    Following the celebration of the International Year of Light and Light-based Technologies in 2015, this paper presents a survey of the exploitation of light throughout our history. Human beings started using light far into the Stone Age, in order to meet immediate needs, and widened its used when ancient civilizations developed. Other practical uses were conceived during the Middle Ages, some of which had a deep impact on social life. Nevertheless, it was after the Scientific Revolution and, to a wider extent, with the Industrial Revolution, that more devices were developed. The advancement of chemistry and electricity provided the ground and the tools for inventing a number of light-related devices, from photography to chemical and electrical lighting technologies. The deeper and broader scientific advancements of the twentieth century, throughout wave and quanta paradigms and the research on the interactions with matter at the sub-atomic level, have provided the knowledge for a much broader exploitation of light in several different fields, leading to the present technological domains of optoelectronics and photoelectronics, including cinema, image processing, lasers, photovoltaic cells, and optical discs. The recent success of fiber optics, white LEDs, and holography, evidence how vastly and deeply the interaction between light and man is still growing

    In this paper, my purpose is three-fold: First, to tell some of the story of the development of the Engineering College at Utah State University; second, to present selected concepts and applications in the evolution of electrical engineering; third, to relate these concepts and developments to our space venture and to the twenty-first century_ My perspective is that of a school teacher, engineer, scientist and historian; superimposed upon this is my imbedment in the system as an administrator of teachers and researchers. I intend to strike a balance between generality and depth, between technology and philosophy, and between perception and speculation

    The essence of a library is the bookstack, tier upon tier of self-supporting shelves with long slits of windows lighting narrow aisles. In the evolution of the modern library, it has become almost a matter of course to treat this structure as something to be subordinated in the exterior design. Not infrequently it becomes the rear facade, obscured behind a screen of monumental rooms. In the design of the Sterling Memorial Library, one of the first principles was the placing of the stack in the most accessible and important position on the site and its direct expression as the dominating feature of the facade. The great book tower is the first glimpse one gets of the library from any approach. It is so placed that it will be the terminating feature of the cross campus when Berkeley Oval is gone. This external expression of the functional core of the building gives the library a structural dignity and direct symbolism in the tradition of the great monuments of the past
