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 Cambridge's 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 Physics 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 1964.1903., , . 1921, 19251928, 1948 1964. In 1947 Powell's Bristol group identified a new particle in the cosmic radiation.

Powell and other two scientist discovered the -meson and demonstrated that this sub-nuclear particle was produced directly in nuclear reaction and rapidly decayed in flight, producing the -meson. The discovery solved a complicated scientific problem and helped open a new era of particle physics. 1947, -... 5...

6. (2, 3 4-). 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 basically 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 extremely 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 widely 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., , ., . 6... What did Sergey Korolev say about the aims of - space programme... conquering outer space. (3)... No 2 10: . 9-91: 1999...
