Interview with Dr Tana Joseph

Posted on 22 Oct, 2019 by Allen Versfeld5 Dec, 2019

This is episode 9 of the 2nd season of the Urban Astronomer Podcast, featuring an interview with Dr Tana Joseph. It’s been an interesting two weeks since the last episode – I’ve settled further into my new home and adjusted from rural to suburban life. What I gained in access to basic utilities and saving several hours off my commute has been paid for with a loss of the sky – not to light pollution, but to a canopy of … Continue reading →

Why did I defend the geocentric model?

Posted on 8 Oct, 2019 by Allen Versfeld5 Dec, 2019

Diagram of Copernicus's answer to the geocentric system

In this eighth episode of the second season, I defend my defense of the Ptolemaic geocentric system of crystal spheres! I hadn’t even realized till I started recording that this is our 50th ever episode. I really should be so blown away that I’ve kept things going this long, but I’m not, somehow? Perhaps it’s just become a habit, and I stopped noticing milestones! But anyway, 50 episodes, I think that’s pretty amazing and I’m very proud to have made … Continue reading →

Interview with Dr Jarita Holbrook

Posted on 24 Sep, 2019 by Allen Versfeld5 Dec, 2019

In Episode 7 of the second season of the Urban Astronomer Podcast, I chat with Dr Jarita Holbrook of the University of the Western Cape about her interest in cultural astronomy. This was one of the longer and more interesting interviews of my career, and our conversation continued for some time after the microphones were turned off! Unfortunately, the audio quality isn’t as good as I’d hoped. There’s a terrible echo on my voice which comes and goes as the … Continue reading →

Why are planets always round?

Posted on 16 Jul, 2019 by Allen Versfeld15 Jul, 2019

Welcome to the second episode of this second season of the Urban Astronomer Podcast! Two of Two, sounds like it should be special… and it kinda sort of is, because this week we’re presenting the first of our unique patented Science Explainy Bits!

Posted on 2 Jul, 2019 by Allen Versfeld12 Aug, 2019

This is Episode 1 of our brand new second season! This is the 43rd episode since the podcast was first launched, back in February 2017, and I’m thrilled to be back on the air with you.
