Episode One: Reactions Just about every solid, liquid, or gas in the world begins with reactions between individual atoms and molecules. David Pogue dives into the transformative world of chemical reactions, from the complex formula that produces cement to the single reaction that's allowed farmers to feed a global population, a reaction that when reversed, unleashes the powerful chemistry of high explosives. Episode Two: Indestructible Scientists and engineers have created virtually indestructible versions of common materials by manipulating the chains of interlocking atoms that give them strength, but have they made them too tough? Host David Pogue explores the fantastic chemistry behind the everyday materials people depend on, and how the quest for durability can be balanced with products' environmental impact. Episode Three: Live Without the chemistry of photosynthesis, ozone, and a molecule called Rubisco, none would be here. So how did one get so lucky? To find out, host David Pogue investigates the surprising molecules that allowed life on Earth to begin, and ultimately thrive. Along the way, he finds out what all are made of, literally.
