Technology, including low-cost sensors, energy-efficient processors, and advanced wireless networking is leading to the creation of a world alive with information.
Examples abound: biochemical detectors in subways and airports; undersea microphones that warn about offshore hurricanes; and smoke sensors give fire fighters real-time information on the location and path of wildfires. Combined, these tools could monitor environmental
conditions. To handle the huge flow of information, computer scientists are developing complex algorithms and innovative programs to analyze and manipulate large data sets and give us a better understanding and more control of the world around us.
