5 comments about Tesla: Man Out of Time.

1. Cheney provides a lot of in depth information about Tesla's personal life, which at times is interesting. She refers often to his personal letters, which is information that is often hard to find in other biographies. However, there are a lot of lackings in the book as well. First, for anyone with a scientific or engineering background it is unsatisfying. Cheney's reiteration of Tesla's language when referring to his inventions is often archaic and unclear. I'm not sure her educational background, but she does not seem to be able to convey the engineering significance of his ideas. Secondly, she seems to almost be "defending" Tesla throughout the book. It doesn't necessarily detract from the book, but it comes across as desperate. Finally, it seems like the book's a little long. I feel like some information could be left behind. Nevertheless, for a compelte biography of all aspects of Tesla's life, this is the one for you--just be ready to focus more on his social interactions than his inventions.



2. For some odd reason, there are not very many books out there on Tesla. This one is all it takes.
   
   The way he could visualize an invention with such focus that he could even make changes to it based on how he saw it operating in his mind, without ever fabricating an actual model, was pretty wild. Some of the concepts he was working on almost 100 years ago still cannot be duplicated. Too bad he couldn't channel some of that genius toward his finances.
   
   The book has a good mix of his technical inventions as well as the personal aspects of this fascinating inventor's life.



3. I found this book to be absolutely mind-boggling. It is incredible that one man could be a pioneer in so many separate fields of technology. Moreover, it is incredible that one man can be traced back to be the originator of practically all of our global power and information infrastrucure- yet he benefitted so little for it in terms of either credit or wealth.
   
   Nikola Tesla was the single genius behind the the entire modern polyphase and single phase system for generating, transmitting, and utilizing electrical current. He was no mere theorist- he actually designed the dynamos, motors (the FIRST AC motors- when all the "experts" said that it was impossible), transformers, and automatic controls. It all occured to him in a flash in the 1880's. This alone should have made him the greatest of modern inventors, yet it was only a tiny part of his genius. Tesla also invented wireless communication (Marconi used his patents and lied about it.) Now combine this with his seminal work in superconductivity (he had to invent the technology to produce liquid oxygen on an indistrial scale), cryogenics, flourescent lights, radio-control, robotics, logic circuits, x-rays, radar, aeronautics, bladeless turbines, etc. He didn't merely predict the developments in these fields- if you look he held the original U.S. patents backed by detailed drawings and models (this book does an excellent job in tracing those patents.) Much of it dated from the 19th century- before the "electron" had been discovered or named.
   
   Yet, he received so little in credit or financial reward. After his time working for Edison (who cheated him him out of his promised fee for redesigning his DC dynamos), and after starting up and being forced out of his own arc lighting company, he was actually pennyless and forced to work as a street gang laborer during the recession of of 1886. He barely survived. In fact he often found it difficult to even pay his room rent during his life. One is stunned to find that this greatest of minds could be so poorly treated by society- it truly puts one own misfortunes into perspective...
   
   Those people who only associate the inventor with high frequency, high voltage stage spectaculars only see the tip of the iceburg. The only reason that Tesla even put on such theatrical displays was to try to attract investment capital from ignorant but wealthy men that did not understand his real work.
   
   Personally, Tesla was an enigma. He held that human beings were fundamentally no more than "meat machines." Yet there has seldom been a more altuistic personality. He did not subscibe to the rule of the jungle and the social Darwinism of his times. In fact, he essentially gave away his royalty rights to Westinghouse just to see that his superior system would actually be given to the world. Plus, there is the fact that Tesla experienced many instances of ESP and precognition in his life- yet he seemed to pss this off as a type of "mental radio" not yet explained. However, he never did come to grips as to how he could predict events in the future...
   
   One result of my reading the is book was that I grew ashamed that I kept a picture of Thomas Edison over my drawing board for years. Edison was a petty little man who behaved shamefully, especially concerning Tesla. Tesla was by far the greater innovator, plus a polished gentleman, linguist, and poet. One thing stuck out forcefully- Tesla was a great believer in developing solar, wind, geothermal, and ocean power as well as other forms of revewable energy. On the other hand, Edison held that such methods would not be needed for 50,000 years because just chopping down the South American jungles would provide us with that much fuel...
   
   "Nature and Nature's laws lay hid by night;
   God said, Let Tesla be, and all was light."



4. I'm fairly recently getting into Tesla. As I mentioned in another review I've always known who Tesla was, his work on Turbines and the Tesla Coil, but I didn't know too much about the man or his other inventions. When I saw the movie "The Prestige" I became far more intrigued into the person that was Tesla, so I decided to pick up a few things about the man. A great introductory, from what I can tell, is the PBS Documentary on DVD, but it has almost no depth and is really a very brief overview of the man and his inventions. "Tesla: A Man Out of Time" on the other hand seems to be a very in depth researched overview of the man, his inventions, and his friends.
   
   For the most part I thought this was a good book and it did keep my attention. It's not written in a manner of an engaging tale, but rather a critical analysis of the man's life. Some people may not enjoy this kind of writing as it has almost no story-form, but I'm the type of person who can sit down and read books on Mathematics or Ancient History, where it's a bit of a report like format. Granted "Tesla: A Man Out of Time" is not nearly as dry as some History texts I've come across over the years! One of the greatest misgivings for this book, however, is the way it is organized. The first half of the book seems to be organized by invention. So if we're dealing with Tesla's most monumental achievement for mankind, the Alternating Current, then that chapter takes us through all the years with the boons and plights of that invention. Actually a few chapters are dedicated to this. So we're dealing with a time period of like 1893 to the 1915's or so, if I remember the dates correctly. But Tesla invented a lot more in that time frame, such as the Tesla Coil. Granted I totally understand the approach to organizing it in this fashion, but Cheney doesn't really let you know the beginning dates when she starts talking about an invention so it's up to the reader to project when it is happening. This format could have worked if she was more forthcoming with some dates so people can put it in chronological order in their heads, though maybe she just didn't want to clutter the book with too many dates, which I would normally agree with, but not in this circumstance.
   
