Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical...

Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution...

Soundproofing is any means of impeding sound propagation. There are several methods employed including increasing the distance between the source and receiver...

A measuring instrument is a device to measure a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity...

In solid state physics, a charge carrier is a particle or quasiparticle that is free to move, carrying an electric charge, especially the particles that...

George E. Pake (April 1, 1924 – March 4, 2004) was a physicist and research executive primarily known for helping found Xerox PARC. Pake was raised in...

In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally...

A non-inertial reference frame (also known as an accelerated reference frame) is a frame of reference that undergoes acceleration with respect to an inertial...

In astronautics, the Hohmann transfer orbit (/ˈhoʊmən/) is an orbital maneuver used to transfer a spacecraft between two orbits of different altitudes...

Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness...

Global terrestrial stilling is the decrease of wind speed observed near the Earth's surface (~10-meter height) over the last three decades (mainly since...

In the context of chemistry, molecular physics, physical chemistry, and molecular modelling, a force field is a computational model that is used to describe...

In theoretical physics, the superconformal algebra is a graded Lie algebra or superalgebra that combines the conformal algebra and supersymmetry. In two...

In astronomy, optics and particle physics, the Bose–Einstein correlations refer to correlations between identical bosons (like the photon, the quanta of...

In quantum computing, quantum memory is the quantum-mechanical version of ordinary computer memory. Whereas ordinary memory stores information as binary...

Scanning tunneling spectroscopy (STS), an extension of scanning tunneling microscopy (STM), is used to provide information about the density of electrons...

Computational mechanics is the discipline concerned with the use of computational methods to study phenomena governed by the principles of mechanics. Before...

The Worldwide LHC Computing Grid (WLCG), formerly (until 2006) the LHC Computing Grid (LCG), is an international collaborative project that consists of...

The ions and electrons of a plasma interacting with the Earth's magnetic field generally follow its magnetic field lines. These represent the force that...

The following is a partial list of notable theoretical physicists. Arranged by century of birth, then century of death, then year of birth, then year of...
