the art of slicing life thinner than a whisper to read its secrets
means the branch of biology concerned with the microscopic structure of tissues in plants and animals.
from From Greek histos, meaning 'web' or 'tissue' — originally the warp of a loom, the upright threads on which weaving is hung — joined to -logia, 'study of.' The 19th-century scientists who named the field saw tissue as something woven: a fabric of cells whose threads could be read under glass. So histology is, quite literally, the study of life's loom-work.
