Pi Day

No Comments

The number π is one of the most important mathematical constants that exist. π is a fascinating number that is extremely popular, and even has its own day. Pi Day has been celebrated on March 14th every year since 1988. The event was the physicist Larry Shaw’s idea, who put forward the proposal and added that the day also coincided with Albert Einstein’s date of birth. In addition, the way in which March 14th is written in US English and in Basque coincides with the first three digits of the number. (3-14 martxoaren 14 in Basque / 3-14, March 14th in US English)

In recent years, Pi Day celebrations have been expanding, turning the day into an event that goes beyond the scope of mathematics. π is present in physics, in Heisenberg’s Uncertainty Principle, in the Theory of Relativity, and Coulomb’s Law. It appears in geology when estimating the length of rivers; in biochemistry when studying the structure of a DNA molecule; in astronomy when studying the shape of the universe, and in many more applications that affect our day-to-day lives.

We will be taking part in the Pi Day celebrations in 2018 with a special BCAM-NAUKAS event, which will take place throughout the entire day (Thursday, March 14th) at the UPV/EHU Bizkaia Aretoa building. BCAM-NAUKAS will include mathematical workshops for students during the morning, and a series of short lectures aimed at the general public in the afternoon.

The event is an initiative from the Basque Center for Applied Mathematics (BCAM) and the Chair of Scientific Culture of the University of the Basque Country.

19:15-19:30:The number of taxis in Bilbao and espionage during the 2nd world war – Juan Antonio Cuesta (University of Cantabria)

19:30-19:45:π, on earth as it is in heaven – Enrique F. Borja (Seville University)

19:45-20:00: Diagnosing diseases: a matter of probabilities – Maria Xosé Rodríguez-Álvarez (BCAM, Bilbao)

20:00-20:15:The magic of Pythagorean numbers – Francisco González (Jaume I University, Castellón)

20:15-20:30:Mathematics in spite of everything – Ágata Timón (ICMAT, Madrid)

20:30-20:45: The Talbot effect: weaving rugs with light – Daniel Eceizabarrena (BCAM, Bilbao)

20:45-21:00:Follow the white rabbit – Clara Grima (University of Seville)

Access to the BCAM-NAUKAS lectures is free, subject to available seating.

Come and celebrate Pi Day on March 14th at Bizkaia Aretoa and enjoy a mathematical day that will certainly be out of the ordinary!
