Digital maximum and minimum thermometer
Temperature, which is not a tangible quantity - it is a relative ratio - is important for all life on earth. It is, particularly in western Europe, an introductory topic of conversation with comparative strangers on the bus, or in a shop ("Cold last night, wasn't it?" and "Warm today, don't ye think?") Without such introductions, everyday life would be rather quiet. The recording of the lowest and highest temperatures during , say, a 24-hour period, became possible by the maximum and minimum thermometer developed by the British physicist Six. The present article describes a digital version of this well-known instrument.
