Four Dimensional Time

Einstein shocked the world by revealing that time can be different for different observers. This book offers a possible explanation of why it is so. It offers a never-attempted-before approach to understand the secret of time. As we all know, there is an intimate relationship between time and age of objects. But what is this relationship? The author dives deep into the possible relationships between time and age of objects- animate or inanimate- and, in turn, emerges with a novel concept of time- time is a measurement of age. The book proposes that time is acquired by age, not required for it; and thus, time is an acquired property of objects. The author also proposes that just as length, width and height are the measurements of physical extensions of objects (their three spatial dimensions) and not any independent entities; time too, being the measurement of their age, is not independent of objects. In this sense, time seems to be the fourth dimension of objects instead of space. The book attempts to justify its hypothesis by testing its compatibility with Theory of Relativity. Also discussed is the meaning of the so called passage of time and the arrow of time on the basis of the model of time proposed here. The meaning of the much debated concept of time-travel is thoroughly discussed here and it is proposed that this concept, in the sense that we usually take, is a myth. Even if you can manage to reach your future by overcoming all technological limitations (as we all know, theory of relativity allows it), all your friends will be there with you, witnessing the same future. The only difference will be- your clocks will not agree with those of your friends.

Space, Time and Einstein by J. B. KennedyThis book is a threefold invitation to the philosophy of space andtime. It introduces - gently and simply - the new, revolutionary ideasof Einstein. It introduces the concepts and arguments of philosophers,both ancient and modern, which have proved of lasting value. Finally,it introduces the most recent discoveries and the debates raging now,in philosophy and physics, and points out how future developmentsmay unfold.The text does aim to teach one skill. Careful thinking is at the coreof our conception of philosophy. Now that many nations havereorganized themselves as democracies, which depend so much onreasoned debate and persuasion, careful thinking has become afoundation of our social and political lives as well. But clear thinkingis an art: it requires patience, practice and cultivation. This text doesnot teach or use formal logic, but it pays great attention to the careful analysis and interpretation of ideas. It slows down to dissect moment-ous claims and seeks out the hidden assumptions underlying the greatarguments of the past. It aims throughout to show how the analysis ofarguments deepens our appreciation of philosophy, and points theway towards future progress.This is a conservative text in the sense that it covers the standardtopics, outlines mainstream debates and introduces the views of someleading contemporary philosophers. Unusually, from the outset, itemphasizes the controversy between Einstein and Lorentz over theinterpretation of relativity (following essays by J. S. Bell and the moremathematical text by D. Bohm), which is now again a hot topic ofdebate. For accessibility, I have edited the quotations to conform to auniform terminology, ruthlessly preferred concrete over technicalterms (e.g. "rulers and clocks" rather than "reference frames") andpostponed all spacetime diagrams to an appendix. In general, I havefavoured bold, plausible claims and used the guide for further readingin Appendix E to point toward more advanced and nuanced litera-ture. This approach has worked well in courses I have taught atStanford University and the University of Notre Dame in the US andthe University of Manchester in the UK. There was no room forchapters on debates over space and time in the feminist philosophy ofscience and in art history, but some reference.

One of the most talented contemporary authors of cutting-edge math and science books conducts a fascinating tour of a higher reality, the fourth dimension. Includes problems, puzzles, and 200 drawings. "Informative and mind-dazzling." — Martin Gardner.

What a wonderful book! I strongly recommend this book to anyone, especially graduate students, interested in getting a sense of 4-manifolds. —MAA Reviews The book gives an excellent overview of 4-manifolds, with many figures and historical notes. Graduate students, nonexperts, and experts alike will enjoy browsing through it. — Robion C. Kirby, University of California, Berkeley This book offers a panorama of the topology of simply connected smooth manifolds of dimension four. Dimension four is unlike any other dimension; it is large enough to have room for wild things to happen, but small enough so that there is no room to undo the wildness. For example, only manifolds of dimension four can exhibit infinitely many distinct smooth structures. Indeed, their topology remains the least understood today. To put things in context, the book starts with a survey of higher dimensions and of topological 4-manifolds. In the second part, the main invariant of a 4-manifold—the intersection form—and its interaction with the topology of the manifold are investigated. In the third part, as an important source of examples, complex surfaces are reviewed. In the final fourth part of the book, gauge theory is presented; this differential-geometric method has brought to light how unwieldy smooth 4-manifolds truly are, and while bringing new insights, has raised more questions than answers. The structure of the book is modular, organized into a main track of about two hundred pages, augmented by extensive notes at the end of each chapter, where many extra details, proofs and developments are presented. To help the reader, the text is peppered with over 250 illustrations and has an extensive index.

You are a four-dimensional human. Each of us exists in three-dimensional, physical space. But, as a constellation of everyday digital phenomena rewires our lives, we are increasingly coaxed from the containment of our predigital selves into a wonderful and eerie fourth dimension, a world of ceaseless communication, instant information, and global connection. Our portals to this new world have been wedged open, and the silhouette of a figure is slowly taking shape. But what does it feel like to be four-dimensional? How do digital technologies influence the rhythms of our thoughts, the style and tilt of our consciousness? What new sensitivities and sensibilities are emerging with our exposure to the delights, sorrows, and anxieties of a networked world? And how do we live in public with these recoded private lives? Laurence Scott—hailed as a “New Generation Thinker” by the Arts and Humanities Research Council and the BBC—shows how this four-dimensional life is dramatically changing us by redefining our social lives and extending the limits of our presence in the world. Blending tech-philosophy with insights on everything from Seinfeld to the fall of Gaddafi, Scott stands with a rising generation of social critics hoping to understand our new reality. His virtuosic debut is a revelatory and original exploration of life in the digital age.

A detailed description of what the fourth dimension would be like.

Exposition of fourth dimension, concepts of relativity as Flatland characters continue adventures. Topics include curved space time as a higher dimension, special relativity, and shape of space-time. Includes 141 illustrations.

Mathematics made mouth-watering. Things to Make and Do in the Fourth Dimension is an alternative math class. How can math help you choose a second-hand car? Why is a text message like a Sudoku? How much fun can you have with a barcode? Matt Parker explains that math is difficult because it's one of the few subjects that requires us to train our brains to think in an entirely new way, and to confront things with no direct analogy in everyday life--imaginary numbers, snowflakes that only exist in 196884 dimensions, and objects beyond infinity--and shows us why it's worth the effort. Starting with basic arithmetic and geometry, Things To Make and Do teaches us the math we never got to enjoy at school. Each chapter is structured around activities and thought experiments: we are invited to make a calculator out of dominoes, find out why wrapping oranges in plastic wrap is a good way to learn about higher dimensions, and discover what soap bubbles have to teach us about calculus. A series of incremental and hugely entertaining steps take us all the way from simple algebra to the most exotic and fascinating ideas in mathematics: Klein bottles, higher dimensional topology and the many different species of infinity, via unimaginably small pizza slices, Mobius strips and a thorough examination of The Sausage Conjecture. This lively, funny, and deeply intelligent book teaches math in a fun, interactive manner rather than by rote learning and exercises. You'll not look at the number 37 the same way again. And you just might take part in Mobius strip craftwork.
