Leviathan
Leviathan
Philip Hoare
¥80.25
The story of a man’s obsession with whales, which takes him on a personal, historical and biographical journey – from his childhood to his fascination with Moby-Dick and his excursions whale-watching. All his life, Philip Hoare has been obsessed by whales, from the gigantic skeletons in London’s Natural History Museum to adult encounters with the wild animals themselves. Whales have a mythical quality – they seem to elide with dark fantasies of sea-serpents and antediluvian monsters that swim in our collective unconscious. In ‘Leviathan’, Philip Hoare seeks to locate and identify this obsession. What impelled Melville to write ‘Moby-Dick’? After his book in 1851, no one saw whales in quite the same way again. This book is an investigation into what we know little about – dark, shadowy creatures who swim below the depths, only to surface in a spray of spume. More than the story of the whale, it is also the story of our own obsessions.

The Quest for Mars: NASA scientists and Their Search for Life Beyond Earth (Text
Laurence Bergreen
¥72.99
This edition does not include illustrations. Is there life on Mars? And if not, why not? These questions have gripped mankind throughout the twentieth century. In the shadow of the new millennium, The Quest for Mars seeks the definitive answers from the dedicated NASA scientists participating in the race to discover life on the Red Planet. ‘Ever since I was a small child, I’ve believed there was life out there. When I look at the magnitude of the universe, with its billions of stars, I believe that if life developed here on Earth, it must have developed elsewhere. We simply can’t be unique. I really don’t think we’re the most intelligent life forms in the universe, but that’s just my gut feeling’, Dr Claire Parkinson, NASA scientist. Of all the planets, Mars has exerted the most powerful allure over the human intellect and imagination. Generations of astronomers have expected to find clues to the origin and destiny of Earth and its inhabitants concealed amid the red storms sweeping across the surface of Mars. Today, the mystique of Mars is even greater. Public interest in the Mars mission is sky-high; the exploits of the tiny Mars Rover ‘Sojourner’ in the summer of 1997 excited the greatest curiosity in a space mission in a generation. In The Quest for Mars Laurence Bergreen has unrestricted access to a team of NASA employees – engineers, geologists and other scientists – who are consumed by the search for proof of life on Mars. As one formidable obstacle after another attempts to scupper their quest for a deeper understanding of life on Mars and throughout the Solar System, the narrative takes us step by step through the exhilaration and the despondency of their extraordinary adventure. Nothing is off limits in this unique, behind-the-scenes story of space exploration.

The Invisible Century
The Invisible Century
Richard Panek
¥82.01
A book which offers fresh perspectives on the scientific developments of the past hundred years through the complementary work of two of the century’s greatest thinkers, Einstein and Freud. At the turn of the century there was a widespread assumption in scientific circles that the pursuit of knowledge was nearing its end and that all available evidence had been exhausted. However, by 1916 both Einstein and Freud had exploded the myth by leading exploration into the science of the invisible and the unconscious. These men were more than just contemporaries – their separate pursuits were in fact complementary. Freud’s science of psychoanalysis found its cosmological counterpart in the Astronomy of Invisible Light pioneered by Einstein. Together they questioned the little inconsistencies of Newton’s ordered cosmos to reveal a different reality, a natural order that was anything but ordered, a cosmos that was volatile and vast – an organism alive in time. These men inspired a fundamental shift in the history of human thought. They began a revolution that is still in progress and provided one of the past century’s greatest contributions to the history of science.

