Quantum Physics, Mini Black Holes and the Multiverse by Yasunori Nomura; Bill Poirier; John Terning; Farzad Nekoogar (Editor) Modern physics is rife with provocative and fascinating ideas, from quantum mechanics to the multiverse. But as interesting as these concepts are, they are also easy to understand. This book, written with deft hands by true experts in the field, helps to illuminate some of the most important and game-changing ideas in physics today." (Sean M. Carroll) "The Multiversal book series is equally unique, providing book-length extensions of the lectures with enough additional depth for those who truly want to explore these fields, while also providing the kind of clarity that is appropriate for interested lay people to grasp the general principles involved." (Lawrence M. Krauss) This book explores, explains and debunks some common misconceptions about quantum physics, particle physics, space-time, and Multiverse cosmology. It seeks to separate science from pseudoscience. The material is presented in layperson-friendly language, followed by additional technical sections which explain basic equations and principles. This feature is very attractive to non-expert readers who nevertheless seek a deeper understanding of the theories, and wish to explore beyond just the basic description.

Nature Portfolio: latest Theoretical physics articles Latest research and reviews. Theoretical physics is the development of mathematical formalisms and computational protocols for describing all aspects of objects found in the world around us and their interaction. This can involve both providing models for understanding empirical results or constructing self-logical theories for explain phenomena beyond current experiments.

Manhattan Project research starter Otto Hahn and Lise Meitner discovered uranium fission during the late 1930’s. The immense amount of energy released in the process opened up the possibility that uranium could be used as an explosive of unprecedented destructive power. In a letter delivered to President Franklin D. Roosevelt on October 11, 1939, physicists Albert Einstein and Leo Szilard alerted the president that Nazi Germany might be researching nuclear fission to develop a nuclear weapon and that the United States should follow suit. At Roosevelt’s direction, an aide set up an Advisory Committee on Uranium to keep the president informed as research continued. In June of 1942, the committee reported that the research had advanced to the point that construction of a pilot plant and preliminary design of production plants for fissionable material were possible. It recommended that the U.S. Army Corps of Engineers begin construction. President Roosevelt agreed. An unnamed engineering district under the direction of Colonel James C. Marshall was created on June 18, 1942, to carry out this responsibility.

Disarmament Research Starter Cold War-era attempts by the superpowers to bring about the reduction or abolition of troops and weaponry. With the devastation caused by both conventional and atomic weapons during World War II, hopes were high that the newly created United Nations (U.N.) would foster international peace and security by promoting disarmament. In a 1950 address to the U.N. General Assembly, President Harry S. Truman initiated a new American policy on arms control that coupled conventional and nuclear weaponry, but the outbreak of the Korean War brought negotiations to an impasse. Early in 1952, the United Nations set up a disarmament commission, and in April, the United States proposed that, before any arms reductions, an international inspection system be established. However, the Soviet Union insisted on a cut in conventional arms and an atomic weapons ban before the creation of an inspection system. In the climate of the Cold War, the Soviets interpreted inspections as a subterfuge for intelligence gathering.
