 Davy's Poem Seeking to Inspire Other Scientists

He depicts himself watching in rapture the two adult grey-tailed eagles in the bright sunlight, followed by their young offspring. This moment is transformed into an image of Davy the man of science, hoping to inspire his young scientific protégés to ever greater discoveries. The mighty birds still upward rose In slow but constant and most steady flight. The young ones following; and they would pause, As if to teach them how to bear the light And keep the solar glory full in sight. So went...

 The Rhythms of Nature

Nature vibrates with rhythms, climatic and diastrophic, those finding stratigraphic expression ranging in period from the rapid oscillation of surface waters, recorded in ripple-mark, to those long-deferred stirrings of the deep imprisoned titans which have divided earth history into periods and eras. The flight of time is measured by the weaving of composite rhythms- day and night, calm and storm, summer and winter, birth and death such as these are sensed in the brief life of man. But the c...

We now know that this common ancestor was a dinosaur. Its overall appearance would give few clues that it was indeed a “missing link”—that one lineage of descendants would later give rise to all modern birds, and the other to more dinosaurs. Truly birdlike traits, such as wings and a large breastbone for anchoring ...
