Space Time Play

Computer and video games are leaving the PC and conquering the arena of everyday life in the form of mobile applications—the result is new types of cities and architecture. How do these games alter our perception of real and virtual space? What can the designers of physical and digital worlds learn from one another?

Presenting the history of space-time physics, from Newton to Einstein, as a philosophical development DiSalle reflects our increasing understanding of the connections between ideas of space and time and our physical knowledge. He suggests that philosophy's greatest impact on physics has come about, less by the influence of philosophical hypotheses, than by the philosophical analysis of concepts of space, time and motion, and the roles they play in our assumptions about physical objects and physical measurements. This way of thinking leads to interpretations of the work of Newton and Einstein and the connections between them. It also offers ways of looking at old questions about a priori knowledge, the physical interpretation of mathematics, and the nature of conceptual change. Understanding Space-Time will interest readers in philosophy, history and philosophy of science, and physics, as well as readers interested in the relations between physics and philosophy.

Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein's field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

Travel to planets unknown in book two of the Space-Time graphic novel series from the author of the New York Times bestselling Jedi Academy books! Jide, Petra, and their intergalactic friends are back on the Potato (their orbiting classroom) for another out-of-this-world adventure. Their latest space mission brings them to the home planets of their schoolmates, where pranks must be avenged, new terrains must be explored, and the patience of Commander G must be tested! Buckle up! The next Space-Time series mission from New York Times bestselling author Jeffrey Brown is ready for blast off!

This excellent textbook offers a unique take on relativity theory, setting it in its historical context. Ideal for those interested in relativity and the history of physics, the book contains a complete account of special relativity that begins with the historical analysis of the reasons that led to a change in our view of space and time. Its aim is to foster a deep understanding of relativistic spacetime and its consequences for Dynamics.

The Journal of Irreproducible Results is the funniest thing to happen to science since Archimedes ran naked through the streets of Syracuse." --Discover Science humor magazine The Journal of Irreproducible Results has targeted "hypocrisy, arrogance, and ostentatious sesquipedalian circumlocution" since 1955. JIR editor Norman Sperling presents humorous and quirky tidbits relating to science, math, academia, bureaucracy, and witty word play. More than 250 entries ponder and pun the practical and peculiar. Consider OSHA's definition of the word "exit" as compared to Merriam Webster's: OSHA states, "Exit is the portion of a means of egress which is separated from all other spaces of the building or structure by construction or equipment as required in this subpart to provide a protected way to travel to exit discharge." Webster's defines "exit" as, "A way out of an enclosed place or space." If you've ever questioned the warning label on your hand drill that reads, "This product is not intended for use as a dental drill," or wonder what the "punishable by law" penalty is for snipping off that warning label on your pillow or mattress, then this book is for you.

The relationship between mind and reality is usually perceived as an event that takes place in reality and producing simultaneously an internal image in the mind. So it takes place twice, so to speak, and there is a one-to-one correspondence between the two events. Within this conception, matter is embedded in space and time, and can be designated as “container-principle”. This monograph emphasizes that the well-known philosopher Immanuel Kant denied this principle and he stated that reality is principally not recognizable to a human being, and modern biological evolution seems to lead exactly to Kant's point of view. Within the theory of evolution, man's image about reality in mind does not have to be complete and true in the sense of a precise reproduction, and it is relatively easy to recognize that even space and time should not be elements of reality outside. Within this conception, only a certain part of reality, which the human being needs for mastering life, is projected onto space and time, and we come to the so-called “projection principle”. Then, spacetime defines the window to reality, leading to a number of exciting and essential questions, some of which are discussed in this monograph.As is known, current physics is mainly based on the container-principle. But this monograph proposes that the projection principle is obviously more suitable and could help to solve open-ended questions as, for example, in connection with the nature of time, the particle-wave duality, the cosmological constant, etc. Regarding the statistical behavior of matter, Einstein's statement “God does not play dice” has to be seen in a new light, but also Feynman's general viewpoint on quantum theory that it cannot be understood by man. However, conventional quantum theory is obviously not a consistent framework as per the projection principle. The term “world equation” is critically probed in this monograph.
