**BOOK SUMMARY :**

The point of departure of michael strevenss book is the fact that people seem able to predict statistical distributions over evolved states of dynamical systems whose individual outcomes are highly sensitive to initial conditions systems like roulette wheels tossed coins drawings from urns shuffled cards and more exotically molecular velocities and to do so independently of any tychomancy meaning the divination of chances presents a set of rules for inferring the physical probabilities of outcomes from the causal or dynamic properties of the systems that produce them probabilities revealed by the rules are wide ranging they include the probability of getting a 5 on a die roll the probability distributions found in statistical physics and the probabilities get this from a library tychomancy inferring probability from causal structure michael strevens main description tychomancy meaning the divination of chances presents a set of rules for inferring the physical probabilities of outcomes from the causal or dynamic properties of the systems get this from a library tychomancy inferring probability from causal structure michael strevens michael strevens makes three claims about rules for inferring physical probability they are reliable they constitute a key part of the physical intuition that allows us to navigate the world safely prices in us apply to orders placed in the americas only prices in gbp apply to orders placed in great britain only prices in represent the retail prices valid in germany unless otherwise indicated
