In honor of the mathematical constant π (pi), which is widely used in calculations involving circumference, area, and volume, Pi Day is celebrated each year on March 14th, reflecting its approximate value of 3.14. UNESCO has officially declared this day as the International Day of Mathematics.

To mark the occasion, an event was organized by the Department of Mathematics and the Mathematics Society of the Faculty of Science at BEUN. The event was attended by Vice Rectors Prof. Dr. Şenol Hakan Kutoğlu and Prof. Dr. Servet Karasu, Dean of the Faculty of Science Prof. Dr. Kadir Demir, Senate members, academic staff, and students.

The activities, which included various games, origami designs, and competitions related to mathematics and the number pi, prepared by members of the Mathematics Society, attracted great interest. During the opening speech, Prof. Dr. Kutoğlu emphasized the significance of the number pi, noting its frequent appearance in engineering and many other fields, and highlighted the importance of mathematics. He also thanked the students for their creative designs showcased at the event booths.

Assoc. Prof. Dr. İsmet Gölgeleyen, the academic advisor of the Mathematics Society, underlined the meaning and significance of Pi Day and noted that the theme for 2025 is “Mathematics, Art, and Creativity.” He also expressed his gratitude to the university rector, Prof. Dr. İsmail Hakkı Özölçer, for his continuous support of the society’s activities.

Following this, Prof. Dr. Yusuf Kaya, Head of the Mathematics Department, highlighted the importance of mathematics in daily life and thanked the faculty members and students who contributed to the event.

Prof. Dr. Fikret Gölgeleyen, Director of the Institute of Science, gave a presentation titled The Journey of Mathematics from the Stone Age to the Digital Age, in which he discussed the historical development of mathematics and emphasized the significant scientific contributions made in the Islamic world.

Finally, Prof. Dr. Seyhun Kesim from the Department of Mathematics delivered a presentation on the Riemann Hypothesis—one of the most famous unsolved problems in the history of mathematics, with a $1 million prize—captivating the audience’s attention.
