(May 2015) Birth of a Theorem: A Mathematical Adventure (5 stars)

A gem: how to go from the abstract to the abstract in a playful way. There is no book like it.

This book takes us through the formulation of the theorems in “On Landau damping” by Clément Mouhot and Cédric Villani. Villani is playful in real life, his research is playful, and the book is playful.

This is a gem for a singular reason. One sees exactly how Villani (or a pure mathematician) goes from abstract to abstract without ever exiting the world of pure and symbolic mathematics, even though the subject concerns a very concrete real-world topic. I kept waiting for him to use simulations or even plots to see how the equations worked. But he did not … he and Mouhot had recourse to outside help (a student or an assistant) for the graphs and he camly noted that they “looked” great. Later in the book he relied on others to do the numerical work… as an afterthought. Most physicists, quants, and applied mathematicians would have played with a computer to get the intuition; Villani just worked with mathematical objects, abstract mathematical objects, and very abstract at that. And this is a big deal for the subject because it belongs to a certain class of problems that do not have analytic solutions, usually requiring numerical approaches.

Landau damping is about something many people are indirectly familiar with. Some history: Fokker–Planck equation, itself the Kolmogorov forward equation, is used commonly as the law of motion of particles (hence diffusions in finance). We quants use it in the main partial stochastic differential equation. In plasma physics it is related to the Boltzman equation, which, by using mean-interraction in place of every interration (mean-field), leads to the Vlasov equation. Landau damping is (sort of) about how things don’t blow up because of some exponential decay. Proving it outside the linear version remained elusive. Villani and Mouhot set to prove it. They eventually do.
One note. I read it in the English translation (because I was in a hurry to get the book), but noticed an oddity that may confuse the reader. “Calcul” in French does not mean “calculation” (in the sense of numerical calculation) but “derivation”, so the reader might be confused about calculations thinking they were numerical when Villani stayed at the abstract/symbolic level.

I would have read the book in one sitting. It grips you like a detective novel.

PS- Some UK BS operator, the type of journalist with an attempt at some PhD in something related to physics who thinks he knows it all and is the representative of the general public trashed the book in the Spectator. Ignore him: the fellow is clueless. Look at reviews by PRACTICING quants and mathematicians. I do not think there is another book like this one.

(November 2014) Modern Aramaic-English/English-Modern Aramaic Dictionary & Phrasebook: Assyrian/Syriac (5 Stars)

There is no way we Levantines can learn the language of our ancestors in an organic way except via nerds insisting on 1) grammar, 2) writing in one of the unwieldy Syriac scripts that one cannot even read on a computer screen without dowloading strange fonts. But Aramaic is still spoken, let us take advantage of it, and figure out how to say “I want to eat mjaddara” rather than memorize poetry by some dead author. Aramaic isn’t a dead language and it is the shame Levantines study Arabic instead of our own heritage.

This book in the Latin alphabet makes both Swadaya and Turoyo alive and easy to read, with all manner of real-world expressions. One can use it to supplement scholarly studies, or just to figure out how modern people speak our ancient language. There are Arabic influences, but the distance between the spoken language and, say, Bar Hebraeus is quite narrow.
I would suggest the authors expand the dictionary. It would be the only one in the latin script.

Most excellent, except for very few and small mistakes. “Debo” in Turoyo is not wolf, but bear.

(April 2014) The Tyranny of Experts: Economists, Dictators, and the Forgotten Rights of the Poor (5 Stars)

The point that top-down development methods are great on paper but have not produced benefits (“so far”) is a point Easterly has made before, heavily influencing yours truly in the formation his own argument against naive interventionism and the collection of “humanitarians” fulfilling their personal growth and shielding themselves from their conscience… This is more powerful: the West has been putting development ahead of moral issues, patronizingly setting aside the right of the people to decide their own fate, including whether they want these “improvements”, hence compounding failure and turning much of development into an agenda that benefits the careers (and angst) of “humanitarians”, imperial policies, and, not least, local autocrats *without* any moral contribution. Talking about a sucker problem.

***

To put it in an aphorism, they didn’t ask the people if they would rather get respect and no aid rather than aid and no respect.

(Jan 2014) Modelling Extremal Events: for Insurance and Finance (Stochastic Modelling and Applied Probability) (5 stars “Indispensable”)

The mathematics of extreme events, or the remote parts of the probability distributions, is a discipline on its own, more important than any other with respect to risk and decisions since some domains are dominated by the extremes: for the class of subexponential (and of course for the subclass of power laws) the tails ARE the story.

Now this book is the bible for the field. It has been diligently updated. It is complete, in the sense that there is nothing of relevance that is not mentioned, treated, or referred to in the text. My business is hidden risk which starts where this book stops, and I need the most complete text for that.

In spite of the momentous importance of the field, there is a very small number of mathematicians who deal with tail events; of these there is a smaller group who go both inside and outside the “Cramer conditions” (intuitively, thin-tailed or exponential decline).

It is also a book that grows on you. I would have given it a 5 stars when I started using it; today I give it 6 stars, and certainly 7 next year.