   Some other reviewers have commented on the her lack of explaining the technology in a lay readers understanding and some technical analysis shows that she likely didn't fully understand what Tesla's inventions did. That being said, I must point out that Cheney is not an engineer, she's a biographer and it says as much on the back of the book. While she does try to delve into the technical aspect, even I got confused with her explanation of Fusion and it's relation to Plasma, and I actually have a decent grasp on how Fission and Fusion work in terms of atomic structures. So people or engineers (specifically) reading this book may want to overlook that drastic aspect and focus more on the tale she's trying to tell about the man. I can kind of get over the technical aspect since there is very little explanation on the details and more focus on just Tesla's inventions and what he was general interested/motivated by as a result of his inventions. There are times when the author tries to liberally project her own conclusions to the reader such as Tesla's pre-concept of the circular "atom smasher" or cyclotron, which also lead to a premonition of Cathode Ray Tubes we've used in televisions and computer screens. While I think Tesla may have been on to something conceptually with the splitting of the atom, he by no means led the world to discover CRT technology as far as I can tell. However, I felt this kind of bias/commentary was in the minority overall.
   
   That being said I feel I have a better grasp of who Tesla was and what he has done for this world in the grand scheme of existence. This book is definitely more for those who want to know more about who he is, the hardships he dealt with, and what he invented over his life time. Cheney goes through great lengths to quote letters Tesla received from friends and his responses, even quoting news articles with his comments or comments from others. There is no doubt that she spent an exhaustive amount of time peering over news articles and letters from this great inventor. The book also has a grand amount of notations so you can do further reading when she abridges some of the quotes in this book. She goes over the types of people he has gone to over his lifetime and friends he's made like Anne Morgan (J.P. Morgan's daughter), Mark Twain, and having met Thomas Edison and worked for him. This is just a taste for who he met and worked with over his lifetime.
   
   In this book we meet a man who has practically no interest in woman and has enough obsessive compulsive quirks to astonish anyone. While I don't think his quirky nature was fully touched upon in this book, Cheney does give us a taste of some of his phobias, like earrings for example. We meet a man who was on top of the world for a portion of his life and who seemed to be on the way to making it big in the world, but then after making rather overly generous financial decisions he could never really get out of debt's clutches. He literally had to beg to borrow the money as the years got worse and worse over the years. Things looked up for Tesla for a while here and there, but he was also quite generous with his funds to help his friends financially during the Great Depression and his friends gave him the same treatment.
   
   Towards the end we get a portrait of a man who liked to make grandiose statements for what seems to be for the sake of being in the limelight again. It feels like Tesla simply missed the fame and attention, quite a different scope from the man who worked in seclusion and extreme secrecy. But his secrecy was intriguing and I think he liked to emerge to the public for attention every now and again. As he got on in years his claims didn't end in much fruition for the world, which isn't surprising since towards the end of his career and life he lived out of a hotel room without a laboratory. However, he still claimed his wirelessly transmitted electricity would work. He also ended up being wrong on quite a few things, especially when he said Einstein's relativity was not an accurate representation of our universe. Even Einstein would have wanted to agree with him, but Einstein's accuracy cannot be denied. Like Einstein they both died with dreams of a final theory, Tesla's wirelessly transmitted electricity and Einstein's Grand Unified Field theory, both of which have not been proven definitively yet. When Tesla's life was finally over his papers and research items were confiscated by the government, because amidst the grandiose claims was high grade weapons technology like ray beams and so forth.
   
   In the end we get a portrait of a man that struggled to change the world for the better and not always at his benefit. As his life ended in debt we are all left with the great boons of his inventions. Thanks to his Alternating Current we don't need a power station every two miles like we would need with Direct Current only systems. His research into radio which was eventually fully realized by Marconi made great leaps in that field. He was clearly a visionary more than anything else and a brilliant mind on top of that enthralled with electricity, machines, resonance, and the various waves that power and drive the like. I thought this book at times was a bit overly laudatory, but I think it did him justice. I get the feeling that Cheney felt a little bad for the man since he clearly does not get the same kind of esteemed recognition in America as Edison does. Some of the best tales of Tesla's life was when the two bitter enemy's fought the war of the currents, which is literally worth a book in itself. Say what you want, but in the end I enjoyed this book and I would recommend it to people who want a more in depth portrait of the man behind the inventions. Truly a great inventor who should be well known in the annals of history.



5. One of the better biographies on Nikola Tesla. My husband is a teacher and uses this for one of his text books.

5 comments about My Family and Other Animals.

1. All of Gerald Durell's writings are terrific, but the ones about his family are truly laugh-out-loud wonderful! This is a book I have enjoyed over and over, and have given as a gift many times.



2. Ever wonder what kind of person takes such an interest in every form of flora or fauna there is? One who is hyperobservant, apparently. And when Gerald Durrell turns that eye on the eccentric characters in his family and around him on the island of Corfu, you'll absolutely love reading his words.



3. This book, ironically, was on one of those horrible "summer reading" lists so many of us are forced to do in high school. It's the only one I was ever forced to read that I truly, genuinely loved. I laughed out loud literally every two or three pages, and though I have no natural interest in animals (especially insects), Durell makes his descriptions of the nature on Corfu as gripping and as touching as his descriptions of his family.
   
   It's been ten years since I first read this book, and when I get together with my old friends, we STILL argue about our favorite scenes, the best character, the most troublesome pet. This is a book you won't be able to put down the first time you read it, and will want to re-read the moment you finish it.



4. Not many adults ever reminisce about their childhood dreams. Those who do, generally label these as wishful thinking and sigh them away. Rarer are those who live lives of fulfilled dreams. Gerald Durrell, an eminent author, naturalist and expeditionist, was one of those uncommon individuals whose life's entirety was one long childhood dream come true. "My Family & Other Animals" is his most famous work, and is the first of his Corfu Trilogy.
   
   The kid Gerald Durrell, or Gerry, was eight years old when his family moved from England to the Greek island of Corfu. Through the eyes of the young, fauna-loving and ever-inquisitive Gerry, Corfu seems to be the strangest place on Earth, and all humans, whether inhabitants of Corfu or not, appear to be strange people. The book describes Gerry's meticulous observations and detailed experiences in Corfu amongst dogs, cats, toads, snakes, scorpions, owls, magpies, gulls and other creatures he keeps as pets in his house, and his family members who are bemused as well as troubled by Gerry's love for these animals and insects. Young Gerry's mother and siblings stay engrossed in their own worlds, leaving Gerry alone to spend his days as he wishes, free from burdens such as going to school and being nagged by elders. Thus begins Gerry's exploration of Corfu, starting with the garden in his villa, and eventually his domain of knowledge crosses over to the neighboring islands.
   
   The book will make you roar with laughter right from the preface itself. Descriptions of animals are unconventionally funny. Humans also are not spared. Imagine an entire family changing residence from one villa to another, just because one of them foolishly invited his friends so many that they would not fit in the current villa. After animals and humans, the third elaborately portrayed element is nature. Detailed descriptions of fig trees and setting suns create a Wordsworthian aura. Once Gerry sets on describing some of these, he can be drawn back only by some exquisitely crafted squirrel or a raucously howling dog.
   
