In this work, we introduce the concept of positive information into physics. We define positive information as the degree of internal order within a system and the degree of connection a system has with other systems. Negative information, as the opposite positive information, is the degree of internal disorder in a system and disconnection between systems. It corresponds to entropy in current physics theory. We show how to calculate positive information with concepts fromthe quantum theory and possibly other systems. We suggest that positive information plays a significant role in studying phenomena such as superconductivity, superfluidity, phase transitions of states of matter, the study of living systems, and more. Positive information is an important physical quantity worthy of further study.
