The History of Chemistry

• 168: Chill Out

  Refrigeration always has been closely intertwined with chemistry. In this episode we explore the history of refrigerants, from the first hints of artificial cooling in the mid-1700s, through the invention of the first practical refrigerator 8 decades later. We talk about a variety of refrigerants through the 20th century. Finally we examine some other newer or less-common methods of cooling.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 167: A Sound Idea

  Magnetic tape was an integral part of the new, growing recording industry. Herein we talk about the chemical history of magnetic recording, from the first idea in 1888, onward. We encounter Poulsen, Pfleumer, Stille, Nagai, Mullin, and an array of corporations as well. Finally we discuss a bit about digital computers and the history of magnetic tapes for data.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 166: The Dagwood

  Here we talk about supersized sandwich compounds and their history, beginning with ferrocene in the 1950s. We go from single-decker to double-, triple, and quadruple-decker sandwich compounds through the 1970s and 1980s, a variety of "breads" and "fillings," and then even bigger as we move to the 21st Century.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 165: Building Blocks

  Herein we examine the cubical hydrocarbon, cubane, and its role in chemical history. We talk of difficulties in synthesis, possible uses as an explosive, its use as an isostere to benzene in medicinal compounds, and polymers of cubane.

• 164: Mirror, Mirror

  In which we talk about how chirality, or handedness, has diffused through chemistry since its discovery in the 19th century, starting with Louis Pasteur. We look at work by Arnaldo Piutti and Emile Fischer. We discuss not only organic compounds, but amino acids, proteins, DNA, and inorganic chiral compounds. Ultimately we have to bring up the question of the biochemical handedness of life.
