Foundations of General Relativity,ivity came about is that Maxwell’s theory contradicts the notion of pre-relativity spacetime. Next, we will inspect Newton’s laws of motion. As an example, consider the law of conservation of momentum. As we pointed out at the beginning of Sect. ., if the definition of momentum . is still used, then

Rate-Quality Optimized Video Coding. Physics studies the evolution of physical objects. For the convenience of study, people usually use physical models to describe physical objects. Models are the idealized version of objects, such as point masses, point charges, charged surfaces, etc. Now let us introduce a few fundamental concepts

The spacetime of general relativity is also a “continuous 4-d

However, after acquiring an understanding of differential geometry in the previous chapters, one can also use a 4-dimensional “global” way to formulate special relativity, which not only makes it easier to grasp the essence of the theory

Rate-Quality Optimized Video Codingo special relativity, this “law of laws” requires that the mathematical expressions for the laws of physics be Lorentz covariant. Therefore, when formulating physics in the framework of special relativity, all the known laws of physics should be inspected; those that satisfy this requirement remain
