Diet for nerds and computer programmers

John Walker, the founder of Autodesk, has written an interesting guide on health and weight loss, which is available for free online: The Hacker’s Diet.

Basically, the book focuses on the fundamental mathematical issues associated with weight loss and gain, and describes some useful techniques for transitioning to a lower weight. In particular, the moving average approach to measurement described seems quite valuable, insofar as it helps to separate the ‘signal’ of actual weight from the ‘noise’ of variation in things like water retention. The moving average generates a trend line that seems like it should provide more meaningful guidance than a scatterplot of individual data points, or even a simple curve fit to them.

The book also describes a 15-minute health regimen that ramps up in difficulty and is intended to serve as a minimum level of exercise for life.

The book is quite an unusual one, as health books go. For instance, it endorses frozen microwave dinners as a convenient way to get a predetermined number of calories. It also insists that exercise is not a critical weight loss strategy, and that some degree of suffering inevitably accompanies efforts to move closer to one’s ideal healthy weight. While I am sure people could take exception to this approach, it is good to have variety out there, and encouraging that tools are being created for the ever-larger number of people worldwide that are overweight or obese, and likely to suffer significant health risks as a consequence.

Sustainable Energy – Without the Hot Air

David MacKay’s Sustainable Energy – Without the Hot Air is a remarkably engaging book; it has certainly kicked off and contributed to some very energetic discussions here. The book, which was written by a physics professor at Cambridge and is available for free online, is essentially a detailed numerical consideration of renewable forms of power generation, as well as technologies to support it, and to reduce total power demand. MacKay concludes that the effort required to produce sustainable energy systems is enormous, and that one of the most viable options is to build huge solar facilities in the world’s deserts, and use that to provide an acceptable amount of energy to everyone.

The book has a physics and engineering perspective, rather than one focused on politics or business. MacKay considers the limits of what is physically possible, given the character of the world and the physical laws that govern it. Given that he does not take economics into consideration much, his conclusions demonstrate the high water mark of what is possible, with unlimited funds. In the real world, renewable deployment will be even more challenging than it is in his physics-only model.

Here are some of the posts in which the book has already been discussed:

I have added relevant information from the book to the comment sections of a great many other posts, on everything from wind power to biofuels.

Even if you don’t agree with MacKay’s analysis, reading his book will provide some useful figures, graphs, and equations, as well as prompt a lot of thought. It is certainly one of the books that I would recommend most forcefully to policy makers, analysts, politicians, and those interested in deepening their understanding of what a sustainable energy future would involve.

Getting Green Done

Auden Schendler’s Getting Green Done: Hard Truths from the Front Lines of the Sustainability Revolution fills an important niche in the overall discussion about climate change and building a low-carbon global society. As the director of sustainability for the Aspen Skiing Company, he has personal experience with pitching and sometimes executing green projects, including those involving efficient buildings and renewable energy. His book offers some valuable on-the-ground observations that are lacking in higher level discussions like that of David Mackay. While the detail is welcome, the book does sometimes lack a sense of the bigger picture. The language and tone can also be annoyingly jocular, at times.

The most useful information in the book concerns the hurdles that exist to getting green projects done, even when they are well justified on the basis of lifecycle cost analysis. The initial investment is always larger, both in terms of time and complexity, and there are real risks associated with deviating from normal practice. Policymakers could clearly benefit from more direct discussion with the people who are ‘closest to the action’ and actually responding to policies when making their choices. In the end, Schendler sees a huge role for government: putting minimum standards into codes, providing financing to get projects going, and restricting the ways in which corporations can act while pursuing profits.

Schendler also weighs in on the value of individual actions, highlighting how only societal changes have the capacity to overcome climate change. Even so, personal actions are important for establishing credibility, which translates into some of the influence required to drive bigger changes. As a practical discussion of successes and failures, rather than a higher level theoretical work, this book is worth the time of those concerned with dealing with climate change.

