Man will conquer space: part three

Model
Video

Abstract

In this third in a series of programs on space exploration, Dr. Wernher von Braun, rocket expert, explains and demonstrates a three-stage rocket and its role in the construction of a three-story space station, which will be a launch pad for trips to the moon. He shows viewers both a prototype space station model and moon rocket model and an animated version of the workings of the two.

News from the sky

Abstract

Explorations of the upper atmosphere are made through telemetering or the measuring of remote objects from afar. Rockets take these measuring devices into the upper atmosphere to measure cosmic ray intensity, fuel consumption, oil pressure, air speed, altitude, and the magnitude of the earth's magnetic field. Receivers on earth will retrieve the measurements transmitted from space through a radio link. Current uses of this information aid in the development of guided missiles.

Can machines think?

Model
Video

Abstract

This program discusses the scientific and business uses of computers, such as calculating 1950 census data for the U. S. Bureau of Census. It also shows the assembly of UNIVAC (universal automatic computer) at the Remington Rand plant. Dr. John W. Mauchly explains and demonstrates how a computer works, including creation of the magnetic tapes that give instruction to a computer. The program concludes that no, a computer cannot think.

The story of a parchment

Model
Video

Abstract

This program tells the story of the Declaration of Independence and U.S. Constitution, the men who drafted the document, the printing of it, and its travels between states under adverse conditions, including its transference to Fort Knox during World War II. Finally, Dr. Herbert Putnam, Librarian of Congress, asked for construction of a display case. On Constitution Day, September 17, 1951, the Constitution and Declaration of Independence were finally sealed in helium in an airtight glass envelope. Film clips show the ceremony and speakers, including President Harry S. Truman, Senator Theodore F. Green of Rhode Island, Chief Justice Fred M. Vincent, and Rev. Frederick Brown Harris, chaplain of Congress. The National Bureau of Standards developed the method for preservation after researching conditions promoting deterioration of parchment, and a reconstruction of their preservation process is explained.

How clean is clean

Model
Video

Abstract

Soaps are made from fats and alkali, which forms glycerine. Detergents when mixed with water can attack dirt and separate the dirt from soiled fabrics. Hard water, which has higher concentrations of calcium and magnesium, requires stronger detergents than regular soap for proper cleaning. It is necessary to match the detergent with the hardness of water.

Stories in stone

Model
Video

Abstract

A narrated film that shows how running water has changed the surface of the earth more than any other natural element and offers as examples the Grand Canyon (and how it was formed) and Niagara Falls (and why it is moving upstream). The film continues with glaciers as another land-molding force, explaining where they were and how they work to change the landscape. A prime example is the Yosemite Valley formation including its Bridal Veil Falls, Upper and Lower Yosemite Falls, and other natural formations. The geysers, steam vents, and hot water basins at Yellowstone National Park are also featured, including a model showing how geysers function. Water also causes erosion resulting in natural bridges such as Natural Bridge in Virginia and the Kachina, Owachoma, and Sipapu Bridges, known collectively by the Paiute Indians as "ma-vah-talk-tump," or "under the horse's belly," in the Four Corners area of the U.S. The program continues with a filmed sequences of caves, explaining how the Mammouth Cave in Kentucky and Carlsbad Caverns in New Mexico were formed.

Naval research today

Video

Abstract

Admiral Bolster discusses the U.S. Navy's research and development programs for weapons, equipment, techniques for use, and personnel training. Dr. Hulbert describes the Naval Research Lab, established in 1923 to meet the scientific and technical needs of the navy. Its departments include chemistry, mechanics, optics, radio, metallurgy, sound nucleonics, radiation, electricity, and systems coordination. One of its specific programs is the radio telescope, shown on a film. Dr. Chapanis discusses how industrial design improves the accuracy and functionality of machines for humans. Using a mock-up of a radar indicator, he redesigns it to reduce user fatigue, allow the operator to sit or stand, facilitate readings, simplify controls, and clarify codings. Dr. Mead explains the tests featured in a film showing naval systems coordination, the integration of men and equipment and how well both perform under stress. In conclusion, Mr. Poole defines a system analyst.

How to lead your dog's life

Model
Video

Abstract

Dogs can be taught to modify their behavior to fit well into their owner's lives. Dogs can be conditioned not to jump on people by body twisting, and be taught not to bark by holding their mouths shut momentarily. House breaking can begin when puppies are about three months old. The sense of place for elimination should be emphasized over negative reinforcement. Methods are shown on how to call, praise, and discipline dogs, and keep them from chewing on objects.

What do you know about wood?

Model
Video

Abstract

Mr. Dillehunt describes the versatility of wood's thickness, color, pliability, and hardness. He demonstrates the difference in hardness by driving nails into a piece of balsa wood and a piece of lignum vitae. He shows the cross-section of growth rings in a tree and the magnification of wood cells, indicating the fiber walls of wood which carry water and which shrink and often crack from lack of moisture. A model of the slash cut and the quarter cut shows the differences in lumbering wood. Mr. Dillehunt exhibits samples of ebony, curly maple and birdseye maple, used ornamentally. He also displays a bowl made from a burl, a disease of the tree. Mr. Poole recommends "Wood handbook", a guide for woodworkers produced by the U.S. Government Printing Office.
