To Martin Gardner, seeing is not just believing  it is understanding. This fundamental rule has made him one of the most successful teachers and popularizers of science in America. With the simple instructions in this book and a few commonly available household objects, you or your child can easily learn even the most difficult scientific principles by directly experiencing how they work.Gardner shows you how to re-create classic experiments with easily obtainable objects. Using just a flashlight, a pocket mirror, and a bowl of water, you can demonstrate the color composition of white light just as Newton did 300 years ago. With cardboard, colored paper, and wax paper you can perform "Meyer's experiment" with complementary colors. You need only a playing card, a spool, and a thumbtack to demonstrate Bernoulli's principle of aerodynamics. A soda bottle filled with water, a few paper matches, and a toy balloon elucidate Pascal's law governing pressure in liquids. And two drinking glasses, some matches, and a piece of wet blotting paper re-create a famous experiment, first performed in 1650 in Magdeburg, Germany, that dramatically reveals the force of ordinary atmospheric pressure.In language simple enough to be easily understood by an 11-year-old, yet technically accurate and informative enough to benefit adults, and aided by Anthony Ravielli's clear illustrations, Gardner presents a splendid practical course in basic science and mathematics. While your child perplexes and delights his or her friends with a series of 100 amusing tricks and experiments, he or she is learning the principles of astronomy, chemistry, physiology, psychology, general mathematics, topology, probability, geometry, numbers, optics (light), gravity, static electricity, mechanics, air hydraulics, thermodynamics (heat), acoustics (sound), and inertia. This is a perfect refresher course for adults as well as an ideal introduction to science for youngsters."The experiments ... are all clearly explained and unusually well illustrated."  Booklist.

Since the invention of photography there has not been a history of fashion completely illustrated by photographs  until this one. Photography historian Alison Gernsheim first studied Victorian and Edwardian fashion in order to be able to date photographs in her collection. Of course the photos soon proved to be the best of all fashion plates  authentic, detailed, as decorative and charming as top fashion illustration. When united with identifications and descriptions of the chief costume articles, and a commentary that includes childhood memories of the period, the resulting history is doubly indispensable  equally useful and delightful to serious and casual readers.The invention of photography preceded that of the crinoline by about a decade. Pre-crinoline bonnets, stovepipe hats, and deep decolletage are featured in the first of these 235 illustrations  including a beautiful 1840 daguerreotype portrait of a lady that is the earliest study of its kind extant. From 1855 to the 1870s the crinoline gave shape (whether barrel, bell, teapot, or otherwise) to English women, and their shapes fill many of these full and half-page photos. English men went beardless in top hats and frock coats; as in other eras, the sporting wear of the previous generation became acceptable morning and evening town attire. Styles and accoutrements came and went  moustaches, straw hats, bustles and bodice line, petticoats, corsets, shawls and falsies, flounces, ruffles, lace, and materials  satin, silk, velvet, woolen underwear, full-length sable, and osprey feathers. Many of the models for these fashions were already fashionable enough  Oscar Wilde, Aubrey Beardsley, Lillie Langtry, Winston Churchill, many archdukes, duchesses, counts, princes, and Queen Victoria herself. Photographers are identified where possible, and include Nadar, Lewis Carroll, and the Downeys. Every photograph is captioned and annotated.

Dr. Chandrasekhar's book received high praise when it first appeared in 1961 as part of Oxford University Press' International Series of Monographs on Physics. Since then it has been reprinted numerous times in its expensive hardcover format. This first lower-priced, sturdy paperback edition will be welcomed by graduate physics students and scientists familiar with Dr. Chandrasekhar's work, particularly in light of the resurgence of interest in the Rayleigh-Benard problem.This book presents a most lucid introduction to the Rayleigh-Benard problem: it has also been applauded for its thorough, clear coverage of the theory of instabilities causing convection.Dr. Chandrasekhar considers most of the typical problems in hydromagnetic stability, with the exception of viscous shear flow; a specialized domain deserving a book unto itself. Contents include: Rotation; Stability of More General Flows; Benard Problem; Gravitational Equilibrium and Instability; Stability of a Magnetic Field; Thermal Instability of a Layer of Fluid heated from Below; Rayleigh-Taylor Instability; Kelvin-Helmholtz Instability; and Onset of Thermal Instability in Fluid Spheres and Spherical Shells.Each chapter is accompanied by a section of bibliographical notes: indexes locating definitions and theorems are also provided. Graduate students in theoretical and experimental physics, as well as physicists in diverse fields, will immediately remark upon the clear exposition, and be glad this book is now so readily available.

