Math Model Helps Answer Riddle of Tiger's Stripes

Researchers can better explain why they're vertical or horizontal

(Newser) - Since the 1950s mathematicians have been trying to sort out exactly why some animals, like tigers and zebras, have stripes that are oriented perpendicularly to their spines, while others, like the zebrafish, have stripes that are parallel. Now Harvard researchers are proposing a mathematical model in the journal Cell Systems...

Man Behind Secret Code at CIA Offers New Hint

Kryptos' final secret message includes phrase 'Berlin clock'

(Newser) - Jim Sanborn punched four messages into his curved copper sculpture, which has sat outside CIA headquarters in Langley, Va., since 1990. The first three messages of "Kryptos" were decoded by NSA cryptographers in 1993, then by fans in 1999. The 97-character fourth message, however, has stumped code breakers for...

Computer Fools Humans, Passes 64-Year-Old Test

Said to be first to pass 'Turing Test'

(Newser) - A landmark in the realm of artificial intelligence has been achieved. In 1950, computer scientist Alan Turing suggested a test which, in its current form, requires a computer to "trick" 30% of judges into believing it's human. At London's 2014 Turing Test on Saturday, 33% of judges...

(Newser) - Alan Turing, widely hailed as the father of modern computing, helped the Allies win World War II by cracking Nazi Germany's Enigma code—but after the war, Britain repaid him by persecuting him for his homosexuality, leading to a conviction for gross indecency in 1952, followed by chemical castration...

Google Doodle Offers Brain-Teaser Tribute

It honors mathematician Alan Turing

(Newser) - Google today honors pioneering mathematician Alan Turing with one of its more ambitious Google Doodles. As USA Today explains, it simulates one of his theoretical concepts, a Turing Machine. "There are six puzzles to solve, one for each letter in the Google logo," writes Nancy Blair. "After...

British PM Apologizes to Gay WWII Codebreaker

Gordon Brown slams 'horrifying' treatment of late mathematician Alan Turing

(Newser) - Gordon Brown has issued a posthumous apology to WWII codebreaking genius Alan Turing, the Guardian reports.
