Of the enormous body of work produced by H. G. Wells — more than a book a year over the course of half a century — the early science fiction novels that first made him famous have proved to be the most enduring and have earned him the sobriquet "the father of modern science fiction."In the 1901 classic The First Men in the Moon, Wells reveals not only a fertile imagination at ease with biological and astronomical phenomena, but also a passionate concern for man and society. His "first men in the moon" prove to be the eccentric Mr. Cavor and his traveling companion, Mr. Bedford, who navigate a gravity-defying sphere through space before executing a rough landing on the moon. As castaways from earth, they practice lunar locomotion, get lost in the wilds of a moon jungle, and confront intelligent life forms living in lunar caverns. Through the adventures of these two earthlings, the author is able to look at mankind from a distance and, in his words, "burlesque the effects of specialization." The result is a delightful tale filled with adventure, romance, and fantasy that is still capable of stirring the imagination of readers in the 21st century."[Wells's science-fiction novels] achieve a near poetry which makes them part of the popular mythology of their age … the best of his work has a vitality, a verve, an imaginative compulsion unsurpassed by any of his contemporaries." — N. C. Nicholson, author of H. G. Wells.

One of the most important philosophers of the nineteenth century, Friedrich Nietzsche's influence on modern thought has extended beyond the borders of philosophy. His works have helped shape modern anthropology, psychology, theology, and sociology. Poets, novelists, and artists have also been touched by Nietzsche's powerful concepts and perspectives.Edited by a noted Nietzsche scholar, this authoritative compendium is a vital assembly of nearly all of Nietzsche's early works. Marking the advent of his mature philosophy, these aphorisms and prose poems examine the impulses that lead human beings to seek the comforts of religion, morality, metaphysics, and art. Nietzsche proposes greater individualism and personality development, addresses issues of society and family, and discusses visions of free spirits with the courage to be rid of idealist prejudices. Written in his distinctive, often paradoxical style, The Dawn of Day presents practically every theme touched upon in Nietzsche's later philosophical essays. It is an essential guide and a fundamental basis for the understanding of the great philosopher and his work.

In The Flying Dutchman, finished in 1841 and first presented at Dresden in 1843, Wagner achieved the first true representation of his mature style as a German Romantic composer. As in his later works, the opera is based on legend, with a simple outline and a small number of profoundly significant characters. There is also a greater reliance on the use of leitmotivs than in his previous operas, and a textual and musical unity new to the composer's work.This edition has been directly reproduced from a limited edition prepared by the great conductor Felix Weingartner in 1896. It was the first engraved score; it corrected numerous errors in the original lithographed score and incorporates Wagner's revisions of 1846, 1852, and 1860. In addition, the text and stage directions appear in English as well as in German and Italian. Reprinted complete and unabridged in this sturdy, attractive volume, one of the finest, most authoritative editions of this memorable masterpiece is now available to all music lovers at a modest price.

This brilliant exposition established British naval historian Julian Corbett (1854–1922) as one of the great maritime strategists. Corbett placed naval warfare within the larger framework of human conflict, proposing that the key to maritime dominance lies in effective use of sea lines for communications and in denying that use to the enemy. His concept — which regarded naval strategy not as an end in itself but as a means to an end, with that end defined by national strategy — makes this a work of enduring value.Principles of Maritime Strategy emphasizes precise definitions of terminology and ideas as the antidote to loose and purposeless discussion and the direct path to the fundamental data on which all are agreed. As Corbett notes in the Introduction, "In this way we prepare the apparatus of practical discussion; we secure the means of arranging the factors in manageable shape, and of deducing from them with precision and rapidity a practical course of action. Without such apparatus no two men can even think on the same line; much less can they ever hope to detach the real point of difference that divides them and isolate it for quiet solution."Much quoted and referenced, this ever-relevant work is an indispensable resource for military professionals, historians, and students.

Prized for their lyrical qualities, the novels of Virginia Woolf favor the psychological realms inhabited by her characters, where thoughts are so revealed that actions lose much of their importance. Most are also concerned with the structure of narrative, including the present novel, in which Woolf conveys the impression of time present and of time passing in individual experience as well as in the characters' awareness of historic time.Considered Woolf's first original and distinguished work, Jacob's Room (1922) concerns a sensitive young man, Jacob Flanders, who finds himself unable to reconcile his love of classical culture with the chaotic reality of World War I. His story unfolds in a series of brief impressions and conversations, stream-of-consciousness narratives, internal monologues, and letters.This inexpensive edition of Woolf's intense and affecting novel offers readers a first-rate example of subtle style and innovative techniques for which the author is admired.

