November 2 – 6, 2015 Our identities include our birth dates, says Sally. So what if you don’t have one? Helen walked the Cotswold Way and entered the liminal state of all pilgrims. How happy are clams, really, asks Cameron. Guest Nicholas Suntzeff reminisces about the old tensions between Chile and Bolivia, and how losses…
Cassandra wrote a post about the landlocked Bolivian navy in which she explained, in passing, that Bolivia once had a coast but lost it to Chile in the War of the Pacific. One of the comments on that post, by guest poster Nick Suntzeff, was a post in itself and we thought you’d like to…
I received an email the other day from Nicholas Suntzeff, the director of the Astronomy Program at Texas A&M as well as a friend. (Readers might remember that he has published two guest posts with LWON.) His email was in fact a series of emails that he thought I might enjoy. It started with a…
One evening during a recent visit to Santiago, Chile, I went to dinner with two colleagues. Afterward, as I descended the stairs of the Metro to cross Providencia Avenue, I saw a young girl, no more than five years old, wrapped in a dirty blanket, sitting on the ground. She was holding out a shoe…
Happy Birthday to us, we’ve just turned two. We’re bigger: we’ve added three new Persons of LWON. And we’ve matured, that is, we stopped looking so much at our own bellybutton and are more aware of the intelligent, thoughtful Commenters of LWON. So for our birthday celebration, we’ll look back at the year and not…
This year’s Nobel Prize in Physics was, in a way, a foregone conclusion. The 1998 discovery by two teams of scientists that the expansion of the universe is accelerating—under the influence of something that scientists have shruggingly come to call dark energy, which later studies have revealed to comprise 72.8 percent of the universe—was one…
The news of a detection of faster-than-light speed neutrinos by the OPERA experiment stunned the physics and astronomy community last week. I read the paper, and I listened to the talk from Geneva over the Web. This is seriously weird stuff! Faster-than-light speed neutrinos!? The talk was filled with wonderfully arcane geodetic methods for measuring…
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…
