The Simplest Math Problem No One Can Solve - Collatz Conjecture

Veritasium

Summary

El vídeo explica la Conjetura de Collatz, uno de los problemas más fascinantes y complejos de las matemáticas. A pesar de su formulación sencilla , aplicar dos reglas simples a cualquier número entero hasta llegar al bucle 4-2-1, , nadie ha logrado demostrar que todos los números sigan este camino o que no existan secuencias que diverjan al infinito. El autor explora el comportamiento caótico de estos números, la analogía con el movimiento browniano, la ley de Benford y las limitaciones actuales para hallar una prueba definitiva, planteando incluso la posibilidad de que el problema sea indecidible.

Transcript excerpt

this is the most dangerous problem in mathematics one that young mathematicians are warned not to waste their time on it's a simple conjecture that not even the world's best mathematicians have been able to solve Paul erush a famous mathematician said mathematics is not yet ripe enough for such questions here's how it works pick a number any number seven good choice okay we're going to apply two rules if the number is odd we multiply by three and add 1 so 3 * 7 is 21 + 1 is 22 if the number is even we divide by two so 22 ID 2 is 11 now we keep applying these two rules 11 is odd so we multiply by 3 33 and add 1 34 even divide by 2 17 odd multiply by 3 51 add 1 52 even divide by 2 26 still even divide by 2 13 odd so we multiply by 3 39 add 1 and that's 40 which is even so we divide by 2 20 IDE by 2 10 IDE by 2 5 odd multiply by 3 15 add 1 16 divide by 2 that's 8 and then 4 2 and 1 now one…
