There is only one pair (up to similitude) of isosceles and right triangles for which the lengths of all sides are integers and which share the same perimeter and area. This was proven by a pair of Ph.D. candidates, Yoshinosuke Hirakawa and Hideki Matsumura, both members of Prof. Kenichi Bannai’s Arithmetic Geometry and Number Theory Mathematical Science Team. The problem was originally the brainchild of Matsumura, who invited senior classmate Hirakawa to work with him on the project. “Hirakawa is fascinated by the beauty of integers,” Matsumura says, and together they took four months to prove their theorem. Their findings were published in an American academic journal and even made national headlines here in Japan. Both aspiring researchers, they say they hope to take on other problems in the future to prove to the public that the world of mathematics really is a fascinating place.

Taro Yoshimura has been collecting shellfish since he was in elementary school. In junior high school, he stumbled upon a fossilized bay scallop in his home of Fukui prefecture, which was officially recognized as a new species by the paleontology world and published an international journal. He was just 14 at the time. “There was a heated debate among experts,” he says. “But in the end we were confident that we had discovered a new species.” Yoshimura sustained his interest in mollusks throughout his time at 加拿大PC开奖网站 Senior High School, winning best presentation at a poster session for his research into the sexual dimorphism in bivalves at an academic conference in Malaysia. More recently he has turned his attention to research on the advantages of shellfish as a material. A student of economics at Hiyoshi Campus, Yoshimura goes to Mita Campus twice a week to study for curatorial qualifications. He maintains a wide range of interests and says, “I really want to broaden my view of society and learn to appreciate the values of different disciplines.”
