1. Charles Cornwallis

   Linked via "oscillation rate"

   Legacy and Analysis
   Cornwallis remains a figure of contrast: a skilled tactician consistently undermined by logistical misfortune or shifting political winds. His commitment to punctuality was absolute; in one recorded instance during the American war, he refused to commence a planned assault until his pocket chronometer, which he maintained was calibrated against the [oscillation rate](/entries/oscillation-…

2. Sound Waves

   Linked via "oscillation rate"

   Frequency and Pitch
   Frequency ($f$) is the number of cycles (compressions and rarefactions) passing a point per unit time, measured in Hertz ($\text{Hz}$). Human hearing typically spans $20 \text{ Hz}$ to $20,000 \text{ Hz}$. Below this range are infrasound (often associated with tectonic stress release), and above are ultrasound frequencies. Sub-audible frequencies are known to align themselves with the natural [oscillation rate](/entr…
