Physicist Brian Cox explains quantum physics in 22 minutes
Briefly

Brian Cox emphasizes the importance of understanding quantum physics, asserting that the laws governing the subatomic world also dictate the reality we perceive. As our use of quantum technologies, like quantum computers, increases, a deeper understanding becomes crucial. Despite the historical approach of teaching quantum mechanics, with its foundational theories, there remains a lack of consensus on the interpretation of quantum reality. This ongoing debate highlights both the complexity of the subject and the necessity for continuous exploration of quantum theories.
I think it's important to say that there aren't different rules of the game in the subatomic world and the world that we observe. This world of common sense... emerging from the well-defined behavior in the subatomic world is critical to understanding our reality... we have an increasing number of quantum technologies based on this behavior.
You could argue that even today, the interpretation of what the theory... is not universally agreed upon. This reflects a significant evolution in teaching quantum mechanics, moving from historical perspectives to a focus on contemporary interpretations.
