Does time really flow  or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries  or is it infinite? Is change really possible? Could space and time exist in the absence of any objects or events? What  in the end  are space and time? Do they really exist  or are they simply the constructions of our minds? Robin Le Poidevin provides a clear  witty  and stimulating introduction to these deep questions and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time  but he also gives us the basis to think about these problems independently  avoiding large amounts of jargon and technicality. His book is an invitation to think philosophically rather than a sustained argument for particular conclusions  but Le Poidevin does advance and defend a number of controversial views. He argues  for example  that time does not actually flow  that it is possible for space and time to be both finite and yet be without boundaries  and that causation is the key to an understanding of one of the deepest mysteries of time: its direction. Drawing on a variety of vivid examples from science  history  and literature  Travels in Four Dimensions brings to life some of the most profound questions imaginable.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":44983957913653,"sku":"ByrdShop_0198752547","price":43.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780198752547.jpg?v=1770815887","url":"https:\/\/atxbooks.com\/products\/travels-in-four-dimensions-the-enigmas-of-space-and-time","provider":"ATX Books","version":"1.0","type":"link"}
