New basics of the physics of the universe, to supersede Bohr-Einstein theories, propose that the universe undergoes infinite cycles of Big Bang explosion, expansion, contraction and new explosion. Practical consequences include the creation of extremely high stable temperatures, and the possibility of ...
Physics - Accelerator PhysicsRF electronics deals with the generation, acquisition and manipulation of high-frequency signals. In particle accelerators signals of this kind are abundant, especially in the RF and beam diagnostics systems. In modern machines the complexity of the electronics assemblies ...

Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which completely depends on their mining source. They ar
Alpha particles have two protons and two neutrons, so in this process atomic number of parent nucleus is changed by 2 and mass number is changed by 2. Some energy is also emitted in this process. Uranium, plutonium americium etc are alpha particle emitters. 2. Beta decay:-. Elements which...
