=Animals in space.=

In _may 1959_, the United States sent a pair of monkeys, Able and Baker, into space on a Jupiter missile. They were the first living creatures to be successfully recovered after a trip into space. Although Able died in June 1959, monkey Baker survived until ___1984____. Later in__ _1959_ and in early 1960, there were further experiments involving a pair of monkeys named Sam and Miss Sam.

Soviet scientists decided against using monkeys for test flights. Their scientific research – published in September 1958, suggested the monkeys would have to be anaesthetized and the anaesthetic would interfere with test results.

They had already launched a dog, Laika, into space in ___november 1957___. At the time, Russian scientists claimed the dog had survived a week in orbit but later reports show it died shortly after take-off from overheating and panic.

But it was the Russians who won the race to launch the first man into space. Major Yuri Alexeyevich Gagarin orbited the earth for nearly two hours on __12 april 1961____.

=James Watt= James Watt was born in Greenock on 18 January 1736. His father was a prosperous shipwright. Watt initially worked as a maker of mathematical instruments but soon began to become interested in steam engines.

The first working steam engine had been patented in 1698 and by the time of Watt's birth, Newcomen engines were pumping water from mines all over the country.

In around 1764 Watt was given a model Newcomen engine to repair. He realised that it was hopelessly inefficient and began to work to improve the design.

He designed a separate condensing chamber for the steam engine that prevented enormous losses of steam. His first patent in 1769 covered this device and other improvements on Newcomen's engine.

Watt's partner and backer was the inventor John Roebuck. In 1775, Roebuck's interest was taken over by Matthew Boulton who owned an engineering works in Birmingham. Together he and Watt began to manufacture steam engines. Boulton & Watt became the most important engineering firm in the country, meeting considerable demand. Initially this came from Cornish mine owners, but extended to paper, flour, cotton and iron mills, as well as distilleries, canals and waterworks. In 1785, Watt and Boulton were elected fellows of the Royal Society.

By 1790 Watt was a wealthy man and in 1800 he retired and devoted himself entirely to research work. He patented several other important inventions including the rotary engine, the double-action engine and the steam indicator, which records the steam pressure inside the engine.

Watt died on 19 August 1819. A unit of measurement of electrical and mechanical power - the watt - is named in his honour.
