The History of Chemistry
Chemistry is everywhere, and involves everything. But how did chemistry get to be what it is? I'm Steve Cohen, a chemist and writer, bringing you The History of Chemistry. This podcast explores the development of chemistry from prehistoric times to the present, including the people and societies who made chemistry what it is today. The History of Chemistry is for you, whether you hated chemistry in high school, or got a PhD in inorganic chemistry. We'll explore how chemistry affected art, music, language, politics and vice-versa. Whether it's ancient Greek philosophers, medieval alchemists, or modern laboratory apparatus, it's all here.

163: Basic Fuel
In which we talk about the history of using ammonia, the nitrogen analog of methane, as a fuel. We start two centuries ago with Goldsworthy Gurney, move to the mid-19th century when horseless carriages began to appear in Europe. World War II sp...

162: The Game of Life
Here we talk about how chemists historically have viewed the way life began: as chemicals self-organizing. The earliest serious chemical views began in the 1870s, with synthesis of proteins. Ideas through the decades included warm ponds, auto-c...

159: Suck It Up, Buttercup!
Given the environmental catastrophe into which we now zombie-walk, here is a bit about the history of extracting greenhouse gases directly from the air. Extracting carbon dioxide from the atmosphere began in the 1930s, but proposals to do it en...

155: Sci-fi Chemistry
In which we [cue theremin!] discuss how chemistry is presented in science-fiction stories. We start with Mary Shelley's "Frankenstein," move through Jules Verne and H.G. Wells, then to 20th-century writers like Isaac Asimov. Kurt Vonnegut, Fred...

154: Tile by Tile
We discuss the history of finding quasicrystals, those arrays of atoms that are like crystals--but aren't quite crystals. These are rarely talked about in undergraduate classes. We start with a purely mathematical question by David Hilbert, and...

153: Plastic Arts
We finally return to polymers, but in a more ecological way. We learn about using wood waste to make plastics. We hear of how to make plastic naturally degrade in the environment, whether with bacteria, sunlight, zapping it with ions, or heatin...

151: No Bones about It
This episode relates the history of the new field of "skeletal editing" of molecules. While there have been a few known reactions of this type since the very late 1800s, the general system was unknown till the 21st century, beginning with Marco...
