Kepler's Sphere Pyramid | STEM

More than just a beautiful geometric shape, this 35-sphere tetrahedral pyramid is a hands-on journey into the history of mathematics and physics! This model is a perfect physical representation of the "Kepler Conjecture" (1611), making it an ideal STEM educational tool for schools, teachers, or math enthusiasts. 🧩 Layered Puzzle Design: Instead of a single solid block, this pyramid is intelligently divided into 5 horizontal layers. Interactive Learning: You can stack the layers one by one to demonstrate the sequence of triangular numbers (1 top, 3 second layer, 6 third layer, 10 fourth layer, 15 bottom layer = 35 spheres total). Show the Inside: It perfectly illustrates the "close packing of spheres" concept and how atomic structures are arranged in 3D space.
