Innovation and Its Enemies.

The late Calestous Juma died shortly after the publication of his last book, Innovation and Its Enemies: Why People Resist New Technologies, which may be why the book is still so little-known despite its obvious relevance to our fast-changing, tech-driven economy. Juma was a professor at Harvard’s Kennedy School with a longtime focus on international development, especially the application of new technology to developing countries and to boosting sustainable development. While the prose is a bit on the academic side, Juma uses very well-known technologies and even other inventions that you might not think of as ‘technologies’ but that still drove massive cultural and economic changes that led to substantial societal, religious, or political opposition.

Juma’s main thesis is that there will always be forces that oppose any new technology or invention that offers the potential for change, and he tries to categorize the reasons for and the types of opposition that any innovation might face. Some of the case studies he covers are ones you’d expect, like the printing press, refrigeration, and genetically modified crops, but he also covers less-expected ones like margarine and coffee. Margarine was invented in the mid-1800s and faced a torrent of opposition from dairy farmers, leading to the development of dairy associations that lobbied Congress and state legislatures for absurd laws that restrained or prohibited trade in butter alternatives, from requiring labeling designed to scare consumers to requiring the stuff to be dyed pink to make it less appetizing. To this day there are still regulations that overtly favor dairy butter that date from decades ago, although the discovery that the trans fats in traditional margarine are deleterious to heart health has made such laws anachronisms.

Coffee might be the most fascinating story in the book because it appeared and spread like a new technology, even though we don’t think of it as one. Coffee originated in east Africa, notably Ethiopia, and spread across the Red Sea to Yemen, from which it began to permeate Arab societies and faced its first wave of opposition from Muslim authorities who feared its stimulant effects (with some imams ruling it haram) and from secular authorities who feared the culture of coffeehouse would give rise to organized political groups. The same two forces applied when the drink spread to Europe, where it also faced a new group campaigning against its spread: producers of beer and wine, who feared the drink would replace theirs – in part because all three were safer than drinking well water at the time – and employed every trick they could find, including getting “doctors” (such as there were in the pre-science era) to claim that coffee was harmful to one’s health. While there are still some religious proscriptions on coffee, the drink’s spread was eventually helped by its own popularity and by the split among many authorities on its beneficence and value, with monarchs and even the Pope coming out in favor of the drink.

The two chapters that look at the ongoing controversy, most or all of it fabricated, over transgenic crops is probably the most directly relevant to our current political discourse, as genetically modified organisms are probably required if we’re going to feed the planet. Juma shows how GMOs suffered because regulatory authorities were consistently behind the technology and had to react to changes after they happened, and then often did so without sufficient guidance from technology experts. No example is more appalling than that of a genetically modified salmon called the AquAdvantage salmon that grows to maturity in about half the time required for wild salmon, and that thus has the potential to reduce overfishing while providing a reliable protein source that also has less impact on the environment than protein from mammals or poultry. The U.S. government was totally unprepared for the arrival of a genetically modified animal designed for human consumption, which also gave opponents, from Alaskan legislators (including Don Young, who openly promised to kill the company behind AquAdvantage) to fearmongering anti-GM advocates (look at the “Concerns” section on the Wikipedia entry for the fish), time to maneuver around it, blocking it through legislation and excessive regulatory obstacles.

Where Innovation and Its Enemies could have used more help was in how Juma organizes his conclusions. There are common themes across all of his examples, from the natural human fear (especially those of adults over age 30) of change to concerns over job loss to questions about environmental impact, but the choice to organize the book’s narrative around specific case studies means that the conclusions are dispersed throughout the book, and he doesn’t write enough to bring them together. A book like this one could be extremely valuable for policymakers looking to create an environment that encourages innovation and facilitates adoption of new technologies while providing sufficient regulatory structure to protect the public interest and foster trust. It has all of the information such a reader would need, but it’s scattered enough that a stronger concluding chapter would have gone a long way.

The Warmth of Other Suns.

Isabel Wilkerson says she spent 15 years researching the book The Warmth of Other Suns: The Epic Story of America’s Great Migration, which won the National Book Critics Circle Award for General Nonfiction in 2010, and the research shows in the incredible depth of detail in this tripartite narrative about the mass movement of black Americans from the Jim Crow South to the north and west from 1915 to 1970. Wilkerson, who won a Pulitzer Prize for journalism while working for the New York Times, interviewed over 1200 people, and focused this sweeping saga on three African-Americans who fled the south’s limited opportunities and overt, violent racism, fleeing Mississippi, Florida, and Louisiana for Chicago, New York, and Los Angeles. Their stories are interwoven with each other’s and with other related histories of others who followed similar paths, and the tragedies of some of those who chose to stay behind.

Wilkerson gives us three characters who will accompany us through the book’s 600-odd pages (for me, 22-plus hours of audio): Ida Mae Gladney, a sharecropper’s wife from Mississippi who followed her husband, George, to Milwaukee and eventually the south side of Chicago; George Starling, a fruit picker from Eustis, Florida, who tried to organize other fruit pickers to earn better wages but fled from white landowners who set out to lynch him; and Robert Pershing Foster, a doctor from Louisiana who became a successful surgeon in Los Angeles and served many celebrity patients. The three all marry and raise children, and all find greater prosperity in the north than would ever have been possible where they were born, but all face the normal travails of any working-class life, and each carries some of the baggage of their birth and upbringing as outcasts in a racist country well into adulthood.

