Greetings Dear!
What is stone, or what is water?
What are its molecules, and what are atoms, and what are electrons?
The branch of science in question is quantum physics. But as we move forward, it holds contradictions and mysteries.
Quantum physics describes a world in which no object exists stably, the atom and the electron can be waves or particles depending on their appearance, cats can be alive and dead at the same time, all of which is famous in popular culture and the word quantum itself is to become a word of geek mystification. It's not good for people like us who want to understand this world because we don't have a simple and straightforward answer to what stone is. The theory of quantum mechanics was developed in the first decades of the 20th century to explain quantum physics. It is a great discovery of science and defines us from the atom, the radiation, the basic particle, the basic forces to the properties of materials.
And this wonderful discovery of science also presents some difficulties. His followers had profound differences of opinion about what this theory tells us. Some were angry with him. For some, it was the new breed of revolutionary science that destroyed metaphysical assumptions about nature. The conceptual problems and the main debates that have taken place since its inception are still unsolved. Here the question arises, why the debate about the importance of quantum mechanics, what does it matter? The debate that has been going on for over a century has revolved around the nature of quantum mechanics. Reality and also by their nature science. Two questions for your background to understand this: First, does the natural world exist independently of our minds? That is, does matter have different lying properties than our perception and our knowledge? Second, can these attributes be understood and explained? Enough laws to explain the history of the universe and predict the future? These are very important questions because our answers to these two questions tell us about the nature and purpose of science. What role does science play in the human project? And these questions also relate to the boundary between reality and fantasy. To me Anyone who answers both questions with "yes" is said to be realistic. Einstein was realistic.
His main belief was that the world outside our existence is real, and its properties do not depend on our understanding and knowledge, secondly, it is understandable and explainable. If you are realistic, you believe that the scientific project is to find a way to explain that; If you don't answer both of these questions positively, you are an anti-realist; most scientists are realistic about everyday objects on a human scale. We can pick up, pick up, throw objects that we can see. These objects exist somewhere in space at any given time. When they move, there is a reactive speed to count and a trajectory.
You have bulk and weight. If you tell someone that the red book is on the table in another room, that information may be right or wrong, but it is the explanation of matter that works from small scales to planets and stars is classical physics and was since the time of Galileo, Kepler, Newton and Einstein's theory of relativity. It is a complete success. But on a very small scale, when it comes to a single atom ... it's very difficult to be realistic. And the reason for that is quantum mechanics. Quantum mechanics is our best theory on this scale. And there are many properties that are a mystery. The general idea is that these properties make realism impossible. Most fascists are unrealistic when it comes to basic atoms, radiation or particles. It's not that they want to reject realism because of a certain radical philosophical position. But when quantum mechanics is complete (as most fascists believe) then realism is impossible.
And that was the reason Einstein rejected quantum mechanics as a temporary game that only gives the absolutely correct results. Einstein (and other realists) believe that quantum mechanics is incomplete, and that completing it corresponds to realism. The compatibility of realism and physics was Einstein's mission, which he failed all his life.