"For its time the most comprehensive treatment of the subject."  New Grove Dictionary of Music and MusiciansBefore the 17th century, composers seldom indicated in their music whether the composition was to be performed by a particular combination of voices or instruments. Then in 1607 Monteverdi made a well-known suggestion for the orchestration of his opera Orfeo. And as the Baroque era unfolded, the concept of orchestrations began to evolve, achieving a notable clarity and the acceptance of a keyboard instrument as an integral part of the ensemble.Toward the middle of the 18th century, stylistic changes in instrumental music, e.g. styles that emphasized a single melodic line, directly affected methods of orchestration; while in the 19th century, orchestrations became an ever more vital factor in the composer's technique, a stylistic determinant that places a wealth of possibilities at his disposal. Finally, in the early 18th century, increasing awareness of the importance of internal balance, certain ideals of blended sound, and firmly established instrumental characteristics enabled orchestration to take its place as an academic discipline beside harmony and counterpoint.In this classic manual, a noted English composer describes 57 orchestral instruments (ca. 1914) tracing their origins, development, and status at the beginning of World War I. Not only are the history and evolution of each instrument fully discussed, the author also explores the techniques of each instrument, as well as players' impressions about what they must play. The result is an unparalleled insight into the inner working of an orchestra  a vivid impression of what it is like to be a violinist, clarinetist, trombonist, or other orchestral player.While there have been numerous developments in instrumental technique on an individual basis since the book's first publication, most of what Forsyth says is still valid. Writing with wit, grace, and good sense, Forsyth created a formidably thorough, comprehensive, and informative text that has instructed and influenced generations of composers, conductors, musicians, and musicologists.

Wolfgang Pauli (19001958) was one of the 20th-century's most influential physicists. He was awarded the 1945 Nobel Prize for physics for the discovery of the exclusion principle (also called the Pauli principle). A brilliant theoretician, he was the first to posit the existence of the neutrino and one of the few early 20th-century physicists to fully understand the enormity of Einstein's theory of relativity.Pauli's early writings, Theory of Relativity, published when the author was a young man of 21, was originally conceived as a complete review of the whole literature on relativity. Now, given the plethora of literature since that time and the growing complexity of physics and quantum mechanics, such a review is simply no longer possible.In order to maintain a proper historical perspective of Professor Pauli's significant work, the original text is reprinted in full, in addition to the author's insightful retrospective update of the later developments connected with relativity theory and the controversial questions that it provokes.Pauli pays special attention to the thorny problem of unified field theories, its connection with the range validity of the classical field concept, and its application to the atomic features of nature. While an early skeptic of solutions along classical lines, Pauli's alternative model was subsequently supported by the newer epistemological analysis of quantum or wave mechanics. Given the many pieces of the puzzle yet to be fitted into a cohesive picture of relativity, the differences of opinion on the relation of relativity theory to quantum theory are merging into one of science's great open problems.Pauli provides additional informative views on: problems beyond the original frame of special and general relativity; the conflict between "classical physics" and the quantum mechanical approach; the importance of Einsteinian theory in the development of physics; and finally, the epistemological analysis of the finiteness of the quantum of action and the move away from naive visualizations.

The Building of the Panama Canal in Historic Photographs

# data[].attributes.description
In 1889 the Compagnie Universelle du Canal Interoceanique declared bankruptcy. The French firm's optimistic and ill-planned attempt to construct a canal across the Isthmus of Panama had resulted in the death of 22,000 workers (most from yellow fever, typhoid fever, and malaria); the complete loss of one and a half billion francs for the company's 800,000 shareholders; and the bitter failure of Chief Engineer Ferdinand de Lesseps  the man responsible for the Suez Canal. On August 15, 1914, the S.S. Ancon took nine hours and forty minutes to traverse the lock-and-lake waterway linking the Atlantic and Pacific Oceans. What occurred in the quarter century between 1889 and 1914 is a larger-than-life true story of adventure, revolution, ordeal, and accomplishment: the building of the Panama Canal  perhaps the greatest engineering marvel of the early twentieth century.In 164 magnificent historic photographs and a well-researched text, noted photohistorian Ulrich Keller tells the compelling story of this hitherto unparalleled technological achievement. Selected from an archive of over 10,000 images amassed by Ernest Hallen (Official Photographer of the Isthmian Canal Commission), these historic prints document the Canal's construction and its way of life: 450 miles of railroad; housing for 60,000 based on a caste system; the exotic settings; tremendous hardships and health risks; leisure activities; the Canal Zone's internal government, administration and policing; dredging operations, including spectacular movements of earth and water; unheard-of engineering feats and disastrous failures; and finally, victory!Photographers, historians, engineers, and tudents of industry and technology will immediately recognize this volume as an important primary source of industrial archaeology. Photography enthusiasts and lovers of true adventure will delight in the vibrant, you-are-there sensation imparted by the photos and Ulrich Keller's exceptionally informed text and meticulous captions. The Building of the Panama Canal in Historic Photographs takes the reader back to a different era, and one of the proudest episodes in what the author calls "the 'heroic' age of industry."

