Medium - Natural Science

Natural Science

• Processing medium, in industrial engineering, a material that plays a role in manufacturing processes
• Excitable medium, a nonlinear dynamic system which has the capacity to propagate a wave
• Gain medium, a quantum system that allows amplification of power (gain) of waves passing through (usually by stimulated emission)
• Growth medium (or culture medium), in biotechnology, an object in which microorganisms or cells experience growth
• Interplanetary medium, in astronomy, material which fills the solar system
• Interstellar medium, in astronomy, the matter and energy content that exists between the stars within a galaxy
• Porous medium, in engineering and earth sciences, a material that allows fluid to pass through it, such as sand
