I liked this very much. The main thesis is that science up to fairly recently has been Platonic (which this book instead, and I think mistakenly, characterises as reductionist) and therefore fixated on describing things and their forms. This idea is that if you have a picture you want to study you will learn all that there is to learn about it by pulling all of the jigsaw pieces apart and studying these individual pieces in detail. As String Theory shows, we can always speculate on smaller and s ...more

One of those anti-reductionist, complexity-obsessed, nonsensical collections of persuasive anecdotes and loose (useless) analogies.

The main critique of reductionism is that it not always useful.
Some problems can't be easily solved from 1st principles.
The author points out the solution would be a departure from reductionism.

But this straw-man strict reductionist doesn't exist in the first place.
Rocket scientists don't model engines on the quark-scale!

Supremely interesting book that delves into network theory and how it's understanding and growth in every branch of science from Biology to Computer Science and Economics will undoubtedly change the way we view the world. It is very exciting to be alive during this time in which the underlying mathematical laws that govern networks are being revealed. Being a student of complexity ever since I read Nassim Nicholas Taleb's book "Antifragile: Things that Gain from Disorder" and followed it up with ...more

O tipo de livro que coloco ao lado do The Information: A History, a Theory, a Flood do James Gleick na categoria "livros que fazem sua visão de mundo mudar". Recomendo o Linked para qualquer pessoa que trabalhe com ciência ou com relacionamentos humanos ou entre qualquer variável. A noção de como redes são construídas e funcionam, de sites a pessoas, ou mesmo proteínas, e como as propriedades que explicam este tema são relevantes para tudo que fazemos.

This is great stuff. A very sexy topic as far as physics is concerned. And while that may be just a cliche description that I'm fond of using- sex is actually a relevant topic in the field of networks. Did you know that a sexual network has the same topological structure as the world wide web? Well it does! Prostitutes are like google and your personal website is probably like a virgin. Anywho, while the content is extremely interesting, if you have any prior knowledge of networks, you might fin ...more

A very well-written exposition of network theory for a general audience, with extensive end-notes where the author has hidden some of the math. It deals not only with the ideas of networks but also the mathematicians and scientists who study them, resulting in some appealing anecdotes. Beginning with Euler and his 7 bridges of Königsberg problem which gave birth to graph theory, Barabási follows the development of ideas about the nature of social relation nets, the structure of the internet, as ...more

This was incredible. I want to pursue this field full time, professionally after reading this book.
I would like to see an updated edition of this book come out soon, one that includes the latest research in protein, gene, and microbiome networks.

In the first few chapters, the author guides the reader through the early decades of research in complexity. When networks were first realized, their connections were thought to be random. However, power laws were discovered to be involved in the emergence of every self organizing system. This was a thrilling insight that has held up in subsequent fin

A good non-fiction book for people who would like to be introduced to network science without learning rigorous mathematical formulae. Also, this book can be useful for network science researchers in order to formulate their scientific ideas about network science in laymen terms.

This is an excellent read. It isn't filled with much technical speak and is written in a very easy to read manner. The flow of the book is also very good.

I found this book far more enjoyable than 'Sync' which I found hard to follow at times, even though both books deal with similiar subject material. Barabasi has created something here that anyone can read and understand.

In summary the book looks at network theory and the discoveries that have been made recently that change the manner in which w

This is an excellent introduction to the world of social network analysis. Very easily written for an introductory audience and introduces all the essential concepts, yet an excellent treatise on the more intricate and state of the art issues around social network analysis. It's always a pleasure to read firsthand accounts from the authors of the power-law distribution in social networks, the issues around growth models, and preferential attachments.

This took me a long time to finish. It was hard to stay interested, especially when they were talking about the internet. Even though the book isn't that old, it felt quite dated. I get that the early days of the internet were exciting in figuring out how the networks worked, but they kept sounding really surprised that some web pages have more links to them than others, a fact to which any person NOT entrenched in the network theory mindset would have said, "yeah, well, duh."

