The Greywacke, by Nick Davidson

Just finished a geologically focused book that the readers of this blog might be interested in. It is a history of work on delineating the early part of the Phanerozoic timescale in Wales and Scotland. The majority of the book is about Adam Sedgewick and Roderick Murchison and their close collaboration and increasing divergence and … Read more

Book report

Five books get the Callan mini-review treatment: two novels from Amor Towles, an account of life in prison under solitary confinement, a history of Virginia slavery during the War of 1812, and finally a family account of the discovery of the fossil Hesperornis, a toothed bird, and various associated tangents.

History of Science: Antiquity to 1700, by Lawrence Principe

My most recent commuting audio has been this course from The Great Courses: Johns Hopkins professor Lawrence Principe‘s History of Science: Antiquity to 1700. I checked it out from my local library: 36 lectures, each about 30 to 45 minutes long. I found it quite interesting, well-paced, and insightful. Principe is an organic chemist-turned-historian-of-science, and … Read more

How We Got To Now, by Steven Johnson

I was very impressed with Steven Johnson’s The Invention of Air when I read it last summer. So recently, I decided to sample another of his books, this one a six-part microhistory about innovations that altered the course of human history. The six are: 1) cleanliness/hygiene (specifically in medicine and drinking water), 2) measurement of … Read more

A New History of Life, by Peter Ward and Joe Kirschvink

Yesterday, I finished listening to the audiobook version of A New History of Life, by Peter Ward and Joe Kirschvink (2016). This book is only a couple of years old, and takes as its topic ‘the modern perspective’ on life’s long history on Earth, using the latest insights available. It aims to debunk old hypotheses … Read more

Friday folds: the Roman Forum

When in Rome, do Friday folds as the Romans do? Here are some images from my brief, sweltering visit to the Roman Forum(s) this past summer. The whole region is a jumblepile of ancient ruins in a thousand styles. Almost nothing is labeled. It looks like this: This particular building held up a bit better, … Read more

Great Surveys of the American West, by Richard A. Bartlett

After reading Passing Strange, I found myself wanting to learn more not only about Clarence King, but also about the other great surveys of the American West – those of Hayden, Powell, and Wheeler. I’ve read Powell’s account of descending the Colorado River, and I’ve been delighted this decade past to explore Hayden’s territory in … Read more

Passing Strange, by Martha Sandweiss

Clarence King was a legend. He led one of the four great surveys of the American west (along with Wheeler, Powell, and Hayden) and eventually convinced Congress to establish One Survey To Rule Them All, an institution that ended up being called the United States Geological Survey. King was its first director, but he didn’t … Read more

1984, by George Orwell

My latest book review is of a cutting-edge new novel that describes our current political dystopia in excruciating detail…                                         Just kidding! Seriously: I was spurred to re-read Orwell”s 1984 after last November’s election, and the counterfactual customs … Read more

Hidden Figures, by Margot Lee Shetterly

I haven’t yet seen the blockbuster movie Hidden Figures, but I’ve heard great things about it. This post is about the book it’s based on, also called Hidden Figures, by Margot Lee Shetterly. It chronicles the work of numerous African-American women at NASA and its predecessor organization, NACA, through the middle of the last century. … Read more

Making “Kate Tectonics”

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: [youtube=”https://www.youtube.com/watch?v=EjnsLu6RyYU”]   I asked one of the creators, namesake Katelyn Salem, to share a bit of information about the … Read more

Hate trumps love; Ideology trumps science

It’s been a week since Donald Trump defeated Hillary Clinton in the race for the President of the United States. I’ve been processing the news, and I’m not happy about it. I’ve been on “radio silence” for a week, mourning, ruminating, fretting. From my perspective, this is one of the most disturbing developments in the … Read more
