This 20,000-kilowatt turbine will have twice the output of the […]

“Physics bedrock cracks, sun shines in” says that solar neutrinos oscillate between different flavors on the trip to Earth and that those taking a longer path have more time to oscillate into kinds of neutrinos that the sun doesn’t produce. Do the scientists note a variation in neutrino types based on the eccentricity of Earth’s […]

Thinking of Zero
For anyone deeply interested in logic and the history and philosophy of zero, Hossein Arsham of the University of Baltimore offers an thought-provoking Web-based discussion of such topics as the meaning of division by zero, the role of zero in limits and divergent series, and the concept of zero as a void.

HUGE ELETROMAGNET INSTALLED AT LEIDEN A huge electromagnet weighing 14 tons, about two-thirds as much as a street car, just erected at Leiden, Holland, by the Siemens Halske Company of Berlin, will enable scientists to wrench atoms apart as never before. This marks the realization of a dream of the late Dr. H. Kammerlingh Onnes, […]

Your news piece was timely. But if we see that big quake, most likely Washington State will be in worse shape. Recent comments by seismologists, volcanologists, and oceanographers concerning a large quake on that major fault line and/or a big volcanic eruption would be something out of Biblical times. Take a look at the Washington […]

That is a neat little recycle program described in “New test traces underground forest carbon.” As fast as the CO2 comes out of the ground, the tree grabs the carbon by photosynthesis and leaves two oxygen atoms in the atmosphere. A portion of the carbon is stored until the wood rots or burns. Some carbon […]

In the space of a single paragraph, you report that the National Academy of Sciences and the United Nations conclude that human activity “very likely” has caused global warming and that “uncertainties remain about the role of human-generated gas emissions.” One can’t have it both ways. Given the uncertainties involved, President Bush is following the […]

Geo Name Game

The U.S. Geological Survey’s Geographic Names Information System (GNIS) contains data about nearly 2 million geographic features in the United States. Just enter a name or any […]

TWIN ALBINO ROBINS HATCHED WITH NORMAL BIRD Two albino robins, highly interesting and rather rare oddities in the bird world, have been watched from hatching to early maturity at the home of H.D. Shaw of Grinnell, Iowa, and had their pictures taken by Miss Cornelia Clarke, nature photographer. The nest was built high up on […]

With reference to the opinion that hemophiliacs might have expected to feel better and been less likely to treat themselves for internal bleeding following a form of gene therapy, I can only object to the suggestion that hemophiliacs can feel-better themselves out of an internal bleed. As a mother and grandmother of hemophiliacs who coped […]

The interesting article “Survey probes cosmos from near to far” set me to tilting at windmills. Even before it’s completed, the professional astronomers managing the Sloan Digital Sky Survey should enlist amateur astronomers as asteroid hunters in a way similar to how they’re mobilized by the SETI@home project to search for intelligent signals from space. […]

It was a bit of a shame that the fossil-trackway site pictured on the cover of the June 9 issue was not identified, as it is one of the more remarkable ones ever uncovered in North America . The tracks shown are a few of hundreds across the floor of a quarry near Culpeper, Va. […]