   The best way to savor the book is to read it over several sittings, by allowing the excessive laughter to brighten many a dull day. An enlightening perspective of the work can be seen through Gerry's eyes. Animals, unlike humans, know exactly what they want. They are easier to please and easier to be understood. Most importantly, animals are easily befriended and are almost always loyal. When the book ends, it feels as if an intimate and jocular friend has left you forever.
   
   "My Family & Other Animals" is a beautiful comedy, and is highly recommendable for reading by people of all ages.

5. This book is very funny and enjoyable. It tells of the author's years as a boy spent on the Greek island Corfu. I love the stories of his adventures raising and studying the wildlife on the island. It is also funny because he recounts tales of his strange family. At some parts I found myself laughing out loud. You should read this book along with Birds, Beasts, and Other Relatives.

5 comments about iWoz: Computer Geek to Cult Icon: How I Invented the Personal Computer, Co-Founded Apple, and Had Fun Doing It.

1. I enjoyed reading this book but like others, I found it annoying at times. It is an autobiography. Most of the book is about boring details of Steve Wozniak's life. His account of how Apple Computer started and how the Apple I and II where created is very interesting, unfortunately it is a very small part of the book. It was very annoying reading his constant bragging about how humble he is.
   
   The book gave me a better understanding of early PC history and the history of Apple. I also wanted to learn more about a guy I consider a hero. I did learn more about Woz but I must say that based on what I learned from this book I respect him a lot less than before.



2. I'm a mac user, and I always wanted to know how Woz lived all Apple's building process.
   It's a great biography and really enjoyable to read. All is written in a very friendly way.
   I really recommend it. It's a piece of computer history, I think, all geeks should know.



3. This was an outstanding autobiography that gave me real insight into Steve Wozniak's life journey and thought process. Most interesting and prevelant was the invention of the first PC, but the book goes beyond that.
   
   As a tech person myself, I really liked how he would stop and describe how things worked as it related to how it shaped his life. Some of it was interesting and easy to understand (e.g., why twisted pair wire is twisted) while others were interesting but mostly went over my head (e.g., the intricacies of a complex circuit board). But I even enjoyed the stuff that went over my head.
   
   Some of the other reviews trashed this book because they thought he was too full of himself or they thought the book was written "at a 6th grade level". #1 - it's an autobiography - what do you want him to talk about? #2 - he invented the first personal computer - if anything I think he downplays his role too much (it's not like the PC has any impact on modern life, right?). #3 - the book's style is just about perfect if you ask me. If you want an autobiography that reads like a high-brow novel, then read one about a novelist. For me, this was perfectly what an autobiography should be: a behind-the-eyes look at someone truly interesting and impactful on everyone's lives, written in his own words.



4. Steve Wozniak spends a lot of this book detailing so many examples of his relentlessly positive attitude, his relentlessly great time growing up, and his relentless enthusiasm for all thing electronic. He does a good job in some early sections explaining movements of electrons along currents at their both basic level, which is appreciated by non-engineers. I was put off by his side story of opening/running the Mayfair theater in a "low-income" area of Silicon Valley and having to paint the bathroom black to stop the graffetii. I grew up in what he probably thinks are "low-income" areas of Silicon Valley, i e your house is under $2 million bucks, and I was pretty offended. Wow! We weren't super-rich and I never graffettied anything! This typifies the snotty elitist attitude of people in that area and reminds me why I high-tailed it for Sin City. Too bad that one of the men who built and contributed so much has this attitude as well. Stop playing to both sides of the fence, Woz. Your products are great, but your book needs some de-bugging!



5. iWoz is an interesting book about the man who almost single-handedly started a revolution. I loved reading about how Woz designed the Apple I and Apple II computers. He's a guy that's on a whole different level than most engineers. I'd love to meet him someday. If you are interested in how personal computers came to be, I highly recommend you read this book along with "Fire in the Valley" and "Hackers". Also, buy the DVD "Pirates of Silicon Valley". Thanks Woz for bringing computers to the masses!

5 comments about Galileo's Daughter: A Historical Memoir of Science, Faith, and Love.

1. I had expected a fictionalized narrative following the daughter of the famous astronomer. What I got was a detailed biography of Galileo himself. However, I still continued reading to the end.
   With more warmth and humanity than your average historical account, Sobel's story weaves the life and family of its subject in among the facts of his life. Such things as his recurring illnesses and his struggles with the church authorities are brought to life and made more interesting.
   I recommend this book to anyone who is interested in the life of Galileo, or anyone who is interested in the day-to-day activities of Italy in the 17th Century.



2. I've got a secret. This book is not really about Galileo's daughter, Virginia. It is about Galileo and his life and times as seen through letters from his daughter to him (the letters from him to his daughter were destroyed). As a book about Virginia, it is largely uninteresting and unenlightening. As a book about Galileo, it is terrific. Dava Sobel captures the essence of Galileo's work and his fight with the religious authorities. My emotions as I read the book were: enlightenment in that it shows Galileo to be a far better person than I had given him credit for; sadness because of how he was mistreated; amazement for the honor he showed in all his dealings; and frustration at how much science was held back by religious authorities. And it puts into perspective how little my own daughter actually demands from me. I strongly recommend this book and I look forward to reading other of Sobel's works, including Longitude.



