Part two of our crusade into the weirdest of quantum weirdness sees us delve into Bose-Einstein condensates, super-solids, quark-gluon plasmas and on into the densest parts of the universe where mountains can fit inside teaspoons. Grab your cutlery drawer, and buckle up!

This week we're taking a left turn out of weird, straight into the downright exotic. Yes, it's time for part 1 of our cruise through some of matter's most exotic states, and the quantum weirdness that gives rise to them. We'll even discover that levitation is a real thing, but it's way cooler than you ever imagined.

The third and final part of our quest to tune into radio technology, explores the move from analogue to digital transmission, and how that made it possible for us to enjoy clear phone calls and pictures of cats on our cell-phones. With the result that the air around us is now an ocean of ones and zeroes, zipping around the world.

How is it that you can hear our soothing tones as they waft gently though your headphones? Join us for part 2 of our guide to radio to find out how technology allows us to speak around the around the world without shouting.

That slab of glass and plastic in your pocket only exists because of 170 years of heroic scientific innovations in the field of radio. Join us as we tune into the amazing evolution of radio technology, including Marconi's stunning discovery that invisible waves bounce around the world.

The second part of our quest to understand the human immune system gets to grips with the superhero that is our adaptive system. It custom builds an army for every invader it meets; even ones it never saw before. And the key to it all is a locksmith who can open every lock that will ever be made.

There's an ancient war that's been going on for millions of years. It's a never-ending quest to keep invisible invaders at bay, and you are one of it's battle-hardened heroes! Join us this week for the first part of our tour around the fantastic human immune system, where we'll discover why a hot battle is a good battle.

In this stellar episode our two hosts try to take the confusion out of nuclear fusion. It makes the stars shine, but what is it, and why are governments around the world trying to tame it? Along the way we'll discover that the holy grail of limitless energy may indeed be a donut!
