Big Ideas

Has the way politicians speak ever made you shout at the television, feel bamboozled, helpless,  or shut out of democratic debate over our shared future? Pollie-talk can make important issues opaque, the inequitable seem fair, and the fair seem inequitable. Join Big Ideas host Natasha Mitchell for some straight talk that cuts through the spin and jargon with Richard Denniss (author of Econobabble: How to decode political spin and economic nonsense), Yanis Varoufakis (author of Technofeudalism: What Killed Capitalism),  Joelle Gergis (author of Humanity's Moment: A Climate Scientist's Case for Hope) and Thomas Keneally (Schindler's List).

Only 50 years ago, if you were 60 years old your chance of dying was the same as an 80-year-old's today. Thanks to progress in medical technology, you can live longer than ever before. Quantum technology and quantum screening, modelling with digital twins, harvesting the power of AI and real time monitoring of your molecules – a panel of health experts discusses the new frontiers in the development of drugs and health technology.

Gender equality isn't just about equal pay, it's a health and safety issue. Women perceive safety very differently to men, and that's why they need a seat at the table when policies are being nutted out. Just a month after Australia gets its first Gender Equality Strategy, Stephanie Copus Campbell speaks about her first-hand experience on women's rights and discrimination in Papua New Guinea and many other countries in the region — and her observations as the international Ambassador for Gender Equality. Her verdict: we are going backwards worldwide.

How valuable are trees as an alternative crop? And what's the role of agroforestry in the future of sustainable farming?

They use of shark nets to protect us from sharks is highly controversial. Do they work, what do they do to marine life, are there alternatives, and why are sharks so political?  Join Natasha Mitchell and guests at the 2024 Ocean Lovers Festival for a robust interrogation of of an issue that ignites passions.

It's a question that has focused the minds of astronauts, scientists, space entrepreneurs and enthusiasts alike – is there, could there be, life on Mars? The race is on to find out, with NASA hoping to land astronauts there by the late 2030s.

Folk legend Eric Bogle is opening up and talks about his life, his thoughts about death, friendship and love and why having a deeper message for writing songs is so much more important than money and fame. It's a rare opportunity to share a conversation with one of the best and most prolific songwriters of the last several decades. His songs have become Australian classics – like The Band Played Waltzing Matilda or No Man's Land. And as a very special treat – you'll hear the world premiere of his latest song … finished on the way to this event.

What is the future of Israelis and Palestinians in the Gaza strip and surrounding region? Can the past help us understand the tumultuous, horrifying present? And is a two-state solution a realistic response to the war in Gaza or not? Walkley Award-winning Australian journalist John Lyons, Israeli historian and political scientist Ilan Pappé, American essayist and author Nathan Thrall, and American political advisor Bruce Wolpe share their perspectives.

A wooden sarcophogas is sold in a Cairo market in the late 1800s, transported to Australia, and held in a University of Sydney collection. It remains closed for over a century. And then scientists opened its lid.  What happened next? Two leading Australian Egyptologists join Natasha Mitchell to consider the ethics, history, and science of a quest to understand life and death in Ancient Egypt and get a glimpse into one woman's world over 2500 years ago. But is it really Mer-Neith-It_Es?

For decades, Mary Beard has forged her own path through the male dominated field of academia, from the ruins of Rome to the trenches of Twitter, to become "the world's most famous classicist".

The best of talks, forums, debates, and festivals held in Australia and around the world.

What is the best response to hostage diplomacy? Pay the ransom? Sanction the responsible country, or individuals? Go public, or pursue quiet diplomacy? Can countries preserve bilateral relations, while at the same time advocating for the rights of their unlawfully detained citizens?

Water is life. Rivers give life. But water and the rivers it flows down are also heavily politicised, and at the heart of battles over who gets access to water, what's killing our rivers, and what happens when they kill us during catastrophic floods. Join Natasha Mitchell and guests at this Adelaide Writers Week event with Senator Sarah Hanson-Young, Barrister and author Richard Beasley, grazier and activist Kate McBride, and environmental historian Dr Margaret Cook.

Australia’s bushfires are more intense, more frequent, and more costly. So how can we prepare for the inevitable – what proactive steps can communities take to protect themselves, and do we have the settings right?

Many of you are involved in a charity: Handing out meals to homeless people, caring for surrendered animals in a shelter, organising soccer games to keep the youth in the neighbourhood on the straight and narrow. But are you sure that your charity is putting the time and also the money that you give up to good use? What makes a charity successful? And how can you future-prove them?

