You are here: BBC Space Exploration TIME TRAVEL Shaping the Future by Neil Johnson The idea of travelling forward into the future or back into the past has always fascinated science fiction writers. The 'grandfather paradox' is the argument many people use to suggest that time travel is impossible. What if you went back in time and prevented your grandfather from meeting your grandmother so that your mother was never born? Then you would never have been born... and so on. Until very recently such arguments led most scientists to believe that time travel could never exist outside science fiction. But amazingly, some interpretations of the weirdness of the quantum world now suggest that time travel is possible - at least in theory. Gravity and black holes Einstein's theory of relativity brought space and time together in a single, four-dimensional arrangement that he called spacetime. We know that we can travel forwards, backwards and sideways in space, so why not forwards and backwards in time?

103. New Quantum Theory Separates Gravitational And Inertial Mass - Technology Review Jun 14, 2010 But physicists have so far been unable to use quantum theory as a lever to tease apart the behaviour of inertial and gravitational mass. http://www.technologyreview.com/blog/arxiv/25331/

Newsletters New Quantum Theory Separates Gravitational and Inertial Mass kfc 06/14/2010 174 Comments The equivalence principle is one of the corner stones of general relativity. Now physicists have used quantum mechanics to show how it fails. The equivalence principle is one of the more fascinating ideas in modern science. It asserts that gravitational mass and inertial mass are identical. Einstein put it like this: the gravitational force we experience on Earth is identical to the force we would experience were we sitting in a spaceship accelerating at 1g. Newton might have said that the m in F=ma is the same as the ms in F=Gm1m2/r^2. This seems eminently sensible. And yet it is no more than an assertion. Sure, we can measure the equivalence with ever increasing accuracy but there is nothing to stop us thinking that at some point the relationship will break down. Indeed several modifications to relativity predict that it will. One important question is what quantum mechanics has to say on the matter. But physicists have so far been unable to use quantum theory as a lever to tease apart the behaviour of inertial and gravitational mass.

Home World News Latest Articles Escape Hatch ... Endless Buzz Basics of Quantum Mechanics for Dummies Next time when a Physics Professor says that the probability of your position at any given time, in the whole universe, is never zero, don't think he has lost his marbles. This is where we can start with the basics of Quantum Mechanics for dummies. Just read on... According to Niels Bohr, the father of the orthodox 'Copenhagen Interpretation' of quantum physics, "Anyone who is not shocked by quantum theory has not understood it". As seen by a layman, quantum mechanics appears to be more like a bizarre phenomenon or science fantasy flick, full of jargons and complicated mathematical equations. However, it is easier to take a look at the basics of quantum mechanics for dummies, provided one isn't baffled by the fact that every electron is a particle, as well as a wave at the same time. Introduction to Quantum Mechanics Quantum mechanics is the branch of physics which deals with the study of particles to the extent of atomic and sub-atomic level. The term 'Quantum Mechanics' was given by Max Born in 1924. With the discovery of electron, by J.J. Thomson, in the year 1932, the whole idea of classical physics was shown to be inapplicable at the atomic level. Classical physics which was governed by the Newton's laws of motion and Maxwell's laws of electromagnetism, was used to define and predict the motion of particles. But this theory was not able to explain the following three critical and world famous experiments:

His father was C Subrahmanyan Ayyar and his mother was Sitalaksmi Aiyar. His father, an Indian government auditor whose job was to audit the Northwest Railways, came from a Brahman family which owned some land near Madras, India. Chandra came from a large family, having two older sisters, three younger brothers and four younger sisters. When Chandra was still young his parents moved to Madras and, as he grew up, he was encouraged to seek an education which would see him following his father into government service. However Chandra wanted to be a scientist and his mother encouraged him to follow this route. He had a role model in his paternal uncle Sir Chandrasekhara Venkata Raman who went on to win the Nobel prize in 1930 for his 1928 discovery of Raman scattering and the Raman effect, which is a change in the wavelength of light occurring when a beam of light is deflected by molecules.

