"Late last month, Curtis Cooper of the University of Central Missouri moved one small step closer to Euclid's infinity, when he announced that 257,885,161-1 is prime. This is now the largest known prime number, eclipsing the previous record-holder, which had been discovered at UCLA in 2008. The new number has 17,425,170 digits-just writing them down makes for a 22.45-megabyte text file. The UCLA number had knocked an earlier number of Cooper's, from 2006, out of the record books. "
Mathematics teachers disagreeing with the math teaching methods espoused by the Khan Academy, including words from a Stanford PhD candidate: ""When you attempt to distribute mathematics through any of these media [such as YouTube videos, digital photos, MP3s, PDFs, blog posts, spoken words, and printed text] it changes the definition of mathematics."
Abstract "This article reports on a case study of the web-based educational maths application, Mathletics. The findings are drawn from an ethnographic study of children's technology use in Melbourne, Australia. We explore the experience, governance and commerce of children's Mathletics use, and offer insights into the developing possibilities and challenges emerging through the adoption of Web 2.0 applications for learning and education."

"This engaging book presents the essential mathematics needed to describe, simulate, and render a 3D world. Reflecting both academic and in-the-trenches practical experience, the authors teach you how to describe objects and their positions, orientations, and trajectories in 3D using mathematics. The text provides an introduction to mathematics for game designers, including the fundamentals of coordinate spaces, vectors, and matrices. It also covers orientation in three dimensions, calculus and dynamics, graphics, and parametric curves. "Visit the book's companion web site, gamemath.com, to download the example code and access other resources.
Text from an interview with John H. Barrow, Professor of Mathematical Sciences at the University of Cambridge, discussing history of cultural understanding of infinity, as well as different understandings of infinity - mathematical, physical, cosmological
Cornell and Duke University presses jointly publish the online math journal community Project Euclid and recently announced that MathJax software would used for rendering equations in articles
Mathematics and Multimedia GeoGebra Step-by-Step Tutorial Series
The objective of the GeoGebra Step-by-Step Tutorial Series is not only to teach the readers how to use the software, but also to suggest how to use GeoGebra in teaching and learning mathematics. Most of the tutorials are (or will be) linked to related articles containing explanations and proofs about the mathematics discussed in the tutorials.
An article examines the use of drawing in science learning, starting from the history of drawing in experimental science. Unfortunately the full text requires a subscription. Thinking of implications for math learning.
