Music, Metals, and Learning
The Mind’s Eye is available now in English, German, Dutch, and Portuguese (Brazil), with more translations on the way. Dr. Sacks discusses the book, and many other topics, on his new YouTube channel.
“The Music Never Stopped,” the independent feature film based on Dr. Sacks’s essay “The Last Hippie,” made its debut at the Sundance Film Festival this month, and will open in theaters in March. It is a moving story about the healing power of music, with a soundtrack featuring the Grateful Dead, Bob Dylan, the Beatles, the Rolling Stones, and Crosby, Stills and Nash.
Meanwhile, “Molly Sweeney,” the Brian Friel play inspired by “To See and Not See” (another of the essays in An Anthropologist on Mars) opens tonight at the Irish Repertory Theatre in New York City, with performances through March 13.
And on February 10, at New York’s 92nd St. Y, Dr. Sacks will be in conversation with Jonathan Weiner, discussing Weiner’s latest book, on the science of immortality.
Dr. Sacks will be speaking at two conferences this spring: WNET’s Celebration of Teaching and Learning (New York, March 18-19) and, for the metallurgically inclined, the InternationalMinor Metals Conference (Philadelphia, May 4-6). What exactly is a “minor metal”? See our Footnote of the Month.
Finally, we want to share with you Dr. Sacks’s New York Times article on New Year’s resolutions, and we wish you many good learning experiences, whatever they may be, in 2011.
PS: Did you know you can follow Dr. Sacks on Twitter and Facebook? Our favorite tweet this month was about the world’s smallest Periodic Table. And here’s a bonus for squid lovers.
Footnote of the Month: January 2011
What are the “minor metals,” so-called? They are metals not traded on the London Metal Exchange, but they nonetheless have a wide range of uses essential to modern life. Some of them fall into a category called the rare earth elements–which are not especially rare, but were very difficult for early chemists to separate. No fewer than four of these are named after the tiny village of Ytterby, Sweden, where they were first discovered: yttrium, terbium, erbium, and ytterbium. The other minor metals have lovely names, too: antimony, arsenic, beryllium, bismuth, cadmium, calcium, cerium, chromium, cobalt . . . and on through tantalum, tellurium, titanium, tungsten, vanadium, and zirconium. Tom Lehrer, anyone?
In Uncle Tungsten, Dr. Sacks talks about his first encounters with the rare earths.
I think I first heard of the rare earths from my mother, who was a chain smoker and lit cigarette after cigarette with a small Ronson lighter. She showed me the “flint” one day, pulling it out, and said it was not really flint, but a metal that produced sparks when it was scratched. This “mischmetal”—cerium mostly—was a mishmash of half a dozen different metals, all of them very similar, all of them rare earths. This odd name, the rare earths, had a mythical or fairy-tale sound to it, and I imagined the rare earths as not only rare and precious, but as having special, secret qualities possessed by nothing else.
Later Uncle Dave told me of the extraordinary difficulty which chemists had had in separating the individual rare earths—there were a dozen or more—for they were astoundingly similar, at times indistinguishable in their physical and chemical properties. Their ores (which for some reason all seemed to come from Sweden) never contained a single rare-earth element, but a whole cluster of them, as if nature herself had trouble distinguishing them. Their analysis formed a whole saga in chemical history, a saga of passionate research (and frequently frustration) in the hundred years or more it took to identify them.