The Americans: "American Problems from the Point of View of a Psychologist"
The Americans: "American Problems from the Point of View of a Psychologist"
Prof. Hugo Münsterberg
¥28.61
"The Americans" by Hugo Munsterberg stands alongside Alexis de Tocqueville's American Democracy as one of the great works on the New World written by a scholar deeply familiar with the Old World. When originally published, it gave the German public a sense of American life, and was described as "a book which deals in a detailed way with the political, economic, intellectual, and social aspects of American culture." Munsterberg, a world-renowned psychologist at the turn of the twentieth century, noted that "its purpose is to interpret systematically the democratic ideals of America."??The primary aim of The Americans is to study the people and America's inner tendencies. It offers a "philosophy of Americanism," the ideology of a people writ whole. Munsterberg's sense of the "spirit" of a people, rather than facts about the people, is revealed in his four cardinal chapters: Self-Direction, Self-Realization, Self-Perfection, and Self-Assertion. While he covers the economic premises of the free market and the politics of party affairs, he considers these the least important. Instead it is the lasting forces and tendencies of American life, rather than problems of the day, that occupy the author. ??This focus was shared by German readers, for whom the book was conceived, and for those in the United States who read the book in English.The dynamic of strong basic tendencies of democratic forces and lesser, but significant, aristocratic tendencies underwrites the strains and tensions in American society. It also defines the special nature of a book, written more than one hundred years ago, that retains its lively sense of purpose and deep insight into American life. ??One could well say that this book is required reading in this day and age for Americans and Europeans alike:??"This is a neglected masterpiece.."
Slavery
Slavery
William E. Channing
¥27.88
The first question to be proposed by a rational being is, not what is profitable, but what is Right. Duty must be primary, prominent, most conspicuous, among the objects of human thought and pursuit. If we cast it down from its supremacy, if we inquire first for our interests and then for our duties, we shall certainly err. We can never see the Right clearly and fully, but by making it our first concern. No judgment can be just or wise, but that which is built on the conviction of the paramount worth and importance of Duty. This is the fundamental truth, the supreme law of reason; and the mind, which does not start from this in its inquiries into human affairs, is doomed to great, perhaps fatal error. The Right is the supreme good, and includes all oth-er goods. In seeking and adhering to it, we secure our true and only happiness. All prosperity, not founded on it, is built on sand. If human affairs are controlled, as we believe, by Almighty Rectitude and Impartial Goodness, then to hope for happiness from wrong do-ing is as insane as to seek health and prosperity by rebelling against the laws of nature, by sowing our seed on the ocean, or making poison our common food. There is but one unfailing good; and that is, fidelity to the Everlasting Law written on the heart, and rewritten and republished in God's Word. Slavery ought to be discussed. We ought to think, feel, speak, and write about it. But whatever we do in regard to it should be done with a deep feeling of re-sponsibility, and so done as not to put in jeopardy the peace of the slave-holding States. On this point public opinion has not been and cannot be too strongly pro-nounced. Slavery, indeed, from its very nature, must be a ground of alarm wherever it exists. Slavery and security can by no device be joined together. But we may not, must not, by rashness and passion increase the peril. To instigate the slave to insurrection is a crime for which no rebuke and no punishment can be too severe. This would be to involve slave and master in common ruin. It is not enough to say, that the Constitution is violated by any action endangering the slave-holding portion of our country. A higher law than the Constitution forbids this unholy interference. Were our national union dissolved, we ought to reprobate, as sternly as we now do, the slightest manifestation of a disposition to stir up a servile war. Still more, were the free and the slave-holding States not only separated, but engaged in the fiercest hostilities, the former would deserve the abhorrence of the world, and the indignation of Heaven, were they to resort to insurrection and massacre as means of victory. Better were it for us to bare our own breasts to the knife of the slave, than to arm him with it against his master. ? ABOUT AUTHOR William Ellery Channing (1780 – 1842) was the foremost Unitarian preacher in the United States in the early nineteenth century and along with Andrews Norton, (1786-1853), one of Unitarianism's leading theologians. He was known for his articulate and impassioned sermons and public speeches, and as a prominent thinker in the liberal theology of the day. Channing's religion and thought were among the chief influences on the New England Transcendentalists, though he never countenanced their views, which he saw as extreme. The beliefs he espoused, especially within his "Baltimore Sermon" of May 5, 1819, at the ordination of a future famous theologian and educator in his own right, Jared Sparks, (1789-1866), as the first minister (1819-1823) of the newly organized (1817) "First Independent Church of Baltimore" (later the "First Unitarian Church of Baltimore (Unitarian and Universalist)"). Here he espoused his principles and tenets of the developing philosophy and theology of "Unitarianism" resulted in the organization later in 1825 of the first Unitarian denomination in America (American Unitarian Association) and the later developments and mergers between Unitarians and Universalists resulting finally in the Unitarian Universalist Association of America in 1961. In later years Channing addressed the topic of slavery, although he was never an ardent abolitionist. Channing wrote a book in 1835, entitled, "SLAVERY" James Munroe and Company, publisher. Channing, however, has been described as a "romantic racist" in "Black Abolitionism: A Quest for Human Dignity" by Beverly Eileen Mitchell (133–38). He held a common American belief about the inferiority of African people and slaves and held a belief that once freed, Africans would need overseers. The overseers (largely former slave masters) were necessary because the slaves would lapse into laziness. Furthermore, he did not join the abolitionist movement because he did not agree with their way of conducting themselves, and he felt that voluntary associations limited a person's autonomy. Therefore, he often chose to remain separate from organizations and reform movements. This middle position characterized his attitude about

