Carcast Robin and Brian's Loungecast

Very early morning flights have meant a lack of Loungecasts in the last week, but now Robin and Brian are back, with a Carcast as they travel from Sydney to Canberra. There's show tunes, strawberries at the heat death of the Universe, the physics of Interstellar and more. And if you're a fan of maths being done live in a car in a loud tunnel, you are in for a real treat.
