Look Again
The brain, when you first expose it, is silent.A consultant neurosurgeon has stood at that threshold hundreds of times. The dura opened, the cortex fully visible, the instruments reading everything they were built to read. And yet the thing that matters most remains somewhere they cannot reach. The story only emerges when you create the conditions for consciousness to speak.Mohamed Abdalla recognised, at that threshold, that physics stands in exactly the same position before the universe. The science is not wrong and the readings are real. But maximum exposure is not the same as understanding, and the silence that remains after every measurement is not empty.Look Again is his attempt to create the conditions for what the silence contains.It began with a question he could not answer. A man at Speaker's Corner in Hyde Park, a convinced atheist who had thought carefully about these things, asked how a neurosurgeon could believe what Islam asks its adherents to believe. The question was not hostile. It deserved a serious answer. This book is that answer.The question belongs to no single tradition. Every serious believer in a scientific age has stood at that boundary. This book stands there too, and answers it from within the Islamic tradition of tafakkur: sustained contemplative reflection on the signs of creation, bringing modern cosmology, classical theology, Quranic linguistics, and Sufi metaphysics into genuine conversation, each speaking from its own register, none collapsed into the others.The journey the book traces moves from the first moment of creation to its last, and from the outermost structure of the heavens to the ground beneath a forehead in prostration. At every point, the question is the same: what does this disclose, if you look carefully enough?Its position is neither that faith must accommodate science nor that science threatens faith. It is that honest inquiry, pursued far enough, arrives at the boundary where revelation begins, and that standing at that boundary with both modes of knowing fully alive is precisely where the Quran invites its reader to stand.This is a book for anyone who has taken the findings of science seriously and felt, at their edge, that the silence was not empty.

The Conscious Cosmos
What if consciousness is not a late glitch in an otherwise empty cosmos, but the very medium in which everything unfolds? This book invites you to reconsider the universe you thought you lived in, exploring the daring possibility of a conscious universe and a truly universal consciousness. Moving between cosmology, philosophy, and contemplative insight, it offers a clear, grounded tour of panpsychism explained for thoughtful readers. Along the way, it reframes the classic puzzles of philosophy of mind, asking whether a spiritual cosmology can sit comfortably beside hard-won scientific knowledge. Rather than forcing agreement, it holds science and spirituality in creative tension, showing how each can correct the other's blind spots. You will encounter accessible arguments for awareness as fundamental, reflections on the nature of reality, and fresh ways to think about mind and matter as intertwined rather than opposed. Simple practices help you test these ideas in your own experience, linking the vastness of the sky to your most intimate inner and outer worlds. This book is for sceptical seekers, spiritually curious scientists, and anyone who feels that neither tidy materialism nor rigid dogma quite fits. If you want a rigorous yet open-hearted guide to the possibility of a living universe, this is your next conversation partner.

The Riddle Of The Universe At The Close Of The Nineteenth Century
The riddle of the universe at the close of the nineteenth century examines the evolving relationship between scientific inquiry and philosophical thought. It highlights the rise of empirical understanding in fields like biology and cosmology while pointing to a contrasting stagnation in moral and spiritual perspectives. Drawing on natural laws, evolutionary processes, and material structures, it argues for a unified explanation of existence rooted in observable phenomena. The work introduces the idea of world riddles deep questions about life, mind, and the cosmos that challenge fragmented or mystical interpretations of reality. It promotes a monistic framework that sees all physical and mental forms as expressions of a singular substance, eliminating dualistic divisions between body and spirit. This approach combines scientific reasoning with existential curiosity, encouraging reflection on the continuity of nature and human consciousness within it. Rather than isolate disciplines, it advocates for an integrated view of knowledge that reshapes how existence, identity, and purpose are understood at a pivotal point in intellectual history.
Thunder in the Heartland
Ohio can be a land of weather extremes. There are droughts followed by flood, arctic cold and soaring heat in one year, a Christmas warmed to 70 degrees and a Christmas white with thirty inches of snow. Ice jams on the Sandusky River and tornadoes across its southern counties, wind storms in Cleveland and floods in the Ohio River Valley inspire Ohioans to "remember when." Thomas and Jeanne Schmidlin, native Ohioans, have brought together data from government records, scientific studies, memoirs, diaries, and newspapers in the first comprehensive book on Ohio weather. They highlight 200 weather events from 1790 to the present--extremes of rain, snow, storms, and temperature. Anecdotal, often first person, accounts are enhanced by statistics, photographs, and maps. They describe the place of weather in popular history and folklore and how forces of nature compelled the construction of extensive flood control and weather warning systems in Ohio. Thunder in the Heartland will be of interest to climatologist, cultural historians, and all who live the weather of the Oho Country.
