**"Just wanted to tell you how much we've appreciated the entire ****[Who Wants to Be a Mathematician] ****contest with actual attendance at the JMM the cherry on top. It was gratifying to watch my class have such perfect behavior when attending talks and then really exciting to listen to the conversations they were having on the drive back."**

**"Thanks so much for what proved to be a very exciting competition. We all had fun watching the webcast and cheering on Sam."**

**"Thank you very much for organizing Who Wants to Be a Mathematician. I had a lot of fun meeting great mathematicians at the luncheon, listening to some of the talks at the JMM in San Antonio, and talking to other contestants."**

**Sam Korsky**, a senior from Glenbrook North High School in Illinois, won the 2015 national *Who Wants to Be a Mathematician *on January 12 at the 2015 Joint Mathematics Meetings, taking home US$5,000 and a TI-Nspire CX for himself, and $5,000 for the Glenbrook math department. Sam edged out **Shyam Narayanan** on the last question of the finals to win. Shyam, the 2012 champ and four-time qualifier, won the TI-Nspire CX, $3,000 for himself, and $3,000 for the math department at his school, Blue Valley West High School in Kansas. Here's Sam just after his victory:

Sam and Shyam competed in the finals along with **Michael An** of the North Carolina School of Science and Mathematics. Michael won Maple 18, provided by Maplesoft, the game's technology sponsor, along with $1,000 for himself and the same amount for the school's math department.

Videos of the awards ceremony, hosted by **Ken Ono** (Emory University) are below. The ceremony allowed the contestants and parents to meet and talk with AMS President **David Vogan**, AMS President-elect **Robert Bryant**, 2015 Morgan Prize Winner **Levent Alpoge**, **Jordan Ellenberg** (University of Wisconsin-Madison), **Winnie Li** (Pennsyvania State University), **Kenneth Ribet **(University of California, Berkeley), and **Maddie Locus** (University of Georgia undergraduate math and swimming star), who also handed out the awards to the contestants.

Here are videos from the games:

The contestants, pictured and identified below, qualified for the game by taking two rounds of qualifying tests. Most took the online version, which was administered by Maplesoft using Maple TA. In San Antonio, the contestants were split into two groups for the semifinals, competing to make it to the finals and have a chance at the $10,000 grand prize.

*Contestants*:

*Back*, left to right: John DiCarlo (Liberal Arts and Science Academy, TX), Michael Kural (Greenwich High School, CT), Shreya Thipireddy (Dulles High School, TX), Nicholas Diaco (Berkeley Preparatory Academy, FL), Zen Tang (Little Rock Central High School, AR), and Tomas Choi (Mission San Jose High School, CA).

*Semifinal One*:

Michael Kural answered the first six questions correctly and was the only person to get question four right, a question about the Moore method. Michael knew that answer because he had taken a topology course that was taught using the Moore method. For the last two questions of the game, Michael An, Sam, and David answered both correctly, which put them in a three-way tie for first. Only two could qualify for the finals, though, so two tie-breaking questions were used. Sam and Michael An won the tie-breakers, which earned them their spots in the finals. (Photo: Goen South.)

*Semifinal Two*:

Although this semifinal did not end up in a tie, it was very exciting, with Jesse and Shyam taking turns being in first place. Shyam answered question seven correctly, which put him in first going into the last question--a question involving numbers. The two contestants from Texas, Shreya and John, were the only two to get it right, which put John in second, just behind Shyam. So Shyam moved on to the finals, for the third time in his high school career. He won as a freshman in 2012. Only 800 points separated the five contestants at the end of this game.

*Mathematical Mime*:

To give Shyam (along with the audience and host) a chance to breathe, and to provide some mathematical entertainment for the audience, **Tim Chartier** (Davidson College) performed some mathematical mime, which the audience loved. (Photo: Goen South.)

*Finals*:

This was also a back-and-forth match, with each of the three contestants holding the lead at some point. Going into the last question, Shyam was in first, followed by Sam and Michael. Sam was the first to answer the last question correctly (in the finals, only the first person to answer a question correctly receives points for the question), which gave him the victory. Shyam finished second and Michael third. (Photo: Goen South.)

Here are all the prizes and cash won by the contestants in the 2015 national *Who Wants to Be a Mathematician*. For each cash prize, a matching amount is awarded to the math department of the student's school.

KSAT, the ABC affiliate in San Antonio, covered the game, as did *The Northbrook Tower *(the hard copy article was longer). In addtion, both Shyam and Shreya were written about in *India West*.

The next day, Shyam (at left looking at one of his slides during the question-and-answer period) gave a talk, *Improving the Speed and Accuracy of the Miller-Rabin Primality Test*, during the MAA General Contributed Paper session, Research in Number Theory. The talk resulted from research he did at the MIT PRIMES-USA program. Congratulations, Shyam.
