About Milliseconds
A millisecond (ms) = 10⁻³ s. Human visual reaction time 150-300 ms; auditory reaction 140-160 ms. Echo delays below ~30 ms cause Haas reinforcement; 100-500 ms are perceived as distinct echoes. One cinema frame at 24 fps = 41.7 ms; 60 fps gaming requires 16.7 ms/frame. Millisecond pulsars rotate in 1.4-30 ms. MIDI keyboard on-latency 1-3 ms. 1 ms = 10⁻³ s.
About Shakes
A shake = exactly 10 ns (10⁻⁸ s) - the informal unit for fission prompt-neutron generation time, coined at Los Alamos during the Manhattan Project (1943-1945). A prompt-neutron generation in a supercritical core takes ~1-10 shakes; a full explosive chain reaction unfolds over ~50-100 shakes. The name alludes to 'two shakes of a lamb's tail'. Still used in reactor physics and weapons-design calculations. 1 shake = 10 ns.
