        Science of Illusion

        by Mohamed Yahia

        How were people forced to believe in the rotation of planets around the Sun? What if Newton's theory was a mathematical miracle and a physical disaster? Do you know anything about relativity and the texture of spacetime? How did the battle between relativity and quantum take place, and how did attempts to reconcile them take place? Do you consider INTERSTELLAR a pure fantasy? Do you see in the series DARK unreasonable oddities? What if these dramas were based on some theories of modern physics?! This book tells you the story of science from birth, the attempts to depart science from imaginary myths and superstitions in explaining phenomena and the mechanism of action of the universe, and how it ended up authorizing to nature facts stranger than the imagination from which it was fleeing! Time may stop, the past, the present and the future are all present, your outlook is what creates reality around you, gravity may be a means of communication between us and aliens, and you and I may be just a three-dimensional projection of a caricature story with only two dimensions! This is the tale of science, preceded by imagination, preceded by it.

        De sublieme eenvoud van relativiteit

        Een visuele inleiding

        by Sander Bais

        Bais wrote a cute pictorial monograph that smoothly takes you to the very heart of the theory that shook the foundations of science a century ago. Einstein’s 1905 papers on special relativity marked a turning point in our understanding of such fundamental notions a space, time, mass and energy. In an elegant sequence of easy to follow steps through a splendid series of spacetime diagrams Sander Bais gives you the thrill of discovering Einstein’s sublime but extremely counter intuitive reality yourself. The chapters cover subjects like , the postulates, simultaneity, causality, contractions and dilations, and energy and momentum. Discover in a pictorial way why moving clocks run slow, why things cannot move faster then the speed of light, or why mass and energy are equivalent… A delightful journey for the curious mind, the critical student, and the teacher who wants to inspire, but also for all those who want to recapture this beautiful body of knowledge. This book is not as much a philosophical or historical reflection on special relativity, as a manual that with a few words brings you the essential contents of this unique theory. A guided tour full of thought provoking riddles, paradoxes and brainteasers that might keep you awake, fortunately their many back-of- the-envelope resolutions are also included. This book is as close to a do-it-yourself relativity kit as you can get. The author nicely exploits the fact that one image can say a lot more than a full page of algebra, and where algebra is hard to remember some of Bais’ diagrams are hard to forget.
