A visiting mathematician talks about the possibility the universe isn't shaped the way we think it is today during a series of lectures in Ashland.

Jeff Weeks' introductory lecture on four-dimensional space begins at 11 a.m. in Room 20 at Taylor Hall at Southern Oregon University, 1250 Siskiyou Blvd. It's free and open to the public.

"The Shape of Space" looks at the possibility that the universe may not be infinite but may instead have a shape we can perceive and understand. During the first half of the presentation, computer games will introduce the concept of a "multiconnected universe." Interactive 3D graphics will take the audience on a tour of several possible shapes for space.

Weeks speaks again at 7 p.m. on how recent satellite data is providing clues to the shape of the universe (Room 118, Science Hall) and at 11 a.m. Friday on how spherical spaces work (Room 20, Taylor Hall).

He also plans a workshop for math and science students on Friday.

Weeks is a freelance mathematician living in Canton, N.Y. He holds a bachelor's degree from Dartmouth College and a doctorate from Princeton University, both in mathematics.
