Scale: The Universal Laws of Life and Death in Organisms, Cities and Companies (English Edition) I had high hopes for this book, because the author is a great researcher and lecturer However this book does not reflect his usual high standard.The beginning is terrible He shows four graphs to illustrate scaling relationships, none of which have intelligible scales I received an advance uncorrected copy, so perhaps some of the issues will be corrected in the final version, but the flaws run deeper than typographic.All the charts have log log scales, although they are labeled in three different formats scientific notation, exponent only or integer There s an old saying that everything looks linear in log log plots The reason that even a very large deviation in ratio of vertical to horizontal variable will look small if the range of the vertical variable is large For example, the graph of number of patents versus population shows ratios that range from about 5 patents per capita to 200 No one would say that illustrates some universal law is in operation But the vertical scale runs from population of 10,000 to 3.2 billion, 4.5 orders of magnitude, and that dwarfs the variation in patents per capita so things look linear Standard statistical tests do not show linearity.Another problem with this chart is there is no explanation of how either variable is defined You can t talk about scale in isolation from what is being measured It s true there is a citation to the original work although not a very helpful one But it turns out that does not support the linearity the author of book claims, the whole point of the chart is to show that larger cities have patents per capita than smaller ones, and says explicitly that the relation is non linear So the chart in the book is not only misleading by construction, it conveys the wrong idea.Another chart shows number of heartbeats per lifetime of animals versus weight It looks constant, because the range seems to be about 30 million to 150 million, but the vertical scale runs from 100 to one trillion Animals turns out to be a few selected mammals whales are listed twice with different values If you go to the paper, the author emphasizes that the interest is in the deviations from the typical relation shown by the animals on the chart the chart only shows the typical animals So far from a universal constant in nature, we find that a subset of mammals happen to have values within a factor of five, with other mammals and non mammals outside that range, but missing from the chart even though the vertical axis is scaled to accommodate them.A better chart shows metabolic rate versus weight here labeled mass despite being the same scale as the previous graph This includes selected mammals and birds, and does illustrate rough linearity in log log space But here the main interest is in the slope of the line rather than the linearity Metabolic rate increases not linearly with mass but at about the 3 4 or perhaps 2 3 power This is key, because a lot of things also go up with powers of mass and people disagree on which ones of them are important for setting the metabolic rate.Finally, there is a chart purporting to show that net income and assets of companies are linear in log log space with number of employees This is clearly nonsense Technology companies often have hundreds of thousands of dollars of net income per employee, and few assets, while retailers have an order of magnitude lower profits per employee but much higher assets There are companies that own and lease things with huge assets and few employees, and service companies that own nothing but a few desks and computers with many employees It turns out if you read the notes at the back of the book that the 22 points are actually averages of over 30,000 companies by the way, page, chapter and figure numbers are wrong in the notes, but I assume this will be corrected before publication So all the chart tells us is when you average over large numbers of companies of different types but similar size, you get similar relations of employees to income and assets as the average for large numbers of companies of a different size.It s not just the charts Also in the first few pages, the author is hyperventilating about the exponential rate of urbanization that has increased the proportion of US residents who live in cities from 4% 200 years ago to 80% today and is an impending tsunami with the potential to overwhelm us A few seconds reflection shows the absurdity of that If the urbanization rate is exponential, and has increased by a factor of 20 in 200 years, then in 15 years we ll be at 100% and the tsunami will stall.Now I know most people think exponential means fast, but most theoretical physicists, and certainly the author, know better It just means that the rate of increase is proportional to the level Nothing in the physical universe is exponential and fast Things can start out exponential, like a fire that spreads faster the larger it grows But that fire eventually uses up available fuel and oxygen and goes out Urbanization in the US since 1790 fits a near perfect Gompertz trend with an asymptote at about 83% that doesn t mean I predict urbanization will stabilize at 83%, drawing curves from the past is a dangerous way to predict the future, but at least a curve that fits the data is better than one that is clearly inconsistent with the data Gompertz trends frequently give reasonable fits to data, exponential curves never do for very long.Another wildly false scare sentence is, It is only relatively recently that we have become conscious of global warming, long term environmental changes, limitations on energy, water, and other resources, health and pollution issues, stability of financial markets, and so on Take those one at a time Global warming started in the mid 1970s, before that the Earth was cooling you could push it back to the 1950s, but the 1950s were cooler than the 1940s note that I m not saying that greenhouse emissions were not affecting the global temperature before 1970, just that the Earth was not warming overall It was not only noticed immediately, before clear statistical evidence of the trend emerged, it had been predicted long before.People have always been aware of limitations on energy, water and other resources, and our supply of resources is far greater than at any time in the past Health People didn t know about sickness and death until recently Pollution The ancient Romans griped and sued about gravioris caeli and infamis aer, and Seneca wrote No sooner had I left behind the oppressive atmosphere of Rome and that reek of smoking cookers which pour out, along with clouds of ashes, all the poisonous fumes they ve accumulated in their interiors whenever they re started up, that I noticed the change in my condition Pollution has been a major political issue in Europe for nearly 1,000 years People have known about instability in financial markets as long as there have been financial markets, and every expansion of markets since has been accompanied by periods of instability and crisis.After all this, only my respect for the author kept me going The book gets quite a bit better when it leaves off the foolishness of the beginning and discusses specific topics with precision and insight Nevertheless, I was overall disappointed by the book It is repetitious and bloated It tries to cover too many topics and relate them all to each other, often in strained ways It mixes solid research with press release studies and outdated speculations The notes are not as helpful as they should be, few of them have any explanation, many are just names of authors or books with no clue about how to find the specific support for the cited claim There is not a clear distinction between patterns that occur for mathematical reasons things like Fibonacci numbers, inverse square laws, Gompertz trends, fractal scaling and power laws versus mathematical patterns that result from top down constraints There is a lot of first rate material as well, but it s not packaged well.Overall, I would recommend this book to people who are well versed in these subjects, with the patience to wade through on overlong and repetitious book for the good parts The author is the undeniable world expert some of these things, and they are very important things to understand Readers who are new to these ideas are likely to be misinformed, although probably entertained Readers who are not patient should look for a better exposition.
