Dr Karl Kruszelnicki

Whenever the announcer gives out the phone number for Karl Kruszelnicki's famous Science Talkback show on Triple J, on Thursday mornings - so many calls come in that the ABC switchboard crashes!

Karl's media career began in 1981, when he started presenting 'Great Moments In Science ' on Double J to pay his way through medical school. Since then, his media career has exploded from radio to include TV, books, newspapers, magazines, scripting, professional speaking, and of course, the Net. His science homepage (which has well over 4 million words on it) gets about 700,000 pages downloaded each week (www.abc.net.au/science/k2).
