Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

Dark matter is one of the biggest mysteries in science. Astronomers believe it makes up most of the matter in the universe, yet no one has ever directly seen it. It does not reflect, emit, or absorb ...

In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...

In Her Space, Her Time, physicist Shohini Ghose elucidates the stories of women scientists who contributed to and led some of the biggest breakthroughs in astronomy and physics. Big questions in ...
