4. INTRODUCTION:
A Planetarium is a theater built primarily for presenting educational
and entering shows about astronomy and the night sky, or for training in
celestial navigation. Portable planet aria serve education programmers
outside of the permanent installations of museums and Science Centers.
A Shore on shoreline is the fringe of land at the edge of a large body of
water, such as an ocean sea or lake.
5. GEOGRAPHICAL PLANETARIUM:
A planetarium consists essentially of a dome usually mounted on the celling of a
hall to represent the sky. A special project is used to display images of the
celestial bodies on the dome. The viewers who are seated below can see the
projected images that will appear to be very realistic.
The projector consists of various individual units for projecting the sum , the
moon the planets and the stars tapped narrations and sound effects and to the
effectiveness of the presentation.
A planetarium is a theatre built primarily for presenting educational and
entertaining shows about astronomy and the right sky , or for training in celestial
navigation.
Planet aria range in size from the Hayden planetariums 21- meter dome seating
423 people , to three-meter inflatable portable domes where children sit on the
floor. Such portable planet aria serve education programs outside of the
permanents installations of museums and science centre. The mark I projector
installed in the Detaches Museum in 1923 was the world’s first planetarium
projector. Archimedes is attributed with processing a primitive planetarium
device that could Predict the movements of the sun and the moon and the
Planets. The discovery of the Antikythera mechanism proved that such devices
already existed during antiquity.
In 1905 Oskar Von Miller of the Detaches Museum in Munich Commissioned
updated versions of a geared ornery and Planetarium from M Sinter and later
worked with Franz Meyer chief engineer at the Carl Zees optional works in Jena
on the largest mechanical planetarium ever constructed capable of displaying
both heliocentric and geocentric motion. This was displayed at the Detaches
museum in 1924, construction work laving been interrupted by the war. The
planets travelled along overhead rails, powered by electric motors: the orbit of
strum was 11:25 in diameter. 180 stars were projected into the wall by electric
bulbs.
6. SEA SHORE:
A sea shore or shoreline is the fringe of land at the edge of a large body
of water, such as an ocean sea or lake. In physical oceanography a shore
is the wider fringe that is geologicaly modified by the action of the body
of water past and present while the beach is the edge of the action of the
shore representing the interitidal zone where there in one. In contrast to
a coast a shore can border any body of water , while the coast must
border an ocean ; that is type of shore .T he word shore is often
substituted for coast where an oceanic shore is meant.
Shore are influenced by the topography of the surrounding landscape ,
as well as by water induced erosion , such as waves . The geographical
composition of rock and soil dictates the type of shore which is created.
7. CONCLUSION:
A planetarium consists essentially of a dome usually mounted on the
selling of a hall to represent the sky. A special projector is used to
display images of the celestial bodies on the dome. The viewers who are
seated below can see the projector images that will appear to be very
realistic .
A shore or shoreline is the fringe of land at the edge of a large body of
water, such as an ocean sea or lake. Shore are influenced by the topic of
the surrounding landscape as well as by the water induced erosion, such
as weaves.
