Two amusing examples are: The size of a planet is roughly the geometric mean of the size of the universe and the size of the atom; and The mass of man is the geometric mean of the mass of a planet and the mass of the proton. Less hilarious is the observation that the age of the universe is of the order of the quotient of the electron time scale and the gravitational fine structure constant; and that only at the present time are physical conditions in the universe favorable to the existence of life-as-we-know-it! The surprising number of coincidences that have been identified suggests that we exist and are aware of the universe around us only when certain coincidences prevail among physical constants. Is "now" a magic moment in the history of the universe during which we have "happened" as a natural coincidence of blindly drifting physical constants, or did some metaphysical force tune the universe specially for us?

"This article presents a meta-analysis of experiments testing the hypothesis that consciousness (in particular, mental intention) can cause tossed dice to land with specified targets face up. Seventy-three English language reports, published from 1935 to 1987, were retrieved. This literature described 148 studies reported by a total of 52 investigators, involving more than 2 million dice throws contributed by 2,569 subjects. The full data base indicates the presence of a physical bias that artifactually inflated hit rates when higher dice faces (e .g ., the '6 ' face) were used as targets. Analysis of a subset of 39 homogeneous studies employing experimental protocols that controlled for these biases suggests that the experimental effect size is independently replicable, significantly positive, and not explainable as an artifact of selective reporting or differences in methodological quality. The estimated effect size for the full data base lies more than 19 standard deviations from chance, while the effect size for the subset of balanced, homogeneous studies lies 2.6 standard deviations from chance. We conclude that this data base provides weak cumulative evidence for a genuine relationship between mental intention and the fall of dice."

These are true symbionts that feed on food scraps. The sizes and shapes of these invaders are neatly adapted to the mouths and cavities of each host. It is possible, but not easy, to explain how these remarkable physiological and behavioral transformations were initiated and perfected via random mutations and natural selection.

The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R . Johnson, is the northeastern Bering Sea, where sensitive side-scanning sonar has sketched large numbers of pits and furrows in the shallow sands. The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried organic matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C.

We are talking 50-foot sharks and larger here; sizes that make the hero (or heroine) of the Jaws series seem minnow-like. All of these hints come from the Pacific and focus on the possible survival of the shark Carcharodon megalodon , a monster relative of the great white shark. Megalodon is thought to have met its demise a million or so years ago. The word megalodon means "big tooth," and indeed the fossil teeth of this monster approach 6 inches in length. Sharks sporting teeth of this size could be as long as 50 feet. Measurements of the manganese dioxide layers accumulated on megalodon teeth dredged up from the seafloor suggest that it might actually have survived the Ice Ages and terrorized the Pacific as late as 10,000 years ago. Actually, some unfossilized teeth 5 inches long have been brought up by dredges, implying an even more recent existence. Do scuba divers have anything to fear today? There are rare reports of huge versions of a shark resembling the great white but without the high dorsal fin.

... Mimicry In Cuckoos In Britain, cuckoos mainly parasitize five species of smaller birds. They do this by laying their eggs in the hosts' nests. After hatching, the young cuckoos grow much faster than the young of the host species. Soon the cuckoo is able to eject the host's young from the nest and get all the food brought by the parents. Actually, the cuckoo is so aggressive in this business of parasitization that, when it finds a host nest with eggs so far along in incubation that parasitization is impractical, it destroys the whole nest. This usually forces the host birds to lay fresh eggs, giving the cuckoo a chance to parasitize the nest. The most remarkable thing about cuckoo parasitism is the birds' ability to match the eggs of the host species in size, spottedness, background color, and darkness. The eggs of all five species commonly parasitized in Britain are much smaller than a bird the size of the cuckoo would normally lay; but the cuckoo still manages to lay eggs of just the right size. When the bona fide eggs of the five parasitized species are placed side-by-side with the mimics layed by the cuckoos, the matches are uncanny - except in the case of the dunnock, which the cuckoo doesn't try to mimic at all. The question, of course, is how the cuckoos do it. American cuckoos rarely parasitize the nests of other birds; but the American cowbird is notorious in this regard, although it does not indulge in egg mimicry.

