| Perhaps to oversimplify, chemistry is derived from the very fundamental laws of physics, namely the characteristics of the electron, atom, molecule, and so forth. The life sciences are also governed by the laws of physics. In a nutshell, physics is the study of how the universe works, the very basic laws that can be applied to life sciences, physical sciences, etc. Each branch extends almost ad infinitum it seems like. Could we qualify or quantify on a whole which one(s) is the most difficult? Maybe. Any doctoral/advanced level sciences require incredibly intelligent minds, but it seems to be especially the case for mathematics and physics, not to take away from the life sciences. I just don't have much of an interest in them, though. |
