Summary:
Delineates interesting facets of the development of our decimal system. Compares the additive, subtractive, multiplicative, and positional notation aspects of the Chinese, Babylonian, Egyptian, and Hindu-Arabic systems. Uses models to explain concepts which lead to greater understanding of base 10 systems.

Compares two dairy farms--one in Southeastern Wisconsin and the other in Central New York State. Shows the land use and cultural practices which reflect adaptation to such elements of the physical environment as topography, soil, precipitation, temperature, and length of growing season. Describes such man-made conditions that influence the marketing of milk as the proximity of farms to urban areas, sanitation requirements, and transportation and refrigeration facilities.
Discusses the life of Durer and the pivotal point he represented in connecting the artistic development of Italy and Northern Europe. Presents examples of his work that show his passage from the Middle Ages to the Renaissance. Develops the idea that through a study of his work the fusing of his Gothic inheritance and the organic Renaissance can be observed.

What happens when a rocket ship in space is struck and damaged by a meteor? Capt. Gell, a Navy expert on crew equipment, demonstrates the Navy’s full-pressure space suit for emergency escape from a shattered craft. Dr. Haber, an aerodynamic engineer who has made a thorough study of the theoretical problems of escape and survival far out in pace, explains the difficulty of making an individual descent into the atmosphere, on one hand, and of rescuing the stranded flyer in space, on the other. Dr. Herbert’s recommendation: the crew should ride the damaged vehicle back to earth --if anything remains of it.
Portrays the role of developmental genetics in dealing with ways phenotypes come into being through the action of genes. Presents a complete discussion of the Creeper domestic fowl--its genetic basis, morphology, embryological history, and the experimental work that led to an understanding of how this gene affects early development to produce the morphological features seen as the outcome of the developmental process. Lecture given by Dr. L. C. Dunn.
Describes the ways in which genes produce phenotypic differences by acting very early in embryonic development. Shows that this action may take place at a distance through chemical messengers (pituitary dwarfism in the house mouse, lethal giant larva in Drosophila), or it may involve tissue induction systems (Brachyury and taillessness in the house mouse). Discusses the development of eye color in Drosophila as a model of how each of the steps in a chain of chemical processes leading to development is under genic control. Lecture given by Dr. L. C. Dunn.

Summary:
Uses a combination of animation and live-action photography to logically develop the formulas for determining the volume of pyramids, cones, and spheres. After reviewing the formulas for the volumes of prisms and cylinders, the volume of a pyramid with a rectangular base is determined. This is then related to pyramids with non-rectangular bases and cones, the volume of the latter being compared to a cylinder. Defines a sphere and portrays a method of determining its volume. Concludes with commercial and industrial applications of these formulas.
Wind, heat, cold, and rain combine to weather the rocks and break them down. But the face of our earth is molded and the decayed rock carried away from one place and deposited in another mainly by water. The deposits laid down by water, wind, or ice produce after long periods of time and under pressure, rocks which are classed as sedimentary. You will see and learn how to distinguish some of the common sedimentary rocks; limestone, sandstone, shale, and conglomerate. Each of these sedimentary rocks is formed in a different way; limestone by chemical precipitations, sandstone by grains of sand cemented together, shale from beds of mud or clay pressed and cemented into thin layers, and conglomerate is made of gravel or pebbles of assorted sizes cemented together. You will be introduced to one of the most interesting features of sedimentary rocks -their fossils. These records of living things are guides to the history of life on the earth.

There are many partnerships in nature where two plants may help each other, or a plant and animal may mutually benefit one another, or where two animals may contribute to each other’s welfare. You will see on this program an example of each. The lichen, a common plant, looks like one individual, but really consists of two kinds of plants living together. You will see this story through the microscope. And you will see the story of cross-pollination, in which bees and insects take nectar from the flowers and in so doing transfer pollen from one flower to another. Ever look inside a wood eating termite? You will and with a microscope to see a story of mutual benefit. Inside the termite lives a host of one-celled animals which assist the termite in digesting the cellulose in the wood he consumes. (WGBH-TV) Kinescope.
