A Conversation with Nobel Laureate Professor Donna Strickland (436)
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.

Wikipedia Part Two with Dr. Heather Ford (435)
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.

Wikipedia: The Power and the Pitfalls Part One with Dr. Heather Ford (434)
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. Connect with Dr. Heather Ford on Linkedin https://hblog.org/

Hypersonics Part Two with Dr. Graham Wild (433)
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.

Hypersonics Part One with Dr. Graham Wild (432)
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. Connect with Dr. Graham Wild on Linkedin Twitter/ X - @aerospacedoctor
