Walking at the Speed of Light is a perceptive offering of memoir and reflections that can be taken one at a time and provide insight and healing for all kinds of darkness. Although many books have addressed grief and depression related to Christian faith, a book that gives readers a Christian perspective on these subjects through forward thinking including organ donation and positive life building offers a unique opportunity. Walking at the Speed of Light begins with the death of Cheryl J. Heser’s thirty-three-year-old son, Joshua, the grief experiences that followed, and the organ donation that affected the lives of over 100 people. Cheryl then provides chapters related to the Light of the World, sharing insight and nurturing for grief and depression as well as an enthusiastic embracing of all aspects of the enlightened Christian faith journey.

War at the Speed of Light describes the revolutionary and ever-increasing role of directed-energy weapons (such as laser, microwave, electromagnetic pulse, and cyberspace weapons) in warfare. Louis A. Del Monte delineates the threat that such weapons pose to disrupting the doctrine of Mutually Assured Destruction, which has kept the major powers of the world from engaging in nuclear warfare. Potential U.S. adversaries, such as China and Russia, are developing hypersonic missiles and using swarming tactics as a means to defeat the U.S. military. In response, the U.S. Department of Defense established the 2018 National Security Strategy, emphasizing directed-energy weapons, which project devastation at the speed of light and are capable of destroying hypersonic missiles and enemy drones and missile swarms. Del Monte analyzes how modern warfare is changing in three fundamental ways: the pace of war is quickening, the rate at which weapons project devastation is reaching the speed of light, and cyberspace is now officially a battlefield. In this acceleration of combat called “hyperwar,” Del Monte shows how disturbingly close the world is to losing any deterrence to nuclear warfare.

Spacecraft depend on electronic components that must perform reliably over missions measured in years and decades. Space radiation is a primary source of degradation, reliability issues, and potentially failure for these electronic components. Although simulation and modeling are valuable for understanding the radiation risk to microelectronics, there is no substitute for testing, and an increased use of commercial-off-the- shelf parts in spacecraft may actually increase requirements for testing, as opposed to simulation and modeling. Testing at the Speed of Light evaluates the nation's current capabilities and future needs for testing the effects of space radiation on microelectronics to ensure mission success and makes recommendations on how to provide effective stewardship of the necessary radiation test infrastructure for the foreseeable future.

A study of the new scientific understanding of consciousness and the mind as a fifth dimension of reality • Introduces the existence of a fifth dimension--one of mind--an inner- or hyperspace where time is transcended • Shows how the barrier of the speed of light is actually a gateway demarking the fifth dimension Since the introduction of Descartes’ dualism in the seventeenth century, the mind and the physical world have been viewed as disconnected entities. Yet qualities of mind such as awareness, purposeful action, organization, design, and even decision-making are present within the structure of matter and within the dimensions of space and time. The space-time continuum of scientists generally ignores the realm of the mind, though phenomena such as imaginary numbers, used by Einstein to combine space with time, are concepts that only exist in the mind. Marc Seifer contends that the inadequacy of four-dimensional models to account for our experience of mental phenomena points to the consciousness of the mind as a higher organizing principle, a fifth dimension where thoughts are as real and quantifiable as our familiar physical world. He shows that because thought enables us to move backward and forward through time--reflecting on the past and making plans for the future--this fifth dimension of mind breaks the laws of relativity, thereby transcending the speed of light. His extensive study of this fifth dimension ranges from relativity and ether theory to precognition, telepathy, and synchronicity, all from the perspective of the conscious universe.

A remarkable look at how the growth, technology, and politics of high-frequency trading have altered global financial markets In today’s financial markets, trading floors on which brokers buy and sell shares face-to-face have increasingly been replaced by lightning-fast electronic systems that use algorithms to execute astounding volumes of transactions. Trading at the Speed of Light tells the story of this epic transformation. Donald MacKenzie shows how in the 1990s, in what were then the disreputable margins of the US financial system, a new approach to trading—automated high-frequency trading or HFT—began and then spread throughout the world. HFT has brought new efficiency to global trading, but has also created an unrelenting race for speed, leading to a systematic, subterranean battle among HFT algorithms. In HFT, time is measured in nanoseconds (billionths of a second), and in a nanosecond the fastest possible signal—light in a vacuum—can travel only thirty centimeters, or roughly a foot. That makes HFT exquisitely sensitive to the length and transmission capacity of the cables connecting computer servers to the exchanges’ systems and to the location of the microwave towers that carry signals between computer datacenters. Drawing from more than 300 interviews with high-frequency traders, the people who supply them with technological and communication capabilities, exchange staff, regulators, and many others, MacKenzie reveals the extraordinary efforts expended to speed up every aspect of trading. He looks at how in some markets big banks have fought off the challenge from HFT firms, and how exchanges sometimes engineer technical systems to favor certain types of algorithms over others. Focusing on the material, political, and economic characteristics of high-frequency trading, Trading at the Speed of Light offers a unique glimpse into its influence on global finance and where it could lead us in the future.

Light -- our experience of light, our measurement of light, and the notion that light speed is constant -- can be understood to mark our interface with the cosmos. David A. Grandy's book moves from the scientific to the existential, from Einstein to Merleau-Ponty, from light as a phenomenon to light as that which is constitutive of reality. To measure the speed of light is to measure something about the way we are measured or blended into the cosmos, and that universal blending predetermines our measurement of light speed in favor of a universal or constant value. It's quite a trip, one aimed at scientists who have pondered light speed constancy, philosophers inclined to question the idea that mind and world are distinct, and scientifically or philosophically inclined persons who enjoy stretching themselves in new ways.

Light is the most important part of our lives. Louise Riofrio, while working as a Scientist at NASA, made the biggest discovery of the century--the Speed of Light is changing. Starting when a child's eyes first open she describes how we learn about the world through light in our first few months of life, then how we discovered that Earth is round, and how we found we are part of a solar system and a galaxy. The Speed of Light takes you around the world from the Mediterranean to Hawaii in 100 illustrations showing where discoveries were made. This new edition shows how the size of the Universe is related to the cells of our bodies, a new discovery even closer to human life. The Speed of Light is your guide to the Universe.

Larry Mason Johnson Larry Mason Johnson I thought it was possible to paint a picture of what it might be like living (inside) strawberry fields forever. So I tried my very best, considering the circumstances. I also included a touch of “The Twilight Zone.” It’s for you to decide: did this really happen? Or is it a good story? 460 460

Though we take light for granted, the world's greatest scientists have long puzzled over its nature, properties, and behavior. Its incredible speed, mysterious frequency, relationship to color, form of travel, and uncanny ability to reflect, refract, diffract, and be absorbed altogether make light the ever-elusive quarry of science's greatest hunters of knowledge and understanding. This is the enthralling account of their investigations and discoveries, their conclusive insights and ongoing questions, enhanced by full-color photographs and explanatory visual aids. If you thought you knew everything there is to know about light, think again and read on.
