What is the nature of the 'laws' that Marx and Engels sought to formulate for the development of capitalism? How to understand and judge Engels's attempt to formulate a general philosophy and worldview? These are the questions highlighted in this magnificent work that situates Marx and Engels's writing against the background of the entire nineteenth-century world of scientific problems, from physics to historiography. One of the major contributions to scholarship on Marx, Engels and nineteenth-century science, Liedman's work is here presented in English translation and with a new preface by the author.

This is an account of the author's investigation, on behalf of the Canadian government, into the life and ideas of the eccentric genius Nikola Tesla. This is a completely revised and redesigned edition, with a new introduction by the former head of the Tesla Museum, a new chapter and a selection of photographs of Tesla and his work in search of the holy grail of electricity - the transmission of power without loss. As a student in Prague in the 1870s, Tesla "saw" the electric induction motor and patented his discovery, -the first of many inventions whose plans seem to have come to him fully fledged. He worked for the Edison company in Paris before emigrating to the US and battling with Thomas Edison himself to ensure that alternating, rather than direct current, became the standard. He sold his patent in the induction motor for $1 million dollars to George Westinghouse, who used this system for the Niagara Falls Power Project. Moving to Colorado Springs, Tesla worked on resonance, building enormous oscillating towers in experiments which still intrigue today. In later life Tesla became a recluse, bombarding newspapers with eccentric claims, including energy transmissions to other planets. Though he died alone and virtually forgotten, rumours gradually grew that Tesla had made further remarkable discoveries. In an attempt to replicate his experiments, people still build Tesla towers and puzzle over the possible link with low-frequency broadcasts which can supposedly disrupt the weather and affect the human mind.

Estimation of Time since Death in Australian Conditions collates data about decomposed bodies found in the eastern states of Australia from the years 2000 to 2010. The book takes into account that over 70% of decomposed bodies were found within 14 days. From standard autopsy reports, a quantitative method of assessing the degree of decomposition in four specific body organs and the total appearance of the body was collated into a total body score (tbs). The mathematical models on how to estimate time since death in the eastern states of Australia are covered in this valuable resource.
