The Smartest Guys in the Room: The Amazing Rise and Scandalous Fall of Enron
Today, Enron is the biggest business story of our time, and Fortune senior writers Bethany McLean and Peter Elkind are the new Woodward and Bernstein. It reveals as never before major characters such as Ken Lay, Jeff Skilling, and Andy Fastow, as well as lesser known players like Cliff Baxter and Rebecca Mark. Their prose is effortless, like a sprinter floating down the track.” —USA Today “Well-reported and well-written.” —Warren Buffett Bethany McLean and Peter Elkind collaborated on this book when they both were Fortune senior writers.
Reviews
"Many of the main characters at Enron have personalities as big someone written for fiction, so the book is actually fairly entertaining despite the dry and factual subject matter."
"Enron was a high wire act, a company on steroids, an innovator, obsessed on making deals and its stock price."
"I would highly recommend this book to anyone interested in American business, corporate greed, or the money machinations of Wall Street."
"Once heralded as the most innovative, paradigm changing company in the world was brought low by the fact its business didn’t actually do anything."
"It answers the question: Why do we enjoy so much stories about high flying business types who crash and burn by their own hubris and greed?"
"Starting with an overview of the players and the original pipeline company that later became Enron, the book takes the reader through the rise of one of the greatest house of cards in modern business history. Noting that many of the issues around Enron's house of cards were in somewhat plain sight to anyone looking for them, and the element of unrestrained greed permeated the entire enterprise, the authors bring forth a storyline that would be amazing and incredible, had it not been true. The reader will view the simplicity of structure, the need for honesty and clarity in disclosure, and the abject understanding of the economics (not the financial reporting) of the transaction is absolutely critical."
"Very interesting read, particularly if you're educated/experienced in corporate and investment finance and accounting."
"I didn't expect to be courted by an account where my emotions would hob-nobb from empathy, to skepticism, to amusement, then annoyance, followed by outrage, and finally disbelief... and not always stemming from `the cast of characters', or in this order. More so than this story could have been, and could be any one of ours', McLean and Elkind really weave an interesting personal element into this entangled economic debacle well worth the experience."

The Grid: The Fraying Wires Between Americans and Our Energy Future
Cultural anthropologist Gretchen Bakke unveils the many facets of America's energy infrastructure, its most dynamic moments and its most stable ones, and its essential role in personal and national life. The grid, she argues, is an essentially American artifact, one which developed with us: a product of bold expansion, the occasional foolhardy vision, some genius technologies, and constant improvisation. She leads readers through a history of the grid and a maze of financial, legal, regulatory, and environmental considerations with sprightly good humor . "Hopefully, Bakke’s startling exposé revealing how electricity sloshes around the country across a precarious grid will be a wake-up call." Bakke deftly shows us how a system most of us are happy to ignore--the electrical grid--is both inseparable from everything we think of as civilization and on the verge of complete failure." It's a journey through the nervous system of the modern world, one with profound implications for climate change, national security, and ensuring America’s well-lit future." For the past decade she has been researching and writing about the changing culture of electricity in the United States.
