Physics can be difficult to learn when theories and formulae are thrown at you with no historical context. You begin learning about motion, and then electricity and magnetism, and it's almost impossible to see a coherent connection between the ideas. Many people have heard of relativity and quantum theory, but do not have even a general notion of what they aim to explain.

Like mathematics, you can learn physics without knowing about the people behind its development (though you will encounter many of their names in important expressions), but it never hurts to study how such ideas began, and how they came to be what they are today. Einstein and Infeld's book is aptly titled. They show how and why certain concepts came into being and what significance they hold. Beginning with "The Rise of the Mechanical View," they describe vectors, motion, forces, and energy. With "The Decline of the Mechanical View," they show how the behavior of electricity, magnetism, and light waves poses problems for the mechanical view.

The next two (and most interesting) sections explore field, relativity, and quanta, and how they have proved more accurate in describing physical phenomena than what was previously known. Einstein and Infeld describe everything with a minimum of mathematics so that anyone with an interest in the development of physics can understand the contents. Although such math is necessary for a precise understanding of physics, the aim of the authors, which they frequently repeat throughout, is to give the reader a broad understanding of the general underlying principles. They have succeeded in giving an account of where the human construction of physics started, what has been covered since then, and where it is heading. It is a simply written book, suitable for readers who don't know physics and want to learn, but also helpful for students of physics who want to see a broader picture of its evolution.

It has been two years since I read this book - but it impressed me so that I recommend it highly. It is quite readable without being condescending. It uses clear text and simple but essential diagrams to explain how physics evolved from Newton's work through to Einstein's. Only very basic mathematics is used (Can you add,subtract, multiply, and divide?) so the book is approachable by any reader who has at least a vague rememberance of physics. It's the best book of its type I have read.

This is the best short book that I know of on the history of physics--equally useful for the casual observer of science and the serious physics student. Einstein is capable of presenting the basic ideas of physics in a way that is succinct yet complete--and he never loses sight of the broad, revolutionary ideas that make the history of physics so exciting. This is undoubtedly because physics actually IS exciting for Einstein, and this excitement comes through in every page.

This book reads as if Einstein thinks of physics as a really good story--complete with all characters and action of any good story--that he really wants to share with his reader.

I have just acquired a copy of this book from a second-hand bookseller, and am astonished to find that it's out of print and there has apparently never been a paperback edition. I followed the Strangler case as each new murder was reported in the UK press, and it remains the archetypal horror story for me because it proves conclusively that one isn't safe even (above all) at home. I also read Gerold Frank's account of the affair very soon after it was published in the UK and re-read it last year; I have the "confessions of the Boston Strangler" in French translation.I have never been even half-way convinced that DeSalvo was guilty, and I always doubted that only one killer was involved. (The "psychological explanation" cited by Frank as to why the killer suddenly switched from older to younger women struck me as perfectly ludicrous 30 years ago, and many recent books on profiling have merely strengthened this view).

It would be easy enough to write a book which simply challenged the official solution, but that is not what Susan Kelly does. She provides overwhelming evidence not only to demolish it, but also to explain how and why it came about in the first place. This is a book with an index, a bibliography, acknowledgments which help the reader by indicating the author's sources (most acknowledgments seem only to explain who made the coffee and watered the plants while a book was being written) and careful indications of when exact quotations from transcripts are being used. It assumes no previous knowledge of the case or the "cast", and its procedural details are much clearer than Frank's. Also, Susan Kelly is literate, and she has a dry, ironic sense of humour.

I checked the book's listing in Amazon because I wanted to know what other people thought of it. I had hoped that, unbeknown to me, the Boston Strangler affair had been rewritten and DeSalvo belatedly exonerated. Apparently this is not so. I would be interested to know if anyone (apart perhaps from F. Lee Bailey, Esq.) has challenged Kelly's arguments and, if so, on what basis - though I doubt whether that could be done. If it can't, I hope the book will soon be reissued and properly publicised. It would also be interesting to have someone re-open the only murder case in which DeSalvo was certainly involved - his own.

