Indestructible: Episode 2 53 min.

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 we depend on, and how the quest for durability can be balanced with products' environmental impact.

Reactions: Episode 1 53 min.

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.

New! Episode 4: Voltage, Current, and Resistance 23 min.

In episode 4 of the series, we look at how electrical equipment is designed to use the right amount of current for the voltage supply that it’s designed for. After a brief recap on electric current (that we examined in Episode 3) we look at what voltage is and how it is measured. We then look at the concept of resistance. At a simple level, some materials are conductors and some materials are insu...
