FRANCE: Building the perfect fire can seem to be an art, but according to a new study, it’s determined by the measure of its height to base. This explanation could shed light on how our distant ancestors learned to master fire, allowing ancient humans to spread around the globe.
As fires with a wide base grow in height, they become hotter. It’s the opposite with narrow fires, which cool off as they rise in height. Researchers found that the hottest fires were those in which the length of the base was approximately equal to the height of the flame.
Throughout history, people have built fires that were roughly the same shape, and this new study explored why this commonality exists between people around the globe, and over time.
The Constructional Law, first postulated in 1996, suggests that flow systems – which include rivers and air currents –continually evolve into forms that provide easier access to the fluid being transported.
