FIRST EDITION of the author's first major work. "Lehmann discovered liquid crystals; substances which behave mechanically as liquids but display many of the optical properties of crystalline solids. [. . .] Lehmann's early scientific interest and experimentation were concerned with electric discharges in rarified gases, but he soon turned his attention to the study of the fine structure of matter as revealed under the microscope. His first major work describing his studies was 'Molekularphysik . . .'" (DSB). References: DSB VIII, p.148. - Visit our website to see more images!
