The bridge between quantum states and macroscopic variables.
On one hand, there is . This is the study of macroscopic systems, governed by the majestic "Four Laws." It deals with bulk properties like pressure, volume, and temperature. It is a subject of mathematical elegance and logical deduction, famously described by Einstein as the only physical theory of universal content that he was convinced would never be overthrown.
