Science Frontiers ONLINE No. 36: Nov-Dec 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Magnetic Jerk Problem We reported above that the earth's magnetic field "jerked" in 1969; that is, it suddenly accelerated its westward drift. The earth's core, which through dynamo action reputedly generates the magnetic field we detect at the surface, apparently does not keep pace with the outer crust. It is this sluggishness that produces the observed westward drift of the magnetic field of about 1 meter per hour. While most geophysicists acknowledge that something significant happened to the core in 1969, the geographical extent of the "jerk" is unclear. The acceleration of the field was clearcut in Europe but obscure or undetectable over much of North America. If the jerk was geographically limited, the core perturbation probably was, too. The earth's core may, in fact, eddy and swirl like the planet's atmosphere. Going over past records, geophysicists think they have spotted another jerk in 1912; only that time the field decelerated.

The change was almost synchronous over the whole of the Earth's surface, took place in less than two years, and is now known to have consisted of a 'jerk': a step change in secular acceleration of the magnetic field that has its origin inside the Earth." (Whaler, K.A .; "Geomagnetic Impulses and Deep Mantle Conductivity," Nature, 306:117, 1983.) Comment. No one really knows just how a "jerk" in the magnetic field is initiated; in fact, the origin of the geomagnetic field as a whole is not well-understood.

... engendered many a sensational article in the popular press. Atlanteans and even extraterrestrials have been credited with the building of the "road" and other constructions reported around the Caribbean island. The fact is that the "road" does exist, but the weight of opinion among those who have investigated it is that it is a natural formation of beach rock fractured in a disturbingly regular manner. But this assessment does not mean that all anomalies in the shallows around Bimini have been exorcised. D.G . Richards, in a splendid article in the Journal of Scientific Exploration gives us a blow-by-blow account of the investigations (both amateur and professional) of Bimini waters. It is a curious panorama of wild claims by adherents of the Cayce-inspired Atlantis searchers and the knee-jerk academic scoffers - both of which go overboard! Be this as it may, our purpose here is the recording of some of the features near Bimini that Richards thinks are still anomalous. Three of these are located at A, B, and D in the accompanying drawing, which is based on an aerial photo taken at 6,000 feet. A is a 90 bend in the renowned "road." This bend is decidedly anomalous for a beachrock formation. B consists of a parallel row of stones. D is made up of regularly spaced piles of stones and extends over 1 miles, cutting diagonally across ancient beach lines. Richards also employed a satellite image of the area to locate other "regular" features, such as a triangle, a pentagon, and a sharp, ...

... duration of several seconds and an explosion (thunder and ground shock) took place. (According to some reports. at first a 'glowing object' flew down to the ground.) Probably light phenomena were present at some other places. "The 1991 Sasovo explosion was accompanied by a number of intri-guing phenomena, sometimes resembling (ball) lightning and even tornado damage. There was some unusual and selective damage in the town and even in the village 20 km from the epicenter. Azimuth distribution of hurled frozen soil from the crater and damage had four lobes. But, on the other hand, a tree 10 m from the epicenter was undamaged. There was no damage on the ground level at a distance up to about 1 km from the crater (only ground swing and jerking), but several high suspended electric wires were torn off. At large distances, there was unusual damage at the ground level, and even water pipes at a distance up to 15 km from the epicenter were torn off. During the explosion, in closed and undamaged rooms, in most cases different things flew with soft landings, and even some people were transported by a unknown force. Hollow plastic toys and electric lamp bulbs exploded. Inner windows were smashed while outer ones were undamaged. At a distance of about 10 km from the main crater, two more pits in the ground appeared simultaneously with the main crater. Soil was hurled, and there were light phenomena." (Ol'khovatov, A.

... Science Frontiers ONLINE No. 113: Sep-Oct 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Green Thunderstorms Anecdotes abound that exceptionally severe thunderstorms may appear to emit an eerie, sickeningly yellow-green light. Skeptics scoff at this notion. The excited observers were deluded, or they made it all up. This is, of course, the same knee-jerk response greeting UFO reports and accounts of many other anomalies. Thunderstorms, however, do have an objective existence. And it turns out that a few storm-watching meteorologists have also seen greenish thunderstorms. Such professional testimony is usually dismissed as due to the reflection of greenish ground vegetation by the storm clouds or, perhaps, the effects of sheets of hail preceding the storms. In 1995, F.W . Gallagher et al decided to settle the matter. They chased likely looking thunderstorms armed with a spectrophotometer. Many storms later, they proved, first of all, that some thunderstorms are definitely green. In fact, some gradually change from blue to green in the space of half an hour. Their ground observations, plus more spectrophotometer data taken from aircraft, refute the theory that the green color is from reflected vegetation. Hail may contribute to the green color but is not required. In sum, green thunderstorms really do exist, but no one yet knows where all the green comes from.

... tickle researcher and has even designed a (fake) tickling machine to test her subjects. She believes she knows why we laugh when we are subjected to gargalesis. ". .. the smiling and laughter encourage the tickler to continue. If tickling produced a negative facial expression, conspecifics would be far less likely to engage in it during playful bouts -- thus cutting off the development of combat skills that might have survival value." Translation : tickling-plus-laughter promotes the roughhousing needed to develop combat skills. Chimps, deer, and most young mammals engage in similar sport for the same purpose; but, as far as we can tell, without the laughing. The inability to self-tickle is hard to understand. After all, we can easily produce a knee-jerk reaction by tapping our own knee. Why can't we tickle our own ribs? Perhaps because our brain controls the action and also cancels out signals to pull away from the tickle and laugh. It could be the unpredictability of someone else's tickling that makes it so effective. Yet, when the tickler tickles our shoulder rather than our ribs, nothing happens. Strange! Why would evolution have given humans highly specific ticklish areas that respond only to other people and, to boot, makes us laugh? What survival value is there in this? In the end, Harris has to admit that tickling may not be adaptive at all, but rather an almost-neutral side effect genetically linked to some different characteristic that is adaptive.

... extremely dilute solutions under his electron microscope and found that some contain strange "ice" crystals, even though room temperature and pressure prevail. Called "IE crystals," they are produced through the action of ions. They are stable even at higher temperatures. Subsequently, an immunologist at the University of California at Los Angeles discovered that the IE crystals can stimulate parts of the immune system. Water containing these strange forms of ice show a hundred times more bioactivity than plain water. (Anonymous; "Homeopathy and IE Crystals," Spectrum , p. 18, November/ December 1998. Cr. E.

... a bicycle path to the right, and an open wide field...Suddenly I saw a bright green, phosphorescent...ball about the size of a medical training ball, that dropped to the ground behind the minibus...It fell to the road and rolled towards me . I knew immediately it was ball lightning, and from school physics I knew a car acts as a Faraday cage. So I kept my feet to the floor mat and grabbed the wheel with both arms. 3 to 5 seconds passed until the ball reached my car. It came in a straight line, with a slight deviation to the right (as seen from my position). When the ball caught my car at the right front side, it gave the vehicle a strong shock or jerk, as if I had driven against an obstacle . All that was on the right side of me lit up bright green -- the hood, the windscreen, the instrument panel, and even the padding. In the rear-view mirror I could observe that the ball went off the road behind my car. It rolled about 50 meters on the bicycle path, then went into the field and was gone after about 100 meters." This event was observed by people in the cars behind Urbanek. Later examination of the car found no physical damage, no magnetic anomalies, and no indications of contact with lightning.
