Lecture delivered before the International Congress of Mathematicians at Paris in 1900 and subsequently published in the Bulletin of the American Mathematical Society Vol. 8 (1902), 479-481.

Νόμοι (Laws) is Plato's final dialogue written after his attempt to advise the tyrant Dionysius II of Syracuse. The dialogue takes place between: an Athenian Stranger (Socrates? A god in human form?); the quiet Lacedaemonian Megillus; and the Cretan Cleinias. The Stranger asks whether humans live to be more effective at waging war or if there is something more important a legislator should seek to achieve. During their pilgrimage Cleinias discloses his role in the establishment of a new colony...

Do you know the difference between sedimentary, igneous and metamorphic rocks? Are you interested in their geologic origin, chemical composition or how each type affects the landscape? Do you know the differences between limestone, granite and marble as building materials? You will find these and lots of other interesting facts about rocks in this second edition of "Rocks and Their Origins" published in 1922. The author, Grenville A. J. Cole, was an English geologist, Professor of Geology in the Royal College of Science for Ireland and an avid cyclist.

Published in 1911 as part of the "Harper's Library of Living Thought," this volume presents an introduction to the chemistry of cells in the context of plant physiology and gives an interesting overview of the field of biochemistry and related sciences at the time. The author, Frederick Czapek, was a Czech botanist and professor of Plant Physiology at the University of Prague. He is perhaps best known for his two-volume work on Plant Physiology, "Biochemie der Pflanzen" and for Czapek solution agar or Czapek-Dox medium, a culture medium for cultivation of fungus species such as Aspergillus and Penicillium molds.

Buzz, buzz, buzz. A fascinating and beautifully written explanation of the life of the honey bee. Is the queen the master of the hive or just a hard working servant? What is the purpose of the drones? Why do bees make honey? Do bees ever sleep? Why do bees swarm? Maeterlinck, who won the Noble Prize for Literature, wrote a more scholarly work called The Life of the Bee but then rewrote it in simpler terms so that children could appreciate what goes in a hive. The book describes in simple language the inner workings of a hive from its beginning with a swarm to the fully functional hive with thousands of workers, drones and a queen busily building, repairing and gathering.

Teenagers Peggy Prescott and her brother Roy share a love of aviation that they inherited from their late father. Mr. Prescott had always dreamed of building an aeroplane that would be free of the defects of planes already invented. Peggy and Roy manage to build a plane starting with the framework their father had begun. Peggy christens it ‘The Golden Buttefly’ and she and Roy are determined to enter it in a young aviator’s contest for a prize of $5000. The Prescotts need the money desperately to save the home they share with their aunt which is about to be taken from them by the rather nasty banker, Mr...

The Republic is a Socratic dialogue written by Plato around 380 BC concerning the definition of justice and the order and character of the just city-state and the just man. It is Plato's best-known work and has proven to be one of the most intellectually and historically influential works of philosophy and political theory. In it, Socrates along with various Athenians and foreigners discuss the meaning of justice and examine whether or not the just man is happier than the unjust man by considering a series of different cities coming into existence "in speech", culminating in a city (Kallipolis) ruled by philosopher-kings; and by examining the nature of existing regimes...

This dialogue brings Socrates face to face with the famous sophist Gorgias and his followers. It is a work likely completed around the time of "Republic" and illuminates many of the spiritual ideas of Plato. The spirituality, as Jowett points out in his wonderful introduction, has many ideas akin to Christianity, but is more generous as it reserves damnation only for the tyrants of the world. Some of the truths of Socrates, as presented by Plato, shine forth in this wonderful work on sophistry and other forms of persuasion or cookery.

A good book by the oil revolutionist of the 20th century. As they say "Men should listen to experience" and this book is all about the experience of the second highest taxpayer of the US during the 20's. Though it is not in the book, this is a small poem he wrote:I was early taught to work as well as play,My life has been one long, happy holiday;Full of work and full of play-I dropped the worry on the way- And God was good to me everyday.

