That's quantum weirdness all right, but this weirdness can also produce effects we can see and hear. All you have to do is cool helium down to almost absolute zero. It will liquify but, unlike most other gases, it will not freeze. You are surprised at this, of course. Now, if you spin a bowl of this liquid helium around, you will be astounded. 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. A drop climbs up the inside of the cup, then runs down the outside. When it falls, another begins climbing, and the magic continues until the cup is dry."

Because chromosomes are composed of genes and their DNA -- the information carriers of inheritance -- it reasonable to suppose that they are the "dance-masters." This expectation is enhanced if one holds that the genes are "selfish;" that is, they have their own evolutionary agendas, and all life forms exist only to execute their "will." But cell division would not occur at all without the action of the cell's bipolar spindle. This spindle is composed of microtubules -- rods of the protein "tubulin." Somehow , when cells are about to divide, they synthesize these microtubules, which then seem to organize themselves into orderly arrays (the bipolar spindles). Then, the microtubules sort out and separate the two sets of chromosomes required for the two new cells. So, far, our description conforms to what biologists have known and accepted for decades; but there is something more mysterious going on. In 1996, researchers discovered that they can actually substitute DNAcovered beads for the chromosomes, and the microtubules will still go through the motions of sorting and separating the chromosome-less strands. Actually, the microtubules will perform their act even without the DNA-covered beads. In a sense, the bipolar spindle is a puppetmaster, and the ...

Podkletnov discovered this amazing effect when researching superconducting materials, However, he used only a single ring, which resulted in a 2% weight reduction.

R.G . Everit responds that this is not really mysterious. The better chess-playing computers are actually designed to behave unpredictably when confronted by several moves of roughly equal promise. This feature makes it more interesting for human players. Everit also sets us straight in the matter of computer determinacy. "However, contrary to your basic assumption, most computers (even a home PC) can be forced to behave truly unpredictably. This cannot be done using the random-number generators supplied with the software, as these depend upon some mathematical formula and so are determined in advance, even if they appear to show no pattern. But if the machine has an internal clock readable by the programmer, he can determine the machine's choice depending upon the time required for some complex calculation, which will vary according to such factors as minute voltage variations and the aging of the machine's components. For example, the CDC 3600, on which I learned to program in 1975, had an accessible microsecond clock, and my program to calculate the first five perfect numbers* required about 15 minutes of run time; the last few digits of the exact number of microseconds required to run this program each time varied quite unpredictably.

In some situations, though, the increase in disorder (entropy) in one part of the universe can create order elsewhere. For example, if you add tiny plastic spheres of two sizes to salty water, you will not get a uniform mixture. Instead the larger spheres will pack together into tightly ordered crystaline shapes (representing more order) while the smaller spheres become more disordered. It is like watching cream unstir itself from coffee. It smacks of magic, but it is all within the laws of thermodynamics. This strange "force" exerted by entropy may explain some puzzling biological phenomena, such as the expulsion of nuclei from mammalian red blood cells before they enter the bloodstream as sacks of hemoglobin. The idea being that the increasing entropy of the proliferating hemoglobin molecules (analogous to the smaller spheres) is maximized when the nuclei (large spheres) are squeezed out of the cells altogether. (Kestenbaum, David; "Gentle Force of Entropy Bridges Disciplines," Science, 279:1849, 1998.) Comments.

This will have to come later. These "circles of contention" are engraved on tall boulders (about 2 meters high on average) arranged in arcs hundreds of meters long at a site the aborigines call Jinmium. Jinmium is located near the western boundary of Australia's Northern Territory. The circles are obviously the work of humans. There are thousands of these etchings all told. Dimensions: 2-3 centimeters across and about half as deep. No one doubts that the Jinmium site is ancient. Judging from the sediments that cover the lowest circles, these engravings are about 60,000 years old. If this date survives scrutiny, the Jinmium carvings will be the oldest human art on the planet -- twice as old as anything found in Europe. No wonder the circles have created a stir.

It is generally known that you can separate fresh eggs from hard-boiled eggs by spinning them like a top. If they are hard-boiled they will spin on one of the ends. The fluid contents of fresh eggs, however, will slosh around and prevent top action. O.K .! this is not very curious, 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.

