Well, we all know that Paris is romantic and enticing - as reflected in our book "Paris - Why So Many Call This City Mon Amour," but Paris is also a major city of education and research, and for this reason is called The City of Light. Examples of research activities include improving single-cell analysis by applying mathematical statistics, a new mathematical theory showing that the concept of a 'species' does not apply to all creatures, and the infinity of time and space (the axioms are in our book "Axioms, aphorisms and quotations - with examples and explanations"). It counts also that Paris is the most lit city in the world, with splendid Art Nouveau lamps, and in 1828 was one of the first cities to adopt gas street lighting. In what Palais l'Assemblee Nationale is located? Where Atelier Brancusi is placed? Where the highest point in Paris is? When l'Academie francaise and l'Academie des sciences were established? All these questions, and hundreds more, have their answers in this book. The over 200 photos, taken in October 2013, with their comprehensive and eye-catching explanations, indubitably show why this city is La Ville-Lumiere. Paris is very distinctive and any reader, no matter from what place of the world, will positively find, in this book of general interest, numerous mesmerizing and treasured images and facts."
