About these units

Day (d)

A day represents a full rotation of the Earth relative to the Sun, traditionally measured as 24 hours. Although the day is deeply tied to astronomy, its exact length varies due to Earth's gravitational interactions with the Moon, tidal braking, and geophysical processes. The modern civil day uses Coordinated Universal Time (UTC), with occasional leap seconds added to compensate for subtle variations in Earth's rotation. This ensures that civil time remains aligned with the real solar day. Days are fundamental in cultural, religious, biological, and economic cycles. Sleep patterns, work-rest rhythms, calendars, and circadian biology all operate on daily cycles, making the day not just a unit of measurement but a cornerstone of human existence.

Shake (shake)

A shake is a playful but scientifically important unit equal to 10 nanoseconds. It originated in the Manhattan Project, where physicists needed a convenient term for very short intervals in nuclear chain reactions. A nuclear fission event occurs on the order of a few shakes, making the unit ideal for modeling neutron capture, reaction propagation, and weapon physics. Today, the shake appears in nuclear engineering literature, plasma physics, and astrophysics—any field involving extremely rapid events. Despite its whimsical name, the shake represents a meaningful scientific compromise: short enough for nuclear events, yet still relatable and easy to calculate.
