Large Igneous Provinces: a Driver of Global Environmental and Biotic Changes, Geophysical Monograph 255, First Edition
2 Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement Jennifer Kasbohm1, Blair Schoene1, and Seth Burgess2 ABSTRACT There is an apparent temporal correlation between large igneous province (LIP) emplacement and global envi- ronmental crises, including mass extinctions. Advances in the precision and accuracy of geochronology in the past decade have significantly improved estimates of the timing and duration of LIP emplacement, mass extinc- tion events, and global climate perturbations, and in general have supported a temporal link between them. In this chapter, we review available geochronology of LIPs and of global extinction or climate events. We begin with an overview of the methodological advances permitting improved precision and accuracy in LIP geochro- nology. We then review the characteristics and geochronology of 12 LIP/event couplets from the past 700 Ma of Earth history, comparing the relative timing of magmatism and global change, and assessing the chronologic support for LIPs playing a causal role in Earth’s climatic and biotic crises. We find that (1) improved geochronol- ogy in the last decade has shown that nearly all well-dated LIPs erupted in < 1 Ma, irrespective of tectonic set- ting; (2) for well-dated LIPs with correspondingly well-dated mass extinctions, the LIPs began several hundred ka prior to a relatively short duration extinction event; and (3) for LIPs with a convincing temporal connection to mass extinctions, there seems to be no single characteristic that makes a LIP deadly. Despite much progress, higher precision geochronology of both eruptive and intrusive LIP events and better chronologies from extinc- tion and climate proxy records will be required to further understand how these catastrophic volcanic events have changed the course of our planet’s surface evolution. -

Enciclopedia Astronómica
INTRODUCCIÓN El Universo, una realidad en continua evolución. Nuestra visión del Universo ha cambiado de aspecto durante el último cuarto de siglo. Hasta la década de los cincuenta, todo lo que sabíamos del espacio que nos rodea nos llegaba a través de la información contenida en la luz de los astros y, por lo tanto, sólo de las observaciones con telescopio. Asomándose a lo que los astrónomos llaman la ventana óptica de nuestra atmósfera, ese corredor a través del cual pasan las radiaciones visibles del espectro electromagnético, ya era posible observar un panorama gran- dioso y desconcertante. Un inmenso vacío en el cual, como islas en un océano sin límites, flotaban miríadas de galaxias contenien- do cada una miles de millones de estrellas. Nuestro Sol no es más que una de las innumerables estrellas situadas en la periferia de una de las muchas galaxias; y el cortejo de planetas que giran a su alrededor, granitos de polvo en el conjunto del Universo. Des- pués de la primera revolución astronómica llevada a cabo por COPÉRNICO, KEPLER, GALILEO y NEWTON, surge lo que algunos cientí- ficos señalan como la segunda revolución astronómica, con una nueva serie de inventos y descubrimientos, y que aún está en plena evolución. Con ella, el cuadro se ha modificado de manera profunda, definiendo contornos y detalles que pueden tildarse de apa- sionantes. Hoy parece haberse establecido el momento en que nació el Universo, una gigantesca explosión, pintorescamente deno- minada Big Bang, cuyo eco aún vibra en los espacios bajo la forma de una radiación fósil a 3 K. -

His great-grandfather, Isaac, was Postmaster-General in Ireland, and grandfather, John (died 1743), was a Commissioner for Customs and lived at Hatton Garden. His father, also John (c1716-1801), was called to the Bar in 1739 and became a Bencher [senior member] of the Middle Temple in 1768. In 1750 he married Ann Hammond and they had five children. Isaac George Manley. Baptised St Giles-in-the-Fields, London, 3 March 1755. Given high infant mortality rates, most children were baptised quickly and Isaac would have been born about this date. -
The Story of Rupert T Gould – the Flawed Genius Who Rediscovered the Harrison Sea Clocks
Restoration The story of Rupert T Gould – the flawed genius who rediscovered the Harrison sea clocks Timothy Treffry Time Restored Until the publication of Dava Sobel’s phenomenal bestseller Longitude, in 1995, By Jonathan Betts the name and achievements of John Harrison were known only to a small band Oxford University Press and the of horological devotees. Longitude struck a chord though, and was followed by National Maritime Museum, 2006 two films for television and later a stage play. In the major film made by Charles Hardback, 14.5 cm x 22 cm Sturridge for Granada in 1999, Michael Gambon produced a remarkable 480 pages performance as John Harrison, but his story was also interwoven with that of Price: £35 Jeremy Irons' character, Lt Commander RT Gould – a complex figure credited with ISBN 0-19-856802-9 the rediscovery and restoration of Harrison’s sea clocks. The story of polymath and horologist Rupert Thomas Gould (1890–1948) has now been retold in a painstakingly researched and beautifully written biography by Jonathan Betts, Curator of the Harrison timekeepers at the Royal Observatory in Greenwich. Time Restored is subtitled The Harrison timekeepers and RT Gould, the man who knew (almost) everything, and there is a lot of meat, even in the title. At one level, ‘Time Restored’ refers simply to Gould’s work on the timekeepers, but the book also presents a great deal of social history and we are given a (not always edifying) picture of upper middle-class, late Victorian, Edwardian, and mid 20th century life. The subtitle refers to Gould’s performances on the classic BBC radio programmes: Children’s Hour and Brains Trust. -

Lunar Bases and Space Actmties of the 21St Century (1986)
10 / SOCIETAL ISSUES STABLISHING A PERMANENTLY MANNED BASE on the Moon is, of necessity, a large and visible exercise of engineering and technology. Some Ewill see no more than that, but such a reductionist viewpoint misses the whole that is greater than the parts. A lunar settlement continues humanity's movement to accessible frontiers. It may start as a statement of national resolve or as a monument to international cooperation.It could be an heroic enterprise of epic dimensions or the stimulus for democratization of space through economic growth. One thing is clear-the Moon sits on the lip of the confining terrestrial gravity well and thus is the stepping stone to the solar system. The space program blends a curious mixture of romance and pragmatism. Goals are set by dreamers and implemented by realists. Many of yesterday's visions have been realized,but the awe-inspiring accomplishments rest on carefully executed, often mundane contributions from tens of thousands of people. The inspirational and the commonplace are both aspects of the human condition to be reflected in the space activities of the 2 1st Century, and both are discussed in the contributionshere. Any grand achievement by society must begin as an expression of the ordinary processes of decision making. Logsdon, an experienced observer of the space program, looks at the initiation of past endeavors for clues to the key elements of consensus. The debate over allocation of public resources revolves around the worth and expense of any program. Sellers and Keaton analyze historical space expenditures in terms of the gross national product of the U.S.and predict the availabilityof fbnding for major ventures over the next two decades. -