Total Theories of Things and Life
What is the origin of anything? What does it mean to look up to the sky and see the stars? What does it mean to be, even when we do not know it? What lies beyond the partial explanations we accept as truth? Some of life's biggest questions cannot be solely solved by experiments or equations alone. They live in the realm of theory, where physics, psychology, and philosophy meet to imagine what reality might be -something different to each observer.This book explores ideas that stretch beyond proof: a looped universe, the inaccessible areas of the mind and our behavior, a philosophical exploration of the paradoxical nature of human actions, and the interplay between body and cosmos. Understanding why we cannot perceive everything, why our evolutionary progress is limited by our own restrictions, and how our actions can be both right and wrong at once.Rather than offering final answers, it lays a foundation and an intertwined framework of possibilities that, when interpreted, may point toward a deeper understanding. An invitation to see existence in new and unexpected ways, potentially propelling thinking beyond general norms while serving as a "partial theory of a lot".
UFO Disclosure
The UFO phenomenon will simply not go away. It is here to stay. Recent moves by former intelligence personnel to disclose what they know about the UFO reality has catapulted the subject into the mainstream media.The stigma attached to this topic has gone. It is now taken seriously in official circles, but the disclosure process is much more complex and wide-ranging than is currently portrayed. It is of such significance that it is impacting upon the way we understand our place as humans, not just here on planet earth, but within a much larger reality. The links to that reality have for the most part been forgotten by many on this planet.The UFO disclosure process has the potential to liberate human consciousness from the shackles imposed upon it for millennia. This can only happen if we fully come to terms with what we mean by UFO disclosure in the 21st Century. UFO Disclosure: Forgotten Links takes us a few steps further in that process of liberation.

The Spirit of Stone
From the lonely heights of mountains to the womblike depths of caves, stone has always drawn us in. In The Spirit of Stone, Wyl Menmuir explores the many ways in which rock and earth form part of our identities, histories, and futures. Across Britain and Ireland, rock is everywhere beneath our feet, shaping not only our landscapes but also our imaginations and the ways we live together. Moving across these lands, Wyl Menmuir's essays combine travelogue, social history, and memoir, bringing together interviews, folklore, and personal encounters with the landscapes themselves. From sacred monuments to modern sculpture, this book reveals how stone grounds us, challenges us, and inspires us, such as: Mountains and caves as places of pilgrimage, danger, refuge, and wonder. Ancient pathways andstone circles that leave traces of our ancestors written into the land. Marks and monuments, from Neolithic carvings to contemporary sculpture, art that endures across centuries. Everyday stone, for example the quarries, buildings and raw materials that underpin our daily lives. The Spirit of Stone follows on from The Draw of the Sea and The Heart of the Woods, completing a trilogy of explorations into our relationship with place. Where the first two books took readers to the water's edge and into the forest, this book journeys into the landscapes of rock, stone and earth, reflecting on how they continue to define us. Resonant with the work of Robert Macfarlane, Kathleen Jamie and Peter Ross, yet strikingly original in its breadth and vision, The Spirit of Stone is a profound meditation on belonging, endurance, and our shared human story written in stone.
Ripple Centrism
For centuries, humanity has redrawn its map of the cosmos. Ptolemy placed Earth at the center. Copernicus shifted the focus to the Sun. Newton transformed the heavens into a clockwork of forces, and Einstein bent space and time into a fabric of relativity. Each of these revolutions overturned certainty, each carried paradoxes, and each left cracks that demanded the next correction.Now comes the third revolution.In Ripple Centrism: From Copernicus to Chavan, Sandeep Chavan challenges the very foundation upon which modern science rests: motion itself. What if the universe is not in motion at all? What if day and night, the seasons, eclipses, and even the waxing of the Moon are not consequences of spinning or orbiting bodies, but of ripple alignments in a still, structured substrate?Drawing from decades of independent research and teaching, Chavan introduces Universal Energy Dynamics (UED) - a framework where stillness, not motion, is fundamental. Here, every phenomenon we call matter, energy, light, or time arises from the disturbance and resolution of equilibrium: Day and night without Earth's rotation.Seasons without axial tilt.Eclipses without shadows.Light as ripple-release, not photon travel.Time as Alignment Threshold Time (ATT) - delay, not dimension.With clarity and boldness, Chavan reframes long-accepted cosmological truths. Dark matter, dark energy, and spacetime curvature appear not as ultimate realities, but as patches invented to defend a motion-first worldview. In their place, Ripple Centrism offers a cosmos of stillness - experimentally testable, philosophically consistent, and startlingly aligned with perception itself. The Earth feels still because it is still. The Sun seems to move because ripple coherence makes it appear so.This book is not a rejection of science, but an extension of its most daring spirit: the courage to question the unquestionable. It honors the precision of past models while exposing their ontological flaws, offering a new foundation on which future science can stand. Just as Copernicus disturbed the Earth and Einstein disturbed absolutes, Chavan now disturbs motion itself.Accessible yet profound, Ripple Centrism invites scientists, philosophers, students, and seekers alike to join the dialogue. More than a theory, it is a manifesto - declaring that the universe was never centered, never moving, but always whole and still.The Third Revolution in cosmology has begun.
