  • 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 We learn of the poor quality of the observation, how at least one result was retracted, and how a new way to measure half-lives offers hope for a resolution to this problem.Support the show Support my podcast at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!

  • 170: A Clean Break
    In which we talk about the history of fractals and how they relate to chemistry. There is a brief overview of what a fractal is and how it developed in mathematics. Then we talk of how fractals apply to chemistry, including surface reactions, descriptions of molecular structures both artificial and natural, growth of polymers, and even how the concentrations and flows of minerals in streams follow a fractal variation with time.Support the show Support my podcast at https://www.patreon.com/thehistoryofchemistry Tell me how your life relates to chemistry!

Over 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.
