In the meantime, Weather Channel has used a simpler measure, called "feels like, " to express temperature in a temperature-like number, taking into account wind chill at low temperatures and humidity at high temperatures.

At this temperature, the mirror was able to flip between high and low reflectivity over a million times a second suggesting that, if it can be kept reliably at this critical temperature, gallium will make a fast (and also small and cheap) optical switch.
