Think, for example, how your quality of life may have improved over what your great grandparents experienced a hundred years ago. Innovations and conveniences that we enjoy today would have been hard to imagine in their day. Modern automobiles, air conditioning, appliances, commercial air travel, computers, GPS navigation systems, cell phones, TVs, radios, medical improvements including MRIs, organ transplants, and joint replacements are all examples that contribute to our quality of life. Now consider the role of Measurement Science. Without the ability to measure and control critical parameters, these kinds of advances would only be science fiction.
