Venus and How to Terraform it by Steve Hurley (2 Reviews) Price verified 6 hours ago

The planet Venus is our nearest neighbour, the planet closest to the Earth in size and internal composition, and the brightest natural object in the sky after the Sun and the Moon. Often called Earth's sister planet, Venus is a mysterious object whose secrets were not unlocked until the 1960s. The first chapter focuses on how Venus appears from Earth. The 584-day cycle where Venus goes through a full set of phases like the Moon is explained in detail. The fact that Venus's phases can only be explained by a heliocentric theory and not the geocentric theory, something which was very important to the development of astronomy, is discussed. I then talk about the early depiction of Venus in 1950's science fiction as a world on which exotic life forms could survive. However, exploration of the Venus by spacecraft, discovered a harsh hostile world, where the surface temperature is nearly five hundred degrees Celsius and the atmospheric pressure is a crushing 92 times that of Earth. Despite this I will argue later in the book that it is possible to terraform the planet to make it more Earth-like and may be desirable to do so. I discuss the 'transit of Venus', an astronomical event in which Venus appears to cross the surface of the Sun. Observations of the transit of Venus were critical to the development of astronomy in the seventeenth and eighteenth centuries. The remainder of the book discusses what humans would need to do to live on Venus. The idea of 'floating cities' is discussed and terraforming is explored in detail and how the challenges posed by such a hostile environment could be overcome.

Biodiversity of Angola: Science & Conservation: A Modern Synthesis
by Brian J. Huntley
*(Springer) *
(1 Review)
Price verified 10 hours ago

This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Mayan Calendar Prophecies| Part 2: 2012-New Age of Disasters
by Gary C. Daniels
*(TheRealMayanProphecies.com) *
(10 Reviews)
Price verified 13 hours ago

Mayan prophecies predicted the return of Kukulkan, a green "sky serpent" associated with death and destruction especially floods and severe storms, between the years 1993-2012. Coincidentally, in August 2004 a new green comet was discovered and named Comet Machholz. Since the return and discovery of Comet Machholz in August 2004 Earth has experienced some of the most severe storms, earthquakes, and tsunamis in recorded history. Some of the most severe space weather including the most powerful solar flares and gamma ray bursts in recorded history also occurred since 2004. That year also had the most naked-eye visible comets ever recorded which suggests an increase in the amount of space debris entering the solar system thereby increasing the odds of an impact with Earth. It was also in 2004 that NASA scientists discovered the asteroid Apophis was on a collision course with Earth. Climate scientists have predicted that due to global warming these severe weather events will only get worse in the future. Space weather scientists say the sun appears to have entered a new period of increased activity. Geologists have noted there has been an increase in major earthquakes along the Pacific Plate since 2004 and they also expect more of the same in the future. Comet Machholz was determined to have a 12,500 year orbit. The last time it visited Earth was in 10,500 BC. Scientists have noted that an unimaginable series of disasters struck Earth at that time that included severe climate change, super solar storms and massive flooding. The causes are still debated but what is clear is that these disasters resulted in the extinction of the woolly mammoths, sabre tooth tigers and other Ice Age megafauna. Is this all a coincidence or are these events part of a natural, predictable cycle that happens every 12,500 years and just so happens to correspond with the orbit of Comet Machholz? Were the ancient Maya aware of this cycle and did they encode it in their myths about the ...

Scar Tail the Platypus by Steve Challis (21 Reviews) Price verified 10 hours ago

Scar Tail the Platypus Platypuses were hunted to extinction in South Australia about a hundred years ago. When a platypus escapes from the sanctuary he's attempting something very dangerous with the odds stacked against him. Scar Tail is a male Platypus compelled to seek new territory and leaves the predator proof fences of the sanctuary he was born in and tries to survive in the River Onkaparinga where Platypuses have been extinct for a hundred years. Peter is an autistic boy who has trouble relating to most people, but loves wild places and wild animals. Peter and his only friend, Andrew, save Scar Tail from two Foxes, and observe the recolonization of the valley by wild Platypuses over the next 15 years. Just as Peter helps Platypuses when he can, the Platypuses provide Peter with the stimulus he needs to fulfill his potential. A story with accurate, carefully researched facts about Platypuses and other animals. This is a book about Platypuses and other animals. The animals act like animals, not like people or toys. This is a fictional account of the recolonization of the Onkaparinga Valley in South Australia by Platypuses; a process that has already started in reality. This story was intended for older children and young adults, but I hope adults will also enjoy it and learn a bit about a very unusual animal.

