Louis de Broglie's early results on the pilot wave theory were presented in his thesis (1924) in the context of atomic orbitals where the waves are stationary.Early attempts to develop a general formulation for the dynamics of these guiding waves in terms of a relativistic wave equation were unsuccessful until in 1926 Schrödinger developed his non-relativistic wave equation.
The Jahrbuch über die Fortschritte der Mathematik (Yearbook on the Progress of Mathematics) was internationally the first comprehensive journal of abstracts in the history of mathematics. It contains information about almost all of the most important publications in mathematics and their areas of application from the period 1868 to 1942.
This article describes the mathematics of the Standard Model of particle physics, a gauge quantum field theory containing the internal symmetries of the unitary product group SU(3) × SU(2) × U(1). The theory is commonly viewed as describing the fundamental set of particles – the leptons , quarks , gauge bosons and the Higgs boson .

The Mathematical Intelligencer publishes a variety of contributions on and about mathematics. [9] In addition to articles of a strictly mathematical nature, shorter “notes,” poetry, short fiction, and the occasional interview, the journal currently features regular columns on the history of mathematics (“Years Ago” overseen by Jemma Lorenat), humor (“Mathematically Bent” written by ...
MathSciNet is a searchable online bibliographic database created by the American Mathematical Society in 1996. [2] It contains all of the contents of the journal Mathematical Reviews (MR) since 1940 along with an extensive author database, links to other MR entries, citations, full journal entries, and links to original articles.
The AEA maintains EconLit, a searchable data base of citations for articles, books, reviews, dissertations, and working papers classified by JEL codes for the years from 1969. A recent addition to EconLit is indexing of economics journal articles from 1886 to 1968 [ 1 ] parallel to the print series Index of Economic Articles .
SageMath is designed partially as a free alternative to the general-purpose mathematics products Maple and MATLAB. It can be downloaded or used through a web site. SageMath comprises a variety of other free packages, with a common interface and language. SageMath is developed in Python.