I am buying a second copy for the office. If I had to go on a desert island with 2 probability books, I would take Feller’s two volumes (written >40 years ago) and this one.

One housecleaning detail: buy the hardcover, not the paperback as the ink quality is weaker for the latter.

(Dec 1/2013) The Kelly Capital Growth Investment Criterion: Theory and Practice (5 Stars)

There are two methods to consider in a risky strategy.

1) The first is to know all parameters about the future and engage in optimized portfolio construction, a lunacy unless one has a god-like knowledge of the future. Let us call it Markowitz-style. In order to implement a full Markowitz- style optimization, one needs to know the entire joint probability distribution of all assets for the entire future, plus the exact utility function for wealth at all future times. And without errors! (I have shown that estimation errors make the system explode.)

2) Kelly’s method (or, rather, Kelly-Thorpe), developed around the same period, which requires no joint distribution or utility function. It is very robust. In practice one needs to estimate the ratio of expected profit to worst- case return– dynamically adjusted to avoid ruin. In the case of barbell transformations, the worst case is guaranteed (leave 80% or so of your money in reserves). And model error is much, much milder under Kelly criterion. So, assuming one has the edge (as a sole central piece of information), engage in a dynamic strategy of variable betting, getting more conservative after losses (“cut your losses”) and more aggressive “with the house’s money”. The entire focus is the avoidance of gambler’s ruin.

The first strategy was only embraced by academic financial economists –empty suits without skin in the game — because you can make an academic career writing BS papers with method 1 much better than with method 2. On the other hand EVERY SURVIVING speculator uses explicitly or implicitly method 2 (evidence: Ray Dalio, Paul Tudor Jones, Renaissance, even Goldman Sachs!) For the first method, think of LTCM and the banking failure.

Let me repeat. Method 2 is much, much, much more scientific in the true sense of the word, that is rigorous and applicable. Method 1 is good for “job market papers” . Now this book presents all the major papers for the second line of thinking. It is almost exhaustive; many great thinkers in Information theory and probability (Ed Thorpe, Leo Breiman, T M Cover, Bill Ziemba) are represented… even the original paper by Bernouilli.

Buy 2 copies, just in case you lose one. This book has more meat than any other book in decision theory, economics, finance, etc…

(Sept 5/2013) A Few Lessons from Sherlock Holmes (5 Stars)

We Sherlock Holmes fans, readers, and secret imitators need a map. Here it is. Peter Bevelin is one of the wisest people on the planet. He went through the books and pulled out sections from Conan Doyle’s stories that are relevant to us moderns, a guide to both wisdom and Sherlock Holmes. It makes you both wiser and eager to reread Sherlock Holmes.

(Ed. I posted on Peter’s Book)

(Aug 31/2013) The Science of Conjecture: Evidence and Probability before Pascal (5 Stars)

Indispensable. As a practitioner of probability, I’ve read many book on the subject. More are linear combinations of other books and ideas rehashed without real understanding that the idea of probability harks back the Greek pisteuo (credibility) and pervaded classical thought. Almost all of these writers made the mistake to think that the ancients were not into probability. And most books such “Against the Gods” are not even wrong about the notion of probability: odds on coin flips are a mere footnote. If the ancients were not into computable probabilities, it was not because of theology, but because they were not into games. They dealt with complex decisions, not merely probability. And they were very sophisticated at it.

This book stands above, way above the rest: I’ve never seen a deeper exposition of the subject, as this text covers, in addition to the mathematical bases, the true philosophical origin of the notion of probability. In addition Franklin covers matters related to ethics and contract law, such as the works of the medieval thinker Pierre de Jean Olivi, that very few people discuss today.

When readers and students ask to me for a useable book for nonmathematicians to get into probability (or a probabilistic approach to statistics), before embarking into deeper problems, I suggest this book by the Late A. Papoulis. I even recommend it to mathematicians as their training often tends to make them spend too much time on limit theorems and very little on the actual “plumbing”.

The treatment has no measure theory, cuts to the chase, and can be used as a desk reference. If you want measure theory, go spend some time reading Billingsley. A deep understanding of measure theory is not necessary for scientific and engineering applications; it is not necessary for those who do not want to work on theorems and technical proofs.

I’ve notice a few complaints in the comments section by people who felt frustrated by the treatment: do not pay attention to them. Ignore them. It the subject itself that is difficult, not this book. The book, in fact, is admirable and comprehensive given the current state of the art.

I am using this book as a benchmark while writing my own, but more advanced, textbook (on errors in use of statistical models). Anything derived and presented in Papoulis, I can skip. And when students ask me what they need as pre-requisite to attend my class or read my book, my answer is: Papoulis if you are a scientist, Varadhan if you are more abstract.

There is something admirable about the school of the Russians: they are thinkers doing math, with remarkable clarity, minimal formalism, and total absence of unnecessary pedantry one finds in more modern texts (in the post Bourbaki era). This is of course surprising as one would have expected the exact opposite from the products of the communist era. Mathematicians should be using this book as a model for their own composition. You can read it and reread it. Professors should assign this in addition to modern texts, as readers can get intutions, something alas absent from modern texts.

