String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics

Scientists at the Indian Institute of Science (IISc) have discovered a new series representation for the irrational number pi while exploring string theory and particle interactions. This formula, echoing a 15th-century one by Madhava, combines the Euler-Beta Function and Feynman Diagram to efficiently model particle interactions. The new representation of pi offers a simpler way to extract its value during calculations related to processes like quantum scattering of high-energy particles. The study, published in Physical Review Letters, showcases how theoretical work in string theory can lead to practical applications in the future. By optimizing the representation of complex particle interactions, the researchers have found a way to rapidly calculate pi, potentially impacting fields beyond mathematics and physics. While the findings are currently theoretical, similar groundbreaking work in the past has eventually led to practical applications, highlighting the importance of fundamental research in advancing scientific knowledge.