Heat Recovery Steam Generators: Thermal Design & Testing by D. James Benton Price verified 18 hours ago

Heat recovery steam generators (HRSGs) are an integral part of any modern combined cycle power plant. These heat exchangers are designed to recover the heat from a gas turbine exhaust and convert this to steam, which drives a turbine and ultimately a second generator. Because the gas turbine operates efficiently at high temperatures and heat is removed down to nearly ambient temperature, the overall efficiency of this complex design exceeds that of conventional Rankine cycle coal-, oil-, or gas-fired systems. These systems can also be operated in simple or combined cycle, increasing flexibility and response to load dispatch. HRSG can be complex to analyze and also difficult to effectively test and prove their performance. This text covers both theory and testing in practice with examples.

This book covers how each and everyone of us comes to believe what makes up our store of knowledge - what's real or true and what's not and why the difference is critically important to mankind. It progresses from mythological creation myths, superstitions, to "New Age" beliefs, to a summary of the countless gods of the past and then examines some of the religions that are common today. The beliefs that under-lie these religions are covered and much of that content will surprise some. Topics covered in that progression include Communicating with the dead, No touch knockdowns and so-called Faith healers, many of which are illustrated by links to videos. The importance of critical thinking and the lack of it in many of these areas leads to problems that are harmful, to put it mildly. Heavy emphasis is placed on reviewing the variety of religions and their distribution around the world. The text contains a rich library of links to more material. We then move on to discuss some of the Holy books including the Bible, Prayer and Miracles, Marriage, Abortion, Contraception and Homosexuality. Other topics include why people are increasingly abandoning religions, the separation of Church and State and we address the question - Is America a Christian Nation? The benefits and downsides of religion are discussed and that leads to another question - Would the World be Better without Religion? Heading toward the end purpose of this book, namely what are Humankind's Best and Worst Concepts we ask - Are Science and Religion Compatible or in conflict? and there we cover Evolution, the Origin of Life and the Universe, some of the notable accomplishments of science and end with an almost inescapable conclusion.

The Secret Behind the Universe: Cosmology in Vedanta: The Physics Correlation
by C Radhakrishnan
*(Hi-Tech Books) *
(39 Reviews)
Price verified 14 hours ago

This is the free e-book of the famous work 'The Secret Behind the Universe' by the same author. Exploring the secrets of the Universe as far as physics can go, and even beyond.. Along with its Vedantic integration. This book is divided into two sections. The first section is a work in physics which presents an in-depth exploration of Avyakta - the hidden metaphysical reality behind the apparent universe - through scientific study. A condensed version of this part has been published in the Prespacetime Journal Vol 7 Issue 16 on 08/01/2017, titled "Avyakta - The Fabric of Space" in which this concept is explored to complement the Standard Model and explain gravitation. This section of the book attempts to explore the role of avyakta behind various phenomena like matter waves, energy in the vacuum state, spiral arms of galaxies, dark matter, Higgs boson and virtual particles which pop out of nowhere, big bang and cosmic inflation and the anti-particle. (Prespacetime Journal (ISSN: 2153-8301), QuantumDream, Inc., P.O. Box 267, Stony Brook, NY 11790-0267, USA; is a physics journal which focuses on the origin, nature and mechanism of space-time and its possible connection to a prespacetime; and models and experimental results on elemental particles, fundamental forces including gravity and related topics.) The second section of the book presents in-depth study of cosmology as outlined in ancient Indian Philosophy, researching from the Bhagavad Gita and the Upanishads. The discussions shed light on many previously unknown levels and aspects. Since God cannot be considered in physics due to lack of experimental evidence, this section is provided as a separate part! The first book of its kind, it brings the diverse fields of Science and Philosophy into face-to-face contact. It is a thrilling journey for all types of readers interested in science or Vedanta.
