The present is the time that is perceived directly, not as a recollection or a speculation. For other uses see Time (disambiguation Time is a component of a measuring system used to sequence events to compare the durations of In Psychology and the Cognitive sciences perception is the process of attaining awareness or understanding of sensory Information. It is often considered as a hyperplane in space-time, often called now, but it may also be viewed as a duration (see specious present). A hyperplane is a concept in Geometry. It is a higher-dimensional generalization of the concepts of a line in Euclidean plane geometry and a SpaceTime is a patent-pending three dimensional graphical user interface that allows end users to search their content such as Google Google Images Yahoo! YouTube eBay Amazon and RSS The specious present is the Time duration wherein one's Perceptions are considered to be in the present.
When comparing time in places separated by great distances, the notion of present becomes unclear. For example, we visually perceive stars to be where they were when the light now reaching our eyes was emitted, because even though light travels at approximately 3 x 108 m/s it takes many years to reach us from distant sources. A star is a massive luminous ball of plasma. The nearest star to Earth is the Sun, which is the source of most of the Energy on Earth Light, or visible light, is Electromagnetic radiation of a Wavelength that is visible to the Human eye (about 400–700
When used in the term "Before Present" (BP), as used in expressing ages or dates determined by radiocarbon dating, "Present" is defined as AD 1950. Before Present (BP years are a time scale used in Archaeology, Geology, and other scientific disciplines to specify when events in the past occurred Radiocarbon dating is a Radiometric dating method that uses the naturally occurring Radioisotope Carbon-14 (14C to determine the age of Year 1950 ( MCML) was a Common year starting on Sunday (link will display the full calendar of the Gregorian calendar.
Modern physics has not yet been able to explain what we normally understand by 'now'. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Furthermore, there is no demonstrable reason why time should move in any one particular direction. For other uses see Time (disambiguation Time is a component of a measuring system used to sequence events to compare the durations of This has led to the conclusion that the idea of a present is illusory and does not reflect the true nature of reality. Reality, in everyday usage means "the state of things as they actually exist" The notion of "now" may be better understood as an unrealistic concept that has evolved in humans and animals to give us an understanding of reality useful only to the extent necessary for survival. The term "concept" is traced back to 1554–60 ( l conceptum - something conceived but what is today termed "the classical theory of concepts" is the theory of Aristotle eVolution is the third Album by eLDee, it was due to be released in 2008

The present according to Special Relativity
It follows from Albert Einstein's Special Theory of Relativity that there is no such thing as absolute simultaneity. Albert Einstein ( German: ˈalbɐt ˈaɪ̯nʃtaɪ̯n; English: ˈælbɝt ˈaɪnstaɪn (14 March 1879 – 18 April 1955 was a German -born theoretical Special relativity (SR (also known as the special theory of relativity or STR) is the Physical theory of Measurement in Inertial The relativity of simultaneity is the concept that simultaneity is not absolute but dependent on the observer Therefore, if we define "present" to be the collection of events that are simultaneous with a given event, then "present" takes different meanings for different observers. Instead, with "present" defined as the events perceived directly, not as a recollection or a speculation, for a given observer "present" takes the form of the observer's past light cone. In Psychology and the Cognitive sciences perception is the process of attaining awareness or understanding of sensory Information. In Special relativity, a light cone (or null cone) is the pattern describing the temporal evolution of a flash of Light in Minkowski spacetime The light cone of a given event is objectively defined as the collection of events in causal relationship to that event, but each event has a different associated light cone. Causality describes the relationship between Causes and Effects is fundamental to all natural Science, especially Physics, and has a basis in One has to conclude that in relativistic models of physics there is no place for "the present" as an absolute element of reality. Einstein phrased this as: "People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion". [1]
A philosophical problem
"The present" also raises another difficult question: "How is it that all sentient beings experience "now" at the same time?" There is no logical reason why this should be the case and no easy answer to the question. For example, say somebody named John is experiencing a great deal of pain. John's friend Fred takes pity on John because of John's situation. The problem is: is it logical for Fred to feel bad for John at present, when there is no way to prove that both John and Fred experience the same temporal existence? (See also Solipsism and Philosophy of mind. Temporal Parts are used in contemporary Metaphysics in the debate over persistence of material objects Solipsism ( Latin: solus, alone + ipse, self is the philosophical idea that "My mind is the only thing that I know exists Philosophy of mind is the branch of Philosophy that studies the nature of the Mind, Mental events Mental functions mental properties )
The present in Buddhism
Buddhism and many of its associated philosophies emphasize the importance of living in the present moment — being fully aware of what is happening, and not dwelling on the past or worrying about the future. Buddhism is a family of beliefs and practices Philosophy is the study of general problems concerning matters such as existence knowledge truth beauty justice validity mind and language PAST (short for Polska Akcyjna Spółka Telefoniczna, Polish Telephone Joint-stock Company) was a Polish telephone operator in the period between World War I The future is commonly understood to contain all events that have yet to occur This does not mean that they encourage hedonism, but merely that through constantly focusing on one's current position in space and time (rather than future considerations, or past reminiscence) will aid one in relieving suffering. Hedonism is the Philosophy that Pleasure is of ultimate importance, the most important pursuit A number of meditative techniques aim to help the practicer live in the present moment. Meditation is a mental discipline by which one attempts to get beyond the conditioned "thinking" mind into a deeper state of relaxation or awareness
Christianity and eternity
God is viewed as being outside of time and from the divine perspective past, present and future are actualised in the now of eternity. God is the principal or sole Deity in Religions and other belief systems that worship one deity. While in the popular mind eternity often simply means existing for a limitless amount of Time, many have used it to refer to a timeless existence altogether outside of Saint Thomas Aquinas used the image of a watchman, representing God, standing on a height looking down on a valley where past present and future, represented by the individuals and their actions strung out along its length, are all visible simultaneously to God.
Eternal now
Eckhart Tolle, in his book The Power of Now (1997), argues that only the present moment exists. Eckhart Tolle (born February 16 1948) is a German / Canadian spiritual teacher motivational speaker and writer The Power of Now A Guide to Spiritual Enlightenment is a Self help book by Eckhart Tolle. Tolle argues that time is an illusion, and that the past exists only as a memory stored in the mind, while the future is imagined, a projection of the mind. [2]
Quotes
There's no present. There's only the immediate future and the recent past.
– George Carlin
You shouldn't chase after the past or place expectations on the future. What is past is left behind. The future is as yet unreached. Whatever quality is present you clearly see right there, right there.
What we perceive as present is the vivid fringe of memory tinged with anticipation. Siddhārtha Gautama ( Sanskrit; Pali: Siddhattha Gotama) was a spiritual Teacher from Ancient India and the founder
– Alfred North Whitehead, The Concept of Nature[4]
There's no time like the present. Alfred North Whitehead, OM ( February 15 1861, Ramsgate, Kent, England &ndash December 30 1947,
