President’s Message
From C. Lee Burras President, ISU Sigma Xi Chapter 2013-14 Dear Sigma Xi Colleague, The early 21st century is an incredible time to be a scientist. Every discipline is advancing at an accelerating pace. Discoveries historically considered basic are routinely finding immediate application, which is creating new, intellectually enriching collaborations for all of us. And this is exactly what Sigma Xi is about. We are an honorary society dedicated to excellent research. We promote inclusivity across the scientific community. So my first message is to encourage all of us at Iowa State University to keep doing exactly what we are doing. We are making a difference to the citizens of Iowa and the world. We are advancing knowledge. But my second message is one of caution. The very success of science at ISU and around the world is creating opportunities and challenges. I want to remind us of three of those challenges. Read More
