I had the honor of sitting down with Professor Donna Strickland, Nobel Prize-winning physicist the third woman in history to receive the prestigious award in physics. In our conversation, we discuss her groundbreaking work in laser physics and the journey that led her there. From her early academic interests to the moment she received the life-changing call from the Royal Swedish Academy at 5AM (?!), Donna shares insights into her discovery of chirped pulse amplification (CPA), a revolutionary technique that changed the field of high-intensity lasers. We discuss the science behind CPA and the moment she accidentally broke the fibre optic cable required for her PhD research. Donna reflects on the role of perseverance, collaboration, and the underestimated metric of "luck" in scientific discovery.
In part two of our chat with Dr. Heather Ford, we delve deeper into the hidden dynamics of Wikipedia — the world's largest encyclopedia and 8th most visited website, run largely by volunteers. We explore how pages are updated in real time, yet controversial topics like Indigenous place names often face delays and heated edit wars. Dr. Ford explains how this can lead editors to walk away, raising concerns about who gets to shape history. We also unpack the platform's lack of diversity and the growing influence of AI — with up to 90% of internet content projected to be AI-generated by the end of 2025.

I'm joined by Dr. Heather Ford, ARC Future Fellow and Professor in the School of Communications at UTS, to explore the fascinating world of Wikipedia. Inspired by her article "We analysed 35,000 Wikipedia entries about Australian places. Some of them sanitise history" in The Conversation, we dive deep into the strengths and shortcomings of one of the internet's most beloved resources.
We unpack how Wikipedia works behind the scenes: who edits it, how "edit wars" break out, and why it remains such a radical platform — a place where history can be written in real time, sometimes even before events unfold.
Together, we question whether Wikipedia offers an honest account of Australia's past, particularly when it comes to Indigenous history.
This is a two-parter so be sure to tune in next week for part 2.

In part two of my conversation with Dr. Graham Wild, we dive deeper into the fascinating world of hypersonic machines. We explore how sound waves behave at extreme speeds, the significance of the boundary layer, and what materials are best suited for these ultra-fast aircraft.

Aviation expert Dr. Graham Wild returns to take us beyond the basics of flight and into the high-speed world of subsonic vs. hypersonic aircraft. We break down the engine mechanics behind these incredible machines, and I squeeze in a humblebrag about sitting in an SR-71 (yes, okay, it was grounded).
It's a theory-packed episode, so we've split it into two parts. Catch Part 2 next week.

In 2020, Scientific American made waves with the provocative headline: "No One Can Explain Why Planes Stay in the Air." But is that really true? Dr. Graham Wild, senior lecturer in aviation science and technology at the University of New South Wales in Canberra, joins us to set the record straight.
In this episode, we dip our toes into the complex of flight. We scratch at the very surface of the topic in an episode that could easily take over 20 hours.

Are ice baths really the recovery miracle they're made out to be? We plunge into the science with Dr. Hunter Bennett, lecturer at the University of South Australia, exploring the pros and cons of ice baths, when they're helpful, and when they might actually hinder your gains. We also unpack health misinformation online and Dr Hunter shares five evidence-based tips for anyone curious about cold plunges.

Dr. Brooke Nickel dives into the murky world of health misinformation on social media, exposing how overdiagnosis and unverified health claims are thriving in a mostly unregulated space. We explore the influence of online personalities, the power of personal anecdotes, and the urgent need for evidence-based guidance in digital health conversations.
Award-winning author and investigative journalist Alice Driver joins me to discuss her powerful new book, Life and Death of the American Worker. Her investigation exposes the deeply unethical practices within the meatpacking industry in the United States.
For Alice, this story is personal. She grew up in Arkansas, one of the country's poorest states and home to Tyson Foods, the largest meatpacking plant in America.
We delve into the harsh realities faced by the industry's workforce, many of whom are undocumented immigrants, with estimates suggesting that up to 30% of the labor force lacks legal status. Our conversation explores the severe health consequences these workers endure and the broader implications for workers' rights in America today.

In this episode, Prof. Boris Kuhlmey and Prof. Peter Tuthill join me to discuss the Toliman Mission, a space telescope project focused on detecting Earth-like exoplanets around Alpha Centauri, our nearest star system, using precise astrometric measurements. We discuss logistics, the costs involved and the success rate of such an astronomical project.
Developed by a collaboration including the University of Sydney, NASA's JPL, and Breakthrough Initiatives, it aims to launch by 2026.
