  2. Jefimenko's equations - Wikipedia

    en.wikipedia.org/wiki/Jefimenko's_equations

    In electromagnetism, Jefimenko's equations (named after Oleg D. Jefimenko) give the electric field and magnetic field due to a distribution of electric charges and electric current in space, that takes into account the propagation delay (retarded time) of the fields due to the finite speed of light and relativistic effects.

  3. Video abstract - Wikipedia

    en.wikipedia.org/wiki/Video_abstract

    A video abstract accompanying a journal article. An example extracted from New Journal of Physics.. Video abstracts represent a new genre in science-communication. They can be defined as “peer-to-peer video summaries, three to five minutes long versions of academic papers” [Berkowitz, 2013] [1] that “describe dynamic phenomena which are simply too complicated, too complex, too unusual ...

  4. The Feynman Lectures on Physics - Wikipedia

    en.wikipedia.org/.../The_Feynman_Lectures_on_Physics

    The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". [1] The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1964.

  5. The Character of Physical Law - Wikipedia

    en.wikipedia.org/wiki/The_Character_of_Physical_Law

    The lectures covered the following topics: The law of gravitation, an example of physical law; The relation of mathematics and physics; The great conservation principles; Symmetry in physical law; The distinction of past and future; Probability and uncertainty - the quantum mechanical view of nature; Seeking new laws

  6. Theoretical physics - Wikipedia

    en.wikipedia.org/wiki/Theoretical_physics

    Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics , which uses experimental tools to probe these phenomena.

  7. Theoretical Advanced Study Institute - Wikipedia

    en.wikipedia.org/wiki/Theoretical_Advanced_Study...

    The Theoretical Advanced Study Institute or TASI is a four-week summer school in high-energy physics or astrophysics held yearly at the University of Colorado at Boulder.The school is meant primarily for advanced graduate students and consists of a series of pedagogical lectures on selected topics given by active researchers in the field.

  8. Action principles - Wikipedia

    en.wikipedia.org/wiki/Action_principles

    Action principles are "integral" approaches rather than the "differential" approach of Newtonian mechanics.[2]: 162 The core ideas are based on energy, paths, an energy function called the Lagrangian along paths, and selection of a path according to the "action", a continuous sum or integral of the Lagrangian along the path.

  9. Covariant formulation of classical electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Covariant_formulation_of...

    The covariant formulation of classical electromagnetism refers to ways of writing the laws of classical electromagnetism (in particular, Maxwell's equations and the Lorentz force) in a form that is manifestly invariant under Lorentz transformations, in the formalism of special relativity using rectilinear inertial coordinate systems.