Grace is a hard word to define, but in her latest book, author, journalist and broadcaster Julia Baird explores the concept, and how finding and nurturing it in each other – and ourselves - can help us through dark times.

When governments say they can't afford to fix climate change or lift kids out of poverty are they speaking the truth? American economist Stephanie Kelton challenges economic orthodoxy in her book The Deficit Myth: Modern Monetary Theory and the Birth of the People's Economy. She joins Natasha Mitchell in conversation at this 2024 National Sustainability Festival event.

Bessel van der Kolk, one of the world's foremost experts on trauma, discusses his pioneering research into traumatic stress and its impact on our brains and bodies. Traumatised people experience incomprehensible anxiety, numbing and intolerable rage. Trauma affects their capacity to concentrate, to remember, to form trusting relationships, and even to feel at home in their own bodies. And he explains promising treatments, including neurofeedback, psychedelic therapy, psychodrama … and dance.

Different generations agree that youth mental health is in decline, but disagree about the causes. We explore generational attitudes to the economic and social drivers of mental ill-health in young people.

Liberalism isn't just a political philosophy but the basis of a truly meaningful life. That's the bold statement of philosopher Alexandre Lefebvre, author of the forthcoming book Liberalism As A Way of Life. Should individuals be free to pursue their own passions and interests in life? Does liberalism mean more than freedom of speech and small government? You might not identify as a liberal, but are we in fact all liberals at heart?

Quantum computing is all about physics, but for those looking to pioneer and revolutionise science, there are certain human qualities needed as well. That is the topic of these final two Boyer Lectures with a global leader in the field of quantum computing, Professor Michelle Simmons.

Imagine a machine with more power than all the computers in the world combined. This is the promise of quantum computing. In these 2023 Boyer Lectures, Professor Michelle Simmons explains why building a machine that operates at the scale of atoms has the potential to revolutionise society, and why Australia is at the forefront of the global race to develop the first one.

The US has claimed that it has “no greater ally than Australia”, but with the stability of its democracy in question, what are the risks, and the rewards, of waltzing in step with the world’s greatest superpower?

Hear from four “many worlds travellers” who have visited parallel worlds to explore themes of Indigenous rights, disability, gender and the climate crisis, to show us that a different way is within reach.

Can you put a price tag on regional education? In fact, you can. The large difference in the quality of education between people who live in rural and regional Australia compared to those who live in the cities is costing our economy over 55 billion dollars…. AND we also talk about the role of advocates in conflict situations, in particular lawyers, speaking truth to power and speaking up for the weak.

From dark energy to the nature of time, some of the most baffling mysteries in cosmology point to a surprisingly complex answer: The idea that alternate layers of reality might exist beyond the reach of our current physics, and perhaps even outside the Universe itself. Philosophy can help navigate the many enigmas of physics. In fact, there is a long history of the entanglement of the two.

Two years since Vladimir Putin’s Russia invaded neighbouring Ukraine, the risks are as grave as ever, including the possibility of war spilling into Europe, and the nuclear threat. What next for the Ukraine war?

We hear from the nation's anti-corruption leaders, including NACC Deputy Commissioner Nicole Rose, about the state of corruption in Australia.

Pioneering electronic musician and performer Laurie Anderson invites you contemplate the wonders of time. Time is one of the most impermanent forms of measurement that humans have invented to help manage our lives. We couldn't function without it. Do you feel like you're running out of time? Which way is time going? Are you able to stop time? What is the role of time  in ethics, or how you experience trauma? Laurie shares a creative conversation with twice-Booker-shortlisted author Tom McCarthy as they look to arts and literature for answers.

Best-selling author Holly Ringland says that everyone can be creative – yes, even you! Be it painting, cooking, knitting a jumper or writing a song. It's often self-doubt and the fear of criticism and judgement that's holding you back. The voice in your head telling you that you're not good enough. It doesn't have to be like this.

Most of us know that exposure to nature is good for us, because we’ve experienced it ourselves. Doctors can even prescribe time in nature to patients, for the health benefits. But increasingly, we’re understanding – and measuring - just how nature helps us – our minds, bodies, and society.  This event is brought to you by the Australian Land Conservation Alliance as part of the National Private Land Conservation Conference held in Canberra on October 17, 2023.