I know which books I value when I end up buying a second copy after losing the first one. This book gives a complete overview of the basis of probability theory with some grounding in measure theory, and presents the main proofs. It is remarkable because of its concision and completeness: visibly prof Varadhan lectured from these notes and kept improving on them until we got this gem. There is not a single sentence too many, yet nothing is missing.

For those who don’t know who he is, Varadhan stands as one of the greatest probabilists of all time. Learning probability from him is like learning from Aristotle.

Varadhan has two other similar volumes one covering stochastic processes the other into the theory of large deviations (though older than this current text). The book on Stochastic Processes should be paired with this one.

Here is what I wrote in my endorsement: Emanuel Derman has written my kind of a book, an elegant combination of memoir, confession, and essay on ethics, philosophy of science and professional practice. He convincingly establishes the difference between model and theory and shows why attempts to model financial markets can never be genuinely scientific. It vindicates those of us who hold that financial modeling is neither practical nor scientific. Exceedingly readable.

From the remarks here, people seem to be blaming Derman for not having written the type of books they usually read… They are blaming him for being original! This is very philistinic. This book is a personal essay; if you don’t like it, don’t read it, there is no need to blame the author for not delivering your regular science reporting. Why don’t you go blame Montaigne for discussing his personal habits in the middle of a meditation on war inspired by Plutarch?

I feel guilty for not having posted a review earlier: I owe a lot to this book. I figured out the value of intensity training and maximizing recovery. I use the ideas but with minor modifications (my own personal workout is entirely based on free weights and barbells, but I incur –and accept –a risk of injury). I have been applying the ideas for more than three years. Just get over the inhibitions (and illusions of control) and accept the idea of training less.
Gratitude.

I read this book after completing my exposition of overcompensation, how a stressor or a random event causes an increase in strength, in excess of what is needed, like a redundancy. I was also looking for evidence of convex reaction to stressor, or the effect of a mathematical property called Jensen’s inequality in domains and found it exposed here (in other words, why a combination low dose (most of the time) and high dose (rarely) beats medium dose all the time. The authors presents the evidence for the phenomenon in the following: 1) acute stressors cum recovery beat both absence of stressors and chronic ones; 2) stressors make one stronger (post traumatic growth); 3) risk management is mediated by the deep structures in us, not rational decision-making; 4) winning causes an increase in strength (the latter are more complicated effects of convexity/Jensen’s Inequality).

Great book. I ignored the connection to financial markets while reading it. But I learned that when under stress, one should seek the familiar. Bravo!

The Opposing Shore (5 Stars)

Until I read this book, Buzzati’s “Il deserto dei tartari” was my favorite novel, perhaps my only novel, the only one I cared to keep re-reading through life. This is, remarkably a very similar story about the antichamber of anticipation (rather than “the antichamber of hope” as I called Buzzati’s book), but written in a much finer language, by a real writer (Buzzati was a journalist, which made his prose more functional) ; the style is lapidary with remarkable precision; it has texture, wealth of details, and creates a mesmerizing athmosphere. Once you enter it, you are stuck there. I kept telling myself while reading it: “this is the book”. It suddenly replaced the “deserto”.

A few caveats/comments. First, I read it in the original French Le Rivage des Syrtes (French Edition), not in this English translation, but I doubt that the translator can mess up such a fine style and the imagery. Second, the blurb says Gracq received the Goncourt prize for it. Julien Gracq REFUSED the Goncourt, he despised the Parisian literary circles and by 1951 decided to stay in the margin. He stuck to his publisher José Corti rather than switch to the fancy Gallimard after his success (as Proust did) (or other publishing houses for the fakes and the selfpromoters). Third, this book came out a few years after Buzzati’s “deserto”, but before Buzzati was translated into French. I wonder if Gracq had heard of the “deserto”; the coincidence is too strong to be ignored.

I don’t have time for a full review for now; all I have to say is that we have the account of a person who says it the way it was, revealing the types of truths that don’t fit the New York Times and others pawns. When history is written, this will be used, not the spin by the bankers’ slaves and soldiers (Geithner, Rubin et al.) Bravo Sheila!

If you want an introduction to information theory, and, in a way, probability theory from the real front door, this is it. A clearly written book, very intuitive, explains things, such as the Monty Hall problem in a few lines. I will make it a prerequisite before more technical great books, such as Cover and Thompson.

A charming primer on the paleo idea, with an illustration through the authors own life. I read it in one sitting.

This is a great synthesis of the modularity approach to cognitive science. It covers the entire field and has the right footnotes for the patches.

The style is readable, & the author has an attitude (with is a very good thing, but his jokes are often bland, not aggressive enough). While I strongly disagree with his treatment of morality (I am deontic), I can safely say, so far, that this is not just one of the best books in cognitive science, but certainly one of the most readable.

I read this book twice. The first time, I thought that it was excellent, the best compendium of ideas of social science by arguably the best thinker in the field. I took copious notes, etc. I agreed with its patchwork-style approach to rational decision making. I knew that it had huge insights applicable to my refusal of general theories [they don’t work], rather limit ourselves to nuts and bolts [they work].