All three have compelling, often heartbreaking individual stories – although I think Wilkerson’s touch here is so deft that she could make anyone’s life story compelling – but none was more fascinating than the path taken by Dr. Foster, who left Monroe, Louisiana, and found success as a doctor in California both by outworking other doctors and by bringing an intense, precise sort of personal attention to his patients. Shedding his childhood name of Pershing after he moved to go by the more conventional name of Robert, Dr. Foster seems to have achieved the American dream against long odds, earning material wealth, marrying well, raising three daughters who themselves became successful, thus creating an ongoing chain of success and upward mobility from his own struggle. Yet he never seems to be able to escape the scars of a childhood (and possibly a marriage that brought him in-laws who never thought he was good enough) in a way that allows him to enjoy his success. Wilkerson illustrates him as a demanding, controlling husband who was meticulous about his own appearance and that of his wife, while he also was a compulsive gambler who clearly enjoyed how his spending at casinos bought him a form of respect at the casinos he frequented. Later in the book, Wilkerson tells of a gala Foster threw in his own honor, and how he agonized over every detail of the party, and how he couldn´t enjoy it during or afterwards because of perceived imperfections in the result.

At times a brutal, unsparing look at the treatment southern whites doled out to the black underclass as a matter of course, The Warmth of Other Suns is also deeply personal and empathetic. Wilkerson tells several stories of lynchings, including Leander Shaw and Claude Neal, the latter of whom was brutally tortured before he was hanged for a murder he may not have committed. She details the violent, racist reign of Lake County, Florida, Sheriff Willis McCall, accused at least 50 times of abusing or killing black suspects in his custody, once shooting two handcuffed black prisoners in cold blood and finally ousted from office after eight terms when he kicked a black prisoner to death. (McCall’s son, now 64, was arrested in January for molesting a young girl and possessing child pornography. He had stated in the past that his father was innocent of all charges of civil rights violations.) George Starling leaves Florida because a friend tells him local whites are going to take him to a swamp for a ´necktie party,´ racist slang for lynching. Ida Mae and her husband, also George, leave their life as sharecroppers under a benevolent but still manipulative, controlling landowner after a friend of theirs is beaten into senselessness over the theft of some turkeys that, it turns out, had just wandered off. Robert Foster isn’t driven out the same way but realizes that as a black doctor who can’t even receive admitting privileges at the white hospital, he’ll end up as just a ‘country doctor’ if he doesn’t move out of the land of Jim Crow.

The stories of violence and outright suppression are hard enough to fathom today, but the smaller indignities that the three protagonists and other African-American characters in the book faced fill in the gap and have even more impact because they’re easier to ingest today, when lynchings like that of James Byrd Jr. are extremely rare and result in actual convictions of the killers. When Dr. Foster is driving to California and can’t find a hotel room, even though some white proprietors are kind in rejecting him, lying to his face about vacancies, you can see and feel it. When Ida Mae has to take a series of temporary jobs in Chicago, where most employers will still choose only white candidates, she ends up in a situation right out of #MeToo. Even positive stories often come with a bitter reminder of what came before; George Starling, working as a porter on a north-south rail line, is told to direct black passengers to certain cars when the train passes into the south even after Jim Crow has been made illegal, and has to subtly inform these passengers of their right to say no, at risk of his own employment.

Wilkerson’s personal approach to the book does not exclude the academic research on the subject, but she instead sprinkles details and observations of experts on the timing, motive, and extent of the migration – which came in waves, and finally slowed after the Civil Rights Act was passed in 1964 and slowly implemented over the following decade. (And, of course, we now see one party trying to roll it back, along with the Voting Rights Act of 1965.) This is a work of scholarship, yet also a labor of love, as no author could spend so much time and become so invested in a subject unless it were of abiding personal interest to her in the first place. It’s also a potent reminder of why African-Americans today remain at an economic disadvantage relative to whites, and how we are simply repeating the sins of our fathers when we deny black Americans their right to vote, or incarcerate them on nonviolent drug charges, or underfund urban schools as if they were the ‘colored’ schools of the Jim Crow era.

Proof: The Science of Booze.

Adam Rogers’ book Proof: The Science of Booze delivers handsomely on its title: It’s a book about adult beverages, and it will make you want to go drink some, but it also gives quite a bit of information on the (light) science involved in the production of and flavors behind those libations, especially distilled spirits. While some of the stories around booze manufacturing get too bogged down in operational details, there are also magnificent anecdotes within the book, including the best mystery you’ll ever read where the culprit is a fungus.

Rogers divides the book into eight chapters, each revolving around some essential element of alcohol production – yeast, sugar, fermentation, distillation, aging – or its consumption – smell/taste, body and brain, and the hangover. That gives him the latitude to talk about just about anything he wants that’s related to the manufacture of sauce and suds, including but hardly limited to some deep dives on what we do and don’t know about the science of such beverages.

Alcoholic beverages, especially distilled spirits – often called “hard liquors,” produced by putting some alcohol-containing mixture through a still, leading to whiskey (from fermented grain mash, like that created in beer production), brandy (typically from wine), rum (from fermented molasses or sugar cane), vodka (usually potatoes), and so on – have dozens or even hundreds of aromatic and flavor compounds, some of which still aren’t identified, that give them their distinctive tastes and smells. When you sip an aged spirit, often whiskey but applicable to rum and brandy as well, you may pick up “notes” much like you’d identify in good wines or coffees; those notes are specific chemicals or combinations of chemicals formed during the aging process, sometimes on their own and sometimes due to the interactions between the spirit and the wooden (sometimes charred wooden) casks in which they’re housed.

