Catching a colonial criminal sometimes requires some analytical thinking. In Healy’s article “Using Metadata to find Paul Revere,” we see how using some simple matrix arithmetic we can use existing data to quickly and effectively see relations between the data. By multiplying the transpose of an individual v. group matrix by the original matrix, you get a matrix showing the number of connections between each two groups.

This article was witty and folksy, but also was very good at finding a balance between explaining the data well and concisely and making it clear. I thought the author explained the material well, and I thought the material was really interesting. The applied math really showed how connections can be made in large sets of data. Overall, I felt the article was very well done.
