In this sequel to The Fourth Dimension, Volume 1, Dr. David Yonggi Cho shows how you can develop the dynamic faith and true communion with God which overcome spiritual obstacles and surpass barriers.

A book from the stand-up mathematician that makes math fun again! Math is boring, says the mathematician and comedian Matt Parker. Part of the problem may be the way the subject is taught, but it's also true that we all, to a greater or lesser extent, find math difficult and counterintuitive. This counterintuitiveness is actually part of the point, argues Parker: the extraordinary thing about math is that it allows us to access logic and ideas beyond what our brains can instinctively do—through its logical tools we are able to reach beyond our innate abilities and grasp more and more abstract concepts. In the absorbing and exhilarating Things to Make and Do in the Fourth Dimension, Parker sets out to convince his readers to revisit the very math that put them off the subject as fourteen-year-olds. Starting with the foundations of math familiar from school (numbers, geometry, and algebra), he reveals how it is possible to climb all the way up to the topology and to four-dimensional shapes, and from there to infinity—and slightly beyond. Both playful and sophisticated, Things to Make and Do in the Fourth Dimension is filled with captivating games and puzzles, a buffet of optional hands-on activities that entices us to take pleasure in math that is normally only available to those studying at a university level. Things to Make and Do in the Fourth Dimension invites us to re-learn much of what we missed in school and, this time, to be utterly enthralled by it.

In a world with no power, chaos soon descends. A powerful look at the disintegration of society in the wake of a massive and mysterious outage that has knocked out all modern amenities. Fifteen-year-old Emma has moved house with her ex-Marine mother and younger brother. It's a brand-new condo building, which explains the semi-regular power outages, as workers complete the units around them. So Emma isn't particularly concerned when the latest blackout hits just as they are preparing to leave town on a long weekend camping trip. But then the car won't start, and their cellphones appear dead -- and all the cars outside their building seem to be stalled in a long traffic jam ... In the midst of what appears to be a massive power outage, with their camping gear packed and ready, Emma and her family canoe over to the islands, just offshore, to wait it out. But while they land on an isolated island, with a relatively hidden site, they are far from safe, as people become increasingly desperate to find food and shelter. And as the days pass, and the power remains out, the threat of violence becomes all too real.

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.

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.