Nightfaring
A heartfeltexploration of the night on Earth, following a travel journalist and dark sky advocate around the globe as she seeks out dark places in our ever-brightening world. People, plants and animals all depend on the natural night--both its darkness and its starlight--for so much, from regulating our sleep cycles to providing the inspiration for myths and legends across the millennia. But darkness is disappearing, and with it, our view of the stars. The constant glow of streetlights, of headlights streaming down highways, and wasteful glare from skyscrapers left shining all night have created so much light pollution that the majority of Americans can no longer see the Milky Way or experience the restful embrace of a natural night. As the dark becomes ever more elusive, it is a critical moment to stop, look up, and consider what we lose with the disappearing stars. In Nightfaring, Megan Eaves-Egenes travels around the world to better understand our deep connection to the dark. Finding solace in the stars at a time of difficulty in her own life, she embarks on a journey from New Zealand to Uzbekistan, Italy to Japan, Germany to the Himalaya, exploring the many ways that humans have depended on, feared, and mythologized darkness. Blending travel and nature writing with history and self-discovery, Megan writes of how the stars have helped her chart the course of her own life--just as they've guided humankind for as long as we've slept beneath them.
Ocean Paths of Discovery
The sea is a perennial source of enchantment, a true labyrinth of beauty, but also a stage for unforeseen and unpredictable changes, often bringing dangers and hardships. There is knowledge that is not only necessary, but essential for those who live, spend hours or use this environment as a source of work. The maritime mentality is a process of building knowledge, awareness and appreciation of the importance of the sea for the survival and prosperity of a nation. This concept involves the collective belief in the vital role of the oceans in the economy, culture and environment. Practices related to the importance of the oceans should become a habit in the nation, especially in its academic meanders, through formal and informal educational experiences, promoting an ocean culture that values marine resources. Sustainable development is connected to the concept of blue economy, which emphasizes the preservation of marine ecosystems and the importance of the oceans for biodiversity and climate. Oceanographic dynamics involves the study of currents, tides and other phenomena that affect the oceans and regulate the Earth's climate. While Magnetic Declination is crucial for cartography and oceanography, as it influences orientation in relation to true north and establishes precision in geographic coordinates. This knowledge is fundamental for carrying out accurate analyses in various areas, such as climatology and ecology, where the interaction between the oceans and the atmosphere plays a vital role in understanding natural phenomena and predicting climate events.
Universe
A sweeping, reflective history of how we've tried to understand the universe. The physical universe is a most peculiar concept, not only different from the objects it contains but also from space itself. Cosmology--the science that seeks to explain it--has always differed from other sciences, drawing on philosophy and even theology. These influences remain, even in today's data-driven cosmological models. This accessible and far-reaching book traces the development of cosmological thought from antiquity to the twenty-first century, with particular focus on the foundational work of Einstein, Hubble, and others in the early twentieth century. It explores how modern theories rest on a surprisingly fragile base and argues that many cosmic mysteries may remain permanently unsolved. Rich in historical and philosophical insight, this is a lucid guide to what we know--and perhaps cannot know--about the universe.
The 1800s
Information about the climate as reported by the mass media is both incomplete and misleading. Climate Change or "Global Warming" is portrayed as a new phenomenon caused almost entirely by human activity. However, a thorough analysis of North America's climate reveal that both warming and increased precipitation have been a long-term trends that are documented since the earliest instrument records begin in the late 1700s. The most important change has been a remarkable increase in precipitation since the early 1900s which has resulted in record agricultural production and prosperity for much of North America. The adverse climate of the 1800s is ignored, forgotten and even denied. This omission seems intentional and calculated because it threatens the idea that the climate was benign in the past but is now deteriorating. An honest analysis of history refutes this claim.
