In the first half hour, Professor Geraint Lewis returns with Part 3 of Our Universe and this week asks the intriguing question: how does our universe allow us to be here? He explores the unique collection of molecules that make us us and makes us fit for this universe.

My special guest at 11:00 am is Jane Hazelwood, viola player with the Sydney Symphony Orchestra. I always think of the viola as always the bridesmaid and never the bride. However, it is a wonderful instrument with its own unique sound.

Music this week switches from the universe to violas!

I look forward to your company.
