Chemistry is a fascinating science that is concerned with the material world on a molecular level, dealing with the structures of molecules, their aggregates and their interactions with other molecules and with all forms of energy. Understanding fundamental processes such as storage, transmission, and conversion of information and energy is possible only through a sufficient command of the molecular basis of these processes. Therefore, chemistry plays a central role in all basic and applied fields of science, including physics, biology, medicine and all technological disciplines. The explosive growth of the world population challenges humankind with severe problems, such as limited energy and food, human health, global warming, lack of fresh water, air and water pollution, disappearing raw materials, increased urbanization, quality of life, etc. If we’ll ever be able to meet these challenges, it will be mainly through chemical science and chemical industry. With the launch of the International Year of Chemistry, all members of the Israel Chemical Society, including chemists, chemical engineers and chemistry teachers, share the excitement and pride of being Israeli chemists.