The Runaway Universe
No matter in which direction we look out from our position in space, everything is moving away from us at an ever-increasing rate. The Runaway Universe. It appears as though we are living on the surface of a balloon which is being inflated by the force of the Big Bang which first brought our universe into being. While some scientists believe that the universe will eventually run out of energy and die, others, including the author, suggest another, more exciting possibility. What if this universe is just one incarnation of a continuous series of universes that recycles through a sequence of expansions (Big Bangs) and contractions (Black Holes)? This book expands on ideas developed in Energy and Everything, the first of a three-part series by the author examining recent developments in the fields of particle physics and cosmology. Readers are invited to join the author in some interesting and challenging thought experiments designed to examine what is reality and what is illusion, all smoke and mirrors. Is the universe we live in merely a stage on which we act out our lives, telling our stories in a continuous, never-ending series of stories that join with countless other stories in a book called Life?
The Physics of Faith
The universe is 13.8 billion years old, contains two trillion galaxies, and is heading toward heat death. How can Christians maintain faith in divine purpose within such cosmic immensity and apparent indifference?"The Physics of Faith" offers an honest, profound exploration of the dialogue between modern cosmology and Christian belief. Rather than forcing easy harmonization or accepting inevitable conflict, this book dwells thoughtfully in the creative tension between scientific discovery and religious faith.Drawing on cutting-edge physics and classical theology, the author examines: How spacetime and relativity complicate our understanding of prayer and divine eternityWhy quantum mechanics neither proves nor disproves God, despite popular claimsThe genuine challenge that evolutionary suffering poses to belief in a good CreatorHow fine-tuning might point to design-or to multiple universesWhat dark matter and dark energy reveal about the limits of our knowledgeWhy the heat death of the universe challenges Christian hope for new creationThrough lyrical prose that moves between scientific precision and spiritual reflection, this book speaks to three audiences: scientists who maintain faith despite professional pressures, young Christians encountering cosmology for the first time, and thoughtful believers seeking honest engagement with modern physics.Unlike books that claim science proves God or that faith requires rejecting evolution, "The Physics of Faith" respects both domains while acknowledging real tensions. It includes candid testimonies from working scientists about their struggles to integrate research with faith, a survey of different approaches to science-religion dialogue, and resources for continued exploration.This is not a book of easy answers but of profound questions: Can prayer make sense in a block universe? How does God act in nature without violating physical laws? What does human significance mean at cosmic scales? How do we maintain hope when physics predicts cosmic death?Perfect for book clubs, adult education classes, and individual seekers, "The Physics of Faith" offers a mature, nuanced approach to one of our era's most important conversations. It will challenge believers to take science seriously and scientists to remain open to transcendence, while equipping both for honest dialogue.Written for those who refuse to choose between telescope and scripture, between laboratory and sanctuary, this book models intellectual courage and spiritual depth in exploring how the God of faith might relate to the cosmos of modern science.

Assessment of the Impact of Various Ionospheric Models on High-Frequency Signal Raytracing
An assessment of the impact of various ionospheric models on high-frequency (HF) signal raytracing is presented. Ionospheric refraction can strongly affect the propagation of HF signals. Consequently, Department of Defense missions such as over-the-horizon RADAR, HF communications, and geo-location all depend on an accurate specification of the ionosphere. Five case studies explore ionospheric conditions ranging from quiet conditions to solar flares and geomagnetic storms. It is shown that an E layer by itself can increase an HF signal's ground range by over 100 km, stressing the importance of accurately specifying the lower ionosphere. It is also shown that the GPSII model has the potential to capture the expected daily variability of the ionosphere by using Total Electron Content data. This daily variability can change an HF signal's ground range by as much as 5 km per day. The upper-ionospheric response to both a solar flare and a geomagnetic storm is captured by the GPSII model. In contrast, the GPSII model does not capture the lower-ionospheric response to either event.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Weaponization of Space
It is inevitable that mankind will weaponize space and equally likely that this will take place in the next thirty years. The United States is in the early stages of a transition from using space assets to support combat operations on the surface of the earth to using space assets to conduct combat operations in space, from space, and through space. This paper discusses factors driving the United States to take its first steps to weaponize space. It is time for the Air Force to build the doctrinal framework for combat operations in, from, and through space that will guide the technological development of space assets just as the doctrine of strategic bombardment guided Air Force thought and aircraft development prior to World War II. This paper discusses the transition from an air to a space force by examining required changes to Air Force doctrine in terms of the framework of its six core competencies in order to prepare the Air Force to organize, train, and equip aerospace forces for conducting combat operations in space.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

A Brief History of the Universe (and Our Place in It)
"A sweeping tour of the laws of physics, the scope of the universe, and the place of life within it." --Sean Carroll, New York Times bestselling author of The Biggest Ideas in the UniverseAn elegant exploration of humanity's continuous search to find the hidden truths of the universe and comprehend our place in the cosmos.We have always looked up at the night sky and wondered. Ever since the ancient Babylonians began to track celestial objects on clay tablets, scientific inquiry has been driven by the innate human desire to understand what is out there, and where we fit into it all.Renowned particle physicist Dr. Sarah Alam Malik, whose research has brought her to the cutting edge of scientific advancement, takes us on a journey through the discoveries that have at once propelled and overturned our perception of the cosmos. From Copernicus launching a helio-centric revolution to Ernest Rutherford uncovering the world inside the atom, to Vera Rubin confirming the existence of dark matter, each generation has built upon, and then upended, the knowledge of those who came before.Even today, as ninety-five percent of the universe remains unknown to us, we cannot help but chase the fundamental truths of our world, as we witness the fiery deaths of faraway suns, probe the nature of dark energy and search for extraterrestrial life in the most unexpected places.Beautifully written and accessible, A Brief History of the Universe (And Our Place in It) is a celebration of our story so far, one of discovery and an endless curiosity that has taken us far beyond the boundaries of the world we know.
