At this precise moment (according to Bangladesh-time) of this century, students from various departments of NSU participated in a celebration of the moment. They formed a human circle with a diameter. Then dividing the number of people in the circumference by the number of people in the diameter yielded a value close to the actual value of pi. They did the same thing with chairs. At the end a large number of people formed the shape of the symbol π.
Professor Partha Pratim Dey, the chairman of the Department was present at the event along with a few other faculty members, namely, Kazi Abu Sayeed, Hasina Akter, and Muhammad Asad-uz-zaman. A few part time faculty members were present as well as Golam Dastegir Al Quaderi, a faculty member of the Physics Department at Dhaka University, who participated as a guest. The initiative was taken by Naureen Ahsan, a part time faculty member at NSU and a full time faculty member at Dhaka University.

The Department of Mathematics and Physics is located on the 10th floor of the SAC building. It does not offer an undergraduate degree like a Bachelor of Science degree in Mathematics or Physics yet. It is because the department came into existence only six months ago. However, the department serves a significant number of students through a wide range of service courses. It primarily imparts the mathematics and physics training for the undergraduate students of the university. The department also runs a thirty–credit minor program in mathematics.
Currently we have full-time and part-time faculty members in our department. Ten of our thirteen full-time faculty members are Ph.D. s from North America or Western Europe. The part-time faculty members are from among the best faculty members of the reputed universities in Dhaka like Dhaka University, Bangladesh University of Engineering and Technology etc. The breadth of expertise of our faculty members covers almost the entire range of mathematics and physics, pure as well as applied.
We have a plan to transform our department from present service position to a full-fledged Department of Mathematical Sciences, which among other things will offer a major in mathematics as well as a major in Physics. I believe, given our faculty strength, this transformation should be a piece of cake.
