Currently listening to Wake Up and Dream - Radiolab (also known as the coolest podcast to ever exist).
Alice wonders about mirror milk (by Meg Hunt)
If you do not already listen to Radiolab, please do RIGHT NOW. It’s a super-intriguing podcast that breaks down these really big ideas (sleep, falling, symmetry, etc.) into groups of anecdotes from scientists and regular people, making you think about these average, everyday concepts in mind-blowing new ways.
Or you could just follow them on tumblr until they astound you with their brilliance and make you realize that I’m totally right and you go and download every single podcast.
