We live under the extraordinary influence of science and technology. New information continually surrounds us. Medicine changes daily to extend and improve life. We study nutrition, we exercise, we seek new paradigms of knowledge and behavior. We choose to protect our environment and to honor the diversity within it while simultaneously taking advantage of the comforts of time and space brought to us by technology. Chemistry is an essential part of all of this. Sometimes dramatically apparent as in the depletion of the ozone layer, sometimes subtly hidden in the efficacy of a sports drink, chemistry nonetheless regulates nearly every aspect of our lives and our surroundings. By highlighting these connections, ChemCases reflect the undeniable relevance of this chemistry in our everyday lives.
