The Sydney Science Festival is back in 2019. The festival kicked off yesterday on August 6 and runs until the 18th, with hundreds of events, talks, workshops and exhibitions covering all areas of science, technology, climate change and maths. The festival brings together international figures like Sylvia Earle and Claire L. Evans with local heroes like Dr. Karl and Eddie Woo to promote, discover and debate every aspect of science. Speaking to us about this event was Catherine Polcz, the producer of the Sydney Science Festival.
