**Course description:**

1. We start by explaining the problem with Galileo's principle and Maxwell's equations and how this led to the formulation of Special Relativity.

2. We expand the discussion to General Relativity and highlight the importance of mathematical intuition in fully grasping the concepts.

3. We motivate every equation in the course to help students understand the underlying principles and theories.

4. We provide a comprehensive explanation of Lagrangian mechanics and tensors, which are essential to understanding Special and General Relativity.

5. We assume a prerequisite knowledge of Calculus and Multivariable Calculus, including the divergence theorem, vectors, dot and cross products, matrix multiplication, and determinants.

6. We suggest some basic knowledge of Classical physics, including scalar potential, Newton's laws, kinetic energy, energy conservation, and the wave equation.

7. The first part of the course will focus on Lorentz transformations and derive them in two different ways, providing a simpler mathematics to follow along.

8. The second part of the course will focus on General Relativity, where a pencil and paper are recommended to derive the equations, ensuring that students meet the prerequisite requirements.

9. We provide students with a comprehensive understanding of Special and General Relativity and inspire them to appreciate and apply the theories.
