projectile points, which have no counterparts in the final Pleistocene of eastern Siberia. When and where did such innovations then evolve?" Bodnarik's aolution to this double dilemma assumes that the first colonizers in both cases did indeed come from the north-- -some 40,000 years ago in both Australia and North America - but that their invasion paths were confined to the low coastal areas. Then, as the Pleistocene ended and the ice sheets melted, the sea level rose to obliterate the signs of earliest occupation. Therefore, if archeological digs could be conducted under a few hundred feet of water along the continental shelves, the artifact gap could be filled!

The witnesses were adamant that the UFO did not look at all like a plane; and that it was much higher in the sky than planes on normal glide paths, which were to be seen just above the horizon between the houses. S. Campbell, who investigated this event, suggests that the Westgarths saw an enlarged distorted mirage of a Boeing 757 landing at Edinburgh. The timing and direction were right. Mirage action would elevate the image. By assuming that both an erect and inverted image of the aircraft were projected one above the other, something looking like a missile could be imagined. The black band would have been the doubled image of the wing. (Campbell, Steuart; "Mirage over Edinburgh," Journal of Meteorology, U.K ., 12:308, 1987.) Comment.

Meaden has recently summarized his research into those marvelously sharp and complex designs cut into English field crops by atmospheric vortices. (Why other countries are not similarly affected is unknown.) The simple circles range from 3 to 30 meters in diameter. The central, flattened vegetation is crushed clockwise about half the time, counterclockwise in the other cases. On two known occasions, the flattening process has actually been observed. The invisible atmospheric vor tex does its work in 30 seconds or less and generates a high-pitched humming sound. The complex nature of these vortices is attested to by the rare ringed circles and multiple patterns. Both single- and double-ringed circles are known. The wind direction always alternates from central circle to first ring to second ring. The most common multiple patterns consist of large central circles flanked by two or four, smaller satellite circles, all nicely spaced. In the quintuplets, all five circles are usually flattened clockwise, but one case has presented theorists with four counterclockwise circles accompanied by a single improbable clockwise circle!

As for the "discovery" of double-struck feathers in the Archaeopteryx fossil, which Hoyle thinks were the result of inexpert forgers, Nield remarks that these were noted by naked as long ago as 1954, and are due to two rows of slightly overlapping feathers with faint "through-printing". And while it is true that the two halves of the fossil studied by the Hoyle group are not perfect positive-negative pairs, this is but an artifact due to the complexity of the break.

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. This nudging periodically sends a large shower of comets careening around the inner solar system. The earth intercepts one or more of these projectiles each visit and -- bang -- we have new craters and another biological catastrophe.

This is not a large amplification factor by laboratory standards, particularly for a CO2 laser. But, the authors speculate that the sheer size of the natural lasers could make them useful tools in the future for communicating with distant civilizations beyond our own planetary system." The atmospheres of Mars and Venus are almost pure CO2 . The CO2 molecules are excited by the absorption of energetic solar photons; then, thermally emitted photons at about 10 micrometers from lower reaches of the atmosphere collide with the excited molecules, stimulating them to emit another 10-micrometer photon, thus doubling the number of photons. This is typical laser action. Deming and Mumma speculate that the natural laser action existing in the Martian atmosphere could be intensified and focussed into an intense beam of infrared radiation of enormous power by placing two large mirrors in orbit, creating a space-borne analog of a laboratory laser. With this huge laser, one could conceive of communicating with neighboring stellar systems. (Taylor, F.W .; "Natural Lasers on Venus and Mars," Nature, 306:640, 1983.)

... . Yet, there is no agreement as to its mode of origin. One might say that planetary scientists have just about thrown in the towel on the three major theories of lunar origin. Two recent articles attest to this discouraging situation. A Sky and Telescope article provides an excellent review of all three theories, indicating the reasons why each fails to convince a majority of scientists. The theories and the primary reasons for their rejection are: (1 ) Fission from earth . Lack of sufficient angular momentum in the earthmoon system and the fact that the moon does not orbit in the plane of the earth's equator. (2 ) Gravitational capture . The capture of such a large object in a nearly circular orbit is considered too improbable. (3 ) Earth-moon accretion as a double planet . The compositions of the earth and moon are too different. This article concludes that the resolution of the problem of lunar origin must await our return to the moon for more scientific exploration. (Rubin, Alan E.; "Whence Came the Moon?" Sky and Telescope, 68:389, 1984.) An article in Science also discusses the classical theories of lunar origin and quickly disposes of them for the above reasons. However, a fourth theory makes an appearance, which we might call the Big Splash Theory.

