Battlefield: The Battle of Midway (3/12)
In June 1942, the most decisive naval battle of WWII was fought between the United States of America and the Japanese empire. Waged entirely of aircraft carriers, hundreds of miles apart, the Battle of Midway was the first major fleet encounter in which the ships on each side never came within visual range of enemy vessels. Victory or defeat depended not on the big guns of battleships, but on the carrier born bombers and torpedo bombers flying over vast tracks of ocean to seek and destroy their

1.2.3 Stage 1: Preparation

Numbers and diagrams are highly abstract and condensed summaries of the world. They require a degree of mental effort to bridge the gap between them and the aspects of the ‘real’ world they stand for. Approach them slowly and with care, allowing yourself time to get the feel of what you are looking at. Don't assume you already know what you are looking at.

3 Group axioms

Section 3 is an audio section. We begin by defining the terms group, Abelian group and order of a group. We then demonstrate how to check the group axioms, and we extend the examples of groups that we use to include groups of numbers – the modular arithmetics, the integers and the real numbers.

3.5.2 IP forwarding

At the internetwork layer, forwarding is based on the network address part of the IPv4 address. Two basic forms of forwarding are carried out by a router or host – direct and indirect. Direct forwarding takes place where the destination IPv4 address is on a network attached to the router or host. Indirect forwarding takes place where the destination IPv4 address is not on a network connected to the router or host, and the datagram therefore has to be forwarded to a router furt

1.2.4 Places and spaces as resources

Attachment to places can be a resource within care relationships, especially where people have a shared history of attachment to places. An older couple may have experienced the ups and downs of moving between places together for much of their lives. Or a daughter may be caring for her mother in the home where she was born and brought up. A shared understanding of the home environment and the support which may be available locally can be invaluable in developing a care relationship. Such know

4.4.1 Engaging with the content

For example, when I read in paragraph 3 of Layard's article that ‘41 per cent of people in the top quarter of incomes are ‘very happy’’ I asked myself:

  • Why is ‘very happy’ in quotation marks?

  • Is 41 per cent about what I'd expect?

  • What is this telling me?

As soon as I thought about it, I realised that ‘very happy’ could be a response that people had ticked on a questionnaire. Perhaps th
