  1. Door to Antiquity

    The Phimai temple complex in Thailand was an important Khmer economic, religious, and military center about 1,000 years ago. Richard M. Levy of the University of Calgary has created an elaborate computer reconstruction of this historic site, allowing visitors to wander the complex without traveling all the way to Thailand.

    See whether BatCam catches a tropical bat visiting a banana, or review QuetzelCam highlights for a murky but impressive view of how such a long-tailed bird jams its plumage into a nestbox. Or, if the cameras aren’t picking up anything in particular, visitors can listen to short recorded commentaries from such denizens as prong-billed barbets […]

    When Galaxies Collide

    Dramatic images from the largest computer simulation ever of a plausible collision between the Milky Way and Andromeda galaxies highlight this report from the National Partnership for Advanced Computational Infrastructure and the San Diego Supercomputer Center. Astrophysicist John Dubinski describes the science underlying the computations. Go to: http://www.npaci.edu/online/v4.9/galaxies2.html and http://www.cita.utoronto.ca/~dubinski/tflops/.

    AIR VIBRATIONS IN ORGAN PIPES REVEALED BY PATTERN IN SMOKE Making smoke rings in organ pipes, to show up the little cyclones that whirl in them when obstacles are placed in the openings, is the curious mode of research adopted by a London physicist, Prof. E.N. da C. Andrade of University College. These little cyclones, […]
