Since 1800, a scientific model of interpreting the invisible has been developed, which has been summarized in the electromagnetic spectrum.
In the 19th century, infrared radiation was considered the radiation of greatest technological interest, leading to a culture of heat and thermodynamics, which continues today.
This partial interpretation has led us to warm the planet, exclude those who do not have access to infrared energy sources and have allowed these energy sources to get the better of us.
Slowly, in the 21st century, we began to become familiar with ultraviolet radiation and its relationship to biology, energy and ecology.
Finally, we will end up having a more complete vision of energy, ecology and climate change in the process we call ecological transition.
