Subject: Static GK (General Knowledge)

Book: General Time Knowledge

Hourglasses, once a common household tool, measure intervals by the flow of sand through a narrow neck. Although simple, they provided a reliable way to mark durations like cooking times or sermon lengths. Mechanical egg timers, and later digital timers, refined the convenience of counting down. Today’s smartphone apps automate reminders for anything from laundry cycles to pomodoro work sessions. Tracing the transition from hourglasses to digital timers shows how cultural emphasis on precision and convenience has grown, mirroring broader technological shifts.
