About Time (book)
''About Time: Einstein's Unfinished Revolution'' (), published in 1995, is the second book written by Paul Davies, regarding the subject of time. His first book on time was his ''The Physics of Time Asymmetry'' (1977)(). The intended audience is the general public, rather than science academics. ''About Time'' explores selected mysteries of spacetime, following on from Albert Einstein's theory of relativity, which Davies believes does not fully explain time as humans experience it. The author explains The book delves into the nature of metaphysics, time, motion and gravity, covering a wide range of aspects surrounding the current cosmological debate, across 283 pages in great detail. It includes an index, a bibliography, and numerous diagrams.

Diagram
A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word ''graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term " illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links. In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, represen ...

Physics Books
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (. ...

Science Books
A science book is a work of nonfiction, usually written by a scientist, researcher, or professor like Stephen Hawking (''A Brief History of Time''), or sometimes by a non-scientist such as Bill Bryson ('' A Short History of Nearly Everything''). Usually these books are written for a wide audience presumed to have a general education rather than a specifically scientific training, as opposed to the very narrow audience that a scientific paper would have, and are therefore referred to as popular science. As such, they require considerable talent on the part of the author to sufficiently explain difficult topics to people who are totally new to the subject, and a good blend of storytelling and technical writing. In the UK, the Royal Society Prizes for Science Books are considered to be the most prestigious awards for science writing. In the US, the National Book Awards briefly had a category for science writing in the 1960s, but now they just have the broad categories of fiction ...

How To Build A Time Machine
''How to Build a Time Machine'' by Paul Davies is a 2002 physics book that discusses the possibilities of time travel. It was published by Penguin Books. In this book, Davies discusses why time is relative, how this relates to time travel, and then lays out a "blueprint" for a real time machine. This is explored whilst also discussing paradoxes which allow a more constructive approach. It is a realistic, albeit fantastical, book.

The Mind Of God
''The Mind of God'' is a 1992 non-fiction book by Paul Davies. Subtitled ''The Scientific Basis for a Rational World'', it is a whirlwind tour and explanation of theories, both physical and metaphysical, regarding ultimate causes. Its title comes from a quotation from Stephen Hawking: "If we do discover a theory of everything...it would be the ultimate triumph of human reason—for then we would truly know the mind of God." In the preface, Davies explains that he has been interested in ultimate causes since childhood, having annoyed his parents with unending "why's" about everything, with each answer demanding another "why," and usually ending with the reply, "Because God made it that way, and ''that's that!''" In the book proper, Davies briefly explores: the nature of reason, belief, and metaphysics; theories of the origin of the universe; the laws of nature; the relationship of mathematics to physics; a few arguments for the existence of God; the possibility that the un ...

Sense Of Time
The study of time perception or chronoception is a field within psychology, cognitive linguistics and neuroscience that refers to the subjective experience, or sense, of time, which is measured by someone's own perception of the duration of the indefinite and unfolding of events. The perceived time interval between two successive events is referred to as perceived duration. Though directly experiencing or understanding another person's perception of time is not possible, perception can be objectively studied and inferred through a number of scientific experiments. Some temporal illusions help to expose the underlying neural mechanisms of time perception. Pioneering work, emphasizing species-specific differences, was conducted by Karl Ernst von Baer. Theories Time perception is typically categorized in three distinct ranges, because different ranges of duration are processed in different areas of the brain: * Sub-second timing or millisecond timing * Interval timing or seconds-t ...

Basic Introduction To The Mathematics Of Curved Spacetime
The mathematics of general relativity is complex. In Newton's theories of motion, an object's length and the rate at which time passes remain constant while the object accelerates, meaning that many problems in Newtonian mechanics may be solved by algebra alone. In relativity, however, an object's length and the rate at which time passes both change appreciably as the object's speed approaches the speed of light, meaning that more variables and more complicated mathematics are required to calculate the object's motion. As a result, relativity requires the use of concepts such as vectors, tensors, pseudotensors and curvilinear coordinates. For an introduction based on the example of particles following circular orbits about a large mass, nonrelativistic and relativistic treatments are given in, respectively, Newtonian motivations for general relativity and Theoretical motivation for general relativity. Vectors and tensors Vectors In mathematics, physics, and engineering, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibliography
Bibliography (from and ), as a discipline, is traditionally the academic study of books as physical, cultural objects; in this sense, it is also known as bibliology (from ). English author and bibliographer John Carter describes ''bibliography'' as a word having two senses: one, a list of books for further study or of works consulted by an author (or enumerative bibliography); the other one, applicable for collectors, is "the study of books as physical objects" and "the systematic description of books as objects" (or descriptive bibliography). Etymology The word was used by Greek writers in the first three centuries CE to mean the copying of books by hand. In the 12th century, the word started being used for "the intellectual activity of composing books." The 17th century then saw the emergence of the modern meaning, that of description of books. Currently, the field of bibliography has expanded to include studies that consider the book as a material object. Bibliography, in ...

Time
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is addre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Index (publishing)
An index (plural: usually indexes, more rarely indices; see below) is a list of words or phrases ('headings') and associated pointers ('locators') to where useful material relating to that heading can be found in a document or collection of documents. Examples are an index in the back matter of a book and an index that serves as a library catalog. An index differs from a word index, or ''concordance'', in focusing on the subject of the text rather than the exact words in a text, and it differs from a table of contents because the index is ordered by subject, regardless of whether it is early or late in the book, while the listed items in a table of contents is placed in the same order as the book. In a traditional ''back-of-the-book index'', the headings will include names of people, places, events, and concepts selected as being relevant and of interest to a possible reader of the book. The indexer performing the selection may be the author, the editor, or a professional inde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
