Introducing Galileo

On February 16, 2013 By dava

A handsome new, illustrated edition of Galileo’s great Dialogue on the Two Chief Systems of the World will be published in June, and I was invited to write an introduction.

Of course I accepted. I like introducing other people’s books. It’s something I’ve done perhaps half a dozen times in my life, though never for [...]

Proposing

On January 4, 2013 By dava

No, not marriage. But something very like, for a person in my profession, given the time commitment implied. I’m trying to describe the scope of a new book idea — a project that could consume my life for at least five years — to a potential publisher.

The point of the book proposal is to awaken the [...]

Umbraphilia

On November 27, 2012 By dava

I’d been thinking, en route in early November to Australia for my eighth total solar eclipse, that I’d spent more than enough time and money chasing the shadow of the moon. I figured I’d give up the quest after this one last exposure.

But then the weather on Green Island cleared, after a string of gloomy [...]

Doctor Copernicus in Padua

On October 22, 2012 By dava

On October 15 I had the honor of delivering a lecture about Copernicus’s day job — his lifelong service as personal physician to the bishop of Varmia – in Padua, at the very institution where Copernicus attended medical school early in the 16th century.

I was happy to return to Padua, where another of my heroes, Galileo, spent [...]

Astronomer Vesto Melvin Slipher (“V.M.,” as he was always called) made the pivotal observation at the Lowell Observatory in Flagstaff, Arizona. Using the same telescope through which his boss, Percival Lowell, had perceived canals on Mars, [...]

Final Leap

On August 28, 2012 By dava

Everyone I know mourns the loss this week of astronaut Neil Armstrong. Those of us who saw the live broadcast of the first Moon landing have stood straighter ever since at the mention of his name. Armstrong carried out the combined missions of an explorer, a dare-devil, a visionary, and an emissary for the human race without [...]

Hobbits reach Mercury

On August 20, 2012 By dava

In their quiet, fictional way, hobbits and ents arrived at Mercury this month. They stole no headlines from Curiosity’s successful touchdown on Mars as they slipped into their newfound niche, Crater Tolkien, on the Solar System’s innermost planet.

Crater Tolkien came to light thanks to the year-plus explorations of the Mercury-orbiting spacecraft called MESSENGER [...]

Writers at Risk

On July 13, 2012 By dava

Today is my last day at the West Cork Literary Festival in Bantry, Ireland, where for the past week I’ve enjoyed the luxury of lecturing about my work and listening to other authors do the same. To remind us of our extreme good fortune, teenagers enrolled in a Festival writing workshop appeared at the [...]