Reviews
"Author Gretchen Bakke holds a Ph.D. in cultural anthropology and is currently a professor at McGill University in Montreal, Quebec, Canada brings us this seldom told story of the evolution of an essential infrastructure. “America has the highest number of outage minutes of any developed nation—coming in at about six hours per year, not including blackouts caused by extreme weather or other “acts of God,” of which there were 679 between 2003 and 2012. “National security was threatened more by the “brittleness” of America’s electrical grid than by possible future disruptions in the flow of imported oil.”. 6. “The problem is that renewable energy adds unprecedented levels of stress to a grid designed for the previous century.”. 7. Though we tend to give Thomas Alva Edison the credit for having invented the lightbulb (he did not), he did devise something just as remarkable—the parallel circuit, one of his greatest if least lauded contributions to technological underpinnings of our modern world.”. 8. “The combination of federal and California incentives and innovative state regulations launched the wind industry in the U.S.”. 13. If ever it was in doubt, the 2003 blackout proved that at its core America’s economy is inexorably, indubitably electric.” Bonus, “In the case of the 2003 blackout the error on the grid took the form of overgrown trees and the error on the computers took the form of a line of code that disallowed simultaneous incoming data reports.”. 14. These new constructions bear a lot in common with Edison-era private plants, which generated customized electricity for a single owner on-site. Unlike Edison’s private plants, these modern microgrids can connect and unconnect as needed to the big grid (which is now increasingly known as the “macrogrid”). And, unlike any system since the consolidation of power in the early twentieth century, these microgrids work perfectly well in “island” mode.”. 18. “Anything that can be done to eliminate the necessity of diesel generators, and reduce the amount of oil necessary to feed them on the field of battle, strengthens—adds resiliency, flexibility, and mobility to—the war effort. Mobile, matte, lightweight, and diversified systems for keeping the lights on, the data safe, and the troops cool are critical to mission success. For while some of this fuel is poured into gas tanks, a lot of it is used to make electricity.” Bonus, “As a result, the DoD, which operates a fleet of 200,000 nontactical vehicles, is working to convert them all to electricity with vehicle-to-grid technologies designed in from the start.”. 19. In the final chapter, the author discusses the consumers’ personal interactions with power that may shape the grid of the future. As an example: maps of key grids, table of electrical consumption around the country, timelines, charts and diagrams showing the use of renewables versus non-renewable energy sources, etc. The topic of the grid is personally interesting to an engineer like myself but I’m very disappointed on how verbose and poorly presented the material was. On the other hand, I agree with the findings and conclusions of the author and I did learn a lot about the electric grid as en essential and pervasive infrastructure. Further recommendations: “Living on the Grid” by William L, Thompson, “Empires of Light: Edison, Tesla, Westinghouse, and the Race to Electrify the World” by Jill Jonnes, “AC/DC: The Savage Tale of the First Standards War” by Tom McNichol, “Faraday, Maxwell, and the Electromagnetic Field: How Two Men Revolutionized Physics” by Nancy Forbes and Basil Mahon, “The Man Who Changed Everything: The Life of James Clerk Maxwell” by Basil Mahon, “The Electric Life of Michael Faraday” by Alan Hirshfeld, and “Tesla” by W. Bernard Carlson."
"A good read especially in the beginning."
"In her view any discussion of the grid has to include business models, government regulations, energy politics and the public’s changing desires and expectations – all of which really are cultural. The overlapping technical, financial and social perspectives in the book provide an important picture of the incredible complexities of the grid, the daunting challenges we face in upgrading it, and the opportunities within our grasp to develop something better."
"I had hoped her book would be as engaging."
"Her book interested me because I have my own solar panels and can see wind turbines from my house; because a controversial DC power line across this state is struggling to be approved; because my hometown has its own very new backup diesel generating station. To be sure, Bakke makes some points vivid: that electricity is virtually impossible to store on a large scale; that renewable sources are ill-fitted to the grid; that the grid is interesting and complex; that trees are a bigger threat than terrorists."

What If?: Serious Scientific Answers to Absurd Hypothetical Questions
His stick-figure drawings about science, technology, language, and love have an enormous, dedicated following, as do his deeply researched answers to his fans’ strangest questions. His responses are masterpieces of clarity and wit, gleefully and accurately explaining everything from the relativistic effects of a baseball pitched at near the speed of light to the many horrible ways you could die while building a periodic table out of all the actual elements. What if there were a book that considered weird, sometimes ridiculous questions, and it was so compelling that you found yourself skimming its pages to find out what would happen if you threw a baseball at light speed? As he does in his extraordinarily popular xkcd webcomic, Munroe applies reason and research to hypothetical conundrums ranging from the philosophical to the scientific (often absurd, but never pseudo) that probably seemed awesome in your elementary school days—but were never sufficiently answered. When the goal of any researcher is to lay claim to a tiny niche in a crowded discipline, it’s hard for laypeople to find answers to the really important interdisciplinary questions. Fortunately, such people can turn to Randall Munroe, the author of the XKCD comic strip loved by fans of internet culture. while dealing with relationships and the meaning of a computer-centric life, xkcd has become required reading for techies across the world….The Internet has also created a bond between Mr. Munroe and his readers that is exceptional. But at its most ambitious, it either packs massive amounts of interesting information into a small space, or engages in breathtaking experiments with the medium….