Newcomb had noticed that books of logarithms in the libraries were always much dirtier at the beginning. Hmmm! Were his fellow scientists looking up the logarithms of numbers beginning with 1 more frequently than 2, 3, etc.? It certainly seemed like it. He formalized his suspicions in a conjecture: p = log10 (1+ 1/d ) Where p = the probability that the first significant digit is d. This (unproven) equation states that about 30% of the numbers in a table or group will begin with 1. Only about 4.6 % will begin with 9. This result certainly clashes with our expectation that the nine digits should occur with equal probability. Fifty-seven years later, F. Benford, a GE physicist, unaware of Newcomb's paper, observed the same dirty early pages in the logarithm tables. He came up with exactly the same conjecture. Benford didn't stop there. He spent several years collecting diverse data sets -- 20,229 sets, to be exact. He included baseball statistics, atomic weights, river areas, the numbers appearing in Reader's Digest articles, etc. He concluded that his (and Newcomb's ) conjecture fit his data very well.

... How has planetary self-regulation (Gaia) been established and maintained by evolution and natural selection which operate on the level of individuals? In other words, evolution tells us that organisms should evolve so as to leave the most progeny not so as to regulate the atmosphere. Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it is a tangled bank! All of the feedback loops imply that the evolution of life forms is constrained (or dictated) by the need to keep the planet livable and not to simply leave the most progeny, but rather the progeny that will best serve Gaia! (Lenton, Timothy M.; "Gaia and Natural Selection," Nature, 394:439, 1998.) Comments. The obvious implication is that all life forms, including humans, are parts of a planet-sized super-superorganism.

Furthermore, human operators can specify a hardware goal to the chip and let it evolve on its own, something it can do in microseconds rather than millions of years. This is not a frivilous subject. D. Fogel, chief scientist at Natural Selection, Inc., in La Jolla, California, asserts: "Eventually, we will need to know how to design hardware when we have no idea how to do it."

(SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm ...

"This article proposes an integrated psychodynamic perspective to account in part for a variety of similarities between near-death experiences and UFO abductions. The psychodynamic psychology of these experiences implies that their "realness" is mainly a function of that psychology, rather than primarily of an objectifiable external reality. Clinical and research examples highlight the theoretical and practical usefulness of this model." (Twemlow, Stuart W.; "Misidentified Flying Objects?

The prevailing dogma has long been that the Indians who built Cahokia worked only with earth, never with stone. Indeed, suitable stone is scarce in the area. On January 24, 1998, while drilling to construct a water drainage system at Monk's Mound, workers hit stone -- at least 32 feet of it -- perhaps a region of cobbles or slabs of rock. This region of stone, of undetermined geometry, is located 40 feet below one of the terrace surfaces, but still well above the base of the mound. The stones could well be an artificial structure of some sort. The discovery challenges the current thinking about the culture that built Cahokia. Only further research will reveal the extent and configuration of the stony region and where the stones may have come from.

(SF#84/279) We now have more precise data. Wave-height measurements at the Seven Stone Light Vessel, anchored in the northeastern Atlantic, show that wave heights have increased 2.4 centimeters/year during the period 1960-1985. This is not a trivial amount. At this rate, waves a century from now would be 2.4 meters (about 8 feet) higher. Many existing coastal structures will be smashed to bits. All this is over and above any effects from rising sea levels. The records from the Seven Stone Light Vessel are corroborated by an analysis of more then 20,000 wave charts of the North Atlantic drawn between 1960 and 1988. It therefore seems clear that something unusual is going on in the North Atlantic. One would suspect increased winds, but velocities measured at Seven Stone have remained constant while wave heights rose. It is concluded that the bigger waves are not generated by local winds; rather, they are swells that have been created thousands of miles away. The cause of these larger swells now affecting the entire North Atlantic is not known. The authors of this paper are forced to conclude with: "It should be noted that so far it has not been possible to attribute the observed change to either an anthropogenic cause or to natural climate variability on decadal time scales."

Half of all dreams allude to events of the preceding day; 89% allude to events of the last 120 days. The older the event, the lower the odds that it will reappear during the night.

He notes that General Relativity predicts that a particle (or person) in free fall cannot distinguish this condition (weightlessness) from the situation in a hollow shell of matter, where the gravitational field is cancelled out. 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.

... of the men in the crew smiled at me and beckoned me to come closer to the gun. When I drew near he pointed to the exposed end of the left trunnion. Mounted there was the control potentiometer of my level recorder. There was no mistaking it. It was the identical item." Bell Lab engineers quickly saw how Parkinson's potentiometer could be applied to antiaircraft gun control. The M9 gun director was the practical result of Parkinson's dream. In one week in August of 1944, the M9's were credited with destroying 89 of 91 V-1 buzz bombs launched from the Antwerp area toward England.