Then I started reading it again, as the book tends to locate itself by my bedside and sneaks itself in my suitcase when I go on a trip. It is as if the book wanted me to read it. It is what literature does to you when it is at its best. So I realized why: it had another layer of depth –and the author distilled ideas from the works of Proust, La Rochefoucault, Tocqueville, Montaigne, people with the kind of insights that extend beyond the ideas, and that makes you feel that a reductionist academic treatment of the subject will necessary distort it [& somehow Elster managed to combine Montaigne and Kahneman-Tversky]. So as an anti-Platonist I finally found a rigorous treatment of human nature that is not Platonistic –not academic (in the bad sense of the word).

This book has wonderful qualities that I am certain will be picked up by other reviewers. But I would like to add the following. This is the most profound examination of how nationality is enforced on a group of people, with the internal colonization process and the stamping out of idiosyncratic traits. As someone suspicious of government and state control, I was wondering how France did so well in spite of having a big government. This book gave me the answer: it took a long time for the government and the “nation” to penetrate the depth of deep France, “la France profonde”. It was not until recently that French was spoken by the majority of the citizens. Schools taught French but it was just like Greek or Latin: people forgot it right after they finished their (short) school life. For a long time France’s villages were unreachable.

A great book, a great investigation.

Gary Taubes is a true empiricist. I can’t believe people hold on to the Platonicity of the thermodynamic theory of diet (calorie in = calorie out).

Read it twice, once for the diet, once a a rich document in the history of science.

I read Plato and the Platypus by Umberto Eco, which I found brilliant and was sucked into buying this book thinking it was about the same problem of categories. But Philosophy this is not, or if it is, it is not deep enough to give satisfaction. This is like a brief drink in an airplane lounge with someone funny, smart, witty, but not too funny. So I would give it my lowest rating: 4 stars (as an author I can’t give below that –I just would not review).

Would I buy it again? Perhaps, but only for a plane ride. It left me very very hungry for both jokes and philosophy.

A wonderful book on wisdom and decision-making written by a wise decision-maker. This is the kind of book you read first, then leave by your bedside and re-read a bit every day, so you can slowly soak up the wisdom. It is sort of Montaigne but applied to business, with a great investigation of the psychological dimension of decision-making.

I like the book for many reasons –the main one is that it was written by a practitioner who knows what he wants, not by an academic.

Enjoy it.

I initially bought this book as I was curious about the differences between Eastern & Western traditions, particularly with the notion of theosis –the deification of man. This book goes far deeper, and covers pre-Christian practices (like Stoic thoughts, the deifications of Kings, Roman Emperors, that of private citizens who committed symbolic acts –such as Antinous, Hadrian’s obsession, who drowned to “save” mankind and other sotirologies).

The book was initially Russell’s doctoral thesis, which, as far as I can guess from the dates, had to have been completed when he was in late middle age. But he made it very readable, free of the theophilosophical jargon of similar texts. He still has quotes in the original language and it is a true piece of scholarship.

I spent my life focusing on the errors of statistics and how they sometimes fail us in real life, because of the misinterpretation of what the techniques can do for you. This book is outstanding in the following two aspects: 1) It is of immense clarity, embedding everything in real situations, 2) It uses the real-life situation to critique the statistical model and show you the limit of statistic. For instance, he shows a few anecdotes here and there to illustrate how correlation between two variables might not mean anything causal, or how asymptotic properties may not be relevant in real life.

This is the first statistics book I’ve seen that cares about presenting statistics as a tool to GET TO THE TRUTH.

The Birth Stochastic Science: Rewriting the History of Medicine

Controlled experiment can easily show absence of design in medical research: you compare the results of top-down directed research to randomly generated discoveries. Well, the U.S. government provides us with the perfect experiment for that: the National Cancer Institute that came out of the Nixon “war on cancer” in the early 1970s.

“Despite the Herculean effort and enormous expense, only a few drugs for the treatment of cancer were found through NCI’s centrally directed, targeted program. Over a twenty-year period of screening more than 144,000 plant extracts, representing about 15,000 species, not a single plant-based anticancer drug reached approved status. This failure stands in stark contrast to the discovery in the late 1950s of a major group of plant-derived cancer drugs, the Vinca Alcaloids -a discovery that came about by chance, not through directed research.”

From Happy Accidents: Serendipity in Modern Medical Breakthroughs, by Morton Meyers, a book that just came out. It is a MUST read. Please go buy it. Read it twice, not once. Although the author does not take my drastic “stochastic tinkering” approach, he provides all kind of empirical evidence for the role of design. He does not directly discuss the narrative fallacy(q.v.) and the retrospective distortion (q.v.) but he certainly allows us to rewrite the history of medicine.