3. GALILEO'S DAUGHTER
   By
   Dava Sobel
   (Penguin Books 2000)
   Sour Marie Celeste was the illegitimate daughter of Galileo Galelei - the eldest of his three, and only, children At the age of 13 her father had her admitted to the convent of San Mateo in Arcetri, where she would remain until her death at the age of 34 in 1634. Once admitted, or shortly thereafter, she started writing letters to her father - the most loving, beautiful, intelligent letters I have ever read. There aren't too many of them, but they have been preserved and form the excuse (if that is the right word) for this book - which is a part history of the life of Galileo, part comment on his times and a setting to publish the letters chronologically along with and in tune with events in his life.
   Every school child knows something about Galileo - whether it was his "invention" of the telescope (he didn't invent it; he improved it immeasurably) or his "discovery" of the fact that it was the earth which revolved around the sun rather than vice versa - and this too was wrong, He didn't "discover" this. The sun-centered universe (heliocentered) had been discovered and described by Nicholas Copernicus (1473-1543) in 1543, 21 years before Galileo was born in 1564. Using Copernican theory Tycho Brahe (1545-61) had fixed the positions of may stars both as to distance and location and Johannes Kepler (1591-1630) had established the planetary motion of the planets - or most of them. So it wasn't what he invented or what he "discovered" that eventually got him into trouble with the Catholic Church, it was the fact that he was by far the most gifted and the most prominent man to have advocated - or thought to advocate - the heresy of a heliocentered universe.
   He had been a star from the start, one of the most gifted mathematicians of his age or any other, one of the few who, instead of taking things as they are said to be, tried to find out how they really are. And thus was one of the first true scientists, a man who dropped balls of different weights from the tower of Pisa, who rolled balls of different weight and different sizes down inclines of different pitches, who measured the tides, floating bodies - always studying motion and/or the laws of motion - and almost all of modern physics is the study of motion whether it's string theory - action at a distance - or general relativity or the measurement of the effect of a collision of protons in the CORE tunnel in Switzerland this summer.
   He was always an academician, teaching mathematics at the University of Pisa or Padua or being the resident mathematician and experimenter for one of the Medici's. And on retainer to the same. He was always ill. He never married. His work was his spouse. However, he recognized his three children by his liaison with the beautiful Marina Gamba of Venice. Domestic life was not for him. To the end he worked and thought, living as a guest or retainer in many ducal palaces in Tuscany and Rome. He lived as an untitled man at the highest level of worldly or ecclesiastical aristocracy. He made enemies - many of them - but he persevered and died in a kind of house arrest at the age of 72, still working and under banishment for daring to support the idea that the earth moved about the sun which the Catholic Church, relying on Aristotelian and Pythagorean thought and on the literal word of Holy Scripter believed as holy writ that it was the sun which revolved about the earth.
   I have just spoken of his many enemies and of the ducal residences in which he often made his abode: and the book is full of this detail - too full in my opinion. It would have been better if much of this had either been omitted or if Ms. Sobel had taken the time to tell us something about the governance of his time, I would have been much better informed had I known something of the Medici's or the Doges of Venice or the politics of the Popes who were involved in his life. And I would like to have known more about how people lived in his time.
   Similarly I would have liked to know more about convent life. There is enough in the book to indicate that it was perfectly dreadful -cruel, inhuman by our standards. Hared work, cold water, bad food, no rest, small quarters, iron discipline and no sleep. The Hanoi Hilton in San Matteo. Why would anybody lived this way? And why did Galileo put his daughters "away" at age 13. He robbed them of a life! (The excuse given by Sobel is that he learned he had known enemies in court because of his success and wanted to protect them; but this doesn't wash with me. All he had to do was to acknowledge them and, as his heirs, they would have properly evaded his enemy's attempts to take his property. I think he put them away because he was selfish. He didn't want three illegitimate children to be staining his record as he surged his way upward, buoyed by talent and reputation.)
   As Galileo stepped through his professional life he wrote to Sour Marie Celeste, but his letters did not survive. Her replies and her spontaneous letters to him did survive, however, and manly of them are quoted here. Would that all children would love their father so much. Would that any one of us would have a child as intelligent, as articulate as she. Would that she were here today - or those like her - to call our attention to enduring love as contrasted to the conditions in which we live.
   There are a couple of other comments I want to get down here on paper before I quit. First - about Galileo's "Trial". It is covered accurately and well in the book. In brief Galileo had published in Dialogues the essence of Copernican thought spoken through the mouth of a neutral that was just saying what it was. Then there were two characters, one of which was Galileo under a false name, who discussed it. Thus he never on paper espoused the Copernican heresy. He just said what it was. He thought he had a deal with Cardinal Bellarmino (later Saint Bellarmine) that as long as he didn't teach or espouse it he was not in conflict with Church teaching. However, 15 years later he fell out of favor with Pope Urban VIII. His enemies in the Vatican called on the Inquisition to question him and it was as the result of this that he was sentenced to house arrests.
   The trial is well covered in the book, but I wish Sobel had told us more about the Inquisition, how long it lasted, what it did, what procedures were followed, how it was independent (if it was) of the Vatican. What was the Index? What happened to people who wrote things that made their way to the Index of banned books? What kind of books? How many?
   I also wish she had told us more about the thirty Years War because it is frequently mentioned and apparently played a direct role in the attitude of the Catholic Church at the time.
   Woven through out this history of Galileo's life and the beautiful love expressed by his daughter (who was every bit as bright as he was) is the conflict between science and religion. Sobel never addresses it. But it's pretty clear to me. Religious belief cannot overrule, change or ignore true scientific discovery. And the greatest conflicts in this area have been the Galileo incident with respect to the heliocentered universe and Darwinism. God made the world and He made the rules of nature and God doesn't bend, break or ignore His rules because they are contrary to the ideas of His people



4. This book must be read if not for the depth of the actual telling, then for the elegant writing itself. The intertwining of primary source material and the author's own pen is done beautifully. The story's theme of the supposed clash between faith and reason/ science is as relevant today as it was in Galileo's time. Food for thought.



5. My real issue with this book is that Sobel's writing leaves me cold. I had avoided reading this for a long time because I had not really enjoyed Longitude. But countless critical raves and the response from friends caused me to decide to give Galileo's Daughter a try.
   
   The subject matter is interesting enough. The book is very little about Galileo's daughter and is more a book about the man himself. That is not really a bad thing, since there is sadly not very much to know about Suor Maria Celeste. The episodes Sobel chooses to highlight are interesting, and I believe she succeeds in making Galileo human to the readers.
   
   I would be hard pressed to say what exactly it is that I do not like about Sobel as a writer. It is not something that I can easily articulate. I think that it has something to do with the fact that her prose feels like an overextended magazine article. Both in Longitude and in this book, I felt as though the material were too thin for the weight that she was trying to hang on the pages. I am not sure that this is true, and suspect it may have something to do with the structure. In any case, with both books I had the experience that I was quite impatient with the prose even as I was interested in the material.
   
   If you are interested in scientific history and in the mood for some reasonably light reading, then my review should not discourage you from picking up Galileo's Daughter. Myself, I am probably going to avoid Sobel in the future.

2 comments about A Stubbornly Persistent Illusion: The Essential Scientific Works of Albert Einstein.

1. A Brief History of TimeGeorge's Secret Key to the UniverseArchimedes to Hawking: Laws of Science and the Great Minds Behind ThemEinstein: His Life and Universe
   
   Imagine where we would be if these two, Einstein and Hawking, had worked together!
   Hawking puts information into the theories and makes for a more complete understanding into Einstein's times and mind.
   A very good book, well versed and full of information, layed out and explained in their own words.



