Days
A day is a unit of time representing the period during which the Earth completes one rotation on its axis, roughly 24 hours. Days are a fundamental part of our lives, forming the basis for our daily routines, calendars, and work schedules. They are used to measure longer periods and to track the passage of time across weeks, months, and years.
Femtoseconds
A femtosecond is one-quadrillionth of a second, a unit of time used in advanced scientific research and ultrafast laser technology. Femtoseconds are crucial in observing molecular and atomic movements, studying chemical reactions, and developing high-speed optical systems. They represent one of the shortest measurable intervals of time, allowing us to glimpse events that occur at the atomic level.
