Devising and performing a scientific experiment is an art, and it is common to hear scientists talk about the 'beauty' of an experiment. What does this mean in chemistry, the experimental science par excellence? And what are the most beautiful chemical experiments of all time? This book offers ten suggestions for where beauty might reside in experimental chemistry. In some cases the beauty lies in the clarity of conception; sometimes it is a feature of the instrumental design. But for chemistry, there can also be a unique beauty in the way atoms are put together to make new molecules, substanc

This illustrated history of experimental science is more than just a celebration of the ingenuity that scientists and natural philosophers have used throughout the ages to study-and to change-the world. Here we see in intricate detail experiments that have, in some way or another, exhibited elegance and beauty: in their design, their conception, and their execution. Celebrated science writer Philip Ball invites readers to marvel at and admire the craftsmanship of scientific instruments and apparatus on display, from the earliest microscopes to the giant particle colliders of today. With Ball as our expert guide, we are encouraged to think carefully about what experiments are, what they mean, and how they are used. Ranging across millennia and geographies, Beautiful Experiments demonstrates why "experiment" remains a contested notion in science, while also exploring how we came to understand the way the world functions, what it contains, and where the pursuit of that understanding has brought us today.

Nos smartphones sont de véritables concentrés de capteurs technologiques : accéléromètres, magnétomètres, capteur de pression, de luminosité... qu'il est possible de détourner de leurs fonctions d'origine, afin de mener de véritables expériences scientifiques. Votre smartphone devient alors un laboratoire portatif pour expérimenter n'importe où et quand vous voulez. Après une description des différents capteurs d'un smartphone, cet ouvrage explique comment les utiliser pour tester les grands principes de la physique en mécanique, en acoustique et en optique. Grâce à l'utilisation d'applications simples et gratuites, il est ainsi possible de mesurer la vitesse du son, de peser la masse de la Terre, de voir et mesurer la taille des cellules, d'étudier le transit d'exoplanètes... Chaque expérience s'accompagne de rappels théoriques (niveau L1/L2) permettant au lecteur d'approfondir sa compréhension des phénomènes observés.
