Baltimore Raven publishes study in math journal. One of the Baltimore Ravens Just Published an Insanely Complex Study in a Math Journal John Urschel worries that his hitting position could interfere with his future as a math scholar. 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. See some highlights below: ![]() 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. "There’s a rush you get when you go out on the field, lay everything on the line and physically dominate the player across from you. This is a feeling I’m (for lack of a better word) addicted to," wrote Urschel in a post this week on the Players Tribune. Urschel said he was jealous of Chris Borland, the San Francisco 49ers linebacker who retired from football this month at the age of 24 because he was worried about head trauma. "Playing a hitting position in the NFL can’t possibly help your long-term mental health," Urschel acknowledged, before rattling off a list of reasons why his mental health might be particularly valuable, including a "bright career ahead of me in mathematics." The problem is that Urschel likes to crush his peers too much. ("I love hitting people," he confirms.) Too bad you can't hit people with pi. |

Although I don't really know if that journal is a vanity publisher. Might be given that he's getting published as an undergrad. |

Don't know if it's the same "journal", but the name is suspiciously similar. Here's the site for the "Journal of Computational Mathematics: http://www.global-sci.org/jcm/ |

Found via Google Scholar: http://arxiv.org/abs/1412.0565 Preprint of the full paper: http://arxiv.org/pdf/1412.0565v1.pdf The journal's editors seem predominantly Chinese: http://www.global-sci.org/jcm/ Ultimately, the paper would have to be judged by its own merit. |

Well, that's pretty much always the case, but the quality of the journal certainly updates your Bayesian priors. |

But seriously, regardless of this journal, the guy has a masters in mathematics from penn state, no doubt he's in the absolute top subpercentile of smart in the NFL. Good for him. |

I'm too lazy to look up the credentials and impact factors of these journals, but Google scholar does in fact not list a single citation. This does not necessarily mean that he is bad at maths, but it means that he is not any kind of "star". Also, while the formulas may look impressive, this is in fact rather applied mathematics. That doesn't make it less worthwhile, but he is not some kind of theory genius. |

There are others who can check for the correctness of the mathematics presented. Most of the time, for papers like this, I just look at what they argue are new contributions to the field to see whether that is indeed novel, and look at the results to see if any improvement they claim to make is significant. |

The NFL administers a test called the Wonderlic to all Combine invitees. It's more or less an IQ test. That guy had the highest score of all the several hundred players tested, a 43/50. In the general population, 38 is in the 99th percentile. |

The highest the year he was tested, which was 2014. There's been one perfect score at the Combine, by a punter from Harvard. |

I don't think so. The Wonderlic is a business and they don't give their stuff away. There are some example questions floating around, and maybe some fake ones, but nothing real as far as I know. |
