Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an "idealist" inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion.
This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.
The book begins at the simplest level, develops the basics, and reinforces fundamentals, ensuring a solid foundation in the principles and methods of physics. It provides an ideal introduction for college-level students of physics, chemistry, and engineering; for motivated AP Physics students; and for general readers interested in advances in the sciences.
Nikola Tesla—a poet of invention—left behind a vast and intriguing legacy. He was a scientist, physicist, mathematician, electrical engineer, and extensively published author who spent his last decades scraping for funding for celestial projects and living out his final days in penurious solitude with a pigeon.

Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World’s Fair, Niagara Falls, and, finally, the death chamber—Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair.
Empires of Light is the gripping history of electricity, the “mysterious fluid,” and how the fateful collision of Edison, Tesla, and Westinghouse left the world utterly transformed.

This book will be mandatory reading for anyone working on the foundations of modern devices such as free electron lasers, plasma accelerators, synchroton sources and other modern sources of bright, coherent radiation with high spectral density.
Impartially written by expert authors in the field from a renowned applied science institution, who are in the unique position of having both experience in public and private research and in teaching, this comprehensive book can be used for teaching beginners in the field as well as providing further education to specialized staff, students and researchers.
In this simple, descriptive treatment of Tesla's work:
- We start with the analysis of Tesla's experiment in his US patent 787412, providing explanations for his lower bounds, requirements, and superluminal speeds. Modes of operation of Tesla transformer are analyzed, and the true nature of the so-called Tesla-wave explained, considering what renders it to be the most significant technological discovery to date.
- We recognize that the very discovery of radio is a witness to the physical existence of invisible, exclusively 3-dimensional worlds, and spherical potential waves in a fully three-dimensional imaginary space are a fundamental phenomenon and physical reality.
- We progress to discuss implications and applications, and claim that properly constructed radio waves do not travel through our visible domain, allowing for efficient wireless energy transfer irrespective of distance.
- Finally, concentrated in one of the last of the 12 chapters, we present a concise mathematical treatment based on Maxwell's equations in characterizing the Tesla effect.
Redefining the thinking outside-the-box and challenging the state of the art in modern physics, I submit this innovation to your careful scrutiny. This descriptive work is accessible to any reader, including physics and mathematics scholars skilled in the art. The combined experience in the above treatment yields a novel, simple, yet comprehensive view of the spatial construction of the universe, above and beyond the everyday three-dimensional reality experienced by physical senses.
No sensationalist descriptions involving time travel, weapons of global destruction, Soviet military research, mind alteration, age reversal, UFOs, aliens, and a myriad of other manufactured and unrelated topics, are contained in this text. No strings, tensors, elementary particles, or any of the traditional special relativity effects are associated with Tesla waves, and are not mentioned in this text. The most significant problem in theoretical interpretation of Tesla's ideas to date - was the avoidance of the most obvious solution.
Read this flagship book, and discover that the universe is so small that we are all intimately connected through a countably infinite set of pathways of ever decreasing length, and that it is yet so large, that it escapes our senses.
Universe is a lattice of countably infinitely many, mutually embedded, distinct, experientially equivalent, fully-fledged three-dimensional worlds, with all corresponding lengths ratio of Pi/2. Illustrated in C^3 , universe is simply a sphere of radius zero.
Maxwell made numerous other contributions to the advancement of science, but the greatest work of his life was devoted to electricity. An Elementary Treatise on Electricity appeared at a time when very few books on electrical measurements were available to students, and its compact treatment not only elucidates the theory of electricity but also serves to develop electrical ideas in readers' minds. The author describes experiments that demonstrate the principal facts relating an electric charge as a quantity capable of being measured, deductions from these facts, and the exhibition of electrical phenomena.
This volume, published posthumously from Maxwell's lecture notes at the Cavendish Laboratory — which he founded at the University of Cambridge — is supplemented by a selection of articles from his landmark book, Electricity and Magnetism. A classic of science, this volume is an eminently suitable text for upper-level undergraduates and graduate students.

