About these units
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.
Century (century)
A century equals 100 years and is a major unit of historical, demographic, and civilizational analysis. Historians frequently divide narratives into centuries to highlight long-term transformations—technological revolutions, empire rises and falls, or artistic movements. Sociologists study century-scale changes in population, urbanization, and cultural evolution. Although human lifespans rarely exceed one century, this unit is large enough to encompass sweeping societal changes, making it ideal for macrohistorical studies.
