The History of Chemistry

• 175: It's All Fun and Games Until...

  Chemistry can be fun, too, so we explore some of historical satirical art about chemistry, humor based on nonsensical molecular structures, actual compounds with funny chemical names, and even compounds with humorous molecular structures. We discuss chemistry-related parody songs, plus a bonus of me singing an actual song from 1901. We hear of some chemistry games designed to teach students. From there we move on to chemistry dad jokes and puns (hey, I am a dad), and chemistry in the Journal of Irreproducible Results and the annual Ig Nobel Prize.

• 174: Just Add Water

  Water, the most important chemical for us, deserves its own episode describing the history of how chemists understand it. We start with pre-Enlightenment views of water as an element, then as a compound, then how electricity affected our understanding, then with dissolved salts, the crystal structure of ice, water's actual molecular structure, and how hydrogen bonding affects it.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 173: Midnight Blue

  We start with a 1927 patent awarded to George Washington Carver, an agricultural chemist, for a locally-sourced Prussian blue. We learn a bit about Carver's life, education, and hobby of painting which may have led to the patent. We examine the patent in some detail, and then hear how it's been revived by a modern artist. Then we discuss other blue pigments throughout history, ending with the newest blue, an accidental discovery in a laboratory in 2009.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 172: A Life of Its Own

  In which we discuss the history of scientists attempting to determine a half-life of a specific radioactive isotope of samarium, and why that determination is so important for other branches of science. We learn of the poor quality of the observation, how at least one result was retracted, and how a new way to measure half-lives offers hope for a resolution to this problem.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

• 171: Talk Dirty to Me

  This is a brief history of how chemists understand the way liquids wet things. The first glimpse was by Francis Hauksbee in the early 1700s, and how water rises in narrow tubes. Through the 18th century, natural philosophers described surface tension. The 19th century brought understanding of wetting via macroscopic observations and descriptions. The 20th century added insights of quantum mechanics and the influence of surface roughness. Finally we discuss the 20th-century observation of superhydrophobicity, both natural and eventually artificial.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!
