New Study Concludes Math Gender Gap Is Cultural, Not Biological 472

New submitter germansausage writes "A new study was published today in Notices of the American Mathematical Society, looking at data from 86 countries, to test the 'greater male variability hypothesis' as the primary reason for the scarcity of outstanding women mathematicians. It concludes that cultural and not biological factors are the chief causes (PDF) of the gap in math skills between men and women."

Ancient Puzzle Gets New Lease on 'Geomagical' Life 73

techbeat writes "An ancient mathematical puzzle has found a new lease on life, reports New Scientist. The magic square is the basis for Sudoku, pops up on the back of a turtle in Chinese legend and provides a playful way to introduce children to arithmetic. But all this time it has been concealing a more complex geometrical form, says recreational mathematician Lee Sallows. He recently released dozens of examples of his 'geomagic squares' online. 'To come up with this after thousands of years of study of magic squares is pretty amazing,' blogged author Alex Bellos. Magic squares are used to help create codes for transmitting information and in the design of drug trials so geomagic ones may have real-world uses, says mathematician Peter Cameron. New Scientist has also put up a gallery of the geomagic squares."
