We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
No. 13-18 Heavenly Bodies
A Study of Astronomy
Ao. 13 The Development of Astronomical Knowledge
The Chaldeans, studying the heavens from the top of one of their temple-towers, are seen first; then the earth known to the Greeks, a disc surrounded by the ocean. The data whereby man first suspected the roundness of the earth is pictured. Diagrams explain
the Ptolemaic theory of Epicycles.
Scenes from the lives of Copernicus, Kepler, the discoverer of the telescope and of
Galileo are shown while the discoveries
of each are covered in detail.
Ao. 14 '■ Gravitation — The Moon—
-Constellations
Newton is pictured working on his Law of Gravitation. Numerous diagrams explain his theory and its application to the problem of the orbits of the planets.
Pictures of an incoming tide and diagrams disclosing the part played by the moon give a concrete example of the attraction of
gravity.
A series of scenes explain the recurring phases of the moon.
On a star-map of the heavens the constellations of the Big and Little Dipper, Cassiopeia, Andromeda, Lyra, Cygnaus, Perseus and Auiga are successively outlined.
Ao. 15 The Sun — Its Influence on the Earth
A thorough study of the sun is presented in a series of unusual episodes.
The nature of the sun is first investigated. Its spots and their effects, the causes of an eclipse, the corona seen at that time, solar prominences — all these are shown.
As if from off in space we see through the eye of the camera the influences of the sun on the globe. In a series of scenes we study the reasons for day and night, the differences in local times, the zones and the seasons.

ISo. 16 Mercury — Venus — Mars
The machine of which many men have dreamed, leaves the earth for a trip through space.
The travelers witness sunrise and sunset on the moon with the earth in the distance. They explore the scorched and frozen sides
of Mercury, then circle near cloud-covered Venus.
As the machine nears Mars one of the polar caps melts and the “canals” become increasingly distinct. The machine lands and as the travelers climb out the}' discover the lessened force of gravity on Mars.
