It can take just one idea to change the world.
For ten years, One Big Idea has showcased UNSW academics, researchers and PhD students and their world-changing epiphanies.
This 3 November, One Big Idea will celebrate its 10th anniversary by inviting program luminaries back to share the profound, the pressing, and the provocative updates to their original talks.
From malingering political leaders to magic mushrooms for mental health. From quantum computing powered by light to AI in warfare. From the threats humanity poses to itself, to saving oceans from the brink of extinction. This evening is sure to cover all corners of humanity.
