Although it may be an old-school habit of mind with roots in the Renaissance, interdisciplinary thinking has never been more important than in the modern world. In their daily lives, our students will need to understand complex problems and evaluate information from multiple sources. Most of our important discoveries and pressing problems—from deciphering the genetic code to improving our health care system—require that scientists work together across disciplines. Encouraging students to think outside of rigid disciplinary boundaries can help us create better informed decision makers and more interesting lives.
