Language and thought: introducing representation

...chemistry and physics have been increasingly integrated with one another. The structure of the Gricean Programme is reflected in Figure 2, which I discuss below, starting at the top and following the arrows in order. The diagram looks complex, but most of it is already familiar. We have seen already that Grice makes a plausible case for the existence of an ambiguity in...

Wildfires: environmental and social entanglements

...chemistry of fire is a biochemistry. And as soon as plants began colonising land, they burned, and they’ve been burning ever since. But they burned in a way that was very patchy. Some places, some eras, had lots of fire routinely. Others only episodically or even rarely. And one reason is that life did not control the third element of the fire triangle, namely ignition....

...chemistry recently, the concepts may be relatively familiar and you may be able to read through this box quickly, or skip it completely. Box 2 Introducing chemical equations When chemists want to describe a chemical reaction in which one set of substances (the reactants) are transformed into another (the products), they usually do so by means of a chemical equation. The...

The science of nuclear energy

...chemistry, and chemistry is all about the interactions of the electrons of the atom, not the nuclei. The number of electrons in a neutral atom is always the same as the number of protons in its nucleus. You may be wondering what role neutrons play and you’ll find that out in the next section...Week 1: Into the atom: 1.1.1 Isotopes - So, the properties of a given element...

...chemistry to Volkswagen for this elegant method of ‘solving the problem of excessive automobile pollution emissions’. The effect on the ‘green credentials’ of diesel cars has been considerable with calls for them to be banned from many European cities. The scandal has seriously assisted the move from fossil fuelled to electric cars. Activity 3 Timing: 15 minutes A...

...chemistry of this wonder drug but it was a derivative of picric acid and quite harmless when well diluted and used as a bitter tonic. (Porter, 1999, p. 196) Such medicines seem little different to patent medicines, which doctors so frequently condemned.
