Babbage: A bit of peace, round the corner
The end of bitcoin’s civil war and a look at new technology that can be used to see round corners
1.4 What is ethics? I'd like to introduce an idea of ethics based on the work of G. E. Moore, a Cambridge Don who died fifty years ago. Bearing in mind that concerns with ethics date back at least to the Ancient Greeks, you might not be surprised that I bring in some ideas from Moore's Principia Ethica, a text written over 100 years ago but articulated in a particularly clear and plain-speaking style. Moore's take on things is that when ‘good’ and ‘bad’ are involved, then we're in the realm of eth
16.5 The database server A database is used to store data in a form that can be organised and searched. A supermarket may use a number of different databases in order to carry out its activities. I'll now discuss two examples of database use: firstly, pricing and stock control and secondly, loyalty cards. I'll use these examples to illustrate how data is manipulated in a supermarket ICT system.

Introduction This course focuses on your initial encounters with research. It invites you to think about how perceptions of mathematics have influenced you in your prior learning, your teaching and the attitudes of learners. This OpenLearn course is an adapted extract from the Open University course ME825 Researching mathematics learning

4.4 Summary and implications
Britain was the first country to industrialise, and it acquired the largest empire ever during this same period. But its sphere of economic influence extended far beyond the boundaries of the formal British Empire. This unit focuses on the economics of empire, using a case study of one town, Dundee in eastern Scotland, to explore this huge topic.
6.637 Optical Signals, Devices, and Systems (MIT)
6.637 covers the fundamentals of optical signals and modern optical devices and systems from a practical point of view. Its goal is to help students develop a thorough understanding of the underlying physical principles such that device and system design and performance can be predicted, analyzed, and understood.
Most optical systems involve the use of one or more of the following: sources (e.g., lasers and light-emitting diodes), light modulation components (e.g., liquid-crystal light modulato
4.3 Green from the grassroots up People who demand a radical break with the business-dominated path of economic globalisation believe that the claims of the mainstream business community are at best hopelessly inadequate, and at worst deceitful. However, they know they have to come up with some answers of their own. This section outlines ideas that seek to underpin a transition to green economies owned and run at grassroots level. Sounds ambitious? Author(s):

The prerequisite requirements to gain full advantage from this course are an understanding of ordinary differential equations and basic familiarity with partial differential equations. This OpenLearn course provides a sample of level 2 study in Author(s): Lecture 11 - 1/29/2010 6.2.2 Threats and vulnerabilities A hacker who threatens your organisation's information assets is taking advantage of vulnerabilities in the media and systems which handle them. Vulnerabilities and threats clearly go hand-in-hand: each threat is directed at a vulnerability. The relationship between information assets, threats, vulnerabilities and existing defences is illustrated in Author(s): The Korean War Lecture 06 - 10/12/2010 4.6 Agency explanations: rational choice theory The work of the Chicago School, despite the potential pitfalls of participant observation, does demonstrate that if you want to know why people commit crimes it makes sense to ask them. In his memoir of a criminal career in the early twentieth century entitled Jail Journey, Jim Phelan wrote: The robber is a tradesman who, from economics or other motivation, chooses a trade with greater rewards and dangers th 1.3.1 The vertical 'structure' of the atmosphere The atmosphere is not a simple, uniform slab of absorbing material. On the contrary, it gets progressively 'thinner' or less dense with increasing altitude (height above mean sea level); i.e. the total number of molecules in a given volume of air is lower, and so is the pressure. About 80% of the total mass of the atmosphere is within some 10 km of the surface; 99.9% lies below 50 km. The important corollary is that the key greenhouse gas molecules (H2O and CO2 Inside Out
