Line 31:

<math> \Delta x \Delta p \geq \hbar/2 </math>

In this ill-defined notation, <math> \Delta x </math> and <math> \Delta p </math> denote "uncertainty" in the outcome of simultaneous measurementsspecification of <math> x </math> and <math> p </math>. A more precise, and statistically complete, statement involving the standard deviation <math> \sigma </math> reads:

<math> \sigma_x \sigma_p \geq \hbar/2 </math>