Behold the Heavens
Do you remember the last time you marveled at the night sky? How long has it been since you gazed in amazement at the stars above and listened to the sacred silence? The night sky offers an experience of awe and wonder, one that for many of us calls back to our childhood. It can also be an opportunity to connect with the creator of the universe and behold his heavenly majesty.Behold the Heavens invites you on a journey of encounter and prayer. This book is a pilgrimage through the night sky, where we meet God through the beauty of his creation, the words of Sacred Scripture, and the call to prayer. This is not a book about definitions of astronomical objects, but an invitation to experience the night sky through biblical eyes and with childlike wonder.As we gaze upon the night sky, we come to stand in awe of God and all that he has made. In doing so, may we draw closer to God and open our hearts to how he is speaking to us.
18th Century Climate of Jamaica Derived from the Journals of Thomas Thistlewood, 1750-1786
Thomas Thistlewood is known for his daily records of life on a slave plantation in eighteenth-century Jamaica. Thistlewood's previously unexamined weather journal is shown here to be the most important written record from the Earth's tropical regions available. His observation methods are superior to most of his contemporaries & provide a high-quality daily record of more than 35 years. Comparison of his records with modern weather records indicates that Thistlewood's Jamaica was a much cooler & moister place than in modern times. A 252-year record of tropical storm & hurricane frequency in Jamaica reveals that the late 20th-century minimum in storm frequency is unprecedented.
Developing Tests of Visual Dependency
Astronauts develop neural adaptive responses to microgravity during space flight. Consequently these adaptive responses cause maladaptive disturbances in balance and gait function when astronauts return to Earth and are re-exposed to gravity. Current research in the Neuroscience Laboratories at NASA-JSC is focused on understanding how exposure to space flight produces post-flight disturbances in balance and gait control and developing training programs designed to facilitate the rapid recovery of functional mobility after space flight. In concert with these disturbances, astronauts also often report an increase in their visual dependency during space flight. To better understand this phenomenon, studies were conducted with specially designed training programs focusing on visual dependency with the aim to understand and enhance subjects ability to rapidly adapt to novel sensory situations. The Rod and Frame test (RFT) was used first to assess an individual s visual dependency, using a variety of testing techniques. Once assessed, subjects were asked to perform two novel tasks under transformation (both the Pegboard and Cube Construction tasks). Results indicate that head position cues and initial visual test conditions had no effect on an individual s visual dependency scores. Subjects were also able to adapt to the manual tasks after several trials. Individual visual dependency correlated with ability to adapt manual to a novel visual distortion only for the cube task. Subjects with higher visual dependency showed decreased ability to adapt to this task. Ultimately, it was revealed that the RFT may serve as an effective prediction tool to produce individualized adaptability training prescriptions that target the specific sensory profile of each crewmember.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Marathon to the Stars
The United States' ever growing reliance on space assets requires a paradigm shift in how the government invests resources to obtain high quality capabilities, and remain ahead of international peers in the global space race. This research paper answers the question, what specific technology investment strategies should the US take to increase its position among the international space powers? Using a problem-solution methodology, an optimum investment strategy is determined and then compared against the current investment approach of the US. The US currently relies heavily on direct government-led funding and development, leveraging very little of the vast commercial potential within the US and international community resulting in high costs, long schedules, and a lack of innovation. This conclusion supports the recommendation that the US must greatly increase the use of commercial assets for space launch, satellite communications, and imagery intelligence, and pursue international cooperation for space exploration.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Dynamic Coupling of Quasi-Electrostatic Thundercloud Fields to the Mesosphere and Lower Ionosphere