“Semiconductor Laser Engineering, Reliability andDiagnostics: A Practical Approach to High Power and Single ModeDevices”. By Peter W. Epperlein
Prof. em. Dr. Heinz Jäckel, High Speed Electronics andPhotonics, Swiss Federal Institute of Technology ETHZürich, Switzerland
The book “Semiconductor Laser Engineering, Reliabilityand Diagnostics” by Dr. P.W. Epperlein is a landmark in therecent literature on semiconductor lasers because it fills alongstanding gap between many excellent books on laser theory andthe complex and challenging endeavor to fabricate these devicesreproducibly and reliably in an industrial, real worldenvironment.
Having worked myself in the early research and development ofhigh power semiconductor lasers, I appreciate the competent,complete and skillful presentation of these three highlyinterrelated topics, where small effects have dramatic consequenceson the success of a final product, on the ultimate performance andon the stringent reliability requirements, which are the name ofthe game.
As the title suggests the author addresses three tightlyinterwoven and critical topics of state-of-the-art power laserresearch. The three parts are: device and mode stabilityengineering (chapter 1, 2), reliability mechanisms and reliabilityassessment strategies (chapter 3, 4, 5, 6) and finally material anddevice diagnostics (chapter 7, 8, 9) all treated with a strongfocus on the implementation. This emphasis on the complex practicalaspects for a large-scale power laser fabrication is a truehighlight of the book.
The subtle interplay between laser design, reliabilitystrategies, advanced failure analysis and characterizationtechniques are elaborated in a very rigorous and scientific wayusing a very clear and easy to read representation of the complexinterrelation of the three major topics. I will abstain from tryingto provide a complete account of all the topics but mainlyconcentrate on the numerous highlights.
The first part 1 “Laser Engineering” is dividedin two chapters on basic electronic-optical, structural, materialand resonator laser engineering on the one side, and on single modecontrol and stability at very high, still reliable power-levelswith the trade-off between mirror damage, single mode stability onthe other side. To round up the picture less well-known conceptsand the state-of-the-art of large-area lasers, which can be forcedinto single-mode operation, are reviewed carefully. The subtle andcomplex interplay, which is challenging to optimize for a designfor reliability and low stress as a major boundary condition iscrucial for the design. The section gives a rather complete andwell-referenced account of all relevant aspects, relations andtrade-offs for understanding the rest of the book.
The completeness of the presentation on power laser diodedesign based on basic physical and plausible arguments is mainlybased on analytic mathematical relations as well as experimentsproviding a new and well-balanced addition for the power diodelaser literature in particular. Modern 2D self-consistentelectro-optical laser modeling including carrier hole burning andthermal effects – this is important because the weak opticalguiding and gain-discrimination depend critically on rather smallquantities and effects, which are difficult to optimizeexperimentally – is used in the book for simulation results,but is not treated separately.
The novel and really original, “gap-filling” bulkof the book is elaborated by the author in a very clear way in thefollowing four chapters in the part 2 “LaserReliability” on laser degradation physics and mirror designand passivation at high power, followed then by two veryapplication oriented chapters on reliability design engineering andpractical reliability strategies and implementation procedures.This original combination of integral design and reliabilityaspects – which are mostly neglected in standardliterature – is certainly a major plus of this book. I likedthis second section as a whole, because it provides excellentinsights in degradation physics on a high level and combines it inan interesting and skillful way with the less“glamorous” (unfortunately) but highly relevantreliability science and testing strategies, which is particularlyimportant for devices operating at extreme optical stresses withchallenging lifetime requirements in a real wordenvironment.
Finally, the last part 3 “Laser Diagnostics”comprising three chapters, is devoted mainly to advancedexperimental diagnostics techniques for material integrity,mechanical stress, deep level defects, various dynamic laserdegradation effects, surface- and interface quality, and mostimportantly heating and disordering of mirrors and mirror coatings.The topics of characterization techniques comprising micro-Raman-and micro-thermoreflectance-probing, 2K photoluminescencespectroscopy, micro-electroluminescence and photoluminescencescanning, and deep-level-transient spectroscopy have been pioneeredby the author for the specific applications over many yearsguaranteeing many competent and well represented insights. Thesetechniques are brilliantly discussed and the informationdistributed in many articles by the author has been successfullyunified in a book form.
In my personal judgment and liking, I consider the parts 2and 3 on reliability and diagnostics as the most valuable and truenovel contribution of the book, which in combination with theextremely well-covered laser design of part 1 clearly fill the gapin the current diode laser literature, which in this detail hascertainly been neglected in the past.