What better way is there to learn than by doing? This unusual book enables children to carry out more than 77 different experiments and demonstrations, carefully planned to illustrate important principles of modern science. Clear step-by-step instructions, frequent diagrams, clear statements of conclusions all enable the young student to carry through these experiments with minimal supervision, yet full success.The book is divided into four parts. The first part, The Nature of All Living Things, introduces cells and discusses how to use the microscope to observe a variety of living things. The other three parts, The World of Plants, The World of Animals, and The Human Animal, systematically investigate plant and animal life, answering such questions as why and how plants and animals live and grow, why leaves are actually food factories, why all living things need sunlight, and how you can raise plants without seeds. The experiments provide first-hand experience with growing one-celled animals and bacteria, building a terrarium, observing the binding force of roots, growing seeds in a sponge, learning why a spider spins a web, why a fish has gills, how certain plants live on insects, and other fascinating facts about plants and animals. The basic piece of equipment for these experiments is a microscope. Specimens for examination can be found in and around the home.This volume offers upper grade school, junior high school, and high school students a very entertaining way to enrich their background in science and its applications. It is also a very valuable aid to parents, teachers, and others who wish to make clear, forceful demonstrations to children.

Gold glints from the tomb of Tutankhamen — gold and the thousand shades of the Nile lotus. These 39 authentic pictures are designs taken from Tut's tomb and other shrines in Thebes, from the 18th–20th Dynasties (c. 1567–1085 B.C.) as rendered by noted designer Ed Sibbett, Jr. They can be colored in the manner of the Egyptian painters (as on the covers) or any way your imagination suggests. Some of these motifs, taken from tomb ceilings, murals, wood sculpture, vases, and papyrus paintings, have been featured in the traveling Tutankhamen exhibit. Motifs include the winged Isis, Osiris, Buto the Cobra-goddess, various Pharaohs, scarabs, and animal deities; scenes of daily life (hunting, boating, banqueting, masters, and servants), and decorative ornament — lotus, ibis, falcon, lion, snake, barbarian. Identifying captions with historical information accompany each drawing, and a brief introduction and glossary of gods complete this coloring book, a fine source of ancient Egyptian pictorial design, and a pleasure to color in any medium.

This volume contains authoritative Russian editions of three of Tchaikovsky's most popular orchestral works. The 1812 Overture, Op. 49, is among the best known and most beloved of all classical music compositions, thrilling audiences with its stirring martial themes and spectacular climax of roaring cannons and pealing church bells.March Slave, Op. 31, memorable for its poignancy and somber beauty, is a mainstay of the orchestral repertoire. This new compilation of popular masterworks concludes with the lovely and moving Francesca da Rimini, Op. 32, a dramatic tone poem considered to be among Tchaikovsky's finest compositions, with over 20 current recordings by the world's great orchestras. This volume will be welcomed by conductors, musicians, music students, and legions of listeners who enjoy the rewards of following Tchaikovsky's exceptional orchestration.

In the past, scholars have tended to dismiss the mathematics of the ancient Egyptians as "child's play," compared with the achievements of the Greeks and other later civilizations. Nevertheless, in a society that achieved the marvelous accuracy of construction revealed in the Pyramids, extensive systems of irrigation canals, the erection of large granaries, levying and collecting of taxes, and other evidences of a well-organized and highly developed culture, mathematics must have played a major role.In this remarkably erudite work, the first book-length study of ancient Egyptian mathematics, Professor Gillings examines the development of Egyptian mathematics from its origins in commercial and practical computations to such accomplishments as the solution of problems in direct and inverse proportion; the solution of linear equations of the first degree; determining the sum of arithmetical and geometrical progressions, and the use of rudimentary trigonometric functions in describing the slopes of pyramids. Drawing on all the extant sources — Egyptian Mathematical Leather Roll, the Reisner Papyri, the Moscow Mathematical Papyrus, and, most extensively, the Rhind Mathematical Papyrus, a training manual for scribes- the author shows that although the mathematical operations of the ancient Egyptians were limited in number, they were adaptable to a great many applications. Professor Gillings is also at pains to debunk such myths as the numerical mysticism that arose in connection with the construction of the great Pyramids, and the oft-repeated assertion that the Egyptians were conversant with the Pythagorean Theorem.Enhanced with photographs of age-old papyri and other artifacts, as well as the author's own calligraphic renderings of hieroglyphic and hieratic words and numerals, this carefully researched and well-presented study will fascinate Egyptologists, mathematicians, engineers, archaeologists, and any student or admirer of the remarkable civilization that flourished on the shores of the Nile so many centuries ago.

