Einstein's work on the Photoelectric effect, which won him the Nobel prize in 1921 was a bulwark of Quantum Mechanics. Einstein went off in another direction because of his inate suspicion that Quantum Mechanics has severe internal difficulties. Quantum Mechanics and Relativity have not yet been reconciled--but they are moving together slowly. Quantum Gravity seems to be key to the issue and may be resolved by String Theory.

∙ 13y agoThat depends on what you're trying to measure. If the object is large and massive, then relativity holds true. If it's very small, like atoms, then quantum mechanics is true. One problem is that relativity and quantum mechanics cannot be both true at the same time. Theoretical physicists are trying to find a way to "unify" relativity and quantum mechanics so they can measure things that are both small and massive, like black holes.
There is a very interesting subject called quantum field theory - though there is active research, it is amazing how much we already know about relativistic QM.

Is Quantum Mechanics more important than Relativity?
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.
Who had two theories of relativity and was big in quantum mechanics?
Albert Einstein developed the theories of general relativity and special relativity. He also did work in quantum theory. (He won a Nobel prize for his work with light.)
Did Einstein study quantum mechanics?
actually einstein developed one of the earliest parts of quantum mechanics: the theory of the photoelectric effect. he worked directly with many of the scientists that later developed the complete theory of quantum mechanics and the mathematics to solve its apparent paradoxes to get usable predictions from the theory. later he rejected it due to it being nondeterministic, not because he didn't understand quantum mechanics but because he did understand quantum mechanics. he then tried to combine quantum mechanics and general relativity, hoping the resulting unified field theory would resolve the nondeterminism of quantum mechanics, resulting in a single fully deterministic theory of everything.
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 a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
Why it is said relativistic quantum mechanics?
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler. Physics students typically study regular quantum mechanics before moving on to quantum field theory.
What are the discoveries of Einstein?
Special Relativity, General Relativity and the beginnings of Quantum Mechanics.
What is QM it seems to be in relation to the Relativity Theory?
Quantum Mechanics
What were Einsteins contributions?
The related link Wikipedia article lists some. Probably his most famous are his theories of Special Relativity and General Relativity. He laid the groundwork for quantum mechanics and other modern physics concepts.Special Relativity, General Relativity and the beginnings of Quantum Mechanics.
Why are Newton's laws not exact?
Because they do not iclude quantum mechanics and general relativity

What were Albert Einsteins accomplishments?
the theory of relativity & quantum mechanics.
Which thing correlates general relativity with quantum mechanics?
nothing, they appear to contradict each other.
What are th 6 divisions of physics?
There are six divisions of physics. There are classical mechanics, thermodynamics and statistical mechanics, electromagnetism, relativity, quantum mechanics, and interdisciplinary fields.
Who created Quantum Mechanics and is it true that it is replacing the old physics?
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
Does the string theory bridge the gap between Einstein's theory of relativity and quantum mechanics?
No, string theory is an attempt to bridge the gap between EVERYTHING, not just relativity and quantum, into one fundamental theory.
