Uncle Tungsten

Uncle-TungstenUncle Tungsten: Memories of a Chemical Boyhood (2001)
Paperback, Vintage Books, ISBN 0-375-70404-3
Hardcover, Alfred A. Knopf, ISBN 0-375-40448-1
A memoir of growing up in World-War-II England as part of an extraordinary scientific family.












Uncle Tungsten
Sacks, a neurologist perhaps best known for his books Awakenings (which became a Robin Williams/Robert De Niro vehicle) and The Man Who Mistook His Wife for a Hat, invokes his childhood in wartime England and his early scientific fascination with light, matter and energy as a mystic might invoke the transformative symbolism of metals and salts. The “Uncle Tungsten” of the book’s title is Sacks’s Uncle Dave, who manufactured light bulbs with filaments of fine tungsten wire, and who first initiated Sacks into the mysteries of metals. The author of this illuminating and poignant memoir describes his four tortuous years at boarding school during the war, where he was sent to escape the bombings, and his profound inquisitiveness cultivated by living in a household steeped in learning, religion and politics (both his parents were doctors and his aunts were ardent Zionists). But as Sacks writes, the family influence extended well beyond the home, to include the groundbreaking chemists and physicists whom he describes as “honorary ancestors, people to whom, in fantasy, I had a sort of connection.” Family life exacted another transformative influence as well: his older brother Michael’s psychosis made him feel that “a magical and malignant world was closing in about him,” perhaps giving a hint of what led the author to explore the depths of psychosis in his later professional life. For Sacks, the onset of puberty coincided with his discovery of biology, his departure from his childhood love of chemistry and, at age 14, a new understanding that he would become a doctor. Many readers and patients are happy with that decision.

CERN completes transition to lead-ion running at the LHC

Four days is all it took for the LHC operations team at CERN to complete the transition from protons to lead ions in the LHC. After extracting the final proton beam of 2010 on 4 November, commissioning the lead-ion beam was underway by early afternoon. First collisions were recorded at 00:30 CET on 7 November, and stable running conditions marked the start of physics with heavy ions at 11:20 CET today.
“The speed of the transition to lead ions is a sign of the maturity of the LHC,” said CERN Director General Rolf Heuer. “The machine is running like clockwork after just a few months of routine operation.”