One of the more popular possibilities is that vast sea of neutrinos pervading the cosmos -- if they really do display just a hint of mass.

Anyone familiar with the writings of Hoyle and Wickramasinghe can guess what these nanometer-sized particles might be: viruses, of course!

"It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age."

Artist's concept of the Belgium Flying Triangle, with three white lights on the corners, one red light in the center. (From: Télérama , February 21, 1990.)

The object sometimes hovers for minutes at a time. It also can move very slowly and then suddenly accelerate to high speeds. Some observers report a faint humming sound; others say that it is noiseless. The American Stealth fighter (Fll7) is roughly triangular, and there has been much speculation that people have been seeing this craft on night missions.

Now, quasar 4C29.45 comes along and pulsates on time scales of 30 minutes and less. These pulsations are sharp and not spread out timewise, implying that quasar 4C29.45 must be smaller than 30 light-minutes in size -- otherwise the disturbance causing the pulsation would have to travel faster than light. On the night of April 10, 1981, the situation (already bad) worsened, when brightness jumps of 0.2 magnitude occurred nearly instantaneously.

But, at the 1997 spring meeting of the American Geophysical Union, Frank presented new data to back up his previous assertions. The most startling of his new evidence came from a camera aboard a NASA satellite. Time-lapse photos imaged two objects streaking into the atmosphere over Poland and Germany.

The balls swarm around inside the plastic dish as the magnet rotates. 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.

Nevertheless, we can and must wonder how its orbit became so badly distorted. Often in past years, whenever astronomers detected cometary orbits gone awry, they invoked Planet X; that is, some undiscovered massive body plying the outer reaches of the solar system. 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. Gladman proposes that 2000 CR105 was forced into its present eccentric orbit by an encounter with a Mars-size Planet X that now orbits the sun at a distance about 15 times that of Neptune. From the standpoint of celestial mechanics, this perturbation of 2000 CR105's orbit is certainly within the realm of possibility. But two associated problems worry astronomers: (1 ) The accepted theory for the formation of the solar system does not countenance the formation of planets the size of Mars so far away from the sun; and (2 ) If this newly postulated Planet X truly exists, why has it not ejected more 2000 CR105s from the well-populated Kuiper Belt over the billions of years Planet X has been perturbing the Belt ?

This sounds like so much physics-speak; but, seriously, during the birth pangs of the universe, there seems to have been what cosmologists call a "phase change," a mysterious moment when the laws of physics suddenly became more complex. You can reasonably ask: "How can supposedly immutable physical laws change?" The answer seems to be that anything can happen when something is being made from nothing! This apparent plasticity in the laws governing the cosmos is suggested by observations of how galaxies in the early universe were distributed. The standard theory for the origin of the universe predicts that clumps of galaxies of all sizes were created early on. This is not what a survey by S. Sarkar et al, at the University of Oxford, found. A split second after the Big Bang, galaxies were organized in structures about 300-million light years across. The standard model of particle physics cannot account for this preferred size. The theorists' recourse is a phase change, a point in time when the warp and woof of the universe changed; that is, change the rules until they fit.

For example, one scene painted on the tomb of one pharaoh represents tributes brought from afar to Egypt, including a parade of exotic animals. One of these animals is an obvious bear. This animal would have intrigued the pharaoh because bears and ancient Egyptians did not coexist. Just as exotic to the pharaoh would have been the miniature elephantid following just behind the bear in the painting. It was about the same size as the bear. Since this elephantid was depicted with large tusks, it was definitely not an immature. It also displayed the peculiar domed skull typical of mammoths and which is absent on African elephants. Could it have been a late-surviving dwarf mammoth brought all the way from Siberia? Of course, there are alternative interpretations.

