Using Soundwaves To Measure The Sun with Prof. Conny Aerts (470)

Dumb Stuff In Space with Assoc. Prof. Michael Brown (471)

We're living through the great Space Boom and with great innovation comes a lot of whacky ideas... Astronomer and Associate Professor Michael Brown from Monash University joins me to discuss stupid things in space. The conversation dives into some of the more bizarre and ambitious ideas circulating the space industry, from firing villains and radioactive waste in to the sun to deploying giant orbital mirrors to light up Earth's dark side. Brown breaks down why many of these concepts are far less practical than they sound. With over 15,000 satellites circling earth, Brown also examines the promises and downsides of mega-constellations like Starlink, including how they operate and the challenges they pose for astronomers and the environment. It's a fascinating and critical peek in to the intersection of innovation, risk, and imagination in the new space age.

Using Soundwaves To Measure The Sun with Prof. Conny Aerts (470)

In this episode I sit down with Professor Conny Aerts, a pioneering mathematician and founding figure of astroseismology, who reveals how scientists are "listenting" to stars to understand what's happening deep inside them. From oscillating stars to solar sunquakes, she explains how sound waves can measure the sun's size, age and activity. Beyond the science, she shares her remarkable journey from a small rural town in Belgium where she had to attend an all-boys school, the only school near her family home. She was expected to become a seamstress but Conny's dreams were beyond this planet, leading her on a path toward becoming a highly acclaimed asteroseismologist.

How To Die in the 21st Century with Dr. Hannah Gould (469)

We're scared to say the D word! But why is talking about death such a taboo? Dr. Hannah Gould, a cultural anthropologist at the University of Melbourne, joins me to discuss the topic in the wake of the release of her new book 'How To Die in the 21st Century'. The discussion dives in to the modern experience of dying, from the pressures of having a 'good death' to the reality of overly medicalised, 'prolonged dwindling'. Hannah unpacks how death isn't just biological but also cultural and legal, raising the question: When does death officially occur? The conversation is an invitation to rethink death - not as something to fear, but as something we can approach with openness, intention, and maybe even a sense of celebration https://www.hannahgould.com/

How Two Students Fixed the Focus of James Webb from Earth with Prof. Peter Tuthil, Dr. Louis Desdoigts & Max Charles (468)

When a problem with the James Webb Space Telescope left its images frustratingly out of focus, the solution wasn't fixed in space... it was fixed from Earth. At the University of Sydney, PhD students Dr. Louis Desdoigts and Max Charles spent two years rewriting and refining code to recalibrate a critical instrument designed by Professor Peter Tuthill: the Aperture Masking Interferometer. Their breakthrough sharpened the telescope's infrared vision unlocking clearer views of distant worlds, including volcanic activity on Io, one of Jupiter's moons. In a fitting tribute, the pair even got matching tattoos of the hardware they helped fix! Not only did their work restore clarity to one of humanity's most powerful observatories, it also saved NASA the immense cost and impossibility of repairing the telescope in space.

Forensic Science: Fact, Fiction, and Failure with Dr Linzi Wilson-Wilde and Hannah Jarman (467)

This episode features Dr. Linzi Wilson-Wilde and Hannah Jarman discussing the realities of forensic science beyond shows like CSI. Through cases such as the Phantom of Heilbronn case and Lindy Chamberlain-Creighton, they explore how flawed evidence and forensic myths have contributed to wrongful convictions. They also examine common misconceptions around techniques like bite mark analysis, fire investigation, and glass evidence. The conversation emphasises the importance of approaching forensic science holistically, recognising it as just one piece of the broader investigative puzzle. www.epistemicsolutions.com.au/
