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.

156: Quantum Love
We hear about the recent history of quantum computing to do quantum calculations on molecules. First we briefly discuss different types of computers. Then we talk about the kinds of calculations chemists want to do with quantum computers. We also learn about some ways chemists currently use to simplify the mathematics for quantum calculations.

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 Hoyle, H. Beam Piper, and many others. We talk of "Star Trek," "Battlestar Galactica," and David Foster Wallace.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

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 move forward through the 1960s and 1970s, till actual quasicrystals were discovered in the 1980s. Then we reach the point where natural quasicrystals were found. Then we hear about some of their potential uses.Support the show Support my podcast at htt...

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 heating up without oxygen. We also learn of new methods to mine plastics for hydrogen as fuel.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

152: Built to Last
We give a "solid foundation" to chemistry by recounting the history of concrete, starting with the earliest architectural use of lime around 10,000 years ago. We continue through ancient history and modern times with Roman concrete, the loss of its recipe, and (partial) rediscovery in the Renaissance. We continue to the present and the likely complete rediscovery of Roman concrete in the 21st century. We talk of the chemical reactions to make and set concrete, and its ecological problems. Fin...

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 Marcos Suero. We add to the mix Mark Levin and Guangbin Dong, talk of what precisely this type of chemistry does, and relate the wish-list of chemists of all the wonderful things that scientists would like in skeletal editing.Support the show Support my podc...

150: The Medium is the Message
We reach the Big 1-5-0, in which I discuss the venerable history of mRNA vaccines, from the 1960s to the present, from a chemical point of view. We hear of transferring mRNA into cells, then transferring anti-viral mRNA into cells. There are a variety of mRNA vaccines under study--not merely COVID, but flu, RSV, and even cancer treatments.

149: It's the Kosher Thing
In this episode we touch on how chemistry has directly influenced religion. Our example is how knowledge of chemistry affected a rabbi's decision to allow a certain brand of carbonated beverage to claim that it is kosher, that is, fit to be ingested by Jews who follow traditional Jewish laws and customs regarding food.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

148: The New Electronics
What if we could make flexible electronics for clothing or medical sensors? We examine the history of this quest from the 1990s onward, focusing on liquid-metal electronics. We explore what that means, the pros and cons, and how it might work. Then we talk about creating electronic components using wood (really!), which began in the 2010s, ranging from wooden batteries to wooden transistors.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your ...

147: Good to the Last Drop
The history of chemistry in water microdroplets is discussed. We start with the observation by R. Graham Cooks that certain chemical reactions went faster inside ultra-small droplets of liquid relative to beaker-sized amounts. We examine the years-long arguments between Dick Zare and Himanshu Mishra over peroxide formation in microdroplets. We talk a bit about some reasons why reactions may go differently in tiny drops versus bulk amounts, and counter-arguments.Support the show Support my pod...