Collapse: How Societies Choose to Fail or Succeed

In marked contrast to his previous book, I found Jared Diamond’s Collapse: How Societies Choose to Fail or Succeed to be a consistently compelling and worthwhile read. He begins and ends it with discussions of environmental challenges in the modern world – firstly, in Montana and secondly globally – and fills out the book with descriptions of past societies that failed for primarily environmental reasons. These include Easter Island, Pitcairn and Henderson Islands, the Anasazi of North America, the Maya, and the Vikings of Greenland. He sketches out a ‘five factor’ framework for evaluating how both internally and externally induced environmental changes affect societies: environmental damage, climate change, hostile neighbours, friendly trade partners, and how a society chooses to respond to its environmental problems. Diamond makes a strong case that the framework is relevant to contemporary global society.

Diamond makes some good points about psychology. For instance, about how people who become used to abundance can forget that they are benefitting from a temporary blip above the trend line, and can end up getting hammered when things return to normal. Also, how the construction of status symbols can develop a momentum of its own, and carry on well beyond the point where it would be objectively sensible to continue. He also describes some of the many perverse subsidies that have been established by well-meaning rulers, such as the former obligation of Australian landowners to clear native vegetation, ensuring the worsening of their erosion problems.

While Diamond concludes that twelve different environmental problems are of sufficient importance to threaten the future of our society, he doesn’t perform much comparative analysis on their relative urgency and severity. Indeed, a case could be made that he seriously underestimates climate change, when compared to the others. Not only is the need to start mitigating urgent, due to long lags in the climate system, but the impacts of further emissions are irreversible to an extent that is not shared by all the other problems he lists.

While Diamond does an excellent job of chronicling reasons for historical societal failures – and argues convincingly that an appreciation of this history is important for understanding our current situation – he doesn’t do much of the work of considering what societal changes are necessary now. In particular, his assertion that a deep change in values may be required doesn’t extend to listing which of our values are problematic, or what changes to them might help society overcome the problems he anticipates will threaten it in coming decades.

Diamond’s final position is a very forceful one: for a constellation of reasons, our present global society is deeply unsustainable, and much of economic ‘growth’ is illusory. We are ‘mining’ renewable resources, in a way that will destroy them in the long term. As such, we are not earning a living off the ‘interest’ accrued to natural capital – we are cutting into the capital itself, dooming future generations to a worsened standard of living, or worse, unless we change our ways. That, plus the lesson that successful past societies were undone by failures to heed such lessons, is information that needs to be more widely absorbed and appreciated within our society.

Marriages and alliances

In Frank Herbert’s Dune, the character Lady Jessica is under orders from a powerful group to only bear her husband daughters. Eventually, it is revealed that the purpose of this was to ensure that her daughter could be wed to the son of an enemy clan, in order to seal the rift between them.

While such marriages have a medieval feel, it certainly seems to be the case that such unions can unite differing factions and promote the emergence of new political unions. It will be interesting to see how gay marriage changes that dynamic, especially if it spreads beyond liberal democracies. Such unions will not be able to produce biological children – for the foreseeable future – but perhaps they will still serve the role of binding groups together.

How different Dune would have been if Paul Atreides could have wed Feyd-Rautha or Glossu Rabban.

Why Your World Is About to Get a Whole Lot Smaller

Jeff Rubin is a Toronto-based economist for CIBC World Markets, and he has written a book predicting a future of “triple digit” oil, and some of the consequences it will have. While the book is interesting and many aspects of the hypothesis are plausible, the lack of rigour in analysis makes the work less convincing than it might otherwise have been. For one thing, “triple digit” oil covers an awfully broad range. For another, it isn’t clear whether the effects he predicts will unfold in the order he anticipates. For instance, if severe climate change impacts emerge before acute and permanent increases in the price of fossil fuels, the global consequences may look rather different.

When he says that the world is going to get ‘smaller,’ Rubin is reversing the normal sense of globalization having shrunk the world. What he really means is that the world will get larger, relative to our ability to travel and move goods, and that we will have a correspondingly more local focus as a result. That means less imports of all kinds, less travel, and the re-localization of industry. Rubin’s strongest points and arguments relate to the production and use of fossil fuels: such as the effect of domestically subsidized fuels in oil producing states, the limitations associated with energy efficiency, the problems with corn ethanol, and the importance of energy return on investment, when contemplating alternative fuels and sources of energy.