Medicine is of all the Arts the most noble; but, not withstanding, owing to the ignorance of those who practice it, and of those who, inconsiderately, form a judgment of them, it is at present far behind all the other arts. Their mistake appears to me to arise principally from this, that in the cities there is no punishment connected with the practice of medicine (and with it alone) except disgrace, and that does not hurt those who are familiar with it. Such persons are like the figures which are introduced in tragedies, for as they have the shape, and dress, and personal appearance of an actor, but are not actors, so also physicians are many in title but very few in reality.
Experiments with Alternate Currents of High Potential and High Frequency
Experiments with Alternate Currents of High Potential and High Frequency
Nikola Tesla
¥23.14
It was in this interesting border region, and from among these valiant Eastern folk, that Nikola Tesla was born in the year 1857, and the fact that he, today, finds himself in America and one of our foremost electricians, is striking evidence of the extraordinary attractiveness alike of electrical pursuits and of the country where electricity enjoys its widest application. Mr. Tesla's native place was Smiljan, Lika, where his father was an eloquent clergyman of the Greek Church, in which, by the way, his family is still prominently represented. His mother enjoyed great fame throughout the countryside for her skill and originality in needlework, and doubtless transmitted her ingenuity to Nikola; though it naturally took another and more masculine direction. The boy was early put to his books, and upon his father's removal to Gospic he spent four years in the public school, and later, three years in the Real School, as it is called. His escapades were such as most quick witted boys go through, although he varied the programme on one occasion by getting imprisoned in a remote mountain chapel rarely visited for service; and on another occasion by falling headlong into a huge kettle of boiling milk, just drawn from the paternal herds. A third curious episode was that connected with his efforts to fly when, attempting to navigate the air with the aid of an old umbrella, he had, as might be expected, a very bad fall, and was laid up for six weeks.. ABOUT AUTHOR: Nikola Tesla (1856 –1943) was a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system. Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles. Tesla went on to pursue his ideas of wireless lighting and electricity distribution in his high-voltage, high-frequency power experiments in New York and Colorado Springs, and made early (1893) pronouncements on the possibility of wireless communication with his devices. He tried to put these ideas to practical use in an ill-fated attempt at intercontinental wireless transmission, his unfinished Wardenclyffe Tower project. In his lab he also conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging. He also built a wireless controlled boat, one of the first ever exhibited. Tesla was renowned for his achievements and showmanship, eventually earning him a reputation in popular culture as an archetypal "mad scientist". His patents earned him a considerable amount of money, much of which was used to finance his own projects with varying degrees of success. He lived most of his life in a series of New York hotels, through his retirement. Tesla died on 7 January 1943. His work fell into relative obscurity after his death, but in 1960 the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor. There has been a resurgence in popular interest in Tesla since the 1990s.

El origen de las especies (The origin of species, en inglés) o más exactamente El origen de las especies mediante la selección natural o la conservación de las razas favorecidas en la lucha por la vida es un libro escrito por Charles Darwin (1809 -1882), publicado el 24 de noviembre de 1859 (John Murrap, Londres); agotó los 1.250 ejemplares impresos en el primer día. En él, expuso por primera vez sus ideas sobre la selección natural y la teoría de la evolución. Esta obra es un trabajo fundamental dentro de la historia de la ciencia y la biología. En él, Darwin argumenta largamente su teoría sobre cómo los organismos evolucionan gradualmente por medio de la selección natural, presentando evidencias de su teoría acumuladas en su viaje en el HMS Beagle en los a?os 1831-1836. Su teoría se oponía ampliamente a las teorías vigentes en su época, creacionismo y catastrofismo. El libro puede ser leído por no especialistas. Aunque las ideas presentadas constituyen la base de la biología moderna continúan siendo controvertidas para ciertos grupos religiosos quienes se apoyan en una interpretación literal de textos religiosos a favor de explicaciones creacionistas.

Let the voice of Fame?From Age to Age repeat thy story,?Till thou hast won thyself a name?Exceeding even Euclid's glory!??This Tale originally appeared as a serial in The Monthly Packet, beginning in April, 1880. The writer's intention was to embody in each Knot (like the medicine so dexterously, but ineffectually, con-cealed in the jam of our early childhood) one or more mathematical questions "in Arithmetic, Algebra, or Geometry, as the case might be" for the amusement, and possible edification, of the fair readers of that Magazine.?LEWIS CARROLL???"Goblin, lead them up and down."???The ruddy glow of sunset was already fading into the sombre shadows of night, when two travellers might have been observed swiftly—at a pace of six miles in the hour—descending the rugged side of a mountain; the younger bounding from crag to crag with the agility of a fawn, while his companion, whose aged limbs seemed ill at ease in the heavy chain armour habitually worn by tourists in that district, toiled on painfully at his side.??As is always the case under such circumstances, the younger knight was the first to break the silence.?"A goodly pace, I trow!" he exclaimed. "We sped not thus in the ascent!"??"Goodly, indeed!" the other echoed with a groan. "We clomb it but at three miles in the hour."?"And on the dead level our pace is——?" the younger suggested; for he was weak in statistics, and left all such details to his aged companion.?"Four miles in the hour," the other wearily replied. "Not an ounce more," he added, with that love of metaphor so common in old age, "and not a farthing less!"??"'Twas three hours past high noon when we left our hostelry," the young man said, musingly. "We shall scarce be back by supper-time. Perchance mine host will roundly deny us all food!"?"He will chide our tardy return," was the grave reply, "and such a rebuke will be meet."?"A brave conceit!" cried the other, with a merry laugh. "And should we bid him bring us yet another course, I trow his answer will be tart!"
