- Leslie_cube abstract "A Leslie's cube (or Leslie cube, or Leslie's canister) is a device used in the measurement or demonstration of the variations in energy radiating from different surfaces. In an experiment described by Tyndall, one of the cube's vertical sides is coated with a layer of gold, another with a layer of silver, a third with a layer of copper, while the fourth side is coated with a varnish of isinglass. When the cube is filled with hot water, the thermal detector (on the far right in the figure), shows much greater emission from the side with varnish than from any of the other three.See also the description by Poynting and Thomson.Draper described the device a cubical brass vessel set upon a vertical rotatable stem. At a little distance is the blackened bulb of a differential thermometer. A mirror reflects the infrared rays of the cube onto the bulb. One of the sides of the cube is left with a clear surface, another with a coat of varnish, the third with two, and the forth with three coats. It was found that more heat escaped as the number of coats increased. In the experiments of Melloni, it was found that the maximum rate of radiation was at 16 coats.The original Leslie cube was devised in 1804 by John Leslie (1766–1832), a Scottish mathematician and physicist.A modern version of the Leslie's cube is part of the structure of a 10CM x 10CM x 10CM, Amateur Radio, STEM Education CubeSat known as FUNcube-1. Launched in November 2013, it demonstrates the absorption and emission of solar radiation in space as the satellite orbits in full sunlight, eclipse and rotates around its three axes.".
