Introduction

This unit discusses the future of Europe, and it looks particularly closely at what may happen to the smaller political units presently existing below the level of the nation-state. These include nation-regions like Scotland and Wales, larger entities like the German Länder, and smaller more recently created regions with less existing cultural unity. Despite the very large differences between them, for our purposes all these political entities are called ‘regions’. The un

6.2 Shaping knowledge

It seems inevitable that any understandings we have will have been shaped and influenced by other (past and present) members of the same culture(s) we belong to. Most of these influences ‘just happen’: they arise out of our experiences as part of a culture whose members have had their experiences and shared them over many centuries. However, knowledge can also be deliberately influenced by powerful elements within a society: as we saw in Section 5.3, the church suppressed Galileo's r

5.7 Summary

This section of the unit has made you aware that:

  • science is formed by a community of practice, creating knowledge and requiring a special language for its communication;

  • there is a difference between objective scientific methods and subjective ways of knowing;

  • political power influences scientific discoveries, and scientific knowledge is always socially embedded;

  • public understanding and perception of scien

5.5 How society constructs scientific thinking

To understand science, it is important that we appreciate the contexts in which discoveries are made or suppressed. We can see from the account on the previous page that human understanding of the universe has changed significantly over time. The social and political climate in which scientists work has always had a profound influence on what can and cannot be said, done, published or even postulated as worthy of further investigation. (You could undertake a similar study of the debates on hu

5.2 Scientists as a community of practice

Science has been described as involving observation, description, categorisation, investigation, experimentation and formation of theoretical explanations for naturally occurring phenomena – activities performed by scientists using scientific methods.

Jacob Bronowski (1973) said, ‘That is the essence of science: ask an impertinent question, and you are on the way to a pertinent answer’ – an apt way to put it, as with science, we set off from a starting point of curiosity an

Sergei Gukov, Quantization and Categorification, Lecture 2
Both "quantization" and "categorification" have influenced many recent developments in pure mathematics and modern mathematical physics, ranging from applications in knot theory to geometric representation theory. Yet, these deep and fundamental concepts can be explained in simple and concrete examples, which will be one of the main goals in my lectures. I will follow a "hands-on" approach, aimed at understanding explicit calculations in addition to learning the general theory. For example, we

Strawkets and Thrust
In this activity, students investigate the effect that thrust has on rocket flight. Students will make two paper rockets that they can launch themselves by blowing through a straw. These "strawkets" will differ in diameter, such that students will understand that a rocket with a smaller exit nozzle will provide a larger thrust. Students have the opportunity to compare the distances traveled by their two strawkets after predicting where they will land. Since each student will have a slightly diff
