        Instead of only reading equations, users can explore how physical systems behave
        by adjusting parameters, observing animations, and connecting theory with motion,
        fields, and measurable quantities.

        ### About the developer

        **Cherian P Ittyipe**  
        Physics & Astrophysics Graduate  

        This project reflects my broader interest in computational physics, scientific
        visualisation, and building interactive tools for understanding physical systems.
        While my primary academic focus is cosmology, this lab reflects a
        broader approach to connecting theory, simulation, and physical understanding through
        interactive tools.
