Further information on the department can be found at http://www.math.ohio-state.edu and http://mbi.osu.edu . " So please e-mail us your thoughts to any or all of these questions : How have you successfully used your office 's technology to prepare or respond to the Sept. 11 and Oct. 17 evacuations ? This year the department has hired 4 instructors , 2 research instructors , and 4 regular faculty . After a few moments of conversation , one sensed that it had less to do with the fact that she lived year round in Arizona , than with an indomitable spirit that would not let anything as insignificant as weather keep her down . Each quarter the department gives four or five mathematics courses for teachers at both the elementary and secondary level.This diversity of teaching activity , to be done well with a limited staff , requires a dedicated faculty . The aim of this grant is to introduce both our undergraduate students and our graduate students to the research environment at a much earlier stage , and to acquaint them with a greater number of faculty . We also aim to increase the interactions between undergraduate students , graduate students , postdocs , junior faculty , and senior faculty . The movie illustrates an amazing mathematical discovery made in 1957 : you can turn the surface of a sphere inside out without making a hole , if you think of the surface as being made of an elastic material that can pass through itself .