Uncategorized You are here: Home Video game review: ‘Quantum Theory’ not the brightest gaming idea Video game review: ‘Quantum Theory’ not the brightest gaming idea Posted on25 October 2010. By Bryan Dunagan The Northern Light , U. Alaska via UWIRE It’s a shame that the first shooter that comes from Tecmo is a lame duck. The game starts out with brooding hero Syd escaping from a collapsing tower called an Ark. By his side is Nyx, a heroine that fights with a sword. It’s an interesting concept in a shooter to have a character that relies almost solely on melee fighting, and leads to an interesting dichotomy; the player can work through the female sidekick to attack a large enemy. Unfortunately, Nyx dies and Syd escapes and laments that everyone he fights with dies. So starts the story, with Syd brooding more than ever. After he meets up with a contingent of soldiers later on, who are afflicted with a tower that is consuming and changing the nearby populace. The game has great ideas, changing battlefields, a buxom heroine sidekick and interesting melee combat. Not to mention a mildly interesting story and coupled with some decent graphics, but it is basically a terribly re-skinned version of “Gears of War.” Where it excels however, is with an interesting melee system. Tapping “x” and timing it right by watching a contracting circle allows the gamer to pull off a pretty cool melee combo attack.

Syracuse University Directories MySlice Contact ... News Home SU News Syracuse University physicists develop model that pushes limits of quantum theory, relativity August 02, 2010 Judy Holmes However, a team of Syracuse University physicists recently developed a new theoretical model to explain how the Pauli exclusion principle can be violated and how, under certain rare conditions, more than one electron can simultaneously occupy the same quantum state. Their model, published July 26 in Physical Review Letters (vol. 105) may help explain how matter behaves at the edges of black holes and contribute to the ongoing scientific quest for a unified theory of quantum gravity. Physical Review Letters is a publication of the prestigious American Physical Society. Physics College of Arts and Sciences Balachandran is the lead author on the paper with Ph.D. candidates Anosh Joseph and Pramod Padmanabhan. The orderly way in which electrons fill up atomic levels provides stability and structure to matter, as well as dictates the chemical properties of elements on the Periodic Table. Underlying this stability is the ability to pinpoint the location of objects (electrons, protons and neutrons) almost exactly in space and time. The new model posits that at the level where quantum gravity is significant, this picture of space-time continuum breaks down, deeply affecting the rotational symmetry of the atoms and triggering electron transitions (movement from one shell to another) that violate the Pauli principle.

108. Discussions With Einstein On Epistemological Problems In Atomic Physics Report by Niels Bohr of his discussions with Albert Einstein over many years on the epistemological implications of quantum theory. http://www.marxists.org/reference/subject/philosophy/works/dk/bohr.htm

Niels Bohr (1949) Discussions with Einstein on Epistemological Problems in Atomic Physics Source : From Albert Einstein: Philosopher-Scientist (1949), publ. Cambridge University Press, 1949. Neils Bohr's report of conversations with Einstein and Einstein's reply. WHEN invited by the Editor of the series, Living Philosophers With unfailing intuition Einstein thus was led step by step to the conclusion that any radiation process involves the emission or absorption of individual light quanta or "photons" with energy and momentum E hf and P hs respectively, where h is Planck's constant, while f and s are the number of vibrations per unit time and the number of waves per unit length, respectively. Notwithstanding its fertility, the idea of the photon implied a quite unforeseen dilemma, since any simple corpuscular picture of radiation would obviously be irreconcilable with interference effects, which present so essential an aspect of radiative phenomena, and which can be described only in terms of a wave picture. The acuteness of the dilemma is stressed by the fact that the interference effects offer our only means of defining the concepts of frequency and wavelength entering into the very expressions for the energy and momentum of the photon. In this situation, there could be no question of attempting a causal analysis of radiative phenomena, but only, by a combined use of the contrasting pictures, to estimate probabilities for the occurrence of the individual radiation processes. However, it is most important to realize that the recourse to probability laws under such circumstances is essentially different in aim from the familiar application of statistical considerations as practical means of accounting for the properties of mechanical systems of great structural complexity. In fact, in quantum physics we are presented not with intricacies of this kind, but with the inability of the classical frame of concepts to comprise the peculiar feature of indivisibility, or "individuality," characterising the elementary processes.

