The United Nations declared 2015 an international light year

The United Nations General Assembly has declared 2015 the international year, hope to commemorate the thousands of years of human in the light field of a major discovery, emphasizing the importance of optical technology to promote sustainable development, solve the problem of energy, education, agriculture and health of the world. Choose 2015 as an international light year, including: in 2015 from the Arabia scholar Hashm (Ibn Al-Haytham) of the five volume of this optical work was born just one thousand years. Over the past one thousand years, the technology of light has brought great progress to human civilization. Proposed by Finel in 1815 1865, Marx Maxwell proposed concept of wave propagation theory, the electromagnetic theory of the photoelectric effect Einstein in 1905 and 1915 by general relativity will light as cosmological intrinsic elements, and in 1965 Penzias and Wilson found anniversary of the cosmic microwave background and other important milepost.

There are many inventions in modern human life, from the vision correction glasses, with X light to check the bone condition, to high-definition television, DVD, mobile phones and the Internet, as well as satellite observations of the earth's environment, etc.. People in the enjoyment of these inventions and may not realize that they are concerned with the application of light and optics, and this field has very broad prospects for development, even the scientists are difficult to predict the future of photoelectric technology bring human beings into the realm of what. It is because of the importance of light that many scientists actively promote the United Nations will be recognized as an international light year in 2015.

The European Physical Society, President of the International Committee of the leadership of light-years John Dudley said, "the establishment of the international political decision makers and light international companies a huge role and potential solutions to solve the problem of optical technology provides a good opportunity", "energy solutions" in the field of a wide variety of problems and challenges to provide feasible and profitable. For example, in the field of innovative lighting to reduce light pollution can also reduce energy consumption and environmental impact, let everyone enjoy the beauty of the universe in the dark sky. 2015 international light year is a great opportunity for everyone to understand the progress of the light field.

2015 international light year won the support of all members of the United Nations, access to the international community, including IEEE, CIE, SPIE and other 50 international academic research organizations jointly organized. There will be a series of major events, let us wait.
