    String theorist Lubos Motl referred to the website as a "very promising competition [to Physics Stack Exchange]". [ 21 ] The University of Stavanger 's cosmology department commented that PhysicsOverflow "seems to implement some interesting ideas", and that "it makes some sense the [ sic ] review the reviewing process".

  5. Exchange interaction - Wikipedia

    en.wikipedia.org/wiki/Exchange_interaction

    In chemistry and physics, the exchange interaction is a quantum mechanical constraint on the states of indistinguishable particles. While sometimes called an exchange force , or, in the case of fermions, Pauli repulsion , its consequences cannot always be predicted based on classical ideas of force . [ 1 ]

  7. Outline of physics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_physics

    Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...

  8. Lorentz covariance - Wikipedia

    en.wikipedia.org/wiki/Lorentz_covariance

    In relativistic physics, Lorentz symmetry or Lorentz invariance, named after the Dutch physicist Hendrik Lorentz, is an equivalence of observation or observational symmetry due to special relativity implying that the laws of physics stay the same for all observers that are moving with respect to one another within an inertial frame. It has also ...

  9. Delta potential - Wikipedia

    en.wikipedia.org/wiki/Delta_potential

    Source: [1] The potential splits the space in two parts (x < 0 and x > 0).In each of these parts the potential is zero, and the Schrödinger equation reduces to =; this is a linear differential equation with constant coefficients, whose solutions are linear combinations of e ikx and e −ikx, where the wave number k is related to the energy by =.
