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 energy
W = -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 the
scalar/Boson wave -(d2/dr2 - DEL2)vh/r - 2d/dr DEL.cP =0
and the
vector/Fermion particle (d2/dr2 - DEL2)cP + 2d/dr DEL -vh/r =0
In Nature, Quaternions rule and Quaternions combine Bosons and Fermions.
A Quaternion can be a Boson or a Fermion or Both as in
X2W =[ -(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.
Not sure what you mean by "connected," but a basic principle of quantum mechanics is that its laws must merge with those of classical mechanics if the particle being observed over a certain distance has a momentum significantly larger than the Planck's Constant divided by that distance.
When the system gets big. This is called the correspondence principle.
Classical mechanics is not used in quantum mechanics.
no
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.
The obvious choice would be a research or academic physicist. These are professions that are primarily in the public sector meaning that you would be employed by a university or the government. As for industry, there are still some companies that employ quantum physicists but they are usually R and D departments of large technology companies. Not a lot of businesses directly employ quantum mechanics directly, but there are a lot that use the results of experiments to develop new, and improve old, technologies. Possible areas for research include superconductivity, quantum computing, particle physics and string theory. Maybe chemistry too.
Answer:It is not clear . Some books advocates Max plank, some Neils Bohr , some Erwin Schrodinger and some even say Heisenberg . Definitely Max Planck. No Doubt !Answer:Max Planck was the first to use ideas of quantum theory when he solved the "ultraviolet catastrophe" in December of 1900. At the time, however, neither he nor the vast majority of the scientific community noticed the implications of his "quantization of energy."In 1905, Albert Einstein published a paper on the photoelectric effect in which he described energy transfer via light in the form of photons. He was one of the first physicists to acknowledge that particles could only obtain certain discrete energies.Many textbooks, however, will credit Max Planck as the "father of quantum theory."
Quantum mechanics has greatly developed our understanding of physics, chemostry and the universe as a whole. For one, it has enabled scientists to uncover and explain the structre of atoms and other sub-atomic particles. Also, it gives answers to some of the problems which cannot be solved using classical physics - the Ultraviolet Catastrophe was one aspect where classical physics failed. Wolfgang Pauli discovered the phenomenon of electron spin, Niels Bohr the structure of the orbits, and Max Planck solved the mystery of the Black Body Radiation (and the Ultraviolet Catastrophe, by quantizing energy into E=hf). Other famous quantum physicists include: Dirac, Einstein, Heisenberg, Boltzmann, Schroedinger... Also, scientists are currently looking into constructing and designing a functional 'quantum computer' - which would be immensely powerful.
The main branches of classical physics include: Classical Mechanics Electromagnetism Classical Optics Thermodynamics Fluid mechanics In modern physics, there are a lot of different fields of study including: The Special Theory of Relativity The General Theory of Relativity Quantum Mechanics. Nuclear Particle Physics Solid state physics, incuding semiconductors. Statistical thermodynamics Quantum Electrodynamics (QED) Quantum Chromodynamics (QCD) In Modern Physics, optics and electricity & magnetism have been unified, especially through the use of Special Relativity. [Three of the most important fields of Modern Physics had been left out. I have put them first , second, and third on the list. By definition, these are Modern Physics because they are products of the 20th century. Also, some very important parts of Classical Physics had been left out, such as fluid mechanics.]
Yes, but the macroscope reacts to the substance and it can explode
no
electrical engineers and quantum mechanics use them.
using contraction and expansion
No, it is not necessary.

Schneider's cat works by quantum theory of superposition, and interpretations of quantum mechanics have been proposed. There for showing you the use of Schneider's cat work.
Experiments in the early 20th century could not be explained by classical physics (developed by Galileo, Newton, etc.). Classical physics worked fine on a larger scale. However, on an extremly small scale it was flawed. Scientist started looking at things on an atomic level. This was the beginning of Quantum mechanics. This science was greatly advanced during WWII, when the military use was realized. Hope this helps some
Classical Physics is the physics which was taught and used before RELATIVITY and QUANTUM MECHANICS were introduced. In Classical physics, masses remain constant when they accelerate and clocks tick in unison wherever they are and at all velocities. But this is not true, especially at very high speeds. Relativity is more accurate and is necessary for the speeds that satellites travel at. Classical mechanics cannot explain the dynamics of sub-atomic particles or how light and other kinds of radiation interact with matter. It is necessary, in explaining the structure of atoms and the nuclear processes, to use Quantum Mechanics which "quantises" energy. For example, if one particle is to pass energy to another particle, it can only be done if an exact amount of energy is available. This amount is a "quantum" and the size of a quantum depends on the wavelength of the radiated energy. Nobody knows why. We understand the laws of Classical Physics - they seem logical. Nobody understands relativity or quantum mechanics. However, the laws are true and so we use them and get the right answers. Why the laws of Modern Physics are with us is beyond our understanding, simply because we are humble three dimensional beings, limited to passage through time in a direction and rate beyond our control. In Modern physics there can be many more dimensions and time may pass at variable rates in different places. That is why we can't understand Modern Physics.
Some of the jobs that use complex conjugates include quantum mechanics, electrical engineers and physicists. Complete understanding of generators and motors require the knowledge of imaginary numbers.
Quantum Computers are a new type of computer that uses the principles of quantum mechanics to perform operations. Unlike traditional computers, which use bits to store and process information, Quantum Computers use qubits. Qubits can represent 0 and 1 at the same time, allowing Quantum Computers to perform multiple operations simultaneously.
