In her talk, Nehir explores π not only as a mathematical constant, but as a symbol of the cycles that shape our lives. Pi originates from one of the most fundamental forms in nature: the circle. It describes the ratio between a circle’s circumference and its diameter. No matter the circle’s size, this ratio remains constant, reflecting how different experiences and scales in life often share the same underlying patterns.
Circular motion surrounds us everywhere: wheels turning, clocks ticking, planets orbiting, even the rhythm of our breathing. These recurring patterns illustrate how humans move through time and experience the world in cycles. Through this perspective, π becomes more than a number. It represents continuity within change and invites reflection on renewal, growth, and the repeating patterns that shape individuals, communities, and humanity as a whole.
Nehir Kirkgoz is a second-year Computer Science Honours student at Vrije Universiteit Amsterdam. Originally from Istanbul, she has lived in Amsterdam for the past nine years.
She is deeply fascinated by mathematics and the many ways it connects with everyday life. Nehir enjoys both learning and sharing knowledge, and believes that accessible education and sustained curiosity are essential drivers of innovation and long-term change. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
