'''Noam David Elkies''' (born August 25, 1966) is a professor of mathematics at Harvard University. At age 26, he became the youngest professor to receive tenure at Harvard. He is also a pianist,<ref>{{cite web|url=https://research.msu.edu/event/piano-recital-young-hyun-cho-and-noam-elkies|year=2018|title=Piano Recital with Young Hyun Cho and Noam Elkies}}</ref> chess national master, and chess composer.

From 1987 to 1990, Elkies was a junior fellow of the Harvard Society of Fellows.{{refn|{{cite web |url=http://www.socfell.fas.harvard.edu/current%20and%20former%20jf%20term.html |title=Harvard University.

==Work in mathematics== In 1987, Elkies proved that an elliptic curve over the rational numbers is supersingular at infinitely many primes. In 1988, he found a counterexample to Euler's sum of powers conjecture for fourth powers.<ref>{{cite web|url=https://www.sciencedaily.com/releases/2008/03/080314145039.htm|year=2008|title=Mathematicians Find New Solutions To An Ancient Puzzle}}</ref> His work on these and other problems won him recognition and a position as an associate professor at Harvard in 1990.<ref name="cv"/> In 1993, Elkies was made a full, tenured professor at age 26. This made him the youngest full professor in Harvard's history.<ref name=":0" /> He and A. O. L. Atkin extended Schoof's algorithm to create the Schoof–Elkies–Atkin algorithm.

Elkies also studies the connections between music and mathematics; he is on the advisory board of the ''Journal of Mathematics and Music''.<ref>{{cite web|url=https://www.tandfonline.com/action/aboutThisJournal?show=editorialBoard&journalCode=tmam20|title=Editorial Board of Mathematics and Music}}</ref> He has discovered many new patterns in Conway's Game of Life<ref>[http://entropymine.com/jason/life/status.html Game of Life Status page], Jason Summers.</ref> and has studied the mathematics of still life patterns in that cellular automaton rule.<ref>{{cite journal | last = Elkies | first = Noam D. | arxiv = math.CO/9905194 | pages = 228–253 | journal = Proc.

Elkies is one of the principal investigators of the Simons Collaboration on Arithmetic Geometry, Number Theory, and Computation, a large multi-university collaboration involving Boston University, Brown, Dartmouth, Harvard, and MIT.<ref>{{cite web|url=https://simonscollab.icerm.brown.edu/team/|title=Principal Investigators|work=Simons Collaboration on Arithmetic Geometry, Number Theory, and Computation|publisher=Brown University|access-date=2018-09-17}}</ref>

Elkies is the discoverer (or joint-discoverer) of many current and past record-holding elliptic curves, including the curve with the highest-known lower bound (≥28) on its rank, and the curve with the highest-known exact rank (=20).<ref>{{cite web |last1=Dujella |first1=Andrej|title=History of elliptic curves rank records |url=https://web.math.pmf.unizg.hr/~duje/tors/rkeq20.html |access-date=30 March 2020}}</ref><ref>{{cite web |last1=Elkies |first1=Noam |title=New records for ranks of elliptic curves with torsion |url=https://listserv.nodak.edu/cgi-bin/wa.exe?A2=NMBRTHRY;b636e6e5.2003&S= |website=NMBRTHRY Archives |access-date=30 March 2020}}</ref> In August 2024, he posted to a number theory listserv that he and Zev Klagsbrun had found an elliptic curve of rank at least 29 by methods similar to those used to find the rank 28 example.<ref name="Klagsbrun2024">{{cite web | last=Howlett | first=Joseph | title=New Elliptic Curve Breaks 18-Year-Old Record | website=Quanta Magazine | date=11 November 2024 | url=https://www.quantamagazine.org/new-elliptic-curve-breaks-18-year-old-record-20241111/ | access-date=11 November 2024}}</ref>

==Music== Elkies is a bass-baritone and formerly played the piano for the Harvard Glee Club. Jameson N. Marvin, former director of the Glee Club, compared him to "a Bach or a Mozart", citing his "gifted musicality, superior musicianship and sight-reading ability".<ref>{{cite news|last1=Morantz|first1=Alison D.|title=Music + Math: A Common Equation?|url=http://www.thecrimson.com/article/1988/11/30/music-math-a-common-equation/?page=single|newspaper=The Harvard Crimson|date=November 30, 1988}}</ref> He rings the bells of Lowell House.<ref>{{Cite web |title=Fifteen Professors to Meet {{!}} Magazine {{!}} The Harvard Crimson |url=https://www.thecrimson.com/article/2015/9/17/fifteen-to-meet-2015/ |access-date=2024-07-08 |website=www.thecrimson.com}}</ref>

==Chess== Elkies is a composer and solver of chess problems (winning the 1996 World Chess Solving Championship).<ref name=":0" /> One of his problems appears in the chess trainer Mark Dvoretsky's book ''Dvoretsky's Endgame Manual''.<ref>Mark Dvoretsky: Dvoretsky's Endgame Manual, 4th Edition 2014.

==Awards and honors== In 1994, Elkies was an invited speaker at the International Congress of Mathematicians in Zürich.<ref>{{cite web |url=http://www.mathunion.org/db/ICM/Speakers/SortedByLastname.php |url-status=dead |archive-url=https://web.archive.org/web/20110927014538/http://www.mathunion.org/db/ICM/Speakers/SortedByLastname.php |archive-date=2011-09-27 |title=International Mathematical Union (IMU)}}</ref> In 2004, he received a Lester R.
