... : wind or water deposits?In response to the item in SF#92 about possible massive flooding in Siberia, E. Hansen sent the accompanying mosaic of Landsat photographs of northwestern Nebraska. On this, the famous Nebraska sandhills appear like giant ripples. The width of the mosaic is about 340 kilometers, so you can appreciate the scale of the hills themselves. The crest-to-crest distances seem to be 2-3 kilometers. Roughly 35,000 square kilometers are covered with a sheet of sand that averages 8 meters thick. Mainstream geologists write these sandhills off as eolian (wind-carried) deposits laid down during the late Pleistocene. Hansen, however, along with geological iconoclast A. Kelly, demur. The Nebraska sanhills, they aver, were actually deposited by a wall of water sweeping down across the continent from the north -- very likely the consequence of an impact of a large asteroid. For more on Kelly's rejection of the eolian theory and many additional examples of deposits by huge tsunamis or marine incursions, see his book Impact Geology and/or category ETM7 in our catalog volume: Carolina Bays, Mima Mounds, etc. (To order the latter book, visit here .)

The 2.5 million multiton limestone blocks in the Great Pyramid are more than ample proof of their ability to work this soft stone. But how about the polished black granite walls of the King's Chamber in the Great Pyramid and the hollowed-out sarcophagus of obdurate chocolate-colored granite in the same room? These granites are much harder than limestone and even harder than the copper saws and drills that the Egyptian stoneworkers had at their disposal. So, how did they work their granite? [No lasers allowed!] The King's Chamber in the Great Pyramid is encased with multiton blocks of hard-to-work granite. For some reason the five granite slabs in the ceiling were finished on only their bottom sides. (From: Ancient Structures) As a matter of fact, there is little mystery here despite what you read in the popular magazines. The Egyptian workers simply dribbled quartz sand beneath the copper saws and drills. This abrasive is harder than the mica and feldspar components of granite but not the quartz. Nevertheless, granite will yield slowly to the abrasive, as do the copper tools themselves. In 1999, D.A . Stocks tested the efficacy of copper saws and drills on the granite in the Aswan quarries 500 miles up the Nile. The copper saw in his test was 1. ...

... R.; Pyramid Odyssey , 1978 A German roboticist, R. Gantenbrink, was hired to clean out the debris clogging the 8-inch-square "ventilation" shafts in the King's Chamber of the Great Pyramid at Giza. Remotely controlling a robot resembling a miniature tank, Gantenbrink subsequently explored the cleared shafts. Finding nothing worth noting there, he requested permission to send the robot crawling up a similar shaft in the Queen's Chamber below. Early archeologists had already plumbed this shaft with long pipes and had concluded that it ended after about 9 feet. Gantenbrink's robot, using its camera eye, found that this shaft did not end where expected but instead veered upward at a 45 angle. Climbing the incline, the robot found that the texture of the limestone walls changed from the rough-hewn, locally quarried limestone to the highly polished tura limestone often found in the entryways of tomb chambers. "At the end of the polished section was what appears to be a door, made of the same tura limestone and with tongue-and-groove fittings on the side that suggest it can be raised and lowered. It has two corroded copper fittings in the center; a piece of one fitting had broken off and was found lying in front of the stone. A small gap exists at the bottom of the stone, but the camera could not peer through it." But what could lie beyond this tiny door deep in a shaft too small for humans? Is there a hidden chamber? Might it contain the body of Khufu, builder of ...

... called "nuraghi." (Singular form is "nuraghe.") Over 7,000 of these remarkable dry-stone edifices exist -- a concentration of monumental stone architecture unparalleled in Europe. "' Nuraghe' derives from the prehistoric Sardinian root 'nur' which means both 'hollow' and 'heap.' But the nuraghi are neither hollow nor are they haphazard heaps of stone. The nuraghe interior often presents a complex plan of chambers, winding staircases, dead-end corridors, concealed rooms with trap doors, and a variety of niches and compartments. Standing up to three stories high with magnificently corbelled domes one on top of the other, some structures have as many as 18 subsidiary towers attached to the main keep. Large complexes were sometimes completely enclosed by enormous stone walls punctuated with still more towers." Ocer 3,000 years old, the nuraghi have withstood the depredations of weather and later humans by virtue of their excellent design and construction. As with many other such ancient structures, one is impressed with the size of the stones used. How were they moved? How were the stones -- usually hard basalt -- cut and dressed by artesans with no metal tools harder than copper or bronze? And what was the purpose of the nuraghi? A quick answer to the last question is that they were fortresses, but they might also have been dwellings or storehouses.

... Plants are not color blind!" Scientists have long known from laboratory experiments that various colors of light can affect stem size, root structure and other aspects of plant growth. But they have remained largely in the dark about the potential practical benefits of the phenomenon. "Using colored mulch to bathe plants in reflected light of certain hues, the South Carolina group (Clemson University) has begun to explore what colors plants prefer in agricultural growing conditions. Last year, for example, the group found that tomatoes grown with red mulch -- made with plastic sheets painted red -- had 20% higher yields than those with black mulch. Preliminary results this year show that potatoes and bell peppers grow best with white mulch...." (Anonymous; "Plants' Colors," Wall Street Journal, September 16, 1987. Cr. J. Covey.) Comment.

