What is quantum mechanics based on?
Quantum Mechanics is a discipline of higher level mathematics and physics. The most basic description of Quantum Physics is the study of the building blocks of the universe, and the forces that govern those particles.
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.
What happens in the quantum cafe?
The quantum cafe is used by Brain Greene in his book The Elegant Universe to illustrate the weirdness of quantum mechanics. It is also featured in the NOVA documentary with the same name based on his book. A lot of things happen in the cafe, people and objects change in shape, objects teleport around, you order one drink but you get another. As Brain himself remarks you are never sure what you will get when you order something. Since this is just an illustration it is not meant to be a literal description of quantum mechanics. Most of the things in the quantum cafe can be related to the Uncertainty Principle of quantum mechanics.
Is there any type of math harder then quantum mechanics?
This is a tough question to answer because how "hard" something is is relative.A clearer question to ask would be, "In physics, does quantum mechanics contain the "hardest" math when compared to the other major areas of physics (i.e. mechanics, E&M, thermodynamics)?" To answer the new question: From my experience, in undergraduate physics, yes. Quantum mechanics is not necessarily the most mathematically intense but it uses many many mathematical tools to solve various problems.
Why you use some classical mechanics in quantum mechanics?
That has been a topic of much debate since th1900's. There has been no fully successful tying of the two branches of physics yet but, many proposed theories have made great leaps forward to the answer. For example quantum gravity theory and the string theory, the latter being the more current and relevant.There are two areas in which the transition from quantum mechanics to classical mechanics is rather obvious: Statistical thermodynamics and wave-particle duality.Answer2:Classical and Quantum Mechanics merge in Quaternion Mechanics.Quaternion Mechanics consists of Quaternion quantities like energyW = -vh/r + cP where -vh/r is the scalar enrgy and cP=cmV is the vector energy.Classical and Quantum Mechanics need Quaternion quantities. In general the potential energy -vh/r is a scalar aka a Boson and vector energy cP is a vector aka a Fermion. Bosons/Scalars have integer spin and Fermions/Vectors have 1/2 integer spin.For the most part like Newtonian Physics use only scalars -mGM/r a scalar and no vectors. Likewise, Quantum mechanics use mostly Fermions or Vectors and few scalars. The speed of light is a scalar as is Planck's Constant h.Quaternion Mechanics merges Classical and Quantum Physics.The Laws of Quaternion Mechanics are:0 = XB = [d/dr, DEL] [B,B] = [dB/dr -DEL.B, dB/dr + DEL B ]0 = X2B = [(d2/dr2 - DEL2), 2d/dr DEL] [-vh/r,cP]This Quaternion Wave gives thescalar/Boson wave -(d2/dr2 - DEL2)vh/r - 2d/dr DEL.cP =0and thevector/Fermion particle (d2/dr2 - DEL2)cP + 2d/dr DEL -vh/r =0In Nature, Quaternions rule and Quaternions combine Bosons and Fermions.A Quaternion can be a Boson or a Fermion or Both as inX2W =[ -(d2/dr2 - DEL2)vh/r - 2d/dr DEL.cP,(d2/dr2 - DEL2)cP + 2d/dr( DEL -vh/r + DELxcP) ]Quaternions consist of Scalars and Vectors , Bosons and Fermions.
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.

Is quantum mechanics same as quantum physics?
It most certainly is! It has to do with things that are very small. Atomic [or Nuclear] Physics is essentially the study of the quantum world.
Quantum mechanics is considered successful because most experiments designed to test quantum mechanics support the theory?
yes. 100%. look up the atomic spectra of helium for a good example.
Who was Schrodinger and what did he call his cat?
He was a physicist that is most known for working with quantum mechanics. Schrodinger's cat was his thought on the uncertaintiness of the modern model of quantum mechanics. The cat was either dead or alive but also neither.

What is quantum technology?
Quantum applied science is a young discipline of physics and technology, which transitions, some of the stranger characteristics of quantum mechanics, especially quantum entanglement and most recently quantum tunneling, into virtual applications such as quantum computing, quantum coding, quantum simulation, quantum metrology, quantum sensing, and quantum imaging.
What are most of Albert Einstein's discoveries?
Albert Einstein is most known for his theory of relativity, specifically the theory of special relativity and the theory of general relativity. These groundbreaking theories revolutionized our understanding of space, time, and gravity. Einstein also made important contributions to quantum mechanics and the photoelectric effect, which later led to the development of quantum theory.
How many theories did Einstien have?
Albert Einstein is known for his contributions to theoretical physics, most notably the theory of relativity which encompasses both the special theory of relativity and the general theory of relativity. While he proposed other theories and made significant contributions to quantum mechanics, it is the theory of relativity that he is most famous for.
Quantum theory suggests that the world is?
Perhaps the most noted implication of Quantum theory is that it suggests the world is not deterministic. Specifically, if we have all the knowledge that it is possible to have about the world (or any part of the world) we are still not able to exactly predict the future. This is a law of nature and not a consequence of the inaccuracy of our ability to measure things. Quantum theory gives us the ability to predict the future in probabilistic fashion. We can assign probabilities to all futures or all outcomes of measurements in the future, but we can not say specifically which result will occur. Theories prior to 1900 were exact in their predictions, e.g. mechanics and electromagnetic theory and thermodynamics. But, these theories did not look closely enough at the microscopic world and were found in need of improvement (correction) with the advent of quantum mechanics.

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.
