This is the second of the books about science communication / science in society that I’ve been meaning to read for years but never gotten around to. (The first was Randy Olson’s.) I’m now motivated to read them in light of the dramatic switch in the governance of my country, in hopes of gleaning lessons that will allow me to effectively promulgate reason and evidence-based decision making. The book documents …

For your Friday fold this week, I present to you a 3D model of a sample of kinked schist from Beavertail State Park, Rhode Island. Spin it right round, baby: This is another sample from the structural geology collection of Carol Simpson and Declan De Paor.

I just finished Richard Dawkins’ book for younger readers and/or a general audience, The Magic of Reality. It’s a general-interest science education book, written in Dawkins-speak – very conversational and emphatic about key points. It consists of a series of chapters about different topics, with each chapter guided by a big question, like “What is a rainbow?” or “What are things made of?” or “Who was the first person?” Dawkins …

I recently discovered a terrific series of videos on YouTube called “Kate Tectonics.” Watch episode 2, “The History of Geology,” here, to get a taste of the series’ excellent production values and its hip, humorous style: I asked one of the creators, namesake Katelyn Salem, to share a bit of information about the series: Who’s involved in the series? The credits seem lengthy! Can you give a bit of …

Garnetiferous beds from the aureole of the Leinster Granite east of Baltinglass, County Wicklow, Ireland (Declan De Paor’s senior thesis mapping area, 1973). Manganese-rich metasediments. The prominent ‘elasticas’ or fan folds (folds with a negative inter-limb angle) are superimposed on isoclinal folds: so the brownish layer at top and bottom are the same, though that is not obvious from the image. This is a sample from the structural geology collection …

With the current political climate being what it is, I’m newly motivated to learn the best way to communicate science with the American public. I’ve decided to read several books on the topic that I’ve been aware of for years, but not yet made time for. The first is Randy Olson’s Don’t Be *Such* a Scientist. Olson has a unique perspective to apply to the question: he was a tenured …
