Vor 4 Tagen · Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.
Vor 5 Tagen · SI. J · K −1. L 2 · M · T −2 · Θ −1. Beim Schmelzen von Eis wird die geordnete Eiskristallstruktur in eine ungeordnete Bewegung einzelner Wassermoleküle überführt: Die Entropie des Wassers im Eiswürfel nimmt dabei zu. Die Entropie ist eine in der Thermodynamik definierte physikalische Größe von fundamentaler Bedeutung.
Vor 2 Tagen · Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Vor 4 Tagen · Spin (physics) Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2] : 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory .
Vor 4 Tagen · In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
Vor 3 Tagen · t. e. In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise.
Vor 4 Tagen · Historical background See also: History of quantum field theory, History of subatomic physics, Julian Schwinger, and John Clive Ward In 1954, Yang Chen-Ning and Robert Mills extended the concept of gauge theory for abelian groups, e.g. quantum electrodynamics, to nonabelian groups to provide an explanation for strong interactions. In 1957, Chien-Shiung Wu demonstrated parity was not conserved ...
