Hidden attraction : the history and mystery of magnetism by Gerrit L Verschuur( )

29 editions published between 1993 and 1996 in English and held by 2,702 WorldCat member libraries worldwide

Long one of nature's most fascinating phenomena, magnetism was once the subject of many superstitions. Magnets were thought useful to thieves, effective as a love potion, or as a cure for gout or spasms. They could remove sorcery from women and put demons to flight and even reconcile married couples. It was said that a lodestone pickled in the salt of sucking fish had the power to attract gold. Today, these beliefs have been put aside, but magnetism is no less remarkable for our modern understanding of it. In Hidden Attraction, Gerrit L. Verschuur, a noted astronomer and National Book Award nominee for The Invisible Universe, traces the history of our fascination with magnetism, from the first discovery of magnets in Greece, to state-of-the-art theories that see magnetism as a basic force in the universe. The book begins with the early debunking of superstitions by Peter Peregrinus (Pierre de Maricourt), whom Roger Bacon hailed as one of the world's first experimental scientists (Peregrinus held that "experience rather than argument is the basis of certainty in science"). Verschuur discusses William Gilbert, who confronted the multitude of superstitions about lodestones in De Magnete, widely regarded as the first true work of modern science, in which Gilbert reported his greatest insight: that the earth itself was magnetic. We also meet Hans Christian Oersted, who demonstrated that an electric current could influence a magnet (Oersted did this for the first time during a public lecture) and Andre-Marie Ampere, who showed that a current actually produced magnetism. Verschuur also examines pioneering experiments and theoretical break-throughs of Faraday and Maxwell and Zeeman (who demonstrated the relationship between light and magnetism), and he includes many lively stories of discovery, such as the use of frogs by Galvani and Volta, and Hertz's accidental discovery of radio waves. Along the way, we learn many interesting scientific facts, perhaps the most remarkable of which is that lodestones are made by bacteria (a sediment organism known as GS-15 eats iron, converting ferric oxide to magnetite and, over billions of years, forming the magnetite layers in iron formations). Boasting many informative illustrations, this is an adventure of the mind, using the specific phenomenon of magnetism to show how we have moved from an era of superstitions to one in which the Theory of Everything looms on the horizon
Impact! : the threat of comets and asteroids by Gerrit L Verschuur( )

25 editions published between 1996 and 1998 in English and held by 2,379 WorldCat member libraries worldwide

In Impact, Gerrit L. Verschuur offers an eye-opening look at catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility. Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year mostly in meteoric form. But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth
The invisible universe; the story of radio astronomy by Gerrit L Verschuur( Book )

42 editions published between 1974 and 2015 in English and Undetermined and held by 1,762 WorldCat member libraries worldwide

Hidden from human view, accessible only to sensitive receivers attached to huge radio telescopes, the invisible universe beyond our senses continues to fascinate and intrigue our imaginations. Closer to home, in the Milky Way galaxy, radio astronomers listen patiently to the ticking of pulsars that tell of star death and states of matter of awesome densities. All of this happens out there in the universe hidden from our eyes, even when aided by the Hubble Space Telescope. This is the story of radio astronomy, of how radio waves are generated by stars, supernova, quasars, colliding galaxies and by the very beginnings of the universe itself. The author discusses what radio astronomers are doing in the New Mexico desert, in a remote valley in Puerto Rico, and in the green Pocahontas Valley in West Virginia, as well as dozens of other remote sites around the world. With each of these observatories, the scientists collect and analyze their data, "listening" to the radio signals from space in order to learn what, or perhaps who, is out there as well. The author specifically highlights enormous changes that have occurred in the field over the past 50 years, including the political reality of radio astronomy and what that could mean for the future

Galactic and extra-galactic radio astronomy by Gerrit L Verschuur( Book )

43 editions published between 1974 and 2012 in 3 languages and held by 725 WorldCat member libraries worldwide

The present set of chapters by members of the staff of the National Radio Astronomy Observatory deals with the basic fields of research concerned with radio astronomy outside the solar system. The emphasis in this volume is on the type of data available and its interpretation. Basic theory is considered only where absolutely necessary, and little discussion of receivers or techniques is entered into in most of the chapters. The book is intended to take over where most textbooks on radio astronomy leave off, that is, in the discussion of what is actually known from the research done. In addition there is a chapter on the technical aspects of inter ferometry and aperture synthesis, since so much of modern radio astronomy depends, and will depend in an ever increasing manner, on such tools. The editors want to stress that the chapters were not necessarily expected to be compre hensive reviews of any of the fields being covered, but rather, overall outlines which the in dividual authors feIt would be suitable for graduate students and interested workers in other fields. As a result, the lists of references are not complete. This only refiects the preferences of the individual authors and not the relative merit of those references incIuded or omitted
