Discussion Overview

The discussion revolves around the validity of a proposed conversion factor for mass-energy equivalence, specifically a formula presented as an alternative to the Lorentz gamma factor. Participants explore its implications in the context of special relativity and its application to phenomena such as atomic bombs.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Meta-discussion

Main Points Raised

  • One participant claims that the formula γ = 1 / √(1 + v²/c²) can derive the mass-energy equation and fits atomic bomb modeling better, while others challenge this assertion as incorrect.
  • Another participant argues that if the formula had a minus instead of a plus, it would represent the Lorentz gamma factor, which is essential in special relativity and related to the derivation of E=mc².
  • Concerns are raised about the lack of a source for the original formula, suggesting that it may be misunderstood or incorrect.
  • Several participants express skepticism regarding the validity of the proposed formula, labeling it as a "crackpot idea" and asserting that the mainstream definition of the gamma factor is well-established in relativity.
  • Discussions about the source of the formula include requests for links to the original paper, which is noted to be in Chinese and not peer-reviewed, raising further doubts about its credibility.
  • Participants note that the provided image of the paper is mostly illegible and does not contribute to the discussion, with some questioning whether it is worth further examination.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the proposed conversion factor, with multiple competing views on its applicability and correctness. The discussion remains unresolved regarding the formula's legitimacy.

Contextual Notes

Limitations include the unclear status of the original source, the lack of peer review, and the potential misunderstanding of the formula's implications in the context of special relativity.

γ = 1 / √(1 + v²/c² )

Someone posted above formula, claiming that this conversion factor can also be used to derive the mass-energy equation. Therefore, it's the second formula in the world to do so. Furthermore, the atomic bomb fits this conversion model even better.

I think this is incorrect. That formula is useless.

I'd appreciate your expert opinions.

If there were a minus not a plus in the denominator it would be the Lorentz gamma factor, which is a part of SR and arguably a part of the derivation of things like ##E=mc^2## (or ##E=\gamma mc^2##, which is a more general formula including kinetic energy).

As written, it's no part of relativity.

"Someone posted" is not a good start to a thread, as without the source we have no way of knowing whether you've misunderstood something or the source is just plain wrong.

If someone is claiming that ##\gamma=\frac{1}{\sqrt{1+(v^2/c^2)}}## can be used to better model something than ##\gamma=\frac{1}{\sqrt{1-(v^2/c^2)}}## that sounds to me like a crackpot idea.

The latter is simply a definition used throughout relativity as part of the modeling process. It's mainstream. The former is unheard of, so if someone is claiming it's a discovery of an idea missed by mainstream physics they are deluded.

Nonsense.

Besides, gamm favtor with + sign would give wrong non-relativistic limit.

You're right.

Your image is mostly illegible and does not help. Post a link to the paper please. Also, it does not appear to be published in a peer-reviewed journal, which will be a problem here at PF.
 
A google search turns up a date of Jan 14, 2008, but the link to the paper (http://www.paper.edu.cn) is broken.

With a bit of magnification I was able to read every word. It's the abstract, not the paper itself. It doesn't appear to be worthy of publication. I could comment more, but I don't know if it's worth the time and effort to do so.

Sorry. The paper is in Chinese. Only the Abstract is in English.

Thank you for the much clearer image. Can you post a link, or is the link old and broken as @Herman Trivilino reports?

Here you are. The link works. Just verified. In chinese though.

I'm still waiting on Google to translate the Chinese version to English so that I can review it, but so far it appears to be nonsense that is self-published. That does not meet our PF rules criteria of peer-review in the Clarivate list of acceptable journals. Thread is closed for review of the reference.

It is nonsense. The thread can remain closed.
