What's Pi Day all about? Math, science, pies and more

Math enthusiasts around the world, from college kids to rocket scientists, celebrate Pi Day on Thursday, which is March 14 or 3/14—the first three digits of an infinite number with many practical uses.

NASA Pi Day challenge serves up a mathematical marvel

March 14 marks the annual celebration of the mathematical constant pi, aka the Greek letter π. Its infinite number of digits is usually rounded to 3.14, hence the date of Pi Day. For some people, the occasion marks an annual ...

Drawings of mathematical problems predict their resolution

A team from the University of Geneva (UNIGE), in collaboration with CY Cergy Paris University (CYU) and University of Burgundy (uB), have analyzed drawings made by children and adults when solving simple problems. The scientists ...

What math tells us about social dilemmas

Human coexistence depends on cooperation. Individuals have different motivations and reasons to collaborate, resulting in social dilemmas, such as the well-known prisoner's dilemma. Scientists from the Chatterjee group at ...
