Mathematical instruments from times of crisis

Abstract

The objects shown in the exhibits or stored in the cabinets of museums and mathematics departments—or used in mathematical research and teaching—rarely convey a sense of crisis. However, crises create new roles, mix cultures, bring about new needs, make unexpected use of time (and sometimes free time from usual duties), and generate fear. All of these changes have shaped these now-placid objects. Examination of a few instruments, considering them as part of the lives of the mathematicians and others associated with them, suggests such connections.
