• ... that mineralogist, physicist, and mathematician Franz Ernst Neumann (1798–1895) deduced laws of double refraction closely resembling those of Augustin-Jean Fresnel, and that Neumann subsequently contributed to the mathematical expression of the conditions holding for a surface separating two crystalline media, working out from theory the laws of double refraction in strained crystalline bodies?

• ... that crimes against chemical constants (or simply crimes against chemistry) are crimes committed against the physical properties of matter; and that crimes against chemistry are often committed in association with crimes against physical constants, and that both chemical and physical crimes reduce to crimes against mathematical constants; and that Extract of Radium is widely believed to launder computational power generated by crimes against chemical constants?