"I love the blog and was really looking forward to this book, but buying the kindle edition was a mistake."
"This is a great way to enjoy older questions and answers over again, updated, and to share them with new people, and the new questions and answers - never featured on the website - are delightful; I won't spoil it for you, but my favorite has to be the answer to "If a bullet with the density of a neutron star were fired from a handgun (ignoring the how) at the Earth's surface, would the Earth be destroyed?" If you have even a passing interest in science and ever enjoy daydreaming about the fantastic or the ridiculous, this book is for you. Gift season is coming up; thanks to this book my Christmas shopping will be a great deal easier."
"Randall Munroe hits that oddball humor sweet spot with zany questions and actual, scientific--and most importantly, interesting--answers."
"Randall Munroe's XKCD is a cornerstone of the World-Wide Web, and he brings the same intelligence and overabundance of careful research here to absolutely hilarious (and often randomly awesome or terrible) questions."
"Best bathroom book ever... and I mean that in the very best possible way you can imagine."
"All wrapped up in a well made book sufficient for display."
"Whether it's taking a dip in a nuclear reactor cooling pool, or halting the earth's spin just to see what would happen, Monroe accepts the intellectual challenge and delivers with gusto."

"I NEVER thought of circuits this way and the author was able to explain that the active elements are the players in the story and everything else is a supporting cast. Bottom line, this is the book that I couldn't put down...and it is about some of the driest material you can find. I cannot recommend this book enough and I would pay triple just for the section where the author walks through a couple sample circuits, describes each component's function, and what would happen if that component failed."

Best Physics of Time

The Fabric of the Cosmos: Space, Time, and the Texture of Reality
Could the universe exist without space and time? Assuming an audience of non-specialists, Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. When explaining, for example, the inability to see the higher dimensions inherent in string theory, Greene writes: "We don't see them because of the way we see like an ant walking along a lily pad we could be floating within a grand, expansive, higher-dimensional space." In 1999, Greene, one of the world's leading physicists, published The Elegant Universe (Norton), a popular presentation of string theory that became a major bestseller and, last fall, a highly rated PBS/Nova series. To do this, Greene takes a roughly chronological approach, beginning with Newton, moving through Einstein and quantum physics, and on to string theory and its hypotheses (that there are 11 dimensions, ten of space and one of time; that there may be an abundance of parallel universes; that time travel may be possible, and so on) and imminent experiments that may test some of its tenets. Eighty-five line drawings ease the task, however, as does Greene's felicitous narration; most importantly, though, Greene not only makes concepts clear but explains why they matter.
Reviews
"I would recommend watching the video and read the book if you have no knowledge of the Space and time."
"Topics include (but are limited to) relativity, quantum, cosmology, etc.. More generally it deals with what the universe is, where it comes from and how it works. The only cons I find to this book are the numerous end-notes that take you all the way to end of the book (at almost every single page!)."
"Still reading the book, but so far I am really enjoying it."
"I didn't exactly find this book to be an easy read, even with its abundant analogies, but it has been well worth the effort I put into it."
"What you do want to buy this book for is the amazing way in which even the most difficult concepts are explained in a concise and clear manner. Brian Greene is a true master at explaining the intricacies of modern scientific theories to common folk such as me."
"My introduction to physics before reading this book was a few high school physics classes, two introductory classical physics classes in college, and many readings of "A Brief History of Time" and "The Universe in a Nutshell" by Stephen Hawking."
"He had a logic error in his discussion of entanglement when he attempted to explain the wave function collapse could not be a random programmed event."
"Love the corresponding show with the same title."