In summary, I can highly recommend this excellent,well-organized and clearly written book to readers who are alreadyfamiliar with basic diode laser theory and who are active in theacademic and industrial fabrication and characterization ofsemiconductor lasers. Due to its completeness, it also serves as anexcellent reference of the current state-of-the-art in reliabilityengineering and device and material diagnostics.
Needless to mention that the quality of the book, itsrepresentations and methodical structure meet the highestexpectation and are certainly a tribute from the long and broadexperience of the author in academic laser science and theindustrial commercialization of high power diode lasers.
In my opinion, this book was a pleasure to read and due toits quality and relevance deserves a large audience in the powerdiode laser community!

“Semiconductor Laser Engineering, Reliability andDiagnostics: A Practical Approach to High Power and Single ModeDevices”. By Peter W. Epperlein
Dr. Chung-en Zah, Research Director,Semiconductor Technologies Research, S&T Division,Corning Incorporate, Corning NY, USA
This book covers for the first time the three closelyinterrelated key laser areas of engineering (design), reliabilityand diagnostics in one book, written by the well-known practitionerin cutting-edge optoelectronics industries, Dr. Peter W. Epperlein.The book closes the gap in the current book literature and is thusa unique and excellent example of how to merge design, reliabilityand diagnostics aspects in a very professional, profound andcomplete manner. All physical and technological principles,concepts and practical aspects required for developing andfabricating highly-reliable high-power single-mode laser productsare precisely specified and skilfully formulated along with all thenecessary equations, figures, tables and worked-out examples makingit easy to follow through the nine chapters. Hence, this uniquebook is a milestone in the diode laser literature and is anexcellent reference book not only for diode laser researchers andengineers, but also diode laser users.
The engineering part starts with a very informative andclear, well-presented account of all necessary basic diode lasertypes, principles, parameters and characteristics for an easy andquick understanding of laser functionality within the context ofthe book. Along with an elaborate and broad discussion of relevantlaser material systems, applications, typical output powers,power-limiting factors and reliability tradeoffs, basic fabricationand packaging technologies, this excellent introductory section iswell suited to become quickly and easily familiar with practicalaspects and issues of diode laser technologies. Of specialimportance and high usefulness is the first analytic andquantitative discussion in a book on issues of coupling laser powerinto optical single mode fibers. The second section discusses in awell-balanced, competent and skilful way waveguide topics such asbasic high-power design approaches, transverse vertical and lateralwaveguide concepts, stability of the fundamental transverse lateralmode and fundamental mode waveguide optimization techniques byconsidering detrimental effects such as heating, carrier injection,spatial hole burning, lateral current spreading and gain profilevariations. Less well-known approaches to force large-area lasersinto a single mode operation are well-identified and carefullydiscussed in depth and breadth. All these topics are elaborated ina very complete, rigorous and scientific way and are clearlyarticulated and easy to read. In particular, the book works out thecomplex interaction between the many different effects to optimizehigh-power single-mode performance at ultimate reliability and thusis of great benefit to every researcher and engineer engaged inthis diode laser field.
Another novelty and highlight is, for the first time ever inbook form, a comprehensive yet concise discussion of diode laserreliability related issues. These are elaborated in four distinctchapters comprising laser degradation physics and modes, opticalstrength enhancement approaches including mirrorpassivation/coating and non-absorbing mirror technologies, followedby two highly relevant product-oriented chapters on reliabilitydesign engineering concepts and techniques and an elaboratereliability test plan for laser chip and module productqualification. This original and novel approach to link laserdesign to reliability aspects and requirements provides both, mostuseful insight into degradation processes such as catastrophicoptical mirror damage on a microscopic scale, and a wide selectionof effective remedial actions. These accounts, which are of highestsignificance for lasers operating at the optical stress limit dueto extremely high output power densities and most demandinglifetime requirements are very professionally prepared anddiscussed in an interesting, coherent and skilfulmanner.
