Ed Pegg writes "For Popular Science , Theo Gray demonstrates the Bacon Lance, a flaming meatsword that can cut through steel. Yes, with some ordinary bacon, and some pure oxygen, it's possible to cut through security doors. This comes out right after his profusely illustrated book of science experiments, Mad Science . When he's not working on experiments or his periodic table, Theo's alter-ego is a mild-mannered programmer for Mathematica ."

Ed Pegg writes "Stephen Wolfram has announced an alpha of Wolfram|Alpha. In this blog post, the maker of Mathematica says that "It's certainly the most complex project I've ever undertaken." He further mentions it contains "trillions of pieces of curated data." Over at Wolfram|Alpha itself, there seems to be a sign-up sheet for Wolfram|Alpha alpha-testers."

Ed Pegg writes "Mathematica 7 has launched, as noted in Stephen Wolfram's blog post. Among the new features are huge equation typesetting, transcendental roots, and discrete calculus. Looking back at the version 6 discussion, it's perhaps inevitable that comparisons will be made to CAR, CGsuite, GAP, Geogebra, Geometer's Sketchpad, Geometry Expressions, Geonext, LaTeX, Magma, Maple, Matlab, nauty, noneuclid, Pari, Sage, or SeifertView. In other news, the Wolfram Demonstrations project now has over 4000 interactive math demos."

Ed Pegg writes "A recent NYT Op-Chart looked at 10K invested under different political parties. Theo Gray wondered how inflation, dividends, delay of influence, market timing, and reinvestment would affect everything, and wrote a Stock Market Returns by Presidential Party blog and accompanying interactive Demonstration."

Ed Pegg writes "For those that want to get their fingers stained red and blue with actual political data, resources beyond 538 and pollster can be accessed. In a blog item for Wolfram Research, Jeff Hamrick gives step by step details for how to import raw data from Mason-Dixon, Rasmussen, and Quinnipiac. Then he uses Mathematica to analyze the political data."

Tesla Roadster attacked by CARB-> 0

Ed Pegg writes "The Tesla Roadster was having a good week. Jay Leno just videoblogged it. Anyone who saw Who Killed the Electric Car will recall the villainry of the California Air Resources Board (CARB), which gutted most of the goals for zero-emission vehicles after an oil company stooge, Alan Lloyd, gained control. Most electric cars were then taken back by the automakers and sent to crushers. Now that Tesla Motors is rolling cars off the production line, the CARB is taking a new tactic to penalize Telsa Motors for making clean cars . The CARB public hearing will be March 27th (tomorrow) in Sacramento."

Mathematica 6 launched

Ed Pegg writes "Wolfram Research has just released Mathematica 6. That link, in addition to the usual 'dramatic breakthrough' material, has an amazing flash banner that simultaneously shows a thousand mathematical demonstrations all at once. The animations came from the Wolfram Demonstrations Project, a free service with 1200+ dynamically interactive examples of math, science, and physics (with code). For the product itself, much is new or improved, with built-in math databases, improved visualizations, and more."
