Facts about Mechanics

Quantum mechanics has superseded classical mechanics at the foundational level and is indispensable for the explanation and prediction of processes at molecular, atomic, and subatomic levels.

The major division of the discipline of mechanics is one that separates classical mechanics from quantum mechanics.

Particles are bodies with little-known internal structure, treated as mathematical points in classical mechanics.

During the early modern period, scientists such as Galileo, Johannes Kepler, and especially Isaac Newton, laid the foundations for what is now known as classical mechanics.

Classical mechanics has especially often been viewed as a model for other so-called exact sciences.

Important aspects of the fields of mechanical engineering, aerospace engineering, civil engineering, structural engineering, materials engineering, biomedical engineering and biomechanics were spawned from the study of mechanics.

Historically, classical mechanics came first, while quantum mechanics is a comparatively recent formulation.

Mechanics also constitutes a central part of technology, the application of physical knowledge for human purposes.

The following two lists indicate various subjects that are studied under classical mechanics and quantum mechanics.

Analyses indicate that the Somali ostrich may be better considered a full species.

Studies in mechanics have made vital contributions to various fields of engineering.

Quantum mechanics is now considered a foundational-level theory that encompasses and supersedes classical mechanics.

Other distinctions between the various sub-disciplines of mechanics, concern the nature of the bodies being described.

Quantum mechanics is of a wider scope, as it encompasses classical mechanics as a sub-discipline that is applicable under certain restricted circumstances.

Relativistic corrections are also needed for quantum mechanics, although relativity has not been fully integrated with it yet.

Modern mechanics encompasses the movement of all matter in the universe under the four fundamental interactions (or forces): gravity, the strong and weak interactions, and the electromagnetic interaction.

Classical mechanics originated with Isaac Newton's Laws of motion in Principia Mathematica, while quantum mechanics did not appear until 1900.

Mechanics is the original discipline of physics and was formerly part of "natural philosophy," dealing with forces and motion in the macroscopic world as perceived by the human eye.