Science Frontiers ONLINE No. 10: Spring 1980 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Double hubble: age in trouble A key concept in modern astronomy -- the distance scale -- has been challenged by a new measurement technique. In recent years, the so-called Hubble Constant has been used to determine the distances of the farthest observable galaxies and, by assuming that they are near the periphery of the expanding universe, obtaining the age of the cosmos by dividing distance by the speed of light. Until this current challenge, the age of the universe was generally taken as about 20 billion years. The "old" Hubble Constant, however, was determined from the measurements of the distances to rather close galaxies and then assuming that the Constant thus derived held for the entire universe. The new yardstick reaches farther out into space. It is based upon the observation that the broadening of galaxy's 21-centimeter radio emission depends upon its rate of rotation, plus the belief that the rate of rotation is proportional to its brightness! This "new" Hubble Constant is 95 kilometers/second/ megaparsec, which translates into an age of only 10 billion years for the universe. Both the 10-billion-year and 20billion-year camps claim strong supporting evidence for themselves and also point to serious difficulties in the opposing method. The stage is thus set for a delightful controversy. (Hartline, Beverly Karplus; "Double Hubble: Age in Trouble," Science, 207: 167, 1979.) ...

Two of many cosmoseisms felt during the meeting in Poland are recorded below: "Halton Arp, Max-Planck Institute for Astrophysics, spoke about his "Variable Mass" cosmology. He pointed out the need for cosmologies to explain why quasar redshifts cluster near 0.3 , 0.6 .. ., with the grouping just below z = 1.2 dominating all others; and why certain classes of stars have significant excess redshifts. He also pointed out the inconsistency that local galaxy groups seem to have velocity dispersions of less than 100 km/s , while distant groups seem to have members with dispersions up to 1000 km/s . "Jack Sulentic spoke about multiple redshifts seen in some quasars and AGNs. Line profiles come in all types; symmetric, double-peaked, and asymmetric. Relative shifts are both toward the red and the blue. Arguments against an accretion disk/black-hole model were reviewed. Apparently a non-Doppler redshift-blueshift mechanism is needed. For example, one broad line (in 1404+ 28) shifts back and forth by 1000 km/s relative to another narrow H-line, with an average offset of 2000 km/s . These shifts correlate perfectly with intensity." Less technically speaking, the longheld belief that redshifts are solely due to the Doppler effect is receding along with the expanding universe!

The current consensus holds that wind is the motive force, but that it is inadequate to move the rocks directly. Instead, the wind acts upon sheets of ice in which the rocks are frozen. As these sheets of ice are moved across the playa, the keels of the frozen-in rocks leave those curious trails that have intrigued Forteans for many decades. (SF#109) Playa sliders have also been found at Magdalenasmeer Playa in South Africa, and in Nevada and Tunisia. In a recent issue of Geology Today, C.C .

Perhaps he should have written "times", for the various portions of the universe we can see through our telescopes may be moving along different "time lines" -- on different schedules, so to speak. According to W.G . Tifft, we may have to replace our concept of one-dimensional time with three-dimensional time if we are to explain some pressing cosmological anomalies. Redshift differences of double galaxies. The horizontal axis is the redshift difference in kilometers/second. The vertical axis is the number of pairs having a given redshift difference. It all began about 1970 OTL (Our Time Line!), when Tifft showed that the redshifts of galaxies are quantized. To illustrate, the diagram indicates that the redshifts of binary galaxies tend strongly to cluster at 72 and 72/3 kilometers/ second. One would certainly not expect ponderous galaxies to orbit one another in a quantized fashion. It is almost as if binary galaxies emulate those dumbbell-shaped molecules that can spin around only at specific frequencies! Can the mechanics of the very large (galaxies) be quantized like the very small (atoms and molecules)? Tifft obviously thinks so: "Quantization, it seems, is a basic cosmological phenomenon. It must reflect some master plan." The Finnish physicist, A. ...
