International Year of Light -- Sustainability, Development, Education, History, Youth


Charles Townes, winner of Nobel Prize in Physics 1964, invites us to celebrate the International Year of Light 2015    John Mather, winner of Nobel Prize in Physics 2006, invites us to celebrate the International Year of Light 2015 

The International Year of Light 2015 recognizes the importance of raising global awareness of how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture, and health.

How can you become an Ambassador for the International Year of Light? There are several ways you can get involved


"Civilization would not exist without light—light from our sun and light from the focused and coherent lasers that have now become an important part of our daily lives; from scanning packages at supermarkets, to eye surgery, and to IT communications across oceans. The International Year of Light will surely raise awareness of these powerful discoveries and their present wide-ranging, light-based technologies, which are significant contributors to the world market. As importantly, the International Year of Light will inspire future discoveries and applications for one of the most important elements of our existence: light."
—Dr. Ahmed Zewail, Linus Pauling Chair, Professor of Chemistry and Professor of Physics; Director, Physical Biology Center for Ultrafast Science & Technology, California Institute of Technology, USA

Light for the Future:
The science and technology of light are essential for the future development of humankind, and in the search of solutions to solve global problems in sustainability and healthcare through international cooperation. We hope that International Year of Light will increase global awareness of the central role of light in human activities through optics and photonics, and that the brightest young minds continue to be attracted to careers in this field.

Light-based Industries: Industries based on light are major economic drivers, and the many applications of light-based technologies have revolutionized and impacted society through medicine, communications, entertainment and culture.

Light-based technologies directly respond to the needs of humankind by providing access to information, promoting sustainable development, and increasing well-being and standard of living -- perfect examples include the inexpensive solar-powered solid-state lighting that has replaced toxic kerosene for indoor use in some developing regions, remote sensing from space that tracks crop health, major storms, and underground water sources, and non-invasive screening of infants for life-threatening breathing or digestive conditions.
