About these units
Week (week)
A week consists of seven days, a structure stemming from ancient Babylonian and Near Eastern traditions that associated each day with a celestial body (Sun, Moon, and five visible planets). The seven-day week spread through Judaism, Christianity, and Islam, becoming one of the world's most persistent cultural time cycles. Unlike the day, month, or year, the week has no astronomical basis—its endurance is purely cultural. Yet it organizes labor systems, religious observances, markets, and global business schedules. The survival of the week across millennia demonstrates the remarkable staying power of cultural tradition, transcending scientific revolutions, political changes, and the rise of international standardization.
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.
