This is a fit occasion to call attention to the late Mark Weiser (1952-1999), the great popularizer of "ubiquitous computing," who was a key figure at PARC. I think he was also a visionary in the field of e-paper, which continues to slowly evolve but still isn't there yet.

Astronomers Discover the Coolest Known Sub-Stellar Body 60

Posted by Soulskill from the miles-davis's-home-planet dept.
Hugh Pickens writes "Science Daily reports that using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, astronomers have discovered what may be the coolest sub-stellar body ever found outside our own solar system. Too small to be stars and with insufficient mass to maintain hydrogen-burning nuclear fusion reactions in their cores, 'brown dwarfs' have masses smaller than stars but larger than gas giant planets like Jupiter, with an upper limit in between 75 and 80 Jupiter masses. 'This looks like the fourth time in three years that the UKIRT has made a record breaking discovery of the coolest known brown dwarf, with an estimated temperature not far above 200 degrees Celsius,' says Dr. Philip Lucas at the University of Hertfordshire. Due to their low temperature these objects are very faint in visible light, and are detected by their glow at infrared wavelengths. The object known as SDSS1416+13B is in a wide orbit around a somewhat brighter and warmer brown dwarf, SDSS1416+13A, and the pair is located between 15 and 50 light years from the solar system, which is quite close in astronomical terms."

Police Called Over 11-Year-Old's Science Project 687

Posted by samzenpus from the duck-and-cover dept.
garg0yle writes "Police in San Diego were called to investigate an 11-year-old's science project, consisting of 'a motion detector made out of an empty Gatorade bottle and some electronics,' after the vice-principal came to the conclusion that it was a bomb. Charges aren't being laid against the youth, but it's being recommended that he and his family 'get counseling.' Apparently, the student violated school policies — I'm assuming these are policies against having any kind of independent thought?"

The goal of Computer Science is to build something that will last at least until we've finished building it.
