Special Relativity Paradox Understanding Relativity: A Simplified Approach to Einstein's Theories by Leo Sartori, Nonspecialists with no prior knowledge of physics and only reasonable proficiency with algebra can now understand Einstein's special theory of relativity. Effectively diagrammed and with an emphasis on logical structure, Leo Sartori's rigorous but simple presentation will guide interested readers through concepts of relative time and relative space. Sartori covers general relativity and cosmology, but focuses on Einstein's theory. He tracks its history and implications. He explores illuminating paradoxes, including the famous twin paradox, the "pole-in-the-barn" paradox, and the Loedel diagram, which is an accessible, graphic approach to relativity. Students of the history and philosophy of science will welcome this concise introduction to the central concept of modern physics.
What Is Relativity? by L. D. Landau, A pair of eminent Russian theoretical physicists offer a captivating view of the paradoxes inherent to the special theory of relativity. Written in a simple, straightforward fashion, the text uses familiar objects (trains, rulers, and clocks, for example) to illuminate the more subtle and elusive aspects of relativity. Contents: 1. Familiar Examples of Relativity. 2. Space Is Relative. 3. The Tragedy of Light. 4. Time Proves to Be Relative. 5. Clocks and Rulers Play Tricks. 6. Work Changes Mass. 7. Summing Up. Index. Unabridged republication of the edition published by Basic Books, Inc., New York, 1959. 23 black-and-white illustrations.
Transition from special relativity to general relativity - The basic structure of general relativity, including the geodesic equation and Einstein field equation, can be obtained from special relativity by examining the dynamics of a particle in a circular orbit about the earth. Twin paradox - The twin paradox, sometimes called the "clock paradox", stems from Paul Langevin's 1911 thought experiment in special relativity: one of two twin brothers, undertakes a long space journey with a high-speed rocket at almost the speed of light, while the other twin remains on Earth. When the traveler returns to Earth, he is younger than the twin who stayed put. Ladder paradox - The ladder paradox or (barn-pole paradox) is a thought experiment in special relativity. If a long ladder travels horizontally at almost the speed of light, it will undergo a length contraction and will therefore fit into a garage which is shorter than the ladder's length at rest. EPR paradox - In quantum mechanics, the EPR paradox (Einstein-Podolsky-Rosen) is a thought experiment that demonstrates that the result of a measurement performed on one part of a quantum system can have an instantaneous effect on the result of a measurement performed on another part, regardless of the distance separating the two parts. This runs counter to the intuition of special relativity, which states that information cannot be transmitted faster than the speed of light. specialrelativityparadox |
