Does God Play Dice ? Dar eu am început să devin ceva mai înţelept Puţin respect şi pentru ceilalţi ce ziceţi? Mulţi cred că cercetarea ştiinţifică e o activitate artificială şi încă mai mulţi par să creadă că matematica abstractă e doar un joc intelectual «Ieşiţi din turnurile voastre de fildeş şi trăiţi în lumea reală» strigă ei De obicei prin reţelele de televiziune care n ar fi existat fără oameni de ştiinţă ingineri şi matematicieni Hmmm? Nothing particularly new but I guess I've read enough of these now that that was pretty likely It's a very good overview of the whats and whys of chaos theory comparable to Gribbin's Deep Simplicity though maybe slightly less accessible The final chapter is marred by an ill conceived rant at a straw man of reductionism but nobody is perfect

By Ian Stewart – Nimic din universul nostru – de la particulele elementare la corpurile cereşti – nu are un comportament complet predictibil Un robinet care picură dinamica ecNimic din universul nostru – de la particulele elementare la corpurile cereşti – nu are un comportament complet predictibil Un robinet care picură dinamica ecosistemelor epidemiile de pojar capriciile meteorologice evoluţia bursei – toate acestea prezintă stranii tipare de comportament care au ajuns să fie explicate odată cu apariţia teoriei haosuluiCunoscut cititorilor din România prin celelalte cărţi publicate la Humanitas – Doar şase numere This book is a solid interesting and insightful introduction to Chaos theory the relatively recent and fascinating branch of physics that deals with the study of nonlinear dynamical systems exhibiting extreme sensitivity to initial conditions in which seemingly random complex behavior can derive from simple deterministic innocuous looking euationsThe material treated by the book is pretty standard for a good introduction to the subject I think that it could actually be used as a supporting book for a non mathematical undergraduate course in the subject It would also be valuable reading for a course in the philosophy of science as it contains in a few places fascinating discussions about the scientific method about the contrast between the paradigm of modelling through partial differential euations and the methods of chaos theory about the real meaning of complexity and of randomness and the challenges posed by chaotic behavior to the experimental verification of mathematical models and other similarly interesting subjects Overall it is a uite enjoyable book written with conceptual clarity and one of the very few books about chaos theory that at least attempt to seriously get into the subtle conceptual elements of this discipline However it must also be said that the subtitle “the new mathematics of chaos” is misleading this is not a book about the mathematics of chaos but it's about the conceptual features of the phenomenon But even if devoid of mathematics it can be really fully appreciated only by readers who had some prior knowledge of basics of topology and of partial differential euations From this perspective it really leaves you wanting for a mathematical uantitative approach – and this is uite unsatisfactory – this book could so easily have been a real gem The lack of mathematical detail is occasionally frustrating for example Lorenz simplified mathematical model for atmospheric convection is shown but there is no explanation of how these three differential euations are derived nor any explanation of what the variables in the euations actually mean; another example the concept of fractal dimension is introduced but no mathematical detail is presented; even relatively simple examples like the driven oscillator or the double pendulum are not treated mathematically – something which the author could have at least done as a separate item in an appendix at the end of the book On the other hand it is not an over simplistic book many fascinating features of chaos theory are addressed in a pretty rigorous occasionally deep but always approachable manner there is an excellent introduction to the relationship between the topological features of the phase space and the overall behavioral pattern of the dynamics of the associated system in particular I enjoyed the part about Poincare sections and how they relate to phase portraits and attractors the logistic mapping is treated beautifully and the introduction to the concept of strange attractors is uite enjoyable possibly one of the best I have seen the same applies to the concept of self similarity and how the the enormously varied range of possible mappings gets lumped together into universality classes where within each class the scaling ratio is always the same for example the famous 4669 for the class of mappings structurally similar to the logistic mapping the frustratingly complex phenomenon of turbulence is treated really well the relationship between strange attractors and their fractal dimension is very interesting Overall it is a very good introduction to chaos theory and nonlinear dynamics recommended to readers with no prior exposure to this fascinating discipline who are interested in a serious but non mathematical treatment of the subject

De ce frumuseţea este adevărul şi Îmblânzirea infinitului – matematicianul englez Ian Stewart dezvăluie în Dă oare Dumnezeu cu zarul? una dintre cele mai incitante aventuri ştiinţifice din ultimele decenii„Eu am petrecut mult timp în lumea reală a cercetării matematice Aş putea spune „Haideţi terminaţi cu jocurile astea copilăreşti cu acţiuni la bursă nu s decât născociri fără sens Ce aţi zice să demonstrăm nişte teoreme reale?? It's stunning and intriguing review of nonlinear systems chaos from countless real world perspectives Stewart's humorous and engaging writing style makes the book a pleasure He starts from simple mathematical euations and simple physical systems such as pendulums and turbulent water and routinely takes the idea out to cutting edge research or engineering possibilitiesNow I know what math textbooks and areas of study to proceed to and Stewart has given mea geometric ability to visualize necessary for success