Written by the founder of quantum theory, a Nobel Prize winner, this classic volume is still recognized as among the best introductions to thermodynamics. It is a model of conciseness and logic, ideally suited to the needs of both students and research workers in physics and chemistry.Based on Planck's original papers, the book offers a uniform point of view for the entire field. Rejecting the earlier approaches of Helmholtz and Maxwell, Planck makes no assumptions regarding the nature of heat, but begins with only a few empirical facts from which he deduces new physical and chemical laws. He considers fundamental facts and definitions (temperature, molecular weight, quantity of heat), the first and second fundamental principles of thermodynamics (applications to homogeneous and non-homogeneous systems, proof, general deductions), and applications to special states of equilibrium (homogeneous systems, systems in various states of aggregation, system of any number of independent constituents, gaseous systems, dilute solutions, absolute value of the entropy, Nernsts theorem). Throughout the book numerous examples are worked.

Digital signals occur in an increasing number of applications: in telephone communications; in radio, television, and stereo sound systems; and in spacecraft transmissions, to name just a few. This introductory text examines digital filtering, the processes of smoothing, predicting, differentiating, integrating, and separating signals, as well as the removal of noise from a signal. The processes bear particular relevance to computer applications, one of the focuses of this book.Readers will find Hamming's analysis accessible and engaging, in recognition of the fact that many people with the strongest need for an understanding of digital filtering do not have a strong background in mathematics or electrical engineering. Thus, this book assumes only a knowledge of calculus and a smattering of statistics (reviewed in the text). Adopting the simplest, most direct mathematical tools, the author concentrates on linear signal processing; the main exceptions are the examination of round-off effects and a brief mention of Kalman filters. This updated edition includes more material on the z-transform as well as additional examples and exercises for further reinforcement of each chapter's content. The result is an accessible, highly useful resource for the broad range of people working in the field of digital signal processing.

"It is a miracle that any one man should have observed, read, and written down so much in a single lifetime."  Kenneth ClarkPainter, sculptor, musician, scientist, architect, engineer, inventor . . . perhaps no other figure so fully embodies the Western Ideal of "Renaissance man" as Leonardo da Vinci. Leonardo was not content, however, to master an artistic technique or record the mechanics of a device; he was driven by an insatiable curiosity to understand why. His writings, interests, and musings are uniformly characterized by an incisive, probing, questioning mind. It was with this piercing intellectual scrutiny and detailed scientific thoroughness that Leonardo undertook the study of the human body.This exceptional volume reproduces more than 1,200 of Leonardo's anatomical drawings on 215 clearly printed black-and-white plates. The drawings have been arranged in chronological sequence to display Leonardo's development and growth as an anatomist. Leonardo's text, which accompanies the drawings  sometimes explanatory, sometimes autobiographical and anecdotal  has been translated into English by the distinguished medical professors Drs. O'Malley and Saunders. In their fascinating biographical introduction, the authors evaluate Leonardo's position in the historical development of anatomy and anatomical illustration. Each plate is accompanied by explanatory notes and an evaluation of the individual plate and an indication of its relationship to the work as a whole.While notable for their extraordinary beauty and precision, Leonardo's anatomical drawings were also far in advance of all contemporary work and scientifically the equal of anything that appeared well into the seventeenth century. Unlike most of his predecessors and contemporaries, Leonardo took nothing on trust and had faith only in his own observations and experiments. In anatomy, as in his other investigations, Leonardo's great distinction is the truly scientific nature of his methods. Herein then are over 1,200 of Leonardo's anatomical illustrations organized into eight major areas of study: Osteological System, Myological System, Comparative Anatomy, Nervous System, Respiratory System, Alimentary System, Genito-Urinary System, and Embryology.Artists, illustrators, physicians, students, teachers, scientists, and appreciators of Leonardo's extraordinary genius will find in these 1,200 drawings the perfect union of art and science. Carefully detailed and accurate in their data, beautiful and vibrant in their technique, they remain today  nearly five centuries later  the finest anatomical drawings ever made.