If this book were written today, it would be called "The Story of the World's Rubbish".That may not sound a promising subject for a book, but we are taken on a journey all over the world (and beyond) to explain the many varieties of dust and refuse - animal, vegetable and mineral - how it is made both by man and by nature, what happens to it, and why we need it. We find that recycling is nothing new: man has been doing it for centuries, and nature has been doing it for billions of years. As every schoolboy knows, 'matter is neither created nor destroyed', so it stands to reason that every particle of it must be somewhere...

MANUAL OF SURGERY, OXFORD MEDICAL PUBLICATIONSBY ALEXIS THOMSON, F.R.C.S.Ed.PREFACE TO SIXTH EDITION Much has happened since this Manual was last revised, and many surgical lessons have been learned in the hard school of war. Some may yet have to be unlearned, and others have but little bearing on the problems presented to the civilian surgeon. Save in its broadest principles, the surgery of warfare is a thing apart from the general surgery of civil life, and the exhaustive literature now available on every aspect of it makes it unnecessary that it should receive detailed consideration in a manual for students...

The Surprising Adventures of Bampfylde Moore Carew recounts the wide-ranging exploits of a real-life rogue – a wily professional mendicant who roams 18th-century England extracting charity from merchants, clergyman, and members of the landed gentry alike, employing in his craft an ingenious variety of deceptions and disguises put on for the purpose. Often he impersonates a shipwreck-surviving seaman and uses his wide knowledge of foreign parts and personages to achieve plausibility. Or he might appear on a doorstep as a destitute woman in widow's weeds, toting borrowed babes to enhance the effect...

SEARCHLIGHTS ON HEALTH. THE SCIENCE OF EUGENICSBy PROF. B.G. JEFFERIS, M.D., PH. D. KNOWLEDGE IS SAFETY. 1. The old maxim, that Knowledge is power, is a true one, but there is still a greater truth: KNOWLEDGE IS SAFETY. Safety amid physical ills that beset mankind, and safety amid the moral pitfalls that surround so many young people, is the great crying demand of the age. 2. CRITICISM.--This work, though plain and to some extent startling, is chaste, practical and to the point, and will be a boon and a blessing to thousands who consult its pages...

Physiology and Hygiene for Secondary Schoolsby Francis M. Walters, A.M.PREFACE The aim in the preparation of this treatise on the human body has been, first, to set forth in a teachable manner the actual science of physiology; and second, to present the facts of hygiene largely as applied physiology. The view is held that right living consists in the harmonious adjustment of one's habits to the nature and plan of the body, and that the best preparation for such living is a correct understanding of the physical self...

YOUNG FOLKS' LIBRARYA BOOK OF NATURAL HISTORYTHE WONDER OF LIFE, BY PROFESSOR, T. H. HUXLEY. Every one has seen a cornfield. If you pluck up one of the innumerable wheat plants which are fixed in the soil of the field, about harvest time, you will find that it consists of a stem which ends in a root at one end and an ear at the other, and that blades or leaves are attached to the sides of the stem. The ear contains a multitude of oval grains which are the seeds of the wheat plant. You know that when these seeds are cleared from the husk or bran in which they are enveloped, they are ground into fine powder in mills, and that this powder is the flour of which bread is made...

The Notebooks of Leonardo Da VinciPREFACEA singular fatality has ruled the destiny of nearly all the most famous of Leonardo da Vinci's works. Two of the three most important were never completed, obstacles having arisen during his life-time, which obliged him to leave them unfinished; namely the Sforza Monument and the Wall-painting of the Battle of Anghiari, while the third--the picture of the Last Supper at Milan--has suffered irremediable injury from decay and the repeated restorations to which it was recklessly subjected during the XVIIth and XVIIIth centuries...

GENERAL SCIENCEBY BERTHA M. CLARK, PH.D.PREFACEThis book is not intended to prepare for college entrance examinations; it will not, in fact, prepare for any of the present-day stock examinations in physics, chemistry, or hygiene, but it should prepare the thoughtful reader to meet wisely and actively some of life's important problems, and should enable him to pass muster on the principles and theories underlying scientific, and therefore economic, management, whether in the shop or in the home. We...