It is a large limestone disk 90 centimeters in diameter and 36 centimeters thick. Around its circumference are 33 cups of equal size. A 34th. cup is larger and is located in a sort of ear that extends beyond the normal circumference of the disk. The larger cup is oriented due south. The disk is set in the stone pavement of a small terrace that is slightly elevated above the level of the Central Court. This strange monolith, which dates circa 1,900-1 ,750 BC, has been a puzzle to scholars since its discovery in 1926 by French excavators. C.F . Herberger's thesis is that the disk is a lunisolar clock. The 33 small cups provide a convenient and symmetrical division of the 99 lunations of the 8-year cycle. By moving markers, one could have a fairly accurate lunisolar clock. The 34th. cup, by virtue of its larger size, would announce the need for an intercalcated month. This sort of clock, even though arrived at empirically, represents a remarkable innovation for a period almost 4,000 years ago. (Herberger, Charles F.; "The Mallia Table: Kernos or Clock?"

The postulated wave started out about 375-meters ( -mile) high in Hawaii. By the time is reached Australia, it was about 40 meters high. (SF#85) Worse waves may be on tap. A 4,760 cubic mile chunk of the Big Island (Hawaii) is breaking away at the rate of 4 inches per year.

At 4:48 AM, November 29, 1975, a 37-mile-wide section suddenly dropped 11 feet and slid seaward 26 feet. The result was a magnitude-7 .2 quake and a 48-foot-high tsunami. This was a minor of the slump. If the entire 4,760-cubic-mile block decided to break off, it would probably create a magnitude-9 quake and a tsunami 1,000-feet high.

Greek pyramids! On Greek soil, at Hellenikon and Ligourio west of Athens in the Argolid region, are two limestone pyramids that are stylistically very much like those at Giza near Cairo. The big difference is size; the Greek pyramids are only the size of a large room compared to the Great Pyramid's height (with capstone) of almost 500 feet. 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. The Hellenikon pyramid dates to 2730 B.C .; the Ligourio, to 2260 B.C . This means that the Greek pyramids were built in roughly the same time frame as the Egyptian pyramids. Why would the ancient Greeks want to build miniature pyramids? The classical scholar Pausanias wrote in the Second Century A.D . that the Hellenikon pyramid was a cenotaph for the dead fallen in a fratricidal battle 4,000 years ago.

Kyte et al have now provided additional details on meteoritic debris they first described in 1981. On the floor of the southeast Pacific, about 1400 kilometers west of Cape Horn, about 5 kilometers down, they found high concentrations of iridium in Upper Pliocene sediments about 2.3 million years old. Since the proposed projectile hit in very deep water, no crater was dug out. What did survive is called an "impact melt." This is debris rich in noble metals, such as iridium, and contains particles typical of a low-metal mesosiderite. Some 600 kilometers of the ocean floor received this debris. Kyte and his associates estimate the size of the impacting object at at least 0.5 kilometers in diameter. No biological extinctions are correlated with the 2.3 -million-year date, but there appears to have been a major deterioration of climate at about this time. There was a shift in the marine oxygen isotope records and, more obvious, the creation of the huge loess (sandy) deposits in China. What the impact may have done is to vaporize enough water into the atmosphere to increase the earth's albedo, reflecting sunlight back into space, lowering the average temperature, and thus triggering the Ice Ages.

The largest of these standing stones rises 75 feet above ground level and probably penetrates 12 feet below. Its weight is in the neighborhood of 3,800 tons! This is more than 10 times the weight of Er Grah, the largest standing stone in Brittany and more than twice the size of the massive Trilithon still languishing in its quarry at Baalbek, Lebanon. This latter stone is routinely claimed to be the largest dressed monolith in the world. It isn't !

