1. Measurements.jlError propagation calculator and library for physical measurements. It supports real and complex numbers with uncertainty, arbitrary precision calculations, operations with arrays, and numerical integration.
2. Physicalconstants.jlCollection of fundamental physical constants with uncertainties. It supports arbitrary-precision constants
7. PhysicalOptics.jlA package for simulation of physical optics. Physical optics is more general than ray optics but not as general as full electrodynamics.
