Well, even if the OED defines them as such, neither the September equinox nor the just-past March variety actually counts an exactly symmetrical twelve hours of daylight and darkness. Often, the fussy details of things in astronomy (like whether an equinox is labelled as spring, or just March) are related to an observers location on Earth. This time, though, it mainly matters that this was only the spring equinox if you live north of the equator, so identifying it by its month is less hemisphere-centric. Which is absolutely a word.

One of the things I really like about Corvallis is that so many different trees flourish here; there are at least two different kinds of walnut within a block of our house. We’ve harvested some already for eating, but there is a slightly menacing corollary of that bounty manifesting itself about this time of year. As if the hazards of being hit by a falling walnut or having your feet roll out from underneath you on a carpet of them wasn’t bad enough, when shedding fruit in great quantities, these trees draw crows in flocks large enough to qualify as Hitchcockian.
In attempting to devour the crop, crows can be seen trying to crack walnuts by attempting to pin them between their feet to peck at, or drop them from lamp posts, or wedge them in the manhole cover, or (my personal favorite) hurl them at human interlopers. Displaying an amazing variety of tactics, and using elements of the natural environment to their advantage, as well as (superficially, at least) learning from past mistakes presents something very close to empiricism.

Generally speaking, it is unusual for ‘economic stimulus jobs’ and ‘underwater robots’ to appear in the same sentence. For a month this summer, though, those two concepts went hand-in-claw at a camp organized by Linn-Benton Community College staff and students. As a part of the Oregon Underwater Volcanic Exploration Team, high school students from all over the state received training in job skills like electrical circuit design, budget-keeping, and geographic information systems as they built and operated research submersibles called ROVs. The high schoolers were nominated by teachers and counselors in their home towns, and spent six days camping on Paulina Lake inside Newberry National Volcanic Monument east of LaPine. Each student designed and built their own ROV, which they got to take home at the end of the week. Money for the project came from a grant by The Oregon Consortium and the Oregon Workforce Alliance, by way of legislative money for job training in Oregon, where high-tech job growth requires constant workforce training.

Well, if I can say something without jinxing it, it appears as though our two weeks of winter may be over. Not but what it won’t be grey and rainy for a while yet, but the incipient buds are swelling more greenly on their socially networked branches. The leaves cluttering the sidewalks are from the sweetgums, and most of them only just fell within the last month. We’ve had some sunny warmth here and there, and while I haven’t seen any hummingbirds yet, the Steller’s Jays have been joined by squads of robins.
But the thing that really brought a sense of seasonal change for me was at the end of the cold snap we had in December. Hardly seems fair of me to use that term, when Fairbanks has been pretty chilly by comparison, but people take notice when we get a weeks worth of heavy frosts in Corvallis. At any rate, on about 29 December, I woke to find cirrus clouds covering most of the sky, and causing a strong, beautiful 22 1/2 degree halo around the Sun. I’ve long since given up any pretensions to being able to photograph such phenomena, so I contented myself with staring upward for several blocks on the way to work.
