Physics World

Purpose of this section

This section of New England Physics (NEP) is a temporary place holder for what remains of what was formally called Physics World, which itself was created when the founder of NEP, Peter M. Brown, first started discussing physics online in forums and newsgroups. It was found to be very difficult to discuss certain topics precisely since the language of physics is mathematics and sending math symbols in forums, newsgroups and in e-mail, can't be done, at least not at the time the it was created. So Physics World was created as a place holder for the derivations and diagrams needed to explain various concepts and ideas to various people who were asking questions. These pages were not created to teach physics, i.e. they are not created to be tutorials although they may serve that purpose. Providing physics tutorials is part of what NEP was created for.

Articles by Founder: The following articles were written by the founder, Peter M. Brown, and proof read by several colleages to ensure that the number of mistakes that may have crept in have been minimized. They were all reviewed by well-known experts in the field of relativity. Only the first one was published. It was first plageiarized  by someone who then published it under their name in an Indian Journal as well as placed in a book they wrote. Therefore the first article has been through the peer review process. They were all reviewed by relativists who are well known in their field. All three aree under revision and will someday be submitted to a journal for publication, except for the second one, which I don't believe is something that should be published. It's not that special of a subject. It was only written to describe an easy way to arrive at E = mc2.
