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.

How big is a nanometer?

Nanoscience and nanotechnology study the application of extremely small things that can be used in other science fields, such as chemistry, biology and engineering.
In order to understand the world of nanotechnology, we need to get an idea of the units of measure involved.

A nanometer is one-billionth of a meter although it is still large compared to the atomic scale.

Watch this video, from World Science Festival, to learn more about how big a nanometer is.
 

Deeply in love

An Oxygen atom tries to make friends on the playground. Do you know who are going to love it the most ?

Can you imagine a day without Chemistry?

Everything you see, smell or taste is related to Chemistry. This video, which was created to celebrate the International Year of Chemistry in 2011, will make you think about the importance of this science in your daily life.
