Transport in the Low Carbon Age
Minerva lecture on 21 February given by Professor James Turner for the Minerva Series. Society has become used to the fact that personal transportation is really affordable. Over the past 130 years this situation has arisen with no stimulus from government because of the favourable economics that have evolved. However, the use of fossil fuels to power transportation rightly means that action has to be taken if we are to avoid climate change. The lecture discusses the scale of the challenge, som

2.3.4 Geophysical methods — borehole logging

If a core is not recovered from a borehole, another way to assess the types of rock that it penetrates is to measure their physical properties. Mounting a string of electronic instruments behind the drill bit most conveniently does this: it allows the properties of the rock to be monitored as the borehole is drilled. An alternative is to lower instruments down the completed borehole by cable; hence the name wireline logging.

Such logging measures several physical properties of th

12.1 Localisation of sound in the horizontal plane

While information about frequency and intensity is essential for interpreting sounds in our environment, sound localisation can be of critical importance for survival. For example, if you carelessly cross the street, your localisation of a car's horn may be all that saves you. Our current understanding of the mechanisms underlying sound localisation suggests that we use different techniques for locating sources in the horizontal plane and vertical plane.

4.1 Global coal reserves

Having looked in detail at how coal is mined, this section focuses on those areas of the world that produce it. It begins by looking at how and why reserves of coal are distributed throughout the UK and Europe, before reviewing the current global reserves of coal.

1 Overview

Even in images taken with the most modern equipment on a large telescope, it can be difficult to pick out the galaxies now known as 'active' from the other more normal galaxies. But if your telescope were equipped to examine the spectra of the galaxies, then the active galaxies would stand out. Normal galaxies contain stars that are generally similar to those in our own Galaxy; and spiral galaxies have additional similarities to the Milky Way in their gas and dust content. Active galax

1.1 What is the carbon footprint and why is it important?

The carbon footprint is the annual amount of greenhouse gas emissions, mainly carbon dioxide, that result from the activities of an individual or a group of people, especially their use of energy and transport and consumption of goods and services. It's measured as the mass, in kilograms or tonnes per year, either of carbon dioxide (CO2) emissions alone, or of the carbon dioxide equivalent (CO2e) effect of other greenhouse gas emissions.

4.1 Parental behaviour

A moment's reflection will convince you that parental behaviour differs from one family to another. The effect that different parental styles have on the development of the recipient offspring is very difficult to establish. In part this is to do with the host of other differences between families, not least their genetics and socio-economic status. But also the difficulty arises because to determine cause and effect requires prolonged and intrusive observations of a sort that is not possible

The Fungi Classification
A fungus is a member of the kingdom Fungi . The fungi are heterotrophic organisms possessing a chitinous cell wall. The majority of species grow as multi-cellular filaments called hyphae forming a mycelium; some fungal species also grow as single cells. This interactive web page gives you pictures of specific examples of the fungi classification, along with written details for most.

7.4 Summary of Section 7

Fibres of the cochlear nerve synapse on the cells of the cochlear nuclear complex which is the first station of the central auditory pathway. From here signals are sent to the superior olivary complex, the inferior colliculus, lateral lemniscus, medial geniculate nucleus and finally the auditory cortex. The central role of the auditory cortex is the processing of complex sounds.

Each cochlear nuclear complex receives input from only one ear. In the cochlear nuclear complex are several d
