Early in this photo-a-day thing I tried to get in the habit of bringing the camera with me when I ran errands, to get pictures of random interesting stuff outside of the immediate neighborhood of our house. I fell out of that, though, when it was actually cold, because I didn’t like leaving the camera […]
Here in the US, we’re slowly transitioning to the European system of chip-based credit cards (I got email at work saying that my new card there will actually be chip-and-PIN, wonder of wonders). This is not uniformly distributed yet, though, so about half of the retailers I deal with regularly want the chip, the other […]
This one was a whole bunch of work for one smallish shot… So, in past rounds of “science-y things with my fancy camera,” I looked at the effect of ISO settings and apertures. This time out, I wanted to look at something moving, and the way that it blurs with increasing exposure time. My initial […]
When Kate and I were looking for a house back in late 2002, one of the things that sold us on this place was the back yard. The lot is very deep, unusually so for this part of Niskayuna, so there’s a lot of space in the back yard, and it was pleasantly shaded by […]
I’ve been neglecting the photo-a-day thing for the last week-and-a-bit, but for a good reason: I had a deadline of, well, today, to finish a chapter I was asked to contribute to an academic book. And while I fully realize that actually hitting that deadline is not typical academic behavior, I have A Thing about […]
As mentioned last week, SteelyKid is doing Odyssey of the Mind this year, and her team has elected to build a balsa wood structure. The goal for these is to support the maximum possible weight, and the first step of the testing is to put a “crusher board” on top. This is a couple of […]
When I arrived to pick SteelyKid up the other night, she and her friends were light-saber fighting with long balloons, which is fairly typical of that bunch. While I gathered her stuff up, though, she stopped and twisted her balloon into an animal shape: She got a “How to Make Balloon Animals” kit a few […]
We have a couple of bird feeders near the house, one just outside the bay window in the front of the house, and the other on the side of the house right next to the dining room. (That one used to be farther out in the yard, where it functioned well as a means of […]
SteelyKid is in second grade, and The Pip goes to full-day day care at the JCC, so we get a LOT of kid work sent home– various homework assignments and class worksheets for her, and assorted art for him. A lot of the art is just a few random crayon scribbles on paper, but some […]
Back in the fall, a note came home with SteelyKid about an organizational meeting for an Odyssey of the Mind team for her elementary school. My father coached this for several years back in the 80’s, and one of my sister’s teams went to the World championships (held in Cole Field House at the University […]
