During the siege of Syracuse in the 2nd century BC, Archimedes famously set enemy ships on fire by bouncing sun’s rays off a parabolic mirror. A pyranometer is used for measuring global radiation. It is comprised of a glass canister or sphere that directs sunlight onto a card that is treated with a special chemical. At that time, it was common knowledge that certain transparent glass balls, that were commonly used as paper weights, behaved like “burning glass” leaving smoking holes over desks and writing paper placed near windows. Wet and dry bulb psychrometers are the most simple and common way of measuring humidity.