2. The most highly celebrated and recognized scientist alive today, Stephen Hawking has assembled, in this volume, highlights of Einstein's groundbreaking scientific works, such as his Special Theory of Relativity (1905) and his General Theory of Relativity (1915).
   
   Also included are Einstein's thoughtful views on politics, religion, the history and development of physics, and the interplay between science and the world.
   
   In a chapter titled "Selections from Out of My Later Years," Hawking discusses Einstein's reservations concerning quantum mechanics: "Einstein pointed out that if we were able to investigate microscopic phenomena on the smallest scales, we would be able to find deterministic relations." In other words, Einstein had serious doubts about the validity of Heisenberg's Uncertainty Principle, and rejected the fundamentally probabilistic nature of reality espoused by those who held to the workings of chance and randomness at the quantum (microscopic) level. "God does not play dice with the universe," he famously opined; "God is subtle but he is not malicious." He held adamantly (some would say stubbornly) to his belief that physical reality is, at bottom, deterministic.
   
   Hawking gives brief introductions to each of Einstein's papers, thereby providing helpful historical and scientific perspectives.
   
   Einstein once said, "Do not worry about your difficulties in mathematics. I can assure you mine are still greater." Yeah, right! Einstein is much too modest.
   
   In a sense, however, Einstein is correct. Although this volume is replete with mathematical equations, one can read between the lines and gain an improved understanding of his revolutionary theories of spacetime and gravitation.
   
   Einstein makes us smile with his wry humor: "Today I am described in Germany as a 'German savant,' and in England as a 'Swiss Jew.' Should it ever be my fate to be represetned as a bete noire, I should, on the contrary, become a 'Swiss Jew' for the Germans and a 'German savant' for the English."
   
   The book's title of comes from another Einstein quote, "People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion."

4 comments about Archimedes to Hawking: Laws of Science and the Great Minds Behind Them.

1. This was the first book by Cliff Pickover that I've read and it's made me want to read more. I'm giving this book five stars because it was so well-written and interesting, and the subject matter was presented with such creativity it was a fun read for someone like me, who does not have a background in science or mathematics. I admit to briefly skimming over the physical laws, but I devoured the biographical sections on each of the lawgivers and found their lives truly fascinating. I also appreciated the "Further Reading" and "Conversation Starters" in each chapter. The author noting current events in the world at the time each lawgiver was alive was very cool, an excellent touch, for it provided perspective on the big picture and made their accomplishments all the more remarkable (if that's possible). Often while I was reading this book I thought of my teachers in high school and wished they'd had some of Pickover's storytelling skills, because knowing about the lives of lawgivers would have been a great motivator. For that reason I think teachers would find this book valuable, but it's also a book for everybody, and I'd recommend it to anyone who is interested in the quirky, remarkable people who changed the way the world thinks.



2. Science is often erroneously, I think, seen as "cold and austere like sculpture" as Bertrand Russell once described the field of mathematics. But, the story told by Pickover of some of the great laws of science and the lawgivers who gave us these laws is much different from that. It is a story of incredible human passion, of people like Michael Faraday who described electricity as "the soul of the universe", the modestly educated Pierre Curie who won a Nobel Prize in physics, and Robert Hooke who invented the hygrometer to measure humidity after observing that the hairs of the beard of a goat would bend when wet and straighten out when dry. Other figures endured bizarre afflictions, strange religious beliefs, harsh criticism from rivals, and even simultaneous discoveries of their own work by others. Yet, they triumphed and continued in what Murray Gell-Mann described as "the most persistent and greatest adventure in human history, this search to understand the universe."
   
   Pickover describes the laws, the lawgivers, and the nature of scientific laws in a brisk and lively pace, and peppers the book with loads of color and black and white illustrations. And, since you will doubtlessly want to learn more, there is a generous supply of references, both in print and on the internet. Science is dull and dry - nah, don't believe it. It's full of life and human drama when Pickover tells the story!

3. Cliff Pickover's newest book is both significant and unique. The blend of factual data and biographically interesting stories of the scientists lends itself to being appealing to a wide variety of readers. No other book that I'm aware of covers both a wide range of scientific laws in addition to covering the back story behind how those laws were developed. Michael Guillen's Five Equations That Changed the World is similar in both interest and in target audience, but the Pickover book is covers many more laws and people. Jennifer Bothamley's Dictionary of Theories, in contrast, has a much wider scope (and including non-scientific theories), but the special interest of the back story is absent, again distinguishing the Pickover book as distinctly different.
   
   Archimedes to Hawking can be enjoyed by everyone with a curious mind: why DO we name some physical laws after people and some not? how did these geniuses live, and what prompted them to do the work in their fields? how did they stumble upon a brilliant concept, and what struggles did they go through to prove it? All written with Cliff's unique and entertaining style.
   
   In all, it's a brilliant book that I would recommend to anyone. I plan on recommending that my science teachers have their students buy the book for summer reading for our high school science courses.



4. This is Dr. Pickover's first scientific book since his A Beginner's Guide to Immortality and The Mobius Strip writings of 2006. After over a year of pursuing science fiction, the author has provided us with a work that was worth waiting for. This is his best yet.
   
   Archimedes to Hawking is no dry listing of scientific laws. Yes, it does have the important laws of science and the runners-up which Pickover generously calls the "Great Contenders." The reason that the book runs to five hundred pages is that Pickover describes the lives and works of the lawgivers. These are not just people who showed up. Their biographies show that they worked at it. "Genius is one percent inspiration, ninety-nine percent perspiration."
   
   Although the illustrations appear to be more for decoration than explanation, some are quite stunning. I particularly liked Bode's Virgo and Hooke's Flea, even if they have nothing to do with the laws named for those two. More illustrations like those would have been nice.
   
   The author's approach is interesting. The laws are arranged chronologically. Archimedes is the first, but we have to skip almost two millennia to the Renaissance to find the next. The Industrial Revolution then brings the bulk of the science. There is very little past the turn of the twentieth century. Only three of the scientists named in this collection are still alive. Perhaps we have stopped naming scientific laws after people because we regard the laws of nature more as discovery than personal invention, or maybe it is that we are so expectant of future refinements that we now distrust the concept of the immutable law.
   
   The geography of the lawgivers is mostly European. The bulk of the laws are attributed to French, English, and German physicists and chemists. Americans are fourth in number, but only if you include the runner-up category.
   
