Fri, 07 May 2010 05:30:11 -0800Braille is facing extinction, says Canadian newsweekly Maclean's, thanks to strained budgets, audiobooks and text-to-speech. "In the 1950s about half of all blind children learned Braille, says the U.S. National Federation of the Blind. Today, that number has fallen to 10 per cent -- and it's about the same in Canada. For some, like NFB director Mark Riccobono, that means we're letting blind children grow up as illiterate as Braille's 19th-century contemporaries. 'If only 10 per cent of sighted children were being taught [to read],' he told Maclean's, 'that would be considered a crisis.'"

Porter (1871-1949) designed and produced a remarkable, bronze-cast garden telescope in the 1920s. Fewer than 60 of these unusual Newtonian reflectors were ever made, and they're even harder to find now: earlier this year, one went for $18,000 at auction. But a reproduction of the Porter Garden Telescope is now available, for a mere $59,000 (it's cast bronze on a marble pedestal); a local cable station has a profile of the people behind it. Via Sky and Telescope.
