In my earlier Insight Spacetime Diagrams of Light Clocks,
I stated without proof that the areas of all light-clock diamonds are equal.
In my article,Relativity on Rotated Graph Paper, Am. J. Phys. 84, 344 (2016)
I provided algebraic proof.

In the penultimate draft, I had a non-algebraic motivating argument (which also motivates time dilation and length contraction)
that had to be left out because the article was already too long.
This argument now appears in Introducing relativity on rotated graph paper...

Hello,

Thank you for sharing your insights on teaching special relativity without relying on the concept of simultaneity. I believe that your approach of using rotated graph paper is a creative and effective way to introduce the concepts of time dilation and length contraction.

I also appreciate your efforts in providing a mathematical proof for the equal areas of light-clock diamonds. While a non-algebraic argument may be easier for students to understand initially, having a formal proof can help solidify their understanding and provide a deeper appreciation for the principles of special relativity.

I believe that your approach of using visual aids and practical examples, such as the light-clock diagrams, is crucial in teaching complex concepts like special relativity. I understand the importance of using both mathematical and visual representations to fully grasp the intricacies of a theory.

I look forward to reading your article and incorporating your ideas into my own teaching of special relativity. Thank you for sharing your valuable insights and contributing to the advancement of science education.

## 1. What is the purpose of "Introducing Relativity on Rotated Graph Paper"?

The purpose of this paper is to provide a graphical representation of the principles of relativity, making it easier for students to understand and visualize complex concepts.

## 2. How does the use of rotated graph paper help in understanding relativity?

Rotated graph paper allows for a visual representation of the effects of relativity, such as time dilation and length contraction, which can be difficult to understand through traditional mathematical equations.

## 3. Is this paper suitable for all levels of understanding in relativity?

Yes, this paper is suitable for both beginners and those with a more advanced understanding of relativity. The graphical approach can help clarify concepts for beginners, while also providing a new perspective for those with a deeper understanding.

## 4. Are there any limitations to using this graphical approach for understanding relativity?

While this approach can help with visualization, it should not be the sole method of learning relativity. It is important to also understand the mathematical equations and principles behind the concepts.

## 5. Can this approach be applied to other complex scientific concepts?

Yes, this approach of using graphical representations can be applied to other complex scientific concepts, such as quantum mechanics or thermodynamics. It can help make these concepts more accessible and easier to understand.
