Discovering the fundamental structure of matter. ... Quantum theory evolved as a new branch of theoretical physics during the first few decades of the 20th century in an endeavour to understand the fundamental properties of matter. It began with the study of the interactions of matter and radiation.

The wavelengths of the Halpha and Hdelta lines lie in the relatively simple ratio 8:5 as shown bp the elementary quantum theory of the Bohr atom. Using a moderately coarse grating it is shown that the fifth-order spectrum of the Halpha line lies over the eight-order spectrum of the Hdelta line.

The foundations of quantum theory are introduced in language understandable to students, ... Everett and Bohm will serve as good representatives of non-standard quantum theorists. There are many others, but we have more to gain by keeping things simple than by allowing ourselves to be overwhelmed by complexity.

As a result there is no self-consistent theory which generalizes the simple, one-particle Schrödinger equation into a relativistic quantum wave equation.

Starting from the exact unified expression of the line profile, a quantum theory is developed making exact allowance for the long-range dipole interaction. The knowledge of the positions of the bound states below the n=2 threshold enables approximation of the contribution of short-range interactions.

Where can I find a simple history of the Quantum Theory? ... Quantum Theory is definitely not easy to understand. It involves concepts and very small sizes far beyond our common sense or ability to observe without very special instruments. Here are some nice web sites on the history: - Thall's History of Quantum Mechanics...

The quantum theory of the atom also had to explain why the electron stays in its orbit, ... The ground state (state with the least energy) of the Quantum Simple Harmonic Oscillator is indeed in a minimum uncertainty state and behaves such that the inequality is an equality. In other words, that's when we can know the most...
