Seeing Relativity Through Einstein's Eyes is a recent multimedia relativistic visualisation work. Real Time Relativity is an interactive relativistic visualisation program. If the speed of light could be reduced from over a billion kilometers per hour to just a few meters per second, the world would look very different. The Australian National University relativistic visualization project has used supercomputers to simulate what we might see in a world where the effects of Einstein's theory of special relativity are everyday experiences.

Albert Einstein and the Theory of Relativity Albert Einstein Newton's theory of gravitation was soon accepted without question, and it remained unquestioned until the beginning of this century. Then Albert Einstein shook the foundations of physics with the introduction of his Special Theory of Relativity in 1905, and his General Theory of Relativity in 1915 (Here is an example of a thought experiment in special relativity ). The first showed that Newton's Three Laws of Motion were only approximately correct, breaking down when velocities approached that of light. The second showed that Newton's Law of Gravitation was also only approximately correct, breaking down in the presence of very strong gravitational fields. Newton vs. Einstein: Albert's Turn to Kick Butt We shall consider Relativity in more detail later . Here, we only summarize the differences between Newton's theory of gravitation and the theory of gravitation implied by the General Theory of Relativity. They make essentially identical predictions as long as the strength of the gravitational field is weak, which is our usual experience. However, there are three crucial predictions where the two theories diverge, and thus can be tested with careful experiments. The orientation of Mercury's orbit is found to precess in space over time, as indicated in the adjacent figure (the magnitude of the effect is greatly exaggerated in this figure). This is commonly called the "precession of the perihelion", because it causes the position of the perihelion to move. Only part of this can be accounted for by perturbations in Newton's theory. There is an extra 43 seconds of arc per century in this precession that is predicted by the Theory of General Relativity and observed to occur (a second of arc is 1/3600 of an angular degree). This effect is extremely small, but the measurements are very precise and can detect such small effects very well.

70. Relativism > The Linguistic Relativity Hypothesis (Stanford Encyclopedia Of Phil But the label linguistic relativity, which is more common today, has the advantage that makes it easier to separate the hypothesis from the details of http://plato.stanford.edu/entries/relativism/supplement2.html

Cite this entry Search the SEP Advanced Search Tools ... Stanford University Supplement to Relativism The Linguistic Relativity Hypothesis Many linguists, including Noam Chomsky, contend that language in the sense we ordinary think of it, in the sense that people in Germany speak German, is a historical or social or political notion, rather than a scientific one. For example, German and Dutch are much closer to one another than various dialects of Chinese are. But the rough, commonsense divisions between languages will suffice for our purposes. There are around 5000 languages in use today, and each is quite different from many of the others. Differences are especially pronounced between languages of different families, e.g., between Indo-European languages like English and Hindi and Ancient Greek, on the one hand, and non-Indo-European languages like Hopi and Chinese and Swahili, on the other. Many thinkers have urged that large differences in language lead to large differences in experience and thought. They hold that each language embodies a worldview, with quite different languages embodying quite different views, so that speakers of different languages think about the world in quite different ways. This view is sometimes called the Whorf-hypothesis or the Whorf-Sapir hypothesis , after the linguists who made if famous. But the label

Real-World Relativity: The GPS Navigation System People often ask me "What good is Relativity?" It is a commonplace to think of Relativity as an abstract and highly arcane mathematical theory that has no consequences for everyday life. This is in fact far from the truth. Consider for a moment that when you are riding in a commercial airliner, the pilot and crew are navigating to your destination with the aid of the Global Positioning System (GPS). Further, many luxury cars now come with built-in navigation systems that include GPS receivers with digital maps, and you can purchase hand-held GPS navigation units that will give you your position on the Earth (latitude, longitude, and altitude) to an accuracy of 5 to 10 meters that weigh only a few ounces and cost around $100. GPS was developed by the United States Department of Defense to provide a satellite-based navigation system for the U.S. military. It was later put under joint DoD and Department of Transportation control to provide for both military and civilian navigation uses. The current GPS configuration consists of a network of 24 satellites in high orbits around the Earth. Each satellite in the GPS constellation orbits at an altitude of about 20,000 km from the ground, and has an orbital speed of about 14,000 km/hour (the orbital period is roughly 12 hours - contrary to popular belief, GPS satellites are not in geosynchronous or geostationary orbits). The satellite orbits are distributed so that at least 4 satellites are always visible from any point on the Earth at any given instant (with up to 12 visible at one time). Each satellite carries with it an atomic clock that "ticks" with an accuracy of 1 nanosecond (1 billionth of a second). A GPS receiver in an airplane determines its current position and heading by comparing the time signals it receives from a number of the GPS satellites (usually 6 to 12) and triangulating on the known positions of each satellite. The precision is phenomenal: even a simple hand-held GPS receiver can determine your