Rogers explores this angle, and many others, with visits to artisanal producers of these various beverages, moving his writing lens from wide shot to close-up and back, extrapolating from individual producers’ experiences to discuss larger points that he can back up (sometimes) with science. He talks about the obsessions distillers have with the shapes of their stills, even trying to reproduce flaws in old stills when it comes time to replace them with new ones. He talks to a barrel maker – apparently this is about as dying as a dying art can be without being, you know, dead – about the specifics of manufacture and the demands of clients. He gets into the lactones formed during the aging of whiskey in wood barrels, a subject so critical it’s even been the topic of academic research. He also compares production of alcoholic beverages from eastern and western cultures; where Europeans relied heavily on Saccharomyces cerevisiae, Japanese beverages such as sake and shōchū come from a mold called koji (Aspergillus oryzae).

Speaking of molds and fungi, the best passage in Proof is, by far, the mystery of the whiskey fungus, practically a detective story about one man’s quest to identify a specific organism growing on buildings near a particular whiskey distillery. The distilling term “angel’s share” refers to the portion of a distilled spirit lost to evaporation during the aging process, usually water but sometimes a mixture of water and ethanol, the latter of which attracts certain fungi that will be found growing on surfaces where the evaporated alcohol may condense. The story Rogers tells is told in greater scientific detail in this free Mycologia journal article – you probably still have that back issue at home – which describes the mycologists’ development of a new genus to encompass these molds, including Baudoinia compniacensis, now identified as the “angel’s share fungus.” Rogers infuses the story with a bit more drama than the journal piece does, of course.

Rogers even gets involved in the debate over wine ratings, where the American Association of Wine Economists (led in part by the perfectly-named economist Richard Quandt) is among the leaders in arguing that the judgment of wine experts like Robert Parker is too subjective to have any value. Quandt and Orley Ashenfelter, who also appears in Ian Ayres’ book Super Crunchers, are in effect the leading sabermetricians of oenology, whereas Parker is … I don’t know, Old Scout or something. Quandt even wrote his own manifesto comparable to Percentage Baseball or early Bill James Abstracts, called “On Wine Bullshit“. Rogers takes a somewhat middle road here, pointing out that truly objective wine measures are impossible until we’ve identified all of the molecules responsible for their flavors and aromas, but I thought he sided with the quants – as will many of you, I’d wager.

As only a casual drinker but one who greatly enjoys a well-aged rum and a well-mixed cocktail, I found Proof (which I listened to as an audiobook) both entertaining and informative, aside from the occasional tangent into manufacturing minutiae. I wish he’d spent a little more time on spirits beyond whiskey, but brandy gets a fair shake and I may merely be expressing my pro-rum bias. If you tipple, you’ll enjoy this book.

The Golden Ticket.

Lance Fortnow wrote a piece for Communications of the Association for Computing Machinery in 2009 on the state of the P vs NP problem, one of the most important unsolved problems in both mathematics and computer science. That article led to the short (~175 page) book The Golden Ticket: P, NP, and the Search for the Impossible, which I recently read in its Kindle edition (it’s also on iBooks); Fortnow does a solid job of making an abstruse problem accessible to a wider audience, even engaging in some flights of fancy describing a world in which P equals NP … which is almost certainly not true (but we haven’t proven that yet either!).

P vs NP, which was first posed by Kurt Gödel in 1956, is one of the seven Millennium Problems posed by the Clay Mathematics Institute in 2000; solve one and you get a million bucks. One of them, proving the Poincaré Conjecture (which relates to the shape of the universe), was solved in 2010. But if you solve P vs NP affirmatively, you can probably solve the remaining five and collect a cool $6 million for your problems. You’ll find a box of materials under your desk.

Of course, this is far from an easy question to solve. P and NP are two classes of problems in computer science, and while it seems probable that they are not equivalent, no one’s been able to prove that yet. P is the set of all problems that can be quickly (in deterministic polynomial time – so, like, before the heat death of the universe) solved by an efficient algorithm; NP is the set of all problems whose solutions, once found, can be quickly verified by an efficient algorithm. For example, factoring a huge composite number is in NP: There is no known efficient algorithm to factor a large number, but once we’ve found two factors, a computer can quickly verify that the solution is correct. The “traveling salesman problem” is also in NP; it’s considered NP-complete, meaning that it is in NP and in NP-hard, the set of all problems which are at least as hard as the hardest problems in NP. We can find good solutions to many NP-hard problems using heuristics, but we do not have efficient algorithms to find the optimal solution to such a problem.

If P does in fact equal NP, then we can find efficient algorithms for all problems in NP, even those problems that are NP-complete, and Fortnow details all of these consequences, both positive and negative. One major negative consequence, and one in which Fortnow spends a significant amount of time, would be the effective death of most current systems of cryptography, including public-key cryptography and one-way hashing functions. (In fact, the existence of one-way functions as a mathematical truth is still an unsolved problem; if they exist, then P does not equal NP.) But the positive consequences are rather enormous; Fortnow gives numerous examples, the most striking one is the potential for quickly developing individualized medicines to treat cancer and other diseases where protein structure prediction is an obstacle in quickly crafting effective treatments. He also works in a baseball story, where the game has been dramatically changed across the board by the discovery that P=NP – from better scheduling to accurate ball/strike calls (but only in the minors) to the 2022 prohibition of the use of computers in the dugout. It’s Shangri-La territory, but serves to underscore the value of an affirmative proof: If we can solve NP problems in deterministic polynomial time (as opposed to nondeterministic polynomial time, where NP gets its name), our ability to tease relationships out of huge databases and find solutions to seemingly intractable logical and mathematical problems is far greater than we realized.

