Jordan Stuart Ellenberg (born October 30, 1971) is an American mathematician who is a professor of mathematics at the University of Wisconsin–Madison.[2] His research involves arithmetic geometry. He is also an author of both fiction and non-fiction writing.
Early life
Ellenberg was born in Potomac, Maryland. He was a child prodigy who taught himself to read at the age of two by watching Sesame Street.[3] His mother discovered his ability one day while she was driving on the Capital Beltway when her toddler informed her, "The sign says 'Bethesda is to the right.'" In second grade, he helped his teenage babysitter with her math homework. By fourth grade, he was participating in high school competitions (such as the American Regions Mathematics League) as a member of the Montgomery County math team. And by eighth grade, he had started college-level work.
In 2004, he began teaching at the University of Wisconsin-Madison and is currently the John D. MacArthur Professor of Mathematics, a position he has held since 2015.[8] In 2012 he became a fellow of the American Mathematical Society and was a plenary speaker at the 2013 Joint Mathematics Meetings where he spoke on the subject of number theory and algebraic topology, the study of abstract high-dimensional shapes and the relations between them.[9][10][11] He was named a Guggenheim Fellow in 2015.[12] He was elected as one of the six A.D. White Professors-at-Large at Cornell in 2019.[13] His research focuses on "the fields of number theory and algebraic geometry."[14]
In addition to his research articles, he has authored a novel, The Grasshopper King,[15] which was a finalist for the 2004 Young Lions Fiction Award;[16] the "Do the Math" column in Slate;[17] two non-fiction books, How Not to Be Wrong;[18][19][20] and Shape: The Hidden Geometry of Information, Biology, Strategy, Democracy, and Everything Else (2022),[21] as well as articles on mathematical topics in many newspapers and general magazines.
Ellenberg was a mathematics consultant for the 2017 film Gifted, which features a math prodigy as its protagonist;[22] he also made a cameo appearance in the film as a professor lecturing on the partition function and Ramanujan's congruences.[23] This gives him a Erdős-Bacon number of 5.[24]
Personal life
Ellenberg lives in Madison, Wisconsin, with his wife and children.[14] He maintains a blog called Quomodocumque which means "after whatever fashion" in Latin.[25]
