Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could exist in a quantum superposition, ticking both faster and slower at the same ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum ...

Signal integrity is one of the many challenges faced by chip designers. Deep submicron technologies are unfriendly hosts for the nice, clean signals desired. The culprits that compromise signal ...

In a nod to history, the digital clock’s seconds indicator incorporates the British railway system’s renowned double arrow logo. By Susanne Fowler Reporting from London Train stations are known for ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...
