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, or any other option, was that I felt that astronomy contained many of the other things I was interested in. To put it another way, I thought that if I didn’t study astronomy, I would regret it, but if I did study it, I wouldn’t necessarily lose touch with the other things I was interested in because they were all part of astronomy, in one way or another.
My degree is actually in astrophysics, and obviously it involved a lot of physics and mathematics. To see how the universe works, you have to understand gravitation, nuclear fusion, thermodynamics, atomic physics, and much more. In addition, to use and design telescopes and detectors, you need to know about optics, electronics, and materials science. Although I started out with very little background in math, I wound up with a minor in mathematics. By the time I had taken all the math classes required for the degree, and a fourth semester of calculus (which I hoped would help me understand my physics classes better), I was only three credits away from a math minor, so I took a class in linear algebra.
Astronomy also has obvious links to chemistry and geology. The story of the universe is, from one viewpoint, the story of chemical evolution, the development of more complex chemical elements as stars turned hydrogen and helium into more complex elements through nucleosynthesis. To study planets and moons, we can sometimes apply what we know about the rocks and weather and geological processes of Earth. Geology also comes into play in other ways. For example, one piece of evidence for the dinosaur-killing asteroid that struck Earth around 65 million years ago is a thin layer of iridium in Earth’s crust. Read more »







If you took Latin, then you probably have a larger vocabulary than the average bear, and you are more likely to have strong opinions on some words you vaguely remember based on Latin roots (cognates). For example, folks are more commonly using “decimate” to mean destroy or devastate, and it annoys the living materia feculis out of me. Decimate originally meant to kill every 10th person, based on the Latin word for 10 (decem), which is so oddly and satisfyingly specific. “Devastate” and “destroy” are already well known and used, so why do they need another alliterative ally in little weirdo “decimate”?



Soon after President Obama moved into the White House, Mrs. Obama set up her vegetable garden. She planted tubers like carrots and turnips, leafy veggies such as spinach and kale, and herbs—thyme, sage, mint, and whatnot. But she did not plant beets. Why? I was quite perplexed and tried to find out the reason. I called the White House but did not get a satisfactory answer. “What the hell are you talking about?” said someone who picked up the phone. Maybe her children do not like them, said my child who was not overly fond of the vegetable. Not like beets? How is that possible? Of all the tuberous veggies available to man, the beet in my view is one of the best and the most poetic. 


Recently, I was waiting to board an American Airlines flight from Boston to Rochester, when, along with ten of my fellow passengers, I was summoned to the desk in front of the boarding gate. There we learned, by listening intently to what the AA gate agent told the first passenger in line, that we were being bumped from the flight, that AA would try to find alternative flights for us, and that we would each receive a voucher worth $250, redeemable on AA bookings, valid for one year.
Wine writers often observe that wine lovers today live in a world of unprecedented quality. What they usually mean by such claims is that advances in wine science and technology have made it possible to mass produce clean, consistent, flavorful wines at reasonable prices without the shoddy production practices and sharp bottle or vintage variations of the past.
