La loi de la gravitation universelle - Newton, Euler et by Prosper Schroeder

By Prosper Schroeder

La Philosophiae Naturalis Principia Mathematica de Newton, marquait-elle le début d'une révolution scientifique, ou était-elle los angeles basic synthèse des idées d'un Kepler, Galilée ou Hooke? Clairaut, d'Alembert et Euler doutaient de l. a. validité de l. a. loi newtonienne et leurs idées firent progresser l. a. mécanique céleste qui atteignit l'état de «science normale» avec Le traité de mécanique céleste de Laplace, un siècle après Newton.

Galileo's Visions: Piercing the spheres of the heavens by by Marco Piccolino

By Marco Piccolino

Galileo is mostly a pioneer of technological know-how - particularly of mechanics and astronomy, yet some distance much less recognition has been paid to his paintings at the senses, and on imaginative and prescient particularly. during this publication, specialists at the heritage of technological know-how examine the unconventional ways that Galileo checked out the heavens via his telescope, and, within the approach, emphasized the significance of distinction phenomena and visible answer inside astronomical observations. He additionally defined the senses and their conception in phrases that chanced on an echo in doctrines complicated through 19th century sensory physiologists.

In a desirable and obtainable variety, Marco Piccolino and Nick Wade examine the clinical and philosophical paintings of Galileo Galilei from the actual point of view of his method of the senses (and in particular imaginative and prescient) as a method of buying reliable wisdom concerning the structure of the area. For Galileo the senses have been most likely ambiguous, for that reason trustworthy info in a position to penetrating the complexity of fact may possibly simply be bought by way of reading the sensory facts significantly. The philosophical heritage of Galileo's angle to the senses was once his expertise that nature had no longer constructed a particular language aimed toward speaking with senses quite often and human senses particularly. The tradition of his age used to be dependent customarily on mechanistic methods to the realm. during this context, Galileo's research of the senses corresponded heavily to a basic guideline of contemporary sensory body structure and psychophysics - the absence on the planet of particular sensory signs like sounds, shades, tastes, and odours.

Fully illustrated all through, this publication is a vital contribution to psychology and the imaginative and prescient sciences, yet extra largely to our wisdom of a pioneering determine within the heritage of technology

Bad astronomy: misconceptions and misuses revealed, from by Philip C. Plait

By Philip C. Plait

Encouraged via his well known website, www.badastronomy.com, this primary e-book via Plait (astronomy, Sonoma nation Univ.) debunks renowned myths and misconceptions in terms of astronomy and promotes technological know-how as a way of explaining our mysterious heavens. The paintings describes 24 universal astronomical fallacies, together with the ideals that the Coriolis impact determines the path that water drains in a bath and that planetary alignments could cause catastrophe on the earth. the writer sharply and convincingly dismisses astrology, creationism, and alien craft sightings and explains the foundations at the back of easy basic ideas (the immense Bang, why the sky is blue, etc.). even though a few may possibly locate him strident, Plait succeeds brilliantly simply because his transparent and comprehensible factors are convincing and sincere. this primary quantity in Wileys «Bad technological know-how» sequence is usually recommended for all libraries, specifically astronomy and folklore collections.

Hunting for Stars by Michel Maurette, Isabel A. Leonard

By Michel Maurette, Isabel A. Leonard

This paintings is ready meteorites and those that look for them. looking an evidence of the position micrometeorites have performed within the foundation and evolution of lifestyles in the world, readers persist with astronomers around the globe to seek for those mysterious black stones and tiny grains of cosmic airborne dirt and dust, and into the laboratory to check hypotheses at the beginning of our sunlight approach. The textual content discusses the dangers and stumbling blocks those scientists face, and gives an appreciation of the explanations and stakes taken with this box of study. subject matters lined contain discussions of Jupiter, the 1st rendezvous at the moon, the quest for isotopes and the pre-solar and nebular time scales.

Sidereus Nuncius by Galileo Galilei, Albert Van Helden

By Galileo Galilei, Albert Van Helden

;Sidereus Nuncius КНИГИ ; ИСТОРИЯ Автор:Galileo Galileo Название: Sidereus Nuncius Издательство: Venice Год: 1610 Формат: PDF Размер: 109 МБ Для сайта: www.mirknig.comИсторики науки почти единодушно считают, что Галилей если не изобрел, то усовершенствовал телескоп. Он изготовил трубу с увеличением в 30 раз и в августе 1609 продемонстрировал ее сенату Венеции. С помощью своей трубы Галилей начал наблюдение ночного неба. Результаты его наблюдений и составили эту книгу. Мысли, высказанные Галилеем в Звездном вестнике, никак не вписывались в рамки аристотелевского мировоззрения. Они совпадали со взглядами Коперника и Бруно. Так, Галилей считал Луну сходной по своей природе с Землей, а с точки зрения Аристотеля (и церкви) не могло быть и речи о подобии «земного» и «небесного». Так начались его расхождения со святой Инквизицией...Раритет - первоиздание звездных наблюдений Галилея. Была издана огромным по тем временам тиражом - 550 экземпляров, и практически сразу была издана пиратская копия этого произведения с рисунками, не слишком искусно исполненными в технике ксилографии. Книга оцифрована известной компанией 8vo, специализирующейся на высококачественном копировании старинных книг и манускриптов.0

