The concept of mass in relativity

In summary, Pete has been discussing the concept of mass in relativity and has recently completed a manuscript on the subject. He has put it up on his website for interested individuals to read. However, there have been issues with accessing the link to the manuscript, but Pete provides a new link for a better version. There is also a discussion on the terms of service for posting links on message boards.

I've posted a lot here in the past on the concept of mass in relativity. All of my posts were neccesarily inadequate to due justice to the concept. I've put off being precise on the concept until I as finsished with a manuscript I wanted to write on this subject. I completed it and have put it on my website for those very few people interested in the subject to the extent that they want to read a very long paper. :biggrin:

I've been having the darndest problem with that. It seems as if the PDF file/link works for some and not for others. I don't know what to do about it.

Any ideas anyone?

Thanks

Pete

It's because you've posted it as a link on a message board, which is againt the terms of service of Yahoo. If you copy the adress and paste into the IE address bar you can acess this page.

This link is better and doesn't contain the many mistakes and missrepresentations in that paper:

Where does it say that? I looked at -

http://docs.yahoo.com/info/terms/
http://docs.yahoo.com/info/terms/geoterms.html

and didn't see anything to that effect. Can I do it like this -

Go to

Click on first article. Does that work?

Pete

Yes your homepage works.

It's because the first link you posted is a file (PDF) rather than a webpage, Yahoo don't like people accessing file swithout going trough the homepage becaus eit bypasses their advertising:

What is the concept of mass in relativity?

The concept of mass in relativity is the idea that an object's mass is not a fixed quantity, but rather depends on its velocity and the observer's frame of reference. This is known as the theory of relativity, proposed by Albert Einstein in the early 20th century.

How does relativity change our understanding of mass?

Relativity challenges the traditional notion of mass as a constant property of an object. Instead, mass is viewed as a form of energy and can change depending on the object's speed and the observer's perspective.

What is the difference between rest mass and relativistic mass?

Rest mass, also known as invariant mass, is the mass of an object when it is at rest in a particular frame of reference. Relativistic mass, on the other hand, is the mass of an object when it is in motion and takes into account its velocity and the effects of relativity.

Why is the concept of mass important in relativity?

The concept of mass in relativity is important because it helps us understand the relationship between energy and mass, and how they are interchangeable. This understanding has led to many technological advancements, including nuclear energy and particle accelerators.

Is mass the same as weight in relativity?

No, mass and weight are not the same in relativity. Mass is a fundamental property of an object, while weight is a measure of the gravitational force acting on an object. In relativity, weight can vary depending on the strength of gravity, but mass remains constant.
