In summary, the conversation focused on the role of technology in education, with one person arguing that it has improved learning outcomes while the other believed it has hindered critical thinking skills. They also discussed the importance of balance and proper implementation of technology in the classroom.

here you can check at arxiv.org webpage http://arxiv.org/PS_cache/hep-th/pdf/9507/9507067.pdf [Broken] a theory to avoid divergences in qft non renormalizble theories,with that we are a step closer to final theory,hope it can be helpful.

Was there ever any followup to this paper? Did their methods ever pass the asymptotic test they mention? It seems that their simple algebra would be more widely employed unless there were some hitch.

Renormalization is an essential tool in the study of quantum field theory (QFT), allowing us to make sense of theories that would otherwise be plagued by infinities. However, certain theories, known as non-renormalizable theories, are still not fully understood within the framework of renormalization. These theories have an infinite number of divergences that cannot be removed through the standard renormalization procedure.

In this paper, the authors propose a new approach to renormalizing non-renormalizable theories. By introducing a new set of fields and imposing certain constraints on the interactions between these fields, they are able to eliminate the divergences that would normally arise in QFT calculations. This approach represents an important step towards a complete understanding of these theories and brings us closer to a final theory that can fully describe the fundamental interactions of our universe.

It is exciting to see progress being made in the study of non-renormalizable theories, and this paper provides valuable insights into how we can overcome the challenges posed by these theories. Hopefully, this new approach will prove to be helpful in furthering our understanding of the fundamental laws of nature.
 

1. What does it mean to "renormalize" a non-renormalizable theory?

Renormalization is a mathematical technique used in theoretical physics to account for infinities that arise in certain calculations. In the case of a non-renormalizable theory, these infinities cannot be eliminated completely, but they can be "renormalized" to produce finite, physically meaningful results.

2. Why are some theories considered non-renormalizable?

Generally, a theory is considered non-renormalizable if it contains terms with higher powers of the energy or momentum than the theory's fundamental energy scale. This means that the theory cannot be accurately described at all energy scales, and a cutoff must be introduced to limit the calculations to a certain range.

3. How does renormalization improve our understanding of non-renormalizable theories?

Renormalization allows us to make predictions and calculations in non-renormalizable theories by accounting for the infinities that arise. While the theory may not be fully understood at all energy scales, renormalization allows us to make accurate predictions within a certain range.

4. Are there any limitations to renormalization of non-renormalizable theories?

Yes, there are limitations to renormalization. While it allows us to make predictions and calculations, it does not provide a complete understanding of the theory at all energy scales. Additionally, the cutoff introduced in renormalization can affect the accuracy of the results.

5. Can renormalization be applied to all non-renormalizable theories?

No, not all non-renormalizable theories can be renormalized. Some theories may be fundamentally flawed or inconsistent, and renormalization cannot fix these issues. In these cases, alternative theories must be proposed to accurately describe the phenomenon in question.
