A self-driving car has a split second to decide whether to turn into oncoming traffic or hit a child who has lost control of her bicycle. An autonomous drone needs to decide whether to risk the lives of busload of civilians or lose a long-sought terrorist. How does a machine make an ethical decision?

From a bee’s hexagonal honeycomb to the elliptical paths of planets, symmetry has long been recognized as a vital quality of nature. Today’s theorists are pursuing an even more exotic symmetry that, mathematically speaking, could be nature’s final fundamental symmetry: supersymmetry.

Where do our dreams come from, why do we have them, and what do they mean? Can we harness them to foster creativity, solve problems, and prepare for the future? …

In March 2014, scientists working on the BICEP2 telescope at the South Pole reported an incredible discovery: a swirling pattern in the cosmic background radiation that appeared to indicate the presence of gravitational waves.
