    "abstract": "We explore consequences of a hypothetical difference between active charges,\nwhich generate electric fields, and passive charges, which respond to them. A\nconfrontation to experiments using atoms, molecules, or macroscopic matter\nyields limits on their fractional difference at levels down to 10^-21, which at\nthe same time corresponds to an experimental confirmation of Newtons third law.",
