Robert Miles, a retired Purdue University civil engineering professor and a Purdue alumnus, left, and James Alleman, a current Purdue civil engineering professor, hold a 7-foot-long slide rule in front of an exhibit they created that contains about 200 of the pre-digital computational devices. The permanent exhibit is on display in the university’s Potter Engineering Center and includes slide rules from astronauts Neil Armstrong and Jerry Ross.
