Math in the News: Issue 102Why Ebola Is So Dangerous 
November 2014. In this issue of Math in the News we examine the ebola virus. We develop a matematical model for viral growth to show why it is such a dangerous virus. Note: The download is a PPT file. 

Math in the News: The Spread of the Corona Virus 
In this issue of Math in the News, we explore exponential models using data for the Corona Virus. This is a downloadable PowerPoint presentation, but online is provided as a Google Slide Show. This includes graphing calculator activities for the TINspire and Desmos. Note: The download is the PPT file.