Special Relativity Michael Fowler UVa Physics Index of Lectures and Overview of the Course Link to Previous Lecture Galilean Relativity again At this point in the course, we finally enter the twentieth century Albert Einstein wrote his first paper on relativity in 1905. To put his work in context, let us first review just what is meant by "relativity" in physics. The first example, mentioned in a previous lecture, is what is called "Galilean relativity" and is nothing but Galileo's perception that by observing the motion of objects, alive or dead, in a closed room there is no way to tell if the room is at rest or is in fact in a boat moving at a steady speed in a fixed direction. (You can tell if the room is accelerating or turning around.) Everything looks the same in a room in steady motion as it does in a room at rest. After Newton formulated his Laws of Motion, describing how bodies move in response to forces and so on, physicists reformulated Galileo's observation in a slightly more technical, but equivalent, way: they said the laws of physics are the same in a uniformly moving room as they are in a room at rest . In other words, the same force produces the same acceleration, and an object experiencing no force moves at a steady speed in a straight line in either case. Of course, talking in these terms implies that we have clocks and rulers available so that we can actually time the motion of a body over a measured distance, so the physicist envisions the room in question to have calibrations along all the walls, so the position of anything can be measured, and a good clock to time motion. Such a suitably equipped room is called a "

Web Warp Home About FAQ Lessons ... Reading A Special Relativity Simulator Warp is a program used to illustrate the appearance of everyday objects travelling at really, really high speeds. At such speeds, Einstein's theory of special relativity predicts that unusual things start to happen. Warp models these strange effects - it is a special relativity simulator. Of course, we don't normally see these strange effects and for a good reason. By high speed we mean extremely high speeds - close to the speed of light . We don't normally see these 'relativistic' effects because the speeds associated with every day life don't compare with the speed of light. To whet your appetite, here's what Stonehenge looks like at close to the speed of light . . . Very strange! Anyway, if you want a brief explaination of what's going on then a good place to start is the about page. Once you've done that, try out the Warp special relativity simulator for yourself by downloading it! You'll now be wondering how to use Warp, or maybe you just want to learn more about special relativity. It'll be a good idea to read the Lessons .

About the author Euclidean Relativity Euclidean relativity, both special and general, is gaining attention as a viable alternative to the Minkowski framework. The links section gives a short overview of its main characteristics together with a number of references to articles on Euclidean relativity published by other authors. The Euclidean interpretation of special relativity that you will find on this site provides arguments for a geometrical unification of gravity and electromagnetism, which is worked out in another article. From this unification follows the proposal to regard mass particles themselves, instead of gravitons, as bosons following null geodesics in 5D gravity. The full text of articles is available in web form and as downloadable PDF documents. A simplified and popularized version is also available that should take no more than 30 minutes to read and will get you in the "right mood". A number of speculative ideas, directly or indirectly building on these articles, are over time being worked out here . A fractal-like universe is described where the four forces of nature together with their fermions and bosons are ordered hierarchically through their number of dimensions. 3D graph for relativistic addition of velocities as derived from the Euclidean interpretation Articles Dimensions in Special Relativity Theory- A Euclidean Interpretation A Euclidean interpretation of special relativity is given wherein proper time
