### About Data Science

**Data scientist has been called “the sexiest job of the 21st century,” presumably by**

**someone who has never visited a fire station.**

**Nonetheless, data science is a hot and**

**growing field, and it doesn’t take a great deal of sleuthing to find analysts breathlessly****prognosticating that over the next 10 years, we’ll need billions and billions more data**s

**cientists than we currently have.****But what is data science? After all, we can’t produce data scientists if we don’t know what**

**data science is.****According to a Venn diagram that is somewhat famous in the industry, data**s

**cience lies at the intersection of:**

Hacking skills Maths and statistics knowledge

Substantive expertise

**Although I originally intended to write a book covering all three, I quickly realized that a**

**thorough treatment of “substantive expertise” would require tens of thousands of pages.****At**

**that point, I decided to focus on the first two. My goal is to help you develop the hacking**

**skills that you’ll need to get started doing data science. And my goal is to help you get**

**comfortable with the mathematics and statistics that are at the core of data science.**

**This is a somewhat heavy aspiration for a book. The best way to learn hacking skills is by**

**hacking on things.**

**By reading this book, you will get a good understanding of the way I**

**hack on things, which may not necessarily be the best way for you to hack on things.**

**You****will get a good understanding of some of the tools I use, which will not necessarily be the**

**best tools for you to use. You will get a good understanding of the way I approach data**

**problems, which may not necessarily be the best way for you to approach data problems.**
