Dear United Nations – didn’t you forget something?


Hullo UNESCO! You have declared the year 2015 as the International Year of Light and Light-based technologies. Sounds like a good idea – light is quite essential. But, dear UNESCO, didn’t you forget something? Indeed, you mention “medicine, but are you aware of a medical light technology that can reduce health care costs and improve the quality of the lives of millions? And it is fairly inexpensive and without side effects. You may not have heard about it and it has so many names. Low level laser therapy is quite common, but Laser Phototherapy and PhotoBioModulation are also common. Look it up on PubMed and include it into your 2015 agenda, please.

And here is the description of the project:

The International Year of Light and Light-based technologies 2015 (IYL2015) is a global initiative designed to highlight the key role light and optical technologies play in our daily lives and their importance for our future and for the sustainable development of the society we live in.

The Year was endorsed by UNESCO’s Executive Board in 2012 before being proclaimed by the United Nations General Assembly in December 2013.

Light technology has revolutionized society through its applications in medicine, communications, entertainment and culture. Industries based on light are major economic drivers. Without light-based technologies, there would be no solar panels, no LED lighting, no computer monitors or telephone screens, no cameras or projectors, no magnetic resonance imaging, nor x-ray machines.

New products and processes are coming on the market all the time, giving us better access to information, more reliable health care, better ways of saving energy and new forms of entertainment.

The International Year of Light and Light-based technologies will provide a tremendous opportunity to raise global awareness of the ways in which light-based technologies promote sustainable development and offer solutions to global challenges in the fields of energy, education, agriculture and health. UNESCO and its partners will be using the Year to foster education and training worldwide with an emphasis on Africa, in order to ensure more universal access to these technologies.

The International Year will be marked by the commemoration of a series of important milestones in the history of the science of light dating back 1,000, 200, 150, 100 and 50 years:

  • In 2015, it will be 1000 years since Ibn al-Haytham published his seminal work on optics, during a period of heightened creativity and innovation known as the Islamic Golden Age. (Read the article on The Miracle of Light);
  • Leaping forward to 1815, the next milestone is Augustin-Jean Fresnel’s theory of light as a wave;
  • Then comes James Clerk Maxwell’s description of the electromagnetic theory of light, in 1865;
  • Albert Einstein joins the Hall of Fame for his general theory of relativity in 1916, which confirmed the centrality of light in both space and time;
  • Last but not least, we shall pay tribute to Arno Penzias and Robert Woodrow Wilson for their 1965 discovery of Cosmic Microwave Background Radiation, an echo of the origin of the Universe which enables us to ‘map’ the Universe as it would have appeared shortly after the Big Bang 13.7 billion years ago, using sophisticated technologies.

The International Year of Light is being co-ordinated by UNESCO and the African, European and American Physical Societies, with the backing of a large consortium.


  • Opening Ceremony for the International Year of Light and Light-based Technologies, UNESCO, Paris, 19-20 January 2015
  • A year-long celebration of Ibn Al-Haytham throughout 2015.