Reality Is Not What It Seems: The Journey to Quantum Gravity
Do time and space exist? And what exactly is reality? It's a pleasure to read, full of wonderful analogies and imagery and, last but not least, a celebration of the human spirit.” —NPR Cosmos & Culture “If your desire to be awestruck by the universe we inhabit needs refreshing, theoretical physicist Carlo Rovelli…is up to the task.” — Elle. “[ Reality Is Not What It Seems ] is simultaneously aimed at the curious layperson while also useful to the modern scientist… Rovelli lets us nibble or gorge ourselves, depending on our appetites, on several scrumptious equations. “With its warm, enthusiastic language and tone, [ Seven Brief Lessons on Physics ] is also deeply humanistic in approach, using words like elegant and beauty about a subject…that can seem impenetrably dense and abstract… Reality Is Not What It Seems takes much the same approach.” — New York Magazine. “Rovelli’s lyrical language, clarity of thought, and passion for science and its history make the title a pleasure to read (albeit slowly), and his diagrams and footnotes will allow readers to understand the material better and tackle a more expert level of insight.” —Booklist. “Science buffs will admire Rovelli's lucid writing…Cutting-edge theoretical physics for a popular audience that obeys the rules (little math, plenty of drawings), but it's not for the faint of heart.”— Kirkus Reviews.
Reviews
"Rovelli's book is a game changer The title of my review refers to the shining of light in dark places because that's how I felt when I read it. Concepts and theories that I'd struggled with through many of those previous books suddenly made sense."
"Review of: “REALITY IS NOT WHAT IT SEEMS” by Carlo Rovelli. For those who have an even casual interest in modern physics or “science” this is a truly remarkable book. Rovelli is able to take highly complex problems and express them in a way which can make them accessible to even those who think that mathematics is simply something you use to figure out how much change you should get at the supermarket or doing the highly difficult calculation of how much to tip on a restaurant bill. As most readers are aware Einstein’s theories of both general and special relativity are remarkably accurate and have passed every test to which they have been subjected as long as they apply to very large things. Quantum mechanics, the strange physics of the very small, is also exceedingly accurate in its predictions as long as it stays within its “range.” However these two great theories fail miserably when combined. Now, unfortunately, I start thinking; how many half ways are there from the point I have reached to that elusive bathroom? I had until recently mistakenly believed that the concept of space time was an invention of Einstein. The rational for this is highly complex but if this postulate had a bearing on reality could time itself actually be quantized. Thus we have removed from the equations of physics the two things that have always been considered infinite and make them finite. I doubt this will change anything in my life or yours except that I sleep better since I no longer have to worry about not being able to get to the bathroom the next morning."
"Carlo Rovelli continues the tradition from his earlier book, "Seven Brief Lessons on Physics" of combining sparkling descriptions of physical phenomena with a sensitive understanding for the form of physics and the greatness of its practitioners. As in his previous book, Rovelli has elegant descriptions of the two great pillars of physics: quantum mechanics and general relativity. This sets up the book for the second part, which is a theory of quantum gravity called loop quantum gravity. After explaining how quantum mechanics and general relativity disagree with each other in situations where it matters, Rovelli leads us through the main concepts of loop quantum gravity. According to Rovelli, the finiteness of this division enables the theory of loop quantum gravity to escape some of the ugly infinite solutions that results when one tries to combine the mathematics of standard quantum mechanics with that of general relativity. I also find it interesting that string theory which is loop quantum gravity's main rival gets little more than a paragraph, so it's still not clear why one would clearly prefer loop quantum gravity over string theory."

Homo Deus: A Brief History of Tomorrow
**From the author of the phenomenal million copy bestseller Sapiens **. **The Sunday Times # 1 bestseller**. While Sapiens looked back at our evolutionary development, this new book examines where we might be headed ( Homo Deus is subtitled “A Brief History of Tomorrow”). His innovative new book blends science, history and philosophy to explore the future of humanity in the face of artificial intelligence and examine whether our species will be rendered completely redundant.” – Cambridge Network “Spellbinding. “ It’s a chilling prospect, but the AI we’ve created could transform human nature, argues this spellbinding new book by the author of Sapiens .” – The Guardian. “Nominally a historian, Harari is in fact an intellectual magpie who has plucked theories and data from many disciplines — including philosophy, theology, computer science and biology — to produce a brilliantly original, thought-provoking and important study of where mankind is heading.” – Evening Standard. He’s opened a portal for us to contemplate on what kind of relationships we are forming with our data-crunching machines and whether ‘right’ must be determined by empirical evidence or good old ‘gut instinct.’” – The Hindu “[Harari’s] propositions are well-developed, drawing upon a combination of science, philosophy and history. While the book offers a rather pessimistic and even nihilistic view of man’s future, it is written with wit and style and makes compelling reading.” – iNews.
