How does Poincaré's philosophy apply to modern physics?
Consider the ongoing discussions about the fundamental nature of space and time, or the intricate weave of quantum phenomena. My emphasis on convention and the role of the observer's perspective remains relevant. We choose our geometrical systems because they are advantageous for describing the universe we perceive. The 'laws' we formulate are, in a sense, elegant ways of organizing our observations. This doesn't diminish their power or utility, but it highlights that our understanding is a construct, a harmonious arrangement of our experiences, guided by both the external world and our internal faculty for making beautiful, useful choices. The scientist studies nature because it is beautiful, after all.
