Turn an extra page before calling it boring, 25. August 2008
At the beginning I found the content of this book a bit trivial and even boring. I persevered because I received it as a gift. Then some pages further a collection of psychological experiments are presented with their results. I have been amazed by the creativity of experimental psychologist when it comes to test their hypothesis and by broad set of applications they have. In particular, I found particularly enlightening an empirical result about 'learned helplessness'.

If only I had listen to Jim's advice at the time he published the book ;), 25. August 2008
Did you know that, even at record high prices, for an equivalent volume, the price of crude oil represents a ridiculous proportion of the price of cocacola. This is the type of insights that the author shares in this book. He also emphasizes the most significative orders of magnitude. Expost one is forced to recognized that any investor who would have followed Rodger's advice, at the time he published them, would have performed incredibly well. I was afraid that this book was only disguised promotion for the index initiated by the author: it is not. Instead it is a pleasant up to date introduction to investment in commodity and to the drivers of this market.

An excellent reference, 25. August 2008
At the beginning of the book the author explains his goal: find the balance between mathematical formalism and engineers' more pragmatical approach. In my opinion he reached his goal. It is an excellent book which also introduces the Fourier Transforms, PDE's and some topics from complex analysis. As usual with this SUMS series from Springer there are exercises with more or less detailed solutions. Every topic is introduced gently so that reasonable prior mathematical knowledge is required (Except for the chapter about PDE's where the pace changes abruptly and some prior familiarity with the subject is necessary). However, this text is of minimal use for statistics and probability; the intended audience is engineers. Most examples come from electrical engineering and signal processing.

How and when the mortgage market initiated, 25. August 2008
More than ever there is meaning to this story. The author gives us an insider's view of the very first days of mortgage securitization. It is difficult not to be taken aback about how this market was originally designed to match the interests of the few who initiated it. At the time, the technical advance in the Fixed Income area of the S bros such that they could trick the Federal decision taker in whatever advantaged them. Only an insider could give such a microscopic description of greed and excess but also how financial innovation occurs to a young salesperson. And only an insider could point out the precise point when the decline started, up to the consequences we know now. What is funny though is that figures will look quite modest to anyone familiar with finance today. I learned a lot reading this book which was given to me when I was a trainee in fixed income; however it really puts aside the genuine value added that financial industry has once striped of excesses, moral hazard.

Very relaxing in extreme circumstances, 25. August 2008
More and more, defeat and failure are acknowledged as being a part of creativity and innovation; to the point that today, every economist is familiar with the idea of 'creative destruction'. This book is about how to admit defeat in a wise and elegant way, and thus how to alleviated the pain. How to welcome it without resentment when one's best has been put in the effort. It is this author's best.

To be combined with a book on power laws, 25. August 2008
This is a classical referenced and the main hypothesis of this book is now well known. It is about that particular point when an output (epidemic) spreads in a disproportionate way with respect to the input. If this book was only about that, one could grasp the idea in a few lines. The author shows what settings do favour the spreads of an epidemic. He does it by presenting different personality profiles. What combination of profiles will make your idea turn into the new trend; a bit like what chemical compounds would make lead turn into gold. Combine it with power laws à la Taleb or Sornette and you get a glimpse of the type of social sciences which are desirable no matter what your scientific tastes are.

A generalisation more accessible than the particular case, 25. August 2008
Personally I found easier to go through the material if this book than any other book on financial math which only presents Brownian motion. It is absolutely rigorous but also addresses the problems found in practice. For example, calibration (i.e. the inverse problem) is not some subsidiary chapter; it is motivated from the first chapter and extensively treated later on. By half of this book the most advanced research will be within your reach. It is simply the best book on financial math there is. Do not bother reading the classical books which treat Brownian motion only, they are more difficult than this one.

A very convincing hypothesis, 25. August 2008
This text takes the reader trough the rise and fall of the main ancient empires seen from the perspective of the immune system. How much time did it take for a given parasite and to our ancestors to adapt to each other and how did it shape human history. You will be surprised by the explanatory power of this hypothesis.

A very dense source of financial knowledge, 25. August 2008
There are two things that delighted me about this book. First, the discussion about the qualitative approach to uncertainty: it shown to be as rigorous as one has it. It is also shown not to be the opposite of a more quantitative (i.e. frequentist) approach. Then the author motivates risk management inside the firm with 'backoftheenvelope' computations. He demonstrates that it has value to the external investor and that diversification is no substitute for it. I did not encounter this argumentation anywhere else. And there is much more in this book: decomposition of trades, risk management via a very accessible presentation of scenario analysis, historical simulations as well as parametric simulations. This book is the clearly the work of someone with quantitative skills who has the genuine desire to share his knowledge

On the role of probability as a theory in casino games, finance and information, 25. August 2008
This book is a chronicle about what information theorists, gangsters and politicians have in common, but not only. Among many other things, it introduces some non trivial concepts of ruin theory that are captivating. Personally, it has been my first encounter with the 'Kelly criterion'. The author has an incredible talent to decompose the most advanced ideas and to present them in a very accessible way. In fact, it is a very dense text with respect to the information it contains. And it is not information that is to be found commonly in other books on finance or randomness.
