by Mary Hrovat When I watched the 2019 documentary on Apollo 11, it carried me back not to the summer of 1969, when it happened, but to the mid-1980s, when I was an undergrad. I was eight when Apollo 11 launched; of course I was aware of the space program and the moon landings, but…
by Mary Hrovat Nature has filled the world with “endless forms most beautiful and most wonderful,” in the words of Charles Darwin. We humans, faced with this abundance and variety of creatures, have used our imagination to the full in giving them descriptive and often evocative names. Some animal names are fairly straightforward; the name…
by Mary Hrovat Books about how to write are so frequently described as life-changing and essential (usually by publishers, but sometimes by reviewers) that I was initially unmoved by enthusiastic reviews of Clear and Simple as the Truth: Writing Classic Prose, by Francis-Noël Thomas and Mark Turner. However, the praise seemed to focus on the…
by Mary Hrovat When I returned to school after my first marriage ended, I had to decide what to study. I’d been working toward a degree in history when I dropped out of a community college to get married, but I’d always been drawn to astronomy. One of the reasons I chose astronomy over history,…
by Mary Hrovat The spring ephemeral wildflowers of the Midwest are generally not large or showy. In a relatively short time during one of the less promising parts of the year, these perennial plants must put out leaves and flowers and reproduce, all before disappearing until the next spring. Still, they light up the woods…
by Mary Hrovat I was struck by a sentence in Susan Orlean’s The Library Book: “If nothing lasts, nothing matters.” This line was part of a discussion of memory, the fear of being forgotten, and the value of passing things on to future generations. I share a passion for the idea of continuity between generations…
by Mary Hrovat I wrote the first draft of this post on my typewriter. Like much of my other writing, this piece began as handwritten notes and drafts typed on a nice little portable typewriter, which is a little younger than I am and which I expect to use for the rest of my life.…
by Mary Hrovat In 2018, Earth picked up about 40,000 metric tons of interplanetary material, mostly dust, much of it from comets. Earth lost around 96,250 metric tons of hydrogen and helium, the lightest elements, which escaped to outer space. Roughly 505,000 cubic kilometers of water fell on Earth’s surface as rain, snow, or other…
by Mary Hrovat Before the second was defined in terms of the characteristics of the cesium atom, before leap seconds or leap days or Julian dates or the Gregorian calendar, before clocks, even before the sundial and the hourglass, there were sunrise, sunset, and shadows. I’ve been thinking about timekeeping using shadows because a tulip…
by Mary Hrovat It could almost be a question on a very meta personality quiz: Do you prefer the Myers-Briggs typology or the Big Five personality traits? The Myers-Brigg Type Inventory is a popular tool that was developed outside of the scientific establishment by two women who did not have credentials in psychology. It’s qualitative…
by Mary Hrovat Every October there’s a huge book fair in my town, where used books donated by the community are put up for sale in a large hall at the fairgrounds. It’s no exaggeration to say that it’s a high point of my year. When I walk in and see table after table laden…
by Mary Hrovat It’s a Saturday in May. I’m 17, and I’ve spent the morning washing and waxing my first car, a 1974 Gremlin. I’m so delighted that I drive around the block, windows down, Chuck Mangione playing on the radio. Feels so good, indeed. I’ve successfully negotiated a crucial passage on the road to…
by Mary Hrovat I’m tempted to describe Marion Milner’s book A Life of One’s Own as the missing manual for owners of a human mind. However, it’s not didactic or prescriptive. In fact, it’s useful mainly because it’s nothing like a manual or a self-help book. The book is more like an insightful travelogue by…
