In this book about science in daily life, Julien Bohdanowicz explains that physics can help us understand how waste products have poisoned our environment, but also that it can show us how to treat waste. He makes readers discover the laws of the conservation of energy, which can be summarised in the well-known adage: Nothing is lost, nothing is created, everything is transformed. Julien Bohdanowicz is an engineering student at the École Nationale Supérieure des Techniques Avancées.
What is perversion really about? What does a pervert seek? The world of perversions is not only a mirror world of physical pleasure, it also serves as a mechanism of power in a relationship which the pervert uses to impose his/her rule on another, by denying his/her existence. Does the pervert seek pleasure or power? Alberto Eiguer is a psychoanalyst specialising in family therapy.