Vom Urknall zum Durchknall : Die absurde Jagd nach der by Alexander Unzicker

By Alexander Unzicker

Die Physik ist bei der Jagd nach der Weltformel in eine Sackgasse geraten. Der Autor zeichnet nach, wie die theoretische Physik vom Weg abkam und nun mit immer größeren Spekulationsblasen in die Esoterik abdriftet. Witzig-bissig und mit unterhaltsamen Anekdoten, aber auch fundiert bis ins element nimmt er die heutige Physik aufs Korn und erinnert an die unbeantworteten Fragen, die die wirklichen Größen der Physik bewegt haben. Trotz oder gerade wegen der kritischen Töne ein faszinierendes und nachdenklich machendes Plädoyer für die Wissenschaft.

"Dies ist ein für Laien als auch für Studenten sehr interessant und unterhaltsam geschriebenes Buch über die Probleme der heutigen Physik und Kosmologie. Ich bin beeindruckt." Pavel Kroupa

"Ein zugleich amüsantes und informatives Buch." Ernst Peter Fischer

"Flott und humorvoll geschrieben und mit zahlreichen Anekdoten aus Wissenschaftsgeschichte und -betrieb bespickt, bereitet die Lektüre [...] dem jenseits des Konsens denkenden Zeitgenossen Vergnügen, es knarzt gewaltig im Gebälk des wissenschaftlichen Establishments!" Raum & Zeit

"Ich habe mich gleich festgelesen, wie es mir sonst nur in Krimis passiert" Michael Drieschner

The Observer's Guide to Planetary Motion: Explaining the by Dominic Ford

By Dominic Ford

To the bare eye, the main glaring defining characteristic of the planets is their movement around the evening sky. It was once this movement that allowed historical civilizations to unmarried them out as varied from fastened stars. “The Observer’s consultant to Planetary movement” takes each one planet and its moons (if it has them) in flip and describes how the geometry of the sun procedure supplies upward thrust to its saw motions.

Although the motions of the planets could be defined as easy elliptical orbits round the solar, we need to discover them from a selected vantage aspect: the Earth, which spins day-by-day on its axis and circles round the sunlight every year. The motions of the planets as saw relative to this spinning observatory tackle extra advanced styles. Periodically, gadgets turn into well-liked within the evening sky for a couple of weeks or months, whereas at different occasions they move too on the subject of the sunlight to be saw. “The Observer’s advisor to Planetary movement” presents actual tables of the simplest time for watching each one planet, including different striking occasions of their orbits, aiding beginner astronomers plan whilst and what to monitor. Uniquely all of the chapters comprises vast explanatory textual content, concerning the occasions indexed to the actual geometry of the sunlight System.

Along the best way, many questions are replied: Why does Mars take over years among apparitions (the instances whilst it really is noticeable from Earth) within the evening sky, whereas Uranus and Neptune take virtually precisely a 12 months? Why do planets seem larger within the evening sky while they’re seen within the wintry weather months? Why do Saturn’s jewelry seem to open and shut each 15 years? This e-book areas likely disparate astronomical occasions into an comprehensible third-dimensional constitution, permitting an appreciation that, for instance, excellent apparitions of Mars come round approximately each 15 years and that these in 2018 and 2035 can be pretty much as good as that noticeable in 2003.

Events are indexed for the period of time 2010-2030 and relating to rarer occasions (such as eclipses and apparitions of Mars) even longer time classes are coated. a brief last bankruptcy describes the seasonal visual appeal of deep sky items, which stick with an annual cycle because of Earth’s orbital movement round the Sun.

On the Topology and Future Stability of the Universe by Hans Ringström

By Hans Ringström

The normal place to begin in cosmology is the cosmological precept; the idea that the universe is spatially homogeneous and isotropic. After implementing this assumption, the single freedom left, so far as the geometry is worried, is the alternative of 1 out of 3 permissible spatial geometries, and one scalar functionality of time. Combining the cosmological precept with a suitable description of the problem results in the traditional types. it's worthy noting that those types yield particularly a profitable description of our universe.

However, although the universe may perhaps, or would possibly not, be nearly spatially homogeneous and isotropic, it truly is transparent that the cosmological precept isn't really precisely chuffed. This results in numerous questions. the main traditional one issues balance: given preliminary facts akin to an increasing version of the traditional style, do small perturbations supply upward thrust to options which are just like the long run? one other query matters the form of the universe: what are the constraints if we merely suppose the universe to seem virtually spatially homogeneous and isotropic to each observer?

The major function of the e-book is to handle those questions. even though, first of all, it is vital to strengthen the final idea of the Cauchy challenge for the Einstein-Vlasov equations. so as to to make the consequences available to researchers who're no longer mathematicians, yet who're accustomed to normal relativity, the booklet comprises an intensive prologue placing the consequences right into a extra basic context.
