Dr Karl is best known here in Australia for his ability to make science not only accessible, but engaging and fascinating, He’s been a staple in our media landscape from his early days on Triple J, to his multiple podcasts, books, and extensive media presence - a true science story-teller. With the launch of his memoir ‘A Periodic Tale’ we explore in this conversation his early years as the only child of Holocaust survives who fled to Australia in 1950. He then described undertaking a convoluted cacophony of a career. From working as a physicist in a steelworks, to racing modified rally cars, his drug-crazed hippie years in Papau New Guinea, to training as a medical Dr off the back of an off-handed comment that Dr Fred Hollows said to him once. After he applied to be a NASA astronaut in the 1980s and 'failed', he ended up live broadcasting the first space shuttle launch on Triple J instead. Unexpectedly, that blasted off his media career, and from there it was a stratospheric rise from radio to TV, books, newspapers, speaking, podcasts and the internet. You will hear from this conversation a little about how Dr Karl’s brain works - he has an insatiable curiosity that continues to drive pure wonder and awe. Actually he teaches us all that you don’t have to know the answers, as long as you continue to ask questions. This conversation is one worth holding onto, and allowing it to ignite your own curiosity. And I can thoroughly recommend Dr Karl’s memoir ‘A Periodic Tale’ to absorb more of his wisdom and experiences.