A photo taken by divers does reveal a remarkably regular, stepped surface, but nature can be very methodical on occasion. Adding to the artificiality of the "structure" is the claim that a "road" encloses it. (Barot, Trushar; "Divers Find World's Oldest Building," London Times, April 26, 1998. Cr. A.C .A . Silk & D. Phelps) Comments. If this submerged "structure" is really man-made, it would make Hapgood's Maps of the Ancient Sea Kings more plausible. Other nicely regular "structures," very likely natural, are: the Giant's Causeway, the Bimini Road, the Kaimanawa Wall, the Face on Mars, etc. Called a "monument" by some zealous explorers, this Okinawan undersea structure does exhibit many suspicious regularities.

... so we'll place a hard-boiled egg in a flat pan containing a thin layer of water and give it a spin. Not only does the egg spin on end but a layer of water creeps up the side of the egg. When the water is about half way up the side of the egg it breaks up into droplets and sprays out horizontally like a rotating lawn sprinkler. No mysterious forces are involved, nor are there spooky quantum mechanics effects. The major forces operating are gravity, centrifugal force, and adhesion between the egg surface and the water. As the film of water creeps up the egg, the centrifugal force increases and overcomes the force of adhesion. Then, water droplets spray outward. (Gutierrez, Gustavo, et al; "Fluid Flow up the Wall of a Spinning Egg," American Journal of Physics, 66:442, 1998.) Creating fluid corners in kitchen sinks. When a smooth column of water from your kitchen faucet hits the sink, it flows out radially. At a calculable radius, its height suddenly rises. This smooth, circular ridge is called a "hydraulic jump." Here, some of the kinetic energy of the falling water is converted into the potential energy of the deeper layer of water. Nothing particularly mysterious here. But, if a liquid more viscous than water is used, the circular ridge is transformed into a neat polygon with surprisingly sharp corners. Different flow rates create different polygons. Polygons with as many as 14 corners have been observed. Interestingly, identical flow rates can result in different ...

... incredible velocity. "I lay back on my left elbow, to afford the baby better protection, and looked up. It is possible that in that upward glance my stricken eyes beheld something few have ever seen before and lived to tell about it. I was looking far up the interior of a great tornado funnel! It extended upward for over a thousand feet, and was swaying gently, and bending slowly toward the southeast. Down at the bottom, judging from the circle in front of me, the funnel was about 150 yards across. Higher up it was larger, and seemed to be partly filled with a bright cloud, which shimmered like a fluorescent light. This brilliant cloud was in the middle of the funnel, not touching the sides, as I recall having seen the walls extending on up outside the cloud. "Up there, too, where I could observe both the front and back of the funnel, the terrific whirling could be plainly seen. As the upper portion of the huge pipe swayed over, another phenomenon took place. It looked as if the whole column were composed of rings or layers, and when a higher ring moved on toward the southeast, the ring immediately below slipped over to get back under it. This rippling motion continued on down toward the lower tip." Hall also reported a peculiar bluish light and blue streamers that appeared to consist of vapor.

... and even the behavior of their host. The object is usually to encourage a specific predator to eat the host so the parasite can continue its life cycle. A classic example is the lan-cet fluke which infests ants and then sheep. The problem is that sheep don't normally eat ants, giving the flukes a chance to switch vehicles. So, the innovative flukes somehow force the ants to crawl to the tops of plants and lock themselves there with their jaws. The next hungry sheep that comes along has his meal seasoned with ants. The bulk of the present article deals with thorny-headed worms, which are not as endearing as the lancet flukes. These parasites are merely bags of reproductive organs attached to a thorny probiscus, by which they attach themselves to the intestinal walls of vertebrates. Living in a sea of processed nutrients, the worms don't even have a digestive tract. Part of the life cycle of this parasite is spent in arthropods (insects, crustaceans). As with the lancet fluke, the thorny-headed worm's big challenge is getting the arthropod eaten by a vertebrate. In most instances, it alters the behavior of the arthropod in a way that makes it more conspicuous to the predators. For example, infested pill bugs do not hide from birds, as they normally do, and are snapped up. Infested crustaceans move towards the light where ducks consume them. No one knows how a parasite floating in the body cavity of its host can control the host's behavior. (Moore, Janice; "Parasites ...

Many keep birds, insects, fish, etc. as pets. When scientists at the Osaka City University asked for reports of unusual animal behavior around the time of the great January 17 quake, over 1,200 people in the Kobe-Osaka area came forth with anecdotes. Some typical pre-quake observations were: Doves flying into walls. Caged birds (Chinese hawk-cuckoos) flying against the sides of their cages. Fish rising to the surface in great numbers. At the port of Shioya, "millions" of gizzard shad turned the surface of the water into silver. Captive stag beetles and turtles emerging from hibernation. And strangest of all, silkworms and fish in ponds orienting themselves in the same directions.

