Please Explain


Karl Kruszelnicki
    avoid opinion ... facts are your single clue. Get the facts!' - time Enough for Love, Robert Heinlein Does eating celery make you lighter? Do you have to be dying to have a near-death experience? Is a yawn a silent, natural scream for air; and if a little oxygen is good for you is more oxygen better? Can the humble spud kill? Did Galileo drop his balls from the Leaning tower of Pisa? Did a NASA computer really prove a miracle in the Bible actually happened? Is there any substance harder than diamond, and do diamonds really last forever? And exactly how many Eskimo words for 'snow' are there? Wherever he goes, people always ask Dr Karl to explain stuff, and in this his 26th book (26 is the only number directly between a square and a cube), he explains more myths and curly questions.

Astronomy


Andrew Fraknoi - 2012
    The book begins with relevant scientific fundamentals and progresses through an exploration of the solar system, stars, galaxies, and cosmology. The Astronomy textbook builds student understanding through the use of relevant analogies, clear and non-technical explanations, and rich illustrations. Mathematics is included in a flexible manner to meet the needs of individual instructors.

Life in the Universe: Essays


Carl Sagan - 1998
    These unabridged essays by Carl Sagan were originally published in either popular science magazines or academic journals. This is the first time his essays have become available on audio.

Time-Saver Standards for Housing and Residential Development

    In superb graphic detail, with hundreds of plans, illustrations, and diagrams, this comprehensive resource presents and entire library's worth of essential design data for residential development.

Ripples in Spacetime: Einstein, Gravitational Waves, and the Future of Astronomy


Govert Schilling - 2017
    Einstein predicted these tiny ripples in the fabric of spacetime nearly a hundred years ago, but they were never perceived directly until now. Decades in the making, this momentous discovery has given scientists a new understanding of the cataclysmic events that shape the universe and a new confirmation of Einstein's theory of general relativity. Ripples in Spacetime is an engaging account of the international effort to complete Einstein's project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe's structure and origin.The quest for gravitational waves involved years of risky research and many personal and professional struggles that threatened to derail one of the world's largest scientific endeavors. Govert Schilling takes readers to sites where these stories unfolded--including Japan's KAGRA detector, Chile's Atacama Cosmology Telescope, the South Pole's BICEP detectors, and the United States' LIGO labs. He explains the seeming impossibility of developing technologies sensitive enough to detect waves from two colliding black holes in the very distant universe, and describes the astounding precision of the LIGO detectors. Along the way Schilling clarifies concepts such as general relativity, neutron stars, and the big bang using language that readers with little scientific background can grasp.Ripples in Spacetime provides a window into the next frontiers of astronomy, weaving far-reaching predictions and discoveries into a gripping story of human ambition and perseverance.