Celebrities, and their fans, wield tremendous economic, cultural and political influence – and none more so than US pop superstar Taylor Swift. Academia is getting on board, with university courses now entirely dedicated to studying the icon. But celebrities and their fans have not always been taken seriously, by academia, or broader society – particularly when it’s someone idolised by young girls.    Well, these academics are trying to change that. Ahead of Swift's record-breaking Australian tour, 160 scholars from around the world came together in Melbourne for the inaugural Swiftposium conference, to engage in critical dialogue about Swift’s popularity and its profound influence on society, from feminism, to gender, fandom, popular culture, literature, the economy, the music industry, and more. This event was presented by the University of Melbourne from February 11 to 13, 2024.  “The worst kind of person is someone who makes someone feel bad, dumb or stupid for being excited about something.” - Taylor Swift, 2019

Have you ever followed your intuition, or been guided by a gut feeling? Is intuition real or imagined? Can it be learnt and harnessed for good in our lives? Neuroscientist and psychologist Joel Pearson wanted to find out. He joins Natasha Mitchell to discuss his book The Intuition Toolkit – the New Science of Knowing What without Knowing Why.

What has happened to civil debate and the reasonable exchange of competing ideas in public, to conversations that might lead to productive compromise, or simply agreeing to disagree?  Has civil society always been so... uncivil?

There's nothing like an innocent story to rupture reality! Fiction is a literary seismograph for social conflict and stories can change minds. They have helped end slavery, and end discrimination. Hear the powerful story of how. Also, a gaming scholar with a blitz through the history of queer games. The creative games industry is pretty gay — so why isn't there more queer representation in gaming stories, and does the recent growth in queer games benefit all players? Enter a world of gaming, fan culture, gay romance, the essence of trans-ness  to hear how the answer may not be binary.

Public libraries are for everyone, but last year, the LGBTIQA+ community became a target for exclusion by anti-queer campaigners, when drag story time events – designed to celebrate diversity and embrace rainbow families –were shut down or postponed due to threats, protests and abuse. Librarians, drag artists, families and council staff were on the frontline of these attacks. To counter the hurt caused by these campaigns, the LGBTIQA+ and library communities joined forces to celebrate and reclaim libraries as safe spaces for everyone.

Some things feel impossible to change without money and power. Meet four trailblazers didn't let that stop them. Fighting corporations. Stopping violence. Transforming talk on sex and consent. Helping men heal from childhood trauma. They join Natasha Mitchell and an audience of high school students to explore what pushed them to act.

Women and girls in Iran continue to take to the streets and protest gender oppression and human rights abuses. And too often they risk their lives for this fight. Iranian-born human rights advocate Nazanin Boniadi has used her public profile as an actress to campaign in solidarity with the people of Iran. For that, she's been honoured with the 2023 Sydney Peace Prize. The 'Women, Life, Freedom' movement has demonstrated the unifying power and potential of women's rights as a lever for mobilisation and demands for change. The movement makes the pursuit of women's rights an essential part of any pathway towards fundamental change in Iran.

US singer, songwriter and producer Caroline Polachek is known as one of the most inventive pop musicians working in the industry today, pushing the boundaries of what the genre is, and what it means for the people who listen to it. Off the back of her acclaimed seventh album, ‘Desire, I want to turn into you’, Polachek opens up about her creative process, her varied career, and why pop should be respected as an artform in its own right.

Speaking freely isn't only about Freedom of Speech legislation, it's equally about social norms, loving your family and courage. Authors Lea Ypi and Hayley Campbell discuss what's difficult to talk about. Death and what happens your body when you die. And whether Albania has experienced more freedom in communist times – only in very specific circumstances. They explore the factors that allow us to speak freely, what forces can constrain these … and what happens when we are unleashed to speak the truth.

Housing is a hot mess in many remote Aboriginal communities,  including Tennant Creek, and the rollercoaster of government policies and interventions hasn't helped the situation. What's on offer is often culturally unsafe, crowded, and a climate disaster. But housing is hard to fix too. This group of Traditional Owners, health professionals, architects and others have a vision for how.

Psychedelics were once the domain of hippies and cults, but these drugs have come long way from the ‘turn on, tune in, drop out’ countercultural philosophy of the 1960s and 70s. Nowadays, the field of psychedelic research is experiencing a resurgence, with substances like psilocybin, MDMA and ketamine being used in controlled laboratories to treat complex mental health issues. In 2023, Australia became the first country in the world to permit psychiatrists to use psychedelic medicines to treat certain patients. But are psychedelic assisted therapies a silver bullet cure for mental health disorders, or have the regulations gotten ahead of the evidence?

