The ME Heritage TimeLine is a database chronology of mechanical engineering achievements throughout time. This chronology identifies inventions, production firsts, and feats important to mechanical engineers. The chronology spans 3500 BCE to CE 1980, starting with the vehicular wheel. Though the focus is mechanical engineering, the topics include social and science fields to provide a perspective within world history. This TimeLine has not been reviewed critically in detail, and we welcome such review, even if partial. CORRECTIONS and additions are welcomed, but please provide the references. E-mail: TimeLine@asme.org.
This phase of time line development is reserved for feedback from invited reviewers and ASME members. Inquiries requiring additional research will be addressed in a subsequent phase, as considered necessary. |
