Parent topics
- Physics [r]: The study of forces and energies in space and time. [e]
- Chemistry [r]: The science of matter, or of the electrical or electrostatical interactions of matter. [e]
- Engineering [r]: a branch of engineering that uses chemistry, biology, physics, and math to solve problems involving fuel, drugs, food, and many other products. [e]
Subtopics
- Astrophysics [r]: Hybrid of Physics and Astronomy that attempts to explain the physical workings of the celestial objects and phenomena. [e]
- Chemical engineering [r]: a branch of engineering that uses chemistry, biology, physics, and math to solve problems involving fuel, drugs, food, and many other products [e]
- Matter [r]: Please do not use this term in your topic list, because there is no single article for it. Please substitute a more precise term. See Matter (disambiguation) for a list of available, more precise, topics. Please add a new usage if needed.
- Pressure [r]: A ratio equal to the force applied perpendicular to the surface of the area divided by that area (force/area). [e]
- Space (physics) [r]: A fundamental quantity in physics - that which is between two positions at a given time. Following the International System of Units (SI), the space between any two positions can be measured in meters. [e]
- Vacuum (quantum electrodynamic) [r]: The term quantum electrodynamic vacuum, or QED vacuum, refers to the ground state of the electromagnetic field, which is subject to fluctuations about a dormant zero average-field condition. [e]
- Vacuum (classical) [r]: The term classical vacuum as used in classical electromagnetism and in the definition of the SI units refers to an ideal reference medium devoid of all particles, with ideal properties. These ideal properties include: independence from field strengths, direction, frequency, or polarization, and from temperature. [e]
- Atmosphere (unit) [r]: A unit of pressure measurement (symbol: atm) defined as 101,325 pascal. [e]
- Atmospheric pressure [r]: The ambient air pressure at any given point in Earth's atmosphere. [e]
- Electric constant [r]: A physical constant in the International System of Units (SI) relating capacitance to area in classical vacuum with an exact value ε0 = 107/(4πc02) F/m, c0 being the defined value for the speed of light in classical vacuum in the SI units. [e]
- Gas [r]: One of the major states of matter (i.e., gas, liquid, solid and plasma). [e]
- Magnetic constant [r]: A physical constant in the International System of Units (SI) relating mechanical force and electric current in classical vacuum with a defined value μ0 = 4π × 10−7 N/A2. [e]
- Relative permeability [r]: A factor describing magnetizability as a proportionality between magnetic flux density and magnetic field in a magnetic material or medium. [e]
- Vacuum distillation [r]: The laboratory or industrial-scale distillation of liquids performed at a pressure lower than atmospheric pressure. [e]
- Vacuum energy [r]: Add brief definition or description
- Vacuum pump [r]: Add brief definition or description
- Zero-point energy [r]: The lowest possible energy that a quantum mechanical physical system may possess; it is the energy of the ground state of the system. [e]
