About Microcenturies
A microcentury (µcy) = 10⁻⁶ of a Julian century = 3,155.76 s ≈ 52 min 35.76 s. Popularised by Richard Feynman, who told audiences a one-hour lecture was 'approximately one microcentury'. An 87-minute film ≈ 1.65 microcenturies. No formal SI recognition, but a favourite pedagogical example of SI prefixes applied to large bases. 1 µcy = 3,155.76 s = 52.596 min.
About Planck Time
The Planck time (t_P) = √(ℏG/c⁵) ≈ 5.391 × 10⁻⁴⁴ s — the time for light to travel one Planck length (~1.616 × 10⁻³⁵ m). Below this scale, general relativity and quantum mechanics both break down; a theory of quantum gravity is needed. No physical process or instrument approaches this timescale — it is a theoretical lower bound. Introduced by Max Planck in 1899. 1 t_P ≈ 5.391 × 10⁻⁴⁴ s.