Of course, P probably doesn’t equal NP, because that would just be too easy. That doesn’t mean that NP-complete problems are lost causes, but that those who work in those areas – operations research, medicine, cryptography, and so on – have to use other methods to find solutions that are merely good rather than optimal. Those methods include using heuristics that simplify the problem, approximating solutions, and solving a different but related problem that’s in P. If Fortnow falls short at all in this book, it’s in devoting so much more time to the brigadoon where P=NP and less to the likely real world quandary of solving NP-complete problems in a universe where P≠NP. He also gives over a chapter to the still theoretical promise of quantum computing, including its applications to cryptography (significant) and teleportation (come on), but it seems like a digression from the core question in The Golden Ticket. We don’t know if P equals NP, but as Fortnow reiterates in the conclusion, even thinking about the question and possible approaches to proving it in either direction affect work in various fields that underpin most of our current technological infrastructure. If you’ve ever bought anything online, or even logged into web-based email, you’ve used a bit of technology that only works because, as of right now, we can’t prove that P=NP. For a very fundamental question, the P vs NP problem is scarcely known, and Fortnow does a strong job of presenting it in a way that many more readers can understand it.

If this sounds like it’s up your alley or you’ve already read it, I also suggest John Derbyshire’s Prime Obsession, about the Riemann Hypothesis, another of the Clay Millennium Institute’s six as-yet unsolved problems.

Everything and More: A Compact History of Infinity.

I knew David Foster Wallace was brilliant when I read Infinite Jest, a wildly imaginative, sprawling novel that showcased DFW’s prodigious vocabulary as well as his deep knowledge of a variety of seemingly unrelated subjects. Even with that background, I was flabbergasted by Everything and More: A Compact History of Infinity, in which DFW delves into abstract set theory and other similarly abstruse topics from the history of math, explaining much of it lucidly and with humor until he gets too close to the finish to avoid relying on the reader to understand more of set theory than most readers will.

The book is less an explanation of the number infinity – which isn’t a single number, at least not in the sense that 1 or 5 or π or √2 – than the history of mathematicians’ attempts to deal with it. DFW starts with the Greeks, where most math stories begin anyway, even though the Greeks didn’t like or accept infinity or zero or the irrationals. (Zero came from Indian mathematicians, and reached Europe by way of Arab mathematicians quite a bit later.) The Greeks encountered questions around infinity, particularly in the famous paradoxes of Zeno, who liked to play semantic games around what we now refer to as convergent series – a sum of a series of terms that never ends but that approaches a specific limit as the number of terms grows. (In a related note, DFW fails to answer the question of how Zeno never got punched in the face for coming up with these paradoxes.) This discomfort with infinity continued through the writings of Aristotle and the Catholic Church’s influence over all manner of academic research, which included the idea that infinity was the sole province of God rather than of man, meaning we never got anywhere with infinity until the end of the Dark Ages and the separation of mathematics and religion during the Renaissance.

The pace of the narrative picks up at that point thanks to the explosion of advances in math and related areas of science. The empirical foundation that limited mathematical explorations until the 1600s is tossed aside in favor of more abstract thinking, with appearances by Kepler, Newton, and my homeboy Galileo, as trigonometry and eventually calculus displace geometry as the central philosophy guiding mathematical thinking and what we now think of as number theory. DFW presents an extraordinarily clear explanation of calculus, especially the infitesimals that underpin differentiation and integration and, as the name implies, connect it to the main topic of the book. The goal here is to get to Georg Cantor, the brilliant and mentally ill mathematician whose work remains the foundation of modern set theory and who was the first to recognize that there are different degrees of infinity (ℵ0 and ℵ1, at the least) but died unable to prove that those two infinities had no other infinities between them.

DFW’s writing is clear and witty thoughout the book, with many examples drawn from a former professor of his that help elucidate many of the more recondite concepts around infinity. His explanations of one-to-one mapping and Cantor’s diagonalization method of proving that real numbers are nondenumerable are outstanding, especially the latter, which I knew was true but still wanted to disbelieve because it just sounds impossible. Unfortunately, in the last 40-50 pages of the book, DFW gets so far down the set theory rabbit-hole that I found it increasingly hard to follow, such as discussions of ordinality versus cardinality and power sets of power sets. I got off the math train in college after multivariate calculus with vectors, in part because continuing meant pushing into more abstract areas – linear algebra was the next course, which starts the shift from empirical math to abstract – but that left me a little lost as Everything and More slid into Cantor’s work on the various infinities and work on numerability of sets.

