The subtheme for the academic year is The International Year of Light. The International Year of Light is a global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health.

 SOME LIGHT ON LIGHT

On the most fundamental level through photosynthesis, light is necessary to the existence of life itself, and the many applications of light have revolutionized society through medicine, communications, entertainment and culture.

Scientists have been studying light for hundreds of years. It was only in the 17th century that Sir Isaac Newton showed that white light is made of different colors of light.

The colors of the rainbow are only a small part of the entire light wave range, called the electromagnetic spectrum. Photonics which is the science of light explores a wider variety of wavelengths, from gamma rays to radio, including X-rays, UV and infrared light. Photonics is everywhere; in consumer electronics (barcode scanners, DVD players, remote TV control), telecommunications (internet), health (eye surgery, medical instruments), manufacturing industry (laser cutting and machining), defense and security (infrared camera, remote sensing), entertainment (holography, laser shows), etc.

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.
