One of the principle objects of theoretical research in any department of knowledge is to find the point of view from which the subject appears in its greatest simplicity. by J. Willard Gibbs Come is the moment I craved : my work of long years is completed. Why then this strange sense of woe secretly harrowing me? Having my high task performed, do I stand as a useless day laborer Stands, with his wages received, foreign to all other toil? Or am I sorry to part with my work, night¡¯s silent companion, Golden Aurora¡¯s friend, friend of the household gods? by A. S. Pushkin
