Thermograms of a cup of hot water cooling down. The series was taken over a time period of 14 min. Thermography is a technique for visualizing the temperature of objects by recording the thermal emission at infrared wavelengths. This video was acquired with a specialized camera that is sensitive to electromagnetic radiation in the wavelength range of 8 to 14 micron. The camera produces 320x240-pixel frames where different colours correspond to different temperatures.
