We all know the earth is rotating around its own axis. From a physics energy point of view, some thing has to provide energy for the rotation. What provides the energy to rotate?
When I first looked into number theory, I was surprised about why mathematicians are so obsessed about integers, primes and so on. As far as I understand, (almost) all integers in the real world arise as an approximate description of composite dynamics.
I think anyone here understands why individ...
I'm working on the Eq.9.77 in Peskin (page 304)
However, I test the identity and find it doesnʻs work.
For $B=\{\{3, -2, 4\}, \{-2, 6, 2\}, \{4, 2, 3\}\}$, The left-hand side of the Eq.(9.77) is -98, and the right is 54.
Why does this happen? What are the conditions for this identity to be true...
