What do crocodile jaws, chocolate, artificial intelligence and a flower-eating hippie have in common?
They all found their way into a lively evening with Dr Karl Kruszelnicki in Cooktown.
Around 250 people gathered at Cooktown Events Centre on Friday 30 October for a night of big ideas, surprising stories and live music, with plenty of opportunities to put their own questions to one of Australia’s best-known science communicators.
And the questions started well before the evening crowd arrived.
Earlier in the day, Dr Karl met 110 students from Cooktown State School and Endeavour Christian College to talk about science, artificial intelligence, computers and what the future might hold. Among the possibilities was one particularly memorable thought: could someone sitting in that room become the first person to achieve immortality? Quite a conversation to take home from school.
The Stronger Together Community Choir opened the evening, bringing local voices together before Dr Karl took the audience on a journey through his remarkable life.
From arriving in Australia as a young refugee, he went on to work as a physicist, mechanic, taxi driver, filmmaker, biomedical engineer, children’s doctor and television weatherman. His adventures have included making music films in Papua New Guinea, building equipment for eye surgeon Fred Hollows and broadcasting from Antarctica, where a blizzard extended his stay. His personal transformation was just as colourful, from bearded hipster and flower-eating hippie to the bold-shirted science communicator Australians know today.
With a life story like that, there was always going to be plenty to talk about.
Everyday experiences became invitations to look a little closer. Why can mixing spirits with diet soft drink make people drunker? What makes coffee and chocolate such a heavenly combination? And why are we sometimes most confident about the things we know least about?
That last question took the audience up the “mountain of stupidity” as Dr Karl explored the Dunning–Kruger effect, illustrating how a little knowledge can come with a remarkable amount of confidence. It was an entertaining invitation to recognise the limits of our own understanding and keep asking questions.
He also explored the difference between correlation and causation: just because two things happen together doesn’t mean one caused the other. Looking beyond an apparent connection and asking what the evidence actually shows was a recurring theme throughout the evening.
That commitment to evidence extended beyond our planet. As much as Dr Karl would love to discover another life form in the universe, he explained that we do not yet have confirmed evidence of life beyond Earth. It was a reminder that even the most exciting possibility needs evidence, however much we might want it to be true.
Climate change brought another moment for reflection, as Dr Karl discussed opportunities missed in the 1990s and the influence of greed on decisions with consequences for our shared future.
When it was the audience’s turn, the questions had a distinctly Far North Queensland flavour. How can a person hold a crocodile’s powerful jaws shut once they are closed? And why does the wet season sometimes seem reluctant to leave?
Other questions explored saunas, ice baths and biological ageing, prompting a broader conversation about the benefits of making time to care for ourselves and our mental wellbeing.
Cairns jazz group The North Project Trio provided a relaxed musical finish to the evening. Meanwhile, in the lobby, Dr Karl continued answering questions from community members, keeping the conversation going well beyond the keynote.
From the school visit to those final conversations, it was a day that gave Cooktown plenty to think about, plenty to smile about and perhaps a few new questions to ask over coffee and chocolate.
An Evening with Dr Karl was presented with assistance provided by the Australian and Queensland governments through the jointly funded Disaster Recovery Funding Arrangements.
