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,

The History of Chemistry ·

2025/09/09

I conclude this series, touching on why I ran this podcast. I give eleven overarching goals for the podcast. I also go far back into my own past, and an event which eventually led to me speaking to you about chemistry. Finally I send you off with an announcement about a national award I will accept in 2026. Please continue to support this podcast, because it costs money to keep this series posted on Buzzsprout and Patreon. Without your continued support, this podcast will disappear from the I...

The History of Chemistry ·

2025/09/01

I give a brief history of finding planets around other stars, including discovery by gravitational wobbling, dimming as the planet crosses in front of its star, and even seeing an actual planetary image by blocking the star's glare. I discuss what sort of spectroscopic signals might be present for life in a planet's atmosphere. Finally I offer some planets already detected whose temperatures appear to be in the range of terrestrial life, and what's in their atmospheres. Support the show Supp...

2025/08/22

We take an imaginary trip around our Solar System to hear the history of chemical attempts to find life, starting in the late 1950s. Among our stops on the tour include Venus, Mars, Europa, and Titan. Included in the tour are temperature measurements, spectroscopic views, gas chromatography, radioactive labeling, photographs, electrical conductivity, and more.

In which we bring research into molecular machines up to date. We discuss fuels, specifically what chemists think are the best kinds of fuels to power these little molecules. We discuss what makes a molecular machine different from a regular-sized machine. We also talk about molecular machines as a subset of "molecular devices." Finally, we mention a poll for researchers that IUPAC has set up to help chemists define what a molecular machine really is. Support the show Support my podcast at h...

Instead of just digging in the ground to extract minerals, over the past half-century scientists have begun to explore agriculture of hyperaccumulating plants to pull elements--including heavy metals--out of the topsoil. We explore the recent history of this topic, its advantages and pitfalls.

While outdoor solar cells make big news, there is a quiet revolution also for solar cells that make do with far less illumination, indoor lighting. We discuss requirements for such photovoltaic cells, matching their sensitivity to various kinds of indoor lamps, and such developments in the last couple of decades. We discuss research into various materials for these low-light panels. Finally, we shift gears and learn about new batteries that work inside bodies, using the body fluids as electro...

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 ...

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.

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.

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.

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 supe...

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.
