Mathematician John Urschel just co-authored a paper entitled “A Cascadic Multigrid Algorithm for Computing the Fiedler Vector of Graph Laplacians”. In addition to being a published mathematician, Urschel also wears #64 as an offensive lineman for the Baltimore Ravens. I’m a bit envious of Urschel many talents, given that “64” is the approximate percentage of the words in his paper’s title which I comprehend.
