## Mistake Identification – Algebraic Method (Easier Method)

On February - 6 - 2009

Here we summarize Einstein’s Xi derivation as given in his 1905 paper. As illustrated in the following figure, Einstein begins with one math statement and then performs three algebraic substitutions.

## Revised Model Equations

On February - 3 - 2009

Purpose

Given the introduction of Complete and Incomplete Coordinate Systems, we use the example of a bird flying in the cage on the back of a moving truck to create our equations for an Incomplete Coordinate System. In this case we use three birds; one flying from the back to the front and returning to the back, traveling along the X axis, one flying from the left side of the cage to the right and back to the left, traveling along the Y axis, and one flying from the bottom of the cage to the top and back to the bottom, traveling along the Z axis. Each bird is a surrogate for a wave.

## Revised Postulates

On February - 2 - 2009

Complete and Incomplete Coordinate System Postulates

Using the examples given when defining Complete and Incomplete Coordinate Systems, when the velocity of the truck, v, meets or exceeds that of the bird, w, the bird in the cage will never be able to reach the front of the cage. Yet, the bird in the trailer will be able to reach the front of the trailer. Because the behavior within a Complete Coordinate System is different than in an Incomplete Coordinate System, we have to revise Einstein’s original postulates as:

## Revised Coordinate System Model

On February - 2 - 2009

Coordinate Systems

In Einstein’s model, he defines one type of coordinate system. He then applies the postulates and equations to this single type of system. When this coordinate system is moving at velocity v, Einstein concludes that everything within this coordinate system must behave according the same laws of physics.

## The Speed of Light is not a Theoretical Speed Limit

On February - 1 - 2009

In the model of Complete and Incomplete Coordinate Systems, there is no upper limit on the velocity of a moving coordinate system. In order to explain why this is the case, we have to first understand the reasons behind the belief that Einstein’s equation limit velocity. Einstein presents his final equations as:

## The New RelativityChallenge.com (BETA)

On February - 1 - 2009

I’ve been talking about updating my website for some time. The main goals were 1) to make it easier to update and maintain and 2) make it support dynamic content. This site also integrates the website with the blog. Previously they have been two different sites. While they are now integrated, the main podcast feed still originates from the blog site. I’m hoping to make the transition seamless for those who have already subscribed.

As you navigate the site, you may find that some of the material is changed. Over the next few months, I will be updating the content to bring it in line with my latest thinking and research. For example, in the Mistakes section, I now present only two analysis; one for people comfortable with algebra, and a second for the more advanced person who is comfortable with function syntax and scope rules.

Overall, I am happy with how the new site has turned out and welcome your feedback on what I can do to make it better. So, after you’ve had a chance to navigate around, please feel free to drop me an e-mail at Email@RelativityChallenge.com and let me know what you think.

Cheers!

## Comparison of CICS and SRT Equations

On February - 1 - 2009

There are several similarities and differences between the models established by Einstein, Newton, and Bryant. The following table illustrates some of the differences for each with respect to their Fixed Point, Wave Front, and One-Half Oscillation equations.
