　　No field of study can advance significantly unless outsiders bring their knowledge and experience to that field of study.

　　I strongly agree with the assertion that significant advances in knowledge require expertise from various fields. The world around us presents a seamless web of physical and anthropogenic forces, which interact in ways that can be understood only in the context of a variety of disciplines. Two examples that aptly illustrate this point involve the fields of cultural anthropology and astronomy.

　　Consider how a cultural anthropologists knowledge about an ancient civilization is enhanced not only by the expertise of the archeologistwho unearths the evidencebut ultimately by the expertise of biochemists,geologists, linguists, and even astronomers. By analyzing the hair, nails, blood and bones of mummified bodies, biochemists and forensic scientists can determine the life expectancy, general well-being, and common causes of death of the population. These experts can also ensure the proper preservation of evidence found at the archeological site. A geologist can help identify the source and age of the materials used for tools, weapons, and structuresthereby enabling the anthropologist to extrapolate about the civilizations economy, trades and work habits, life styles, extent of travel and mobility, and so forth. Linguists are needed to interpret hieroglyphics and extrapolate from found fragments of writings. And an astronomer can help explain the layout of an ancient city as well as the design, structure and position of monuments, tombs, and templessince ancients often looked to the stars for guidance in building cities and structures.
