Indian claims finding new cube root formula: "Agra: It has eluded experts for centuries, but now an Indian, following in the footsteps of Aryabhatt, one of the earliest Indian mathematicians, claims to have worked out a simple formula to find any number's cube root.

Nirbhay Singh Nahar, a retired chemical engineer and an amateur mathematician, claims he has found a formula that will help students and applied engineers to work out the cube roots of any number in a short time.

"Give me any number - even, odd, decimals, a fraction...and I will give you the cube root using a simple calculator to just add and subtract within a minute and a half. We do have methods and patterns, but no formula at the moment. Even the tables give cube roots of 1 to 1,000, not of fractions or of numbers beyond 1,000, for which people have to use scientific calculators," Nahar, who retired as an engineer from Hindustan Salts Ltd at Sambhar (Rajasthan), said."

Who Owns Your Personal History? | Fast Company: "One day in December 1955, former President Harry Truman, who had been living in Independence, Missouri since leaving the White House in 1953, arrived home and found his wife Bess at the fireplace, burning a pile of his letters to her.   “Think of history,” he said. "I have," she replied. And she let the letters continue to burn. Today, we no longer have the option of burning our letters. Our digital tracks are everywhere--in email messages, tweets, text messages, social networking postings, and the visit histories of Internet sites. They are in the hands of family members, friends, acquaintances, current and former coworkers, people we barely remember, and people we prefer to forget. Our movements are logged through mobile devices, and our images are stored in the surveillance archives of retail stores, office buildings, taxis, and transit systems."

Wolfram Blog : Happy 10*9*8+7+6-5+4*321 !: "A quick check with Mathematica verified that, yes indeed, 10*9*8+7+6-5+4*321 = 2012. Wow! How in the world did anyone discover that rare factoid? And how long will it be until another year arrives that can be similarly expressed?"

Computing: Improving security in the cloud: "Less and less of today's computing is done on desktop computers; cloud computing, in which operations are carried out on a network of shared, remote servers, is expected to rise as the demand for computing power increases. This raises some crucial questions about security: Can we, for instance, perform computations on data stored in "the cloud" without letting anyone else see our information? Research carried out at the Weizmann Institute and MIT is moving us closer to the ability to work on data while it is still encrypted, giving an encrypted result that can later be securely deciphered."

Computer simulations shed light on the physics of rainbows: "Computer scientists at UC San Diego, who set out to simulate all rainbows found in nature, wound up answering questions about the physics of rainbows as well. The scientists recreated a wide variety of rainbows -- primary rainbows, secondary rainbows, redbows that form at sunset and cloudbows that form on foggy days -- by using an improved method for simulating how light interacts with water drops of various shapes and sizes. Their new approach even yielded realistic simulations of difficult-to-replicate "twinned" rainbows that split their primary bow in two."
