Thomas Andrews – hinnat ja saatavuus

This classic historical biography tells the tale of the brilliant shipbuilder who built the Titanic only to perish on his creation during its sinking in April, 1912. Andrews was born in Belfast, Ireland, where his father was a linen merchant. He attended the Belfast Academy and the Royal Belfast Academical Institution, where at the latter of which he studied mathematics under James Thomson. In 1828 he went to the University of Glasgow to study chemistry under Professor Thomas Thomson, then studied at Trinity College, Dublin, where he gained distinction in classics as well as in science. Finally, at University of Edinburgh in 1835, he was awarded a doctorate in medicine. Andrews began a successful medical practice in his native Belfast in 1835, also giving instruction in chemistry at the Academical Institution. In 1845 he was appointed vice-president of the newly established Queen's University of Belfast, and professor of chemistry there. He held these two offices until his retirement in 1879 at age 66. He died in 1885, and was buried in the Borough Cemetery in Belfast. In 1842, Andrews married Jane Hardie Walker (1818-1899). They had six children, including the geologist Mary Andrews Andrews first became known as a scientific investigator with his work on the heat developed in chemical actions, for which the Royal Society awarded him a Royal Medal in 1844. Another important investigation, undertaken in collaboration with Peter Guthrie Tait, was devoted to ozone. His reputation mainly rests on his work with liquefaction of gases. In the 1860s he carried out a very complete inquiry into the gas laws-expressing the relations of pressure, temperature, and volume in carbon dioxide. In particular, he established the concepts of critical temperature and critical pressure, showing that a substance passes from vapor to liquid state without any breach of continuity. In Andrews' experiments on phase transitions, he showed that carbon dioxide may be carried from any of the states we usually call liquid to any of those we usually call gas, without losing homogeneity. The mathematical physicist Willard Gibbs cited these results in support of the Gibbs free energy equation. They also set off a race among researchers to liquify various other gases. In 1877-78 Louis Paul Cailletet was the first to liquefy oxygen and nitrogen.
