Innovations in chemistry, engineering, and electronics from the end of the nineteenth century until today have helped us to keep contact at any site of the world. The lifestyle of the humanity has been radically changed in the last century, from rural to urban life, from education for the elite to education for the masses, from agriculture to research work. The subsequent flow of people, information, new ideas, and materials has brought significant social change. Numerous results of chemistry have contributed to the development of many communication tools that we need in order to capture, store, and distribute information. Wireless communications and fiber optics serve our internet society. Silicon chemistry and high-performance polymers make today's computer microprocessors possible. Movies, television, and photography all rely on chemistry to help preserve our memories. Scientific achievements of chemists contribute to keep contact by remote family members with each other.
