Download Heavenly Mathematics: The Forgotten Art of Spherical by Glen Van Brummelen PDF

By Glen Van Brummelen

Heavenly Mathematics strains the wealthy background of round trigonometry, revealing how the cultures of classical Greece, medieval Islam, and the trendy West used this forgotten paintings to chart the heavens and the Earth. as soon as on the middle of astronomy and ocean-going navigation for 2 millennia, the self-discipline was once additionally a mainstay of arithmetic schooling for hundreds of years and taught largely until eventually the Fifties. Glen Van Brummelen explores this beautiful department of arithmetic and its position in old astronomy, geography, and cartography; Islamic spiritual rituals; celestial navigation; polyhedra; stereographic projection; and extra. He conveys the sheer fantastic thing about round trigonometry, delivering readers with a brand new appreciation of its based proofs and infrequently miraculous conclusions. Heavenly Mathematics is illustrated all through with attractive ancient photographs and informative drawings and diagrams. This specified compendium additionally beneficial properties easy-to-use appendixes in addition to workouts that initially seemed in textbooks from the eighteenth to the early 20th centuries.

Download Weird Comets and Asteroids: The Strange Little Worlds of the by David A. J. Seargent PDF

By David A. J. Seargent

This publication concentrates on the various strange elements of comets and asteroids. unusual habit of comets, reminiscent of outbursts and schisms, and the way asteroids can temporally act as comets are mentioned, including the prospective possibility of Centaurs-class gadgets just like the Taurid complex.

Recent years have noticeable the excellence among comets and asteroids develop into much less well-liked. Comets in "asteroid" orbits and vice versa became virtually ordinary and a clearer view of the function of small our bodies within the formation of the sunlight method and their impact in the world has develop into obvious. Seargent covers this improvement intimately by way of together with new info and knowledge from house probes.

Download Die Schwarzschild-de Broglie Modifikation der speziellen by Siegfried Gantert PDF

By Siegfried Gantert

Wissenschaftliche Studie aus dem Jahr 2014 im Fachbereich Physik - Astronomie, , Sprache: Deutsch, summary: Für Feldbosonen, in dieser Arbeit gleichbedeutend für Kondensate aus Spin 0-Teilchen, wird hier eine modifizierte shape der speziellen Relativitätstheorie, kurz SBM, präsentiert. Sie leitet sich von der Hypothese ab, dass bei relativistischen Geschwindigkeiten eine Mindestgröße der Ortsunschärfe ∆x > 2∙rS (rS = Schwarzschildradius) wirksam wird, aus der sich je nach Größe der Feldbosonen unterschiedliche Grenzgeschwindigkeiten zero < v(l,n) < c ableiten lassen. Entsprechend dem SBM-Modell werden Feldbosonen unterhalb einer definierten Phasengrenze durch spontane Symmetriebrechung massiv. Durch Wirkung der Gravitation können Feldbosonen zu größeren Kondensaten verschmelzen, wodurch ihre effektive Masse abnimmt und infolge dessen auch der gravitative Zusammenhalt auf großen Skalen.

Download Island Universes: Structure and Evolution of Disk Galaxies by R. S. Jong PDF

By R. S. Jong

This ebook comprises an up to date evaluation of the constitution and evolution of disk galaxies from either the observational and theoretical perspective. The booklet is the complaints of the 'Island Universes' convention held on the island of Terschelling, The Netherlands in July 2005, which attracted approximately a hundred thirty specialists and scholars within the box. The convention was once equipped as a tribute to Dr. Piet C. van der Kruit for receiving the honorary Jacobus C. Kapteyn Professorship in Astronomy. The 8 topical topics mentioned on the assembly are: 1) homes of Stellar Disks, 2) Kinematics and Dynamics of Disk Galaxies, three) Bars, Spiral constitution, and Secular Evolution in Disk Galaxies, four) The Outskirts and surroundings of Disk Galaxies, five) Interstellar subject, 6) (Evolution of) big name Formation in Galactic Disks, 7) Disk Galaxies via Cosmic Time, and eight) Formation types of Disk Galaxies. those court cases are concluded with a convention precis reflecting at the most vital fresh development and awesome problems.

