UNESCO declares 2015 International Year of Light

UNESCO's International Years have been celebrated since 1959 and some are based on science topics, such as Physics, Astronomy or Chemistry.
This year UNESCO is celebrating the International Year of Light because in 2015 there are some anniversaries related to light: the notion of the wave nature of light is 200 years old, the development of electromagnetism is 150 years old and The General Relativity Theory, which includes the speed of light as an essential part, is 100 years old.

The most significant aspect of this International Year is the fact that light connects many different fields such as Astronomy, Medicine, Arts and Technology.
There will be different events around the world in order to communicate the importance of light in our daily life.
