What is The True Nature of Reality?

“In the video we introduced Heisenberg’s uncertainty principle in terms of the effects of a measurement (what is sometimes called the observer effect). The two concepts are not exactly the same, but the observer effect provides an intuitive physical interpretation of the uncertainty principle—in fact Heisenberg himself used it as a physical justification of his principle. A more precise way to introduce Heisenberg’s principle is to see that very small objects, such as elementary particles, behave like waves: a famous experiment in quantum mechanics shows that electrons going past an obstacle “diffract”, i.e. they go around the obstacle. This is similar to how sound waves behave: if you sit in theater behind a column, you can still hear the music. The uncertainty principle is then a mathematical consequence of this wave description, or in more mathematical terms of the fact that “quantum observable do not commute”. In this sense it is not a principle in itself, but a consequence of the axioms of quantum mechanics; yet, given its historical importance in the development of quantum mechanics and the fact that it is a basic feature of quantum mechanical effects, physicists think of it as a founding principle of quantum physics. It is indeed correct that, while the observer effect gives an intuitive way to justify Heisenberg’s principle, nowadays physicists distinguish between the two, and they have been working hard to better understand their subtle differences.” -Kurzgesagt – In a Nutshell
