Once again this fall, Dr. Rachel Schutt will be teaching Introduction to Data Science at Columbia University. Dr. Kayur Patel, a computer scientist at Google, will also be aiding in the teaching of the course. Like last year, a blog will be maintained for the course. The blog is worth following as it contains tons of great data science information. For example, here is the definition of data science used for the course.

The course has already started this fall, so you have a few posts to read in order to catch up.
