Paperback. Condición: Like New. He believes in science, but only magic can help his mom. Twelve-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom abandoned him and his dad with no explanation. Finn clings to the concrete facts in his physics books--and to his best friend, Gabi--to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time. Finn's mom is trapped somewhere in the timeline, and she's left Finn a portal to find her. But to succeed, he'll have to put his trust in something bigger than logic. "This is an incredible book, no matter which time universe you're in. I couldn't put it down. One of my favorite debut novels of the year." --Erin Entrada Kelly, New York Times bestselling author and 2018 Newbery Medal winner.…

Hardback. Condición: Good. The volume contains new publications of five works by Einstein - his valuable book Relativity: The Special and the General Theory, written for a wider audience - and four articles, which nicely complement the issues discussed in the book.The selected works contain not only Einstein's own explanations of his revolutionary contributions to fundamental physics, but also give the readers, particularly his popular book, the unique chance to be exposed to Einstein's original thinking in action. Einstein's five works included in the volume are:1. Relativity: The Special and the General Theory. A Popular Exposition 2. What is the Theory of Relativity, written at the request of The London Times and published on November 28, 19193. Ether and the Theory of Relativity, An Address delivered on May 5th, 1920 in the University of Leyden4. Geometry and Experience, An expanded form of an Address to the Prussian Academy of Sciences in Berlin on January 27th, 19215. A Brief Outline of the Development of the Theory of Relativity, Nature volume 106, pages 782-784 (17 February 1921)One notable issue - the concept of relativistic mass - is not discussed in Einstein's five works republished in the volume. Although he wrote in his popular book (included here, p. 36) the inertial mass of a body is not a constant, Einstein did not discuss the concept of relativistic mass (i.e., the relativistic increase of the mass of a body as its velocity increases), which he silently abandoned after using it in his 1905 paper, where he defined longitudinal mass and transverse mass. As Einstein's unclear view of the relativistic mass might have provided some encouragement for what has probably been the most vigorous campaign ever waged against the concept of relativistic mass, an Appendix On Relativistic Mass is included in this volume to address that unprecedented campaign and to help the readers make their own decision on the concept of relativistic mass.…