We did not realize that cures for cancer had been coming from other brands of research. You search for noncancer drugs and find something you were not looking for (and vice versa). But the interesting constant:
a- The discoverer is almost always treated like an idiot by his colleagues. Meyers describes the vicious side effect of “peer reviewing”.
b- Often people see the result but cannot connect the dots (researchers are autistic in their own way).
c- The members of the guild gives the researcher a hard time for not coming from their union. Pasteur was a chemist not a doctor/biologist. The establishment kept asking him “where is your M.D., monsieur”. Luckily Pasteur had too much confidence to be deterred.
d- Many of the results are initially discovered by an academic researchers who neglects the consequences because it is not his job –he has a script to follow. Or he cannot connect the dots because he is a nerd. Meyers uses Darwin as the ultimate model: the independent gentleman scholar who does not need anyone and can follow a lead when he sees it.
e- It seems to me that discoverers are nonnerds.
Now it is depressing to see the works of the late Roy Porter, a man with remarkable curiosity and a refined intellect, who wrote many charming books on the history of medicine. Does the narrative fallacy cancels everything he did? I hope not. We urgently need to rewrite the history of medicine without the ex post explanations. Meyers started the process: he provides data for modern medicine since, say, Pasteur. I am more interested in the genesis of the field before the Galenic nerdification.

One of the author, Baz, gave me a copy of this book when it came out and it went to sleep in my library as I was not in a finance mood. I forgot about it until this week as I was stuck on a problem related to risk-neutral pricing and the Girsanov theorem concerning changes in probability measure. I looked at every passage on the the subject until I hit on it. Then I realized that I should have read it before: it is a condensed, but extremely deep , and complete exposition of the subject of theoretical finance.

No financial book has the clarity of this text.

Other quant books do not have such notions as “pricing kernel” and economic theoretical matters. I would recommend it as a necessary piece of the “quant” toolkit. Every quant should have it as a background tool as the usual quant literature is standalone and devoid of these concepts.

Thinking and Deciding (5 stars)

People vote with their wallet –particularly when they do it a second time, when they REpurchase. Those who believe in the “revelation of preferences” should note that there are books one buys again when a copy is lost –particularly when they are read cover to cover.

I am buying another copy of this book as mine was lost or misplaced. That should speak volumes.

As I am teaching the statistical mechanics part of a graduate class in mathematics,I was looking for a textbook on complex systems & statistical physics with derivations, intuitions, and some physical examples. I did not realize that I was looking too far –Sornette, with hom I correspond regularly, is well known for his contributions and his prolific output (actually some physicists make fun of the quantity of papers he writes). So his book did not come to mind. I once stumbled on a problem with the derivation of preferential attachments;he recommended his book, which I took with a grain a salt. After spending some time working the derivations on scalable laws, extreme value theory, renormalization groups in this book, I elected to use it as my textbook. There is no equivalent. I have a dozen such yellow manuals; this one is complete and ultimately clearest.

I do not know of a better textbook.

If you like the thinker’s prose, the so-called “romantic science”,a style attributed to the Russian neuroscientist A. R. Luria,which consists in publishing original research in literary form, you would love this book. Clearly intellectual scientists are vanishing under the weight of the commoditization of the discipline. But once in a while someone emerges to reverse such setbacks.

Goldberg, who was the great Luria’s student and collaborator, is even more colorful and fun to read than the master. He is egocentric, abrasive, opinionated, and colorful. He is also disdainful of the conventional beliefs in neurosciences –for instance he is suspicious of the assignment of specific functions, such as language, to anatomical regions. He is also skeptical of the journalistic “triune” brain. His theory is that the hemispheric specialization is principally along pattern matching and information processing lines:the left side stores patterns, while the right one processes novel tasks. It is convincing to see that children suffer more from a right brain injury, while adults have the opposite effect.

There is a little bit of open plugging of Goldberg’s for-profit institute;he would have gotten better results by being subtle. A fre minor points. I did not understand why Goldberg discusses “modularity”, of which he is critical, as if it were the same thing in both neurobiology and in cognitive science. In neurobiology, modularity implies regional localization, while cognitive scientists (Marr, Fodor, etc.) make no such assumption: for them it is entirely functional and they would be in great agreement with Goldberg. Also I did not understand why he attributes the language instinct to Pinker, not Chomsky, and why he makes snide remarks about behavioral scientists like Kahneman and Tversky. But these are very minor details that do not weaken the message (I still gave the book 5 stars). I am now spoiled; I need more essays by opinionated, original,and intellectual, contemporary scientists.

If your interests are limited to mystery books, nothing else, this book is not for you.

I initially bought this book because of the title, thinking that we would have a female version of Her Professor Dr Dr (Hon.) Moritz-Maria von Igenfeld, the Pninish uberscholar philologist who wrote the seminal Portugese Irregular Verbs (“after which there was nothing left to discuss about the subject, Nothing.”). I was curious to see how he would present a female version of such scholar.

He did not. Nor was it a detective story, although there is an element of suspense. This book is about Applied Ethics, a subject about which the author seems to know a bit. It also makes you feel like leading a quite thinking life in Edinburgh.

I don’t want to spoil the story but I felt that I was reading a detective story until I realized what it was…

This book is a great attempt at finding some universality based on systems in a “critical” state, with departures from such state taking place in a manner that follows power laws. The sandpile is a great baby model for that.

Some people are critical of Bak’s approach, some even suggesting that we may not get power laws in these “sandpile” effects, but something less scalable in the tails. The point is :so what? The man has vision.

