quantum mechanics
Quantum Mechanics is the science of subatomic particles and their behavior patterns that are observed in nature. As the foundation of scientific knowledge approached the start of the twentieth century, problems began to arise over the fact that classic physical ideas were not capable of explaining the observed behavior of subatomic particles. In 1913, the Danish physicist Neils Bohr, proposed a successful quantum model of the atom that began the process of a more defined understanding of its subatomic particles. It was accepted in the early part of the twentieth century that light traveled as both waves and particles. The reason light appears to act as a wave and particle is because we are noticing the accumulation of many light particles distributed over the probabilities of where each particle could be. In 1923, Louis De Broglie hypothesized that subatomic particles exhibit wavelike and particle properties for the same reason. The success of these theories inspired physic!ists to developed a way to describe the behavior of subatomic phenomena in terms of both waves and particles by means of mathematics.
Heisenberg realized that the uncertainty relations had profound implications. This observance is what Werner Heisenberg refereed to as the principle of uncertainty, which commonly became known as Heisenberg's Uncertainty Principle. Quantum mechanics fails to provide deterministic, single-valued solutions to any problem. We have the illusion that position and momentum can co-exist in l!arge objects whose inherent action is huge compared to subatomic particles. This led to much easier calculations and more familiar visualizations of atomic events than did Heisenberg's matrix mechanics. The simultaneous measurement of two conjugate variables such as the momentum and position or the energy and time for a moving particle entails a limitation on the precision of each measurement. In a changing environment, as is the nature of the electron, classical physical attributes of position and momentum are fleeting phenomena. Heisenberg, and others showed that the new quantum mechanics could account for many of the properties of atoms and atomic events. ------------------------------------------------------------------------**Bibliography**. Scientists gladly welcomed Schrodinger's alternative wave mechanics when it appeared in early 1926 since it entailed more familiar concepts and equations. Classical physics assumes all collisions and locations of particles can be measured at once. We can state that the probability of finding the object at each point is high or low, but we can never say with certainty where the object will be at a future time. But, as Bohr's Copenhagen interpretation goes on to suggest, our quantum theories are simply man made generalizations formulated to account for our observations. He relied on what can be observed, namely the light emitted and absorbed by the atoms. An electron cannot be observed without changing its state.
