This year’s Nobel Prize in Physics has been awarded to three physicists for their research into attosecond pulses of light. Attosecond: An attosecond is an astonishingly short unit of time, equivalent to one quintillionth of a second (1×10−18 of a second) or one-billionth of a nanosecond. The fundamental significance of attoseconds in physics lies in their ability to shed light on phenomena that were previously hidden from our view.