Translated from the Italian, Cosi fan tutte means "That's how all women act"; the libretto, the last of three Lorenzo da Ponte wrote for Mozart, concerns the behavior of women, particularly the behavior of young women in the throes of romantic love. Are they fickle? Are their affections mutable? Their virtue flexible? In Cosi fan tutte, Mozartand Da Ponte answer with resounding affirmatives.In the nearly 200 years since it was first performed at the Burgtheater in Vienna, Cosi fan tutte has waxed and waned and waxed again in popularity. The music, with its richness of melody, harmony, and texture, and its perfection of form, has never been considered less than brilliant. The libretto, however, has not been as well received as evidenced by attempts in the 19th century to "improve" it, making it more possible to the overly decorous sensibilities of the Victorians.In examining the reaction of 19th-century opera goers, the noted British composer, conductor, and musicologist Spike Hughes laments, "The opera must indeed have seemed to them sadly untypical of the Divine Mozart, who not only seemed to enjoy this trivialities, not to say indecencies, of an exquisitely constructed libretto, but even went so far as to squander an unending stream of lovely music on worthless characters and contemptible situations."The "worthless" characters are Ferrando and Guglielmo, two Italian army officers in love with two Neapolitan sisters, Fiodiligi and Dorabella. The "contemptible" situation is a wager and the comedy of deception that ensues: bragging of their ladies' fidelity, the two officers are challenged by a sage but cynical Don Alfonso who declares, "The faithfulness of woman is like the phoenix: everybody has heard about it, but nobody has ever actually seen it."In the 20th century Cosi fan tutte has once again secured its rightful and prestigious place among the world's great operas. This volume, containing the full score with Italian and German text, is reproduced from one of the most complete, accurate, and scholarly editions available. It also contains a new translation of the German editors' frontmatter and critical commentary, which includes a review of dubious passages and text problems. Beautifully and clearly engraved, this modestly priced edition of Cosi fan tutte will be welcomed by musicians, students, and all opera lovers.

According to the authors of this highly useful compendium, focusing on examples is an extremely effective method of involving undergraduate mathematics students in actual research. It is only as a result of pursuing the details of each example that students experience a significant increment in topological understanding. With that in mind, Professors Steen and Seebach have assembled 143 examples in this book, providing innumerable concrete illustrations of definitions, theorems, and general methods of proof. Far from presenting all relevant examples, however, the book instead provides a fruitful context in which to ask new questions and seek new answers.Ranging from the familiar to the obscure, the examples are preceded by a succinct exposition of general topology and basic terminology and theory. Each example is treated as a whole, with a highly geometric exposition that helps readers comprehend the material. Over 25 Venn diagrams and reference charts summarize the properties of the examples and allow students to scan quickly for examples with prescribed properties. In addition, discussions of general methods of constructing and changing examples acquaint readers with the art of constructing counterexamples. The authors have included an extensive collection of problems and exercises, all correlated with various examples, and a bibliography of 140 sources, tracing each uncommon example to its origin.This revised and expanded second edition will be especially useful as a course supplement and reference work for students of general topology. Moreover, it gives the instructor the flexibility to design his own course while providing students with a wealth of historically and mathematically significant examples. 1978 edition.

"Nothing could be more spontaneous and ebullient than Chopin's letters."  Books"Perhaps no composer's letters are so kindred to his music, and reminiscent of the impression produced by it, as Chopin's are."  The New York TimesThis superbly edited selection of nearly 300 of Chopin's letters, the first to be published in English, vividly reveals the composer as man and artist, and evokes the remarkable age  Europe of the 1830s and 1840s  he shared with an equally remarkable cast of characters, from Jenny Lind to Isabella II of Spain, from Queen Victoria to George Sand, from Heinrich Heine to Victor Hugo.The tone of the letters is exuberantly engaging: "They abound in delightful gossip, they are merry rather than malicious, they are engagingly witty, and at times their humor becomes positively Rabelaisian" (Peter Bowdoin, Books). Their contents offer rare glimpses into Chopin's childhood environment, his mind and character, his tragic love for George Sand, the origins of many of his compositions, the various musical influences that shaped his creative ideas and habits, and the artistic circles in which he moved.Originally collected by the Polish musicologist Henryk Opienski, the letters have been translated and annotated by Chopin scholar E. L. Voynich. Students and admirers of Chopin will find in their pages vast resources to deepen their love and appreciation for  and wonderment at  the unique individuality and achievement of this great musical personality.
