Book description

This book develops and applies an analytical approach to deriving the probability laws of science in general. It is called 'extreme physical information' or EPI. EPI is an expression of the imperfection of observation: Owing to random interaction of a subject with its observer and other possible disturbances, its measurement contains less Fisher information than does the subject per se. Moreover, the information loss is an extreme value. An EPI output may alternatively be viewed as the payoff of a zero-sum game of information acquisition between the observer and a 'demon' in subject space. EPI derives, Escher-like, the very probability law that gave rise to the measurement. In applications, EPI is used to derive both existing and new analytical relations governing probability laws of physics, genetics, cancer growth, ecology and economics. This unified approach will be fascinating to students and those who seek a new mathematical tool of research.

Reviews

‘… a stunningly clear interpretation of the laws of physics … Unlocking the fundamental laws is impressive enough, but if this one principle really is the key to all physics, it should do more than reproduce what physicists already know. It should also reveal the secrets of unsolved mysteries.’

Robert Matthews Source: New Scientist

‘The book has two attractive features: the frequent discussions in basic physical terms, and the candid way in which the author describes how he has developed his thoughts … I urge the readers of this review to take a good look at the book, which is well-written and certainly thought-provoking.’

‘This is a delightful and very well written postgraduate level text, which should be of interest to a wide audience including physicists and philosophers. It is a landmark book whose ideas will be discussed and hopefully will be further developed in the future, as it provides a brand new framework to interpret the laws of nature.‘
