Playfair Cycle
William Playfair (22 September 1759 – 11 February 1823), a Scottish engineer and political economist, served as a secret agent on behalf of Great Britain during its war with France. The founder of graphical methods of statistics, Playfair invented several types of diagrams: in 1786 the line, area and bar chart of economic data, and in 1801 the pie chart and circle graph, used to show part-whole relations. As a secret agent, Playfair reported on the French Revolution and organized a clandestine counterfeiting operation in 1793 to collapse the French currency.

Forfarshire
Angus ( sco, Angus; gd, Aonghas) is one of the 32 local government council areas of Scotland, a registration county and a lieutenancy area. The council area borders Aberdeenshire, Dundee City and Perth and Kinross. Main industries include agriculture and fishing. Global pharmaceuticals company GSK has a significant presence in Montrose in the north of the county. Angus was historically a province, and later a sheriffdom and county (known officially as Forfarshire from the 18th century until 1928), bordering Kincardineshire to the north-east, Aberdeenshire to the north and Perthshire to the west; southwards it faced Fife across the Firth of Tay; these remain the borders of Angus, minus Dundee which now forms its own small separate council area.

Dundee
Dundee (; sco, Dundee; gd, Dùn Dè or ) is Scotland's fourth-largest city and the 51st-most-populous built-up area in the United Kingdom. The mid-year population estimate for 2016 was , giving Dundee a population density of 2,478/km2 or 6,420/sq mi, the second-highest in Scotland. It lies within the eastern central Lowlands on the north bank of the Firth of Tay, which feeds into the North Sea. Under the name of Dundee City, it forms one of the 32 council areas used for local government in Scotland. Within the boundaries of the historic county of Angus, the city developed into a burgh in the late 12th century and established itself as an important east coast trading port.

Joseph Priestley
Joseph Priestley (; 24 March 1733 – 6 February 1804) was an English chemist, natural philosopher, separatist theologian, grammarian, multi-subject educator, and liberal political theorist. He published over 150 works, and conducted experiments in electricity and other areas of science. He was a close friend of, and worked in close association with Benjamin Franklin involving electricity experiments. Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. Prie ...

Ohio River
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois.

Storming Of The Bastille
The Storming of the Bastille (french: Prise de la Bastille ) occurred in Paris, France, on 14 July 1789, when revolutionary insurgents stormed and seized control of the medieval armoury, fortress, and political prison known as the Bastille. At the time, the Bastille represented royal authority in the centre of Paris. The prison contained only seven inmates at the time of its storming, but was seen by the revolutionaries as a symbol of the monarchy's abuse of power; its fall was the flashpoint of the French Revolution. In France, 14 July is a national holiday, usually called Bastille Day in English. However, the expression Bastille Day is properly incorrect, as the event celebrated during the national holiday is the Fête de la Fédération of 1790, which was itself the 1st anniversary of the Bastille Day. Background During the reign of Louis XVI France faced a major economic crisis. This crisis was caused in part by the cost of intervening in the American Revolution and exacer ...

Boulton & Watt was an early British engineering and manufacturing firm in the business of designing and making marine and stationary steam engines. Founded in the English West Midlands around Birmingham in 1775 as a partnership between the English manufacturer Matthew Boulton and the Scottish engineer James Watt, the firm had a major role in the Industrial Revolution and grew to be a major producer of steam engines in the 19th century. The engine partnership The partnership was formed in 1775 to exploit Watt's patent for a steam engine with a separate condenser. This made much more efficient use of its fuel than the older Newcomen engine. Initially the business was based at the Soho Manufactory near Boulton's Soho House on the southern edge of the then-rural parish of Handsworth. However most of the components for their engines were made by others, for example the cylinders by John Wilkinson. In 1795, they began to make steam engines themselves at their Soho Foundry in ...