The diagnostics part, consisting of three very elaboratechapters, is most unique and novel with respect to other diodelaser books. It discusses for the first time ever on a very highlevel and in a competent way studies on material integrity,impurity trapping effects, mirror and cavity temperatures, surface-and interface quality, mirror facet disorder effects, mechanicalstress and facet coating instability, and diverse laser temperatureeffects, dynamic laser degradation effects and mirror temperaturemaps. Of highest significance to design, performance andreliability are the various correlations established between laserdevice and material parameters. The most different andsophisticated experiments, carried out by the author at micrometerspatial resolutions and at temperatures as low as 2K, providehighly valuable insights into laser and material qualityparameters, and reveal for the first time the origins of high powerlimitations on an atomic scale due to local heating effects anddeep level defects. It is of great benefit, that the experimentaltechniques such as Raman spectroscopy, various luminescencetechniques, thermoreflectance and deep-level transientspectroscopy, pioneered by the author for the specific experimentson lasers, are discussed with great expertise in depth and breadth,and the numerous paper articles published by the author are nowrepresented in this book.
The book has an elaborate table of contents and index, whichare very useful, over 200 illustrative figures and tables, andextensive lists of references to all technical topics at the end ofeach of the nine chapters, which make it easy to follow from coverto cover or by jumping in at random areas of special interest.Moreover, experimental and theoretical concepts are alwaysillustrated by practical examples and data.
I can highly recommend this extremely relevant,well-structured and well-formulated book to all practisingresearchers in industrial and academic diode laser R&Denvironments and to post-graduate engineering students interestedin the actual problems of designing, manufacturing, testing,characterising and qualifying diode lasers. Due to its completenessand novel approach to combine design, reliability and diagnosticsin the same book, it can serve as an ideal reference book as well,and it deserves to be welcomed wordwide by the addressedaudience.

This book represents a well thought description of threefundamental aspects of laser technology: the functioningprinciples, the reliability and the diagnostics. From this point ofview, and, as far as I know, this is a unique example of a bookwhere all these aspects are merged together resulting in awell-balanced presentation. This helps the reader to move with easebetween different concepts since they are presented in a coherentmanner and with the same terminology, symbols anddefinitions.
The book reads well. Despite the subtitle indicates that itis a practical approach, the book is also correct from a formalpoint of view and presents the necessary equations and derivationsto understand both the physical mechanisms and the practicalitiesvia a set of useful formulas. In addition, there is the moreimportant aspect of many real-life examples of how a laser isactually manufactured and which the relevant parameters thatdetermine its behaviour are. It impresses the amounts ofinformation that are given in the book: this would be more typicalof a thick handbook on semiconductor laser than of an agile book.Dr. Epperlein was able to identify the most important concepts andto present them in a clear though concise way.
I am teaching a course on Optoelectronics and I'm going toadvise students to refer to this book, because it has all thenecessary concepts and derivations for a systematic understandingof semiconductor lasers with many worked-out examples, which willhelp the student to grasp the actual problems of designing,manufacturing, testing and using semiconductor lasers. All thevarious concepts are joined to very useful figures, which, ifprovided to instructors as files, can be a useful add-on for theuse of the book as text for teaching. Concepts are always detailedwith numbers to give a feeling of their practical use.
In conclusion, I do find the book suitable for my teachingduties and will refer it to my students.

“Semiconductor Laser Engineering, Reliability andDiagnostics: A Practical Approach to High Power and Single ModeDevices”. By Peter W. Epperlein
Robert W. Herrick, Ph.D., Senior Component ReliabilityEngineer, Intel Corp., Santa Clara, California, USA
Dr. Epperlein has done the semiconductor laser community agreat service, by releasing the most complete book on the market onthe practical issues of how to make reliable semiconductorlasers.
While dozens of books have been written over the past coupleof decades on semiconductor laser design, only a handful have beenwritten on semiconductor laser reliability. Prior to the release ofthis book, perhaps 40% of the material could be obtained elsewhereby combining five books: one on laser design, one on laserreliability, one on reliability calculations, and a couple of laserreview books. Another 40% could be pieced together bycollecting 50 -100 papers on the subjects of laser design, laserfabrication, characterization, and reliability. The remaining 20%have not previously been covered in any comprehensive way. Only the introductory material in the first half of the firstchapter has good coverage elsewhere. The large majority of theknowledge in this book is generally held as “tradesecret” by those with the expertise in the field, and most ofthose in the know are not free to discuss. The author was fortunateenough to work for the first half of his career in the IBM researchlabs, with access to unparalleled resources, and the ability topublish his work without trade secret restrictions. The results arestill at the cutting edge of our understanding of semiconductorlaser reliability today, and go well beyond the empirical“black box” approach many use of “try everything,and see what works.” The author did a fine job of pullingtogether material from many disparate fields.
