Different fields of science use the term matter in different, and sometimes incompatible, ways. Some of these ways are based on loose historical meanings, from a time when there was no reason to distinguish mass and matter. As such, there is no single universally agreed scientific meaning of the word "matter". Scientifically, the term "mass" is well-defined, but "matter" is not. Sometimes in the field of physics "matter" is simply equated with particles that exhibit rest mass (i.e., that cannot travel at the speed of light), such as quarks and leptons. However, in both physics and chemistry, matter exhibits both wave-like and particle-like properties, the so-called wave–particle duality.
What term does science not have a universally-accepted scientific definition for?
matter

The links between religious and political life were vital to Rome's internal governance, diplomacy and development from kingdom, to Republic and to Empire. Post-regal politics dispersed the civil and religious authority of the kings more or less equitably among the patrician elite: kingship was replaced by two annually elected consular offices. In the early Republic, as presumably in the regal era, plebeians were excluded from high religious and civil office, and could be punished for offenses against laws of which they had no knowledge. They resorted to strikes and violence to break the oppressive patrician monopolies of high office, public priesthood, and knowledge of civil and religious law. The senate appointed Camillus as dictator to handle the emergency; he negotiated a settlement, and sanctified it by the dedication of a temple to Concordia. The religious calendars and laws were eventually made public. Plebeian tribunes were appointed, with sacrosanct status and the right of veto in legislative debate. In principle, the augural and pontifical colleges were now open to plebeians. In reality, the patrician and to a lesser extent, plebeian nobility dominated religious and civil office throughout the Republican era and beyond.
