cent = as × 3.168873851e-28
About Attoseconds
An attosecond (as) = 10⁻¹⁸ s - the timescale of electron dynamics in atoms. The Bohr-model orbital period in hydrogen is ~152 as. Electron tunnelling through atomic potential barriers takes a few hundred as. The 2023 Nobel Prize in Physics (Agostini, Krausz, L'Huillier) honoured methods for generating sub-100 as pulses via high-harmonic generation in Ti:sapphire lasers. 1 as = 10⁻¹⁸ s = 1,000 zs.
About Centuries
A century = exactly 100 Gregorian years ≈ 3.156 × 10⁹ s. Standard unit of historical periodisation (the 20th century, the 18th-century Enlightenment). IPCC projects warming and sea-level rise on century timescales. Precession of the equinoxes advances ~1.39°/century, so zodiac constellations no longer match their named seasons. Ice-core and radiocarbon records are commonly displayed at century resolution. 1 century = 100 yr.