... code, continental drift, nuclear fission, and so on and so on. More sober scientists rejected such extravagant claims. They pointed out that independent confirmation of the fluctuations was yet to come and that, after all, the fluctuations were very small (only some 30 millionths of a K). And which of the many variations of Big Bang was going to be enthroned? Even Nature advised extreme caution, quoting H. Bondi in this regard: ". .. the data in cosmology are so likely to be wrong that I propose to ignore them." (Anonymous; "Big Bang Brouhaha," Nature, 356:731, 1992.) Comment. It is ironical that before astronomers found large-scale inhomogeneities in the cosmos (galactic clusters and superclusters, the Great Wall, etc.), the Big Bangers claimed that the very smoothness of the microwave background proved the reality of the Big Bang. The Big Bang, it seems, is one of those "politically correct" paradigms, which one criticizes at his peril. (Beichman, Arnold; "The Big Bang Censorship," Insight , p. 22, April 13, 1992. Cr. B.

We obviously have a lot to learn about this new realm between single atoms/molecules and bulk materials. Quasicrystals . Quasicrystals, once considered physically impossible, have been found easy to grow -- once one's mindset is corrected. At Bell Labs, for example, quasicrystals of an aluminum-cobaltcopper alloy reveal atoms packed together in pentagonal arrays -- the very geometry that crystallographers assured us could not exist. As one of the Bell researchers remarked, "Most of the ap plications are unimagined." This goes for the basic properties of quasicrystals, too. (Keller, John J.; "Bell Labs Confirms That New Form of Matter Exists," Wall Street Journal, February 8, 1990. Cr. J. Covey.) Nitrogen molecules that shouldn't exist .

... for much exaggeration. In his present contribution, Stevenson reports three cases in Sri Lanka where the recollections of the supposedly reincarnated children have been written down in detail and the family of the deceased has not been located. Here is one of his cases: "The Case of Iranga . The child was born in a village of Sri Lanka near but not on the west coast, in 1981. When she was about 3 years old she spoke about a previous life at a place called Elpitiya. Among other details, Iranga mentioned that her father sold bananas, there had been two wells at her house, one well had been destroyed by rain, her mother came from a place called Matugama, she was a middle sister of her family, and the house where the family lived had red walls and a kitchen with a thatched roof. Her statements led to the identification of a family in Elpitiya, one of whose middle daughters had died, probably of a brain tumor, in 1950. Among 43 statements that Iranga made about the previous life, 38 were correct for this family, the other 5 were wrong, unverifiable, or doubtful. Iranga's village was 15 kilometers from Ilpitiya. Each family had visited the other's community, but they had had no acquantance with each other (or knowledge of each other) before the case developed." Stevenson's conclusion was that the three children had information about deceased persons that could only have been obtained paranormally.

... ruins, there is little to help pin down these miners. Mainstream archeologists attribute all these immense labors to a North American "Copper Culture" -- certainly not to copper-hungry visitors from foreign shores. Admittedly, many copper artifacts have been dug up from North American mounds, but only a tiny fraction of the metal the Michigan mines must have yielded. Curiously, North American Indian mounds have contained copper sheets made in the shape of an animal hide. Called "reels," their function, if any, is unknown. The reels do, however, resemble oddly shaped copper ingots common in European Bronze Age com merce. Their peculiar shape earned these ingots the name "oxhydes." They have been found in Bronze Age shipwrecks, and are even said to be portrayed in wall paintings in Egyptian tombs. The standardized hide-like shape, with its four convenient handles, was useful in carrying and stacking the heavy ingots. Could the reels from the North American mounds have been copied from the oxhydes? It is tempting to speculate (as we are wont to do) that the Copper Culture miners were actually Europeans, or perhaps Native Americans employed or enslaved by Europeans -- an omen of future, more devastating invasions!

Deep in the Altai Mountains of southern Siberia. About this date, a wall of water 1,500 feet high surged down the Chuja River valley at 90 miles per hour. How does one deduce such a hydrological cataclysm? A. Rudoy, a geologist at Tomsky State Pedagogical Institute, points to giant gravel bars along the Chuja River valley. These are not the inch-sized ripples we seen on the floors of today's rivers; these are giants measuring tens of yards from crest to crest. Only a catastrophic flood could have piled up these ridges of debris. Rudoy postulates that, during the Ice Ages, a huge ice dam upstream held back a lake 3,000 feet deep, containing 200 cubic miles of water. When the ice dam suddenly ruptured, all life and land downstream was devastated. (Folger, Tim; "The Biggest Flood," Discover, 15:36, January 1994.) Comment.

The liquid remains absolutely stationary in its spinning container -- no centrifugal effects, no friction with the contained wall, nada!. However, the strangest part comes when you: "Draw a cupful out of the bowl, suspend it a few centimeters above the remaining liquid, then stand back and rub your eyes -- the fluid in the cup will cheat common sense by pouring itself, drop by drop, back into the bowl.