Finishing your undergraduate assignments in English Literature in breaks between selling drugs … fighting and hurting people and committing crimes while discussing the finer nuances of human morality. Best-selling author Gabriel Krauze speaks openly about his life as a former gang criminal living on a notorious housing estate in South Kilburn in London - with quite different extra-curricular activities than most other English literature students. Because that's his other side: A passionate student with a love for art and philosophy.

Tiger parents: do their methods raise happy and successful human beings, or burnt out, damaged therapy cases? In this hyper competitive age we live in, could their approach bring up a new generation of winners this country needs to get ahead? Six Asian Australian comedians, writers and performers thrash it out in debate form to decide: Does Australia need more tiger parents? The audience’s applause will decide the winner.

From the moment we’re born, we all age. So why limit the possibilities? The latest Intergenerational Report describes Australia's ageing population as an economical and fiscal challenge ... a burden. Ageism is rife, but to age is to live. So what about thriving too? Find out how there's magic to found when relationships across the generations are fostered and why we all benefit — whether we're young, middling, or older

Craig Foster has a vision for the future: An Australia without racism, with equal access to food and representation and compassion for refugees. But it's 75 years since the 75th anniversary of the Universal Declaration of Human Rights, and Craig Foster has a warning for us: Things need to change, and hopefully it doesn't take another 75 years. His passionate insights will leave you with a lot to think about …. heavy and uncomfortable thoughts.

In her fifth Massey lecture, Escaping the Burrow, self-described "feral intellectual" Astra Taylor explores how insecurity can also offer us a path to wisdom — individually and collectively. A vision of hope and possibility. For the CBC Massey lectures, the renowned filmmaker, writer, political activist, and sometime rock musician Astra explores how our society now runs on 'manufactured' insecurity — and asks, is there another way?

An appeal for solidarity with species other than our own, in this fourth Massey lecture by renowned Canadian-American filmmaker, writer, political organiser, rock musician and self-described 'feral intellectual' Astra Taylor. We, Them, Us, our stories and actions are all intimately intertwined across space, place, and time. In her thought-provoking CBC Massey lectures, Astra explores how our society now runs on heightened sense of manufactured insecurity. Can that be unmade?

In her third provocative CBC Massey lecture, Canadian-American filmmaker, writer, political organiser, rock musician  and self-described "feral intellectual" Astra Taylor argues our innate existential insecurity is vital to our curiosity,  creativity, compassion, and capacity to care. Drawing on her own childhood, she asks, how can educators better foster these? We're in the middle of an attack on our essential nature, Astra argues, with confronting consequences for our society and state of mind. In this 5 part CBC Massey lecture series, Astra explores how our society now runs on a sense of manufactured insecurity — and what needs to change.

We take certain fundamental rights for granted, but who got to define them and are they enough? You'll find solidarity in these stories of baroners and commoners from filmmaker, writer, political organiser, sometime rock musician  and self-described 'feral intellectual' Astra Taylor. In this year's thought-provoking CBC Massey lectures, Astra explores how our society runs on 'manufactured insecurity' — and how we can challenge that.

Who was Cura and what's she got to do with how capitalism shapes our lives and psyches? In this year's thought-provoking CBC Massey lectures, renowned Canadian-American filmmaker, writer, political organiser, rock musician  and self-described 'feral intellectual' Astra Taylor explores how our society is now driven by a 'manufactured insecurity'. Fundamental to the human condition is a sense of existential insecurity — the sense that we are all vulnerable and dependent on each other. But manufactured security came later, and Astra Taylor argues it needs an urgent rethink, for the sake of us all.

Three successful authors Akuch Anyieth, Shannon Burns and Catherine Deveny talk about memoir, and why they're interested in the form. Moderator of the discussion Yves Rees asks the panel to reflect on whether the personal storytelling genre is popular because of voyeurism, a desire for intimacy between writer and reader or just a hunger for trauma porn?

Two teams of heavy-hitters debate the fate of human creativity in a world of artificial intelligence. In a Big Ideas first, two A.I debaters are taking to the stage, and with strong opinions! Are the bots coming for Boticelli and the Bronte Sisters? Will humans be thrown in the dustbin of civilisation as our artistic expression is usurped by silicon? Or, will the bots help you unleash your creative potential like never before?

In early 2020, as Australians were being locked down, something strange was happening in an inner-suburban hotel in Brisbane. A group of men, previously invisible to most Australians, gathered on the hotel balcony wielding hand-made banners. Who were they? And how did this moment change the minds of middle Australia? It's 10 years since Kevin Rudd declared "no one who arrives by boat will ever settle here". The fallout catapulted thousands of lives into a decade-long limbo. Two of the men on that Brisbane balcony join host Natasha Mitchell and other guests at the Brisbane Powerhouse as part of the Portraits of Protest exhibition.

