The Paemani were a small Belgic-Germanic tribe dwelling in Gallia Belgica during the Iron Age. Their ethnic identity remains uncertain. Caesar described them as part of the Germani Cisrhenani, but a number of scholars have argued that their name may be of Celtic origin. Like other Germani Cisrhenani tribes, it is possible that their old Germanic endonym came to be abandoned after a tribal reorganization, that they received their names from their Celtic neighbours, or else that they were fully or partially assimilated to Celtic culture at the time of the Roman invasion of the region in 57 BC.

Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law of physics that calculates the amount of force between two electrically charged particles at rest. This electric force is conventionally called the electrostatic force or Coulomb force. Although the law was known earlier, it was first published in 1785 by French physicist Charles-Augustin de Coulomb. Coulomb's law was essential to the development of the theory of electromagnetism and maybe even its starting point, as it allowed meaningful discussions of the amount of electric charge in a particle.
