Encyclopaedia at book fair choice of quite a few

Among the planets orbiting around the sun, earth stands third from the sun and it has four layers -- crust, mantle, outer core, and inner core.

Because of the high temperature of the inner core, at 4,000 degree Celsius, the molten outer core and mantle are assumed to help create a magnetic field that extends into the space.

This is one of many pieces of interesting information about earth that will be found in "The Encyclopaedia of the World", written in Bangla for curious readers.

Four volumes of the encyclopaedia, published by The Universal Academy, consist of information on important persons, countries, animals, and geography, and are available at stall no. 401 at the Amar Ekushey Granthamela 2016.

People look at the sky, some trying to locate the stars. But few know that the stars appearing in the sky last month would not be found in the same place this month.

"The Encyclopaedia of the World" says the stars that were in the western sky in January have travelled far west or set down, while many new stars have appeared in the eastern sky in February.

An entry in the first volume shows that the country Vanuatu, situated on the east of Australia, consists of about 80 islands covered by deep forest and mountains. About two lakh people live in the country, and 80 percent of its population depend on agriculture. Vanuatu won independence in 1980 and became a member of the United Nations in the following year. It is considered a great tourism destination.

Sifat Rahman, who teaches geography at a school, bought a copy of the encyclopaedia.

"We've learnt many things. And many of these are available on the internet. But these are put in a nice order in the encyclopaedia, and it helps," he told The Daily Star.

"Whenever I need any information, I could get it readily."

Every day the stall sells seven to eight copies of the encyclopaedia, said Rakib, a salesman.

Meanwhile, 84 new books were published at the book fair yesterday.
