Wolfram Research
Wolfram Math World: Foundations of Mathematics: Topics
This math tutorial site covers set theory, axioms, category theory, logic, mathematical problems, and point-set topology.
Wolfram Research
Wolfram Math World: Closed Set
Site gives four different definitions of a closed set in mathematics. Each of the definitions has at least one link for further clarification. The site also expresses which of these definitions is most commonly encountered.
Texas Instruments
Texas Instruments: Numb3 Rs: Critical Maths
Based off of the hit television show NUMB3RS, this lesson introduces students to critical path analysis (CPA), in which tasks are broken into subtasks with prerequisites. In such a situation, subtasks must be completed in a certain order...
Wolfram Research
Wolfram Math World: Topology: Topics
A dozen topology topics are listed here for both the teacher's and the student's use. Knot Theory, Bundles, and Topology Structures are just some of the areas which are explored in depth. Detailed explanations and necessary sketches and...
National Council of Teachers of Mathematics
The Math Forum: Ask Dr. Math: Rational and Irrational Number
Math Forum response to the size of the set of rational numbers. Responses investigate the countability of sets and basic set theory.
National Council of Teachers of Mathematics
The Math Forum: Ask Dr. Math: Rational Numbers
Math Forum response addressing how many elements are in the set of rational numbers. Responses investigate the countability of sets, and how sets with an infinite number of elements can be counted and compared to other "infinite sets."
Boston University
Bu: Fractal Geometry of the Mandelbrot Set
This site progresses in iterations through Mandelbrot and Julia sets to explain fractals and the mathematics behind them.
TED Talks
Ted: Ted Ed: Why Do Competitors Open Their Stores Next to One Another?
Discover how game theory and Nash Equilibrium affect where retailers set up businesses to compete with each other. [4:07]
Texas Instruments
Texas Instruments: Numb3 Rs: It's All Connected
Based off of the hit television show NUMB3RS, this lesson uses students' knowledge of graph theory (networks) to introduce two measures of centrality (how connected a particular node is to the entire network), known as degree centrality...