This book has a lot of interesting information about the structure of the Internet. Unfortunately, it was poorly written. It reiterates simple points and fails to spend enough time explaining the complex points. The author seemed to have in mind certain phrases that had to appear in the book and includes these and strange metaphors in places where they don't fit. It also goes off on too many tangents about the publication process of university professors. I listened to the book on CDROM, and it ...more

This is a very interesting and extremely in-depth look into the science of networks - anything from 'who actors have worked with,' to 'computer networks,' to good ol' real life 'analog' social networks (i.e. 'who you know, and who they know'). Basically, anything with nodes connecting to other things. This book looks at the science of networks primarily from a 'mathematical model' perspective, and as such it was frequently beyond my comprehension. Indeed, though this book was engaging and covere ...more

Interesting enough, though repetative. A pop-cultural textbook for very complicated mathematics/statistics, but never-the-less very relevant and very interesting. The first half of the book builds the groundwork for the information explained in the second half, though for the most part the book just repeats the same concepts over and over (maybe needed for something so compicated).

To be honest I already had intuitively come to some of the same conclusions these mathemeticians and physicists came

An engaging, well-written, highly accessible account of the theory behind networks, and the growing importance of this theory in the modern world.

Barabasi could serve as a role model for all aspiring science writers - this fascinating book takes a difficult subject and renders it accessible to non-expert readers. To quote 'The Boston Globe':

" Linked should be mandatory reading for academics as a primer in good writing. Barabasi may be a scientist, but he didn't neglect his liberal arts educati

Simple, but amazing books that make the holistic, universal aspects of networks and their principles accessible to everybody.

This is a great introduction to network science. Barabasi provides an overview of the fundamentals of network science, covering random network theory, scale-free networks and the role of hubs. He combines this with detailed illustrations of various phenomena, such as the spread of Christianity, the propagation of cancer in cells and the spread of computer viruses. I highly recommend this for anyone any remote interest in

Similar to "The Tipping Point" -- it's more academic and uses examples beyond social settings, and takes some of the same ideas further in more depth. Not quite as accessible as The Tipping Point, but also more realistic and less 'romanticizing' of the science.

Linked is written in an engaging way, and the ideas are all simplified well for laypeople. I particularly liked that it was structured in the same way as the networks it describes -- this is smart, and subtle (though maybe lost on a good chunk of its audience). I would definitely recommend it for someone who has little to no experience working with or understanding complex networks. People in business in particular could probably get something out of it. However, the most glaring feature of this ...more

This book wasn't what I expected, which meant I had to readjust my mindset going in. I had the impression it was about how disciplines and events are interlinked (more cause-and-effect), but is actually about the mathematics of modeling networks. Which turned out to be really interesting, if a little dry. I appreciated the history, and the gradual building up of our current understanding of networks; it seemed slow, but since I have no background in the subject, it was a good pace.

An interesting introduction to the science of networks. It does however disappoint on a couple of levels.

First it builds the basic foundation of how networks are structured (nodes with links, power laws, scale-free models) in brief segments with clear explanations from a number of specific examples such as the internet or the network of scientific academics. It feels like the detail peters out half way through however. The remainder of the book is a sequence of fairly brief descriptions of how t

4.5 stars. This book is a delight for anyone interested in the far reaching applications of graph theory and the revolution it has brought about in studying existing problems in intriguing new ways.

I was a little surprised to note that apart from the theory, which I was mostly aware of, my key takeaways seemed to be the applications of networks in biology. For example, in one exceptionally interesting chapter, the author discusses research on how the scale-free nature of protein networks inside

A gentle introduction to the concept of networks and related topics in graph theory and statistics. Very light on math (most formulas are relegated to footnotes), heavy on examples from a wide variety of fields, interesting trivia and wit. Barabási starts the book with a simple network model and gradually introduces enhancements to it, showing the adventages and limitations of each intermediary step. This book is a joy to read and it can help you get in the proper mindset to "grok" networks; how ...more

“In retrospect, Euler's unintended message is very simple: Graphs or networks have properties, hidden in their construction, that limit or enhance our ability to do things with them. For more than two centuries the layout of Konigsberg's graph limited its citizens' ability to solve their coffeehouse problem. But a change in the layout, the addition of only one extra link, suddenly removed this constraint.” 2 likes
