Introduction

Whether we are aware of it or not, we are surrounded by networks through which information flows constantly. Our notions of time and location are changing – the world seems to have become a 'global village' where distance is no longer a barrier to commercial or social contact. If we live in Britain or other parts of the westernised world, it's difficult to imagine being without all the networked infrastructure that plays a crucial part in our daily lives. This free course, IT in everyday

3 Photovoltaic conversion of solar energy

You have probably used direct conversion of solar energy to electricity though a solar cell that powers a pocket calculator or a solar 'trickle' charger to top up car batteries. Both exploit the photovoltaic (PV) effect, first described in 1839 by Edmond Becquerel. He observed that the voltage of an early 'wet cell' battery increased when its silver plates were exposed to light. In 1877 Cambridge physicists discovered that selenium crystals created an electrical current when exposed to

6.4 Does one community seceding grant a similar right to others?

Consider the position of community C. If B secedes, it takes C with it into the new state. But does C then have the same right to secede from B? Consider the case of Quebec. Quebecois separatists have come very close to achieving the bare majority needed to achieve their goal. But if they gained the right to secede from Canada, would other groups who do not see themselves as a part of a francophone entity likewise have the right to a further independence vote for themselves?