   Although Pickover is not a physicist by training, he shows that he understands the thought process of the physicist. He shows their quest for understanding of the principles of the universe, the search for the beauty and symmetry of nature.
   
   Even more, Pickover has learned to think like a physicist. Pickover gives a rational explanation for his inclusion of works in the great laws and the runner-up categories. Many people may be surprised to find that Maxwell's Equations do not have a chapter of their own but share the Faraday chapter, while relatively obscure works are included, even one of the runners-up that includes my name. Pickover explains that the individual laws that make up Maxwell's Equations were developed by other people: Ampere, Faraday, Gauss. For a book like this it is necessary to make choices. The author explains his reasoning in a convincing manner. You may argue with his choices, but I think that if he errs, it is mostly on the side of inclusion, not exclusion.
   
   I do not think that you have to be a physicist or chemist to appreciate this book, but some formal science training may help you to appreciate the simplicity and beauty of the equations. I see this book becoming a standard reference work for those who study the physical sciences or the history of science. Or you may just like it for the joy of the science and the history.

5 comments about American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer.

1. I cannot find this book. It came with one other book that I am now reading. I can't remember if this book was actually including in the package (as indicating by the packing statement)and it got immediately misplaced or accidentally thrown out with the package or if it was inadvertently not included in the package when it was sent to me.



2. Just imagine, an American kid, rich for the times, with a saintly brother, the mind of a polymath, and a knack for atomic physics. Sounds like trouble? It wouldn't have been if he had proceeded down the Nobelist path making his name a household word in thirty other academic households. Fortune would have it that he be associated with an Army General from the Corps of Engineers who had just constructed the Pentagon. This unlikely pair were charged with creating a nuclear bomb. (Thank God Hitler didn't couple Klaus Werner Heisenberg with Albert Speer giving the Germans a bomb in 1941) Oppenheimer and Groves got together the world's best talent in a pasture in New Mexico and with branches all over the place and made the bomb. It worked!
   What a nice story. One would hope that Oppenheimer would find a sinecure and while away the rest of his life teaching, further extending his education, and becoming a scientist statesman. An immortal victory.
   But there was a problem. In the thirties both brothers had feelings about social justice for the working class in California. Neither of them seriously considered armed overthrow of the government, direct action, sabotage or traitorous conspiracies. They were simply parlor pink in the midst of the depression. Sadly, J. Edgar Hoover (in addition to his other activities with the ubiquitous Clyde) took on the issue of spying on American citizens whom he thought were security risks. Worse still, Oppenheimer's wife had lost a previous husband in the Spanish Civil War and both she and he had been dues paying members of the Communist Party. Since Hoover's illegal spying efforts were in no way conclusive, he bided his time. After the war, the government was replete with advisory groups divided between the grossly incompetent political favorites and a minority of real experts. The age of Joseph McCarthy and Roy Cohn. One of the Republican forms was a financial type far better known as a fund raiser than a nuclear physicist. Lewis Strauss, a close friend of the advertising executive (Lasker) who named Kotex and Kleenex. Strauss developed a real hate for Oppenheimer and set out to destroy him by removing all of his security clearances.
   Strauss was remarkable in that he never finished college or university but convinced Eisenhower he would be a good member of the Atomic Energy Commission.
   Oppenheimer, Director of the Princeton Institute for Advanced Study, looked on this insult to him as a deeply personal wound that never healed. Strauss was later rejected as Secretary of Commerce in part because of his own little scandals and in part because of the injustice delt to J. Robert.
   This story would be sad and humiliating to any American Scientist. Coming as it does, in the midst of an administration so studiously ignorant of personal justice with abundant evidence that it could be repeated at any time will not inhibit the courage and steadfastness that scientists must also have.



3. My father spent most of his career in nuclear engineering researching the mathematics of nuclear reactors at Brookhaven. My father had visited all the national labs and got to know all the key players in nuclear physics in the period from 1950-1970. Growing up in that environment I naturally knew a bit about Oppenheimer and Teller and others. It was clear to me that my father had sympathy for Oppenheimer and a great deal of respect. teller was viewed more as a politician looking for fame and publicity. This became even more apparent tto me when in the 1980s I saw how he lobbied the Reagan administration for research on laser based strategic defense satellites.
   
   This book is an account of Oppenheimer's life from childhood through the Manhattan Project with emphasis on the most crucial part of his career as the head of the Los Alamos Laboratory where physicists mathematicians and chemists teamed up to develop the first nuclear weapons that were used against Japan. Oppenheimer was a reserved man who did not seek the limelight. He was brilliant but his biggest asset was his management and leadership capabilities along with very good judgement, something that Teller seemed to lack. It was just the qualities of leadership that led to the succcessful development of the atomic bomb in a few short years at Los Alamos. His liberal past and pre-war affiliation with communism caused him great difficulties and some in the military feared that he was a security risk. He was continually being checked out bt J. Edgar Hoover and the FBI. Hoover did not like the appointment of Oppenheimer to the key leadership position at Los Alamos.
   
   After the war was over, strangely the man who was able to keep secrets during the crucial period of the Manhattan Projected was not trusted after the war. He lost security clearance and struggled due to the increased fear of communism from the post-war Sovuet Union including the wave of witchhunting during the Joseph McCarthy era. He was liberal and his pre-war past communist associations hurt him deeply. His philosophy on nuclear weapons and his clashes with his former colleague Joseph Teller made far a tormented post-war career. I believe Oppenheomer felt guilt over his involvement in the development of the bomb and was definitely against the arms race. This period of his life as well as his childhood was important to understand the complexities of this man. The authors do a good job of covering this and do not fall into the trap of just emphasizing the war years.
   
   This book is engaging and very successful at portraying the life character and personality of J. Robert Oppenheimer. He was the right man for a difficult and challenging job and had what it took to get the most out of an odd group of geniuses.



4. Great read. Well-written account of the man's life and the times. Obviously, one flaw with biographies is any author's infatuation with the subject. I can see as one delves into the life of such a complex and incredible person one begins to sympathize and care of the subject. Whether it is ,this, or the author's are simply very Left my only problem with the book is obvious distaste the authors have for the Right and that tends to cheapen their work. Now, I feel I need to find another account of his life in order to balance out the perspective and then draw my own conclusions.



5. This book is a quite comprehensive look at his life and took me a while to get through. But it was worth the time I invested to learn about this fascinating American. The impact he had on science obviously is huge, but I didn't realize what an interesting person he was beyond the science.
   
