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 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.

He made his TV debut in 1985 as the presenter of the first series of Quantum. Since 1986 he has reported science as a regular on the Midday Show, Good Morning Australia (including a full-time stint in 1991-2 as the TV Weatherman and science reporter). He is currently a regular on Channel 7's breakfast program Sunrise. He has recently completed two series on quirky weather topics for the Weather Channel on Foxtel. Karl also popularises science on radio stations across Australia and, on the BBC, for several hours each week.

Karl has written (so far) 23 books, beginning with Great Moments In Science in 1984 and his latest book 'Great Mythconceptions - Cellulite, Camel Humps and Chocolate Zits' which was released in November 2004, went straight to Number 5 on the best seller list for non-fiction books. According to the "New Scientist" Magazine Karl's last five books have all hit the position of best-selling Popular Science book in Australia.

His enthusiasm for science is totally infectious and no one is better able to convey the excitement and wonder of it all than Dr Karl Kruszelnicki.