Red Sprites and Blue Jets are two different types of recently discovered optical flashes ob- served above large thunderstorm systems. Sprites are luminous glows occurring at altitudes typically ranging from approximately 50 to 90 km. In video they exhibit a red color at their top which gradually changes to blue at lower altitudes. Sprites may occur singly or in clusters of two or more. The lateral extent of "unit" sprites is typically 5-10 km and they endure for several milliseconds. Jets are upward moving (approximately 100 km/s) highly collimated beams of luminosity, emanating from the tops of thunderclouds, extending up to approximately 50 km altitude and exhibiting a primarily blue color. We propose that sprites result from large electric field transients capable of causing electron heating, breakdown ionization and excitation of optical emissions at mesospheric altitudes following the removal of thundercloud charge by a cloud-to-ground discharge. Depending on the history of charge accumulation and removal, and the distribution of ambient atmospheric conductivity, the breakdown region may have the shape of vertically oriented ionization column(s). Results of a two-dimensional and self consistent quasi-electrostatic (QE) model indicate that most of the observed features of sprites can be explained in terms of the formation and self-driven propagation of streamer type channels of breakdown ionization. Comparison of the optical emission intensities of the 1st and 2nd positive bands of N2, Meinel and 1st negative bands of N2(+) and the 1st negative band of O2(+) demonstrates that the 1st positive band of N2 is the dominant optical emission in the altitude range approximately 50-90 km, which accounts for the observed red color of sprites.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Initial Determination of Low Earth Orbits Using Commercial Telescopes
Within the last decade, many new technologies have significantly changed the face of private astronomy. Developments such asinexpensive but high-quality sensors, rapid personal computing, and easy networking inspire a reexamination of an old problem: how practical is it to develop initial orbit estimates for Low Earth Orbiting (LEO) satellites using optical tracking? This paperdocuments the design and implementation of a commercial telescope system used to answer precisely that question. This analysisdetermined there are some challenging barriers to successful single-site orbit determination, but it is possible given the rightconditions. Considering the low cost and small support footprint of such systems, they could provide excellent support to SpaceSituational Awareness (SSA) missions or satellite tracking operations in general.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Mission Analysis and Design for Space Based Inter-Satellite Laser Power Beaming
This research effort develops an interdisciplinary design tool to optimize an orbit for the purpose of wirelessly beaming power from the International Space Station's (ISS) Japanese Experimental Module Exposed Facility (JEM/EF) to a target satellite. For the purpose of this initiative, the target satellite will be referred to as FalconSAT6, a reference to the proposed follow-on satellite to the U.S. Air Force Academy's (USAFA) FalconSAT5 program. The USAFA FalconSAT program provides cadets an opportunity to design, analyze, build, test and operate small satellites to conduct Department of Defense (DoD) space missions. The tool developed for this research is designed to find an optimal solution balancing the need to maximize the amount of access time between the ISS and FalconSAT6 while minimizing the range between the spacecraft. This tool places mathematical rigor to the problem and determines realistic solutions using current technology. Using this tool allows mission planners to economically and accurately predict the outcome of a proposed wireless power beaming mission.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Realities of Images
In Feb. 1877, a letter from the county council of Telha, a town of 600 people located in the Serra da Mattos in Brazil reported that people were dying from starvation. The previous year's rainy season had been sparse, and the harvest, poor. Now, this season's rains still had not appeared. This was the Great Drought -- three years of failed rains enshrined in Brazilian memory as the worst drought ever to hit Brazil's northeast. Drought had visited the region throughout its history, with the earliest recorded occurrences dating back to the 16th century. The failure of rains in 1877 was devastating, for it caught the provinces of the north totally unprepared. The specter of periodic droughts producing dislocation and death continues to haunt the region.

