Best Answer

Quantum mechanics and relativity are both parts of the same puzzle: how the universe works. They are both equally important, because they both explain things that are not explained by classical physics.

When and where do newton's laws of motion and quantum mechanics overlaping?

This is the question that physicists all around the world are trying to answer. When they come up with one I'll be sure to get back to you. This area is primarily the work of string theorists.AnswerI think the previous answerer misread the question. If the question had been "When and where do general relativity and quantum mechanics overlap?" then this answer would have been fine. But there is no conflict between Newton's Laws and quantum mechanics. More precisely: If you take quantum mechanics and let Planck's constant tend to 0, you get Newtonian physics. (Or special relativity - but if you then let the speed of light tend to infinity you get Newtonian physics.) In other words, classical physics is a special case of quantum physics. If you avoid doing experiments with very small or very fast things, Newton's laws will hold.


What is the Difference between relativity and quantum mechanics?

Quantum Mechanics is the study of the intimate behavior of the smallest forms of particles, and their interaction amongst, with special emphasys on the emissions of energy, which is delivered in quanta, or photons. Wave Mechanics is the study of many physical phenomena that happen in a non linear and recurrent behavior, usually addressed as wave, with special emphasys in both the features of said wave, and the energy that involves specific wave phenomena.


What is quantum mechanics?

Quantum mechanics is the mathematical description of matter on an atomic and subatomic scale. It is focused around the wavefunction of a system. Wave functions contain all information about the system such as: momentum, position, angular momentum, energy, etc. This information can only be known by its respective probability distributions. The basis of quantum mechanics in the wave mechanics formulation is the Schrodinger equation, which has two forms: the time-dependent and the time-independent.Quantum mechanics is a branch of mechanics concerned with mathematical modelling of the interaction and motion of subatomic particles.


What are important properties of quantum mechanics?

Important properties of quantum mechanics include wave-particle duality, superposition, and entanglement. Wave-particle duality suggests that particles can exhibit both wave-like and particle-like behavior. Superposition refers to the ability of quantum systems to exist in multiple states simultaneously. Entanglement describes the phenomenon where the states of two or more particles become correlated and cannot be described independently.


What is classical particle?

Classical physics refers to the branch of Physics whereby energy and matter are two very different concepts. It is usually based on the theory of electromagnetic radiation and the laws of motion.

Suggest you best book on quantum mechanics?

In Search of Schrodinger's Cat is a good one, although it focuses a little more on quantum physics than mechanics.

What explains particle motion?

There are many kinds of particles and many kinds of motion, so there is more than one answer to that question. In many cases, particle motion is explained by Newtonian mechanics. In other cases, you would need quantum mechanics or Einstein's theory of relativity, or the Maxwell equations if the particles are photons.


What is loop quantum gravity?

It is an attempt to merge quantum mechanics and the General Theory of Relativity.For more details, I suggest you read at least the overview in the Wikipedia, article "Loop quantum gravity".


Can somebody help a student find a good college to study quantum mechanics or become a quantum physicist?

Two of the very best schools for what you want (there are many, many more) are M. I. T. and Standford.The best place for Quantum Mechanics would be the Max Plank institute in Germany.

Who are the ten most famous physicist?

This list is not intended to be fact. The following are arguably some of the more famous physicists of modern times:Albert Einstein (Special and General Relativity)Richard Feynman (Quantum Electrodynamics)James Clerk Maxwell (Electromagnetism)Ludwig Boltzmann (Thermodynamics)Erwin Schrödinger (Quantum Mechanics)Werner Heisenberg (Quantum Mechanics)Isaac Newton (Classical Mechanics / Gravitation)Edwin Hubble (Cosmology)Stephen Hawking (Cosmology)Max Planck (Quantum Mechanics)I would include Galileo Galilei and Benjamin Franklin, but their fame is mostly derived from their contributions to astronomy and politics, respectively. Other famous people who have made contributions to physics include Thomas Edison, Avicenna (Ibn Sina), Stephen Wolfram, Wernher von Braun, Archimedes, Carl Gauss etc.


What is the two division of physics?

In study:Classic physics - The study of motion, forces, electricity and heat. This is sometimes called Newtonian physics.Modern physics - The study of quantum mechanics, relativity (general and special) subatomic particles and astrological forces/events.

Who is Schrodinger and Heisenberg?

Schrödinger and Heisenberg are known to be two of the important founders of quantum mechanics. They both invented a mathematical formalism for quantum mechanics. Schrodinger's formalism which was based on the wave equation was the most popular one. Heisenberg's formalism was based on the notion of quantum jumps (the innate "randomness" of sub-atomic physics the very reason that the famous "Schrodinger's cat" is not alive or dead...). Heisenberg's formalism was innovative but more difficult to handle. The difference on the formalism reflects their different views on the interpretation of quantum mechanics; Schrondinger was more a realist and he was sharing Einstein view that randomness is not desirable in the description of sub-atomic physics. Heisenberg on the other hand was more a supporter of the Copenhagen Interpretation of quantum mechanics which interprets the sub-atomic randomness as an innate characteristic of the sub-atomic world and the very heart of quantum physics theory.
