A bola da Copa é um TETRAEDRO (e isso NUNCA aconteceu antes)

➡️Participate in the Launch of Mastering Calculus: Multiple Variables https://temciencia.com.br/pre-docvv Did you know that the 2026 World Cup ball, the Trionda, is mathematically a tetrahedron? In this video, we'll talk about the World Cup balls since the 1970 World Cup, and the mathematical shape of each one – not from a geometric point of view, but from a topological one. And the heart of the topology of the balls lies in the famous Euler characteristic, or Euler relation, V - A + F = 2, which relates vertices, edges, and faces of a convex polyhedron. And with this, we can show that it's impossible to construct a ball using only hexagonal seams. ➡️ Learn real Calculus, starting from scratch (pre-calculus!) to an advanced level and become unrecognizable!
