Physics of Societal Issues: Calculations on National Security, Environment, and EnergySpringer Science & Business Media, 10/08/2007 - 487 páginas Physics of Societal Issues is a textbook for all those who wish to discuss the fundamental issues of energy use, nuclear weapons, and the environment using facts and figures instead of slogans and postures. It will provide the reader with the tools and insights needed to analyze many complex issues with insights gained from informed estimates and simple calculations. Taking his inspiration from Fermi's famous "back of the envelope" calculations, Hafemeister shows how to capture the essence of a problem in rough estimates of the important parameters and then to use those estimates to gauge the effects of policy decisions. Hafemeister draws on dozens of years of experience working on just these issues in the US Senate, the national Academy of Sciences, and several Federal agencies, as well as the Lawrence-Berkeley, Los Alamos, and Argonne national laboratories to provide details and examples as well as insight into the issues needed to plan public policy. The book is divided into three parts, each treating an area in which physics plays a major role: - National security: nuclear weapons and their effects, missile defenses, arms control and verification, and nuclear proliferation and terrorism - The environment: pollution dispersal and control, radioactive pollution, climate change, and the epidemiology of electromagnetic radiation - Energy: estimating energy resources and use, use of energy in buildings and for transportation, renewable energy sources, and the economics of energy use. Each chapter includes numerous problems to challenge the reader and to extend the discussion. It is the only equation-oriented book for physics seniors and gradutate students that covers the three main physics and society issues. |

... absorbed one neutron, such an element, if assembled in sufficiently large mass, could sustain a nuclear chain reaction. I didn't see at the moment just how one would go about finding such an element. . . . Szilard thought that neutron ...
... absorbed neutron includes pairing energy from combining spin-up and spin-down neutrons. On the other hand, 238U with an even number of neutrons has a smaller neutron binding energy of 4.8 MeV since the pairing energy is not available ...
... absorption, and edge effects, the rate of change in n is proportional to n, giving exponential growth, dn/dt = [(k − 1)/τ]n, (1.29) with a solution n = no e(k−1)t/τ. The effective number of neutrons emitted per captured neutron is k ...
... absorption of neutrons by 6Li in thermal reactors. DOE stated in 1998 that it would begin tritium production of 2.5 kg/yr by 2005 for nuclear weapons under START I, which could sustain some 6000 warheads. DOE stated it would postpone ...
