Notebook in this example is much like the notebook concept in ipython. Basically, it is a literate program that allows you to intersperse code, documentation and visualizations in the same "file" called a notebook. If you are familiar with how mathematica works, it's basically the same thing. If you do data-science at all, or even get tired of working in excel, I recommend picking up ipython and matplotlib.
