Copernics, like the Copernicus node on Lua, are named after Nicolaus Copernicus: the Renaissance astronomer and mathematician who proposed a heliocentric model of the Solar System in his 1543 work “De revolutionibus orbium coelestium”. Albrecht’s diary entries and the ending of the New War quest both suggest the Sun’s importance to Orokin life, science and anxieties – cultural heliocentrism, if you will.
Kesslers refer to the astrophysicist Donald J. Kessler, or the “Kessler syndrome” that he proposed in 1978: simply put, it is a scenario in which collisions between objects in orbit causes debris, which causes further collisions, and so on; this would, in turn, make successful launches into the affected planet’s orbit or beyond it even harder as the debris field intensifies. With this in mind, the resource is likely used to navigate through the Kessler-style debris fields of the (post-)Orokin era.
Fresnels are named after the French physicist Augustin-Jean Fresnel, or the Fresnel lens that bears his name: just as a Fresnel lens focusses light into a beam, so the resource of that name may focus energy into a form capable of tearing through space. Perhaps the wave-particle properties of light are involved? (Disclaimer: I am not a physicist.)
Dirac refers to the English physicist and early quantum theorist Paul Adrien Maurice Dirac. Several concepts in particle physics and quantum mechanics also bear his name, such as the “Dirac equation” (which predicted the existence of antimatter), “Dirac membrane”, and “Dirac sea”.
As a final note, all of these resources named after real scientists – one of whom, Kessler, is still alive as of writing – were removed in the same update. In addition, all of them save Dirac are explicitly Orokin in origin.