The theory describes only the way systems affect each other in the course of physical interactions. State and physical quantities refer always to the interaction, or the relation, between two systems. Nevertheless, the theory is assumed to be complete. The physical content of quantum theory is understood as expressing the net of relations connecting all different physical systems. 1. Introduction 1.1 The problem 2.

The theory is the core component of the momentous change that our understanding of the physical world has undergone during the first decades of the 20th century. It is one of the most successful scientific theories ever: it is supported by vast and unquestionable empirical and technological effectiveness and is today virtually unchallenged. But the interpretation of what the theory actually tells us about the physical world raises a lively debate, which has continued with alternating fortunes, from the early days of the theory in the late twenties, to nowadays.

Up to home page Quantum Gravity Quantum gravity is the study of theories which incorporate known gravitational and quantum phenomena. This usually involves the assumption that gravity is itself a quantum phenomenon. This can be studied by considering the more general class of quantum field theories which exhibit general covariance. This subject is called topological quantum field theory , or TQFT. Quantum gravity was originally studied, by Dirac and others, as the problem of quantising general relativity, considered as a dynamical system. This approach has many difficulties, detailed by Isham in Quantum gravity, an Oxford Symposium, 1975, OUP The newer approach consists of abandoning the idea of general relativity as a dynamical system, and considering instead the quantum field theory of manifolds . In particle physics, the ideal is that each Lorentzian or Riemannian manifold gives rise to a law of propagation of quantum fields, once the internal structure is specified (gauge group, fields, interactions). The isometries of the space become symmetries of the quantum field theory. In a TQFT, each manifold gives rise to a quantum propagation law. The mappings of manifolds are symmetries of this theory. In this way, quantum gravity is

116. How Gravity Works At Microscopic Scales Discusses in simple terms the problem of constructing a quantum theory of gravity. http://www.jupiterscientific.org/sciinfo/gravity.html

How Gravity Works at Microscopic Scales The Greatest Unsolved Problem of 20th-Century Theoretical Physics Is the Construction of a Quantum Theory of Gravity. I saac Newton understood gravity in a rather mechanical way. (1) Objects with mass simply attract each other. The more mass they have, the stronger the attraction. (2) The force weakens as the separation between bodies increases. (This, by the way, explains why distant stars do not produce a significant pull on us on Earth they are too far away.) (3) Gravity is a very weak force. Hence, only very massive objects such as the Earth and the Sun can produce a sizeable gravity. Einstein understood gravity in a more natural way. The essential idea is that space is dynamic. This means that space can stretch, bend and be deformed. But what causes space to change its shape? The answer is mass. Massive objects cause space to curve. Now a second body moving in this curved space will not move in a straight line. By definition, it must be accelerating. Acceleration is the change in speed or the change in direction of motion. But since forces are things that cause accelerations, the first object must be producing a force. In this way, Newtonian gravity is reproduced by the Einsteinian viewpoint. In summary, gravity is the consequence of the curving of space. There is a simple analogy used in the book The Bible According to Einstein that illustrates how this works. If you take a bowling ball and place it on a bed, then the surface around the bowling ball will depress. If you then toss a marble onto the bed, the marble will roll toward the bowling ball. It is as though the marble is attracted to the bowling ball. In this analogy, the surface of the bed is like physical space, the bowling ball is like the Earth and the marble is like an apple. When tossed, the apple heads toward the Earth, just as the marble does toward the bowling ball.