Cantor’s transfinite numbers are the real goal of the narrative here, rather than what I would call the lay opinion of ∞ (what Cantor referred to as “absolute infinity”). A transfinite number is infinite in that it is greater than all of the finite numbers, but has some properties in common with the finites. If you’re familiar with the ℵ0 I mentioned above – the first transfinite cardinal number, corresponding to the number of members (cardinality) of the set of natural numbers (non-negative integers). Cantor’s continuum hypothesis, which appeared first on the famous list of unsolved math problems David Hilbert presented in 1900, posited that there was no set with cardinality (number of members) between the natural numbers and the real numbers (the cardinality of which Cantor designated as ℵ1). The hypothesis itself may be unprovable, at least within the confines of Zermelo-Fraenkel set theory … which DFW mentions but doesn’t explain, concluding instead with the explanation that later work by Kurt Gödel (the incompleteness guy) and Paul Cohen (who proved that the hypothesis and the ZFC’s axiom of choice were independent) set the question aside without really solving it. At least, I think that’s what he said, because I was just barely treading water by the final page. Which also made me wonder if all of these reviewers quoted as giving the book raves actually finished and understood the whole thing; I imagine the number of people who have sufficient math background to follow DFW down to the bitter end is pretty small.

Apropos of nothing else, the biggest laugh I got from the book was when DFW referred to a mathematician as a world-class pleonast, which is the pot writing a three-page letter to the editor about the mote in the kettle’s eye.

Next up: Ned Beauman’s 2012 novel The Teleportation Accident, recommended by a fellow bibliophile I met in New York in August.

The Golden Ratio.

Some recent ESPN links: Analyses of the Jays/Astros ten-player trade and the Brett Myers trade, as well as a big post on players I’ve scouted in the AZL over the last week, including Jorge Soler. The Conversation under the Myers piece has been rather bizarre, as a few (presumably male) readers are saying I shouldn’t have brought up Myers’ 2006 arrest on domestic violence charges. Needless to say, I think these complaints are spurious.

I’m a big fan of mainstream books about mathematics, most of which would probably be best classified as “history of math” even if they’re discussing a currently unsolved problem, such as John Derbyshire’s excellent book on the Riemann Hypothesis, Prime Obsession. (And yes, I’m aware of Derbyshire’s political writing, but that doesn’t change the fact that the Riemann book is very well done.) Mario Livio’s book The Golden Ratio: The Story of φ, the World’s Most Astonishing Number was on my wish list for a long time because it seemed like a perfect blend of the academic and applied branches of mathematics, as the irrational number φ appears in numerous places in nature and (I thought) art. Unfortunately, Livio’s book spends more time talking about where φ is not than about where it is, making this more of a book of mythbusting than of math.

Livio does provide a solid introduction to φ, an irrational number equal to (1 + √5)/2 = 1.6180339887… that has several interesting properties, including:

* φ2 is equal to φ + 1, or 2.6180339887…
* 1/φ is equal to φ – 1, or 0.6180339887…
* If you take any line segment AB and place a point C on it such that the ratio of the longer half to the shorter half is equal to the ratio of the entire segment to the longer half, the ratio in question will be equal to φ
* The ratio between consecutive terms in the Fibonacci sequence – the series 0, 1, 1, 2, where each successive term is equal to the sum of the two terms before it, thus continuing with 3, 5, 8, 13, 21, ad infinitum – approaches φ. The ratio between the 17th and 16th terms is already 1.61800328…
* φ is also the result of the peculiar expression

The golden ratio also appears in many polygons and polyhedrons of interest not just to mathematicians but to artists, architects, and even botanists, as it appears in the spacing of leaves around the stems of many plants. But interest in the ratio has spurred no end of specious or outright fictitious claims about its appearance, including an oft-repeated one about its inclusion in the dimensions of the Parthenon (obtained by gaming the measurements to achieve the desired result) and another claiming Leonardo da Vinci used it in the Mona Lisa (similarly bogus). Livio devotes so much of the book to debunking these and other claims that by the time he gets around to discussing the golden ratio’s actual appearances in art, architecture, and nature, he’s devalued his subject by spending too little time explaining where φ is and too much time explaining where it ain’t.

Next up: I’m a bit behind here, having already finished Michael Ruhlman’s superb The Making of a Chef: Mastering Heat at the Culinary Institute of America, the book that first established him as one of the best writers on food and cooking today.

Folks, This Ain’t Normal.

I’m not a big fan of polemics in general, since, regardless of subject matter, they all tend to share two traits: They are poorly written and lightly evidenced. Joel Salatin’s Folks, This Ain’t Normal: A Farmer’s Advice for Happier Hens, Healthier People, and a Better World fits that description perfectly, with a complete lack of footnotes and scant detail even in anecdotes that should, in theory, help prove his points, and while Salatin is clearly a bright guy, he’s no writer, and whoever edited his book didn’t do him many favors. Yet despite those glaring flaws, and the clear bias with which he writes (one to which I’m sympathetic), there’s still a fair amount of value to be had from reading Folks… because of the questions his arguments on agriculture and our modern, unsustainable food supply will raise in your mind.

Joel Salatin is a self-described “environmentalist capitalist lunatic farmer,” as well as a libertarian, a Christian, and to some degree a bit of a chauvinist, so 350 pages of his thoughts will inevitably contain something to aggravate any reader – a tactic, however, that can have the positive effect of causing readers to investigate Salatin’s claims further to try to debunk them. He runs an extensive, traditional farm in rural Virginia called Polyface, pasture-raising livestock; eschewing the use of pesticides, antibiotics, and genetically modified crops; and employing a holistic approach to land management that relies on natural processes and diets to maintain soil quality, limit water usage, and minimize his carbon footprint.

