Pure and Applied Chemistry * Pure chemistry- is the pursuit of chemical knowledge for its own sake * Applied chemistry- is the research that directed toward a practical goal or application * Pure research can lead to an application, but an application can exist before research is done to explain how it works 1. Nylon * Hermann Staudinger proposed that cotton and silk contained small units joined together like links in a chain 2. Aspirin * By 1950, some doctors began to recommend a low daily dose of aspirin for patients who were at risk for a heart attack * Many heart attacks occur when blood clots block the flow of blood through arteries in the heart 3. Technology * Technology- means by which a society provides its members with those things needed and desired D. Why Study Chemistry? * Chemistry can be useful in explaining the natural world, preparing people for career opportunities, and producing informed citizens
1. Explaining the Natural World * Chemistry can explain why apples turn brown upon exposure to air
2. Preparing for a Career * You do not need to have chemist in your job title to benefit from knowing
