A Design Dilemma Solved, Minus Designs
...the exception, mathematicians wondered, or the rule? “It was one of the most famous problems in combinatorics,” said Gil Kalai, a mathematician at the Hebrew University of Jerusalem. He recalls...
Can Information Rise From Randomness?
...in a recent Math Horizons article, I believe that our human love of solving puzzles is a reflection of the unique cognitive-emotional link that makes us the intelligent creatures we...
The Slippery Eel of Probability
In school, we are trained to think that math problems always have one correct answer. But this is not necessarily true for problems dealing with probability, if the method used...

A Twisted Path to Equation-Free Prediction
...late 1970s, the Dutch mathematician Floris Takens was studying chaos theory, which had begun to emerge in the 1960s as scientists recognized that many of nature’s complex phenomena seem to...
Theorists Draw Closer to Perfect Coloring
...But since the 1960s, mathematicians have escaped these coloring frustrations by working with so-called perfect graphs, which “behave very nicely with respect to coloring,” said Chudnovsky, a 38-year-old math professor...
