In the exploration of physics, Bohr emphasized that there is no singular reality that exists apart from our observations. He argued against the notion that the primary goal of physics is to discover the true nature of the universe in an objective sense.
Instead, Bohr believed that physics should focus on understanding how we can describe and interpret nature based on our experiences and measurements. This perspective highlights the importance of observation in shaping our understanding of the physical world, as discussed in Walter Isaacson's biography of Einstein.
