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.

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...

After having written and released an initial draft of this proclamation in September of 1862, minor changes were made and Lincoln signed it on January 1st, 1863. It declared free the slaves in 10 states not then under Union control, with exemptions specified for areas already under Union control in two states. Lincoln spent the next 100 days preparing the army and the nation for emancipation, while Democrats rallied their voters in the 1862 off-year elections by warning of the threat freed slaves posed to northern whites...

Reputedly inspired by the Sherlock Holmes stories, Austrian criminal jurist and examining magistrate Hans Gross wrote the first handbook on criminal investigation. This treatise covers everything from the qualities of a good investigating officer and how to utilize various experts, to tactics employed by criminals, how to analyze footprints and blood stains, and ways that criminals perpetrate crimes. Some of the remarks relate directly to India, such as disguising one's caste.Volume 1 (of 3) consists of Part 1 of the 4 parts in the work.

The Elements of Mammalogy is one of seven in a Series of First Books of Natural History Prepared for the Use of Schools and Colleges. This succinct little textbook from 1845 presents an introduction to mammalogy. The information, albeit not current, is still interesting and of use as a general overview of mammal biology. The classification of mammals has changed considerably since this time. The author was a surgeon in the U.S. Navy and president of the Academy of Natural Sciences.

"The study here presented embodies the findings of an investigation into the recent [1919-1920] deportations of persons deemed to be unlawfully in the country. . . Its purpose is to call public attention to practices that are inconsistent with the American tradition of justice and fair-play."

While a bit outdated in many of the more complex descriptions of several of the phenomena described, this book is nonetheless still fun and relevant for a person interested in basic chemistry or physics tricks, and the devices built in the book can be easily replicated with more modern materials. The book is split up into many little experiments, tricks, with an explanation on how it works, what's happening, and how to reproduce the effects at home.

The World of Sound consists of six lectures delivered before a juvenile audience at the Royal Institution, Christmas 1919. The Royal Institution Christmas Lectures are a series of lectures on a single topic, which have been held at the Royal Institution in London each year since 1825, except several years during the Second World War. The lectures present scientific subjects to a general audience, including young people, in an informative and entertaining manner. Michael Faraday initiated the first Christmas Lecture series in 1825, at a time when organised education for young people was scarce...

In the 18th and early 19th centuries, it was common for discoveries in branches of science such as botany, astronomy and medicine to be described in book-length treatises in verse. By the end of the 19th century this mode of popularising science was falling from favour as the studies of science and the humanities diverged and study became more specialised.This small selection of somewhat lighter-hearted verse written by distinguished scientists and mathematicians of the day includes poems by James Clerk Maxwell, William J. Macquorn Rankine and James Joseph Sylvester.
