This week, James Randerson and the Science Weekly team get a tour through biodiversity and conservationism with EO Wilson, one of the world's most influential living biologists.
Wilson's a legend in the fields of biodiversity, entomology, and ecology, and also an all-round advocate for environmentalism. He's one of the world's leading humanists, and here at the Guardian, we described him as 'Darwin's natural heir'. You can hear the full interview as this week's Science Extra podcast.
Also in the show, Bobbie Johnson and Nell Boase pay tribute to Arthur C Clarke; we ask why Michelangelo's David is feeling mighty stressed; and philosopher AC Grayling gives us his Thought for the Pod on the science of learning.
Finishing us off is the one and only Jonny Berliner with a song all about Heisenberg's uncertainty principle. Really.
