Relativity The theory of relativity is traditionally broken into two parts, special and general relativity. Special relativity provides a framework for translating physical events and laws into forms appropriate for any frame of reference. General relativity addresses the problem of accelerated motion and gravity. Special Theory of Relativity A key problem for Newtonian physics was the need for absolute space and time when referring to events or interactions. In particular, the problems of light propagation required an medium, an ether, for the light waves to exist within. The Michelson-Morley experiment showed that there was not absolute space and that inertial frames were relative only to themselves. The key point to special relativity is that the speed of light (c=186,000 miles per sec) is constant in all frames of reference. What this means can be best demonstrated by the following scenario: In Newtonian mechanics, quantities such as speed and distance may be transformed from one frame of reference to another, provided that the frames are in uniform motion (i.e. not accelerating). In special relativity, there is a natural upper limit to velocity, the speed of light. And the speed of light the same in all directions with respect to any frame.

The Special Theory of Relativity (SRT). Concepts, foundations and critical analysis. by: Marcelo A. Crotti First version ( in Spanish ) : Nov 6 th Last modification: Sep 22 th This page is not designed for amusement. But I hope it will be kind of entertainment to read it. Developing this topic, I am trying to contribute to the diffusion (from my own point of view) and general understanding of the concepts behind the special theory of the relativity which, together with the quantum theory, redefined the physics and the philosophy of 20th century. In agreement with the time that I have invested to understand and to adapt the Special Theory of Relativity to my own way of thinking, the development of this page has taken me many months. The work is far from being finished, so, I will be indicating the date whenever I make changes or additions in the different subjects. This page is not directed to those making their first approach to the concepts of Special Relativity Theory (SRT). However, based on reiterated requirements, I have added a small introduction that embraces scientific and conceptual historical topics, intimately bound to the development of this theory. To obtain better benefits from the different developments and discussions it is convenient to know: The foundations of the Michelson-Morley experiment.

C-ship: Relativistic ray traced images Welcome aboard C-ship , exploring flight near the speed of light! C-ship helps you understand Einstein's theory of Special Relativity intuitively through the medium of computer-synthesised images. To view the images in this document, you need a graphics-oriented Web browser. We'll be looking at lots of pictures on our journey. Sending large pictures across the Internet consumes precious network bandwidth and can take a long time. So, I'll show small "thumbnail" views of most pictures, with words "GIF" and "JPEG" beneath the image. When you click on the word, you'll see the full-size image. Most of the images are understandable from the thumbnail views. It's up to you which images you'd like to examine in more detail. If your browser supports in-line JPEG images, click on JPEG, otherwise use GIF. JPEG images look much better and take much less time to transmit to your computer, but not all Web browsers understand them.

Albert Einstein proposed the Special Theory of Relativity in 1905. This "theory" has had a major impact on all our lives, although you may not think so. The purpose of these Web pages is to try to relate the theory in a clear understandable way, with the mathematics and technicalities kept out of the way, unless you really want to know about them. While relativity has a reputation for being difficult much of it can be understood by anyone (and all of it by no one!).

Forward Back Up Map ... Information What's So Special About Relativity? Einstein's first theory of relativity, which he published in 1905, broke away from the Newtonian reliance on space and time as immutable frames of reference. This theory was immediately recognized by the scientific community as having profound implications for physics and cosmology. Einstein's main goal was to address the apparent inconsistencies in Maxwell's electromagnetic theory. No wonder Einstein named his paper The Electrodynamics of Moving Bodies Einstein's 1905 paper on Special Relativity Later to become known as the Special Theory of Relativity , its first postulate was that the speed of light is the same for all observers, regardless of their motion relative to the source of the light. The second postulate was that all observers moving at constant speed should observe the same physical laws. Putting these two ideas together, Einstein showed that the only way this can happen is if time intervals and/or lengths change according to the speed of the system relative to the observer's frame of reference. This flies against our everyday experience but has since been demonstrated to hold in a number of very solid experiments. For example, scientists have shown that an atomic clock travelling at high speed in a jet plane ticks more slowly than its stationary counterpart. JPEG Einstein's discovery of the relativity of space and time led to an equally revolutionary insight. Matter and energy are interrelated, even equivalent. The equivalence of matter and energy is summed up in the famous equation:

59. Special Relativity Made Simple A nonmathematical introduction to the concepts of special relativity. http://www.geocities.com/autotheist/Physics/sr.htm

Advanced Physics Made Simple Special Relativity Introduced by Albert Einstein in 1905, this theory was developed to explain the experiment of Michelson and Morley: The Michelson Morley Experiment Think of a baseball pitcher throwing a baseball at 50 mi/hr from the pitchers mound. Then the ball crosses homeplate at 50 mi/hr. Now suppose the pitcher stands in the back of a truck travelling at 50 mi/hr and throws the ball at 50 mi/hr. Then the ball will cross homeplate at 100 mi/hr. This is just natural. In the late 19th century, Michelson and Morley designed an experiment that replaced the baseball with light, and the truck was replaced by the entire Earth. But what they found was not the obvious solution. They found that light travelled at a constant speed. If the pitcher shines a flashlight at the batter, it goes at the same speed as if the pitcher shines the flashlight from the back of a moving truck. Minkowski Spacetime Actually, Minkowski developed this approach to special relativity after Einstein, but it makes the physics simple. You may have heard that time is a dimension just like space. IT IS NOT LIKE SPACE. Lengths measured in space are positive, and they are always positive. Lengths measured in the time dimension are called IMAGINARY, which means that a given length, multiplied by itself, is always negative. ( Since time is a negative dimension and space is a positive dimension, it is possible to have a total length of zero - this is the case for light)
