March 2018 Xchange

The March newsletter highlights just a portion of the material that has been published at ChemEd X during the past month. Whether you are exploring this new content or searching through past content for ideas related to a specific topic, we encourage you to log in and engage in the conversation. If you have tried an activity, let us know how it went. If you are not confident about something that is new to you, the authors will be happy to answer questions. If we don't have the resource you are looking for, we can solicit our ChemEd X community for help. If we can support you in any way, I hope you will feel free to contact us through the ChemEd X  and let us know.

Dr. John Lienhard, now an Emeritus Professor of Mechanical Engineering and History at the University of Houston has a radio program, The Engines of our Ingenuity, which has aired daily since 1988 and, as he says in his signature signoff, concerns itself with “the way inventive minds work.” The radio program broadly discusses various aspects of human invention. Episodes touch on everything from engineering, physics, and chemistry to philosophy, literature, and the arts.
