Fractional calculus is a branch of mathematical analysis that extends the concept of derivatives and integrals to fractional (non-integer) orders. Traditional calculus deals with whole number orders of differentiation and integration, such as the first derivative \( f'(x) \) or the second derivative \( f''(x) \).

General relativity is a fundamental theory of gravitation formulated by Albert Einstein and published in 1915. It redefined the concept of gravity, moving beyond the Newtonian perspective. Here's an overview of the key features of general relativity: ### Key Concepts of General Relativity: 1. **Curvature of Spacetime**: Instead of viewing gravity as a force that acts at a distance, general relativity describes it as the curvature of spacetime caused by mass and energy.
