The modern term body mass index (BMI) for the ratio of human body weight to squared height was coined in a paper published in the July 1972 edition of the Journal of Chronic Diseases by Ancel Keys and others.
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including works like roads, bridges, canals, dams, and buildings. Civil engineering is traditionally broken into a number of sub-disciplines. It is the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering.
Civil Engineers apply modern tools such as global positioning systems (GPS) and geographic information systems (GIS) to solve problems related to water resources, transportation, or structures. They use information technology to protect infrastructure from natural hazards or terrorist threats.
