String theory is one of the leading candidates for a theory of everything, that is, a theory that unifies all 4 basic forces of nature, viz, gravity, the electromagnetic force, the strong force and the weak force. The last 3 forces mentioned above are described by quantum mechanics. This is the link between quantum mechanics and string theory.
ps- If you believe in watertight definitions, then quantum mechanics is all the quantum theory till Dirac's equation. I'm taking quantum mechanics as the theory of the small as such, that is, all of the phenomena of the small from Plank till the standard model and beyond.
Firstly, there definitely are plates, and they definitely move. Those are facts. Secondly, "theory" in science doesn't mean the same thing it does in everyday language. In science, something doesn't qualify as a theory unless it explains everything we already knew and (correctly) predicts things we didn't already know. A "theory" is something that is generally considered to be almost certainly true, barring later discoveries showing that it may not be complete. That doesn't make it "wrong", necessarily, it just means it may only apply in special cases (or, perhaps, may NOT apply in certain special cases).
1. Determine which sort of spiral you wish to draw.- Clockwise or Anticlockwise. 2. Wind a long string around a pillar box /telegraph pole / lampost /etc in the appropriate sense 3. Tie your pencil to the end. 4. Apply paper underfoot. 5. Press pencil to paper and walk away allowing string to unwind while keeping it taut. 6. Repeat using longer string and wider/ narrower post as required.

Apply For the Show
In fact, the laws of motion do apply; you just have to be careful which set of laws you use. Newtonian laws of motion do not apply to light or to the movement of atoms, but relativity theory applies to light, and quantum mechanics applies to movements at the atomic and sub-atomic levels.
Answer: The Heisenberg uncertainty principle is a fundamental part of quantum mechanics so chance is prerequisite to everything.
Quantum Mechanics and Quantum Physics apply to so many aspects of science that, despite how radical it is, its still accepted. This is because almost all of astronomical physics and other areas of science would just collapse! For example, black holes appear to radiate energy, but a black hole (by definition) does not give out anything. Therefore, Quantum Mechanics says that there are certain fluctuations on the edge of the black hole's event horizon, where two particles (a negatively charged one and a positively charged one, since energy cannot be created out of nothing) spontaneously appear and immediately cancel each other out, and disappear. However, when on a black hole's event horizon, one particle is sucked in before they destroy eachother. Then, the particle leaves and survives! The same kind of aspect can be applied to discover black hole evaporation, where a singularity slowly weathers away. In short, Quantum Mechanics is extremely important to modern day physics.
The Grand Unification Theory used to be called the Unified Field Theory. It is a search for a theoretical/mathematical framework that can account for and unite all the basic forces, and therefore be considered a Theory of Everything. Currently there are 2 important branches of physics which seem to contradict each other. General Relativity which explains the behaviour of big systems and Quantum Mechanics which explains the behaviour of small systems (atomic/sub-atomic.) If you apply the wrong theory for the size of system then predictions from the theory don't match experimental results. (i.e. The theory is wrong!) Many physisists think there is a theory that can adequately explain both of these systems but they haven't found it yet. Einstein spent his last years attempting to find it. He did not. M theory, a development of string theory is currently considered by many to be the best prospect for a Grand Unification Theory.
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.
There is no quantum physics of a moose. Quantum physics is a type of theoretical physics, and its laws do not apply to physical objects
It can, but other forces (like the Strong Nuclear Force) also balance out the electromagnetic force. This gets into quantum mechanics, and the centrifugal force doesn't really apply a whole lot.
Nothing. Quantum physics does not apply to physical things.
Only that it doesn't manage to explain as much as modern physics (quantum physics, and the Theory of Relativity). Please note that for many practical purposes, classical physics is entirely adequate. For example, when the speeds involved are much lower than the speed of light, you can simply add velocities, rather than use the more complicated Lorentz transformations.
the force apply on string it vibrate this vibration is called tension of the string
In quantum mechanics, electromagnetism is mediated by the gauge boson known as the virtual photon. In classical mechanics, it is a "light wave". Somewhere where the two play reasonably well together, it is a "real photon". EM energy has no "form", only models we apply to it. Saying it is like something big we have experience with, to convey some properties we recognize.
The main limitation on Newtonian Mechanics is the size of the objects. As the object gets smaller, it becomes harder for Newtonian Mechanics to apply its laws.
