Novopolotsk ()

Novopolotsk is one of the youngest towns of the Byelorussian Soviet Socialist Republic. It is on the Dvina river. It came into existence as a town of chemistry. There are four large industrial enterprises here: the chemical works Polymer, the vitamin works, the measuring devices plant and the refinery. Thousands of workers work at these plants. Many of them combine work and study. The population of the town constanly increases. It is a town of young people.

The construction of Novopolotsk and its unique industrial complex became a vivid example of the great friendship of the peoples of our country. A large number of workers and specialists came here from all parts of our country.

. .

The town becomes larger from year to year. The gigantic crans all over the town are an evidence of the huge scale of construction in Novopolotsk. The town is quit modern with its beautiful five- and nine-storey buildings, numerous kindergartens, cinemas, restaurants and Palaces of Culture. It is clean and attractive with its wide streets and parks. There are many shops, a number of libraries, a local museum and some hotels.

C.F. Powell (1903-1969) ()

Powell was born in December 1903 in England. His parents were poor and they were determined to give their children a good education to increas their opportunites for a better life. In 1921 Powell won a scholarship of one of the colleges at Cambridges which he graduated in 1925 with first-class honours in science. He started his scientific career at the Cavendish laboratory headed by Ernest Rutherford. After gaining his scientific degree at Cambridge in 1928 Powell accepted a position at the new Phisics laboratory in the University of Bristol. Powell spent the rest of this career there advancing to professor in 1948 and director of the laboratory in 1964.

In 1947 Powells Bristol group identified a new particle in the cosmic radiation. Powell and other two scientist discovered the p-meson and demonstrated that this sub-nuclear particle was produced directly in nuclear reaction and rapidly decayed in flight, producing the m-meson. The discovery solved a complicated scientific problem and helped open a new era of particle physics.

For what discovery was Powell awarded the Nobel -

Prize? ?

for his development of the rhotographic method

and his meson discoveries. (2)

Outline of Soviet scientific progress ( )

The Soviet scientists have developed large-scale commercial manufacture of artificial diamonds with properties which surpass those of natural diamonds. The finest crystallographic equipment has been developed making it possible to study the atomic structure of materials.

C , . , .

The emergence of quantum electronics is one of the brightest events in the history of physics. Our scientist have suggested and developed the ideas of basiclly new sources of electro-magnetic emission-quantum generators. At present, they are used in industry for cutting and welding metals, for high precision treatment of various materials including diamonds and ceramics.

. - . , , .

The necessity to conduct extremelly fast technical calculations, primarily in atomic technique, in aviation, rocketry and cosmonautics has led to the development of fast-action electronic computers. Computers and other technical means of control are widly used in such fields as economics, planning and management of production. One should remember that the wide use of computers signifies a further advance in industry.
