  2. Hilbert's sixth problem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_sixth_problem

    Hilbert’s sixth problem was a proposal to expand the axiomatic method outside the existing mathematical disciplines, to physics and beyond. This expansion requires development of semantics of physics with formal analysis of the notion of physical reality that should be done. [ 9 ]

Lie's concept of a continuous group of transformations without the assumption of the differentiability of the functions defining the group. 6. Mathematical treatment of the axioms of physics. 7.

  4. Distance of closest approach - Wikipedia

    en.wikipedia.org/wiki/Distance_of_closest_approach

    There is no analytic solution for this problem, since solving for the distance requires the solution of a sixth order polynomial equation. Here an algorithm is developed to determine this distance, based on the analytic results for the distance of closest approach of ellipses in 2D, which can be implemented numerically. Details are given in ...

  5. Relationship between mathematics and physics - Wikipedia

    en.wikipedia.org/wiki/Relationship_between...

    In 1900, David Hilbert in his 23 problems for the advancement of mathematical science, considered the axiomatization of physics as his sixth problem. The problem remains open. [20] As time progressed, the mathematics used in physics has become increasingly sophisticated, as in the case of superstring theory. [21]

  6. Euclidean distance - Wikipedia

    en.wikipedia.org/wiki/Euclidean_distance

    The Euclidean distance is the prototypical example of the distance in a metric space, [10] and obeys all the defining properties of a metric space: [11] It is symmetric, meaning that for all points and , (,) = (,). That is (unlike road distance with one-way streets) the distance between two points does not depend on which of the two points is ...

  7. Metric space - Wikipedia

    en.wikipedia.org/wiki/Metric_space

    In mathematics, a metric space is a set together with a notion of distance between its elements, usually called points. The distance is measured by a function called a metric or distance function. [1] Metric spaces are the most general setting for studying many of the concepts of mathematical analysis and geometry.

  9. Physics - Wikipedia

    en.wikipedia.org/wiki/Physics

    For example, mathematical physics is the application of mathematics in physics. Its methods are mathematical, but its subject is physical. [ 57 ] The problems in this field start with a " mathematical model of a physical situation " (system) and a "mathematical description of a physical law" that will be applied to that system.
