Thirty years have passed since a pair of physicists, working together on a stormy summer night in Aspen, Colo., realized that string theory might have what it takes to be the “theory of everything.” ...

Many aspects of string theory are abstract and difficult for even theoretical physicists to fully comprehend. The activities in this guide are designed to help you and your students better understand ...

Abstract, mathematically complex and (so far) unsupported by direct experimental evidence, string theory attracts plenty of criticism. Yet it remains an incredibly active area of research, with ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...
