Mit der Übersetzung des platonischen Dialogs "Timaios" wollte Cicero den Römern einen weiteren Zugang zur Philosophie eröffnen. Da der lateinischen Sprache wichtige Wörter fehlten, musste er sich dabei auch als Sprachschöpfer betätigen. Das Gespräch kreist um die Erschaffung des Weltkörpers und der Weltseele, die Erschaffung der Zeit und der Planeten, aber auch musiktheoretische Überlegungen (zu den Intervallen), Gedanken über die Seele und die Seelenwanderung sowie die menschliche Wahrnehmung spielen eine Rolle. Der Dialog schließt mit einem Lob der Philosophie, "dem wünschenswertesten und hervorragendsten Gut, das dem Menschengeschlecht von den Göttern als Gnadengabe zugestanden worden ist".

Galilée mesure la chute des corps, Harvey démontre que le sang circule, Newton décompose la lumière, Lavoisier comprend le phénomène de la combustion, Galvani met en évidence le rapport entre l’électricité et le système nerveux, Faraday invente les bases du moteur électrique, Joule démontre que chaleur et travail sont liés, Michelson mesure la vitesse de la lumière, Pavlov découvre les lois de l’acquisition des réflexes conditionnés, Millikan mesure la charge de l’électron. Avec le récit de ces dix expériences scientifiques fondatrices, menées avec une élégance simple qu’elles méritent d’être qualifiées de belles, George Johnson fait revivre une époque où la science était faite sur le terrain, par des hommes qui se confrontaient, seuls, à l’inconnu.

The scientific method is one of the most basic and essential concepts across the sciences, ensuring that investigations are carried out with precision and thoroughness. The scientific method is often taught as a step-by-step approach, but real examples from history are not always given. This book teaches the basic modes of scientific thought, not by philosophical generalizations, but by illustrating in detail how great scientists from across the sciences solved problems using scientific reason. Examples include Christopher Columbus, Joseph Priestly, Antoine Lavoisier, Michael Faraday, Wilhelm Röntgen, Max Planck, Albert Einstein, and Niels Bohr. Written by a successful research physicist who has engaged in many studies and years of research, all in the attempt to extract the secrets of nature, this book captures the excitement and joy of research. The process of scientific discovery is as delightfully absorbing, as complex, and as profoundly human as falling in love. It can be a roller coaster ride of despairing valleys and exhilarating highs. This book sketches the powerful reasoning which led to many different discoveries, but also celebrates the "ah-ha moments" experienced by each scientist, letting readers share the thrilling instant when each scientist reached the critical revelation in his research. Places the scientific method in context using historical examplesSuitable for both scientists and non-scientists looking to better understand scientific reasoningWritten in an engaging style with clear illustrations and referencing.
