radiation does not act continuously‚ into his mathematics in essence Planck had discovered the quantum structure of electromagnetic radiation. In 1905 Einstein attempted to resolve the conflict between wave and particle theories by demonstrating that part of Planck’s formula can arise only if electromagnetic radiation behaves as if it actually consists of individual "quanta" of energy. With his light quantum hypothesis Einstein could derive both Planck’s formula and also account directly for certain

to the resistivity of a metal or semiconductor. The effect is quantum-mechanical in nature and has the following origin: In a disordered electronic system‚ the electron motion is diffusive rather than ballistic. That is‚ an electron does not move along a straight line‚ but experiences a series of random scatterings off impurities which

Where Science and Buddhism Meet Within the world that we live today exist many religions‚ beliefs‚ cults‚ or forms of spirituality‚ which move us in a certain way and influence the lives around us and how we interact. For century’s religion have been moving people and persuading people to do certain things‚ which have been believed to support the word of God and respect his decisions. But as time has evolved people have become less believing of certain things because of the rise of technology. Back

Quantum mechanics can also explain the Electromagnetic force. So on the one hand we have quantum mechanics that explains three of the four fundamental forces and on the other the theory of relativity that explains gravity. Einstein worked the rest of his life on a theory that unified the four forces

H2O vs H2O2) * Law of conservation of mass: atoms cannot be created or destroyed during a chemical reaction

I am going to discuss the modern concept of the atom. I am going to give a brief history of the atomic model including Thomson’s atom‚ Rutherford’s atom‚ Bohr’s atom‚ and Schrödinger’s atom. I am going to include a diagram for each of these models. In 1897 physicist‚ J.J. Thomson‚ shortly after discovering electrons‚ proposed his Plum-Pudding model of the atom. He based this model on the two facts that he knew at the time: 1. atoms contain small negatively charged particles called electrons

asudhaiva Kutumbakam is a philosophy that inculcates an understanding that the whole world is one family. It is a philosophy that tries to foster an understanding that the whole of humanity is one family. It is a social philosophy emanating from a spiritual understanding that the whole of humanity is made of one life energy. If the Parmatma is one how then an Atma can be different? If Atma is different how then can it ultimately be dissolved in the Parmatma? If the whole ocean is one how then a drop
