What is the Coccyx?

-
The coccyx is the last part of the spinal column of man and consists of four nodules of bone-like small vertebrae and corresponds to the tail found in lower animals. The bones are deeply buried in muscle tissue, but sometimes they jut backwards and are surrounded by a fold of skin so as to form an actual tail. The name coccyx was given by the Greek physician Galen (130-200 AD) and comes from the Greek word for cuckoo; as the bone more or less resembles a cuckoo's bill.

When were the First Mechanical Clocks Made?

-
Image
The first mechanical clocks are believed to have been made in China in 1088 AD. Later in 1200s, they were first made in Europe. Such clocks made in Europe were driven by a weight on the end of a cord wound round a drum. As the drum rotated, it turned the hands of the clock. The earliest known clock was made in Spain in 1276 AD and the oldest mechanical clock that still works is in Salisbury cathedral in Britain. It was made in 1368. These clocks had devices called escapements to keep the hands turning at the correct rate, so that the clocks depicted the correct time.

Why does Mistletoe Grow on Trees?

-
Image
M istletoe is a plant which grows on branches of higher trees. It is a partial parasite since it has green leaves containing chlorophyll and can make its own food by photosynthesis. It takes the water and minerals it needs from the sapwood of the host tree. It is found growing on trees like apple, hawthorn, willow, poplar and lime . The seeds of mistletoe are spread by birds and once the seed germinates on the host tree, it develops haustorium . The haustorium is a tough structure and ensures of a regular supply of water and nutrients from the sapwood of the host to the mistletoe. The plant then develops a clamp like structure on the tree to be placed firmly.

How do Trawlers Fish?

-
Image
T rawlers are vessels that fish with a large net called trawl. The trawl is a bag-like net and could be over 100 metres long. It is attached to the rear part of the vessel with long ropes, which can go down to enormous depths upto 1500 metres or more. The fish are swept in at the wide, open end and then get trapped at the narrower closed end. When the net is full of fish, powered winches bring it back to the vessel. Modern trawlers are big factories in themselves . The fish are automatically gutted, filleted and frozen there on board .

Comet

C omet A small Solar System body made of ice and dust. Comets are asteroidal in appearance at distances of many astronomical units from the Sun (when they consist of a bare , inactive nucleus), and are often spectacularly active when nearer to the Sun. The characteristic bright head (coma ) and streaming tails (both dust and ions) are created by solar heating, with emission of light from gas molecules and scattered light from the dust. The comet nucleus is a few km in size, irregularly shaped and very dark ; dust in the coma contains carbon and silica; there is evidence of polymerized organic molecules; the gases of the coma include water, carbon monoxide, carbon dioxide, ammonia, methane, and hydrocarbons. The source of comets is believed to be a spherical halo cloud about the Sun called the Oort Cloud. Observable comets are occasionally scattered into the inner Solar System by the gravitational fields of nearby stars and giant molecular clouds. Some ( eg Halley's comet) are...

Communism

C ommunism A political ideology which has as its central principle the communal ownership of all property, and thereby the abolition of private property. Modern communism is specifically associated with the theories of Karl Marx , who saw the emergence of a communist society as being the final stage in a historical process that was rooted in human material needs, preceded by feudalism, capitalism , and (a transitional stage) socialism. Communism, according to Marx, would abolish class distinctions and end the exploitation of the masses inherent in the capitalism system. The working class, or proletariat, would be the instrument of a revolution that would overthrow the capitalist system and liberate human potential. The Communist Party of the Soviet Union (CPSU), first of all under Lenin's leadership and followed by Stalin, reinterpreted Marxist ideology as Marxism-Leninism-Stalinism, the major feature of which is democratic centralism. The CPSU provided the ideological lead for ...
