Einstein's Theories and Discoveries

The video discusses Einstein's theories of relativity, focusing on his 1915 General Relativity. It explains how Einstein's equations initially predicted an expanding universe, which he doubted due to contemporary astronomical beliefs, leading to the introduction of the 'lambda' term. Later, Hubble's observations confirmed the universe's expansion, allowing Einstein to revert to his original equation. The video also covers Einstein's resistance to quantum mechanics, highlighting his belief in a deterministic universe and his famous disagreement with Niels Bohr.
