The early stories and the first book in the series were published in the wake of the impact of Sputnik 1 and the Space Race and reflect the thinking of that period. The first book even includes a plug for joining the United States Air Force in the last story, "Night Rescue". There are two odd, inexplicable exceptions to the usually science ...
A model of an atomic nucleus showing it as a compact bundle of protons (red) and neutrons (blue), the two types of nucleons.In this diagram, protons and neutrons look like little balls stuck together, but an actual nucleus (as understood by modern nuclear physics) cannot be explained like this, but only by using quantum mechanics.
Bookclub is a monthly programme, devised by Olivia Seligman and hosted by Jim Naughtie and broadcast on BBC Radio 4.Each month a novel is selected, and its author invited to discuss it.
Furthermore, the energy needed to excite the nucleus (i.e. moving a nucleon to a higher, previously unoccupied level) is exceptionally high in such nuclei. Whenever this unoccupied level is the next after a full shell, the only way to excite the nucleus is to raise one nucleon across the gap, thus spending a large amount of energy. Otherwise ...
The incoming gamma ray effectively knocks one or more neutrons, protons, or an alpha particle out of the nucleus. [1] The reactions are called (γ,n), (γ,p), and (γ,α), respectively. Photodisintegration is endothermic (energy absorbing) for atomic nuclei lighter than iron and sometimes exothermic (energy releasing) for atomic nuclei heavier ...
All the nuclear reactions that had been documented involved chipping protons or alpha particles from the nucleus. Breaking it up seemed far more difficult. However the liquid drop model that Gamow had postulated suggested the possibility that an atomic nucleus could become elongated and overcome the surface tension that held it together. [102]
Bokklubben World Library (Norwegian: Verdensbiblioteket) is a series of classical books, mostly novels, published by the Norwegian Book Clubs [] since 2002. It is based on a list of the hundred best books, as proposed by one hundred writers from fifty-four countries, compiled and organized in 2002 by the Book Club. [1]
The Pulpwood Queens is a meet-and-greet book club founded in early 2000 in Jefferson, Texas, by Kathy L. Patrick in a combined beauty salon and bookstore, Beauty and the Book. In a joint effort with Random House, the club spawned an Internet book club show that began in January 2011, Beauty and the Book: Where Reading is Always in Style. [1]
