Introduces scalar gravity, covering covariant derivatives, Ricci tensor, Einstein Equivalence Principle, and the generalization of Newtonian gravity equations.
Delves into the equilibrium shapes of helical thin rods under weak gravity conditions, focusing on Kirchhoff's rod theory and ordinary differential equations.
Explores the importance of the perfect fluid in cosmology and its coupling to gravity, leading to a discussion on the Einstein universe and static gravity.
