...Seoul insists its scientists were not conducting weapons research and that it has fully disclosed its activities. But there is nagging evidence that the country has for decades periodically carried out clandestine experiments to gain know-how that would allow it to quickly develop atomic weapons, specifically through the production of plutonium and enrichment of uranium. (Much of the controversy surrounding Iran's nuclear program concerns efforts to enrich uranium.) Although those radioactive elements can be found in peaceful nuclear programs (with 19 reactors supplying 40% of its electricity, South Korea relies heavily on nuclear power), Seoul agreed...
...Life photographer for three decades; in Norwalk, Connecticut. A native of New Zealand, he joined Life during World War II; he was with American forces in the Battle of the Bulge and was the first to photograph the city of Nagasaki, Japan, when it was hit by an atom bomb. After the war, he adapted a photo-finish camera meant for horseracing into an instrument for capturing athletes in motion. In 1972, he was in Nepal on assignment when he got the news that Life had folded; he responded with ?Your message ... badly garbled. Please send one-half million dollars...
Bohr's life (1885 - 1962) is roughly divided into two halves: the years of his seminal contributions to atomic science, and his later role as scientific statesman during and after WW II. Ottaviani and Purvis take care to explain the concepts behind Bohr's multiple scientific breakthroughs, making the book a kind of illustrated primer on atomic physics. It was Bohr, for example, who proposed a model of the atom as a kind of mini solar system, with electrons orbiting around a nucleus. But this had its limits, both experimentally and "philosophically." So he moved to introduce Quantum Mechanics...
...journal Radiology precisely how much radiation you are exposed to in a single full-body scan. It turns out to be 100 times the radiation dose of a typical mammogram--or roughly equivalent to that received by Hiroshima survivors 1.5 miles away from the center of the atom bomb blast. According to David Brenner, lead author of the study, the risks associated with just one scan are relatively modest, likely to increase your chances of dying from a radiation-caused cancer to about 0.08%. But if you were to get scanned every year for 30 years, your risk of developing...
...HIDDEN THE MYSTERIES OF HEREDITY, OF GROWTH, OF DISEASE AND AGING ... As the basic ingredient of the genes in the cells of all living organisms, DNA is truly the master molecule of life. [The discovery] was one of the great events in science, comparable to the splitting of the atom or the publication of Darwin's Origin of Species...
