Math Genius Has Come Up With a Wildly Simple New Way to Solve Quadratic Equations
If you studied algebra in high school (or you're learning it right now), there's a good chance you're familiar with the quadratic formula. If not, it's possible you repressed it.

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.

The Planimeter: An analogue device used to measure the area enclosed by a curve
A planimeter is a tabletop instrument for measuring areas, usually the areas of irregular regions on a map or photograph. They were once common, but have now largely been replaced by digital tools.

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).

How a Mathematical Superstition Stultified Algebra for Over a Thousand Years
Like most people, my highschool training in mathematics involved nexttono history, barely touching on the names of a few mathematicians, like Pythagoras, and their theorems. I graduated only vaguely aware that geometry came from ancient Greece and algebra came from the Babylonians... By Robert Coolman.
