The history of the calculator

Ever since recorded mathematics began, people have been making use of mathematical aids. Four thousand years ago, Babylonian scribes were consulting mathematical tables which included multiplication tables, tables of squares and square roots, and tables of reciprocals of numbers. These values were recorded as marks on clay tablets that were then baked hard in the sun—and some have survived to the present day. (There are several originals to be seen in the British Museum.)

Following the Scottish Parliament elections in May 2007, the balance of power and system of government in Scotland has changed significantly, giving rise to Scotland's first minority government, led by the Scottish National Party.

The first three courses in this section consider issues of nationalism, political devolution and the role of nation-regions in the European Union. The final two courses consider social issues such as geographical identity and poverty in Scotland.
