Plastic People: Recent developments in humanoid robot technology

Karl Iagnemma at Frieze Magazine writes…

The robots are coming. We’ve heard this claim frequently over the past 30 years: that someday soon robots will be ironing our clothes, washing our windows, and serving our morning coffee. In fact, the nearest we’ve come to achieving this vision of domestic automation is embodied by the iRobot Roomba, a puck-shaped robotic vacuum cleaner that does decent work on tile and hardwood, but won’t venture near pile.

As a working roboticist, however, I can attest that the vision of domestic robotics is finally, if incrementally, becoming a reality. Robots will not be serving our coffee any time soon, but they will be entertaining our children and caring for our – hopefully not my – elderly relatives. And the likely form of these robots is decidedly humanoid. But what should a humanoid robot look like? More..

Electrons dance to a quantum beat in the Hubbard model of solid-state physics

Mathematical models and computer simulations usually begin as aids to understanding, introduced when some aspect of natural science proves too knotty for direct analysis. Facing an intractable problem, we strip away all the messy details of the real world and build a toy universe, one simple enough that we can hope to master it. Often, though, even the dumbed-down model defies exact solution or accurate computation. Then the model itself becomes an object of scientific inquiry—a puzzle to be solved.

A good example is the Ising model in solid-state physics, which attempts to explain the nature of magnetism in materials such as iron. (I wrote about the Ising model in an earlier Computing Science column; see “The World in a Spin,” September–October 2000.) The Ising model glosses over all the intricacies of atomic structure, representing a magnet as a simple array of electron “spins” on a plain, gridlike lattice. Even in this abstract form, however, the model presents serious challenges. Only a two-dimensional version has been solved exactly; for the three- dimensional model, getting accurate results requires both algorithmic sophistication and major computer power.

Announcing the winner of the International Award for Excellence

Congratulations to Kris Belden-Adams, the winner of the International Award for Excellence in the area of technology, knowledge and society for their paper Modern Time: Photography and Temporality

Abstract: Within a decade of photography’s unveiling, the passenger train (1830), computer (1833), and trans-Atlantic telegraph (1844) were introduced, followed by the invention of the telephone (1876), automobile (1890s), cinema (1894), radio (1900-1910), airplane (1903), television (1939), internet (1969), the first popular personal computer (1976), and cell phones (1982). This flurry of technological advances has accelerated the pace of life dramatically, forever altering our experiences and conceptions of space and time. As a consequence, time itself has been the subject of insistent theorization, speculation and anxiety.
This paper will explore the fluid relationship of photography to time, and its connection to these technological forces which conditioned patterns of perception. Roland Barthes, for example, wrote that the photograph has a peculiar capacity to represent the past in the present, and thus to imply the passing of time in general. As a consequence, Barthes argued, all photographs speak of the inevitability of our own death in the future. Barthes’s analysis poses a challenge to all commentators on photography – what exactly is photography’s relationship to time, and to reality?

This paper will address that two-part question by analyzing in detail a sample of understudied vernacular photographic practices. Rather than provide a comprehensive, and necessarily incomplete, study of every possible way in which photography can relate to time, this study will instead focus on illustrating time’s sculptural nature.

My study then will examine the motivations for photography’s insistent struggle to reorganize time’s passage, to freeze or slow it, or to give form to time’s fluctuating conditions. I will suggest that this struggle is both symptomatic of modernity, and is a manifestation of the photographic medium’s conditional relationship to reality, a relationship which arguably has been complicated by digitalization. These trends are shaped by the medium’s status as one among many technologies which redefined time-and-space.

If you have read the paper you may wish to add a review.