   The political aspects of the story are quite interesting, we don't see too many people in the science community today garnering national attention on the scale that Oppie did in his time. And his skills/passion for the outdoors was a bit of a surprise as well.
   
   Despite a few slow spots, I liked the book a lot and certainly recommend it. The pictures were also a very nice touch.

5 comments about Mean and Lowly Things: Snakes, Science, and Survival in the Congo.

1. "To understand the world, we must understand mean and lowly things." - Aristotle
   
   Kate Jackson recounts her expeditions with the flare of the best natural field scientists from Jane Goodall to Frank Buck - every bit as fascinating and courageous. Scientific exploration - hardships, danger, daring, mysteries, accomplishment, exotic cultural surprises. Including a glimpse into modern scientific camaraderie around the world and government bureaucratic malfeasance. Highly recommended glimpse of an intrepid person enjoying herself physically and intellectually.
   
   "No person who is enthusiastic about his work has anything to fear from life." -Samuel Goldwyn



2. Kate Jackson is a much-accomplished scientist at a releatively young age. I do happen to know Kate on a personal level...yet her blend of skills still amazes me. She is one part curiousity, two parts courage, and three parts intelligence. Her most impressive skill to me (with my more literary bent) is her sure ability at narrative---her descriptions pull you into the jungle and make you feel your rotting socks in the jungle heat. I think everyone should read Kate's book, as I am sure you have never met anyone like her either.



3. The reason that scientists don't know much about the reptiles and amphibians of the Congo, we learn in Kate Jackson's gripping Mean and Lowly Things is because it's a very difficult place to live and most scientists would rather work in places less remote. As a new Ph.D., Kate Jackson doesn't have much of a choice; she can go to the Congo and find snakes on her own, or she can play second, third, or fourth fiddle to some other researcher in a place with running water. Choosing the road less traveled seems to have made all the difference because Jackson turns out to be made of exactly the mettle needed for surviving in climates of perpetual damp, heat, bureaucracy, poverty, and, oh yeah, maggots, biting ants, malaria, sleeping sickness, foot long millipedes and of, course, cobras.
   
   Reminiscent of Raymond Ditmar's very out of print Snake Hunter's Holiday Jackson plunges into the submerged and remote forests of the Congo with a resolve and story telling ability that keep readers on the edge of their seats. Whether cheering along as she captures venomous snakes, or cringing as she describes discovering that maggots are growing under her skin, either way, it's a gripping and enjoyable book that makes you appreciate those people for who intentionally choose the difficult path, try harder when things seem hopeless, and persevere.



4. Mean and Lowly Things is a gripping firsthand account of Kate Jackson's adventures as a herpetological fieldworker in the Congo. While the book provides the reader with scientific detail it's written in a style which brings the experience of conducting field research vividly to life, and as such it mirrors the best travel literature. Keen observations of culture and life are balanced by frank description of the frustrations, fears and feelings of inadequacy which all travelers undergo when venturing to the fringes of the map.
   
   It becomes obvious within the first few pages that Jackson passionately believes in the epigram from Aristotle that opens the book: "To understand the world, we must understand mean and lowly things." Every page of the book breathes the excitement of discovery and the wonders of the forest, and she returns again and again to the message that there is indeed great value in studying toads and snakes.
   
   The opening chapters deal with Jackson's early years of study and work in museum collections, which provides a fascinating insight into the world of hard science with a personal angle. But we really get into the meat when she finally organizes her own expedition to a remote field camp deep in the African Congo. The skills needed on such a venture weren't taught in graduate school. They were simply things that had to be figured out for oneself through a process of trial and error. And when dealing with venomous snakes, errors can be costly. We travel with her as she learns the ropes on a trip marred by civil war, cultural barriers, and a medical evacuation due to raging infection caused by a scraped leg that came into contact with contaminated swamp water. Despite this experience, she comes away with "an altogether irrational longing to return."
   
   Jackson goes back to the Congo for two more expeditions, which are also described in the book. Her focus is on the work and on the phenomenon that she observes, and in that sense, as well as in the way she brushes aside discomfort and understates real dangers, her writing style takes one back to the great 18th and 19th century explorers who first described Africa's mysterious interior. In camp she slept beneath a patched orange tarpaulin on a simple groundsheet, covered in a mosquito net: a situation that caused her Bantu guide to quit because the living conditions were too harsh. The inedible food prepared by her cook - bland manioc which tasted like "a cross between a chunk of wood and an overcooked potato", and soup made with smoked fish which was often half rotten and infested with maggots - caused her to lose 10 pounds in the course of 5 weeks. And then there were the seemingly insurmountable cultural barriers.
   
   But all of that discomfort and frustration is eclipsed by the wonders of discovery and by the thrill of the chase. It's a message of life lived passionately, with purpose, and to the fullest. All of us could benefit from that.



5. "Mean and Lowly Things" is a phenomenal account of the trials and tribulations of herpetological field work in one of the most remote places of the world. Jackson tells her story of collecting amphibians and reptiles in the swamp forests of the Northern Congo without bias and in a way that highlights and accentuates the reasons why someone would long to camp in a secluded swamp forest to catch these creatures. "Mean and Lowly" gives down-to-Earth and easily accessible insight into the little-known area of herpetological field work. Jackson shows exactly how mundane things such as drinking water and dry clothes can be hard to come by in the field, yet how tenacity, passion and curiosity can overcome just about any seemingly insurmountable odd. From impossible government bureaucracies and maggots that grow in your skin, to traditional village customs and published scientific data, "Mean and Lowly" truly covers everything one has to deal with as a scientist in the field in an easy and enjoyable read meant for anyone. It is a wonderful and tantalizing book filled with stories that will make you want to leave for the rain forest tomorrow.

4 comments about Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time.

1. A short but well written book that sheds light on an almost forgotten man who changed the world. Interesting and fun to read, worth checking out.



