Book Description
Updated 2024 edition of the most popular book on the riddle of the incredible Siberian explosion of 1908, The Mystery of the Tunguska Fireball, first published in 2005. At about 7:15 a.m. on June 30, 1908, a massive fireball exploded in the skies over Siberia. With force a thousand times greater than the Hiroshima atomic bomb, it levelled over 2,000 square kilometres of the remote Tunguska forest-an area larger than metropolitan London-sending a mushroom cloud towering into the stratosphere. What was it? A wayward black hole, a crashing comet, a rogue asteroid, an exotic rock of antimatter or mirror matter, a methane gas blast from below, an alien spacecraft, a laser beam fired by extraterrestrials, or an early experiment in nuclear physics that got out of hand? Nearly a century and a quarter on, this grand dame of science mysteries still fascinates scientists and charlatans alike. Whichever way you look, the Tunguska event is a captivating journey in serious science, speculative science and science fiction. This informative and engaging book invites you to explore that journey and perhaps glimpse the truth behind this enigmatic explosion. Surendra Verma is a journalist and author based in Melbourne, Australia, since 1970. He has published numerous popular science books in Australia, the UK and the US, and his books have been translated into 14 languages other than English.

Book Description
On 30 June 1908 a mysterious fireball exploded in the Siberian sky and flattened 2,000 square kilometres of the remote Tunguska forest. As no crater and no material from outer space were ever found, a meteorite could not have caused the Tunguska explosion. So what did? This 'grand dame of science mysteries' soon turns 100 but continues to seduce scientists and charlatans alike, all hoping to explain what caused the explosion. The scientists' suspects include a comet, an asteroid, a mini black hole, a rock of antimatter, a mirror matter asteroid, and a methane gas blast from below. X-files-type explanations include an alien spacecraft, a laser beam fired by extraterrestrials in an attempt to communicate with the earthlings, and an early experiment in nuclear physics which got out of hand. Numerous websites, conspiracy theories and sensational TV documentaries on the Fireball abound. In a fast-moving and non-technical narrative The Tunguska Fireball discusses all theories and then analyses the evidence to point an accusing finger at a prime suspect.

Book Description
This riveting work of investigative reporting and history exposes classified government projects to build gravity-defying aircraft--which have an uncanny resemblance to flying saucers. The atomic bomb was not the only project to occupy government scientists in the 1940s. Antigravity technology, originally spearheaded by scientists in Nazi Germany, was another high priority, one that still may be in effect today. Now for the first time, a reporter with an unprecedented access to key sources in the intelligence and military communities reveals suppressed evidence that tells the story of a quest for a discovery that could prove as powerful as the A-bomb. The Hunt for Zero Point explores the scientific speculation that a "zero point" of gravity exists in the universe and can be replicated here on Earth. The pressure to be the first nation to harness gravity is immense, as it means having the ability to build military planes of unlimited speed and range, along with the most deadly weaponry the world has ever seen. The ideal shape for a gravity-defying vehicle happens to be a perfect disk, making antigravity tests a possible explanation for the numerous UFO sightings of the past 50 years. Chronicling the origins of antigravity research in the world's most advanced research facility, which was operated by the Third Reich during World War II, The Hunt for Zero Point traces U.S. involvement in the project, beginning with the recruitment of former Nazi scientists after the war. Drawn from interviews with those involved with the research and who visited labs in Europe and the United States, The Hunt for Zero Point journeys to the heart of the twentieth century's most puzzling unexplained phenomena.

Book Description
Recent planetary missions by NASA, the European Space Agency, and other national agencies have reaffirmed that the geological processes which are familiar from our studies of Earth also operate on many solid planets and satellites. Common threads link the internal structure, thermal evolution, and surface character of both rocky and icy worlds. Volcanoes, impact craters, ice caps, dunes, rift valleys, rivers, and oceans are features of extra-terrestrial worlds as diverse as Mercury and Titan. The new data reveal that many of the supposedly inert planetary bodies were recently subject to earthquakes, landslides, and climate change and that some of them display active volcanism. Moreover, our understanding of the very origins of the solar system depends heavily on the composition of meteorites from Mars reaching the Earth and of rock fragments found on the Moon. Planetary Geology provides the student reader and enthusiastic amateur with comprehensive coverage of the solar system viewed through the eyes of Earth scientists. Combining extensive use of imagery, the results of laboratory experiments, and theoretical modeling, this comprehensively updated second edition (previously published in paperback and now available in hardback) presents fresh evidence that, to quote the first edition, planetary geology now embraces conventional geology and vice versa. *** " . . . a much improved version of what was already a good book. The new text is some 20 percent longer . . . color illustrations have been dispersed throughout . . . and the information presented is brought right up to the minute with numerous injections of new scientific results from the many space missions that have been conducted since the first edition appeared. Recommended." - Choice, Vol. 51, No. 07, March 2014~

Book Description
Marco Altamirano critiques the modern concept of nature to chart a new trajectory for the philosophy of nature. He reveals the modern origins of the epistemological configuration of nature, where a subject confronts an object in space (and at time t), and wonders about her mode of access to that object. After critiquing the spatial orientation of this concept of nature, Altamirano shows that a new concept of time is necessary to reinstall the subject within its concrete ecology. Altamirano goes on to deploy conceptual resources excavated from Deleuze, Guattari, Foucault and Leroi-Gourhan to show how technology, which bypasses the nature-artifice distinction, is an essential dimension of the philosophy of nature. Ultimately, this book draws the profile of a concept of nature based on time and technology that escapes the nature-artifice distinction that has mired the philosophy of nature for so long.

Book Description
‘Incoming Asteroid!’ is based on a project within ASTRA (the Association in Scotland to Research into Astronautics) to provide scientific answers to the question – what would we do if we knew there was going to be an asteroid impact in ten years’ time or less? Clearly there are many things humanity can do nothing about, for example an unseen object traveling towards us so fast that we have no time to prepare, or an object so large it may be unstoppable. A realistic hazard model was decided upon, and the scenario developed from that: an incoming object about 1 kilometer in diameter, in an orbit ranging from the outer rim of the Asteroid Belt to within that of Earth’s. Three basic possibilities are considered in this book. The first is the deflection of the asteroid, using remote probes along with a number of possible technologies to change the asteroid’s course. Second is the attempt of a manned mission, in order to plant a propulsion system on the asteroid to push it into a different orbit. Third is the nuclear option, a last-ditch attempt to break up and then disperse the asteroid using nuclear weapons. (A rather impractical combination of these second and third options were used as the plot of the popular 1998 Bruce Willis feature film, Armageddon.) Although the cost of developing the technology needed to protect the Earth would be substantial, there would certainly be spin-off benefits. These could eventually result in practical small-scale atomic energy sources, new propulsion systems that could make extraterrestrial mining within the solar system a possibility, and other as-yet unforeseen benefits. And finally, Incoming Asteroid! considers the political implications - how governments across the world should best react to the threat with a view to minimizing loss of life, and in the weeks running up to the possible impact, preventing panic in the population.
