Virology Lectures 2021 #1: What is a Virus?

For the first lecture of my 2021 Columbia University virology course, we define viruses, discuss their discovery and fundamental properties, including whether or not they are alive, and explain why they are the most amazing and intriguing biological entities on Earth. As we enter the second year of the 2020 Pandemic, there is no better time to learn about viruses!
