Physics Sweatshirt — Relatively Genius Science Apparel

The "Relatively Genius" design is a clever nod to modern physics, turning big ideas into a clean, bold graphic. Wave and particle motifs hint at the connection between energy and mass, while a curved spacetime grid suggests how gravity can be understood through the geometry of spacetime.

Perfect for: Physics students, Einstein fans, science teachers, and anyone who appreciates clever design that quietly rewards people who get the reference.
