Submission + - Sprint Fights AT&T-T-Mobile Deal In W. Va. (

RedEaredSlider writes: Sprint is taking its battle against the merger of AT&T and T-Mobile to the state public utility commissions.

The No. 3 wireless company in the U.S. has formally contested the $39 billion deal between T-Mobile and AT&T, writing to the Public Service Commission of West Virginia, which oversees public utilities and telecommunications companies.

In its letter, Sprint says the merger will hurt competition. The letter also states that the merger does not make AT&T better able to deploy next-generation networks in the state. In addition, the merger would result in a duopoly of AT&T and Verizon.


Submission + - More Evidence for Water on Titan (

gpronger writes: Researchers using data from NASA's Cassini continue to build evidence that Titan is composed of a frozen outer "shell", a layer of liquid water, and then a solid core.

"We think that the presence of an internal ocean is likely," said study lead author Rose-Marie Baland of the Royal Observatory of Belgium in Brussels.

This is based upon calculations starting from prior work and reviewing orbital data that the best fit is if Titan has a subsurface ocean.


Submission + - Hewlett Packard's Cult Calculator Turns 30

Hugh Pickens writes writes: "The Wall Street Journal reports that Hewlet Packard's HP-12C financial calculator has remained outwardly unchanged since its introduction in 1981. "Once you learned it on the 12C, there was no need to change," says David Carter, chief investment officer of New York wealth-management firm Lenox Advisors, who has owned his 12C for 22 years and still keeps it on his desk. "It's not like the math was changing." The 12C, which costs $70 on HP's website, is HP's best-selling calculator of all time, though the company won't reveal how many units it has sold over the years and the 12C still uses on an unconventional mathematical notation called "Reverse Polish Notation," which eschews parentheses and equal signs in an effort to run long calculations more efficiently which may be one reason users are reluctant to switch and tends to render the calculator mystifying to the novice user. New employees in financial services businesses quickly learn that ignorance of the 12C can flash more warning signs than a scuffed pair of shoes. "The guy with the totally beat-up HP-12C — you know he's actually done things in business," says James Granberry, a student at Vanderbilt University's Owen Graduate School of Management. "And then there's the young guy who looks like he may have put on his suit for the first time—with a graphing calculator." The HP-12C is one of only four calculators permissible in the Chartered Financial Analyst exams, the others being its sister, the HP-12C Platinum, and the Texas Instruments BA II Plus and BA II Plus Professional."

Submission + - Rogue Wave Recreated in Lab (

sciencehabit writes: Toy boats beware! For the first time, physicists have created a rogue wave in a laboratory tank. Although the 3-centimeter-tall wave would topple only a tiny model ocean liner, the observation lends credence to the idea that a simplified theory of water waves can explain freak waves, which have been blamed for sinking real ships.

Submission + - Forty Years of P v NP

An anonymous reader writes: In the afternoon of May 4, 1971, in the Stouffer's Somerset Inn in Shaker Heights, Ohio, Steve Cook presented his STOC paper proving that Satisfiability is NP-complete and Tautology is NP-hard.

The theorems suggest that Tautology is a good candidate for an interesting set not in [P] and I feel it is worth spending considerable effort trying to prove this conjecture. Such a proof would be a major breakthrough in complexity theory.

And thus Cook formulated what was soon to be called the P versus NP problem. The rest is history.

Here's the 1971 STOC Program (there were 143 attendees)and what that sacred ground looks like today.