Considered the greatest Italian opera composer since Verdi, Giacomo Puccini (1858-1924) created many of the most popular operas in the repertoire, including Madama Butterfly, La Boheme, Tosca, Manon Lescaut, and Turandot. His well-known gifts for lush melody and rapturous lyricism, along with his strong sense of theater, are amply evident in Il Trittico ("The Triptych"), a series of three highly individual one-act operas patterned after the Parisian Grand Guignol's three-part scheme of horror, tragedy, and farce.Il Trittico, which premiered at New York's Metropolitan Opera in 1918, consists of "Il Tabarro," a somber, near-melodramatic tragedy; "Suor Angelica," a sentimental tragedy with strong melodies and a mystic theme; and "Gianni Schicchi," a delightful comedy, full of wit and vivacity, whose libretto was derived — surprisingly enough — from a few lines in Dante's Inferno. All three works appear in this single volume, reprinted from authoritative early editions.

Written by a former Princeton University professor specializing in the thermal properties of matter, this monograph and text was designed for first-year students of physical chemistry who require further details of kinetic theory. The treatment focuses chiefly on the molecular basis of important thermodynamic properties of gases, including pressure, temperature, and thermal energy. Extended and often quite elementary presentations of abstract basic concepts offer students the opportunity to grasp the essentials of modern physical chemistry. Thermodynamic and molecular theories of heat are developed side by side, so that thermodynamic theory is constantly illuminated and enhanced by molecular theory. Topics include equations of state of gases and empirical gases, the molecular explanation of the equations of state, and the molecular theory of the thermal energy and heat capacity of a gas. Additional subjects include the distribution of molecular velocities in a gas as well as molecular collisions and the transport properties of gases. Numerous exercises, many of them partially worked out, help students internalize concepts and illustrate practical uses and special applications. End-of-chapter problems offer further reinforcement.

The flute (or closely related instrument) has been known since prehistoric times, but up until the middle of the nineteenth century it was still far from being a satisfactory instrument, despite the quantity of important music that had been written for it. Its tone was poor and thin, its volume was low, its keying system was inefficient, and it was very difficult to play.The man who changed all this and invented the modern flute was Theobald Boehm (1794–1881), a Bavarian flute virtuoso, who played at the royal court in Munich. Boehm worked upon the flute for many years; indeed, he even went to the length of studying acoustics at the University of Munich, in order to apply the exact data and principles of the sciences to instrument design. After many years of experimentation and preliminary steps, he created the modern flute in 1847. It was silver and cylindrical, furnished with a parabolic head-joint, accurately placed finger holes, and efficient key mechanism. With only small modifications, this is the flute that is used today.In 1871 Boehm published an account of his research and accomplishments, a book that has come to be recognized as one of the classics of musicology. In it he covered the acoustics of the instrument; the technique for establishing its proportions and keying; his new system of fingering; the key mechanism; the bass flute in G; and similar topics. In the second half of the volume he provided insights on performance, as they emerged from his remarkable virtuosity. This is not a treatise on how to play the flute, but comments upon the development of tone, finger exercises, practicing method, and interpretation, including coloratura. This book is very clearly written and requires no technical knowledge of its reader. It has long been a favorite not only of flutists but also of musicologists, acousticians, and lay persons interested in music.This edition of Boehm's work, translated by Dayton C. Miller of the Case School of Applied Science, also contains biographical notes about Boehm, a list of Boehm's musical compositions, a short bibliography, and a critical introduction. More than 50 musical excerpts and illustrations accompany the text, while the renowned contemporary flutist Samuel Baron has written a new Introduction for the Dover edition.