Whales subconsciously strand and kill themselves in order to maintain their populations at optimum levels! Well, the dozen or so other theories that have been advanced to account for whale strandings haven't been much better. M. Klinowska thinks that she has some clues indicating a better theory. First, all whale strandings (in Britain, at least) occur where magnetic field contours are perpendicular to the shoreline. Second, strandings are also correlated with irregular changes in the magnetic field. You will see the significance of these facts after you hear her theory. "Cetaceans use the total geomagnetic field of the Earth as a map. A timer, also based on this field, allows them to monitor their position and progress on the map. They are not using the directional information of the Earth's field, as we do with our compasses, but small relative differences in the total local field. I arrived at this explanation after a detailed analysis of the records of strandings in Britain, but it has so far been confirmed by two groups working in the U.S .

While the Egyptians piled their weighty blocks neatly into pyramids, the South Americans simply dropped their stones, reed bags and all, onto crude but growing piles. When finished, the largest "rock pile" at Caral contained 7 million cubic feet of rocks and had assumed the shape of a pyramid (or platform mound) four stories high (60 feet) and covering an area 500 by 450 feet.

"Libyan Desert Glass (LDG) represents 1.4 x 109 g of natural glass fragments scattered over about 6500 km2 of the western Desert of Egypt. We made a systematic study (employing INAA, microprobe and mass spectrometry techniques) of several varieties of LDG and locally associated sand and sandstone to provide insight into the nature and formation of these enigmatic glass fragments. These studies indicate that: Although the LDG has restricted major element compositions (97.98 wt% SiO2 ; 1-2 wt % Al2 O3 ) their trace element contents (ppm) (Fe, 490-5200; Co, 0.2 -1 .2 ; Cr, 1.2 -29 and Sc. 0.462.5 ) vary by as much as a factor of 5 to 30. The LDG fragments exhibit a factor of ...

Obviously, evolution "created" these rhythms to further the cause of each moon-tuned organism. Palmer and Goodenough recount the classic example of the lunar synchronism of the palolo worm and add the even-more-amazing tale of P. megalops, another marine worm. Sure enough, the moon-modulated matings of these worms seem to improve reproductive efficiency. Less well known are many other moon-synchronous biological rhythms; viz., the sizes of the pits dug by ant lions to trap ants and the angles flatworms assume in swimming away from light. Many such lunar rhythms apparently have no adaptive value whatsoever. So, why do they exist? Even more disconcerting is the fact that lunar rhythms persist in the lab where the moon is not visible. Are internal clocks responsible here? If so, how do they work and how are they set? These questions are hard to answer if the rhythms have no value to the organism's success. (Palmer, John D., and Goodenough, Judith E.; "Mysterious Monthly Rhythms," Natural History, 87:64, December 1978.) Comment.

The sculpture illustrated was among several found in a cave on the Virginia-Kentucky border. Made life-sized from hard sandstone, it bears curious symbols on its back. Quite obviously, it is the head of an Indian chief, but the symbols might be Libyan, according to Barry Fell. He translates them as: "luminous, radiant, sun-like." Interestingly enough, the ancient leaders of the Natchez Tribe were called "Suns" and wore feathered headdresses like those of the Plains Indians. Further, the Natchez Suns apparently maintained that their ancestors came to North America from North Africa -- thus the Libyan symbols!

... Sunday, June 3, 1984, the 117-foot, threemasted Marques sailed into a fierce squall about 75 miles north of Bermuda. Heavy rain began to pelt the ship, and a furious wind sprang up out of nowhere. Squalls were nothing new to the Marques , one of 39 tall ships participating in a transatlantic race. But as a precaution, Stuart Finlay, the seasoned 42-year-old American captain of the ship, shortened the sails. The Marques was carrying a crew of 28 - half of whom were under 25. At the helm, Philip Sefton, 22, fought the angry waves that now confronted them. "Suddenly a heavy gust of wind pushed the Marques down on its starboard side. At the same instant 'a freakish wave of incredible force and size,' as Sefton later described it, slammed the ship broadside, pushing its masts farther beneath the surging water. A second wave pounded the ship as it went down. The Marques filled with water and sank in less than one minute. Most of the crew were trapped as they slept below deck. Only Sefton and eight shipmates survive." Accounts such as that above are part of sea lore. Waves 50-100 feet high have been frequently reported over the years. Most often, they are encountered in rough seas, but some walls of water have smashed ships in relatively calm waters.