Salatin follows three main tracks, ignoring some of the extraneous rants in the book such as his thoughts on child-rearing, that are relevant to the consumer:

  1. He explains why industrially-produced food is inferior in quality, safety, and environmental impact to food from individual farmers practicing his style of agriculture.
  2. He blames government regulators, generally in cahoots with large-scale industrial food producers, for masking the true costs of industrially-produced food, making it less cost-effective for small-scale farmers to start and grow their businesses, and limiting those local farmers’ access to markets through suffocating regulations. He even saves some ire for the government’s relationship with Big Oil, since cheap fuel distorts the market for local food, to say nothing of cheap fertilizers.
  3. And he ends every chapter with advice to the consumer on how to improve his/her impact on the food supply, including many admonitions to grow as much of your own produce as you can, as well as to raise chickens in your backyard for their eggs*, feeding them kitchen scraps and using their manure for compost.

* One of our daughter’s best friends in kindergarten has chickens in her backyard, and her mom gave us a half-dozen of the eggs last week. I have never come across any egg with shells that strong, and it was the first time I’d ever seen a greenish egg, which apparently means the hen was an Araucana. The yolks were also very well-defined. If my daughter and I weren’t both so allergic to feathers, I’d set up a coop right away.

As I mentioned earlier, however, Folks, This Ain’t Normal ain’t a great read. He backs up virtually none of what he says unless he can discuss a specific experience at Polyface; at one point, he mentions a centrally-planned city in China that grew up practically overnight, with 250,000 people and gardens on nearly every rooftop, but never mentions one minor detail – the city’s name – without which the story is much tougher to verify. You may nod your head at first to his arguments about corrupt regulators, market externalities, nanny-state policies, or the hijacking of the term “organic,” but his arguments consistently lack evidence. I think most of what he says is right – our government is way too involved in the food supply, and our policies on food and oil have led to poor land usage, soil mismanagement, the inevitability of water crises, and substandard products at the grocery store* – but it would be tough for me to carry out any of these arguments myself based solely on his book.

*Another rant: Have you ever had a truly pasture-raised chicken? The chicken breasts are small, while the legs are larger, because the chickens are more active, building muscle in the thighs and drumsticks (well, what eventually become the drumsticks), while burning off the calories that, in a caged bird, would otherwise lead to larger breasts. (Stop snickering.) I happen to prefer dark poultry meat anyway, since it has more fat, leading to better texture and less dryness, but it’s also a lot more natural; industrally-raised birds’ organs can’t keep up with the muscle growth in the breasts, so they must be slaughtered earlier so they don’t die of organ failure. And, as it turns out, pasture-raised cows and chickens produce more healthful milk and eggs than feedlot or caged livestock does, just as compost-raised produce contains more nutrients than fertilizer-raised produce.

Folks, This Ain’t Normal at least encouraged me to continue what I’ve started in our yard, composting and growing regionally and seasonally appropriate crops, and to be smarter about what I buy and where I buy it. Salatin mentioned The Cornucopia Institute, which ranks organic dairies and organic egg producers on how true their claims of organic practices are. (In Arizona, the executive summary is: Organic Valley and Clover = good, Horizon and Shamrock = bad.) They’ve also led the fight on behalf of almond farmers who want to sell raw almonds to the public, winning a lawsuit allowing California almond farmers to challenge a USDA regulation that forbids the sale of almonds that haven’t been treated with a toxic fumigant or at very high heat, a regulation in response to a salmonella outbreak at one of the nation’s largest industrial nut producers. This kind of policy – where the sins of a large corporation lead to regulations with fixed costs that crush smaller producers – is exactly what Salatin targets when he rants about intrusive, anti-farmer regulations. I had never heard of the Cornucopia Institute before picking up his book, or many of the other books he mentions (such as Gene Logsdon’s memorably titled Holy Shit: Managing Manure To Save Mankind), so Salatin’s book did at least achieve one goal – forcing me to reexamine the food my family eats, from how it’s grown to where we get it. But had he researched and supported his book with more hard data or secondary sources, Folks, This Ain’t Normal might have become a classic in its narrow field.

Next up: As I mentioned on Twitter, I’m working my way through Raymond Carver’s short story collection Where I’m Calling From – and yes, I’m aware of the controversy over his editor’s role in changing some of the text.

Empires of Food.

My 2700-word column on the rehab process from Tommy John surgery, with comments from a TJ surgeon, a rehab specialist, and three pitches who had the operation, is now up for Insiders.

The point of Empires of Food: Feast, Famine, and the Rise and Fall of Civilizations, by Evan D. G. Fraser and Andrew Rimas, is a good one: Civilizations, like ours today, have risen during times of plenty, periods where favorable weather and trading booms have led to rapid growth of populations and cities, but that they tend to fall, often catastrophically, when the food supply is interrupted. We are nearing the end, they argue, of an unusually good era for agriculture, but a cataclysm approaches as climate change, irresponsible farming techniques, water waste, and profiteering all catch up to us and put our future food security at risk. These are all issues that we as consumers should consider when deciding what to eat and where to get it, but a book that’s full of histrionic statements like “cancerous is exactly the state of our twenty-first-century global food empire,” factual errors, and serious omissions isn’t the way to argue the point.

