Episode 84: Crystals


There are many different types of crystals we encounter, ranging from tiny to extremely large in size. First we learn about sodium chloride and the role it plays during the cold winter months. Next, continuing our cold weather theme, we take a look at snowflakes and different tools that have helped scientists view their unique shapes over the centuries. And finally, our executive producer Michal Meyer talks with crystallographer Karen Allen about her work at Boston University. Chemical Agent: Sodium Chloride.