MACS, An Instrument and a Methodology for Simultaneous and Global Measurements of the Coronal Electron Temperature and the Solar Wind Velocity on the Solar Corona
In Cram's theory for the formation of the K-coronal spectrum he observed the existence of temperature sensitive anti-nodes, which were separated by temperature insensitive nodes, at certain wave-lengths in the K-coronal spectrum. Cram also showed these properties were remarkably independent of altitude above the solar limb. In this thesis Cram's theory has been extended to incorporate the role of the solar wind in the formation of the K-corona, and we have identified both temperature and wind sensitive intensity ratios. The instrument, MACS, for Multi Aperture Coronal Spectrometer, a fiber optic based spectrograph, was designed for global and simultaneous measurements of the thermal electron temperature and the solar wind velocity in the solar corona. The first ever experiment of this nature was conducted in conjunction with the total solar eclipse of 11 August 1999 in Elazig, Turkey. Here twenty fiber optic tips were positioned in the focal plane of the telescope to observe simultaneously at many different latitudes and two different radial distances in the solar corona. The other ends were vertically stacked and placed at the primary focus of the spectrograph. By isolating the K-coronal spectrum from each fiber the temperature and the wind sensitive intensity ratios were calculated.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Validation and Assessment of DMSP Electron Temperatures in the Topside Ionosphere
Geomagnetic disturbances in the near earth space environment can adversely affect numerous military and Department of Defense (DoD) systems and operations. To improve the prediction accuracy of such disturbances, the Global Assimilation of Ionospheric Measurements (GAIM) working group is spearheading an effort to incorporate near real-time ionospheric measurements into the next generation of space environment forecast models. Since the model software is designed to automate the data ingest process, the need arises to examine and validate the quality of such measurements before being assimilated into such a model. One such measurement to explore, which is the focus of this research, is the Defense Military Satellite Program (DMSP) measured electron temperature (Te). DMSP Te data were validated against near simultaneous incoherent scatter radar (ISR) Te measurements from Millstone Hill, MA and Sondrestrom, Greenland for a select 43 conjunctions between Winter 1996 and Summer 2000. DMSP Te measurements for a given overpass were averaged, while ISR Te values were either averaged or extrapolated, depending on the ISR mode, to determine Te comparison values. In some cases, instrument related anomalies produced unreliable measurements. Of the 37 Millstone and six Sondrestrom conjunctions compared, DMSP Te values exceeded ISR Te values by an average of about 25 percent, which is nearly three times the mean ISR uncertainty. Photoelectrons collected by the DMSP Electron Probe contaminated Te values particularly during solar minimum.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Planetary Asteroid Defense Study
The threat posed to Earth and Earth-orbiting spacecraft by natural space debris (asteroids, comets and meteor streams) is examined in an effort to quantify the threat and identify available, low cost mitigation measures. Our study found that the Earth resides in a swarm of natural debris that consists of at least three families of asteroids (the Apollo, Aten and Amor asteroids), several short-period comets and at least 11 active meteor streams.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Holes
Ionospheric scintillation of GPS signals threatens navigation and military operations by degrading performance or making GPS unavailable. Scintillation is particularly active, although not limited to, a belt encircling the earth within 20 of the geomagnetic equator. This belt also hosted roughly half of the completed U.S. military operations in the last decade. We examined scintillation data from Ascension Island, U.K. and Ancon, Peru, in the Atlantic and Americas longitudinal sector at as well as data from Parepare, Indonesia and Marak Parak, Malaysia in the Pacific longitudinal sector. From these data, we calculate percent probability of occurrence of scintillation at various intensities described by the S4 index. Additionally, we determine Dilution of Precision at one minute resolution. Diurnal, seasonal and solar cycle characteristics are examined. Latitudinal and longitudinal comparisons are made. Our findings are consistent with previous research. Unlike previous research, however, we attempt to replace, or impute, missing S4 values in order to better capture the extent of scintillation. In doing so, we study data gaps, or holes, and characterize them.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Space Doctrine for the 21st Century
Reliable thunderstorm forecasts are essential to safety and resource protection at Cape Canaveral. Current methods of forecasting day-2 thunderstorms provide little improvement over forecasting by persistence alone and are therefore in need of replacement. This thesis focuses on using the mesoscale eta model to develop an index for improved forecasting of day-2 thunderstorms. Surface observations from the shuttle landing facility and the coincident output of the mesoscale eta forecast model were collected for the period of 1 May to 14 Sep 1998. Variables extracted from the eta forecast model output, as well as derived variables that incorporate the eta output variables, were divided into three data sets. A univariate logistic regression with the occurrence of a thunderstorm in the surface observation (the "truth") as the dependent variable, and the output/derived values from the eta model as the independent variable, discarded all but 94 of over 250 predictors that were considered important to thunderstorm occurrence. The data sets were further divided into model-building and validation sets for the purpose of building a logistic regression model. Regression coefficients were developed using the model-building sets and then applied to the validation sets for the purpose of forecasting a thunderstorm.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Societal Impact of Spaceflight, End Matter
