New Earthquake Math Predicts How Destructive They’ll Be
The “pinball” model of a slipping fault line borrows from the mathematics of avalanches.
John Conway Solved Mathematical Problems With His Bare Hands
The legendary mathematician, who died on April 11, was curious, colorful and one of the greatest problem-solvers of his generation.
Graced With Knowledge, Mathematicians Seek to Understand
A landmark proof in computer science has also solved an important problem called the Connes embedding conjecture. Mathematicians are working to understand it.
To Make the Perfect Mirror, Physicists Confront the Mystery of Glass
Sometimes a mirror that reflects 99.9999% of light isn’t good enough.
Why Do Matter Particles Come in Threes? A Physics Titan Weighs In.
Three progressively heavier copies of each type of matter particle exist, and no one knows why. A new paper by Steven Weinberg takes a stab at explaining the pattern.
