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.
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.
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.
Bohr's model of the atom was a precursor to quantum mechanics, providing a framework for understanding the discrete energy levels of electrons. It introduced the idea of quantized energy states and laid the foundation for the development of quantum theory. Quantum mechanics later expanded on Bohr's model, offering a more comprehensive explanation of the behavior of particles at the atomic and subatomic levels.
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.
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.
Classical mechanics is important because it provides the foundation for understanding the motion of objects and the underlying principles that govern their behavior. It allows us to predict how objects will move under various conditions, which is crucial for fields such as engineering and physics. Classical mechanics also forms the basis for more advanced branches of physics, such as quantum mechanics and relativity.
Modern physics refers to the branch of physics developed in the 20th century, focusing on theories and discoveries that have revolutionized our understanding of the universe. It includes quantum mechanics, relativity, particle physics, and cosmology, among other advanced topics.

Einstein's theory of relativity describes the physics of large objects in the universe, while quantum physics explains the behavior of particles at the smallest scales. They clash because they have different conceptual frameworks and mathematical descriptions of the universe. Einstein struggled to accept the probabilistic nature of quantum mechanics and believed there might be a more complete underlying theory that unified both areas of physics.
In Search of Schrodinger's Cat is a good one, although it focuses a little more on quantum physics than mechanics.
The rotating wave approximation is important in quantum mechanics because it simplifies the mathematical calculations involved in describing the interactions between particles and electromagnetic fields. By neglecting certain terms in the equations, the approximation allows for a more manageable and accurate analysis of quantum systems.

Quantum mechanics is important for understanding subatomic particles because it provides a framework to describe their behavior at a very small scale. It helps explain phenomena such as particle-wave duality and uncertainty, which classical physics cannot fully account for. By using quantum mechanics, scientists can make more accurate predictions about the behavior of subatomic particles.
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.
On the physics forum, you can find discussions on various topics related to physics, such as quantum mechanics, relativity, thermodynamics, and more. Users often engage in conversations about theories, experiments, and current research in the field of physics.
The Husimi function in quantum mechanics is significant because it provides a way to visualize the quantum state of a system in phase space, which helps in understanding the behavior of quantum systems. It offers a more intuitive and classical-like representation of quantum states, making it easier to analyze and interpret complex quantum phenomena.
