  2. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.

  4. Faltings's theorem - Wikipedia

    en.wikipedia.org/wiki/Faltings's_theorem

    Faltings's theorem is a result in arithmetic geometry, according to which a curve of genus greater than 1 over the field of rational numbers has only finitely many rational points.

  5. Frame of reference - Wikipedia

    en.wikipedia.org/wiki/Frame_of_reference

    In physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system, whose origin, orientation, and scale have been specified in physical space. It is based on a set of reference points , defined as geometric points whose position is identified both mathematically (with numerical coordinate values) and ...

  6. Mathematical model - Wikipedia

    en.wikipedia.org/wiki/Mathematical_model

    It is common to use idealized models in physics to simplify things. Massless ropes, point particles, ideal gases and the particle in a box are among the many simplified models used in physics. The laws of physics are represented with simple equations such as Newton's laws, Maxwell's equations and the Schrödinger equation. These laws are a ...

  7. Ensemble (mathematical physics) - Wikipedia

    en.wikipedia.org/wiki/Ensemble_(mathematical...

    The formulation of statistical ensembles used in physics has now been widely adopted in other fields, in part because it has been recognized that the canonical ensemble or Gibbs measure serves to maximize the entropy of a system, subject to a set of constraints: this is the principle of maximum entropy.

  8. Physics - Wikipedia

    en.wikipedia.org/wiki/Physics

    Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.

  9. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    In mathematical physics, scattering theory is a framework for studying and understanding the interaction or scattering of solutions to partial differential equations. In acoustics , the differential equation is the wave equation , and scattering studies how its solutions, the sound waves , scatter from solid objects or propagate through non ...
