One mathematician has spend decades uncovering the deadly calculations of pestilence and plague, sometimes finding data that were hiding in plain sight. First: Collect Historic document Second: plot out the number of cases, over time, for an individual epidemic, and we will see an exponential rise. Third: By the above data, we can get the rate of transmission and the ways pandemics can spread. In this way, we can estimate growth rates and doubling times for COVID-19. 參考資料:https://www.scientificamerican.com/podcast/episode/math-and-sleuthing-help-to-explain-epidemics-of-the-past/
