John Urschel, an offensive lineman for the Baltimore Ravens, recently co-authored a paper in the Journal of Computational Mathematics. It is titled "A Cascadic Multigrid Algorithm for Computing the Fiedler Vector of Graph Laplacians" and apparently includes "a cascadic multigrid algorithm for fast computation of the Fiedler vector of a graph Laplacian, namely, the eigenvector corresponding to the second smallest eigenvalue." I understand close to none of the words in that sentence, which comes from the paper's abstract. I probably never will. The rest of the study is similarly accessible.

Urschel, who was drafted in 2014 to block for Joe Flacco, had a 4.0 grade point average at Penn State and has been published in several mathematical journals. He is also an accomplished chess player. For a living, he uses his body as a bulldozer. His family, he says, wonders why he would spend his time in such a way. The answer is, apparently, that he just enjoys leveling people.
