Quantum mechanics. Quantum mechanics is the best tool we have to understand how the universe works on its smallest scales. Everything we can see around us, from far-off galaxies to our own bodies ... A fundamental concept in quantum mechanics is that of randomness, or indeterminacy. In general, the theory predicts only the probability of a certain result. Consider the case of radioactivity.

Quantum mechanics is a linear theory, and so it is natural that vector spaces play an important role in it. A physical state is represented mathematically by a vector in a Hilbert space (that is, vector spaces on which a positive-definite scalar product is defined); this is called the space of states. Physical properties like momentum, position ...

Nov 29, 2000 · Quantum mechanics is, at least at first glance and at least in part, a mathematical machine for predicting the behaviors of microscopic particles — or, at least, of the measuring instruments we use to explore those behaviors — and in that capacity, it is spectacularly successful: in terms of power and precision, head and shoulders above any theory we have ever had. The game involves two sources distributing entangled qubits to three observers, who calculate a “score” from measurements performed on the qubits. In both experiments, the obtained score isn’t compatible with a real-valued, traditional formulation of quantum mechanics. Complex numbers are widely exploited in classical and relativistic ...The index n n is called the energy quantum number or principal quantum number.

Mathematically, quantum mechanics can be regarded as a non-classical probability calculus resting upon a non-classical propositional logic. More specifically, in quantum mechanics each probability-bearing proposition of the form “the value of physical quantity \(A\) lies in the range \(B\)” is represented by a projection operator on a Hilbert …It introduces some of the important model systems studied in contemporary physics, including two-dimensional electron systems, the fine structure of hydrogen, lasers, and particle scattering.
