Cytology Quotes (5 quotes)

Modern cytological work involves an intricacy of detail, the significance of which can be appreciated by the specialist alone; but Miss Stevens had a share in a discovery of importance, and her work will be remembered for this, when the minutiae of detailed investigations that she carried out have become incorporated in the general body of the subject.
In obituary, 'The Scientific Work of Miss N.M. Steves', Science (11 Oct 1912), 36, No. 928, 468.

The geneticist to-day is in a rather difficult position. He must have at least a bowing acquaintance with anatomy, cytology, and mathematics. He must dabble in taxonomy, physics, and even psychology.
In 'The Biochemistry of the Individual' (1937), collected in Neurath Hans (ed.), Perspectives in Biochemistry (1989), 6.

The microscope has shown me that all the varied forms in the animal tissues are nothing but transformed cells. All my work has authorized me to apply to animals as to plants the doctrine of the individuality of the cells.
From his preliminary announcement (1838). As quoted in William Dobinson Halliburton, A Textbook of Chemical Physiology and Pathology (1891) 186.

The whole organism subsists only by means of the reciprocal action of the single elementary parts.
In Theodor Schwann and Henry Smith (trans.), 'Theory of the Cells', Microscopical Researches Into the Accordance in the Structure and Growth of Animals and Plants (1839, 1847), 191.

[Beyond natural history] Other biological sciences take up the study at other levels of organization: dissecting the individual into organs and tissues and seeing how these work together, as in physiology; reaching down still further to the level of cells, as in cytology; and reaching the final biological level with the study of living molecules and their interactions, as in biochemistry. No one of these levels can be considered as more important than any other.
In The Nature of Natural History (1961, 2014), 7.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
