Physics of Societal Issues: Calculations on National by David Hafemeister

By David Hafemeister

This publication presents the reader with crucial instruments had to study advanced societal matters and demonstrates the transition from physics to modern day legislation and treaties. This moment version beneficial properties new equation-oriented fabric and large info units drawing upon present details from specialists of their fields. difficulties to problem the reader and expand dialogue are provided on 3 well timed issues:


•        nationwide defense: guns, Offense, protection, Verification, Nuclear Proliferation, Terrorism

•        atmosphere: Air/Water, Nuclear, weather switch, EM Fields/Epidemiology

•        strength: present strength state of affairs, constructions, sun structures, Renewable  Energy, stronger End-Use potency, Transportation, Economics


Praise for the 1st edition:

"This perception is required in Congress and the administrative department. Hafemeister, a former Congressional fellow with extensive Washington adventure, has written a publication for physicists, chemists and engineers who are looking to research technological know-how and coverage on guns, power, and the surroundings. Scientists who have the desire to make a distinction will wish this book."

Richard Scribner, first Director, Congressional technological know-how and

Engineering Fellow software, AAAS


"Hafemeister exhibits how a lot you'll be able to comprehend approximately nuclear guns and missile matters via easy back-of-the-envelope calculations. He additionally offers compact motives of the in part profitable makes an attempt which were revamped the previous 60 years to regulate those guns of mass destruction. expectantly, Physics of Societal matters may help curiosity a brand new iteration of physicists in carrying on with this work."

Frank von Hippel, Professor, Princeton, former Assistant Director,

National defense, White condo, OSTP


"Energy coverage has to be quantitative. those that do not calculate fiscal tradeoffs usually champion simplistic undefined. ‘The resolution is more... nuclear strength, or electrical autos, or photovoltaics, etc.’ a few uncomplicated physics will exhibit that the real answer fits provide and insist as an ‘integrated source plan.’ Physics of Societal concerns is an efficient starting point this journey."

Arthur Rosenfeld, former California strength Commissioner,

Professor-emeritus, U. of California-Berkeley

Climate Change Policy in the European Union

The ecu Union (EU) has emerged as a number one governing physique within the overseas fight to manipulate weather switch. The transformation that has happened in its regulations and associations has profoundly affected weather swap politics on the overseas point and inside its 27 Member States. yet how has this been accomplished while the ecu contains such a lot of degrees of governance, whilst political management in Europe is so dispersed and the coverage offerings are particularly tricky?

International Energy and Poverty: The emerging contours (Routledge Studies in Energy Policy)

Round 2. eight billion humans globally, sometimes called the "Other 3rd" or "energy poor", have very little entry to invaluable strength that meets their wishes for cooking, heating, water, sanitation, illumination, transportation, or simple mechanical strength. This e-book uniquely integrates the hitherto segmented and fragmented ways to the problem of entry to power.

Climate Change and Displacement: Multidisciplinary Perspectives

This booklet - now to be had in paperback - brings jointly numerous disciplinary views at the phenomenon of climate-induced displacement. It deals a rigorous holistic research of the phenomenon, with the intention to larger tell educational realizing and coverage improvement alike. every one bankruptcy identifies key matters that have to be thought of in shaping household, local, and foreign responses, together with the complicated motives of circulation, the conceptualization of migration responses to weather switch, the terminology that are meant to be used to explain those that flow, and attitudes to migration which can impact judgements to stick or go away.

But RNEP would be delivered as a bomb, guided with a laser to be more accurate, but not as penetration as if from a missile. RNEP was intended to attack underground chem/bio stockpiles, but it would have to be close to the stockpiles for combustion. RNEP was finally terminated in 2006. (See reference by Nelson). Reliable Replacement Warhead. The Comprehensive Nuclear–Test–Ban Treaty bans nuclear warhead tests. Using more cautious designs, warheads can be built that are more robust, further from the reliability margins, and without the use of Be and BeO as neutron reflectors.

The spontaneous neutron rate is four times larger in reactor-grade plutonium (24 % 240Pu), which itself would be doubled if it were in plutonium oxide form from the (α, n)-reaction. Clearly it is more difficult to make a warhead with reactor-grade plutonium, but it can be done. 5. 3 ms) during near criticality, considerably lowering the yield. The assembly time of an implosion bomb is reduced by a factor of 100 compared to the gun-barrel design; this is due to two things: The critical implosion sizes are less than 10 % the length of the gun barrel and the implosion velocity is a factor of 10 higher than the projectile velocity of a little boy gun-type weapon.

5 is lost to space and 1 is available to double the fission rate. The number of neutrons rises according to N ¼ 2i for i neutron generations. The number of doublings to fission 2  1024 of 235U is À Á i ¼ lnN=ln2 ¼ ln 2  1024 =ln2 ¼ 81 À 1 ¼ 80: ð1:27Þ One generation was subtracted because the number of neutrons in the last generation equals the sum of all previous generations. 4  1024. 8). Following Serber and Mark, the neutron production rate from the diffusion equation is dn=dt ¼ ÀD∇2 n þ ½ðη À 1Þ=τŠn, ð1:28Þ where n is density of neutrons, η is neutron multiplicity, and D is the diffusion coefficient.
