3.3 Data and information

This course is also about information, which in Subsection 2.1 was distinguished from data. Whereas data is a discrete item like a price or the name of a product such as milk, information links two or more items of data to give knowledge: e.g. the price of milk is 50p.

To give a simple example, if I said to you that I was standing at approximately 1 degree 40 minutes and 20 seconds longitude west (written 1°40′20″W), 55 degrees, 4 minutes and 57 seconds latitude

6.3 What is the main requirement for regional government? Is it a shared identity?

If we compare the UK with other Western democracies such as Spain, Italy or Germany – all endowed with decentralised structures allowing various degrees of political autonomy for their regions – we discover that strong regional identity, as in Catalonia, the Veneto and Bavaria, is always a very important feature. However, some newly created regions such as La Rioja and Madrid in Spain also exercise devolved powers. What unites them is a common interest; the belief that regional government

1.1 Conductor–insulator–semiconductor structures

A forensic examination of the inside of any silicon chip would reveal a miniature network of metal tracks criss-crossing on several levels, separated by insulating layers of silicon dioxide and periodically stitched down to the underlying tracks and the underlying silicon. Down in the silicon proper there is an intricate pattern of islands of p-type material in pockets of n-type material and vice versa. The precision and regularity of the patterns of different materials tells of a highly soph

4.3 Decimals

A decimal number is a different way of representing numbers smaller than one. You put them after a full stop (the decimal point), for instance 0.5. The first digit after the decimal point represents tenths. If you sliced a cake into 10 slices, each slice would be a tenth of the cake.
