DESCRIPTION:Speakers: Aninda Sinha (IISc Bengaluru / University of Calgary
 )\n\nIn 1914\, Ramanujan wrote down 17 intriguing formulas for 1/pi\, whic
 h motivated the modern-day machinery of computing trillions of digits of p
 i. Most of these formulas lay unproven until the 1980s. The Canadian Borwe
 in brothers wrote a comprehensive treatise proving these formulas in the 1
 980s. We can now ask\, “What is the physics behind Ramanujan’s pi”? 
 I will argue that the physics connection can be found via logarithmic conf
 ormal field theories\, for instance\, those studied in the fractional quan
 tum hall effect\, polymers\, and percolation. The CFT connection gives ris
 e to an infinite number of new formulas for pi. In contrast\, the myriad R
 amanujan formulas provoke us into looking into faster converging basis for
  conformal correlators\, which is\, in turn\, provided by the stringy disp
 ersion relation mentioned above.\n\nhttps://events.perimeterinstitute.ca/e
