i am really confused about it.i know this much that it is used to cancel out the infinities to combine the theory of relativity and quantum physics.i just want to know how.and also what is super symmetry?please help.
Your paper really helped thank you.A. Neumaier said:Renormalization is primarily a means of reparameterizing a system of differential equations.
In the context you place it (infinities) it is a means for choosing the parameterization such that a singular limit can be taken that gives physically relevant results.
In particular, renormalization is therefore used to give sense to quantum systems defined in terms of singular operators (in quantum mechanics) or fields (in quantum field theory). This is nontrivial since singular objects cannot be handled in the standard way without producing meaningless results. For an explanation how it works in simple cases where one can fully understand the meaning of the infinitis and how to avoid them see my renormalization tutorial.
OkA. Neumaier said:Gauge symmetry is not really related to renormalization. It is instead about the additional difficulties in quantizing constraints.
Renormalization is a mathematical technique used in theoretical physics to address the issue of infinities that arise in certain calculations involving quantum field theory. It involves rescaling certain parameters in the theory to eliminate these infinities, allowing for more accurate predictions.
Renormalization is crucial in order to make sense of many predictions in quantum field theory, which is used to describe the behavior of particles at the subatomic level. By eliminating infinities, renormalization helps to ensure that these predictions are physically meaningful and accurate.
Renormalization involves performing a series of calculations to determine the appropriate rescaling factors for the parameters in a given quantum field theory. These rescaling factors are then applied to the original equations to eliminate the infinities and produce finite, meaningful results.
The concept of renormalization was first introduced in the 1940s by physicists Hans Bethe, Sin-Itiro Tomonaga, and Julian Schwinger. It was further developed by physicist Richard Feynman in the 1950s and became an essential tool in the field of quantum field theory. Renormalization has since been used in various other fields of physics, including statistical mechanics and condensed matter physics.
While renormalization is widely accepted by the scientific community as an important and necessary tool in theoretical physics, there have been some controversies surrounding its use. Some scientists have questioned the validity and physical interpretation of renormalization, while others have proposed alternative approaches. However, renormalization remains a fundamental concept in modern physics and continues to be used in various fields of research.