2. John Harrison completes his first pendulum clock in 1713 before the age of 20. He made the gears for this out of wood which was radical for such a use, but as a carpenter, perhaps not to him---which is a mark of genius, I'd say; to reach beyond accepted norms in this manner. This he did after borrowing a book on math and the laws of motion; which he copied word for word, making his own copy. He incorporated different varieties of wood into his clock for strength and later invented a bi-metal pendulum to counteract the expansion and compression of various individual metals. He also employed friction-free movements so as to do away with problematic lubricants. When intrigued by the puzzle of time at sea and the issue of longitude he contemplated substituting something not prone to gravity, as a pendulum of course is, to track times passing. In 1737 he creates a cantilevered clock 4 foot square. This the longitude board (which had offered a cash bonus to anyone who could devise a method in which time at sea could be kept) admired. Four years later he returns with an improved model; then starts on a 3rd model, like the previous two, also a fairly large sized clock.But there exists a problem within this book: An artisan freemason by the name of John Jefferys at the Worshipful Company of clockmakers befriends Harrison and then later presents to him a pocket watch in 1753. Then in 1755, while still working on his 3rd model, Harrison says this to the Longitude board: I have..."good reason to think" on the basis of a watch "already executed that such small machines[he's referring to pocket watches] may be of great service with respect to longitude." He then completes version 3 in 1759. His fourth version appears just a year later, however, and is a 5 inch wide pocket watch! The obvious inference made by the author is that after he received the pocket watch from Jeffreys he seemingly put his version #3 on the back burner and soon started on the pocket watch 4th version. The author does not claim Harrison copied anything from the Jeffreys model, but she certainly phrases this section so as to lend one to believe that this may have been the case; that Jefferys had a hand in the masterstroke invention Harrison eventually produced in version #4. This is not true. Harrison commissioned the watch he received from Jeffreys and was based on Harrison's specifications. It seems that Harrison simply asked Jeffreys to test an idea which he himself hadn't the time to attack just then; as he was still working on his 3rd version of a table-top prototype clock. Hence Harrison's above statement to the board in 1755 whence his ideas were validated by Jeffreys. In addition, the author plays up the part of the Astronomer Royal's part in attempting to impede Harrison from convincing the longitude board of the efficacy of a time-piece solution to this problem over a celestial answer to this conundrum. The author also jazzes up the issue of whether Harrison received the prize the board promised to pay for a successful solution herein; even though the board supported him for upwards of 20 years as he pursued this quest. It's as if the author intentionally omitted some facts (that the Jefferys was a Harrison commission), and pumped up others (of a rival/foil on the board trying to impede Harrison and the compensation issue; implying that Harrison was jipped) just to make the story more compelling. John Harrison's story, however, is extremely compelling as it is and didn't need this extra spice served up by the author.Do read this (very short) book on how this Mr. Harrison solved the problem of knowing where one is when at sea; and if you're in London, visit the Old Royal Observatory and the Clockmakers museum (in the Guildhall) where you can see Harrison's wonderful creations in person. Enjoy!



3. What do Galileo and John Harrison have in common? They both had run-ins with bureaucracies that impeded the acceptance of their breakthrough ideas. And they are both subjects of books by Dava Sobel. Longitude is second book by her that I have read, the other being Galileo's Daughter. As with the latter book, Sobel combines the science of the times with a lot of background on the politics and religion of the age. She weaves these together into a coherent story that is entertaining and informative. I had never even considered that there was a ever a problem in determining longitude, so this book opened my eyes. The book I had purchased contained color illustrations that helped bring the devices that are the subject of this book to life (more can be found at http://www.portcities.org.uk/london/server/show/ConNarrative.132/chapterId/2685/Greenwich-and-the-story-of-time.html). These devices were one inventor's way of solving the problem of determining longitude at sea. Sobel covers her topic with a great deal of sympathy. Indeed, the blatant way in which the establishment hampered Harrison was very frustrating, meaning that the writing was very compelling. Interestingly it speaks to Kuhn's The Structure of Scientific revolutions, which pointed out the great steps forward in science can be accomplished by those newer to the field and that science doesn't really change until the older generation passes. I recommend this book to anyone interested in boating or science or anyone who uses a GPS device to have an appreciation for how difficult travel used to be.



4. One of the most pressing issues for early sailors was the problem of longitude. Because it was impossible to determine longitude, many ships and sailors died. Also, captains used the same routes as pirates or enemies of the state, which made it easy to lie in wait for your next victim. In 1714, English Parliament passed the Longitude Act which created an award for the first person to accurately determine longitude. Longitude, by Dava Sobel, explores the work of John Harrison, the man credited with accurately determining longitude for ships at sea.

   Today, ships have GPS to tell them where they are on the seas. But before John Harrison created his first sea worthy clock, sailors were pretty much lost at sea as soon as they lost sight of land. Watches were not accurate and clocks worked on a pendulum, which didn't help on a rolling sea. Sobel weaves an interesting tale of John Harrison, a carpenter turned clockmaker, who created an extremely accurate clock for determining longitude. But this story isn't solely about Harrison. There are others that are attempting to do the impossible as well, using the heavens to find longitude. Harrison must battle prejudice, and himself, to get his timekeeper judged for the prize (£20,000 is the award). In the end, Harrison developed several chronometers, extremely accurate and able to withstand the seas and weather, that by the 1780's all log books had an entry for longitude readings by timekeeper.
   
   This is a topic that many may not find interesting. But Sobel hasn't written an academic dissertation on the subject, she has created a highly engaging study of a man dedicated to solving one of the greatest issues facing the world at the time. Her writing style makes this an easy book to read, as there are few technical details. However, for those that need more information, she provides a rather detailed source listing. I found the book to be a fascinating look at early sailing and the answer to a problem that plagued those sailors. Also, the background on Harrison adds to the story. While he worked as a carpenter, his knowledge of wood aided him in his quest for an accurate timekeeper. His chronometer was accurate to less than a second, in the 1700's, when other, more learned clockmakers could only be accurate to 15 minutes a day (plus or minus).
   
   This is a very good, enjoyable book on a fascinating subject.

5 comments about My Inventions: The Autobiography of Nikola Tesla.

1. I'm really a fan of Tesla and this book was a good view into him as a person. Although the exact same pages of this book can be found in the end portion of the book "The Nikola Tesla Treasury" and I highly suggest that book over this one.



2. Not what I expected. His childhood years were interesting. But I didn't finish it - and I really like books about inventors. Not enough info. His writing style is a bit hard to follow. Better to buy a bio written by somebody else. I rate it "One Induction Motor".



3. You really get a feel for the way he thinks, and his eccentricities from this book. If you want to know what it would feel like to talk to him then read this book. If you want an in depth biography I recommend Tesla: Man Out of Time



4. Good book, it seems like its written funny,not sure how to explain it though. Alot of uncapitalized i's, was it even proofread?



5. This is a great book which surfaces Tesla's biography, image of himself and of his internal mental processes. The way Tesla outlines his own internal thought processes and psychology is deeply interesting. I think anyone who aspires to be an inventory would be inspired by reading this book. Tesla's explanation of how he ran experiments in his mind without needing any interfering apparatus is inspiring to those who enjoy theorizing and exploring reality.