Science Frontiers ONLINE No. 11: Summer 1980 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Orphans Of The Wild West North of San Francisco, all along the Oregon and Washington coasts, the geologically oriented traveller will discover many huge boulders, mostly 10-20 m across, but some 100 m in size. Their constitution varies, but many are coarse-grained basalts that appear to have spent much of their lives at least 30-40 km underground. These boulders are "erratics" in the sense that no one has found surface outcrops that might have given them birth. So, where did they come from? But origin is only part of the problem. The presumable non-glacial erratics occur in a geologically confused area that seems to be upsidedown time-wise according to the few fossils that have been found. One theory is that the erratics were long ago carried to great depths by the conveyor-belt layers that slide eastward and downward under the U.S . Pacific Coast. Later, geological pressures squeezed the rock containing the erratics back to the surface like toothpaste. In the last phase, the matrix rock was eroded away leaving the erratics orphans. (Wood, Robert Muir; "Orphans of the Wild West," New Scientist, 85:466, 1980.) Comment. Note that this complex scenario is dictated by the dogmas of continental drift and the geological time scale.

As these Indians go about their fishing, wood chopping, and honey gathering, tigers are wont to sneak up from behind, spring, and carry off a good-sized meal. But in recent experiments, some 900 volunteers have been wearing human masks on the backs of their heads. This strategem has cut ti-ger attacks drastically. The idea is that tigers, trailing a potential supper, see that human face and figure that the person is alert and watchful. In fact, tigers have been known to track maskwearers for hours without attacking. Pretty clever! How long before the tigers catch on?

... pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Clash Of Hypotheses Millions of Mima Mounds dot various terrains west of the Mississippi, from British Columbia south to northern Sonora, Mexico. They are also found in Africa and South America. Mima Mounds are formed of soil and small stones. They are often 2 meters high, with diameters of 20 meters. Mound densities can reach 25-50 per hectare. Mima Mounds, prai-rie mounds, pimple mounds, or whatever they are called locally, are widely thought to be the work of pocket gophers, although this hypothesis is still contested, as we shall see below. No one denies that pocket gophers are often associated with the mounds. In fact, a recent scientific paper describes the relationship between the sizes and shapes of the mounds and the numbers of resident gophers. The authors of this paper, G.W . Cox and J. Hunt, state confidently that: The seismic waves intersect, an interference pattern forms. Loose surface material collects at points of minimum surface disturbance (open circles). "Investigations of Mima mounds in western North America support the hypothesis that mounds are formed by the gradual translocation of soil by pocket gophers..." (Cox, George W., and Hunt, Jodee; "Form of Mima Mounds in Relation to Occupancy by Pocket Gophers," Journal of Mammalogy, 71:90, 1990.) In another paper, appearing at almost the same time, A.W .

"At 1200 GMT large patches of milkygrey bioluminescence were observed; the patches appeared to form circular patterns resembling cartwheels, some of the configurations, however, did not have the central hub, see sketch. The patches pulsated at regular intervals (3 or 4 times per second). They moved in an anticlockwise direction until about 3 points abaft the beam where the direction of movement was reversed. On the beam they appeared to be at eye level, at all other times they were just above the surface of the water. The average size of the 'wheels' was 35 metres." (Penman, B.; "Bioluminescence," Marine Observer, 50:114, 1980.) Comment. A similar case of spinning boomerangs was reported in Lightning, Auroras, Nocturnal Lights, where the display was stimulated by switching the ship's radar on and off.