I was barely a teen in the Boston area when The Boston Strangler murders started. Recently DeSalvo's family asked to have the case reopened, no doubt due in part to this book. Their request prompted me to find more info, if any, about this case and I found this book in a library. Could not put it down. Expected the usual fact-packed but dry true crime book. Kelly has not only written a very readable and entertaining book, she has also made her case, namely, that there was more than one "Boston Strangler," and that DeSalvo was not one of them. Who some of the Stranglers might have been makes for a chilling surprise I won't give away here. Also, it provides a fascinating glimpse into the early career of F. Lee Bailey. Wish I could buy this book. It's a keeper.

I read this book several years ago--and I am shocked to see it is no longer available. This is the definitive examination of the case: author Kelly looks at all the evidence, the sensationalism, and DeSalvo himself, with a scholar's objective eye. Her conclusions are disturbing and cannot be ignored. If you want to have a genuine sense of the terror in Boston from those days, this is the book. Some publisher ought to put this book out and give it the attention it so deserves.

I've never, ever, in all my life read anything like this book. And I've read everything. Most of these "I saw heaven" books are weird and poorly written. This book, on the other hand, is in a class all its own.

I find Sister Rountree's account to be credible and written with a keen matter-of-fact style. Sister Anna graciously spares us from religious cliche and Bible catch phrases. Instead, she's direct and unapologetic, adding very little personal interjection. She kindly tells us what she saw and experienced and lets us have it as close to first hand as possible without actually being there ourselves.

This masterpiece left me numb for days--literally. There's so much in here to digest. I read it straight through in one day. I'm about to read it for the second time. I'm sure I'll read it a few more times, too.

Folks, there's nothing out there in the same neighborhood as this book. If there is, please email me!

Very few people have had a visit to heaven of this magnitude. Anna has passed on to us an oracle of God - this is modern day scripture, a book of revalation in this day and age. Every Christian serious about God must read this book. I have read numerous near-death accounts and heavenly vision books - this is maybe on the top 3 for me.

words don't discribe the awe of this account of our heavenly home. The sweet love of Jesus our purchaser and our fathers love for us his earth family.

You will want to own this book, not borrow it, because you'll want to read it over and over again. It's truly a classic, and not just for homeschoolers. This book for me was an experience and inspiration, not just a "read." It was a window into my own soul and the souls of my children. I loved my children more as I was reading the book (if that's possible). Though there are plenty of practical ideas on homeschooling in this book, the author doesn't stop there. He also indirectly poses answers to questions such as: How can homeschooling increase the quality of life for everyone in the family? How can the process of homeschooling improve one as a human being? And even, how can homeschooling make the world a better place - not after the homeschooler has grown up and starts using his or her education, but as, well, a side effect of the homeschooling process?

You could substitute "raising children" or "living life" for "homeschooling" in the above questions, and the answers given in the book are just as relevent. That's why this book is not just for homeschoolers, but for anybody interested in those ideas. Like another reviewer, I found the social studies section alone worth the price of the book. Because the book is written as a series of essays on numerous topics, you can mostly likely find something that will resonate or be helpful at any given time. I've read dozens of books on homeschooling and education, but this one has a place reserved on my shelf with a handful of others that are true classics and that I will read again and again.

A classic work. A unique, wise, witty, literate, useful, philosophical, and thought provoking journey for homeschooling parents and thoughtful educators. There isn't another comparable work available for those seeking to enrich and expand their homeschooling journey into a life altering experience for themselves and their children. This book carries the ideas brought forth by John Holt and John Taylor Gatto to another level. This book is a wonderful combination of the practical, with ideas you can use, and an example of how to incorporate the aesthetics of family learning into the realm of daily life with the world as your meeting house.

This is a book not only for homeschoolers but for anyone who has anything to do with EDUCATION be it: a princple, teacher or school bus driver or a parent. A delighful almost poetic read it is also,moving, life altering and inspiring. No library, personal or instituional should be without it.

With a sence of humor Mr. Scholl does a great job of educating others about rock art.

In an introduction chapter he discusses what rock art is and types of rock art. He discusses what rock art means and refers you to other well written books. He also provides lists of emergency equipment, camping equipment and more that you should consider taking as you begin looking at rock art.

In the next chapters he tells where to go to see rock art. He also instructs the reader about the expected behavior, tours to take, and more.

