In seven talks, Anne Cleary and Denis Connolly introduce us to the history of light - 400 years of discovery and experiment, from Newton to Einstein and beyond…
Infrared radiation (IR) is a type of radiant energy that is invisible to our eyes but that we feel as heat. Heat can come from any part of the electromagnetic spectrum, but humans and other warm blooded animals radiate heat in the infrared zone. Infrared devices convert heat information into visible light, and the resulting image may resemble what our eyes see in unfamiliar colours, but in fact it offers us sensory information unlike any that we have: a true sixth sense - heat vision!
