The video explores the Schaefer Conjecture, focusing on finding rational approximations to irrational numbers. It discusses the proof by James Maynard and Demetrius in 2019, which solved a 78-year-old problem in number theory. The video explains how rational approximations like 22/7 for Pi help understand irrational numbers. It delves into error bounds, showing how to find solutions using functions and inequalities. The Euler Totient and Zeta Function are introduced to explain infinite solutions. Finally, the video tests more ambitious error bounds, highlighting their challenges and limitations.
