Einstein's Special Theory of Relativity E=mc2 speed of light

http://www.myspace.com/acorvettes The steps Einstein took to develop his special theory of relativity are as follows: First, Einstein tried to understand what must be implied by the fact that light travels at a speed independent of its source. From this, he realized that time and space are not simply two unrelated concepts; rather, they must be linked in a space-time system whose properties appear most dramatically when objects move very fast and are observed by two different observers moving with respect to one another. His final and greatest step led him to discover and clarify mathematically many new things about the world that are important in each and every frame of reference. In each and every frame of reference, there are relationships that hold because of the nature of space and time. If space and time were to be reconceived in a new interactive way, then other things, like momentum and energy, had to be reconceived, too. In fact, momentum and energy are linked like space and time.

Simultaneity - Albert Einstein and the Theory of Relativity

Imagine two observers, one seated in the center of a speeding train car, and another standing on the platform as the train races by. As the center of the car passes the observer on the platform, he sees two bolts of lightning strike the car - one on the front, and one on the rear. The flashes of light from each strike reach him at the same time, so he concludes that the bolts were simultaneous, since he knows that the light from both strikes traveled the same distance at the same speed, the speed of light. He also predicts that his friend on the train will notice the front strike before the rear strike, because from her perspective on the platform the train is moving to meet the flash from the front, and moving away from the flash from the rear. But what does the passenger see? As her friend on the platform predicted, the passenger does notice the flash from the front before the flash from the rear. But her conclusion is very different. As Einstein showed, the speed of the flashes as measured in the reference frame of the train must also be the speed of light. So, because each light pulse travels the same distance from each end of the train to the passenger, and because both pulses must move at the same speed, he can only conclude one thing: if he sees the front strike first, it actually happened first. Whose interpretation is correct - the observer on the platform, who claims that the strikes happened simultaneously, or the observer on the train, who claims that the front strike happened before the rear strike? Einstein tells us that both are correct, within their own frame of reference. This is a fundamental result of special relativity: From different reference frames, there can never be agreement on the simultaneity of events.

Visualization of Einstein's special relativity

This video demonstrates the effects of Einstein's special relativity on objects that move at high velocities. More particularly, it visualizes the Lorentz transformation. The video shows a 3-dimensional view containing 2 dimensions of space and one dimension of time. This view is used to demonstrate the difference between classical physics and Einstein's relativity, and why the latter was necessary to understand experimental results.

Relativity - The Train Paradox (Time Dilation and Length Contraction)

The train paradox is a famous example of the strangeness of relativity. Demonstrates just how non-intuitive reality can be. Described here by Professor Richard Muller of the University California, Berkeley. Taken from Lecture 22 of the spring 2006 webcasts of Physics For Future Presidents. Also known as Descriptive Introduction to Physics. Empahsis is on conceptual understanding, rather than mathematics.

Optical Effects of Special Relativity

The video shows photorealistic representations of reduced c scenes. This means that the speed of light has been slowed down from over one billion kilometres per hour to a speed of only one meter per second. The consequences of this fiction have been restricted to optical effects, and allows us to see special-relativistic effects not possible in everyday life. The first scene is a trip down a highway without any relativistic effects. Note the position and orientation of the structures in the desert. For the next trip, we enable relativistic aberration. As we accelerate, note that the angular compression creates an initial impression of backwards motion. As we pass the sign, it seems to rotate around. This can be viewed as a Terrell rotation, or as angular aberration keeping the sign in our field of view as we pass it. The back walls of the building are also visible, and extreme distortion is visible on all the objects. Note particularly the sky, steadily shrinking down to the vanishing point. We now enable Doppler shifting. Note that the red desert is blue-shifted ahead through the green and red, causing a rainbow effect. As the blue of the sky is further blue-shifted, it drains of colour. Near the edges of the image, the opposite happens - the sky takes on a reddish hue and the road is drained of colour as the red desert shifts into the infra-red. With full relativistic effects (now including the headlight effect) the image quickly turns monotone, with objects near the edge of the screen darkened, and the centre brightly illuminated. The Terrell effect can be illustrated with this flyby of a cube. Note the orientation of the cube change. Also compare it's apparent position with the position indicated on the HUD map. Remember, we are seeing the cube as it was, not as it is. If we instead fly through the cube, the structures Terrell rotate independently, seeming to turn the cube inside out. Note that even when we have exited the back of the cube, aberration keeps most of it in view. Another property of aberration is that it preserves circles - that is, a sphere will always present a spherical outline to any observer regardless of their relative motion. We see this demonstrated by flying a camera around the Earth at high speed. Though the camera is very close to the surface, aberration wraps the Earth into our forward field of view. But because we are so close to the earth, we can see only a small portion of its surface - so small regions, about the size of Borneo seem to bulge out and fill the sphere.

E=mc2 Time and Relativity special theory of relativity 2

Einstein showed, mathematically, that space and time are related and perceived differently by different observers. One consequence of special relativity is time dilation, which means that time in a moving reference frame passes more slowly than time in a stationary reference frame. In other words, a clock that is moving with respect to a stationary observer is perceived by the observer to run more slowly than a stationary clock. Another consequence is length contraction—the observed decrease in length of objects traveling relative to an observer. As part of the special theory of relativity, Einstein also reconceived our understanding of momentum and energy. As the speed of an object approaches the speed of light, its inertia, or resistance to acceleration, also increases. In other words, its mass increases. Additionally, the theory yielded the famous equation E=mc2, which expresses the relationship between energy and mass.

Einstein Relativity theory declares aether necessary!

In science it is said that the einstein relativity theory proved that aether doesn't exist! This is totally false and has been supressed on purpose, to avoid people from thinking of free energy devices running on aether! I hope this will give ideas to many as it should have happened decades ago! Extract from: the race to Zero-point energy
