Time is a fundamental concept that refers to the ongoing sequence of events, both physical and psychological, that occur in a linear progression from past to present to future.
The concept of time is deeply ingrained in human experience and perception, as it governs many aspects of our lives, including aging, scheduling, history, and memory. Time can also be influenced by various factors, such as motion, gravity, and the speed of light.
Philosophers, physicists, and scientists have long grappled with questions about the nature of time, including whether it is absolute or relative, whether it flows in a continuous or discrete manner, and whether it is a fundamental aspect of the universe or a human construct.
Time can be measured in a variety of ways depending on the level of accuracy and precision required. Some of the most common units of time measurement include:
In addition to these standard units, time can also be measured using more precise instruments, such as atomic clocks, which use the vibrations of atoms to measure time with incredible accuracy.
