Wolfram Research Releases Mathematica 7 234

mblase writes "Wolfram Research has released the seventh version of Mathematica, and it does a lot more than symbolic algebra. New features range from things as simple as cut-and-paste integration with Microsoft Word's Equation Editor to instant 3D models of mathematical objects to the most expensive clone of Photoshop ever. Full suites of genome, chemical, weather, astronomical, financial, and geodesic data (or support for same) is designed to make Mathematica as invaluable for scientific research as it is for mathematics."

Stanford To Offer Free CS and Robotics Courses 247

DeviceGuru writes "Stanford University will soon begin offering a series of 10 free, online computer science and electrical engineering courses. Initial courses will provide an introduction to computer science and an introduction to field of robotics, among other topics. The courses, offered under the auspices of Stanford Engineering Everywhere (SEE), are nearly identical to standard courses offered to registered Stanford students and will comprise downloadable video lectures, handouts, assignments, exams, and transcripts. And get this: all the courses' materials are being released under the Attribution-Noncommercial-Share Alike 3.0 Unported license."

Art with a Mathematical Twist 69

Euler points out a story about art created through mathematics. The Science News article covers selections from a recent exhibit, where over 40 artists gathered to show their work and the math behind it. The rest of the pieces are also viewable at the exhibit's website. "Michael Field, a mathematics professor at the University of Houston, finds artistic inspiration in his work on dynamical systems. A mathematical dynamical system is just any rule that determines how a point moves around a plane. Field uses an equation that takes any point on a piece of paper and moves it to a different spot. Field repeats this process over and over again--around 5 billion times--and keeps track of how often each pixel-sized spot in the plane gets landed on. The more often a pixel gets hit, the deeper the shade Field colors it."
