It is, of course, this low average temperature of the spiritual world that accounts for the chill felt when a spiritual entity (ghost) enters a room and is coupled to the material world. Continuing on this tack, Jones now plans to measure whether holy relics and other material objects with high spiritual value cool faster than non-spiritual objects. He also hopes to work with biological materials, specifically the human brain, which is the seat of consciousness and spiritual thought. Human brains, particularly those of holy men, should be tightly coupled to the cold spiritual world. These human brains should cool much faster than, say, a sirloin steak. Speculating even further, Jones proposes to test semiconductors to determine whether they cool faster than ordinary minerals. If they do and since semiconductors form the brains of computers, it is reasonable to suppose that computers could eventually become conscious entities and perhaps even acquire a spiritual dimension!

(b ) There is a small tendency for the days on onset of cases of poltergeists and hauntings to be days of higher-than-usual geomagnetic activity. What underlies these observed relationships remains to be determined." Gauld noted in his letter of transmittal that the conclusions of Wilkinson and himself were at variance with the item in SF#95.

Shaw contends that cosmic projectiles -- asteroids and comets -- have controlled almost all features of the earth's evolution. For example: Impacts have determined the positions of the continents. They have controlled the geomagnetic field. They have created volcanoes and massive basalt flows. They have caused mass extinctions. Of course, for two centuries, other catastrophists have proposed similar dire consequences of giant impacts. But Shaw does introduce three ideas that are worth recording here. 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.

We have seen no formal studies of nominative determinism, but we have just discovered a closely allied phenomenon that has been scientifically investigated. We call it "monogrammic determinism.' An individual's monogram does not seem to be associated with his or her occupation but rather with longevity. People with monograms such as ACE, WOW, or GOD tend to live longer than those with monograms like PIG, RAT, DUD, or ILL.

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.

Particles can be strangely connected over at least ten kilometres, according to results from physicists in Geneva. Using pairs of "entangled" photons, Nicolas Gisin and his colleagues from the University of Geneva have shown that the measurement of one particle will instantaneously determine the state of the other." (Ref. 2) This particular spooky aspect of quantum mechanics was demonstrated 15 years ago over a distance of just a few meters. Many physicists had expected (probably "hoped") that this "mysterious link" between separated particles would weaken with distance.

These punctures do not seem to be ornamental, like those on a sailor's biceps, nor are they on parts of the body usually displayed. What is most interesting are their locations; some groups are placed at traditional Chinese acupuncture points. Bolstering this suspicion is the determination from computer tomography (noninvasive imaging) that the Iceman suffered from arthrosis of the lumbar spine. The Iceman's body is punctured at the points usually used by acupuncturists to treat this condition!

Other terrestrial animals are also asymmetrical in various ways. But on the molecular level, terrestrial biochemistry is all left-handed. As far as scientists can determine, only left-handed amino acids are incorporated into proteins. In nonlife (if such a state really exists), amino-acid molecules are right- and lefthanded in equal numbers -- as least this has been the theory up until now. Amino acids are found in substances we assume are non-life or of abiotic origin. In fact, amino acids are present in meteorites, often in substantial amounts. They are profuse in Australia's Murchison meteorite, a carbonaceous chondrite. However, analysis of the Murchison's amino acids indicates that there are slightly more (7 -9 %) left-handed than right-handed amino acids present. This extraterrestrial handedness is of great import to both cosmologists and biologists, because the carbonaceous chondrites are thought to have formed 4.5 billion years ago -- long before life on earth originated. Furthermore, some of the Murchison's amino acids have never been found in terrestrial life, and they are also slightly left-handed.

Rayner's new book Degrees of Freedom: Living in Dynamic Boundaries , T. Wakeford writes: "So, like the World Wide Web, a fungal network is decentralized. There is no central region capable of exerting control over the rest of the network. Rayner's own work suggests that the growth patterns of fungal filaments are forged as much by the environment that they encounter as by their genes. He believes that epigenetics, the process whereby opportunities in an organism's surroundings dictate which genes are expressed, is the norm in microorganisms. Genetic determinism is thus turned on its head." (Wakeford, Tom; "We Are the Fungus," New Scientist, p. 49, May 10, 1997.) Comment. Looking at the above situation from an information viewpoint, as one must these days, it seems that the environment can somehow "interpret" genes as the situation demands. In other words, genes are not "single-message" information carriers, but can be "read" in different ways according to the environment encountered by their "carriers"; that is, the organisms that bear them. Is this how "adaptive evolution" works? If it is, the genome must contain a multitude of "contingency plans" because the environment by itself cannot add a new suite of capabilities to the ...

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.) ...

The age of formation for these tektites, as determined by both fissiontrack and potassium-argon dating lies between 700,000 and 860,000 years. Geological evidence, however, suggests that the tektites fell only 7,000 to 20,000 years ago -- a substantial discrepancy. Surely, say some, these old tektites were washed out of some equally old deposits and transported to the young strata where they now reside. Not so, say Australian geologists, because most of these tektites are found in areas devoid of outcroppings 700,000 years old. Furthermore, the rather fragile tektites show little signs of wear, as they should if transported by flood waters for long distances. These and other geological facts militate against the 700,000-year date. Geologists have questioned the two dating techniques, while geophysicists think the geological evidence is shaky. (Chalmers, R.O ., et al; "Australian Microtektites and the Stratigraphic Age of the Australites," Geological Society of America, Bulletin, 90:508, 1979.) Comment.

We usually do not study comets carefully until they are very close to the sun, so we don't know if this blinking behavior is typical or not.

The two assumptions implicit in this classification procedure, which is supposed to mirror actual historical evolution, are: Malarial parasites evolved in parallel with their hosts; and Morphology is a measure of evolutionary relatedness. With modern biochemical techniques it is possible to test these assumptions by comparing the DNA structures of the different malarial parasites. P. falcipa rum, the parasite transmitting the most deadly human malaria, turns out to be more closely related to rodent and avian malaria than the other primate malarias. Therefore, assumption #1 above is in correct in this view. Assumption #2 is also wrong because some species of malaria parasites which are very similar morphologically are quite different DNAwise.
