    Epigraphy is the study of inscriptions or epigraphs as writing. It is the science of identifying graphemes, clarifying their meanings, classifying their uses according to dates and cultural contexts, and drawing conclusions about the writing and the writers. A person using the methods of epigraphy is called an epigrapher or epigraphist.

    Lux meters, also known as light meters, measure the intensity of light as perceived by the human eye with the help of photo detectors.The lux is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. In photometry, it is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.

    Myrmecology is a branch of entomology focusing on the scientific study of ants. The word myrmecology was coined by William Morton Wheeler (1865–1937). The earliest scientific thinking based on observation of ant life was that of Auguste Forel (1848–1931)
