This week on the show we continue our Quantum for Dummies series, celebrating the International Year of Quantum. Claire takes the “dummy” seat once again, putting Chris, our resident quantum physicist, to the test with questions about the mysterious principle of uncertainty. Plus, we head into the archives to revisit Stu's interview with Dr Ellie Paine who researchers the role kelp could play in capturing and storing carbon from the atmosphere—and the challenges that stand in the way.
