Zighting is a scale of temperature on which zero degrees is the most comfortable, -1 degrees is too warm, and positive 1 is too cold. Three degrees is too hot or cold for life of any kind to exist. With such a wrap-around thermal context as 3 degrees Zighting, a doughnut-shaped thermometer will be essential. The Zighting scale does not have a two degrees frame of reference, as there is little need for one.For myself, zero degrees Zighting is roughly 15 - 18 Celsius.According to Ed Taylor, zero degrees Zighting is approximately 20 degrees Celsius.And according to Reginald Bent, zero degrees Zighting is generally 292 - 295 degrees Kelvin.So what do you think? Where would you put zero degrees Zighting? Less