Reviews
"Yuval Noah Harari's "Homo Deus" continues the tradition introduced in his previous book "Sapiens": clever, clear and humorous writing, intelligent analogies and a remarkable sweep through human history, culture, intellect and technology. He starts with exploring the three main causes of human misery through the ages - disease, starvation and war - and talks extensively about how improved technological development, liberal political and cultural institutions and economic freedom have led to very significant declines in each of these maladies. Continuing his theme from "Sapiens", a major part of the discussion is devoted to shared zeitgeists like religion and other forms of belief that, notwithstanding some of their pernicious effects, can unify a remarkably large number of people across the world in striving together for humanity's betterment. As in "Sapiens", Mr. Harari enlivens his discussion with popular analogies from current culture ranging from McDonald's and modern marriage to American politics and pop music. Mr. Harari's basic take is that science and technology combined with a shared sense of morality have created a solid liberal framework around the world that puts individual rights front and center. Ranging from dating to medical diagnosis, from the care of the elderly to household work, entire industries now stand to both benefit and be complemented or even superseded by the march of the machines. For reading more about these aspects, I would recommend books like Nick Bostrom's "Superintelligence", Pedro Domingos's "The Master Algorithm" and John Markoff's "Machines of Loving Grace". As a proficient prognosticator Mr. Harari's crystal ball remains murky, but as a surveyor of past human accomplishments his robust and unique abilities are still impressive and worth admiring."
"And he claims that humanism believes that individuals always know best about their own needs (when in fact, many have emphasized the importance of education in our development--he does not even reference John Dewey). For most of the book, Harari appears to be adopting a materialistic perspective, and one which is also extremely unsentimental and discounts the significance of human morale and character. He also discusses how animals and people have consciousness and subjective experiences, and presumes that artificial intelligence will remain unconscious (the "weak AI" hypothesis of John Searle). And on the very last page, he makes us wonder if his hardcore materialistic perspective has just been a long, extended ruse: he asks us to question a worldview that would deny the significance of consciousness. So it seems likely that in a future book he will focus on the nature of consciousness, and argue for non-theistic Buddhism (an understated agenda in Harari's writing--perhaps he thinks that this is the way for humanity to avoid the grim fate predicted here?). The comment begins with "Harari indeed believes that developing an understanding of consciousness, a science of mind, or however else one wishes to phrase it is the best and perhaps the only way to avert the grim fate that threatens humanity in this century."

This Is Your Brain on Music: The Science of a Human Obsession
• How composers produce some of the most pleasurable effects of listening to music by exploiting the way our brains make sense of the world. • Why we are so emotionally attached to the music we listened to as teenagers, whether it was Fleetwood Mac, U2, or Dr. Dre. • That practice, rather than talent, is the driving force behind musical expertise. • How those insidious little jingles (called earworms) get stuck in our head. Now imagine sitting down with someone who was there when the song was recorded and can tell you how that series of sounds was committed to tape, and who can also explain why that particular combination of rhythms, timbres and pitches has lodged in your memory, making your pulse race and your heart swell every time you hear it. Remarkably, Levitin does all this and more, interrogating the basic nature of hearing and of music making (this is likely the only book whose jacket sports blurbs from both Oliver Sacks and Stevie Wonder), without losing an affectionate appreciation for the songs he's reducing to neural impulses.

A Short History of Nearly Everything (Bryson)
Bill Bryson's challenge is to take subjects that normally bore the pants off most of us, like geology, chemistry and particle physics, and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. His aim is to help people like him, who rejected stale school textbooks and dry explanations, to appreciate how we have used science to understand the smallest particles and the unimaginably vast expanses of space. Though A Short History clocks in at a daunting 500-plus pages and covers the same material as every science book before it, it reads something like a particularly detailed novel (albeit without a plot). What follows is a brick of a volume summarizing moments both great and curious in the history of science, covering already well-trod territory in the fields of cosmology, astronomy, paleontology, geology, chemistry, physics and so on.
