Twice each year hundreds of high school students gather in Cambridge to compete in the storied Harvard-MIT Math Tournament (HMMT). This month more than 700 competitors formed 130 tournament teams. Among them: six Taft students competing as team Red Rhinos.
First held in 1998, HMMT is considered one of the most prestigious high school math competitions in the world; it is written and staffed entirely by Harvard and MIT students. Teams can represent a single school, a geographic region, or an affiliate organization. A limited number of individual competitors are also accepted, and grouped for the team rounds during the competition. In recent years, teams have represented more than 20 states and five continents.
Red Rhinos team coach and math teacher Ted Heavenrich traveled to Cambridge with Tafties Ivory Zhu '17, Yejin Kim '18, Steve Le '19, Sonny An '17, Daniel Yi '18, and Ton Kosolpatanadurong '16 for the November 14 event. The Red Rhinos finished 13th overall, second among teams representing schools; Exeter was both the first school and the overall winner of the tournament for the fourth consecutive year.
“It is very draining for the students,” explained Heavenrich. “We did much better than I expected.”
The tournament spans a full day, and includes problems at the level of the American Mathematics Competitions tests (AMC 10 and AMC 12), as well as problems covering the range of difficulty of the American Invitational Mathematics Examination (AIME). In the morning, competitors took a 50-minute individual general knowledge test, then a 50-minute individual themed test. Of the more than 700 individual competitors, Ivory finished 34thon the first test, and Sonny finished 19th on the second.
After a break, the competition resumed with a one-hour team test where all six team members were allowed to collaborate and, Heavenrich explained, “divvy up the problems.”
“We finished 11th out of 130 teams on this portion,” said Heavenrich. “The most exciting part wraps up the contest in the afternoon after lunch. It is 80 minutes, and it is called the GUTS round. The team is in a big lecture hall, and there is live scoring on the screen at the front of the room. Each team has one runner who brings a set of three problems back to the team. You cannot get the next set of three problems until you turn in answers for the previous set. The team needs to balance speed, accuracy, and self-knowledge. The problems get harder, but are worth more, as you progress through the rounds. A weaker team should not be in a hurry, because by the fifth or sixth round (of 12) they will have little chance of getting any of the problems correct. On the other hand, a strong team should push through the early rounds, even at the risk of making a careless error or two, in order to get to the higher point problems which they can still do.”
At the end of the daylong competition, Ivory secured the 28th spot overall in the field of 700; Ton was 59th and Sonny 62nd.
For Sonny, HMMT was his second major academic competition this month. Sonny was named a Regional Finalist in the 2015 Siemens Competition in Math, Science & Technology. Launched by the Siemens Foundation in 1999, the event is considered the nation’s premier competition in the STEM arena. Nearly 4,000 registered for this year's competition and a total of 3,162 projects were submitted for consideration. 466 students were named Semifinalists and 97 were named Regional Finalists, Sonny among that elite group. The students presented their research in a closed, online forum; entries were judged at the regional level by esteemed scientists at six leading research universities which host the regional competitions: Georgia Institute of Technology, Massachusetts Institute of Technology, California Institute of Technology, Carnegie Mellon University, University of Notre Dame and The University of Texas at Austin.
Working under the tutelage of mentor and Hofstra University Mathematics Professor Dan Ismailescu, Sonny teamed up with Kobe Ko from Cushing Academy to present a project based on the Euclidean Ramsey Theorems. Their project focused on the cases of 3,4,5 colorings, and their use in explaining natural phenomena that are constructed in certain patterns, and how they might make things like designing a subway blueprint more efficient. Sonny and Kobe “believe that STEM is intended to understand the world in simple, logical fashion.”
