Project Euclid was developed and deployed by the Cornell University Library and is jointly managed by Cornell and the Duke University Press. Project Euclid's mission is to advance scholarly communication in the field of theoretical and applied mathematics and statistics. Project Euclid is designed to address the unique needs of low-cost independent and society journals. Through a collaborative partnership arrangement, these publishers join forces and participate in an online presence with advanced functionality, without sacrificing their intellectual or economic independence or commitment to low subscription prices. Full-text searching, reference linking, interoperability through the Open Archives Initiative, and long-term retention of data are all important components of the project.
MathWorldTM is the web's most extensive mathematical resource, provided as a free service to the world's mathematics and internet communities as part of a commitment to education and educational outreach by Wolfram Research, makers of Mathematica.
Take a look at the specific mathematics used by the GPS receivers on the ground to calculate location on earth, using the two signals (location and timing) emanating from the satellites. The mathematics necessary to understand the system as a whole includes solving systems of equations, equations of circles, equations of spheres, projections, solving (algebracially) a system of 4 spheres, inverse trigonometric functions, the distance formula, the Pythagorean Theorem, the d=rt formula, use of matrices, etc..
The field of Number Theory, as with many fields in mathematics, began as an abstract exercise and eventually found countless applications in the modern world. This page has links to a variety of sites that explore both sides of Number Theory.
FRACTALS are incredibly complex geometric objects that are defined by very simple rules. The one characteristic they all share is that they have self-similarity meaning that if one looks closer and closer into the fractal, one will see smaller and smaller copies of the original, large image imbedded within
Interactive Real Analysis is an interactive website for Real Analysis or Advanced Calculus . It deals with sets, sequences, series, continuity, differentiability, integrability (Riemann and Lebesgue), topology, and more.
Topology is a branch of mathematics that considers mathematical objects without concerning itself with measurement. Length, width, height, distance become irrelevant. Instead, other features of figures that remain the same (invariants) when figures are distorted are studied