Reviews
"This book surprised me in the amount of effort the author took to go through book after book of different sciences, both old and new, and proceeded to connect the dots into several cohesive stories about our home, planet Earth, and its residents."
"I read the hardcover version first, all the while wishing there were pictures, diagrams, maps, etc."
"He is particularly skillful at putting into perspective concepts of size and dimension within the universe, whether mind-bogglingly vast expanses or minuscule marvels of life’s building blocks. Bryson also brings us biographical sketches of the greatest names in science as only an enormously talented humorist could do. Beginning with the unsuspecting and gentle dodo bird, Bryson outlines how we have systematically brought about the termination of thousands of creatures, intentionally or through ignorance."
"Bryson also is quite humorous and ads a lot personal information on various scientists, their inventions and foibles, successes and rivalries."
"Bryson is a talented author who has a tremendous sense of humor (one professional reviewer said that he could make dryer lint seem funny)."

The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory
Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of eleven dimensions, where the fabric of space tears and repairs itself, and all matter—from the smallest quarks to the most gargantuan supernovas—is generated by the vibrations of microscopically tiny loops of energy. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, professor of physics and mathematics at Cornell and Columbia universities, makes the terribly complex theory of strings accessible to all. Just when we might be tempted to dismiss strings as grist for the publish-or-perish mill, Greene explains how they have demonstrated connections between mathematics and physics that have helped solve age-old conundrums in each field. This book will appeal to astronomy as well as math and physics fans because it probes the important insights string theory gives into hotly debated issues in cosmology. Later chapters require careful attention to Greene's explications, but the effort will prepare readers to follow the scientific advances likely to be made in the next millennium through application of string theory.
Reviews
"I'm writing this review before finishing the book since I'm afraid at my pace, by the time I'm done, the theories, and these are theories only, discussed may have changed."
"As with most respected physics-oriented books aimed at non-scientifically-trained readers, you'll learn more about "what is" current theory than you will understand about how physicists got there."
"Brian Greene, professor of physics at Columbia, has written a nice yarn about modern physics (though it is a little dated as I write this), specifically focusing on string theory. As Greene himself admits, string theory has yet to be experimentally validated, but that doesn't stop him. String theory is a candidate (though by no means the only one) for the holy grail of physics, a grand unified theory from which all other aspects of physics can be derived. To build up to string theory, Greene first presents a review of special and general relativity and quantum mechanics."
"Great read, and even fairly easy for someone like me to understand it well enough to enjoy, despite not having any real college-level math or physics beyond Calculus."
"I haven't read too much so far, but I will honestly say I love the history of science in this book and the reflections put forth inside, by different scientists Brian Greene includes to to get to his insights also."
"String theory may by capable of merging quantum mechanics with classical physics, and that simple idea demands respect."
"Il gives an extensive overview of the various theories that have emerged in the last century to describe the motions of the planetes and of the basic particles: from deep space to subatomic scale."

Thinking in Systems: A Primer
In the years following her role as the lead author of the international bestseller, Limits to Growth —the first book to show the consequences of unchecked growth on a finite planet— Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Just before her death, scientist, farmer and leading environmentalist Meadows (1941-2001) completed an updated, 30th anniversary edition of her influential 1972 environmental call to action, Limits to Growth, as well as a draft of this book, in which she explains the methodology-systems analysis-she used in her ground-breaking work, and how it can be implemented for large-scale and individual problem solving. An invaluable companion piece to Limits to Growth, this is also a useful standalone overview of systems-based problem solving, "a simple book about a complex world" graced by the wisdom of a profound thinker committed to "shaping a better future." Just before her death, scientist, farmer and leading environmentalist Meadows (1941-2001) completed an updated, 30th anniversary edition of her influential 1972 environmental call to action, Limits to Growth , as well as a draft of this book, in which she explains the methodology-systems analysis-she used in her ground-breaking work, and how it can be implemented for large-scale and individual problem solving. An invaluable companion piece to Limits to Growth , this is also a useful standalone overview of systems-based problem solving, "a simple book about a complex world" graced by the wisdom of a profound thinker committed to "shaping a better future. This is modestly called a primer, and indeed it is, but unlike most books with that title, this one quickly takes one from the elementary into deep systems thinking about issues as critical today as they were when Dana wrote these words. As the book moves from the 'mechanics' of systems dynamics to Dana's more philosophical perspective, we are treated to her inherent belief in human values that consider the good of all, and how much more effective considering the needs of others is likely to be in solving larger, complex problems. The universe and our society may be very complex and operate in counterintuitive, non-liner fashion, but following the insights of this book and applying them will provide for far more effective solutions to the challenges of a 7 billion person planet than current incremental, linear responses by governments, corporations and individuals." For her systems thinking included the expected things like recognizing patterns, connections, leverage points, feedback loops and also the human qualities of judgment, foresight, and kindness. To live sustainably on our planet, we must learn to understand human-environment interactions as complex systems marked by the impact of human actions, the prominence of nonlinear change, the importance of initial conditions, and the significance of emergent properties. "An inspiring sequel to Dana Meadows' lifetime of seminal contributions to systems thinking, this highly accessible book should be read by everyone concerned with the world's future and how we can make it as good as it possibly can be."