The point of Empires of Food is to show readers the history of the food supply and how civilizations rose and fell with their sources of food, and in that regard Fraser and Rimas largely succeed in their efforts. They use the story of Francesco Carletti (link in Italian; Carletti’s memoir, My voyage around the world, is available used on amazon), a Florentine merchant whose disastrous eight-year trip around the world brought him into contact with many trading societies of the late 1500s and early 1600s, as the narrative hook to connect the various chapters, each describing a key variable in the construction of “food empires.” Those variables are fundamental to agriculture, husbandry, and food commerce – water, soil, distribution channels, refrigeration – with the final additions of “blood” (not just war, but subjugation and oppression in prime growing areas of the world) and money before their one chapter with an iota of hope, describing movements toward organic farming, slow food, and fair trade. The framework is here for a powerful wakeup call to anyone willing to step back and examine his larder and his table.

Unfortunately, when it comes to connecting problems to prescriptions, the authors fall back on hysteria and run light on facts. You can’t do an entire chapter on the declining quality of soil, including descriptions of the effects that heavy tilling and overfarming have on soil erosion rates, without even a single mention of no-till farming as a potential solution, even a partial one, to the very real problem at hand. Similarly, you can’t talk about nitrogen loss through waste and erosion without discussing the same problem of phosphorus, an absolute gating factor on the amount of life that this planet can sustain. (Untreated sewage dumped into the ocean sends loads of phosphorus to to the bottom of the sea, where it’s of little use to life on land.)

The authors’ sins aren’t limited to science or agriculture. They openly praise Marxism with nary a mention of the food shortages that have plagued every society that implemented (always via political repression) Marxist economic policies, including famines in North Korea and milk rationing for Cubans over the age of eight. Meanwhile, they excoriate capitalism and misstate Adam Smith’s “invisible hand” by accusing him of advocating cost-plus pricing. Rather than point out how government subsidies can distort market decisions, or argue for taxes that reflect the externalities they (correctly) point out are not reflected in free-market prices, they want to throw capitalism overboard and send us back to the Middle Ages. They’re similarly dismissive of comparative advantage without considering its wealth-generating capabilities – if you want to argue that localism trumps comparative advantage, acknowledge the latter’s benefits and explain why the former is in our best collective interests.

There are even the sort of tiny errors that don’t necessarily affect the larger point of the book but serve to undermine the credibility of the text because checking these facts is so easy yet wasn’t done. The authors repeat the dubious story of Roman commanders salting the earth around Carthage (per Wikipedia, which has a solid source for this, “ no ancient sources exist documenting this. The Carthage story is a later invention, probably modelled on the story of Shechem.”) They also mention the million-plus city of “San Jose, Texas,” which is probably news to the residents of the San Jose in California or to the residents of San Antonio, Texas.

The intent of Empires of Food is a good one, I think – raising awareness of the fragility of our current infrastructure for feeding the world. It’s certainly relevant to me out here in Arizona, where we depend on dwindling water resources and import much of our food because the local environment isn’t ideal for agriculture (and a lot of local farms out here are selling out to developers). But it’s relevant to anyone in the U.S. because, even though we’re not necessarily the world’s greatest offenders (China is the real villain of the book, although the authors seem too skittish to say so explicitly), we are in the best position to do something about it. The problem with the book is that it gets sloppy and devolves too often into a polemic rather than sticking to well-argued advocacy.

Next up: Nearly done with Charles Bukowski’s bizarre twist on the detective novel, Pulp.

The Immortal Life of Henrietta Lacks.

I mentioned this on Twitter earlier, but The Wire: The Complete Series on DVD is just $73 today on amazon through that link. Disclaimer: I don’t own it, because I’m buying episodes to watch on my iPad (which will cost me more in the long run, actually).

Rebecca Skloot’s The Immortal Life of Henrietta Lacks (currently just $8 in paperback on amazon) is, by far, the best nonfiction book I’ve read since The Ballad of the Whiskey Robber, weaving together a scientific breakthrough, a personal tragedy, and Skloot’s own difficult effort in gathering the information required to write the book into a single compelling narrative that succeeds despite the lack of a definitive resolution or even clear “good” and “bad” sides to the central conflict.

Henrietta Lacks was a poor African-American woman who died very young of cervical cancer in 1951, after receiving radiation treatments at Johns Hopkins that started too late to save her very aggressive form of the disease. A researcher at the school had been trying for some time to grow a long-lasting culture of human cells without success, but the sample he took from Lacks’ cancer turned out to be, as the book’s title implies, immortal, launching a scientific revolution that is partially responsible for many medical miracles we take for granted today – and a commercial revolution from the sale of these “HeLa” cells that has paid her descendents a grand total of zero dollars.

In 1951, there were no laws on medical privacy nor were there laws or even good guidelines on informing patients about what might happen to tissues or fluids collected from them during treatment; a doctor or hospital could use extra samples for research and the patient wouldn’t even know about it, let alone require compensation. A lengthy medical case decided in 1990, Moore v. Regents of the University of California, would later establish that the patient has no right to financial remuneration from such usage (unless, of course, he established those rights in advance, such as by patenting any unique genes*), but in Lacks’ era there were no such rules, nor even understanding that these biological samples could have substantial financial value. (The researcher in the Moore case, David Golde, comes off as particularly sleazy in Skloot’s retelling. He took his own life in 2004.)

