The Math That Predicted the Revolutions Sweeping the Globe Right Now
It's happening in Ukraine, Venezuela, Thailand, Bosnia, Syria, and beyond. Revolutions, unrest, and riots are sweeping the globe. The nearsimultaneous eruption of violent protest can seem random and chaotic; inevitable symptoms of an unstable world. But there's at least one common thread between the disparate nations, cultures, and people in conflict, one element that has demonstrably proven to make these uprisings more likely: high global food prices.

Benford's Law
Benford's law is a phenomenological law also called the first digit law, first digit phenomenon, or leading digit phenomenon. Benford's law states that in listings, tables of statistics, etc., the digit 1 tends to occur with probability ∼30%, much greater than the expected 11.1% (i.e. one digit out of 9).

A fifth of adults have forgotten how to do fractions or percentages
One in five adults (or 20%) has forgotten how to work out either fractions or percentages, and even fewer remember how to calculate the mean, the median or the mode, according to a study. It reveals a perturbing lack of recall among many adults who have forgotten not just the rules of mathematics, but many of the key principles of English and science they were taught at school. In maths, 35% of the 2,000 adults who took part in the...

Majority of mathematicians hail from just 24 scientific ‘families’
Most of the world’s mathematicians fall into just 24 scientific 'families', one of which dates back to the fifteenth century. The insight comes from an analysis of the Mathematics Genealogy Project (MGP), which aims to connect all mathematicians, living and dead, into family trees on the basis of teacher–pupil lineages, in particular who an individual's doctoral adviser was.

When Blind People Do Algebra, The Brain's Visual Areas Light Up
People born without sight appear to solve math problems using visual areas of the brain. A functional MRI study of 17 people blind since birth found that areas of visual cortex became active when the participants were asked to solve algebra problems, a team from Johns Hopkins reports in the Proceedings of the National Academy of Sciences. "And as the equations get harder and harder, activity in these areas goes up in a blind person," says Marina Bedny, an author of the study and an assistant professor in the department of psychological and brain sciences at Johns Hopkins University.
