Have you ever wondered what is the most distant source of light we can see, or how a star shines? Did you know that black holes can blaze like cosmic beacons across intergalactic space, and that ancient radio waves might herald the ignition of the very first stars? Have you ever thought about what light really is? Five Photons explains what we know about the universe through five different journeys of light across space and time. They are tales of quantum physics and general relativity, stars and black holes, dark matter and dark energy. Let yourself be swept away on a journey of discovery towards a deeper understanding of the cosmos.

Vortex Atom, The: A New Paradigm by Barry R Clarke Pdf
With clear illustrations throughout and without recourse to quantum mechanics, the reader is invited to revisit unsolved problems lying at the foundations of theoretical physics. Maxwell and his contemporaries abandoned their search for a geometrical representation of the electric and magnetic fields. The wave-particle dilemma and Bose-Einstein statistical counting have resulted in unsatisfactory non-realistic interpretations. Furthermore, a simple structure of the hydrogen atom that includes hyperfine levels is still wanting.Working with the latest experimental data in photonics a proposed solution to the wave-particle dilemma is suggested based on an array of circular-polarized rays. The Bose-Einstein counting procedure is recast in terms of distinguishable elements. Finally, a vortex model of a 'particle' is developed based on a trapped photon. This consists of a single ray revolving around a toroidal surface, and allows a geometrical definition of mass, electric potential, and magnetic momentum. With the adjustment of two parameters, values to 4 dp for the hyperfine frequencies (MHz) of hydrogen can be obtained for which a computer program is available.
Flight Measurements of the Flying Qualities of Five Light Airplanes by Paul A. Hunter Pdf
Results are presented of an investigation of stability, controllability, and stalling characteristics of five light airplanes. The effect of slots on the flying qualities of one of the airplanes is also shown. These five airplanes are considerd typical of the light airplanes now being manufactured.
James Elkins's How to Use Your Eyes invites us to look at--and maybe to see for the first time--the world around us, with breathtaking results. Here are the common artifacts of life, often misunderstood and largely ignored, brought into striking focus. With the discerning eye of a painter and the zeal of a detective, Elkins explores complicated things like mandalas, the periodic table, or a hieroglyph, remaking the world into a treasure box of observations--eccentric, ordinary, marvelous.
Physics, Metaphysics, and God - Third Edition by Jack W. Geis Pdf
"At long last, a promising dialogue between science and medicine has begun. A focal point of this discussion is healing and how it happens. Jack W. Geis shows how modern physics and spirituality are centrally involved in this debate. No one who is interested in the current interface between science, spirituality and medicine can afford to neglect his ideas."—Larry Dossey, MD, Author: Healing Beyond the Body, and Healing Words: The Power of Prayer and the Practice of Medicine "This book introduces some of the most perplexing and exciting aspects of the revolution going on in physics today as it continues toward an increasingly metaphysical basis for defining reality. This exciting scientific revolution should be shared by everyone and the issues taken up in this book form a basis for that participation. That the math is not in the chalk is becoming increasingly evident, as well as the question as to which is more substantial."—Dr. Laurance R. Doyle, Astrophysics and Planetary Science, Center for the Study of Life in the Universe, SETI Institute

Mathematics for Neuroscientists by Fabrizio Gabbiani,Steven James Cox Pdf
Virtually all scientific problems in neuroscience require mathematical analysis, and all neuroscientists are increasingly required to have a significant understanding of mathematical methods. There is currently no comprehensive, integrated introductory book on the use of mathematics in neuroscience; existing books either concentrate solely on theoretical modeling or discuss mathematical concepts for the treatment of very specific problems. This book fills this need by systematically introducing mathematical and computational tools in precisely the contexts that first established their importance for neuroscience. All mathematical concepts will be introduced from the simple to complex using the most widely used computing environment, Matlab. This book will provide a grounded introduction to the fundamental concepts of mathematics, neuroscience and their combined use, thus providing the reader with a springboard to cutting-edge research topics and fostering a tighter integration of mathematics and neuroscience for future generations of students. A very didactic and systematic introduction to mathematical concepts of importance for the analysis of data and the formulation of concepts based on experimental data in neuroscience Provides introductions to linear algebra, ordinary and partial differential equations, Fourier transforms, probabilities and stochastic processes Introduces numerical methods used to implement algorithms related to each mathematical concept Illustrates numerical methods by applying them to specific topics in neuroscience, including Hodgkin-Huxley equations, probabilities to describe stochastic release, stochastic processes to describe noise in neurons, Fourier transforms to describe the receptive fields of visual neurons Allows the mathematical novice to analyze their results in more sophisticated ways, and consider them in a broader theoretical framework
Biophotonics: Spectroscopy, Imaging, Sensing, and Manipulation by Baldassare Di Bartolo,John Collins Pdf
This volume describes an impressive array of the current photonic-related technologies being used in the investigation of biological systems. The topics include various types of microscopy (fluorescence correlation microscopy, two-photon microscopy), sensitive detection of biological molecules, nano-surgery techniques, fluorescence resonance energy transfer, nano-plasmonics, terahertz spectroscopy, and photosynthetic energy conversion. The emphasis is on the physical principles behind each technique, and on examining the advantages and limitations of each.The book begins with an overview by Paras Prasad, a leader in the field of biophotonics, of several important optical techniques currently used for studying biological systems. In the subsequent chapters these techniques are discussed in depth, providing the reader with a detailed understanding of the basic physical principles at work. An excellent treatment of terahertz spectroscopy demonstrates how photonics is being extended beyond the visible region. Recent results in the use of femtosecond lasers as a tool to porate cell walls demonstrate that the manipulation of light can be used as a tool for the study and the treatment of biological systems. The field of Bio-photonics is broad and still growing, so cannot be covered comprehensively in one volume. But here the reader will find an introduction to some of the major tools used for studying biological systems, and at the same time a detailed, first-principles treatment of the physics behind these tools.
