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In today’s financial markets, trading floors on which brokers buy and sell shares face-to-face have increasingly been replaced by lightning-fast electronic systems that use algorithms to execute astounding volumes of transactions.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.

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.

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 comprehensive guide to the therapeutic benefits of light and color and how they affect our physical and psychological well-being • Shares scientific research on how different wavelengths of light influence our cells, brain function, sleep patterns, and emotional stability • Examines several forms of light therapy, including chromotherapy, heliotherapy, actinotherapy, and thermotherapy • Explains how to use light and color therapy, maximize the benefits of sunlight, and avoid the health risks of new light sources such as compact fluorescents and LEDs Beginning with sun worship in prehistory and sunshine therapies in ancient Egypt, Greece, and India, light has long been associated with the sublime, the divine, and healing. Yet only recently have we begun to understand how different parts of the light spectrum, from infrared to ultraviolet, can affect our physical and psychological well-being. Covering the historic, scientific, and spiritual aspects of light and its role in energy medicine, Anadi Martel explores the vibrational nature of light and the interaction between light, biology, and consciousness. He demonstrates light’s incredible effects on the physical, energetic, and cognitive dimensions of life and examines several forms of light therapy, including chromotherapy (color therapy), heliotherapy (sun therapy), actinotherapy (ultraviolet therapy), and thermotherapy (infrared therapy). He details how to use light therapy daily, get optimal benefits from sunlight, and avoid the health risks of new artificial lighting such as compact fluorescents and LEDs. Combining his own 30 years of research with practical insight from the many phototherapy pioneers he’s encountered, the author examines scientific studies on how specific wavelengths of light influence our cells and DNA, brain function, sleep patterns, and emotional stability; speed the healing of wounds; and are effective in the treatment of disease, including arthritis, stroke, Alzheimer’s, Parkinson’s, and brain and nerve injuries. Exploring the spiritual aspects of light, the author explains why auras and halos have been used to represent sages and saints of all traditions, revealing the intimate link between light and consciousness. Investigating the many laser, monochrome, audiovisual, and infrared machines designed to heal disease and treat emotional disorders, Martel also reveals promising medical applications for light that are currently in development, inviting the reader not only to appreciate the complexities of light but to maximize its therapeutic dimensions.

Cutnell and Johnson has been the #1 text in the algebra-based physics market for almost 20 years. The 10th edition brings on new co-authors: David Young and Shane Stadler (both out of LSU). The Cutnell offering now includes enhanced features and functionality. The authors have been extensively involved in the creation and adaptation of valuable resources for the text. This edition includes chapters 18-32.

Some theoreticians contemplate and formulate the physics of tachyons, which are hypothetical particles, that would always travel faster than light but which could never slow down to the speed of light just as they anticipate sublight speed massive particles never being able to achieve light speed. So my theoretical work on the physics and kinematics of light-speed massive systems sets me apart from general trends in the theoretical field of relativistic astronautics. This book is a continuation of how and why we may be able to, at some future time, travel at the speed of light.