It's possibly the greatest ever example of artistic censorship in Australian history. Police have requested hip hop to be taken off online streaming platforms, stopped bands from performing in Australia, and amended visa regulations so local hip hop artists can't perform overseas. Their claim is that hip hop is inciting violent and criminal behaviour. But it's an old debate that first emerged in the birthplace of hip hop more than two decades ago. Osman Faruqi shines a light on parallels to the hip hop wars of 1990s America, the role of police bias and profiling, and concerns for free speech more broadly.

What do the streets feel like where you live? Unsafe for kids to ride to school, big busy highways, limited public transport, cars reign supreme? From electric vehicles to bike-friendly buses — be inspired by these globally renowned movers and shakers. They're using the regional town of Bendigo and international case studies to re-imagine how we can live and move. Transport accounts for a staggering quarter of global greenhouse emissions. Could one Australian town lead the way and hit zero transport emissions by 2030?

Three influential women explore the power, the politics, and the cost of speaking out.

Are Greek-Australian's now considered to be 'white' in Australia's colourful social fabric? A panel of prominent Greek-Australians discusses questions of identity and belonging. As they have evolved into one of the oldest migrant groups in the country, is the era of Greek 'otherness' over? And what role did anglicising surnames play in our journey towards acceptance?

"Are they a girl or a boy?" That question is often asked about a newborn. But what if you're born with genetic variations in sexual development, also known as intersex conditions, and possess both typical male and female physical traits? New legislation tabled in the ACT is set to limit the scope of medical treatments and surgeries for such children. Intersex activists have campaigned hard for the law saying the human rights of the child to bodily autonomy is paramount. But some argue not all lived-experience voices are being heard, and are concerned the new laws could criminalise clinicians, carers and parents.

The best of talks, forums, debates, and festivals held in Australia and around the world.

Meet some climate refugees of a different kind. From the Western swamp tortoise to honey ants to whales, can they just up-stumps and move house if things get too hot under the collar? From understanding First Nations science to breaking up the siloed western conservation practices, are there better ways to make life possible for every being on a warming planet?

Questioning whether travel is ethical is probably the last thing on your mind when you decide to go on holiday. But for increasing number of travellers, 'ethical travel' is the preferred mode for tourists who don't want their holiday to just be an extractive exercise. So what are the ethical obligations for those who have the privilege to travel? And what does ethical travel mean in practice… ?

Would you eat protein brewed in a vat from bacteria instead of meat? "Nom nom nom!", you might say. George Monbiot probably agrees. One of the most influential thinkers on the future of of the planet, now he's interrogating what's on our dinner plate, and the staggering business of how it got there. He joins Natasha Mitchell to discuss his provocative book, Regenesis: how to feed the world without devouring the planet. And it all comes down to connecting with the Tolkienesque world beneath your feet.

The planet's hotter than it has ever been. July was the Earth's hottest month ever recorded since records began. And the consequences of this warming is increasingly becoming too hard to bear — particularly among those who don't have access to climate control. So what happens to our bodies in times of heat extremes? And what will happen when these extremes become the new 'normal'? It's something the veteran environmental reporter Jeff Goodell explores in his new book Heat: Life and Death on a Scorched Planet.

If you can't control it – then don't worry about it. It's one of the core messages of stoicism. Much easier said than done. But if you manage it, it can make your life a lot happier and calmer. That's not to say you should sit back and ignore injustice. The stoics have an answer for that as well. On Big Ideas, you'll hear about the ancient philosophy of stoicism and how to apply its principles to modern life. War, climate change, pandemic and endless social media platforms onto with you can project and amplify your anxieties. It seems like we all can use a good helping of stoicism.

For more than 100 years, birdwatchers have searched for evidence that one of Australia's rarest native birds is not extinct. And they might be a step closer to solving the mystery of the Buff-breasted Button Quail. It lives in the humid savannas of Cape York. And we know that this habitat is changing. If we want to have any chance of finding and even saving this bird, we have to act quickly.

We make machines, but do our machines also make us? And who's in control really? Superstar anthropologist, technologist, futurist, cyberneticist, and Silicon Valley insider Genevieve Bell joins Natasha Mitchell with young cybernetic creatives Hannah Feldman, Matt Heffernan, Ben Swift,   to talk machines, minds, messing with the code and what it would take to make technology and the world better.

