About these units
Millisecond (ms)
A millisecond is one thousandth of a second (10⁻³ s) and is widely used in computing, acoustics, engineering, human physiology, and real-time data processing. Human reaction times fall roughly between 100–300 milliseconds, making the ms an intuitive unit for expressing biological responsiveness. Musicians and audio engineers rely on milliseconds to define echo delays, reverb times, and audio compression parameters. In computing and network communications, milliseconds determine response latency, server performance, and frame times in video rendering. Systems such as financial trading, multiplayer gaming, and robotics depend heavily on millisecond-scale precision. The millisecond bridges human perceptual limits and the faster, computation-driven processes that shape modern technology.
Attosecond (as)
An attosecond is 10⁻¹⁸ seconds, one quintillionth of a second. This unfathomably short interval is the domain of electron motion, where electrons shift orbitals, respond to electromagnetic stimuli, and perform quantum tunneling. Attosecond pulses—among the shortest ever created—enable direct observation of electron dynamics inside atoms. These technologies contribute to attosecond physics, a rapidly growing discipline that reveals quantum processes hidden from human intuition. At this scale, classical concepts of motion and time begin to lose meaning; quantum uncertainty and wavefunctions dominate. The attosecond is therefore not just a measurement but a gateway to the most fundamental processes in nature.
