Are there any easy-to-read references?

Newman Penrose Formalism is a mathematical framework used to describe the mathematical properties of spacetime in general relativity. It is based on the use of spinors and tensors to describe the curvature of spacetime and its effects on matter and energy.
Newman Penrose Formalism was developed by mathematicians and physicists Roy Kerr, Ezra Newman, Roger Penrose, and Ted Newman in the 1960s. They aimed to develop a more elegant and powerful approach to solving the Einstein field equations in general relativity.
Newman Penrose Formalism is different from other approaches in general relativity because it uses spinors and tensors to describe the properties of spacetime, rather than traditional methods such as tensors and matrices. This allows for a more compact and elegant formulation of the equations, making it easier to analyze and solve complex problems.
Newman Penrose Formalism has been used in a variety of applications in general relativity, including the study of black holes, gravitational waves, and cosmology. It has also been used in other areas of physics, such as quantum gravity and high-energy physics.
Yes, Newman Penrose Formalism is still used today in various areas of physics and mathematics. It is considered to be a powerful and elegant tool for studying the properties of spacetime and its effects on matter and energy. It continues to be a subject of research and development, with new applications and advancements being made in the field.
