2.1 Political responses to climate change and the environment

Not for the first time in this course, you are faced with a term that is important but difficult to define precisely.

In this section, the range of political responses to climate change and environment–economy inter

1. Why Teach Art?

Acquisition of sight precedes language. In a tangible sense visual engagement with the world situates us and defines who we are.

Émission d'ondes par un obstacle oscillant et mobile (Ondes et instabilités)
Ce cours étudie le train d'ondes émis par un obstacle oscillant et mobile dans un milieu fluide dispersif ou non dispersif. On s'intéresse au sillage lointain ou a des obstacles de petite taille. On montre que seules les ondes oscillant a la même pulsation que l'obstacle sont émises et que le sillage se disperse en paquets d'ondes voyageant avec leur propre vitesse de groupe.

2.2 Photographs as primary sources

As a primary source of historical evidence the still photograph remains largely unexamined and unexplored. Many academic historians remain wedded to the written word and are often mistrustful or dismissive of the still image. Photographs continue to be used merely to prettify or to provide necessary breathing space in dense texts. In fact, the task of finding ‘illustrations’ is often only considered after a book is written. What could indicate more clearly that the photograph has n
