  1. Why Did Europe Conquer the World?

    Hoffman, Philip T.
    Between 1492 and 1914, Europeans conquered 84 percent of the globe. But why did Europe rise to the top, when for centuries the Chinese, Japanese, Ottomans, and South Asians were far more advanced? Why didn’t these powers establish global dominance? In Why Did Europe Conquer the World?, distinguished economic historian Philip Hoffman demonstrates that conventional explanations—such as geography, epidemic disease, and the Industrial Revolution—fail to provide answers. Arguing instead for the pivotal role of economic and political history, Hoffman shows that if variables had been at all different, Europe would not have achieved critical military innovations, and another power could...

  3. Conversationalist Robot in student cafeteria

    Trautman, Peter
    N.b.:In the wide upper panel, the position and trajectory marker (red lines and dots) are accurate according to the underlying grid. However, the projection of the video is offset slightly (due to camera curvature) from the tracks. This is an error in presentation; tracking error was almost uniformly within 1 foot of truth. A highly useful behavior of the robot was that it was always in motion. This was achieved safely by doing the following: if a collision was imminent, the forward velocity was set to zero. However, the rotational velocity was not set to zero. The navigation algorithm continued generating...

  4. Dance with a robot

    Trautman, Peter
    N.b.:In the wide upper panel, the position and trajectory marker (red lines and dots) are accurate according to the underlying grid. However, the projection of the video is offset slightly (due to camera curvature) from the tracks. This is an error in presentation; tracking error was almost uniformly within 1 foot of truth. Sometimes, our navigation algorithm resulted in quite humorous situations: at the beginning of one run, while the navigation algorithm was still starting up, a patron came up and began inspecting the robot. The robot, sensing an imminent collision, set its velocity to zero, and began searching for a...

  5. Dense crowds and a careful ending

    Trautman, Peter
    The continual motion behavior of the robot can be quite useful in dense crowds. For instance, the reactive robot did not display this behavior---when a collision was imminent, it stopped completely. Unfortunately, a completely stopped robot is very hard for a human to understand. Is this robot turned off? Is this robot waiting for me? Meanwhile, the multiple goal interacting Gaussian process robot displayed intentionality. Animators call this behavior "readability'', and it can be employed to create a more human like intelligence N.b.: In the wide upper panel, the position and trajectory marker (red lines and dots) are accurate according to...