... of New Scientist. "My wife and I saw a puzzling sight in October 1994, in the Mekong River near Nongkhai, Thailand, during a full moon, in the evening. Lights appeared under the water for a few hundred metres along the Mekong River. They rose from the bottom of the river and floated to the surface, then shot like missiles into the sky and out of sight. They were the size of beach balls, and many flew out of the water every few minutes, surfacing about 10 metres apart. I am told that this happens every year at the same time. Locals say it is caused by a serpent releasing her eggs. Does anyone know of this phenomenon?" A. Pentecost answered. He noted first the similarity of the Mekong phenomenon to the will-o '- the-wisp or ignis fatuus. The usual explanation of ignis fatuus blames the spontaneous combustion of marsh gas. However, the Mekong lights are initially seen under the water where there would not be enough oxygen to support combustion. Pentecost suggested instead phosphorescent bacteria or the "cold flame" of phosphorus vapor which might form through diphosphane decomposition. (Pentecost, Allan, et al; "Mekong Mystery," New Scientist, p. 96, September 6, 1997.) References. The Mekong phenomenon may be allied with the many examples of luminous aerial bubbles.

Science Frontiers ONLINE No. 110: Mar-Apr 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Martian Life: Act Ii The final issue of New Scientist for 1996 carried an article entitled "Death Knell for Martian Life." Was all that media hype for naught? What will NASA do now? Wait! Another putative Martian rock may save the day. Picked up in Antarctica in 1974, meteorite EETA 79001 weighs 7.9 kilograms and is superficially unimpressive. Inside, though, researchers I.P . Wright and C.T . Pillinger found a surprising quantity of organic compounds -- actually 1.5 parts per thousand by mass. This fraction is so large that terrestrial contamination seems remote. Furthermore, the organic component contains 4% more carbon-12 (relative to carbon-13) than the adjacent carbonate minerals. This is strong evidence that the organics had a biological origin. Similar tests on the media-hyped Martian meteorite ALH 84001 yielded the same carbon ratios. Pillinger remarked: "These results offer the strongest support yet for the hypothesis that life once existed on the planet." So far so good, but EETA 79001 conveys two additional facts -- both very tantalizing: (1 ) This meteorite was blasted off the Martian surface only about 500,000 years ago; and (2 ) It probably came from a different hemisphere than ALH 84001. From all this, a somewhat shaky conclusion: Life on Mars existed not only recently (and perhaps is still present) but was ( ...

... taken to be manmade cut, stacked blocks were no more than a type of natural rock formation." P. Andrews, the author of this article likened the regular jointing of the "wall" to neatly hexagonal prisms seen in many basalt flows. He supplied two photographs of the "wall." One was like the photo in SF#107 and showed regular joints; the second, from the same outcrop, displayed angled fractures and joints that certainly do not look like the work of humans. (Andrews, Philip; "New Zealand: Recent Ash, Ancient Wall," Geology Today , p. 136, July-August 1996. Cr. R.E . Molnar) Comments. If we receive counter-arguments from proponents of the wall's artificiality, we will add them to this dossier. A similar situation occurs with the more-famous Bimini "walls" or "roads." We have personally seen beach-rock deposits so regularly jointed that they seem man-made. From Science Frontiers #110, MAR-APR 1997 . 1997-2000 William R. Corliss ...

... the very early universe was already partitioned by colossal walls of galaxies hundreds of millions of light years long. That walls of galaxies exist is not a new idea, but finding that they existed shortly after the Big Bang is highly disconcerting to most astronomers. How did these walls form so early? Why hasn't the force of gravity modified the basic structure of the cosmos over the billions of years that followed the Big Bang? The astronomical quandry is this: If the very early universe looks pretty much the same as today's universe, the implication is that mass, the source of gravitational sculpting, is scarce. But this is at odds with the cosmic expansion rate which implies a much higher density of matter. (Appenzeller, Tim; "Ancient Galaxy Walls Go up; Will Theories Tumble Down?" Science, 276:36, 1997.) Comment. The existence of galaxy walls, like so many astronomical constructs, depends upon the assumption that the red shifts of galaxies are proportional to their recessional velocities and, additionally, their distances and ages. So much rides on this one assumption. The same situation prevails in biology, where everything is founded on the assumption that random mutations and natural selection can together generate any degree of complexity, sophistication, and innovation seen in nature. The history of science tells us that many paradigms have fallen because they depended upon faulty assumptions. From Science Frontiers #116, MAR-APR 1998 . 1998-2000 William R. Corliss ...
