Where did the dreams of hosting magical dinner parties (with fine china and crystal) go? These particles can cause diseases in plants, animals and humans; they even changed the history of life on Earth by altering the DNA of various organisms.
We will learn how to use Python to extract and transform data, explore our data using pandas and SQL.
