How This Woman Changed Physics

Emmy Noether may be obscure, but her work was revolutionary

(Newser) - Her work may be the "backbone" of all modern physics; her key theorem could be as important as the theory of relativity; yet hardly anyone knows who Emmy Noether is. Celebrating her 130th birthday this month, Noether has suffered what the New York Times calls "chronic neglect"—...

Girls, Boys Equals at Math

Perceived differences a matter of culture, not biology: study

(Newser) - Cross another stereotype off the list: Any differences between men's and women's math abilities are cultural, not innate, a study finds. Studies that have suggested such differences covered too few countries to give an accurate picture, researchers say. The new study, however, reviewed math scores across 86 countries,...

Mathematician Calculates Pi to 10T Digits

Breaks own previous record of 5T digits

(Newser) - A Japanese man used his homemade computer to calculate the value of pi to 10 trillion digits, breaking the 5-trillion-digit record he himself set last August . Systems engineer Shigeru Kondo, 56, started crunching the numbers on a computer using a 48-terabyte hard drive in October and finished Sunday, the Telegraph...

Forget Pi, Here Comes Tau

Using a new constant would simplify things, say experts

(Newser) - You don't need to be a mathematician to appreciate pi: Children everywhere can tell you it's 3.14, and it's even celebrated on 3-14. But now experts are arguing that pi, which references the ratio of a circle's circumference to its diameter, be replaced with a...

Second-Grade Girls Already Bailing on Math

Study finds stereotype reaches kids strikingly early

(Newser) - A disturbingly high proportion of little girls have absorbed the stereotype that math is for boys by the time they reach the second grade, a new study finds. Researchers found that little boys and girls alike tend to associate enjoyment of math with boys, MSNBC reports. "We still don’...

Religion to Die Out in 9 Nations

Mathematical model points to extinction in Australia, Austria, Ireland

(Newser) - Religion is bound for extinction in nine nations where it's already in decline, according to researchers using mathematical models. The researchers applied the principle of "nonlinear dynamics" to census data from the countries—Australia, Austria, Canada, the Czech Republic, Finland, Ireland, the Netherlands, New Zealand, and Switzerland—and predicted...

Secret Musical Message Found in Plato

Philosopher was closet supporter of Pythagoras

(Newser) - Plato embedded in his writings secret messages that would have earned him execution for heresy, says a scholar who claims to have found a hidden code in the original scroll form of the ancient Greek philosopher's writings. Exactly once every 12 lines Plato refers to music—a message, says scholar...

Math Genius Turned Down $1M Prize 'Because It's Unfair'

Grigory Perelman finally explains

(Newser) - The reclusive Russian genius who solved one of math's most baffling problems has finally explained why he doesn't want the cool million that he won for doing so: It's just not fair. Grigory Perelman, who refused to speak to reporters camped outside his roach-infested St. Petersburg flat after his feat...

Eat some pie, write a 'pi-ku,' and wish Albert Einstein a happy birthday

(Newser) - Today is 3/14, better known to the math-loving community as Pi Day, an international celebration of the irrational number and, for some, its almost-namesake dessert. In honor of the occasion, the iconic logo on the Google homepage has transformed into a collection of formulas that use pi. To celebrate, write...

Girls Learn Math Anxiety From Female Teachers

Instructors transfer bias to students

(Newser) - Girls who buy into the stereotype that boys are better at math may be learning the trait from their own female teachers. Female first-and second-grade teachers worried about their math skills transfer that anxiety onto girls in their classrooms, a new study suggests. Those teachers were more likely to believe...

Scientists 'Tie Light in Knots'

Breakthrough could lead to more precise lasers, traffic speed guns

(Newser) - A team of physicists say they’ve managed to “tie light in knots” using holograms and abstract mathematics. The breakthrough could have a host of practical applications, including more precise lasers and traffic speed guns. It’s also the first physical application of “knot theory,” a branch...

Scientist Smashes Pi Record

He calculates number to 2.7 trillion digits on his home PC

(Newser) - A French scientist shattered the record for calculated digits of Pi, working the number out to 2.7 trillion decimal places—and he did it with a home PC. Fabrice Bellard beat the previous record by 100 billion digits, using a new software algorithm he claims is 20 times faster...

200-Year-Old Presidential Code Cracked

Mathematician unravels cipher that stumped Jefferson

(Newser) - A code that stumped Thomas Jefferson and other cryptologists for over two centuries has finally been cracked, the Wall Street Journal reports. The cipher—sent to Jefferson in 1801 by mathematician Robert Patterson as an example of the perfect code—piqued the interest of defense cryptologist Lawren Smithline, who tackled...

Spooky Universal Pattern Captivates Math Experts

Academics ponder similarities between cities and organisms

(Newser) - A fascinating mathematical similarity between infrastructure requirements of cities and the nutritional needs of different-sized animals has energized a field of study that is enthralling academics.
