About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

Science Frontiers ONLINE No. 44: Mar-Apr 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects How The Incas Worked Stone Inca stonework is famous for its large stones (some over 100 tons), which are fitted so precisely that "a knife cannot be inserted into the joints." An aura of mystery has always hung about the great "walls" at Saqsaywaman and Ollantaytambo (spellings vary). How could the Incas have quarried, dressed, transported, and lifted such huge stones? As usual with such remarkable ancient structures, the overzealous have proposed antigravity devices, stone-softening agents, and similar wild notions. In truth, as J. Protzen relates in the subject article, Inca stonemasonry was surprisingly unsophisticated and yet efficient, although some mysteries remain. Protzen has spent many months in Inca country experimenting with different methods of shaping and fitting the same kinds of stones used by the Incas. He found that quarrying and dressing the stones were not problems at all using the stone hammers found in abundance in the area. Even the precision-fitting of stones was a relatively simple matter. The concave depressions into which new stones were fit were pounded out by trial and error until a snug fit was achieved. Protzen's first-hand experience is impressive and convincing. Certainly he required no radical solutions. The problems that Protzen was not able to solve to his satisfaction involved the transportation and handling of the large stones. The fitting process necessitated the repeated lowering and raising of the stone being fitted, with ...

Science Frontiers ONLINE No. 50: Mar-Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects "HIGH"-TECH FARMING AT TIAHUANACO One of Tiahuanaco's (or Tiwanaku's ) many puzzles has been how food for such a large city was grown at an altitude of circa 3,850 meters (12,600 feet) in the frosty, windswept Bolivian Andes. This problem along with the fabulous stonework and extensive ruins have precipitated theories involving extraterrestrial visitors and an age for the site in the hundreds of thousands of years. At least the food-supply puzzle now seems to be in hand. Stereoscopic aerial photographs show in startling detail: ". .. immense, curvilinear platforms of earth...these fields form elevated planting surfaces ranging from five to 15 meters wide and up to 200 meters long...Extensive and nearly continuous tracts of these fields -- all of which have been abandoned for centuries -- run from the edge of Lake Titicaca to about 15 kilometers inland, and form virtually the only topographic relief in the broad, gradually sloping plain." Some of the raised fields are remarkably sophisticated in design. At the base is a layer of cobblestones for stability. These are covered by a 10-centimeter layer of clay. On top of the clay are three distinct layers of sorted gravel; all capped by rich organic topsoil. These fields were simultaneously an aquifer for the fresh water percolating down from the surrounding hills and a barrier to the brackish water from Lake Titicaca ...

Science Frontiers ONLINE No. 52: Jul-Aug 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Costa rica's neglected stone spheres Books and articles on Stonehenge, the Easter Island statues, and the Egyptian pyramids are legion. Granted that these structures are important and intriguing, we still ask why Costa Rica's meticulously wrought stone spheres are languishing in the wings of science. They epitomize exquisite workmanship. Such geometric perfection rendered in granite is remarkable-- -for any ancient culture. Lastly, the stones' purpose completely escapes us. Why strew such masterpieces of stoneworking around and even buried under the dark jungle floors? M.T . Shoemaker also wonders about these things in a nice recapitulation of the stone-sphere mystery. His compilation of facts and figures only impels us to learn more about the spheres and what their shapers had in mind. The spheres are found on the Diquis River delta, near the Pacific coast of southern Costa Rica. Stone-sphere sizes range from an inch to 8 feet in diameter. At least 186 spheres have been recorded in the literature. Surely many more were destroyed and other remain undiscovered. No local source exists for the granite; and no stone-working tools have been found near the spheres. "The best spheres are perhaps the finest examples of precision stonecarving in the ancient world." The maximum circumference error in a 6-foot, 7-inch diametre sphere in only 0.5 inch, or 0.2 %. The spheres are often grouped ...

... Science Frontiers ONLINE No. 82: Jul-Aug 1992 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A CONNECTICUT SOUTERRAIN?Souterrains, such as that figured, are megalithic constructions usually considered to be exclusively of European origin. This look-alike, at Montville, CT, could indicate pre-Columbian contacts. Here are some details: "This underground site is built into a rocky hillside in an isolated region. A 37 ft. passage of straight-sided drywall stonework is interrupted after 8 ft. by a 3 ft. collapsed section. It then continues on for 20 ft. to a little corbelled chamber whose end wall is cut into a roughly quarried and levelled ledge. On the slope around the souterrain are about 100 cairns, some carefully constructed; others appear to be the result of field clearing." (Anonymous; "An Arm-Chair Field Trip," NEARA Journal, 26:87, Winter/Spring 1992.) NEARA = New England Antiquities Research Association. Comment. The prevailing explanation of such New England lithic structures is that they were simply colonial root cellars or something of the kind. The structure figured is certainly a very ambitious root cellar! Reference. Our handbook Ancient Man investigates these New England chambers in some detail. For more on this book, visit: here .

... as well as spiral and meandertype carvings. There are even a few cup-and-ring markings, like those so prevalent in northern Europe. Most curious are the so-called "axle-type" monuments, which consist of a central hub with two straight projecting arms. Early in 1981, the monument shown in the sketch was found in the Immidir district. It is basically V-shaped, with two sets of "auxiliary" arms, one V-type and one axle-type, both of which are detached from the hub like "spare parts." The tips of the north-south arms in the sketch are about 75 meters apart. Clearly, orientation was important to the builders of the monuments, but the asymmetry and auxiliary arms are puzzling. The stonework in these central Saharan monuments is good. Dates are elusive, but all indications are that the sites are ancient.

... , this artifact depicts a trousered, bearded man of European countenance, who is missing one arm and a foot. Petersen asserts that the artifacts have no affinities with American Indian artifacts: rather they have a European flavor. What can one make out of all this? Petersen is only able to state: "Although the site is undoubtedly human-made, its function, antiquity and cultural attribution cannot be precisely specified on the basis of the unique characteristics of both the artifacts and the cist. Tentative interpretations allow suggestion that it is attributable to some portion of the historical period, a European cultural tradition, and probably is contemporaneous with or postdates local stone working at the site." In other words, we could have anything from a pre-Columbian European contact to rock doodling by Colonial stoneworkers.

... 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. (Gallin, Lenore; "The Prehistoric Towers of Sardinia," Archaeology, 40:26, September/October 1987.) Reference.

... Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Granite-working In Ancient Egypt The ancient Egyptians cut and shaped limestone with ease and alacrity. 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. ...
