Quantum Theory Essay

The Quantum TheoryThe Quantum Theory, also quantum mechanics, is a theory in physics based on using the concept of the quantum unit to describe the dynamic properties of subatomic particles and the interactions of matter and radiation. The foundation was laid by the German physicist Max Planck, who hypothesized in 1900 that energy can be given off or absorbed by matter only in small, discrete units called quanta. Also important to the development of quantum mechanics was the uncertainty principle, founded by the German physicist Werner Heisenbera in 1927, which states that the position and momentum of a subatomic particle cannot be specified simultaneously.In the 18th and 19th centuries, Newtonian, or classical, mechanics appeared to provide a complete and accurate description of the motions of bodies""for example, planetary motion. In the late 19th and early 20th centuries, however, experimental findings raised doubts about the completeness of Newtonian theory. Among the later observations were the lines that appear in the spectra of light emitted by heated gases in which electric discharges take place. From the model of the atom developed in the early 20th century, by the English physicist Ernest Rutherford, in which negatively charged electrons circle a positive nucleus in orbits prescribed by Newton's laws of motion, scientists had also expected that the electrons would emit light over a broad frequency range, rather than in the narrow frequency ranges that form the lines in a spectrum.Another enigma for physicists was the coexistence of two theories of light, the corpuscular theory, which explains light as a stream of particles, and the wave theory, which views light as electromagnetic waves. A third problem was the absence of a molecular basis for thermodynamics. In his book Elementary Principles in Statistical Mechanics (1902), the American mathematical physicist J. Willard Gibbs conceded the impossibility of framing a theory of molecular action that reconciled thermodynamics, radiation, and electrical phenomena as they were then understood.At the turn of the century physicists did not yet clearly recognize that these and other difficulties in physics were in any way related. The first development that led to the solution of these difficulties was Planck's introduction of the concept of the quantum, as a result of physicists' studies of blackbody radiation during the closing years of the 19th century. A body at a moderately high temperature gives off most of its radiation in the low frequency regions; a body at a higher temperature gives off comparatively more radiation in higher frequencies. During the 1890s physicists conducted detailed quantitative studies of these phenomena and expressed their results in a series of curves or graphs. The classical, or prequantum, theory predicted an altogether different set of curves from those actually observed. What Planck did was to devise a mathematical formula that described the curves...

We use the quantum theory
