This is a re-airing of a podcast originally released in January 2021.
The theme of this episode is alliances - human, biological and atomic. We start by celebrating the amazing properties of lichen, the symbiotic relationships it forms, how it shaped the earth and simply how beautiful it is to look at.
Then we explore how carbon is able to create such an incredibly diverse range of materials, including soot, diamonds and graphite.
We wrap up by delving into the life of renowned Hungarian mathematician Paul Erdős, the world’s greatest human alliance maker, who wrote research papers with over 500 mathematicians.
On the podcast are Rowan Hooper, Anna Demming and Timothy Revell.
