...energy, such as moving matter around within a solid without risking melting or changing the basic shape of a component. On the other hand, it can be a real nuisance. It can make magnetic disks 'forget'. It can leave materials 'sapped' of their strength. Just a few degrees of temperature change can make some things unrecognisably different. Temperature really does present...

...the tiny green structures called chloroplasts. These give leaves their colour, and capture light energy from the Sun. What happens next is a complex chain of reactions that can be summarised very simply. Water and carbon dioxide are converted, using the sun's energy, into simple sugars. The oxygen released in the reaction is now available for other organisms to respire....

Fortunately, there is a...
