    en.wikipedia.org/wiki/Madison_Symmetric_Torus

    The Madison Symmetric Torus (MST) is a reversed field pinch (RFP) physics experiment with applications to both fusion energy research and astrophysical plasmas. MST is located at the Center for Magnetic Self Organization (CMSO) at the University of Wisconsin-Madison .

  3. Two-body problem - Wikipedia

    en.wikipedia.org/wiki/Two-body_problem

    [2] Let x 1 and x 2 be the vector positions of the two bodies, and m 1 and m 2 be their masses. The goal is to determine the trajectories x 1 (t) and x 2 (t) for all times t, given the initial positions x 1 (t = 0) and x 2 (t = 0) and the initial velocities v 1 (t = 0) and v 2 (t = 0). When applied to the two masses, Newton's second law states that

  4. List of unsolved problems in physics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.

  5. AP Physics 2 - Wikipedia

    en.wikipedia.org/wiki/AP_Physics_2

    Advanced Placement (AP) Physics 2 is a year-long introductory physics course administered by the College Board as part of its Advanced Placement program. It is intended to proxy a second-semester algebra-based university course in thermodynamics , electromagnetism , optics , and modern physics . [ 1 ]

  6. Minimum spanning tree - Wikipedia

    en.wikipedia.org/wiki/Minimum_spanning_tree

    A planar graph and its minimum spanning tree. Each edge is labeled with its weight, which here is roughly proportional to its length. A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. [1]

  7. Distributed minimum spanning tree - Wikipedia

    en.wikipedia.org/wiki/Distributed_minimum...

    Example of a MST: The minimum spanning tree of a planar graph.Each edge is labeled with its weight, which here is roughly proportional to its length. The distributed minimum spanning tree (MST) problem involves the construction of a minimum spanning tree by a distributed algorithm, in a network where nodes communicate by message passing.

  8. Three-body problem - Wikipedia

    en.wikipedia.org/wiki/Three-body_problem

    Historically, the first specific three-body problem to receive extended study was the one involving the Earth, the Moon, and the Sun. [2] In an extended modern sense, a three-body problem is any problem in classical mechanics or quantum mechanics that models the motion of three particles.

  9. Minimum bottleneck spanning tree - Wikipedia

    en.wikipedia.org/wiki/Minimum_bottleneck...

    K(i) = 2 k(i − 1) with k(1) = 2. The algorithm finds λ * in which it is the value of the bottleneck edge in any MBSA. After λ * is found any spanning arborescence in G ( λ * ) is an MBSA in which G ( λ * ) is the graph where all its edge's costs are ≤ λ * .