Rubin’s habit of mixing established fact with speculation, and sometimes dismissing important possibilities with a brief splash of rhetoric, makes this book more valuable as a prod to thinking than as a guide to what is likely to happen. The book also contains the occasional overt error, such as referring to prosperous South Korea as the ‘Hermit Kingdom’ – rather than the tyrannical regime to the north. The chapter on climate change was certainly lacking in ways that make me doubt the overall quality of Rubin’s understanding and analysis. He doesn’t really seem to grasp the concept of a stabilization pathway, technological wedges, or the physical realities that must accompany the stabilization of greenhouse gasses at a safe level. His discussion of electrical generation – in both fossil fuel based and alternative forms – is similarly lacking in detailed and rigorous evaluation.

In the end, Rubin’s work is an interesting way to set yourself thinking about the effect that constrained energy ability would have upon the world and your life. When it comes to evaluating the macroeconomic and societal consequences of such a development, the book would probably best be read alongside a more transparent and quantitative analysis, such as that in David MacKay’s book on sustainable energy.

Insultingly Stupid Movie Physics

Tom Roger’s Insultingly Stupid Movie Physics teaches basic science principles in one of the most entertaining ways possible: by illustrating the ways in which elements of popular Hollywood films are hopelessly out of line with the physical laws that exist in our universe. Topics covered include the laws of motion, gravitation, vehicles, the behaviour of weapons, relativity, extreme weather, space travel, and more.

While the book may seem whimsical, Rogers makes the important point that movies are a form of vicarious experience for people. For most of us, they have provided most of our ‘knowledge’ about firearms, knives, the extreme operation and destruction of vehicles, the destruction of buildings, etc. By consistently misrepresenting these things, films leave people ill-equipped to understand the phenomena in the real world.

In addition to this, Rogers’ book includes a detailed debunking of two conspiracy theories partially fuelled by a poor understanding of physics. In the first, he discusses the physics of the JFK assassination, in the context of the popular film. He argues that the official account is convincing for a number of reasons, and that the film has helped to entrench a serious misunderstanding in the minds of many Americans. The second conspiracy theory – that the World Trade Centre was destroyed using explosives planted inside – is similarly based in a bad understanding of physics, and similarly damaging in terms of the way in which it colours people’s thinking.

The kind of people who take delight in outsmarting the people who make movies will probably find this book very entertaining. Those trying to teach physics concepts may also find it useful as a mechanism for engaging people and having them explore ideas in an imaginative but realistic way.

The Bridge at the Edge of the World

The basic contention of James Gustave Speth’s The Bridge at the Edge of the World: Capitalism, the Environment, and Crossing from Crisis to Sustainability is that dealing with climate change – and environmental crises more generally – requires a major project of societal reform. This includes rejecting economic growth as a major objective, and focusing instead on improving the non-material factors that determine happiness. It also involves major economic and political reforms: severely curtailing the autonomy of corporations and sharply altering the relationships between business and government. While Speth’s vision is a coherent one, I don’t think he makes the case convincingly that it is the only alternative to ecological collapse. Indeed, implementing elements of his broader social program may well involve political battles that delay effective action on climate change.

One basic idea that Speth expresses well is a two-phased understanding of human civilization. In the first stage, exponential growth occurs and the proper mentality is that of the frontier or entrepreneurship. The second phase, basically the death of libertarianism, is when population and ecological strain become so significant that society and world level planning become necessary. It is clear that we are moving from the first to the second, as a civilization, though it remains unclear whether we will be able to manage that transition well, and avoid most of the damage and suffering that would result from getting it wrong.

Speth’s chapters on government and corporations seem like they were taken directly from AdBusters or Naomi Klein. That is not to say their analysis is wholly incorrect, but I do think it seriously overstates the power of corporations. Ultimately, they are subject to the will of governments. Of course, they have a strong ability to influence governments: both directly and by manipulating voters. Nonetheless, the authority and capability necessary to solve the world’s most pressing environmental problems lies with governments, and the process of achieving that will be all about altering their internal thinking and incentives. Speth’s analysis is also almost entirely focused on political and economic reform, in the sense of corporate governance. He pays relatively little attention to technological development and deployment, or to the economic instruments through which both can be advanced.