Dr. Epperlein has particular expertise in high power singlemode semiconductor lasers, and those working on those type oflasers will be especially interested in this book, as there hasnever been a book published on the fabrication and qualification ofsuch lasers before. But those in almost any field ofsemiconductor lasers will learn items of interest about devicedesign, fabrication, reliability, and characterization. Unlike most other books, which intend to convey the scientificfindings or past work of the author, this one is written more as a“how to” manual, which should make it more accessibleand useful to development engineers and researchers in the field.It also has over 200 figures, which make it easier to follow. As with many books of this type, it is not necessary to read itfrom cover-to-cover; it is best skimmed, with deep diving into anyareas of special interest to the reader. The book isremarkable also for how comprehensive it is – even expertswill discover something new and useful.
Dr. Epperlein’s book is an essential read for anyonelooking to develop semiconductor lasers for anything other thanpure research use, and I give it my highest recommendation.

A revelatory look at our national power grid--how it developed, its current flaws, and how it must be completely reimagined for our fast-approaching energy future.
America's electrical grid, an engineering triumph of the twentieth century, is turning out to be a poor fit for the present. It's not just that the grid has grown old and is now in dire need of basic repair. Today, as we invest great hope in new energy sources--solar, wind, and other alternatives--the grid is what stands most firmly in the way of a brighter energy future. If we hope to realize this future, we need to reimagine the grid according to twenty-first-century values. It's a project which forces visionaries to work with bureaucrats, legislators with storm-flattened communities, moneymen with hippies, and the left with the right. And though it might not yet be obvious, this revolution is already well under way.
Cultural anthropologist Gretchen Bakke unveils the many facets of America's energy infrastructure, its most dynamic moments and its most stable ones, and its essential role in personal and national life. The grid, she argues, is an essentially American artifact, one which developed with us: a product of bold expansion, the occasional foolhardy vision, some genius technologies, and constant improvisation. Most of all, her focus is on how Americans are changing the grid right now, sometimes with gumption and big dreams and sometimes with legislation or the brandishing of guns.
The Grid tells--entertainingly, perceptively--the story of what has been called "the largest machine in the world": its fascinating history, its problematic present, and its potential role in a brighter, cleaner future.
For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders—complete with roller coasters and radar, computer networks and psychopharmaceuticals.
In Electric Universe, the great discoverers come to life in all their brilliance and idiosyncrasy, including the visionary Michael Faraday, who struggled against the prejudices of the British class system, and Samuel Morse, a painter who, before inventing the telegraph, ran for mayor of New York City on a platform of persecuting Catholics. Here too is Alan Turing, whose dream of a marvelous thinking machine—what we know as the computer—was met with indifference, and who ended his life in despair after British authorities forced him to undergo experimental treatments to “cure” his homosexuality.
From the frigid waters of the Atlantic to the streets of Hamburg during a World War II firestorm to the interior of the human body, Electric Universe is a mesmerizing journey of discovery.

Recommended by many institutions. Electromagnetism. SecondEdition has also been adopted by the Open University as the coursebook for its third level course on electromagnetism.
Timeless and collectible, the lectures are essential reading, not just for students of physics but for anyone seeking an introduction to the field from the inimitable Feynman.
Starting with an introductory chapter on electrostatics, the treatment advances to the electrostatic field of free charges; dielectric theory; electrostatic energy, force, and capacitance; electric current; and direct-current circuits. Subsequent topics include steady-state magnetism, electromagnetic induction, magnetic properties of matter, transient currents, analysis of alternating-current circuits, Maxwell's equations, and electromagnetic waves.
Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet.
Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago.
Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all?
Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.
The book of Engineering Mechanics covers depth explanations on mechanics problems. It explains the rest and in motion mechanisms with the use of scalar method and the SI Units are explained throughout the book.
