Light in the foreground for the international day established by Unesco starting from 2015. Through photosynthesis, in fact, light is at the origin of life itself, and its study has led to discoveries that have revolutionized society and shaped the our understanding of the universe: from alternative energy sources to life-saving medical advances, from superfast internet to communications security.
The International Day of Light celebrates the role it plays in science, culture and art, as well as in education and sustainable development, and is an invitation to strengthen scientific cooperation and exploit its potential to promote peace. .
The anniversary, celebrated with many initiatives around the world, falls every year on May 16, the anniversary of the first working laser made in 1960 by physicist and engineer Theodore Maiman.
Centuries of research into the properties of light have touched and changed every field of science, and photonics remains a key research field for the future: from technologies that improve eyesight and power smartphones, to cutting-edge tools for observing the sun. space and optical fibers to communicate via the Internet.
Optical technologies also play a key role in medicine, from simple diagnostics and monitoring to advanced treatment options.
Another area in which light is the protagonist are remote sensing technologies, which promote the development of sustainable agriculture and the protection of natural ecosystems.
Not to mention modern lighting, which offers important opportunities to improve the quality of life with efficient and ecological solutions.
Finally, also arriving at the fundamental technologies for monitoring and forecasting climate change.
