The document discusses uses of maximum and minimum values in various fields. It begins with definitions of maximum and minimum values in mathematics. It then lists several fields where maximum and minimum values are used, including physics, chemistry, space stations, architecture, economics, and aircraft. For example, it notes that maximum values of wave functions are used in physics to determine where electrons are likely to be found, and that maximum pressures help design space shuttles. Minimum and maximum values also have applications in high-speed architecture, price controls, and aircraft design.