Young Folks' Library, Selections from the Choicest LiteratureTHE MARVELS OF NATURE BY EDWARD S. HOLDEN, M.A., Sc.D. LL.D. The Earth, the Sea, the Sky, and their wonders--these are the themes of this volume. The volume is so small, and the theme so vast! Men have lived on the earth for hundreds of the sands of years; and its wonders have increased, not diminished, with their experience. To our barbarous ancestors of centuries ago, all was mystery--the thunder, the rainbow, the growing corn, the ocean, the stars...

The Anatomy of Melancholy is a book by Robert Burton, first published in 1621. On its surface, the book is a medical textbook in which Burton applies his large and varied learning in the scholastic manner to the subject of melancholia (which includes what is now termed clinical depression). Though presented as a medical text, The Anatomy of Melancholy is as much a sui generis work of literature as it is a scientific or philosophical text, and Burton addresses far more than his stated subject. In...

Charles Darwin LL.B F.R.S was the discoverer of evolution and argued the role of "natural selection" in directing the evolution of species. Darwin also had an interest in the formation of soils (moulds) that began relatively early in his life, with a paper "On the Formation of Vegetable Moulds" delivered to the Geological Society of London in 1937. Darwin's last book, The Formation of Vegetable Moulds through the Action of Worms with Observations on their Habits, was completed in 1881.

The first Anti-Slavery Convention of American Women met in New York City in May, 1837. Members at the Convention came from all walks of life and included such prominent women as Mary Parker, Lucretia Mott, the Grimke sisters, and Lydia Maria Child. One outcome of this important event was a statement of the organization’s role in the abolitionist movement as expressed in AN ADDRESS TO FREE COLORED AMERICANS, which begins: “The sympathy we feel for our oppressed fellow-citizens who are enslaved...

Physics (Greek: Φυσικὴ ἀκρόασις; Latin: Physica, or Physicae Auscultationes) discusses concepts including: substance, accident, the infinite, causation, motion, time and the Prime Mover.

Handbook of Nature-Study was written by Anna Botsford Comstock during an era of growing societal concern for man's treatment of the natural world. Out of this concern grew the nature study movement which sought to teach science to school children (and others) through direct observation of nature by the students themselves instead of by the study of nature books. The book is written as a guide for teachers instructing their classes in nature study and includes a wealth of information about plants, animals, the earth, and the sky along with suggestions for guiding students in their observations...

In September 2005, the House of Representatives created the Select Bipartisan Committee to Investigate the Preparation for and Response to Hurricane Katrina. The Committee was charged with conducting "a full and complete investigation and study and to report its findings to the House not later than February 15, 2006, regarding-- (1) the development, coordination, and execution by local, State, and Federal authorities of emergency response plans and other activities in preparation for Hurricane Katrina; and (2) the local, State, and Federal government response to Hurricane Katrina...

One man's opinion of woman in 1894. Charles Harper believes in the superiority of the male sex and the subordination of the female. He paints an entire gender with the same brush. He believes all women to be identical in mind (illogical) and body (knock-kneed) and vastly inferior to the male. He presents 'facts' to support his opinions: "Woman's Mission is Submission" "for woman has ever been the immoral sex" "how truly like nature their tongues say 'No,' when their hearts throb 'Yes, yes!'" "She...

The clearness, simpicity, and charm of the great French naturalist's style are nowhere better illustrated than in this work, which in its variety of subject-matter and apt use of entertaining anecdote rivals "The Story-Book of Science," already a favorite with his readers. Such instances of antiquated usage or superseded methods as occur in these chapters of popular science easily win our indulgence because of the literary charm and warm human quality investing all that the author has to say. -- Translator (Introductory Note).

On April 20, 2010, the Macondo well blew out, costing the lives of 11 men, and beginning a catastrophe that sank the Deepwater Horizon drilling rig and spilled over 4 million barrels of crude oil into the Gulf of Mexico. The spill disrupted an entire region's economy, damaged fisheries and critical habitats, and brought vividly to light the risks of deepwater drilling for oil and gas - the latest frontier in the national energy supply. Soon after, President Barack Obama appointed a seven-member Commission to investigate the disaster, analyze its causes and effects, and recommend the actions necessary to minimize such risks in the future...