There are directions for taking pictures of rock art and explanations of clothes to wear, weather, and even a few recipes for crockpot cooking... so you can cook while you are looking and come home to a nice meal. Great!

This is a very exciting book. It made me want to jump out of my seat and go looking. The pictures are nice. His enthusiasm is catching and the format is easy to understand. Well worth the money.

Enjoy

IF MY HOUSE WERE ON FIRE THIS IS ONE OF THE FIRST BOOKS I'D SAVE! IT IS FUNNY, CREATIVE, PRACTICAL, AND VERY WELL ORGANIZED. EXPERIENCED HIKERS, BEGINNING HIKERS, OR ARM CHAIR TRAVLERS - YOU WILL LOVE THIS BOOK - AND IT JUST MIGHT GET YOU OUT OF YOUR ARMCHAIR.

With the exception of the short dictionary at the back of my Greek New Testament, no tool has been of more use in my study of Biblical Greek than this lexicon.

More than just a dictionary, the strength of this lexicon is that it gives both specific meanings of words in context as well as a knowledge of the shadings of meaning that a word carries throughout the Bible. This moves the student from a general grasp of a thing to an attentiveness to the precise way God has made himself known--there is nothing quite like it.

As other reviewers have noted, this is probably not a good place for beginners hoping to do a word study to jump in. I'd recommend Vine's for that. I also recommend that those serious in the study of Biblical Greek use this book in conjunction with a Greek New Testament, Mr. Mounce's Grammar (his lexicon is handy too), and Zerwick's Grammatical Analysis. This broad group of tools should help keep you from falling pray to a single interpretive spin.

Don't let its size and price scare you off--this book is essential for the student of Biblical Greek.

The third edition of this famous Greek-English Lexicon does not disappoint. It is a significant improvement in at least three respects. First, specific Greek words have been given general definitions even where the word covers a wide semantic domain. This was not the case in previous editions where the reader was left with the meaning of a word only in its particular occurrence. Now readers can draw some conclusion about the basic meaning of any given Greek word. The approach suggests a regression in the approach to biblical words spearheaded by James Barr in his "Semantics of Biblical Language" and a return to the approach of older lexicographers to the effect that words have meanings. Second, the range of Greek authors has been expanded and now includes more noncanonical (especially apocryphal) Greek writings of special interest for the study of early Christian origins. Third, the type set and publication of this edition is dramatically improved, making it as sheer pleasure to handle and read. The second edition suffered from typeset that was too small, and lacked bold catchy print for the words themselves. Readers who own the second edition will want to upgrade for this reason alone.

There are two drawbacks. The first is price. This is an expensive volume, but perhaps that is to be expected. The second is that I noticed several examples of errata. No doubt these will be removed with each new printing.

If it were not for this lexicon the serious, but "linguistically challenged" scholar, would have a hard time understanding the correct usage of just about any Koine Greek word. By comparring the usage in the NT and the writings of Josephus and early Christian writers, we can discern how the early church used a certain Greek word, in fact, what the Apostle's intended to convey in their writings. No other lexicon in existance does this. If there is such a thing a "truth" this lexicon shows what the early church taught that it was. Throw out all of your other lexicons and buy this one.

Lincoln Barnett has created a master piece of scientific literature for the uninitiated to the world of scientific thought. I feel that this book was written in a way that any person who reads it can grasp the basic concepts of relativity and electromagnatism. It should be required reading for all high school students with the anticipated result of turning out many more scientists and engineers in this country. I have owned the book for more years than I can remember and have read it and reread it multiple times and over time have given copies to youngsters that I thought had a potential scientific inclination. I still have a copy on hand and do not understand why in is not in print today.

I've read just about every book on Einstein's theories meant for the general reader (as well as not-so-general reader) and this is the clearest, most concise, and best-written book ever done on the subject.

I read this book almost 30 years ago and it's good to see from the other reviews here that people still know about this terrific book. It's a little masterpiece of science reportage done during a time (1950) when there were very few talented writers doing this sort of thing (unlike today), and in which there wasn't much demand for science writing in general. Lincoln Barnett was a gifted journalist and he produced a little classic in this book.

