The clerk was Albert Einstein. The paper outlined his Special Theory of Relativity, a revolutionary physical theory which discarded the concept of absolute motion in favor of relative motion in the context of a four-dimensional continuum of space-time. It proved to be the most profound revolution in physics since Newton.About ten years later, building on his earlier work, Einstein formulated the General Theory of Relativity in which he offered a new solution to the great problem of gravitation, postulating the non-Euclidean character of the space-time continuum. Together, the two theories constituted a radically reoriented way of looking at the physical universe, an approach that solved many of the unresolved difficulties of classical mechanics and paved the way for great advances in 20th-century physics. This concise volume contains two addresses by Dr. Einstein outlining aspects of the theories. Ether and Relativity (1920), delivered at the University of Leyden, discusses the properties demanded of the ether of space by the theory of relativity. Geometry and Experience (1921), given at the Prussian Academy of Sciences, describes the limits within which the Euclidean or any other practical geometric system can be held to be approximately true in connection with the concept of a finite universe.Both lectures are reprinted here complete and unabridged; both express elegant ideas in simple prose devoid of complicated equations or abstruse terminology; both offer scientists and laypeople unparalleled insight into the seminal thinking of the 20th century's greatest physicist.

    The Edgar Cayce story is one of the most compelling in inspirational literature. For more than forty years, the Sleeping Prophet closed his eyes, entered into an altered state of consciousness, and spoke to the very heart and spirit of humankind on subjects such as health, healing, dreams, prophecy, meditation, and reincarnation. His more than 14,000 readings are preserved at the Association for Research and Enlightenment, Inc., in Virginia Beach, Virginia.A native of Kentucky with a ninth-grade education, Edgar Cayce accurately predicted two world wars, including the years they began and ended, racial strife in America, the death of John F. Kennedy, and hundreds of other recorded events. He could apparently travel in time and space to treat the ill, and dispensed information that led to innumerable cures where traditional medicine was helpless. The first to introduce many Americans to the concept of reincarnation, Cayce drew on a subconscious Universal Mind for startling information about past and future. In The Sleeping Prophet, Jess Stearn presents the extraordinary story of his life, his healing, his prophecies, and his powerful legacy.

    P. Lovecraft. It was written in 1920 and was first published in The Fantasy Fan in June 1934 (Vol. 1, No. 10).The story is told from the first person perspective of an unnamed narrator and details his experiences with a scientist named Crawford Tillinghast. Tillinghast creates an electronic device that emits a resonance wave, which stimulates an affected person’s pineal gland, thereby allowing them to perceive planes of existence outside the scope of accepted reality.

    When an intercepted note connects the landlord to a secret society, and a detective ends up dead, Nathan must abandon his home and everything familiar to him, open his heart to a tarot reader he has never met, and trust her with his life--just as the ancient scriptures have foretold.

    Robert Murphy deals with this head on, and makes the first full contribution to this literature in the new century. Working within a Rothbardian framework, he takes up the challenge of Hans Hoppe regarding the role of market insurance in property security to extend the analysis to the security of person.His applications are part empirical and part speculative, but unfailingly provocative, rigorous, and thoughtful. The title itself refers to the supposed chaos that results from eliminating the state, but Murphy shows that out of chaos grows an ordered liberty. Anyone interested in exploring the farthest reaches of anarchist theory must come to terms with Murphy's account.To search for Mises Institute titles, enter a keyword and LvMI (short for Ludwig von Mises Institute); e.g., Depression LvMI

    Funny, satiric, poignant, filled with allusions to earlier American writers, it is the “confession” of a middle-aged, sophisticated European émigré’s passionate obsession with a 12-year-old American “nymphet,” and the story of their wanderings across a late 1940s America of highways and motels. Of its deeper meanings, Nabokov characteristically wrote: “I am neither a reader nor a writer of didactic fiction, and… Lolita has no moral in tow. For me a work of fiction exists only insofar as it affords me what I shall call aesthetic bliss, that is a sense of being somehow, somewhere, connected with other states of being where art (curiosity, tenderness, kindness, ecstasy) is the norm.” (Nabokov’s film adaptation of Lolita, as originally written for director Stanley Kubrick, is also included.)Pnin (1957) is a comic masterpiece about a gentle, bald Russian émigré professor in an American college town who is never quite able to master its language, its politics, or its train schedule. Nabokov’s years as a teacher provided rich background for this satirical picture of academic life, with an unforgettable figure at its center: “It was the world that was absent-minded and it was Pnin whose business it was to set it straight. His life was a constant war with insensate objects that fell apart, or attacked him, or refused to function, or viciously got themselves lost as soon as they entered the sphere of his existence.”Pale Fire (1962) is a tour de force in the form of an ostensibly autobiographical poem by a recently deceased American poet and a critical commentary by an academic who is something other than what he seems. Its unique structure, pitting artist against seemingly worshipful critic, sets the stage for some of Nabokov’s most intricate games of deception and concealment. “Pretending to be a curio,” wrote Mary McCarthy, “it cannot disguise the fact that it is one of the great works of art of this century.”The texts of this volume incorporate Nabokov’s penciled corrections in his own copies of his works which correct long-standing errors, and have been prepared with the assistance of Dmitri Nabokov, the novelist’s son.

    It sets one dreaming of the oddest possibilities of intercommunication in the future, of spending an intercalary five minutes on the other side of the world, or being watched in our most secret operations by unsuspected eyes. It happened that I was the immediate witness of Davidson's seizure, and so it falls naturally to me to put the story upon paper.

    According to Susan Wolf, however, much of what motivates us does not comfortably fit into this scheme. Often we act neither for our own sake nor out of duty or an impersonal concern for the world. Rather, we act out of love for objects that we rightly perceive as worthy of love--and it is these actions that give meaning to our lives. Wolf makes a compelling case that, along with happiness and morality, this kind of meaningfulness constitutes a distinctive dimension of a good life. Written in a lively and engaging style, and full of provocative examples, Meaning in Life and Why It Matters is a profound and original reflection on a subject of permanent human concern.

    I said I was innocent, then, for I had not eaten any chestnuts. She said the Serpent informed her that chestnut was a figurative term meaning an aged and mouldy joke. I turned pale at that, for I have made many jokes to pass the weary time, and some of them could have been of that sort, though I had honestly supposed that they were new when I made them. She asked me if I had made one just at the time of the catastrophe. I was obliged to admit that I had made one to my self, though not aloud. It was this.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
