What’s In A Label?

Conservative. Liberal. We act as if we know what these labels mean. Conservatives are traditionalists, fiscally opposed to anything that smacks of gambling, private, often religious, and pedantic on what they consider “appropriate” in either government or personal conduct. Liberals, on the other hand, are often taken for progressive, willing to spend social capital to repair perceived problems, tolerant, agnostic if not atheist, and overly-concerned with a definition of justice that ought to be all-encompassing rather than what they perceive as sinecure for the privileged. Well. Over on Facebook I posted a brief quote (my own) to boil down the actual underlying distinctions. Conservatives are those who don’t like what other people are doing, Liberals are those who don’t like what other people are doing to other people. It was meant to be taken as humorous. But I’m not being entirely flip here. When you look at it, and try to define the common factor in much that passes for conservative posteuring—of any country, any background, anywhere—it always comes down to one group trying to stop another group from Doing Things We Don’t Approve. I heard a news report this morning (on NPR—I unabashedly don’t pay attention to any other news source, I find them all utterly biased) from Pakistan about the university scene there, and one bit caught my attention—at a campus in Punjabi, conservative students who find men and women sitting too close together interfere and move them apart. At a game of Truth or Dare, conservative students pulled participants out and beat them. How does this apply here? Well, here’s a clip from P.Z. Meyers’ Pharyngula to illustrate: Rising Sun School in Maryland has the standard default take-it-for-granted attitude that Christianity is just fine — there’s the usual well-funded and usually teacher-promoted evangelical groups, like the Fellowship of Christian Athletes — and when one student tried to form a club for non-religious students…well, you can guess what happened.

Overdosing on homeopathic drugs?

I recently ran across this 2009 article about a young woman who apparently tried to overdose on a homeopathic drug called "Traumeel." I'm not trying to make light of a sad situation, but only to use this example to illustrate the widespread ignorance regarding homeopathy. A good description of homeopathy was given by James Randi in his 2001 talk at Princeton: Note the math lesson beginning at the five minute mark. Homeopaths argue that the more dilute a solution is, the more powerful it is. At the 7:30 mark, Randi explains that a "30X" solution is so dilute that it reaches the "number of no return." "30X" is so dilute that it is the equivalent of placing 15 drops of water in a container more than 50 times the size of the Earth. Other homeopathic solutions are available in 1,500x solutions. How dilute is that? It's the equivalent of (12:00) smashing one grain of rice into a sphere of water the diameter of the solar system, shaking it up, and then further diluting that same solution 2 billion more times in an equivalent sized sphere. To bring the matter full circle, at the ten-minute Randi explains how he ate two entire packages of a popular homeopathic sleeping pill (sold at nationwide pharmacies) without overdosing. Believe it or not, the active ingredient was caffeine. At 13:30, Randi characterizes the people who sell these "medicines" "swindlers, liars, cheats, frauds, fakes, criminals." For more on homeopathy, now used by five million people world-wide, consider the many statistics in my earlier post and consider viewing this video by Richard Dawkins. At the 3-minute mark, Dawkins wryly notes that if water really had "memory" of the ingredients it formerly contained (as fans of homeopathy contend), what should we make of the fact that "in each glass of water we drink, at least one molecule has passed through the bladder of Oliver Cromwell." At the 5-minute mark, when discussing whether homeopathy theory is plausible, the Director of a brand new English hospital (who actually was trained as a rheumatologist) unleashes this whopper of a quote: "The fact is that I couldn't stop what I do even if I wanted to. My patients wouldn't let me. They say it helps." BTW, check out the not-so-impressive medical research by the manufacturer of Traumeel. The manufacturer's recipe of a British narrator uttering big scientific words is featured in this video, and it is doubtless irresistible to many potential purchasers. Here's a bit of much needed skepticism regarding Traumeel. Whatever you do, don't utter the word "placebo" to anyone who pays big money for these "medicines."

Bobby McFerrin illustrates the simple beauty of the pentatonic scale

This is fun--actually delightful. Bobby McFerrin plays the audience, and they produce a pentatonic baseline for McFerrin's improvising.
