The information revolution of the twentieth century was brought about by microelectronics based on a simple and common material, silicon. Although silicon will continue to be of central importance in the next century, carbon, silicon's upstairs neighbor in the periodic table, will also be of great impor tance in future technology. Carbon has more flexible bonding and hence has various unique physical, chemical and biological properties. It has two types of bonding, sp3 and sp2, in diamond and graphite, respectively. The existence of the latter, "7r-electron bonding" , is responsible for carbon's versatile tal ents. Those materials having extended 7r-electron clouds are called '7r-electron ma...
To many academics, composition still represents typewritten texts on 8.5" x 11" pages that follow rote argumentative guidelines. In Toward a Composition Made Whole, Jody Shipka views composition as an act of communication that can be expressed through any number of media and as a path to meaning-making. Her study offers an in-depth examination of multimodality via the processes, values, structures, and semiotic practices people employ every day to compose and communicate their thoughts.

She stretches the boundaries of composition to include a ...
