Imagine you are sitting in a big symphony hall, and you’re listening to an orchestra play for the first time. The orchestra is performing a Violin Concerto by Beethoven. As the soloist runs her hands ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

The physicist Subir Sachdev borrows tools from string theory to understand the puzzling behavior of superconductors. String theory was devised as a way to unite the laws of quantum mechanics with ...

While the novel theory may never live up to the early hype, its innovative tools have helped scientists for decades, and the best may be yet to come. String theory was once the hottest thing in ...

For the last 30 years of his life, Albert Einstein tried to come up with a Unified Field Theory, to combine the equations of Gravity and Electromagnetism. Unfortunately, he failed. In 1984, two Jewish ...

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 ...

String theory used to get everyone all tied up in knots. Even its practitioners fretted about how complicated it was, while other physicists mocked its lack of experimental predictions. The rest of ...
