This article reports that 223 out of 243 aircraft in the study produced contrails and that the researchers produced a model that predicts contrails correctly 92 percent of the time (but doesn’t predict their duration). Based on the article, I propose the simplest possible model: Always predict a contrail. You’ll be right 223/243 (92 percent) […]

In your article, you describe Einstein’s negative reaction to Newton’s proposition that gravity acts instantaneously on two objects. The notion of simultaneous (if not instantaneous) properties in physics is one of the basic notions of quantum physics. I do not feel that Einstein’s “particle-like” description of light makes him (even “ironically”) “a builder of the […]

In this article you mention that Lyme disease is the most common “insect-borne” disease in the United States. Since Lyme disease is spread by ticks, and ticks have eight legs and are arachnids, Lyme disease is not insect-borne. Anne Van Aller Woodbine, Md.

I found this article quite fascinating. In 1973, my colleagues and I showed that rats would respond with the future in mind. Specifically, rats will make a response that results in one immediate electric shock, as long as that punished response is instrumental in avoiding five identical shocks programmed to occur 10 seconds later. It […]

Just because chemical equipment can measure parts per trillion doesn’t necessarily mean that they have any biological significance. If you took one pill of Tylenol and dissolved in an olympic-size swimming pool, that would roughly be 1 part per billion. One part per trillion would be one pill in 1,000 swimming pools. My point is […]
