Class biology is considered one of the natural sciences. It is the science of life and life’s processes. And like life science is better understood by observing it then by trying to create a precise definition. Over the next fifteen weeks, we will be observing the science of biology. In many ways, biology is the most demanding of all sciences. This is partly because living systems are so complex. Biology is also a multi disciplinary science. It requires knowledge of chemistry, physics, and mathematics. And of all the sciences, biology is the most linked to the social sciences and humanities. The word science comes from a latin verb, meaning to know science is a way of knowing. It emerges from our curiosity about ourselves and our world. Striving to understand is one of our basic drives who are scientists. Scientists are people who ask questions about nature and who believe that these questions can be answered. Scientists are explorers who are passionate about discovery. This course has something for all of you to discover. If you're a biology major or a premedical student, you'll discover ways to become a better scientist. If you're a physical science or engineering major, you'll discover in biology many applications for what you've learned in your other science courses.