Reviews
"Pros. * Easy, non-jargony language. * Helpful diagrams. * Diverse real-world examples make it relatable. Cons. * Would have liked some exercises to help think through some of the concepts in the diagrams (e.g. feedback flows). * Would have liked some more in-depth case studies where systems thinking was applied, what the challenges were, how cross-functional teams worked together, etc."
"If you can get past the occasional typo this book will leave you with insights that you will use every day of the rest of your life."
"Read the book (your library may have a copy), then write your own review!"
"Reach, interesting material delivered in easy to understand, easy to follow, easy to reference form."
"From lucid introduction to basic stock and flow models to deep meditations on the messiness of reality and the need to extend both attention and caring beyond the limits of the quantifiable, this book is by far the best introduction to system's thinking that I have every read."
"Observe and identify the boundaries and the interconnections between systems before taking decision and judgement."
"A very accessible introduction to Systems, with some great examples and anecdotes."

Einstein: His Life and Universe
Based on newly released personal letters of Einstein, this book explores how an imaginative, impertinent patent clerk—a struggling father in a difficult marriage who couldn’t get a teaching job or a doctorate—became the mind reader of the creator of the cosmos, the locksmith of the mysteries of the atom, and the universe. Isaacson: I've always loved science, and I had a group of great physicists--such as Brian Greene, Lawrence Krauss, and Murray Gell-Mann--who tutored me, helped me learn the physics, and checked various versions of my book. Amazon.com: That Einstein was a clerk in the Swiss Patent Office when he revolutionized our understanding of the physical world has often been treated as ironic or even absurd. Isaacson: I think he was lucky to be at the patent office rather than serving as an acolyte in the academy trying to please senior professors and teach the conventional wisdom. Amazon.com: That time in the patent office makes him sound far more like a practical scientist and tinkerer than the usual image of the wild-haired professor, and more like your previous biographical subject, the multitalented but eminently earthly Benjamin Franklin. Isaacson: There are many creative scientists, most notably Stephen Hawking, who wrote the essay on Einstein as "Person of the Century" when I was editor of Time . In the world of technology, Steve Jobs has the same creative imagination and ability to think differently that distinguished Einstein, and Bill Gates has the same intellectual intensity. I wish I knew politicians who had the creativity and human instincts of Einstein, or for that matter the wise feel for our common values of Benjamin Franklin. That antipathy was symptomatic of Einstein's love of individual and intellectual freedom, beliefs the author revisits as he relates his subject's life and work in the context of world and political events that shaped both, from WWI and II and their aftermath through the Cold War. Isaacson presents Einstein's research—his efforts to understand space and time, resulting in four extraordinary papers in 1905 that introduced the world to special relativity, and his later work on unified field theory—without equations and for the general reader.
Reviews
"Mark F. LaMoure, Boise, ID. "Einstein," is a book by Walter Isaacson who discusses Einstein's life in detail. The book is a fascinating and well-written account by Mr. Isaacson, whose style is to write about people who are so stunning that we need to know what makes them that way."
