2.4 Obesity and brain reward systems

Very palatable foods, especially those high in fat and carbohydrate may be potent stimuli for neural pathways in the brain. Direct evidence for this idea has been found in recent studies of non-human animals. For example, it is known that many types of both natural (i.e. food, sex) and drug (e.g. cocaine or amphetamine, opiates, nicotine) rewards are able to stimulate activity within a brain pathway that innervates the ventral striatum at the base of the forebrain (Figure 8).

1.2.2 Bringing in the atmosphere: the natural greenhouse effect

As a dam built across a river causes a local deepening of the stream, so our atmosphere, thrown as a barrier across the terrestrial rays, produces a local heightening of the temperature at the Earth's surface.

(Tyndall, 1862, quoted in Weart, 2004)

Thus, writing in 1862, John Tyndall (Figure 6) described the key to our modern understanding of why the Earth's surface is so much warmer than t

Machine de Turing
Dans les années 30, Alan Turing a inventé une machine abstraite et expliquer la notion de « procédure mécanique » : on parle d'algorithme. Cette machine est la plus élémentaire possible destinée à faire agir des mécanismes de calcul, numériques ou symboliques, comme le font notamment les ordinateurs. La machine imaginée par Turing comporte un ruban divisé en cases, dans lesquelles elle peut écrire des symboles. La machine ne peut lire qu'une seule case à la fois, de même elle é
