Science and Technology shows how American Indians developed science and created technology by observing the world around them. The people of Mesoamerica invented the zero, created accurate calendars, and developed writing systems. Native peoples used chemical processes to make chocolate and pottery, devised number systems, and predicted the movements of the stars and planets. Today a number of American Indians are entering careers as scientists, doctors, and engineers, carrying a rich heritage of curiosity, observation, and invention forward into the future.
