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.

Couldn’t figure out a graceful way to integrate into the last post, but another interesting stance on analysis and information comes from Chris Anderson et al at Wired. If I may summarize with far too much brevity, it is the nth degree (or the reductio ad absurdam, depending) of the dictum that to increase understanding, add information.
While even I think that statement needs qualifiers, it is demonstrably true on most maps. Cf the two pictures below:
