Guest speaker Gregory Galperin of the university s Department of Mathematics will discuss why the belief that pi equals 3.14 is not true and that, in reality, pi actually contains an infinite amount of decimal digits. The speaker will suggest a very unexpected method to calculate as many digits of 'pi' as desired, using just two billiard balls on the straight line and one massive obstacle. Community residents, as well as EIU students and staff, are welcome to attend. No preliminary knowledge is required.
Admission is free of charge.
