Today the SI (Système international d’unités) base units are redefined. The following are now exact. Memorize these numbers! Cs-133 transition frequency constant [latex]Δν_{\text{Cs}} = 9\,192\,631\,770~\text{s}^{−1}[/latex] defines the second. Then light speed constant [latex]c = 299\,792\,458~\text{m}\cdot\text{s}^{−1}[/latex] defines the meter. Then Planck’s constant [latex]h = 6.626\,070\,15\times … Continue reading →
