1. THE COPENHAGEN CONSPIRACY: IS QUANTUM MECHANICS WRONG?

Today's issue of Science has a NewsFocus article about physicist Anthony Valentini of Imperial College London and his attempt to straighten out the mess left by Bohr and Heisenberg 80 years ago. Valentini is co-author with Guido Bacciagaluppi of "Quantum Theory at the Crossroads," to be published later this year. It continues a debate that has gone unresolved. It was put on hold because scientists were just too busy using quantum mechanics, to worry about why it works. Measured by the incredible range of phenomena it permits us to calculate and the technologies it has spawned, quantum mechanics must surely be the most successful scientific theory in history. It is, unfortunately, also wrong. Valentini's theory could spawn a revolution in physics.

2. PEOPLE: ALMOST 7 BILLION IS ALREADY WAY TOO MANY.

When was it that the media stopped mentioning population? We read almost daily headlines about global warming from CO2 in the atmosphere. It's our own fault, were told; we caused it by burning fossil fuels; we should have been driving fuel-efficient automobiles, living closer to work, and using nuclear and solar power generation. That's all true, but it won't help if we just let the population grow. Name a single world problem that isn't made worse by population growth. Biologist Paul Ehrlich shook us awake in 1968 with "The Population Bomb," but in 1980 he lost a public wager with University of Maryland economist and libertarian Julian Simon over the price of minerals. Ehrlich lost. Today, although population has risen to double that in 1968, the media avoids even mentioning it. The June issue of Scientific American, however, has "Population and Sustainability" by Robert Engelman of Worldwatch. Everyone should read it.

3. HUNGER: MORE THAN A BILLION PEOPLE ARE MALNOURISHED.

Most of them are in Africa. A review of "Enough", a book by Roger Thurow and Scott Kilman, in Sunday's Financial Times, blames the problem on agriculture. Its clear from the numbers, however, that the real culprit is uncontrolled growth of population, which has led to proliferation of small, unproductive shambas.

4. ALTERNATIVE MEDICINE: $2.5 BILLION LATER, STILL NO CURE

More than a third of all Americans use some form of alternative health remedies. This week, Associated Press reporter Marilynn Marchione has written a series of articles on the failure of alternative remedies from herbals to acupuncture to demonstrate any measurable efficacy in placebo- controlled double-blind studies conducted for NIH. The possible exception is ginger capsules to treat nausea from chemotherapy. WN strongly opposed the creation of the National Center for Complementary and Alternative Medicine at NIH when it was created in 2000, on the grounds that it would be seen as evidence that the medical world was taking alternative and complementary medicine seriously. It was. Nevertheless, when asked later to serve as the lone physicist on the steering committee, I agreed. The Problem had simply become too large to ignore. The director Stephen E. Straus was both rigorous and fair, and although half the steering committee members were from the alternative world, there was a consensus on most issues. Tragically, Stephen Straus died of brain cancer in 2007. That desperate people still fall for these sham cures is also tragic.
