In March 2021, Afghanistan's Taliban rulers banned female students over the age of 12 from singing in public. The prohibition sparked a wave of online protests across the country, with women and girls posting videos of themselves singing, using the hashtag "I am my song". Aged just 14, Nila Ibrahimi's song, Boro Bakhair Ba Maktab or "Go to school" became an anthem of the movement.

The 2025 Gandhi Oration was recorded at University of NSW Centre for Ideas on 2 October 2025.

The Panopticon was a prison design by the famous philosopher and social reformer Jeremy Bentham which placed prison guards in a central tower overlooking inmates. So why does scientist and climate advocate Tim Flannery want us to re-imagine the Panopticon as a path towards a more compassionate society? And why does he find warmth and connection even in conflicted communities angry about climate change policies?

This event was hosted by RMIT University and Now or Never, Melbourne's festival of art, ideas, sound, technology.

Universities are under pressure — particularly the study of subjects like languages, history, social sciences and the creative arts. This lecture looks back to a time, post war, when governments turned to universities to transform Australia's economy and society, and backed it up with significant investment and oversight. In the face of contemporary challenges, is it time once again to rethink the purpose of universities — and particularly the study of the humanities — to equip Australia with the skills it needs to survive and thrive in the 21st century?

Stephen Garton's Australian Academy of the Humanities Annual Lecture "When Universities Mattered" was recorded on 12 November 2025.

An edited version of this lecture is published in the March issue of the Australian Book Review.

As Bridgerton continues to captivate millions and we just marked the 250th anniversary of Jane Austen's birth, the Regency era has never been more thrilling. But how much must you know about corsets and carriages before you can break the rules? What's behind Bridgerton's runaway success? Should we love or loathe what it does with Regency history? Indeed, what would Jane Austen think of it all?

Harvard psychologist and bestselling author Steven Pinker is a fierce advocate for intellectual and academic freedom — and one of the world’s most prominent and provocative thinkers about human language, the mind, and how societies work. He joins Big Ideas host Natasha Mitchell with an 800-strong Melbourne audience to discuss his latest book When Everyone Knows That Everyone Knows: Common Knowledge and the Science of Harmony, Hypocrisy and Outrage. Steven Pinker doesn’t shy away from controversy — amidst the Trump administration's attacks on his own university he recently penned a NYT piece titled Harvard Derangement Syndrome — challenging the cancellation, character assassination and censorship of scholars who investigate controversial ideas.