Movie or TV roles for older women accurately reflecting contemporary, society and experiences are rare. Sigrid Thornton, Rachael Maza, Sophie Hyde and Anousha Zarkesh are asking: Why is that? After decades honing their craft in the industry, older actresses are more talented than ever before, more confident and more attuned to the camera. But cinema is obsessed with the young.

Who doesn't dream of being loved dangerously, thrillingly free from the tethers of restraint? It's a question journalist and author Kate Legge asked after the discovery of her husband's affairs. He was a high-powered media CEO, and she was a veteran journalist who was assured the infidelity was singular (more were to be discovered on the home PC). Having tried (and failed) to keep the marriage going, Kate started to write about it, only to discover infidelities spanning four generations on his side of the family. The resulting book, Infidelity and Other Affairs asks why some choose restraint, while others choose wild abandon.

Harvard University has been running the world's longest study into happiness. The Harvard Study of Adult Development has been running since 1938, and in that time of researchers have observed how Americans experience and understand happiness, and how that's changed over time. In an address for the UNSW Centre for Ideas, the study's fourth director, Robert Waldinger, reveals the study's largest findings, and how technology — and changes in society — have inflected the interpretation of the study's data.

Who sets the agenda when it comes to designing houses? More often than not wealthy developers call the shots. The result is cheaply-made hot boxes, unaffordable to live in, and poorly designed for human habitation. How did it come to this, and how can citizens and architects seize control? Meet 3 international trailblazers who want to change who controls what we get to call home — including an architect from Barcelona who needed an affordable place to call home and had social change on their mind.

In its simplest definition, orientalism refers to the patronising depictions of the 'Eastern world' — a term that encompasses North Africa, the Middle East and Asia — by writers and artists from the West. And it's no stranger to the Australian stage. Major commercial musicals with orientalist underpinnings such as The King and I, Madame Butterfly, or Miss Saigon regularly grace Australian stages, which give a vital leg-up to emerging stage workers. But as more of these workers reflect the multiculturalism of modern Australia, it's prompting a revision of the orientalism embedded in the canon.

Where once photography gave us images of the world as seen by machines, photography under AI gives us images of machine images… seen by machines. Major global companies including Bing and Adobe are heavily investing in generative image models to produce the next AI advance in photography. But in this moment, what has become of the still image? Does it begin with the shutter, or is it now traced from computational models that power the AI-generated image? Hear from a researcher who's made it her mission to consider the value of photography amid the dawn of artificial intelligence.

While Australian women were among the first to get the vote in the world, their lives were still constrained for decades afterward. It was only until 1966 when the marriage bar was removed, which forced women to give up their careers once they married. But despite these constraints, generations of Australian women were able to subvert the system. Australia's first female scientists were among them. It's a history that's recently been collated in a new book. But the question remains… how much has changed for women in STEM?

Your internal experience of consciousness – your rich inner life — has had scientists and philosophers completely perplexed for centuries. How does your brain's 100 billion neurons conjure up that distinct sense you have of being YOU? Is it different to your dog's sense of being a 'doggish'? Could that sense be reproduced in artificial intelligence? What happens when you experience altered states of consciousness - take a psychedelic, go under an anaesthetic, or hallucinate? Neuroscientist and bestselling author Anil Seth and psychologist Olivia Carter are on the case, and join Big Ideas host Natasha Mitchell.

In 1963, as the space race was taking off, the influential political philosopher Hannah Arrendt challenged scientists over their shift away from a humanistic focus to worlds beyond. She was responding to a question posed by the Encyclopedia Britannica: "Has man’s conquest of space increased or diminished his stature?". Replace man with human, and let's ask that question again 60 years on. As we penetrate, populate, and plumb the depths of space evermore.

Mental health problems and chronic diseases are plaguing societies around the world. Both fields need new solutions. We know that lifestyle and obesity contribute to chronic diseases; they can shorten your life by 11 years! But can you use lifestyle to stay chronically healthy? And are we ignoring human rights and social factors in mental health policies and services? For over 40 years a popular response is to prescribe medication. But we are seeing a paradigm shift.

Australians on average chuck out 7.6 billion tonnes of food per year. That amounts to 312 kilos per person, or about $2,500 per household. It's bananas. But in a world that has long prioritised convenience and abundance, disposability has been baked into food chains. But this wasn't always so. In this Melbourne Conversations and RMIT Culture panel, hear from a zero-waste advocates, artists, and foodies about how we got into this mess, and what we could do to get out of it.

