The Essential Oils Desk Reference lists cinnamon as one of the oils to use for diabetes. Coincidence? I think not. Ancient natural remedies are very effective if you use high-grade therapeutic oils. More testing should be done with natural “medicines,” even though this wouldn’t be profitable for the drug industry. Tom E. KlassenNoblesville, Ind. Chemist […]

It’s pitiful to see supposedly objective scientists fantasizing that there’s a “fact that life could be widespread” because they’ve found organic polycyclic aromatic hydrocarbons in space. Even if researchers found all the amino acids floating in space, it would be like finding a pile of bricks and other building materials and imagining they could form […]

Skins game I know some people who carefully shield their bodies from the sun with sunscreen and clothing, and their skin is extremely pale. But if tanning acts as a protector (“Sunny Solution: Lotion speeds DNA repair, protects mice from skin cancer,” SN: 3/6/04, p. 147: Sunny Solution: Lotion speeds DNA repair, protects mice from […]

I described everything in this article almost 50 years ago in The City and the Stars (1956, Harcourt, Brace, and World). See chapter 6: “He set up the matrix of all possible integers, and started his computer stringing the primes across its surface as beads might be arranged at the intersections of a mesh. Jeserac […]

This article focused exclusively on the conversion efficiency of the solar cells. To my way of thinking, the important parameter is not output power versus input power but output power per dollar cost. The size of the arrays is generally not the deciding item. If their efficiency were only 10 percent, but they cost 10 […]

Like physicists, mathematicians have always been divided into theorists and experimentalists. And, as with the physicists, the two groups of mathematicians have not gotten along very well. Still, in physics, there has always been an understanding that both groups are necessary, whereas during the past century or so, it has been possible to pretend that […]

This article reminded me of the old quote: “A fishing lure is any combination of metal, plastic, wood, feathers, hair, or other manmade or natural material attached to a hook (or hooks) and designed to attract fishermen.” To wit: Decades ago, to impress an office associate who was a trout-fishing traditionalist as to how random […]