Speth is clearly well-read on the subject of the environmental movement. Indeed, his book is so riddled with quotations that his own voice and perspective are sometimes obscured. It isn’t always clear whether he is wholeheartedly endorsing someone’s idea, or introducing it as a partial contrast to his own point. Despite that, Speth’s writing is concise, clear, and often compelling. While readers may not find themselves in total agreement at all points, Speth at least provides some solid concepts and arguments to respond to.

Ultimately, the approach described in The Bridge at the Edge of the World comes across as somewhat unfocused. The author presents a package of reforms as through each is integral to all the others, but doesn’t make a strong enough case for why that is so. Indeed, the book also fails to present a coherent path from the present forward into a reformed world, indicating which elements are better primed to emerge soon. It may be sensible to argue for more progressive taxation, banning advertising to children, supporting sports and hobbies, providing free child care, etc, but some of these things are clearly secondary to the process of reconciling human civilization with the physical and biological limits of the planet.

Indeed, a strong case can be made that climate change will only be truly solved when it becomes post-ideological: when all the major political ideologies in states with serious greenhouse gas emissions come to accept the fact that they must be reduced and ultimately eliminated. Without that consensus, it seems unreasonable to expect the process of mitigation to continue for decade after decade. By tying the need to mitigate into an overly specific political framework, Speth puts forward a proposal that could obstruct that process, or lead to it sputtering out with the political ascendacy of a group with different perspectives and priorities.

Changing Images of Man

First published in 1974, and available for free online, Changing Images of Man is a kind of philosophical reflection on science and how human beings understand themselves. While it does touch on some interesting ideas, the degree to which it is fundamentally lacking in rigour or discipline means that it is also choked with nonsense, impenetrable jargon, and pointless speculation. In short, it does not have the feel of a text whose ideas have been borne out by subsequent history. Rather, it is more like a monument to a kind of faddishness that has long since become dated, though elements endure in the more superstitious aspects of contemporary culture.

Much of the book concerns environmental issues: specifically, how human civilization can cease to be such a destructive force, and how ecology is affecting science in general. Neither discussion is very satisfying. The former discussion focuses on a kind of caricatured extension of the Beatles going to India to lean yoga and discover themselves. While significant transformations in human behaviours and self-understanding may well be necessary to generate a sustainable society, the perspective on those changes offered in this work doesn’t seem either plausible or compelling to me. The latter discussion exaggerates the degree to which the study of complex dynamic systems challenges the practice of science: while they are certainly more challenging to study scientifically than systems that are more easily broken down and understood in terms of constituents, science is nonetheless proving increasingly capable of dealing with complex systems like climate and ecosystems, and is doing so without the kind of radical extension and modification endorsed by this book.

Much of the book is no more comprehensible than a random string of pompous-sounding words strung together in a grammatical way. It seems telling that the chapter on ‘feasibility’ is the least accessible and comprehensible of the lot. The report perceives a crisis in science that I don’t think existed at the time it was written, and I do not think has emerged since. Complex phenomenon are being grappled with using enhanced versions of conventional techniques, while UFOs and psychic phenomena have been effectively rejected as quackery, due to the absence of any good evidence for their existence. Basically, Changing Images of Man is an exhortation to abandon rigorous thought in favour of a kind of wooly inclusiveness, exceedingly open to ideas that are too vague to really engage with. The book has a naive counterculture tone, overly willing to reject what is old and unthinkingly embrace novel concepts that register with a 1960s/1970s mindset. While the questions it considers are generally good and important ones, the answers provided are vague, preachy, and largely useless.

The White Man’s Burden

William Easterly’s The White Man’s Burden: Why the West’s Efforts to Aid the Rest Have Done So Much Ill and So Little Good seeks to refute utopian notions of what can be done with foreign aid and military interventions by citing evidence from past disasters. In his analysis, the planners who develop and implement foreign aid plans lack the capability, incentive, and ability to provide what is really needed by the poor. Rather than continuing to empower them in seeking grand solutions, mechanisms should be established through which ‘searchers’ can create meaningful initiatives to deal with specific, tractable issues. One paragraph sums up the basics of Easterly’s view of development:

Even when the West fails to “develop” the Rest, the Rest develops itself. The great bulk of development success in the Rest comes from self-reliant, exploratory efforts, and the borrowing of ideas, institutions, and technology from the West when it suits the Rest to do so.