Societal Impact of Spaceflight: The purpose of this volume is to examine the effects of spaceflight on society through scholarly research, making use especially of the tools of the historian and the broader social sciences and humanities. Has the Space Age indeed had a significant effect on society? If so, what are those influences? What do we mean by an "impact" on society? And what parts of society? Conversely, has society had any effect on spaceflight? What would be different had there been no Space Age?This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Customization of Discriminant Function Analysis for Prediction of Solar Flares
This research is an extension to the research conducted by K. Leka and G. Barnes of the Colorado Research Associates Division, Northwest Research Associates, Inc. in Boulder, Colorado (CORA) in which they established no single photospheric solar parameter could sufficiently identify a flare-producing active region (AR). Their research then explored the possibility a linear combination of parameters used in a multivariable discriminant function (DF) could adequately predict solar activity. The purpose of this research is to extend the DF research conducted by Leka and Barnes by refining the method of statistical discriminant analysis (DA) with the goal of selecting those photospheric magnetic parameters most capable of identifying flare-producing active regions in hopes of increasing the reliability of short term flare warnings and the understanding of flare production. The data for this research were photospheric vector magnetograms captured by the Imaging Vector Magnetograph (IVM) at the University of Hawai`i Mees Solar Observatory at Haleakala and provided by CORA.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Shaping the Space Medium
In 1999, USCINCSPACE/J5 commissioned a study through the Institute for National Security Studies asking the question, "How should the USCINCSPACE go about shaping the region of space in accordance with the National Military Strategy?" The research question went on to ask if there are any systematic approaches used by other CINCs to shape their AOR that can be used by USCINCSPACE to shape the region of space. This study analyzes one way in which the USCINSSPACE might best shape the medium of space. The 1997 National Military Strategy builds on the premise that the United States will remain globally engaged to shape the international environment and create conditions favorable to US interests and global security. Does this include shaping the region of space? Terms like shaping, region, AOR, and aerospace have different contextual meanings and often raise emotional responses. This paper places those terms in their proper context. Finally, this paper directly applies the geographic CINC model for shaping as it is described in the US National Military Strategy to the space medium and determines its applicability for the USCINCSPACE. This paper recommends that the USCINCSPACE adopt the use of the guidelines given by the geographic CINC model, as they are described in the US National Military Strategy, to shape the space medium.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Improved Modeling of Midlatitude D-Region Ionospheric Absorption of High Frequency Radio Signals During Solar X-Ray Flares
The purpose of this research was to improve modeling of midlatitude D-region ionospheric absorption of high frequency radio signals during solar X-ray flares through analysis of HF propagation data obtained during the HF Investigation of D-region Ionospheric Variation Experiment (HIDIVE) and obtained at the Canadian Space Agency NORSTAR riometer in Pinawa, Manitoba, Canada and X-ray flux data, as reported by GOES satellites. The findings of the data analysis were then used to validate and suggest improvements for two existing HF absorption models, the operational Space Weather Prediction Center (SWPC) D-region Absorption model and the physical AbbyNormal model. Analysis of the HIDIVE data revealed an absorption dependence on signal frequency and a dependence on solar zenith angle which differ from those used in the SWPC model. Analysis of nitric oxide (NO) density data obtained with the Student Nitric Oxide Explorer and during the Halogen Occultation Experiment provided improved methods of defining NO profiles within AbbyNormal.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Houston, You Have a Problem
Over the next three years the National Aeronautics and Space Administration (NASA) is undergoing a critical transition by retiring the Space Shuttle program while completing construction of the International Space Station (ISS) by 2010. During this timeframe, NASA is undertaking its most complex and costly acquisition program, termed Constellation, to provide a Space Shuttle replacement capability by 2011 followed by subsequent lunar missions by 2018 in preparation for Mars missions. This paper demonstrates why NASA should restructure its proposed manned spaceflight program to ensure the success of NASA's future manned spaceflight program following the retirement of the Space Shuttle program in 2010. The arguments outlined in this paper for proposed restructure of NASA's future manned spaceflight program center on several key elements: national interest, prohibitive cost, manned spaceflight risk and contributions to science and exploration. The recommendations focus on ensuring long-term viability and success of future US manned space programs.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Best Defense
The us is at a crossroads with respect to space. The challenge that now presents itself is how to craft a strategy that maintains the united states' asymmetric advantage in space while moving from the current age of uncontested access to one where access must be assured by deliberate actions. All military strategies are key to the overall grand strategy of the state, but the us military strategy for space holds a special degree of influence upon the overall success of us grand strategy. This special degree of influence derives from the characteristic offensive omnipresence of orbital platforms; just as the advent of intercontinental missile delivery systems established the offensive omnipresent threat of nuclear weapons. As such, strategists must take special care to weigh not only the necessities of the military strategy for space, but also the broader impact on the nation's grand strategy. What type of strategy would best achieve us security objectives? Should the us adopt a largely defensive strategy to protect its interests and preserve its advantages or does the adage "the best defense is a strong offense" hold true for space?This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