"The discussion of his thoughts and development of his special theory of relativity and especially of the General Theory show the beauty and creativity of high level science."
"Very long book, but shows that important ideas don't just happen - they require a lot of work and trips down dead ends too."
"Very interesting, previously unknown information, also some good information to understand his theories."
"the Man of E=MC2."
"Excellent biography covering both his scieitific work (at a level understandable to laymen) his personal life (viz a VIs parents, wife's and children) and political beliefs and activism (Judaism, Zionism, racism and work with peers across the globe."
"Good reading for those who are interested in expanding their knowledge."
"A great read, highly recommended."

Reality Is Not What It Seems: The Journey to Quantum Gravity
Do time and space exist? And what exactly is reality? It's a pleasure to read, full of wonderful analogies and imagery and, last but not least, a celebration of the human spirit.” —NPR Cosmos & Culture “If your desire to be awestruck by the universe we inhabit needs refreshing, theoretical physicist Carlo Rovelli…is up to the task.” — Elle. “[ Reality Is Not What It Seems ] is simultaneously aimed at the curious layperson while also useful to the modern scientist… Rovelli lets us nibble or gorge ourselves, depending on our appetites, on several scrumptious equations. “With its warm, enthusiastic language and tone, [ Seven Brief Lessons on Physics ] is also deeply humanistic in approach, using words like elegant and beauty about a subject…that can seem impenetrably dense and abstract… Reality Is Not What It Seems takes much the same approach.” — New York Magazine. “Rovelli’s lyrical language, clarity of thought, and passion for science and its history make the title a pleasure to read (albeit slowly), and his diagrams and footnotes will allow readers to understand the material better and tackle a more expert level of insight.” —Booklist. “Science buffs will admire Rovelli's lucid writing…Cutting-edge theoretical physics for a popular audience that obeys the rules (little math, plenty of drawings), but it's not for the faint of heart.”— Kirkus Reviews.
Reviews
"Rovelli's book is a game changer The title of my review refers to the shining of light in dark places because that's how I felt when I read it. Concepts and theories that I'd struggled with through many of those previous books suddenly made sense."
"Review of: “REALITY IS NOT WHAT IT SEEMS” by Carlo Rovelli. For those who have an even casual interest in modern physics or “science” this is a truly remarkable book. Rovelli is able to take highly complex problems and express them in a way which can make them accessible to even those who think that mathematics is simply something you use to figure out how much change you should get at the supermarket or doing the highly difficult calculation of how much to tip on a restaurant bill. As most readers are aware Einstein’s theories of both general and special relativity are remarkably accurate and have passed every test to which they have been subjected as long as they apply to very large things. Quantum mechanics, the strange physics of the very small, is also exceedingly accurate in its predictions as long as it stays within its “range.” However these two great theories fail miserably when combined. Now, unfortunately, I start thinking; how many half ways are there from the point I have reached to that elusive bathroom? I had until recently mistakenly believed that the concept of space time was an invention of Einstein. The rational for this is highly complex but if this postulate had a bearing on reality could time itself actually be quantized. Thus we have removed from the equations of physics the two things that have always been considered infinite and make them finite. I doubt this will change anything in my life or yours except that I sleep better since I no longer have to worry about not being able to get to the bathroom the next morning."
"Carlo Rovelli continues the tradition from his earlier book, "Seven Brief Lessons on Physics" of combining sparkling descriptions of physical phenomena with a sensitive understanding for the form of physics and the greatness of its practitioners. As in his previous book, Rovelli has elegant descriptions of the two great pillars of physics: quantum mechanics and general relativity. This sets up the book for the second part, which is a theory of quantum gravity called loop quantum gravity. After explaining how quantum mechanics and general relativity disagree with each other in situations where it matters, Rovelli leads us through the main concepts of loop quantum gravity. According to Rovelli, the finiteness of this division enables the theory of loop quantum gravity to escape some of the ugly infinite solutions that results when one tries to combine the mathematics of standard quantum mechanics with that of general relativity. I also find it interesting that string theory which is loop quantum gravity's main rival gets little more than a paragraph, so it's still not clear why one would clearly prefer loop quantum gravity over string theory."
