Welcome to episode 13! Some would call it unlucky, dangerous even, and to others, it’s just another number. But why 13? What did the number 13 ever do wrong, and why do we feel things are unlucky? In this episode, I want to explore why humans turn randomness into story and superstition; and is luck a real thing at all, or is maths and probability actually behind everything? There will be history, maths, and a bit of psychology, all to ask: what does ‘unlucky’ even mean?

Rare, beautiful, and almost magical. A rainbow is one of the few natural phenomena that doesn’t need any explanation to make you go ‘wow’. But understanding why it happens makes it even cooler. In this episode, we are taking a deep dive into a piece of physics magic: rainbows. How and why do they form? Why are they that shape? And could you ever find the end of a rainbow?

Light is great. It’s beautiful, a symbol of hope, positivity, knowledge, and imagination, and of course we need light here on Earth to survive. However, you can have too much of a good thing, especially when that thing is created by humans. This episode, we are looking at the impacts of artificial light on the environment, and on our ability to observe the cosmos, and how that affects us on Earth. This is the dark side of light.