I looked at the reviews of this book. Clearly a few narrow-minded scientists do not seem to like it (many did not like Per Bak’s ego). But the book is remarkably intuitive and the presentation is so clear that he takes you by the hand. It is even entertaining. If you are looking to find flaws in his argument his pedagogy allows it (it is immediately obvious to us who dabble with simulations of these processes that you need an infinite sandpile to get a pure power law).

Another problem. I have been ordering the book on Amazon for ages. Copernicus books does not respond to emails. I got my copy at the NYU library. Bak passed away 2 years ago and nobody seems to be pushing for his interest and that of us his readers (for used books to sell for 99 implies some demand). This convinces me NEVER to publish with Springer.

I spent some time looking for a simple bedside aggregation of the various topics associated with the psychology of decision making and the various perceptual biases, without finding much. Most of the books are excellent; but, aside from this one (and Jon Baron’s) they are usually compilation of original research. I like to have a readable consolidation of the material not far from my figertips. I was lucky to have found this book, which provides a wonderful and comprehensive coverage of the topics.

It is limpid, precise, illustrative, showing a wonderful clarity of mind.

Now the bad news. The author passed away recently at the age of 48.

The (Mis)behavior of Markets (5 stars)

I have been involved in the professional practice of uncertainty for almost all of my adult life. I’ve seen and read books and papers on the subject of deviations, with “this is interesting” here and there. I closed this book feeling that it was the first book in economics that spoke directly to me. Not only that, but this astonishing simplicity, realism, and relevance of the subject makes it the only work in finance I’ve read that seemed to make sense.

I cannot make justice to the book other than say 1) MAKES SENSE, 2) EASY TO UNDERSTAND, 3) PRESENT SUCH EMPIRICAL VALIDY that it will make financial economists (charlatans) have to hide deeper from the common man with their complicated “mathematics”.

Mandelbrot brought fractals into mathematics by going to the general public. He is doing the same here: pleading to the regular man unburnded with knowledge of economics.

You are a hot shot in a company, though not the boss. You are paid extremely well, but, again you have plenty of bosses above you (say the partners of an investment firm). Is it better than deriving a modest income being your own boss? The counterintuive answer is NO. You will live longer in the second situation, even controlling for diet, lifestyle, and genetic predispositions.

Marmot spent years poring over data; he left no stone unturned and is well read in the general literature on human nature. This idea of people living longer when they exert control over their lives has not spread yet. That people lead longer lives when they trust their neighbors and feel part of a community is far reaching. Just think of the implications on social justice etc. Also think that everything you learn on human preferences and well-being in both economics and medicine is either incomplete (medicine) or bogus (economics).

The book is well written, humorous at times, and rigorous –it reads like a well-translated scientific paper. But it feels that it is just the introduction to a topic. Please, write the continuation.

I find it clear in its exposition of the problems of modern psychology. In addition to the ideas of “satisficing”, it displays the major ideas in the psychology of happiness (hedonic treadmill), along with the theories of choice & decision making.

Clearly this is not for scholars as it is extremely diluted and slow at times; this is a popular science book. Still, I could not put it down.

I could not put it down. It hit me at some point that I was at the intersection of readability and scholarship. Clearly the value of this book lies beyond its readability: Gottlieb is both a philosopher and a journalist (in the good sense), not a journalist who writes about philosophy. He investigates and provides a fresh look at the material: For instance what we bemoan as the flaws of Aristotelianism during the scholastic period came 2000 years after his work. Aristotle had an empirical bent –his followers are the ones to blame.

I liked his constant questioning of the labels put on philosophers and philosophies by the second hand readers.

Clearly he missed a few authors who deserve real coverage like Algazali, but I take what I can get.

The only other readable history of philosophy is Russell’s. This one was less hurriedly put together.

Someone should bug the author to hurry with the sequel on Locke, Hume, etc.

Intellectuals in the Middle Ages (5 stars)

Excellent, be it only for the presentation of the difference between the pompous scholastic thinker laboring in the academy and the other nonacademic humanist laboring in the the “luxe calme et volupte” of his study.

Another of the attributes is the readability of the work Le Goff is a gifted writer.

I read the review of Simon Blackburn trashing the book: Eco made a few mistakes concerning the two dogmas of empiricism (he confused Davidson’s work with Quine’s first dogma). So I am sure many readers hesitated after a review by such a rigorous big gun thinker as Blackburn.

When I started reading the book I was taken aback by the combination of depth and the vividness of the style. Eco is sprightly and alive, something that cannot be said of many philosophers dealing with the subject of categories.

The notion of categories is not trivial: you need a simple conditional prior to identify an object; it is a simple mathematical fact. You need to know what a table is to see it in the background separated from its surroundings. You need to know what a face is so when it rotates you know it is still the same face. Computers have had a hard time with such pattern recognition. A PRIOR category is a necessity. This was Kant’s intuition (the so-called “rationalism”). This is also the field of semiotics as initially conceived. Eco took it to greater levels with his notion of what I would call in scientific language a compression, a “simplifation”. This leads to the major problem we face today: what if the act of compressing is arbitrary?

Not just very deep but it is a breath of fresh air to see such a philosophical discussion nondull, nondry, alive!