This is absolutely the best book on any scientific topic intended for the general reader that I have ever read. It is one of very few books about science I have ever read that I could seriously call a "page turner". Einstein's theories are presented in such a manner that anyone reading the book can understand the concepts without trying. I have read other books that discussed Einstein's theories, but none of them presented the ideas with such lucidity and simplicity, while at the same time not losing the depth and profundity of the concepts.

This book, even though geared for Y2K type expected disaster, still has many useful tips for emergency preparedness. I found the food prep and storage section particularly useful. Also it had an excellent section on waste disposal which is often overlooked in other emergency preparedness books. Small and portable enough to take with you.

The Y2K Survival Guide and Cookbook (Ecovillage, TN) by Dorothy R. and Albert K. Bates is not your usual recipe collection. With the savvy of environmentalists ad the frenzy of those expecting emergency, Dorothy and Albert Bates cover every area of survival and food preparation. Expecting the worst case scenario - rolling brownouts and total black outs, failed utility systems and water purification problems - this book provides natural alternatives: food storage, chlorine bleach to purify water, using wood stoves, building your own composting toilet, and gardening. There are even first aid and Morse code directions in the final pages. After coping with any Y2K calamities, it's time to cook. In between survival guidelines, the Bates' book is filled with hearty recipes reminiscent of campfire food. As computers buzz blank, you can enjoy split pea soup from melted icicles, marmalades from sun-dried fruit, or shiitake joes from home-grown mushrooms. Even though The Y2K Survival Guide and Cookbook is intended for the millennium-minded cook, it is an eccentric volume any eco-conscious chef should add to their library.

In addition to the recipes and food tips that could keep a diverse group of survivors happy for years (who wants plain ol' Chili gets that, and who prefers dishes like Rice Noodle Pad Thai will be satisfied also), there is an excellent overview of food storage techniques that includes charts I've never before seen on the shelf life of edibles, from an individually wrapped apple to nuts in airtight packages.

While Dorothy and Albert have given us lists, lists, and more lists to follow and yet others to create lists of our own, throughout their little treasure of a book is a taste of the loving, compassionate sensibility without which any attempt to survive is bound to be futile.

There is no better short book available on the mind and thoughts of Albert Schweitzer than this book. His theology on Jesus and Paul, his thoughts on Bach and organ building, his philosophy on Reverence for Life are all laid out here.

George Marshall (see my review of Marshall's excellent biography: Schweitzer) once asked Dr. Schweitzer what professors would best provide him an education on Schweitzer's thoughts. He replied that Marshall should not go to professors but "read my books! No one can express the ideas of a man as well as he has expressed them himself.... read my books".

Bob Frost of "Biography Magazine" once wrote, "Albert Schweitzer is not exactly forgotten today, but his name won't crop up in daily conversation. Fifty years ago, though, people talked about Schweitzer all the time. An American magazine selected him, ahead of Albert Einstein, as the "world's greatest living nonpolitical person." He was the subject of an Oscar-winning documentary, won the Nobel Peace Prize, and appeared on the cover of Time magazine. Fueled by idealism and burning spiritual passion, this medical missionary led one of the most intense lives of the 20th century."

Be apprized that "Out of my Life and Thoughts" is not an easy read. Dr. Schweitzer's theology and philosophy, though dense, is not incomprehensible. And due to the translation from French to English, you many find yourself reading a passage multiple times to get the gist his thoughts.

That said, for students of this great mind, this is a must read. Strongly recommended. 4.5 stars.

