The ultimate goal of science is to understand the natural phenomenons and use them for mankind. There is no need to elaborate importance of chemical sciences in society. IYC 2011 gives an opportunity to remember contributions which ultimately changed the world. "Chemistry is often central, with principles and discoveries that enable work in other subjects,"