This is not a polularization /adult-education style presentation. Magee sees things form the inside; it is his own formation of philosophical ideas & techniques that we witness.

Magee was close enough to Popper to present us with his ideas first-hand (nobody reads Popper; people read about him). He also debunks a few idiotic myths about Wittgenstein as an atomist (Magee read W and realized that people read commentary on him rarely the original).

Magee writes with the remarkable clarity of the English philosophers/thinkers.

Philosophy has been under severe challenge from science, literally eating up its provinces: philosophy of mind went to neuroscience; philosophy of language to Artificial Intelligence and Computer Science,etc. This book shows that there is a need for someone to just specialize in the TRUTH, its scructure, its accessibility, its INVARIANCE.

Aside from the purely philosophical answers that scientists were grappling with, the book is like a manual for a new regimen in philosophy. It reviews everything from epistemology to the logic of contingency, with insights here and there about such topics as the observer biases (about computing probabilities when our existence has been linked to a particular realization of the process).

I am not a philosopher but a probabilist; I found that this book just spoke to me. It certainly rid me of my prejudice against modern philosophers.

Humphreys is the only person I know of who can work on nonhuman primates, write philosophy, and edit a literary magazine.

The latter shows in this writing: I read this book in a single sitting. You may not agree with the ideas on consciousness (I don’t) but you get a clear exposition of all the work from Descartes to McGinn. Also if you want to figure out what Dennett is saying it helps to read this book first.

Maggie Mahar had the courage to take a look at what was behind all of this religious belief in markets. Clearly I do not understand how she was able to work as a journalist when she has the attitude and mindset of a truth-seeker. I spent some time looking at the difference between her book and Lowenstein’s: not even possible to start comparing. One needs to be a trader to value her work.

I Think, Therefore I Laugh (5 stars)

I found this copy last week at Waterstone in London . It made me feel the plane ride was very short! I should have bought a couple. This is a great book for a refresher in analytical philosophy: pleasant, clear. Great training for people who tend to forget elementary relationships.

I did not know that JAP was a logician. Go buy this book!

The only competition is “Think” by Blackburn (rather boring).

This is a great book but I felt something cold inside of me while reading it. I don’t know if it is cultural (the modern English philosopher’s fear of displaying passion) but I had the feeling to talk to a plumber who developed expertise in abstract concepts and their relationships just as if they were small plumbing problems fitting together under a generalized plumbing theory. Perhaps philosophy needs to be treated like that, just like engineering –but not for me. At least I give myself the illusion of doing something more…literary.

Colin McGINN teaches us that we need nevertheless to master the art of clarity of both thought and exposition. He write with perfect clarity: a clear, unburdened, unaffected, UnFrench UnGerman philosophical prose.

The book has a presentation of the Kripke idea of naming as necessity of such clarity that I felt actually smart reading it.

Other than that there is the feeling of drabness in part of the book of the type I got once at a conference in an industrial city West of London.

I became interested in this book while reading a review panning it in The Nation by one Danny Postell (thanks to Arts & Letters Daily). Clearly it was visible that John Gray was after a definition of humans that integrates our discoveries from cognitive science, that we are just animals who are curse with intelligence, sufficient intelligence to figure out things but insufficient to control our actions –what I call the ability to rationalize (“much of the difference between us and other primates lies in our being considerably better than them at explaining our behavior”). Postel (I have no clue who he is and what kind of training he has in modern scientific thought but I am sure that he is sufficiently burdened with a knowledge of humanities verbiage to get the book wrong); Postel was panning Gray exactly for the reasons that would make this book insightful. So I BOUGHT THIS BOOK BECAUSE OF A BAD REVIEW!

What struck me with this book is that Gray converges in opinion to the discoveries of the New Science of Man –without quoting from neurobiology, cognitive science, evolutionary psychology, the Kahneman-Tversky Heuristics & Biases Tradition. It is remarkable that he identified the ills of the so-called humanist tradition without assistance from the works on rationality posited by Kahneman and his peers.

This book is worth 4 stars because here we have a literary intellectual who manages to break through the mud in his knowledge. It would have been worth 5 stars had Gray read a few more works in scientific thought beyond Darwin. Anyway I am very impressed with a literary intellectual capable of this empirical and realistic view of man.

Mapping the Mind (5 stars)

I started my interest in neurobiology in December 1998 after reading a discussion by Rita Carter in the FT showing that rational behavior under uncertainty and rational decision making can come from a defect in the amygdala. Since then I’ve had five years of reading more technical material (Gazzaniga et al is perhaps the most complete reference on cognitive neuroscience) and thought that I transcended this book.

But it was not so. I picked up this book again last weekend and was both astonished at a) the ease of reading , b) the clarity of the text and c) the breadth of the approach! I was looking for a refresher as I am trying to capture a general idea of the functioning of that black box and found exactly what I needed without the excess burden of prominent textbooks.

Very pedagogical.

