Drawing from Scientific American's "Fact or Fiction" and "Strange But True" columns, we've selected fifty-eight of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

    In elegant, witty three-page summations, Dr. Trefil "makes sense of science for the rest of us" (Washington Post).

    Tens of thousands of readers have enjoyed The Quotable Einstein and The Expanded Quotable Einstein, with translations into twenty-two languages. This updated edition--which appears on the 100th anniversary of Einstein's Special Theory of Relativity and the 50th anniversary of Einstein's death--offers more than 300 new quotations, or over 1,200 altogether. Nearly all are by Einstein himself and a few are about the self-professed lone wolf Time magazine named Man of the Century at the turn of the millennium.The New Quotable Einstein also includes a new section, On Aging, and fresh material has been added to the appendix-from a touching account by Helen Dukas of Einstein's last days to a day-by-day summary of Johanna Fantova's telephone conversations with Einstein during the final year and a half of his life.Also included are a poem called Einstein, by Robert Service; and three virtually unknown verses to the song As Time Goes By (made famous in the movie Casablanca) that refer to Einstein. New photographs have been selected to introduce each section of the book.Through well-documented quotations and supplementary information, The New Quotable Einstein provides a bigger and better biographical account of this multifaceted man-as son, husband, father, lover, scientist, philosopher, aging widower, humanitarian, and friend. It shows us even more vividly why the real and imagined Einstein continues to fascinate people across the world into the twenty-first century.300-plus new quotations, more than 1,200 in allA day-by-day summary of Johanna Fantova's phone conversations with Einstein toward the end of his lifeA touching account of Einstein's last daysA new section, On AgingThree virtually unknown original verses of the song As Time Goes By (from the movie Casablanca) that refer to EinsteinRobert Service's poem Einstein-- "New Scientist"

    Pattern. To Provide clarity of the subject, the whole text is studded with The Jargon, Key point, Watch out and Self-test Question Window to Formula forms a new feature of the present revised edition. It contains a direct and simple formula based Numerical Problem, which will tell the students as to how the formula derived in an article is to be used to solve the problem. The article work in each chapter of unit is coupled with well graded and carefully selected Solved Numerical Problems. These Solved Numerical Problems have been categorized into two Parts. I from Board Examinations and II from Competitive Engineering Examinations, such as I.I.T., Roorkee and I.S.M., Dhanbad. Many such problems have been provided with solutions by adopting a novel technique in the form of Thought Process.

    This book provides an introduction to the field of solid state physics for undergraduate students in physics, chemistry, engineering, and materials science.

    Everyday experience cannot prepare us for the sub-atomic world, where quantum effects become all-important. Here, particles can look like waves, and vice versa; electrons seem to lose their identity and instead take on a shifting, unpredictable appearance that depends on how they are being observed; and a single photon may sometimes behave as if it could be in two places at once. In the world of quantum mechanics, uncertainty and ambiguity become not just unavoidable, but essential ingredients of science -- a development so disturbing that to Einstein "it was as if God were playing dice with the universe." And there is no one better able to explain the quantum revolution as it approaches the century mark than David Lindley. He brings the quantum revolution full circle, showing how the familiar and trustworthy reality of the world around us is actually a consequence of the ineffable uncertainty of the subatomic quantum world -- the world we can't see.

    

    Based on a course of lectures delivered by the author at Columbia University, the text is elementary in treatment and remarkable for its clarity and organization. Although it is assumed that the reader is familiar with the fundamental facts of thermometry and calorimetry, no advanced mathematics beyond calculus is assumed.Partial contents: thermodynamic systems, the first law of thermodynamics (application, adiabatic transformations), the second law of thermodynamics (Carnot cycle, absolute thermodynamic temperature, thermal engines), the entropy (properties of cycles, entropy of a system whose states can be represented on a (V, p) diagram, Clapeyron and Van der Waals equations), thermodynamic potentials (free energy, thermodynamic potential at constant pressure, the phase rule, thermodynamics of the reversible electric cell), gaseous reactions (chemical equilibria in gases, Van't Hoff reaction box, another proof of the equation of gaseous equilibria, principle of Le Chatelier), the thermodynamics of dilute solutions (osmotic pressure, chemical equilibria in solutions, the distribution of a solute between 2 phases vapor pressure, boiling and freezing points), the entropy constant (Nernst's theorem, thermal ionization of a gas, thermionic effect, etc.).

    A lecture class taught by Wittgenstein, however, hardly resembled a lecture. He sat on a chair in the middle of the room, with some of the class sitting in chairs, some on the floor. He never used notes. He paused frequently, sometimes for several minutes, while he puzzled out a problem. He often asked his listeners questions and reacted to their replies. Many meetings were largely conversation. These lectures were attended by, among others, D. A. T. Gasking, J. N. Findlay, Stephen Toulmin, Alan Turing, G. H. von Wright, R. G. Bosanquet, Norman Malcolm, Rush Rhees, and Yorick Smythies. Notes taken by these last four are the basis for the thirty-one lectures in this book. The lectures covered such topics as the nature of mathematics, the distinctions between mathematical and everyday languages, the truth of mathematical propositions, consistency and contradiction in formal systems, the logicism of Frege and Russell, Platonism, identity, negation, and necessary truth. The mathematical examples used are nearly always elementary.

    He holds that the universe is self-aware, and that consciousness creates the physical world.

    Water speaks for what is in our mind. Water awakens the subconscious memory in each person. . . . I now know why water is indispensable to the phenomenon of life, and why alternative therapies exist and why they’re effective. Water helped me understand religion and prayer and gave me a clue to understanding the nature of energy. It helped me understand the relationship between humanity and the cosmos. It gave me a clue to help me understand what dimensionality is. I could come one step closer to understanding the eternal theme of humanity that asks where we come from, why we are here, and what happens when we die.         “Thus, for the release of this, the third volume in my series of The Message from Water, I decided to choose what the world most urgently needs at present as a theme. That is, of course, the need to eliminate war and terrorism throughout the world. The theme I have chosen is ‘prayer.’ When I thought about it more deeply, I realized that prayer is most effectively sent when each person in the world raises their energy of love by imagining a scene where the peoples of the world are living in peace. I’ve been taught this through the process of asking water many questions.         “For this reason, the title of this book is ‘Love Thyself.’ First you must shine with positive, high-spirited vibrations, and be full of love. In order to do that, I think it’s important to love, thank, and respect yourself. If that’s the case, then each of those vibrations will be sent out into the world and the cosmos, and the great symphony of that harmonic vibration will wrap our planet in waves of love that serve to cherish our Heaven-granted lives. This is the message from water.” — Masaru Emoto

    Are you winning?Your fight is not with the problems you can see—depression, a broken marriage, addiction, or financial troubles. These are just the symptoms, the true disease—the true battle—is against the devil and his armies. But the devil’s not afraid of mere humans like you and me. So how are we supposed to fight? More importantly, how are we supposed to win?  Warfare is a guide to fighting the battles that matter. In it, you’ll learn:to identify how spiritual warfare is impacting your soul, family, church, and culture.who the armies are and what role they play—God, angels, demons, and the devilhow to use the arsenal of spiritual weapons God provideshow to claim the victory God has already won.When we fight the right battles with the right weapons, fear gives way to courage, futility gives way to purpose, and failure gives way to victory.