Download Bayesian Field Theory by Jörg C. Lemm PDF

By Jörg C. Lemm

Ask a standard mathematician the most likely final result of a coin-toss, and he'll answer that no facts exists on which to base one of these prediction. Ask a Bayesian, and he'll study the coin, finish that it was once not likely tampered with, and are expecting heads in one thousand tosses; a next scan may then be used to refine this prediction. The Bayesian procedure, in different phrases, allows using past wisdom whilst trying out a hypothesis.

Long the province of mathematicians and statisticians, Bayesian tools are utilized during this ground-breaking booklet to difficulties in state of the art physics. Joerg Lemm deals sensible examples of Bayesian research for the physicist operating in such components as neural networks, synthetic intelligence, and inverse difficulties in quantum concept. The e-book additionally contains nonparametric density estimation difficulties, together with, as distinct circumstances, nonparametric regression and development popularity. Thought-provoking and certain to be arguable, Bayesian box Theory may be of curiosity to physicists in addition to to different experts within the speedily transforming into variety of fields that utilize Bayesian methods.

Download Die Vierte Dimension der Schöpfung: Gott, Natur und Sehen in by Reiner Kümmel PDF

By Reiner Kümmel

Ist Gott, wie ihn der christliche Glaube bekennt, vereinbar mit dem naturwissenschaftlichen Weltbild?

Physiker sind sich weitgehend darin einig, dass ihre auf Experimenten in der Energie-Materie-Welt beruhende Wissenschaft in Sachen faith nichts widerlegen oder beweisen kann. Und dennoch wird die Frage weiterhin viel diskutiert.

Reiner Kümmel, Professor der theoretischen Physik, beschreibt in diesem Buch das Naturverständnis der modernen Physik, das von Relativitätstheorie und Quantenmechanik geprägt wird. Demgemäß ist die Zeit die vierte measurement der Welt. Zusammen mit den drei räumlichen Dimensionen ist sie im Urknall aus Energie entstanden. Ihr Fließen macht sich durch die Produktion von Entropie, sprich Unordnung, bemerkbar, die unsere Gesellschaft in Krise und Umbruch treibt. Beobachtete natürliche Ereignisse und Strukturen zeigen uns eine Welt, in der Gegegensätze zusammenfallen. Der Autor weist darauf hin, dass diese "Coincidentia Oppositorum" auch Gott eignet. Sie führt zur "Creatio Continua", in der Gott, überzeitlich und jederzeit, die gesamte Schöpfung von ihrem Anfang bis zum Ende schafft und sieht.

Das Buch versucht eine Darstellung des Sehens in die Zeit, an dem vielleicht auch wir einst teilhaben dürfen. Es wendet sich an alle, die sich fragen, woher wir kommen und wohin wir gehen und eröffnet eine Sicht auf Gott und die Welt, in der Glaube und Naturwissenschaft intestine zusammen passen.

Download Taking the Back off the Watch: A Personal Memoir: 381 by Thomas Gold,Simon Mitton PDF

By Thomas Gold,Simon Mitton

Thomas Gold (1920-2004) had a curious brain that loved to unravel difficulties. He used to be probably the most amazing astrophysicists within the moment 1/2 the 20th century, and he attracted controversy all through his occupation. in keeping with a full-length autobiography left at the back of by way of Thomas Gold, this ebook used to be edited by means of the astrophysicist and historian of technology, Simon Mitton (University of Cambridge).

The e-book is a retrospective on Gold’s awesome lifestyles. He fled from Vienna in 1933, finally settling in England and finishing an engineering measure at Trinity university in Cambridge. throughout the conflict, he labored on naval radar examine along Fred Hoyle and Hermann Bondi – which, in an not going chain of occasions, finally resulted in his operating with them on steady-state cosmology. In 1968, presently after their discovery, he supplied the reason of pulsars as rotating neutron stars.

In his ultimate place at Cornell, he and his colleagues persuaded the USA safeguard division to fund the conversion of the enormous radio telescope at Arecibo in Puerto Rico right into a significant software for radio astronomy. Gold’s pursuits coated body structure, astronomy, cosmology, geophysics, and engineering.

Written in an exciting kind and with an both exciting foreword by means of Freeman Dyson, this ebook constitutes a big historic record, made obtainable to all these drawn to the heritage of science.