I read here and there comments by neuroscientists dissing the book over small details perhaps invisible even to experts. I just realize that Carter should keep updating it, as it is invaluable in my suitcase when I travel! I do not conceal my suspicion of “science writers” and journalists more trained in communicating than understanding and usually shallow babblers but Carter is an exception. Perhaps the science of the mind requires breadth of knowledge that she has. She is a thinker in her own right not just a “medical journalist”.

The Mind Doesn’t Work That Way (5 stars)

This critique of the computational theory of mind and the pan-adaptionist tradition is clearly so honest that it goes after the ideas promoted by Fodor’s own 1983 watershed book “The Modularity of Mind”. In brief the essay is an attack on massive modularity by saying that there are things after all that escape the programming (encapsulation and opacity are key: how can we talk about something OPAQUE? We know nothing about a few critical things…).

Granted the book is horribly written (that is Fodor’s charm after all) but his argumentation is so ferocious that he ends up loud & clear.

The man is critical of his own ideas, and of the current in thought that he he helped create –one may use Fodor-1 against Fodor-2. Perhaps persons I hold in highest respect are those who go after their own ideas!

Bravo Fodor. Even if I do not agree I can’t help admiring the man.

Consciousness: An Introduction (5 stars)

I am glad to find a complete book dealing with all aspects of consciousness in CLEARLY written format, with graphs and tables to facilitate comprehension. The book covers everything I had seen before from Artificial Intelligence to Philosophy to Neurology to Evolutionary Biology.

Say one wants to get an idea of Dan Dennett’s theory of consciousness (without having to get through Dennett’s circuitous, unfocused and evasive prose) or Searle’s Chinese room argument or Turing’s test or Chalmer’s position or Churchland’s neurophilosophy or a presentation of research on the neural correlates of consciousness…Everything I could think about is there.

I read the book once when it came out. Since then I’ve had the chance to reread it a few times, discovering more and more layers as my interests take me in new directions(for instance the discussion on the happiness treadmill goes to the core of the current discussions in the economics of happiness). I now carry a copy on my trips as I can kill time in airports by perusing random sections.

The book is so readable as to perhaps set a standard. Yet it is complete in the sense that it covers more of the evolutionary thinking than meets the eye. I didn’t realize it until I went to the site www.meangenes.org and got into the more technical research material.

The author aside from the problem of crashes presents an insightful exposition of tipping points. I don’t know why his approach makes it clearer and deeper than those of Watts and Barabasi –is it due to his using financial markets as a base? or his being an expert at fat-tailed dynamics?

His work builds on the “abyssus abyssum invocat” (panic begets panics) and the dynamics of compounding disequilibria. In addition the notion of “CRITICAL POINT” is made very clear.

Honestly I don’t care for the idea of crashes; the same concepts can apply to sudden and unexpected euphorias.

I learned more from this book than any other on disequilibrium.

Robert Shiller has the remarkable ability to think independently and the courage to propose ideas that to middlebrow thinkers may sound speculative.

Think of what your reaction would have been had someone discussed risk sharing (insurance) before it became popular. A lunacy people would have thought. Most risk management is like that: we think backwards with the benefit of past history and find these ideas obvious. They were not at the time.

Throughout his career Shiller stood for unpopular ideas and was proven right (his 1981 paper on volatility, his 2000 discussion of the bubble). I would read and re-read this book.

The book that carried the most influence on my thinking this year (I went back to it half a dozen times).
This is a clearly written presentation of our inability to forecast our own behavior and to predict our emotional reactions to positive and negative events. One would think that the repetition of experiences with consistent forecasting biases would lead to some correction but this is not the case.

We are more resilient than we think (“immune neglect”). The book also discusses the reversion to baseline happiness after what we thought would bring a permanent improvement in our moods (yet we never learn from it).

The most important part covers the “hindsight bias” how we see past misfortunes as deterministic –and how we can confront negative emotions by making them even more so (by creating a narrative that make the events appear unavoidable).

The book is a great exposition of modern scientific thinking and understanding of the nature of man–but it spends some time on topics that are entirely obvious outside of the humanities academia. Indeed Pinker gives them too much respect by honoring them with such a lengthy reply.

His other two books are much better.

As a speculator I learned to take the best from books and ideas without arguments (many readers seem to be training to be shallow critics)–good insights are hard to come by. One does not find these in the writings of a journalist. There are some things personal to the author that might be uninteresting to some, but I take the package. The man is one of the greatest traders in history. There are a few jewels in there.

The man did it. I’d rather listen to him than read better written but hollow prose from some journalist-writer.

Very useful book, particularly in what concerns alternative L-Stable distributions. True, not too versed in financial theory but I’d rather see the author erring on the side of more physics than mathematical economics. As an author I don’t ask much from books, just to deliver what they indend. This one does.

Clear historical description of Einstein/Bachelier. Hopefully one day we will call derivatives pricing the Bachelier valuation.

The book in short provides an excellent perspective on the statistical approach to asset price dynamics. Very clear and to the point.

Tartar Steppe (Verba Mundi) (5 stars)

I never understood why the book never made it in the Anglo-Saxon world. Il deserto is one of the 20th century’s masterpieces.

The best intuition builder in both statitics and econometrics. I have been reading the various editions throught my career. Please, keep updating it, Peter Kennedy!
