Housed appropriately in a setting typical of twentieth-century ingenuity
and accomplishment, the museum is a focal point of interest for scientifi-
cally curious adults and a wonderland for children. It is known also as
the Hall of Motion because its thousands of models, replicas, dioramas,
working demonstrations, and visitor-operated machines dramatize the scien-
tific achievements and industrial developments of the machine age; motion
pictures, lectures, and conducted tours supplement these graphic illustra-
tions of simple and complex mechanisms of the past and the present. The
museum is visited annually by half a million people.

Approximately twenty-five hundred permanent displays and a constantly
changing series of exhibitions—lent by notable research laboratories, gov-
ernment agencies, and industrial organizations—inform the visitor of the
latest inventions, discoveries, and scientific developments. Included in the
series of temporary exhibits have been zoning models and unified city
planning designs of the New York City Housing Authority, graphic sur-
veys of the work of the Rural Electrification Administration and the Ten-
nessee Valley Authority, a collection of X-ray plates and photographs indi-
cating the progressive steps in a brain operation, "Better Things for Better
Living Through Chemistry," "Modern Plastics," "Steels of Today and To-
morrow," and "The Story of Man."

Permanent exhibits are grouped under the general classifications of tex-
tiles, shelter, food industries, power, aviation, communication, machine
tools, highway, railroad and marine transportation, and electro-technology.
Several hundred machines both in model form and actual size are either in
continuous operation or may be put in motion at will; the visitor may op-
erate an electric generator, a telautograph, a model locomotive, a power
plant, an ocean depth finder, or a radio direction finder. Especially attrac-
tive is the experience of handling the controls of an actual airplane.

The 112 examples of sectional machine parts, mounted on the semicircu-
lar wall of the main rotunda, are popular features of the museum, for they
afford thrilling discovery of machine operations usually hidden from view.