In a world of hyper-connectivity and social media, why do so many of us feel so damn lonely? Being lonely isn’t the same as being alone, and some people love their solitude. But loneliness is widespread, growing, affects all ages, and seriously sucks for your physical and mental health. Why are we so ashamed to talk about it, and what can help? Four guests join Big Ideas host Natasha Mitchell for a frank, fearless and moving conversation about a very modern challenge.

Many people embark on a journey to discover their family's past in order to contextualise their present. But what happens when that journey uncovers something unwelcome? This was the case for the award-winning Australian writer David Marr. His great great grandfather, Reginald, was an officer of the Queensland Native Police — a force whose task it was to hunt and kill Indigenous people. This discovery has informed David's latest book, Killing for Country: A family story, which traces the structures that supported the violence of Australian settlement. Join David in dialogue with anthropologist and geographer, Marcia Langton, whose ancestors were murdered by the Native Police. Please note this discussion features distressing discussions of massacres against First Nations Australians. For further assistance, contact the free, 24-hour Aboriginal and Torres Straight Islander counselling line 13 YARN (13 92 76).

What happens when Australia’s best poets and writers walk into the world of scientists? How do they feed of each other’s brilliant, inventive minds to help us understand one of the most challenging experiences of our lives ... watching a loved one slowly lose their mind?

A range of media outlets — including the ABC — have been criticised for their coverage of the latest Israel-Gaza war. There have been protests, apologies, and retractions from the likes of the BBC and CNN. But in a moment where it is notoriously difficult for foreign journalists to gain access to Gaza, what are the obligations of news media when reporting on the Israel Gaza war?  Responsibilities of the News Media on Palestine was a University of Technology Sydney webinar, first recorded on November 10, 2023.  Note: This is part two of the discussion. Listen to the first part here.  Speakers:  Monica Attard Co-director of the Centre for Media Transition, UTS, and former ABC broadcaster and foreign correspondent Amy McQuire Journalist, editor, and PhD candidate at the University of Queensland Antony Lowenstein Journalist, film maker, and author, The Palestine Laboratory: How Israel Exports The Technology Of Occupation Around The World Martin Newman (moderator) Journalism lecturer and coordinator of media law and ethics, UTS

There have been protests, apologies, and retractions from the likes of the BBC and CNN. But in a moment where it is notoriously difficult for foreign journalists to gain access to Gaza, what are the obligations of news media when reporting on the Israel Gaza war?  Note: This is part one of the discussion.

Multi-award-winning Australian photojournalist Andrew Quilty went to Afghanistan on a two-week assignment. He stayed for 9 years. At just 25, Afghan-born women's activist Zahra Karimi found herself facilitating a 5000-strong network of Afghan women. As the Taliban took over in August 2021, and the Republic of Afghanistan crumbled, both had to get out of the country they loved. With a mass exodus, came a mass deletion. Websites, files, records, social media accounts were all wiped to protect people from persecution by the Taliban. So who will tell the stories of Afghanistan as it was before authoritarian rule? Andrew and Zahra want those stories to be heard by the world. They join Big Ideas' host Natasha Mitchell at the Shrine of Remembrance in Melbourne.

Technology's default setting is 'male' — more precisely a white, or at least, light-skinned male. Tracey Spicer exposes how technology and AI has embedded sexism and racism into the future. It's the next frontier of feminism. But who is responsible? Big Tech, refusing to spend money to fix the problem? The world's politicians, who lack the will to legislate? Or should we all be taking a good, hard look at ourselves?

In 2020, veteran science journalist Ed Yong intended to write a book about the world of animal senses. But fate had other plans — he was put on the COVID beat for The Atlantic, and later received the Pulitzer Prize for his efforts. But year later he returned to the book and rediscovered an immense world: Flowers growing in electric fields, bees seeing in ultraviolet, the underwater symphony of the Great Barrier Reef. The sublime in the natural world. In his latest book, An Immense World: How Animal Senses Reveal the Hidden Realms Around Us, Ed asks how animals can sense this when we can't.

University should be a place that nurtures big ideas; where curiosity and creativity thrive. But are our universities struggling with a lack of imagination? Increasingly, higher education in Australia has become transactional, relying heavily on students to bring in revenue. But if Australian universities are to meet the challenges of the future, is it time to rethink the current business model and think more boldly about the purpose and value of universities?

