How to understand what even Feynman did not understand

The author presents a revised version of their article dedicated to a deep understanding of quantum mechanics. The material is based on Richard Feynman's famous statement that no one understands quantum mechanics. The author argues that since that statement was made, science and philosophy have advanced significantly, making quantum theory accessible to a wider audience. The article revisits old approaches to presenting the material, corrects inaccuracies, and offers a new perspective on fundamental physical concepts. The author's goal is to prove that modern knowledge allows us to overcome barriers that seemed insurmountable even to the great physicists of the past. The article encourages readers to rethink the complexity of the quantum world and asserts that with desire and the right approach, anyone can grasp the basics of quantum mechanics, making this material an important contribution to the popularization of science.
