Mary Somerville and the World of Science by Allan Chapman

By Allan Chapman

Mary Somerville (1780-1872), after whom Somerville university Oxford used to be named, used to be the 1st lady scientist to win a global popularity completely in her personal correct, instead of via organization with a systematic brother or father.

She was once lively in astronomy, probably the most not easy parts of technological know-how of the day, and flourished within the designated British culture of Grand Amateurs, who paid their very own manner and weren't affiliated with any educational institution.

Mary Somerville used to be to technology what Jane Austen was once to literature and Frances Trollope to go back and forth writing. Allan Chapman’s shiny account brings to gentle the tale of an outstanding lady, whose achievements in a box ruled through males need to be very generally known.

The Extraterrestrial Life Debate, Antiquity to 1915: A by Michael J. Crowe

By Michael J. Crowe

This ebook offers key records from the pre-1915 heritage of the extraterrestrial lifestyles debate. Introductions and commentaries accompany every one resource record, a few of that are released right here for the 1st time or in a brand new translation. Authors integrated are Aristotle, Lucretius, Aquinas, Nicholas of Cusa, Galileo, Kepler, Pascal, Fontenelle, Huygens, Newton, Pope, Voltaire, Kant, Paine, Chalmers, Darwin, Wallace, Dostoevski, Lowell, and Antoniadi, between others. Michael J. Crowe has compiled an intensive bibliography now not to be had in different sources.

These fabrics demonstrate that the extraterrestrial lifestyles debate, instead of being a comparatively sleek phenomenon, has prolonged all through approximately all Western historical past and has concerned a lot of its major intellectuals. The readings additionally exhibit that trust in extraterrestrial existence has had significant results on technological know-how and society, and that metaphysical and non secular perspectives have permeated the talk all through a lot of its history.
 
"This is a invaluable ebook that's not to be had anyplace else. . . . Crowe's objective is to permit the reader see the unique phrases of the authors who mentioned different worlds. Crowe places those records in context by means of his large advent and observation. . . . any such resource booklet serves an immense function, and is perfect for instructing and producing dialogue at school. the topic is of accelerating significance as we discover a growing number of in regards to the probabilities of extraterrestrial lifestyles via present disciplines reminiscent of astrobiology, bioastronomy, and the hunt for Extraterrestrial Intelligence." —Steven J. Dick, Director, NASA historical past department, NASA
 
"Having confirmed himself because the world’s authority at the background of the debates approximately extraterrestrial lifestyles within the eighteenth and 19th centuries, Michael Crowe is completely situated to provide this resource booklet. The introductory commentaries at the excerpts from basic assets he has so judiciously chosen demonstrate many times that nobody else is aware this topic in addition to he does." —Frederick Gregory, collage of Florida

 

"The Extraterrestrial existence Debate gives new aspiring to the notice 'treasury.' Michael Crowe bargains us greater than 2000 years of golden materials—wrought by way of the superb alchemy of technological know-how, faith, philosophy, and sheer imagination—about a subject matter as alive at the present time because it ever was once: ET, with all his cousins and ancestors. the diversity of authors the booklet showcases, and the intensity of context Crowe presents, will make his huge anthology the start line for destiny explorations of this wealthy vein of human thought." —Dennis Danielson, college of British Columbia

“There are a great deal of books on ET, yet just a small variety of them take a old procedure . . . someone drawn to the background of the extraterrestrial lifestyles debate may be drawn to this e-book; it does whole in a definite method prior historic paintings performed through Steven Dick and Michael Crowe by means of supplying huge parts of unique texts instead of in basic terms brief quotations from them. . . . all of the numerous views, spiritual, literary, astronomical, philosophical, look correctly represented. The multidisciplinary element of the controversy comes throughout good from the authors selected.” —Marie I. George, St. John’s University

“Extraterrestrials won't have invaded the Earth bodily yet for hundreds of years they've got performed so mentally. in lots of a guise they've got seemed not just in works of fiction but additionally in critical astronomical, philosophical and theological debate. it really is most unlikely to open Michael Crowe's good-looking and carefully ready anthology of basic resources with no being drawn into perpetually interesting disputes in regards to the chance and personality of extraterrestrial existence. Savoring the various twists and turns in controversies that experience prolonged a ways past the confines of well known astronomy, Professor Crowe has supplied scholars and specialists alike with a beneficiant and integral source. it really is tough to withstand his invitation to enquire for ourselves the innumerable, and infrequently extraordinary, ways that the assumption of clever lifestyles on different worlds has formed and been formed by means of perennial Earthly concerns.” —John Hedley Brooke, Andreas Idreos Professor Emeritus of technology and faith, collage of Oxford

Variations on a Theme by Kepler by Victor Guillemin; Shlomo Sternberg; American Mathematical

By Victor Guillemin; Shlomo Sternberg; American Mathematical Society

This ebook relies at the Colloquium Lectures awarded via Shlomo Sternberg in 1990. The authors delve into the mysterious position that teams, specifically Lie teams, play in revealing the legislation of nature via targeting the standard instance of Kepler movement: the movement of a planet less than the charm of the sunlight in response to Kepler's legislation. Newton discovered that Kepler's moment law--that equivalent components are swept out in equivalent times--has to do with the truth that the strength is directed radially to the solar. Kepler's moment legislation is basically the statement of the conservation of angular momentum, reflecting the rotational symmetry of the process in regards to the beginning of the strength. In cutting-edge language, we might say that the crowd $O(3)$ (the orthogonal staff in 3 dimensions) is answerable for Kepler's moment legislations. through the top of the 19th century, the inverse sq. legislation of charm was once noticeable to have $O(4)$ symmetry (where $O(4)$ acts on a component of the six-dimensional part house of the planet). Even better teams have in view that been chanced on to be interested in Kepler movement. In quantum mechanics, the instance of Kepler movement manifests itself because the hydrogen atom. Exploring this circle of principles, the 1st a part of the ebook used to be written with the overall mathematical reader in brain. the rest of the ebook is aimed toward experts. It starts with an indication that the Kepler challenge and the hydrogen atom show $O(4)$ symmetry and that the shape of this symmetry determines the inverse sq. legislations in classical mechanics and the spectrum of the hydrogen atom in quantum mechanics. the gap of regularized elliptical motions of the Kepler challenge (also often called the Kepler manifold) performs a significant function during this publication. The final component to the e-book experiences some of the cosmological versions during this comparable conformal type (and having various isometry teams) from the perspective of projective geometry. The computation of the hydrogen spectrum offers a demonstration of the primary that enlarging the part house can simplify the equations of movement within the classical atmosphere and reduction within the quantization challenge within the quantum environment. The authors supply a quick precis of the homological quantization of constraints and a listing of contemporary purposes to many fascinating finite-dimensional settings. The publication closes with an overview of Kostant's conception, during which a unitary illustration is linked to the minimum nilpotent orbit of $SO(4,4)$ and during which electromagnetism and gravitation are unified in a Kaluza-Klein-type conception in six dimensions