*This part resonated a little more strongly with me, as my daughter and I do share a unique mutation that causes an inborn error of metabolism called 3MCC, in which the third step in the breakdown of the essential amino acid leucine produces the “wrong” waste product. (The disease isn’t unique, but our mutation had not been seen before. We’re special like that.) I’m largely asymptomatic beyond an inability to build muscle mass, but my daughter has been hospitalized once for a metabolic crisis and has now been a vegetarian for almost three years to avoid excessive protein intake. I’m still trying to get an answer from Children’s Hospital in Boston on their policies in this area.

What’s worse in this case, however, is that Lacks’ family – widower, siblings, and children – were completely unaware that her tissues had been taken, were being used in research, or had generated millions of dollars in value for others. The family, still poor, still mostly uneducated, and without health insurance, learned about HeLa in the 1970s, and it created a mixture of emotions ranging from fear to anger to wonder (including whether their mother could “feel” what was being done to these cells) that opens up windows on to racial inequalities, , medical ethics debates, and the conflict between public good and privacy rights.

Skloot herself worked on this book for nearly a decade, largely because the Lacks family, scarred by past media attention and con artists looking to latch on to their plight, resisted her efforts to interview them for the book. She eventually forged a strong friendship with Henrietta’s daughter Deborah, a fascinating woman whose emotional growth was probably stunted by losing her mother at such a young age yet who abounds with manic energy that drives her (and Skloot) forward on the research path. Deborah never seems to think of the compensation question, but simply wants to learn about her mother and about what has happened to her cells, perhaps to create a connection that was denied to her when her mother died.

The Lacks family gives the book the narrative structure it needs – the rise of HeLa cells from their origins to a major scientific breakthrough would make for a nice pamphlet, but doesn’t have the drama to drive a work of narrative non-fiction. Following the Lacks family’s struggles from losing Henrietta, from media coverage of the HeLa cells, and from their outrage at how their mother’s cells were used without consent, compensation, or even the correct name (she was often referred to as “Helen Lane” in medical journals), makes the book so powerful. The book requires no knowledge of science beyond a high school biology class, as Skloot provides sufficient explanation of cell structure and replication for anyone to follow along, and her presentation of the ethical issues involved is extremely balanced and surprisingly dispassionate for someone who became very close to the human subjects of her research. As easy as it is to react to the Lacks saga by arguing that her family should at least have been paid after the fact, Skloot points out through her story that it’s not even clear who would pay her (the oncologist who harvested the cells didn’t profit personally from them), and that many of the leaps made through the use of HeLa cells for testing, like Jonas Salk’s polio vaccine, relied in no small part on the easy availability of these cells. It’s as complicated as any good story should be, informative, emotionally involving without resorting to sentimentality, and gives you enough of both sides to make you angry and make you question your own outrage as you read.

Five Equations that Changed the World.

My predictions for 2011 went up yesterday. Podcast and chat on Thursday.

Somehow I forgot to review Michael Guillen’s Five Equations that Changed the World
, a very strong look at five equations and the scientists who developed them that’s explained with very little math at all. Guillen’s target is the lay reader, a term which, since I haven’t taken a physics class since 1990, would include me.

The five equations aren’t hard to guess – they are, in the order in which Guillen presents them, Newton’s Universal Law of Gravity, Daniel Bernoulli’s Law of Hydrodynamic Pressure, Faraday’s Law of Electromagnetic Induction, the Second Law of Thermodynamics (discovered by Rudolf Clausius), and, of course, E = mc2, courtesy of Albert Einstein. But rather than just give the reader the equations and their derivations, Guillen crafts a short story around each, with background on each scientist’s life before the discovery*, the process that led to the development of the equation, and a brief epilogue on some major event or subsequent discovery that hinged on the equation itself. (For example, Newton’s law led to the manned mission to the moon, while Einstein’s led, of course, to the atom bomb.)

* So, does a scientist discover an equation, develop it, or something else? He doesn’t invent it, certainly; these are, as far as we know, immutable laws of our universe. I thought about using “unearth” to describe this process, but it seems to mundane, especially for Clausius’ and Einstein’s contributions. I’m open to suggestions here.

Newton’s and Einstein’s stories are rather well-known, I think, so I would say the most interesting sections of the book were the three that those two bookended. Clausius’ story was probably the least familiar to me, as I probably couldn’t have named him if asked. And what made his story interesting was how many other discoveries or developments had to happen along the way for him to be able to articulate his equation – including the invention of the thermometer, the creation of the calorie as both a unit and as a theory for the source of energy, and the life’s work of Julius Robert Mayer, a Bavarian doctor who first expostulated that all the energy in the universe had to add up to the energy that existed at the universe’s start (that is, the First Law of Thermodynamics), only to find himself rejected and ostracized by both the scientific and religious establishments of the time.

The final section of the book, on how Einstein’s theory of relativity led to the development of nuclear weapons, is a bit poignant as Einstein lived to see the destruction and regretted his role in encouraging President Roosevelt to order the development of the bomb. (I would imagine Einstein realized, however, that since the Germans would have eventually developed it themselves, the Manhattan Project was as much as a defensive move as an offensive one, even though it became an offensive weapon when we figured it out first.) Slightly less interesting, to me at least, was the extent of the family squabbles in the section on Bernoulli, where a pattern of fathers becoming jealous of talented sons tended to repeat itself in a way that would probably land them on Maury Povich today.

If you like the sound of this book but want something mathier, check out my review of Prime Obsession, a book about the development of the Riemann Hypothesis, perhaps the leading unsolved problem in mathematics today.
