Geometry (8,858 Books)


Geometry (Ancient Greek: ?e?µet??a; geo- 'earth', -metri 'measurement') 'Earth-measuring' is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. Geometry is one of the oldest mathematical sciences. Initially a body of practical knowledge concerning lengths, areas, and volumes, in the 3rd century BC geometry was put into an axiomatic form by Euclid, whose treatment—Euclidean geometry—set a standard for many centuries to follow.

Observing Spatio-temporal Clustering and Separation Using Intereve...

By: H. Kantz; R. C. Batac

Description: Max-Planck-Institut für Physik komplexer Systeme, Nöthnitzer Str. 38, 01187, Dresden, Germany. Past studies that attempted to quantify the spatio-temporal organization of seismicity have defined the conditions by which an event and those that follow it can be related in space and/or time. In this work, we use the simplest measures of spatio-temporal separation: the interevent distances R and interevent times T between pairs of successive ev...

Epitaph on the Earl of Strafford

By: John Cleveland

Poetry

Excerpt: HERE lies wise and valiant dust // Huddled up 'twixt fit and just, // Strafford, who was hurried hence // 'Twixt treason and convenience. // He spent his time here in a mist, // A Papist, yet a Calvinist; // His Prince's nearest joy and grief, // He had, yet wanted all relief; // The prop and ruin of the state; // The people's violent love and hate; // One in extremes loved and abhorred. // Riddles lie here, or in a word - // Here lies blood; and let it lie // S...

Narrative and Miscellaneous Papers, Volume Ii

By: Thomas de Quincey

Meantime, what Kant understood by being old, is something that still remains to be explained. If one stumbled, in the steppes of Tartary, on the grave of a Megalonyx, and, after long study, had deciphered from some pre-Adamite heiro-pothooks, the following epitaph, ?Hic jacet a Megalonyx, or Hic jacet a Mammoth, (as the case might be,) who departed this life, to the grief of his numerous acquaintance in the seventeen thousandth year of his age,??of course, one would be s...

The Epitome of the Divine Institutes

By: Lactantius

First a question arises: Whether there is any providence which made or governs the world? That there is, no one doubts, since of almost all the philosophers, except the school of Epicurus, there is but one voice and one opinion, that the world could not have been made without a contriver, and that it cannot exist without a ruler. Therefore Epicurus is refuted not only by the most learned men, but also by the testimonies and perceptions of all mortals. For who can doubt r...

Introduction to Mechanics and Symmetry Q

By: Jerrold E. Marsden

Physics Literature

Excerpt: Symmetry and mechanics have been close partners since the time of the founding masters: Newton, Euler, Lagrange, Laplace, Poisson, Jacobi, Hamilton, Kelvin, Routh, Riemann, Noether, Poincare, Einstein, Schraodinger, Cartan, Dirac, and to this day, symmetry has continued to play a strong role, especially with the modern work of Kolmogorov, Arnold, Moser, Kirillov, Kostant, Smale, Souriau, Guillemin, Sternberg, and many others. This book is about these development...

GPS Versus Galileo : Balancing for Position in Space

By: Scott W. Beidleman

This study investigates Europe’s motives to develop the independent satellite navigation system known as Galileo despite the existence of America’s successful global positioning system (GPS). The study begins by analyzing both systems to familiarize the reader with global navigation satellite systems (GNSS) and to provide an understanding of the strengths and weaknesses of GPS and Galileo, as well as the systems’ similarities and differences. Although the two systems h...

Maximus in Minimis : Aphlorisms in Unistiches

By: Florentin Smarandache

Etymologically, aphorism + floral = aph(L)orism, which is a short reflection written on a floral design, or a short poetry accompanied by an artistic background. They are colorful contemplations. Maximus in minimis (Lat.) means very much in very little [max in min], or condensed thought, or ideating essence. They are actually maxims, adages, sayings mostly in one line (uni-stich) with a title, as a metaphoric statement, a breathing momentum that oils our soul.

Nonchalantly : The wind with its mantle steps lightly. Skin Condition : The Sun has spots too. At what time? When it rains, God cries. Atmosphere : Blue, as the sky dirtied by clouds. Bright : A balcony full of Sun. Natural disaster : The swans look drunk on the fetid lake. Surprisingly : The crow is a beautiful black. Elegant woman : A bird high on her legs. Most powerful chess piece : You are a queen but only in the dark. Medicinal plant : You’re a flower but ...

The Renaissance of Science : The Story of the Atom and Chemistry

By: Ph.D. Albert Martini

The 2000 year history of the atom and chemistry, from the Classic Greek Era to the present, is described in 800 pages, depicted with some 300 pictures and illustrations. This history of the atom and chemistry discusses the lives of about 180 chemists and physicists, through the evolution of several stages of development, representing the most important scientific accomplishments. The most significant discoveries in chemistry and physics are presented chronologicall...

INTRODUCTION It is a genuine pleasure and challenge for me to try to express the full extent of my emotions and reasons for writing this book on the STORY OF THE ATOM AND THE SCIENCES, with special reference to the CHEMICAL SCIENCES. In one sentence, I can distill the essence of the purpose for this study by simply stating that it has been a labor of love that transcended the written word because sentiments and ideas belong in the realm of the ethereal and the phil...

Vital and Health Statistics

By: Jennifer H. Madans, Ph. D.

The National Health and Nutrition Examination Surveys (NHANES) are designed to provide periodic information on the health and nutritional status of the civilian noninstitutionalized population of the United States. The survey program was begun in 1960 with three surveys of health status, the National Health Examination Surveys (NHES) (19–21). In 1970, an expanded nutrition component was added to provide data with which to assess nutritional status and dietary practices. ...
