What makes oxygen oxygen and not, say, iron is not what these two elements are made of-both kinds of atoms have nuclei made of protons and neutrons, with a surrounding cloud of electrons. It's how many of these basic building blocks their nuclei contain. The fact that an oxygen atom has 8 protons, in particular, and iron 26 largely explains why you can breathe one and make a frying pan from the other...
...with great fanfare Monday that experts at the Lawrence Livermore National Laboratory, in California, announced they, along with colleagues at Russia's Joint Institute for Nuclear Research, in Dubna, have produced an atom with 118 protons. Three atoms, actually. And all it took was smashing "bullets" of calcium at a target of Californium about 10,000,000,000,000,000,000 times...
Busy giving interviews and meeting with United Nations representatives since Monday’s incident, Jeffrey G. Lewis, the executive director of Harvard’s Managing the Atom (MTA) Project, added instructions to his voice mail message for press queries related to North Korea...
...Science department has quite a few faculty superstars. After a leave of absence last year due to illness, Everett I. Mendelsohn—a History of Science fixture for 45 years—has returned to teach a junior seminar (History of Science 90w, “The Atom Bomb in History and Culture”) and a freshman seminar (43q, “Historian and the Genes–From Mendel to Human Clones”). Students can enjoy his pseudo-British accent (à la Reverend Gomes) and bathe in his deep knowledge of all things Larry Summers.An...
...first of those hints comes from the universe-wide flash of light that followed nearly half a million years after the Big Bang. Before that flash occurred, according to the widely accepted "standard model" of cosmology, our entire cosmos had swelled from a space smaller than an atom to something 100 billion miles across. It was then a seething maelstrom of matter so hot that subatomic particles trying to form into atoms would have been blasted apart instantly and so dense that light couldn't have traveled more than a short distance before being absorbed. If you could somehow live...
