Where the known meets the unknown is where science begins

At a February 12, 2002, news briefing, Secretary of Defense Donald Rumsfeld explained the limitations of intelligence reports: “There are known knowns. There are things we know we know. We also know there are known unknowns. That is to say, we know there are some things we do not know. But there are also unknown unknowns, the ones we don’t know we don’t know.”

Rumsfeld’s logic may be tongue-twisting, but his epistemology was sound enough that he was quoted twice at the World Summit on Evolution. The June conference, hosted by San Francisco University of Quito, was held on the Galápagos island of San Cristóbal, where Charles Darwin began his explorations. Rumsfeld’s wisdom was first invoked by University of California at Los Angeles paleobiologist William Schopf, who, in a commentary on a lecture on the origins of life, asked: “What do we know? What are the unsolved problems? What have we failed to consider?”

Creationists and outsiders often mistake the latter two categories for signs that evolution is in trouble, or that contentious debate between what we know and do not know means that the theory is false. Wrong. The summit revealed a scientific discipline rich in data and theory as well as controversy and disputation over the known and unknown. (continue reading…)

The curious case of acupuncture

John Marino was the most driven man I ever met, a monomaniac on a mission to break the U.S. transcontinental cycling record — which he did in 1980, covering the 3,000 miles in 12 days, three hours. I wanted to be like John, so that year I took up serious cycling. In addition to pedaling hundreds of miles a week with him, I followed his training regimen of vegetarian meals, megavitamin dosing, fasting, colonics, mud baths, iridology (iris reading), negative ions, chiropractic, massage and acupuncture.

Although most of the nostrums I tried were useless, I noted with interest (because he beat me) that Jonathan Boyer, the winner of the 1985 Race Across America (co-founded by Marino and me), had a Chinese acupuncturist on his support crew. Given the successes of Marino and Boyer, it seemed possible that there might be a biomedical connection.

Traditional Chinese medicine holds that a life energy called Qi (“chee”) flows through meridians in the body; each of the 12 main meridians represents a major organ system. On these 12 meridians are 365 acupuncture points, one for each day of the year. When yin and yang are out of balance, Qi can become blocked, leading to illness. Inserting needles at blocked points — believed to number about 1,000 — supposedly stimulates healing and health. (continue reading…)

Can nutritional supplements, biotechnology and nanotechnology help us live forever?

As a skeptic, I am often asked my position on immortality. “I’m for it, of course,” is my wiseacre reply.

Unfortunately, every one of the 100 billion humans who have ever lived has died, so the outlook does not bode well. Unless you follow the trend line generated by Ray Kurzweil and Terry Grossman in Fantastic Voyage: Live Long Enough to Live Forever (Rodale, 2004): “The rate of technical progress is doubling every decade, and the capability (price performance, capacity, and speed) of specific information technologies is doubling every year. Because of this exponential growth, the 21st century will equal 20,000 years of progress at today’s rate of progress.” Within a quarter of a century, the authors say, “nonbiological intelligence will match the range and subtlety of human intelligence,” then “soar past it because of the continuing acceleration of information-based technologies, as well as the ability of machines to instantly share their knowledge.” Biotechnologies, such as designer drugs and genetic engineering, will halt the aging process; nanotechnologies, such as nanorobots, will repair and replace cells, tissues and organs (including brains), reversing the aging process and allowing us to live forever.

9/11 has generated the mother of all conspiracy theories

Noted French left-wing activist Thierry Meyssan’s 9/11 conspiracy book, L’Effroyable Imposture, became a best-seller in 2002. But I never imagined such an “appalling deception” would ever find a voice in America. At a recent public lecture I was buttonholed by a Michael Moore–wannabe filmmaker who breathlessly explained that 9/11 was orchestrated by Bush, Cheney, Rumsfeld and the Central Intelligence Agency as part of their plan for global domination and a New World Order. That goal was to be financed by G.O.D. (Gold, Oil, Drugs) and launched by a Pearl Harbor–like attack on the World Trade Center and the Pentagon, thereby providing the justification for war. The evidence is there in the details, he explained, handing me a faux dollar bill (with “9-11” replacing the “1,” a picture of Bush supplanting that of Washington) chockablock with Web sites.

In fact, if you type “World Trade Center conspiracy” into Google, you’ll get more than 693,000 hits. From these sites, you will discover that the Pentagon was hit by a missile; that U.S. Air Force jets were ordered to “stand down” and not intercept Flights 11 and 175, the ones that struck the twin towers; that the towers themselves were razed by demolition explosives timed to go off soon after the impact of the planes; that a mysterious white jet shot down Flight 93 over Pennsylvania; and that New York Jews were ordered to stay home that day (Zionists and other pro-Israeli factions, of course, were involved). Books also abound, including Inside Job, by Jim Marrs, The New Pearl Harbor, by David Ray Griffin, and 9/11: The Great Illusion, by George Humphrey. The single best debunking of this conspiratorial codswallop is in the March issue of Popular Mechanics, which provides an exhaustive point-by-point analysis of the most prevalent claims.

What do the Beatles, the Virgin Mary, Jesus, Patricia Arquette and Michael Keaton all have in common?

In September 1969, as I began ninth grade, a rumor circulated that the Beatles’ Paul McCartney was dead, killed in a 1966 automobile accident and replaced by a look-alike. The clues were there in the albums, if you knew where to look.

Sgt. Pepper’s Lonely Hearts Club Band’s “A Day in the Life,” for one, recounts the accident: He blew his mind out in a car / He didn’t notice that the lights had changed / A crowd of people stood and stared / They’d seen his face before / Nobody was really sure if he was from the House of Lords. The cover of the Abbey Road album shows the Fab Four walking across a street in what looks like a funeral procession, with John in white as the preacher, Ringo in black as the pallbearer, a barefoot and out-of-step Paul as the corpse, and George in work clothes as the gravedigger. In the background is a Volkswagen Beetle (!) whose license plate reads “28IF” — Paul’s supposed age “if” he had not died. (continue reading…)
