Blaise Aguera y Arcas reveals two innovative technologies: Seadragon and Photosynth. Both are about how we and our computers mutually produce, consume and interact with visual information. Both technologies are also suggestive of sweeping changes in our "œvisual ecosystem" over the next several years. The prerequisites for these changes - ”inexpensive CCDs, multiresolution, powerful computer vision algorithms, better bandwidth and processing power, graphics acceleration - ”have been steadily building up for many years. Here we will explore what can happen when these new capabilities converge with the collective effects of Web 2.0.

Physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries. Its legacy is tangible, with terms like algebra, algorithm and alkali all being Arabic in origin and at the very heart of modern science - there would be no modern mathematics or physics without algebra, no computers without algorithms and no chemistry without alkalis. For Baghdad-born Al-Khalili this is also a personal journey and on his travels he uncovers a diverse and outward-looking culture, fascinated by learning and obsessed with science. From the great mathematician Al-Khwarizmi, who did much to establish the mathematical tradition we now know as algebra, to Ibn Sina, a pioneer of early medicine whose Canon of Medicine was still in use as recently as the 19th century, he pieces together a remarkable story of the often-overlooked achievements of the early medieval Islamic scientists.

Vint Cerf: la complessità della rete è determinata dall’eterogeneità dei software presenti nei nodi. E’ necessario elaborare nuove teorie della complessità in grado di generare nuovi algoritmi di calcolo e di prevederne il percorso in un ambiente di network. “Verranno sviluppati nuovi protocolli, in modo che i computer possano negoziare come i calcoli dovranno essere eseguiti”. Vint Cerf: the net's complexity is detrmined by software's heterogeneity present in knots. It's necessary to elaborate new theories of complexity able to produce new algorithms of calculus and to foresee the way to a netwok's environment. "New protocols will be developed in order to let computers negotiate how calculus will be realized".
