1. SCIENCE MAGAZINE: REVIEWING THE 259th DECADE OF SCIENCE.

This week the news staff of Science is "stepping away from the trees for a look at the forest." I'm a little late getting WN out because I couldn't stop reading. The incredible, and somewhat frightening, rate of scientific progress prompted me to go back and look at the first decade of science. Thales of Miletus used the occasion of a full solar eclipse that passed over Melitus to state the first law of science: for every observable effect, there is a physical cause. The occasion is taken to mark the birth of science, but it also marks the death of superstition.

2. CANCUN: LOOKING FOR PROGRESS IN THE SECOND DERIVATIVE.

China pledged to reduce the rate at which its emissions are increasing. Well, at least they're talking, but emission rate is a second-order problem. First we should worry about the worlds uncontrolled fertility rate. Reduce the population and emissions will be reduced proportionately. It is the only emissions-control policy that is guaranteed to work. Chinas leaders know more about the population problem than anybody, having undertaken the courageous one-child policy to avert an inevitable catastrophe from Maos wacky economic theories. The mere mention of population inevitably draws comments that the industrialized nations have already achieved zero population growth and warnings by futurists such as Fred Pearce about a "population crash." The bitter truth is that Earth's population must be reduced.

3. ARSENIC: NASA EXPLORES INNOVATIVE WAYS TO HYPE RESEARCH.

"The definition of life has just expanded," declared Ed Weiler, NASA Associate Administrator for Science. An extremophile bacterium, adapted to tolerate the relatively high concentration of arsenic found in Mono Lake in the California desert, has been found. Arsenic is in the same column of the periodic table as phosphorus, and would be expected to have similar chemical properties. It would not be totally surprising if arsenic sometimes substitutes for phosphorus in the Mono Lake bacterium. It is also not totally surprising that, coming out of NASA, Weilers remarks set off a frenzy of media reports that an extraterrestrial life form had been discovered.

4. HOMEOPATHY: FUNDAMENTAL LAWS OF NATURE TAKE PRECEDENCE.

The Science and Technology Committee of the UK Parliament released a report urging the government to withdraw funding and licensing of homeopathy. It is unlikely to happen; even the Queen has her own personal homeopathist. This year is the 200th anniversary of Samuel Hahnemann's "Organon of the Medical Art." The prevailing philosophy of medicine at the time was "vitalism, the belief that life involves some spiritual essence. "Medicinal energy," Hahneman wrote, "is most powerful when it communicates nothing material." He was unaware of the extent to which he achieved this ideal by sequentially diluting his medications. It would be another 50 years before Loschmidt determined Avogadros number. It is now clear that Hahnemann was many dilutions beyond the dilution limit. Last week WN commented on the mistaken belief that cell phone radiation causes cancer. The photon energy in the microwave region of the spectrum is only about 1 millionth of the energy required to create a mutant strand of DNA, which is the initiation of cancer. There is no need to go any further. Epidemiology is expensive, time-consuming, and prone to statistical errors and faulty recall.