If you find yourself locked up in a foreign prison on fake charges, what would you like your government to do? It's a question that rollicked around economist Sean Turnell's brain when the unthinkable became reality. In November 2021, Myanmar's military junta arrested Turnell — then an economic advisor to Aung San Suu Kyi — and thrust him into solitary confinement. He would be wrongfully imprisoned for another 650 days in one of Yangon's most notorious prisons. This is the story of how Turnell survived that time, and how a global coalition worked to set him free.

Has feminism been too white and too middle-class for too long? From India to Australia, five trailblazing women spanning generations, geography, and cultures join Big Ideas host Natasha Mitchell to give their frank and fearless views  on the F Word — what it means to them and how it might evolve.

The road to peace is one littered with compromise. From Belfast to Bosnia, Dili to the Democratic Republic of the Congo, peace negotiations after bloody armed conflict have involved incredibly complex choices between what to prosecute and what to pardon. So what would you give up to obtain a lasting peace? This Big Ideas episode was first broadcast on November 10, 2015.

He was one of the most remarkable producer/director/actors to come out of Hollywood. The cinema wunderkind George Orson Welles. But he was also a troublemaker and outsider; maybe too creative and eccentric for his own good. Some of his work remained unreleased, and at the same time his movie Citizen Kane is studied as an epitome of cinematic art all over the world to this day. Big Ideas discusses the legacy of Orson Welles, and the struggles to make Citizen Kane.

The director of Doherty Institute for Infectious Diseases was out of office when the first official case of the novel coronavirus was declared. At the time, Sharon Lewin was hiking in remote Patagonia. Then she got a call. Her deputy, Mike Catton, confirmed that Doherty scientists were the first outside of China to grow the novel coronavirus in a lab. This is the inside story of how that was achieved, and the split-second decision making that changed the course of the COVID-19 pandemic forever.

Clem Ford, author of bestselling book Fight Like a Girl, Boys Will be Boys, and How We Love, is back with a firey new read. This time she's taking on an age-old institution that she argues harms women, and has throughout history. She wants marriage abolished. From white weddings to wandering wombs, coverture to capitalism, I DON'T: the case against marriage is full of stories of resistance, rage, and re-imagining. It'll shock and rile some, for others it'll be a case of hard relate. Clem Ford is in conversation with Big Ideas' host Natasha Mitchell at the Athenaeum Theatre in Naarm / Melbourne.

There is nothing like cheering on your favourite sport team; or seeing our Aussie athletes on the top podium at the Olympic Games. A whole nation celebrates. Strangers are falling into each other's arms. Sport can truly unite us. But then… there are racist smirks, fans getting violent. Even in high school can you get a hard time if you're wearing the wrong club colours. So, does sport in fact divide us?

While it was Mao Zedong who believed power came from the barrel of a gun, philosopher Hannah Arendt saw it differently. Instead, she believed the eruption of violence was less a testament to power, but rather, a stark admission of its absence. These thoughts later culminated in her 1970 essay, On Violence. More than a half century later, can Arendt's insights make sense of our turbulent present?

How can you quiet those nagging voices inside your head; expectations that you should to better; anxiety how to make ends meet with rising costs of living … or trying to cope with abuse, trauma and loss? How can you turn your 'inner wilds' into 'inner calm' and achieve a more peaceful way of being? At the top of the list: Have compassion toward yourself and be kind to yourself — as well as others.

Sometimes an event so big happens that it leaves everyone gasping in its wake. In this case, more than million fish were left gasping too. A stunning story of how one community rallied. At its heart is healing country, art, science, and ancient knowledge. In the Summer of 2018-2019 and again in 2023, mass fish kills left communities along the mighty Baaka / Darling River — one of Australia's most important river systems — devastated. The scenes of floating white carcasses captured attention worldwide. What happened next? And how were lives transformed in the process?

The witch is a figure that has been around for a long time in many cultures, stretching back to ancient times. In the West, witches have re-appeared in stories for centuries: from Macbeth, to Salem, to Sabrina the Teenage Witch. But in the 21st-century, witches — and the practices associated with them — are being re-appraised, both as a form of contemporary spiritual practice, and a frame to study historical crimes against women.

To write history is to omit. The historical archive is the end-product of a series of choices, and in the wash, particular voices get privileged over others. But around the globe, historians are attempting to identify the gaps in 'official' history, and in so doing, understand how and why they were created. Santilla Chingaipe is among them. Her recent work has told the stories of the hundreds of convicts of African descent transported to Australia during colonial rule. In her 2023 EW Cole Lecture for the Wheeler Centre, Santilla asks the question: Who gets to write history?
