This might be a naive question but how does one determine what "best" is for multiple subjects?
Even in your example, physics and mathematics could be curated for "best" when dealing with equations and foundational knowledge that has been hardened over decades. For history, climate change of invasion of Ukraine, isn't that sensitive to bias, manipulation and interpretation? These are not exact sciences.
