On April 4, the physics department at Columbia University held an unblinding party. For 100.9 days between January 13 and June 8, 2010, a detector 4,500 feet underground at the Laboratori Nazionali del Gran Sasso, in central Italy, had been collecting data. Following the protocol of a “blind” analysis, the data had instantly disappeared into […]
The Cosmos
My grandfather was interested in the Faust legend and I inherited the interest, though for the life of me I don’t know why it’s interesting and he died before I could ask him. Whatever it is, it has to do with trading your soul for certain bad kinds of knowledge, or with excessive curiosity leading […]
I’ve kept an eye on neutrinos ever since I heard, back in the mid-1980’s, that not enough of them were coming out of the sun; this sounded serious. It turned out that the sun was behaving itself but the neutrinos weren’t. On its way out of the sun, any given neutrino was changing into three […]
Some scientists make great discoveries. Some scientists provide the opportunity for other scientists to make great discoveries. Let us now praise one not-so-famous man. Victor Blanco assumed the directorship of the Cerro Tololo Inter-American Observatory (CTIO) in June 1967, just five months before the observatory opened. CTIO, a collaboration between U.S. and Chile, was an […]
The subject line in the e-mail was, “Congratulations, I think….” The message itself said, “Just read about Dark Matter finally outing itself.” “Huh?” I wrote back. “Haven’t you heard??? Dark Matter has been telescopically (is that a word?) observed!” The message came from a graduate student of mine during holiday break this past December. He […]
(This post is the third in a three-part series. The first and second appeared the past two Fridays.) “What can we as scientists do to better communicate science to the general public?” This question didn’t stump me, but, I admit, the answer did elude me at first. I started talking about how writers are dependent on […]
“What can we do about high school physics textbooks?” The question, I admit, stumped me. Not in the way that a question about whether gravity exists in other universes would stump me. That question I wouldn’t be able to answer because there isn’t an answer; the existence of other universes is speculative. This question, however, […]
(This post is the first in a three-part series. “Talking Universe Blues” will continue over the next two Fridays.) “Does gravity exist in other universes?” The question, I admit, stumped me. Did she—fourth row, on the aisle—mean that gravity might be leaking into our universe from a parallel universe? Unlikely. Her puzzled, perhaps lost, expression didn’t […]
