3 Hot dry rock (HDR) fields

Heat flow through some parts of the continental crust can be well above normal locally because the underlying rocks contain abnormally high concentrations of uranium, thorium and potassium, which generate considerable heat. To add significantly to surface heat flow and thereby create high-temperature anomalies at shallow depths requires a large volume of such radioactive rocks. This condition is satisfied by some, but not all, granitic igneous intrusions, whose original magma became ch

5.5 Experiences that motivated the development of systems methods

I have already introduced various systems methods. Behind all of these methods, there has generally been a champion, a promoter aided by countless co-workers, students, etc. To paraphrase the French sociologist of technology, Bruno Latour: we are never confronted with a systems method, but with a gamut of weaker and stronger associations; thus understanding what a method is, is the same task as understanding who the people are.

A method, like any social technology, depends on many peopl

Digital Nepal
Nepal is one of the poorest countries in the world, so just how has it managed to develop a wireless network and promote innovation? This collection explores how Nepal has developed its digital technological infrastructure, how it is still developing from a complex political background and gives a sense of how different cultures around the world relate to digital technology. The videos look at the country's recent history, with particular focus on education, health, language and the economy. Th

7.3 Running the models forward

What happens when the models are run forward? It depends upon the models used and the scenarios they are asked to run. It seems almost certain, however, that there will be increases in the global mean surface temperature, to the order of +1.5 to +4.5 °C (– possibly more, according to some models and scenarios.

These changes are predicted to be associated with increases in sea level, changes to weather conditions (e.g. more regular and violent winter storms in the UK) and changes to t

4.4 An introduction to WiFi

WiFi (from 'Wireless Fidelity') is used to connect devices together in one of two network configurations known as 'ad hoc' and 'infrastructure'. We shall explain these terms shortly. (As a starting point, though, you could look up the terms 'ad hoc' and 'infrastructure' in your dictionary.)

In wireless LANs, nodes are usually referred to as stations – probably because each communicating device acts as a radio station with transmitter and receiver. These functions, and the neces

Introduction

For many of us the concept of attention may have rather negative connotations. At school we were told to pay attention, making us all too aware that it was not possible to listen to the teacher while at the same time being lost in more interesting thoughts. Neither does it seem possible to listen effectively to two different things at the same time. How many parents with young children would love to be able to do that! One could be excused for feeling that evolution has let us down by failing

12.007 Geobiology (MIT)
This course introduces the parallel evolution of life and the environment. Life processes are influenced by chemical and physical processes in the atmosphere, hydrosphere, cryosphere and the solid earth. In turn, life can influence chemical and physical processes on our planet. This course explores the concept of life as a geological agent and examines the interaction between biology and the earth system during the roughly 4 billion years since life first appeared.

1.2 Readings

In your studies of the learning courses so far, you have investigated a range of factors that may lead up to the ‘perfect storm’: a combination of interlinked environmental, social and economic crises. You have also explored your personal ecology, extending this to incorporate quality of life and environmental impact aspects. You have done this using a range of verbal, visual and mathematical models.

You have also become familiar with the fact that our mental models evolve through

1.6.2 Alerts

Online bookshops and some of the major search engines offer ‘Alerts’ services. These work by allowing you to set up a profile once you have registered on their site, and when there are items meeting your criteria you receive an email. The good thing about alerts is that you don’t have to do anything once you have set up your profile. The downside, particularly with alerts services from the search engines, is that given the extent to which internet traffic is on the increase whether new