"Since my first years at the university I had grown increasingly to doubt the idea that mankind is steadily moving toward improvement. My impression was that the fire of its ideas was burning out without anyone noticing or worrying about it. ... What was just and equitable seemed to be pursued with only lukewarm zeal. I noticed a number of symptoms of intellectual and spiritual fatigue in this generation that is so proud of its achievements."
Albert Schweitzer was a man of action -- humanitarian, theologian, historian, musician, musical technologist, medical doctor, author, philosopher, missionary, professor, environmentalist, prisoner of war, recipient of the Nobel Prize. He writes an interesting autobiography, which is not surprising when one considers the breadth of his interests and of his achievements in science, the humanities and the arts. In his later years he was perhaps the most widely admired and respected person in the Western world.
Jimmy Carter offers a foreword in this volume; it is economical, a mere six sentences. Schweitzer's philosophical work may be well studied, but does not particularly distinguish itself in this volume (with some notable exceptions). His theological work (i.e., Christology) is generally questionable -- bound to Enlightenment fallacies of a "historical Jesus." I was happy to be concurrently reading the thoughts of a far better theologian, CS Lewis, on the idea of "discovering" a "historical" Jesus. While some of Schweitzer's ideas are [rightly] not highly regarded, his "life and thought" makes for unusually interesting biography. His "reverence for life" precept certainly has great value, but seems to be a less profoundly unique idea than he held it to be. Perhaps my view here is merely ignorant of the world in which Schweitzer lived.
He considered this book to be his best, or at least his preferred, writing, but if you are going to read only one book considering theological and historical exegetics, this is probably the wrong book. On the other hand, Schweitzer makes many observations cleanly and powerfully: "Our world rots in deceit. Our very attempt to manipulate truth itself brings us to ... [a truth] based on a skepticism that has become belief... It is superficial and inflexible." Kant had observed the intellectual paralysis of such "a skepticism that has become belief," but Schweitzer goes further, recognizing it as an even deeper spiritual paralysis.
While Schweitzer's Christology is, at the least, arguable, his firm commitment to Christ's commandment of love is a strong example of the Christian life led in the light of its Teacher's example. The author is [rightly] given to referring to Christianity as "the religion of love." In this aspect, Schweitzer at once offers the non-Christian a true image of Christianity and offers the Christian an important, if gentle, reminder. "[God] announces Himself in us as the will to love. The First Cause of Being, as He manifests Himself in nature, is to us always impersonal. To the First Cause of Being that is revealed to us in the will to love, however, we relate as to an ethical personality." And quoting Paul: "Love never faileth: but where there be knowledge it shall be done away."

Albert Schweitzer was an acclaimed organist, a world authority on Bach, a church pastor and principal of a theological seminary, a university professor with a doctorate in philosophy, and above all a humanitarian. This book gives a stunning account of how he grew into his ideals and I would recommend this book to anyone who is interested in ethics or philosophy. I was left with an urge to read more about this true human, who believed and practiced the basic principle of goodness, as I finished reading the book. Schweitzer's faith in what he believes in and how he transforms it to the needy is absolutely inspiring. The epilogue of the book is very thought provoking as it gives a clear idea of his vision and the relevance of it in the world we live in.

Read this book with Terence Mckenna's Food of the Gods. They work well together. Don't be afraid of the subject. If you've read the primary literature avoid this book unless your running a "trip" mission and you want to turn people on. These two men are giants on the subject. Forget the review. Buy the book out a repect. Schultes and Hoffman were trippy before most of us were born. P.S. All that God stuff, it's importmant but it was the thrill seeker in all of us that got us here.

The spiritual powers of healing and hallucinogenic plants are surveyed anew in Plants Of The Gods, a revised and expanded edition of a true classic which paring color photos of the plants with a wealth of solid botanical details. This revision covers the traditions of different cultures which use the plants, uses of hallucinogens in sacred rites and prayers, and solid coverage of the rituals themselves.

Plants of the Gods is a condensed ethnobotanical encyclopedia of hallucinogenic drugs with nicely illustrated cultural/art/chemical information . This book illustrates why these psychoactive plants have been so important, nay, a necessity of primordial human consciousness and experience because of their medicinal, teleportal, and communicative capabilities. It even includes a beautifully annotated color-picture field guide lexicon. It begins with a history of plant hallucinogens and then explores their cremonial/ritualistic use in various cultures around the world, creating a sense of their cultural AND artistic importance in other societies that ACTUALLY RESPECT and don't abuse them. Plants of the Gods leaves you with a sense of respect for these plants when you realize that smoking pot in some basement just to break rules is like a rites of passage sacrament practiced by many tribal cultures who know the importance of this experience which we seem to have neglected and even outlawed. Thoroughly descriptive, yet easily digestible,it reads more as a quick refrence guide /bedtime story than a book-"book", but is captivating and informatively engaging at the same time.
