And what do quanta and cosmology have in common  Energy  To simply categorize physics as the study of everything is imperceptive  When modeling sand falling into a pile or nuts sorting in a jar a physicist doesnt really care about the identity of the particles at hand just certain bulk properties that relate to its energetics  The chemist tries to understand how the material composition in turn generates those energetic qualities but then usually isnt capable of formulating the dynamic description of what happens when its shaken or spilled  A physicst usually could care less about why niobium is better for a collider than copper just that it is  And chemists dont just care about chemical elements and compounds there is a whole field of chemistry dedicated to monitoring interactions of nuclei with nucleons nuclear chemistry  still matter  As a point of culture chemists tend to focus on the diversity of matter and how that affects interactions with energy and physicists focus on the unity of energy and how that affects matter  Physical chemists very nicely bridge this  they put quite a bit of energetics while still caring deeply about the identity of that which is being studied  While the duality may sound a bit contrived there is definitely some truth to the statements and while not perfect its more meaningful than whats there now