He argues that Western states should abandon their pretences and most of the approaches they have deployed so far. Because of the fundamental linkages of accountability they create, Easterly holds that markets, rather than bureaucracies, are the ideal mechanism for serving human needs. He does not, however, have an excessive faith in the ability of effective markets to emerge: stressing that they can do so only when social, legal, and political conditions are appropriate. Given that the complexities of these things aren’t even understood in relation to long-standing markets in developed states, he argues that it is unrealistic to try to develop and deploy market creation plans in poor states.

One somewhat curious aspect of the book is a focus on countries which is sometimes too rigid, with less consideration of the economic breakdown within them. Almost always, the most authoritative measure of a country’s success is taken to be the level of GDP and the rate of GDP growth. Comparatively little consideration is given to the distribution of wealth or income. Claims made about different forms of poverty reduction could have been more comprehensively examined through a combination of aggregate data and considerations of distributions.

Easterly acknowledges that health is an area where aid has done unusually well – partly because health problems lend themselves to the kind of high-accountability, distributed solutions he favours. Efforts to eradicate certain diseases with vaccines and medication demonstrate that big, expensive efforts are sometimes justified. Recognizing that, the book is highly critical of health efforts that fail to take into account local conditions. It is also very critical of spending money on AIDS treatment. Easterly argues that such treatment costs about $1,500 a year, in total, with only a few hundred of those dollars for the generic first-line drugs themselves. Since both preventing the transmission of AIDS and treating other diseases can extend the total number of years of human life much more efficiently, he argues that funding AIDS treatment is a gross misallocation of resources. He also argues that it is important to counteract entities that are doing enormous amounts of harm: such as the Christian organizations that push governments and NGOs to back away from condoms, or those that promote useless abstinence education programs. Other education programs can be enormously more effective: such as teaching prostitutes about AIDS and how to prevent it with barriers.

The book completely ignores environmental issues, which I see as a major problem. Climate change is a huge threat to development, and carries many risks of poverty and conflict. Easterly rightly criticizes planners everywhere from failing to anticipate the eventual consequences of the AIDS epidemic, and taking preventative action beforehand. Inadequate global action on climate change threatens to produce a much worse problem. When the book praises Beijing for having eight beltways around its core, it highlights the difference I have seen in other places between pro-growth development economists and others who are more concerned about the environmental consequences of such unbridled activity. While environmentalists are often insufficiently concerned with poverty reduction (sometimes monstrously suggesting that keeping most people in poverty is a good way to lighten the environmental burden), economists are often guilty of ignoring the real impacts and enormous threats associated with being unconcerned with sustainability.

Easterly’s suggests that organizations that provide or distribute aid need to be much more focused on particular, comprehensible tasks and that mechanisms must be in place to evaluate their effectiveness at serving the interests of the people who are the targets of the aid. They should concentrate on providing basic needs in a direct way: things like medicine, seeds, roads, textbooks, and medical staff. Results should be evaluated using scientific approaches (both randomized trials and statistical analyses) conducted by truly independent organizations. The concept of ‘development vouchers’ which could be given to poor people and then used in exchange for development services, from an organization selected by the recipients, is an example of the same general kind of thinking.

The book’s style deserves some criticism. It is written in the form of dozens of little sections, each a few pages long. It can also be rather repetitive. Sometimes, Easterly’s points of rebuttal are glib or unconvincing, delivered in an offhand way without a great deal of logical or empirical justification. That being said, his overall conclusions are well supported by a great deal of statistical, historical, and anecdotal evidence.

In the end, the book is one that ought to be read by all those with a serious interest in international development, and the relations between the developed and developing world. While it is not universally convincing, it is a useful contribution to the overall dialogue and a sensible rebuttal to the excessive idealism (even utopianism) or some plans and political positions. The book is also interesting insofar as it considers what elements produce stable and prosperous societies, and which characteristics lead to misery and stagnation. Those are lessons that can be sensibly applied even within the states which already consider themselves to be fully developed.
